What is AMD?

Age-related Macular Degeneration (AMD) is a devastating retinal degenerative disease that affects the macula, the part of the eye that provides sharp, central vision. Those who suffer from this progressive disease are unable to drive, read or recognize faces. In AMD, vision loss is the result of the death or dysfunction of retinal pigment epithelial cells (RPE) that provide nutrients and support to the light sensing photoreceptor cells in the eye.

There are two forms of AMD: wet and dry. In the wet form of macular degeneration (known as choroidal neovascularization or CNV), abnormal blood vessels grow under the macula and retina. Fluid from leakage of these blood vessels accumulates and cause vision loss or distorted vision. In dry AMD (non-neovascular form) small yellow deposits form beneath the retina, which can ultimately lead to geographic atrophy (GA) or the advanced form of dry AMD. Dry AMD is the most prevalent form of macular degeneration and can be stable for many years without vision loss. Patients diagnosed with GA have severe loss of vision and a tangible impact on quality of life. To date, there is no cure or known treatment options for GA.

Who is at Risk?

In general the global burden of AMD remains substantial as a result of the aging population. Globally, the projected prevalence of AMD in 2020 is 196 million, increasing to 288 million in 2040. The main risk factors for AMD are age and race. Among Americans of European decent, the prevalence of AMD is projected to rise to nearly 5.44 million by 2050 according to reports from the National Eye Institute. A significant increase in the rate of AMD amongst minority populations has also been observed. Most notably, a six-fold rise of AMD has been reported in persons of Hispanic decent.

Other risk factors for AMD include positive family history, smoking, hypertension, high cholesterol and obesity.

How is AMD Diagnosed?

Pay attention to the signs of early disease including distorted vision and your risk factors for developing AMD. Please make an appointment to see your eye care specialist at least once a year if you are over 40 years of age, if you are at risk as a result of ocular and medical history, family history, age, or race and especially if you are noticing vision loss. Your ophthalmologist or optometrist will conduct a comprehensive eye exam, which will include dilated eye exams, visual acuity, and optical coherence tomography (OCT). Following a thorough assessment, your physician will work closely with you to determine the best course of action.

Are There Treatments for AMD?

In general there is no known cure for AMD. However, for the wet form of AMD, drug treatment options include anti-VEGF (vascular endothelial growth factor) therapies. Such therapies reduce the level of VEGF, a protein known to stimulate abnormal blood vessel growth in the retina and macula. These drugs are administered as injections directly into the eye.

Thus far there is no FDA approved treatment available for dry AMD. USC vision researchers, Dr. Mark Humayun and David Hinton, funded by the California Institute for Regenerative Medicine, have recently developed a novel stem cell-based therapy for the treatment of advanced dry AMD. The treatment consists of a patch of RPE cells derived from stem cells that is grown onto a polymer scaffold and implanted behind the diseased portion of the eye. A clinical trial is currently underway to evaluate this potential treatment at USC and is led by Assistant Professor of Clinical Ophthalmology, Dr. Amir Kashani. Enrollment in the phase I/IIa clinical trial is ongoing for this stem cell-based treatment.

What is low vision and who qualifies?

Those who suffer from low vision experience a dramatic decrease in quality of life, as a result of decreased visual acuity, contrast sensitivity or poor visual fields. Generally, patients who have a visual acuity of 20/70 or worse in the better seeing eye, restricted visual fields, are no longer able to correct their vision through prescription glasses, contact lenses or medical intervention qualify as a low vision patient. Many serious eye conditions such as age-related macular degeneration, glaucoma, diabetic retinopathy and retinitis pigmentosa can cause low vision.

What does quality of life mean?

Quality of life is an indicator of how well an individual is able to effectively and independently carry out daily activities such as driving, reading, cooking and cleaning. It is not just about reading the small print, those who suffer from low vision can experience depression and anxiety without some form of intervention.

What is low vision rehabilitation?

At the USC Roski Eye Institute we believe in a personalized-care approach. Each patient I meet will have a customized plan according to his or her own unique lifestyle. General components such as determination of difficulties in activities of daily life, functional vision and visual field assessments are all a part of the initial evaluation. Based on the results, we will devise a plan that is best suited for you, which may include visual aids as well as counseling or training to improve quality of life.

What kind of treatments or devices are available?

After determining an appropriate eyeglass prescription and other factors such as contrast sensitivity, I discuss with the patient which device or assistive technology would be best suited to enhance their ability to perform daily tasks. I train patients on how to use devices offered by the eye institute such as magnifiers or telescopes. As well, I teach patients how to use assistive technologies like cell phones or tablets. USC Roski Eye Institute has also had a long-standing relationship with visual aid partners and many community organizations to offer additional resources.

Are there changes we can make now to improve our quality of life with low vision?

There are many things you can do to navigate and perform tasks better on a daily basis. You can find several tips on our website but here are a few things you can try:

  1. Improve lighting and never work in a dark room
  2. To reduce glare use shades or covers for shiny surfaces
  3. Color code things
  4. Use scissors in the kitchen in place of knives
  5. Use pill organizers for medication
  6. Download menus on your tablet before going to the restaurant
  7. Order large print labels from the pharmacy, financial statements or checks

February is National Age-related Macular Degeneration/Low Vision Awareness Month

IMG_1144Low vision can affect one or both eyes and be caused by aging, birth defects, injury or complications from disease. Those who suffer from vision loss lose their independence and experience a poor quality of life. Everyday tasks such as using a cell phone, driving, reading a favorite novel or even watching the grandchildren play, become challenging and often impossible.

USC Roski Eye Institute Low Vision Rehabilitation Service

The USC Roski Eye institute is committed to enhancing the lives of those diagnosed with low vision. USC Roski Eye Institute brings hope to those who suffer from low vision with new vision rehabilitation services. Assistant Professor of Clinical Ophthalmology, Rachel A. Young, O.D., offers several services such as prescription eyewear, magnifiers or filters and other forms of assistive technology to treat low vision. Patients are also offered personalized counseling or training to improve their general quality of life.

In addition physicians and residents are educated in the diagnosis and treatment of low vision. Dr. Young organized an annual low vision symposium for USC Roski Eye Institute residents. Vision rehabilitation specialists were invited to discuss the latest in low vision treatments. Numerous medical device suppliers also demonstrated the newest technological advances in vision rehabilitation devices.




USC Roski Eye Institute Making a Difference in the Fight Against AMD

AMD blog photo

Researchers at the USC Roski Eye Institute have made great strides in the treatment of vision loss caused by devastating diseases such as age-related macular degeneration (AMD). Mark S. Humayun, MD, PhD, and David R. Hinton, MD, received nearly $38 million from the California Institute for Regenerative Medicine (CIRM) to develop a stem cell-based treatment for AMD. AMD affects over 1.75 million people age 50 and older in the United States. The leading cause of blindness and vision loss among the elderly, AMD is a central retinal disease that impacts the area of the eye that helps process images, leading to catastrophic vision loss. It targets central vision, resulting in the inability to read, recognize faces or even drive. The disease causes a loss of crucial retinal pigment epithelial (RPE) cells, which are essential to the survival of photoreceptors (light sensitive cells). To restore those RPE cells, the USC Roski Eye Institute team developed a unique procedure to grow thin sheets of stem cell-derived cells to be surgically implanted in the eye, replacing diseased sheets and restoring photoreceptors needed for vision. Phase 1 human clinical trial at the USC Roski Eye institute has already begun.

Extreme Diet Leads to Permanent Vision Loss in 11-Year-Old Boy

VAD Blog

An 11-year-old Canadian boy suffered vision loss from a rare case of vitamin A deficiency (VAD) as reported in the Journal of American Medical Association of Pediatrics.

Parents of the boy of east-Asian descent took him to the hospital over growing concerns that his vision was worsening over an eight-month period. In addition to vision loss, the boy also complained of dry eye.

Ophthalmologists found that the child had a restricted diet of potato, pork, lamb, apples, cucumber, and Cheerios due to his eczema and numerous food allergies. His vision was hand-motion only. Upon examination of the cornea, which is the outermost part of the eye responsible for refracting or focusing light, it appeared that there were opaque patches and inflammation.

After blood work was conducted, physicians found that the boys vitamin A levels were significantly below normal, measuring at 14.33 μg/dL (normal range, 25.79-48.71). The patient was immediately treated with high doses of vitamin A. While vision loss from VAD is often reversible, in this case, the boy suffered permanent vision loss due to optic atrophy or damage to the optic nerve.

“Conditions like this are rare in developed countries, and are thus often observed in underdeveloped countries where malnutrition is prevalent. You should always consult a physician before restricting your dietary intake. In general, having a proper diet rich in nutrients such as green leafy vegetables, omega fatty acids, zinc, lutein and carotenoids can have an impact on preserving healthy vision,” says cornea specialist, Jonathan Song, MD, MBA, Associate Professor of Clinical Ophthalmology.

According to data provided by World Health Organization, VAD is the leading cause of preventable blindness in children and affects one third of children aged 6-59 months in underdeveloped countries in 2015 (see map below).

Model Risks Losing Eye after Tattooing it Purple

A model in Ottawa, Canada made the decision to tattoo her eye purple, as it was her favorite color. Very quickly she realized something was wrong when the purple ink began to leak from the white part of her eye. Experiencing excruciating pain, her eye began to swell and become infected.

In recent years, the procedure of scleral staining or episcleral tattooing has become an emerging trend. The sclera is the white outer layer of the eye. It is significantly more porous and thinner than skin. As a consequence, these dyes and inks can easily diffuse through the sclera and reach the fragile visual processing structures inside the eye. According to a report in 2015, episcleral tattooing can result in headaches or photophobia (light sensitivity) to more severe complications like infection, hemorrhage or even direct penetration into the eyeball.

“Eye tattooing is not recommended as it is very dangerous and can cause serious complications. Once inside the eye, these chemicals will wreak havoc because of their innate toxicity and will most certainly lead to devastating visual loss,” says Charles W. Flowers, Jr. MD, Associate Professor of Clinical Ophthalmology at the USC Roski Eye Institute.

The ophthalmologist who treated model Catt Gallinger, observed a scleral tear from the large needle used to stain her eye as well as a severe infection. Gallinger received grafts and has permanent vision loss from this procedure.

Having posted multiple times on Facebook, Gallinger has brought greater awareness to the dangers of undergoing episcleral tattooing.

Contact Lens Health Week

27 Contacts Lenses Found in Eye of 67 year old Woman

Contact Lens mass

A 67-year-old woman scheduled, for what was supposed to be a routine cataract surgery, underwent a foreign body extraction procedure instead. A staggering 27 contact lenses were removed from the eye of a woman who had worn monthly disposable contact lenses for over 35 years. As reported in the British Medical Journal last month, the ophthalmologist removed a large mass of 17 fused contact lenses. Upon further inspection under a microscope, an additional 10 contact lenses were retained. Although the patient had poor vision, she did not complain of any issues with her eye prior to the day of surgery.

“This case study underscores the importance of appropriately wearing and caring for your contact lenses. Disposable contact lenses are meant to be disposed of as reuse puts patients at high risk of serious eye infections, and in some cases permanent vision loss,” says Charles Flowers, MD, Associate Professor of Clinical Ophthalmology.

Those who wear contact lenses are at risk of infections of the ocular surface, due to low oxygen levels to the cornea (outermost part of the eye) or if the lenses have not been appropriately cleaned allowing build-up of infective agents.

In honor of Contact Lens Health Week here are some tips to preventing Eye infections

  • Wash your hands thoroughly before touching your eyes or face
  • Thoroughly clean your contact lenses, store in clean containers, and use fresh solutions without sharing
  • Change your contact lens case every three months. Do not use the same case beyond three months.
  • Do not share your makeup, face towels, or any eye drops
  • Wear protective eyewear outdoors or in a workplace where there may be hazards
  • Seek medical attention immediately if you notice symptoms of a suspected eye infection
  • Always use protection to prevent sexually transmitted diseases. Such diseases, although rare, can manifest in the eye

Thus routine eye exams are essential to ensure healthy vision. To schedule a consultation at our Los Angeles, Beverly Hills, Pasadena, or Arcadia location call 323-442-6335.


Helpful Tips for the Upcoming Solar Eclipse


What is a solar eclipse, and how does it affect my eyes?

A Solar eclipse occurs when the moon blocks the sun. On Monday August 21st, 2017, North America will experience a solar eclipse that will last about 2.5 hours. Although a small part of USA will experience a total eclipse in which the moon completely blocks the sun, for most places, including the Los Angeles area, it will be partial.

Directly looking at the solar eclipse is as harmful as sun gazing on a regular day. This causes damage in the retina, the light sensitive membrane in the back of the eye, and can result in vision loss – the severity of which depends on the duration of the gaze. In mild cases, the vision loss may be reversible over the course of several months, but in severe cases, it is permanent. It affects the central vision, and affected individuals may not be able to read or see faces; however, it does not affect the peripheral vision.

Here are some very important tips to prevent vision loss while enjoying watching the solar eclipse:

  1. Never look at the sun or solar eclipse without eye protection: use solar eclipse glasses (eclipse viewers) that have been approved by the American Astronomical Society. In those areas of the country where total eclipse occurs, it is safe to remove the eclipse glasses at the time of total eclipse, which may last a maximum of about 2.5 minutes.

  2. Sunglasses, no matter how dark, are not protective.

  3. Do not use eclipse glasses that are damaged or have a scratch on them.

  4. If using a binocular, camera or telescope, wearing eclipse glasses do not protect your eyes; the front lens of these devices that face the sun should be shielded with specially designed filters.

5 Reasons Why Your Child Should Get a Regular Eye Exam

NEWNEWEye Children

Future of Pediatric Eye Care – Suggestions on a physician’s guide

  • A child should have at least one comprehensive eye exam by age three.
  • Children should be regularly monitored for behavior that signals difficulty in seeing.

Have you ever seen your child squint when trying to read, move closer to the television or bring objects closer to help them see? As a parent, your automatic instinct may be that your child needs eyeglasses. However, sometimes the signs are not always obvious, and you may not realize that your child could be visually impaired.

Here are 5 reasons why your child should get a regular eye exam:

  1. Inability to see well can affect your child’s ability to read.
    • Researchers discovered children ages 4 and 5 with uncorrected farsightedness (hyperopia-the inability to see objects up close) performed poorly on literacy tests relative to those with normal vision. The results were reported in an NEI-funded study, Vision in Preschoolers-Hyperopia in Preschoolers (VIP-HIP), which conducted a literacy test on 492 preschool-age children to determine reading skills.
  2. Uncorrected refracted error (difficulty seeing far objects or close) is the cause of visual impairment (VI) for most children.
    • A simple check by a vision specialist could help children who experience vision problems by prescribing eyeglasses.
  3. Increasing numbers of children are experiencing vision problems.
    • It was reported that greater than 174,000 three-to-five year olds had VI in 2015. In 2060, a 26 % increase (greater than 220,000 children) in VI is projected.
  4. USC researchers found that VI among multiracial American children between 2015 and 2060 is projected to increase by 137%.
    • 44% VI cases are among Hispanic children by 2060
    • 22% VI cases are among African American children by 2060

  5. The Incidence of childhood myopia (inability to see objects at a distance) among American children has more than doubled over the last 50 years.
    • As reported in the largest study of childhood eye diseases ever undertaken in the U.S. MEPEDS (Multi-ethnic pediatric eye disease study), prevalence of myopia is highest in African-American children as compared to Asian and Hispanic children. Rohit Varma, MD, MPH, principal investigator of the Multi-Ethnic Pediatric Eye Disease (MEPEDS) study and director of the USC Roski Eye Institute, and Dean of the Keck School of Medicine of USC has brought together a team of world experts to study the array of vision disorders among preschool children. Such comprehensive studies help develop evidence-based guidelines to screen children for common pediatric vision disorders.

“In the Know” on Men’s Vision

Men's Health Banner

Historically men are less likely than women to go to the doctor and address any health concerns. This month take the time to learn more about how you can maintain healthy vision. When you see an ophthalmologist you will likely be screened for diseases such as glaucoma, age-related macular degeneration and cataracts. Routine vision screenings are essential to maintaining healthy vision, preventing permanent vision loss and even detecting diseases beyond the eye.

3 Systemic Diseases that Manifest in the Eye

Even if you have great vision, seeing a specialist can save your vision and even your life.

#1 Diabetes

Men are at higher risk of developing Type II Diabetes

Changes to retinal blood vessels found in the light sensing tissue in the back of the eye known as the retina, can be early symptoms of diabetes. Detection of bleeding or leaking of these blood vessels can lead to early diagnosis of diabetes which is known to cause a number of eye complications that include conditions such as diabetic retinopathy, diabetic macular edema (DME), cataracts and glaucoma. If left untreated, many have lost their vision and have even gone blind from this disease. Early detection of diabetes within the eye cannot only prevent vision loss, but a multitude of broader diabetic-related complications such as nerve damage, heart disease and even stroke.

#2 Hypertension

High blood pressure can increase with age but can even occur in men younger then 45

Hypertension or high blood pressure can cause damage to the blood vessels in your eye and can lead to hypertensive retinopathy. Over time, if high blood pressure is poorly controlled, major vision loss can occur due to damage to retinal blood vessels and even increase your risk for glaucoma. Associate Professor of Clinical Ophthalmology and Retina specialist, Andrew Moshfeghi MD, MBA, recommends regular eye exams. “Earlier detection of hypertensive retinopathy can alert your physician to the possibility of broader complications of hypertension including heart disease and stroke,” says Moshfeghi.

#3 Cancer

Metastases of lung cancer in and around the eye is more common in men

Breast and lung cancers are the most common primary malignancies that can metastasize to the eye and surrounding tissues. A study recently reported that in multiple cases, detection of eye metastases is often the first indicator of an underlying malignancy. Most notably for men, although relatively rare, prostate cancer can also metastasize to the eye. Regular ophthalmic exams for men in addition to routine physicals, which include prostate exams, are essential, as early detection will lead to better outcomes.

Thus routine eye exams can provide valuable information about your overall health. To schedule a consultation at our Los Angeles, Beverly Hills, Pasadena, or Arcadia location call 323-442-6335.

The Srikiran Eye Institute (SEI) resident experience is a rich one, not only in terms of surgical SICS training, but also clinically and culturally.

Regarding the day to day clinical and surgical exposure, your mentor for the time is Dr. Avinash, the medical director of SEI. Initially, residents will receive a brief tour of the compound, which will become very familiar after just a couple of days. At the time of this writing, SEI has comprehensive ophthalmology, in addition to the subspecialties of pediatrics and strabismus, oculoplastics, cornea/anterior segment, and retina/uveitis. Residents can spend time in whichever clinic they feel would best suit their interests. Expect to see many things that you’ve only read about in the textbooks here! Please note that the work week is from Monday to Saturday, with both clinic and OR M-F, and clinics alone on Saturday.

A major component of this rotation is the ability to learn small incision cataract surgery, an incredibly elegant surgery with fantastic results. Expect a small trickle of cases on a daily basis, with a large influx of patients after camp outreach days. Dr. Avinash (or designated surgeon) will initially show a few cases of SICS. The first cases will be proctored every step of the way, with more independence as the resident becomes more familiar with the operation.

Expect to busy during this block of time. Residents will be seeing patients in clinic and operating M-F, and seeing patients in clinic on Saturday. If you have a free Sunday, take a moment to explore Kakinada city (approximately 10km away) and the Bay of Bengal (approximately 3km away). If you have a day where clinic is not as busy, consider taking a moment to visit the schools located on the campus. The Sankurathri foundation not only oversees the Srikiran Eye Institute, but there is also a school system (from elementary to high school, and also vocational school).
