Rhegmatogenous retinal detachment (RRD) is frequently associated with reduced IOP thought to be from a decrease in aqueous production or an increase in aqueous outflow. In long-standing RRDs, photoreceptor outer segments may be released in sufficient quantities to obstruct aqueous outflow at the trabecular meshwork causing elevation of IOP. Retina reattachment surgery can normalize the high IOP.
Treatment goals should focus on repair of the retinal detachment and expeditious IOP control
Prognosis and Future Directions
After successful retinal detachment repair, the anterior chamber cellular debris often disappears and IOP tends to normalize
Visual potential often depends on early diagnosis and treatment. Glaucoma may be so prominent that the underlying treatable cause of retinal detachment may be overlooked.
