Patients with certain retinal degenerations will be asked to take part in a research study about the use of a topically applied eye drop for treating fluid in the central part of the retina (macular edema).
In the current study, investigators propose to use topical Trusopt in a group of patients with retinal degeneration (RD) to determine its effectiveness in reducing the amount of retinal fluid in patients with RD and macular edema. The methods will involve an initial one month treatment with topical Trusopt three times a day in each eye. After a period of one month, patients will return for a follow-up examination. At baseline, they will have had a measurement of their center vision and a measurement of their macular fluid with a photographic-like procedure termed optical coherence tomography (OCT). After the one month period of treatment, they will again have a measurement of their vision and re-evaluation with OCT. An improvement at least of one line (7 letters) or more of vision will be considered as a clinically significant improvement.
