Official title
A Randomized Controlled Trial Comparing the Effect of Topical Dorzolamide-Timolol Versus Placebo Combined With Intravitreal Anti-Vascular Endothelial Growth Factor (VEGF) Injections in Patients With Neovascular Age-Related Macular Degeneration Who Are Incomplete Anti-VEGF Responders
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
A previous pilot study demonstrated that commonly available glaucoma drops (dorzolamide-timolol) might decrease the amount of chronic swelling in patient with wet age-related macular degeneration who have been receiving anti-vascular endothelial growth factor (VEGF) injections. This will be a larger study where subjects are randomly assigned to receive the glaucoma drops or a placebo (artificial tears) in order to confirm whether this previous finding is valid. Subjects will continue to receive the normally scheduled anti-VEGF injections at regular intervals as done prior to enrollment. The only addition to the regimen will be the daily use of eye drops (dorzolamide-timolol or artificial tears) twice daily for the duration of the study. At the end of the study, the swelling in the retina will be compared to the amount before starting the drops to see if there is any difference between the group using dorzolamide-timolol versus artificial tears.
