The effect of travoprost on subfoveal choroidal thickness in primary open angle glaucoma

Toassess the effect of topical travoprost on subfoveal Choroidal Thickness in Primary open glaucoma patients. The choroidal thickness, a sign of ocular blood flow can be altered by prostaglandin analogues. Hence this study was done to analyse the choroidal thickness after travoprost therapy. : This Prospective, interventional study included 41 eyes of treatment naive POAG patients. Subfoveal choroidal thickness was measured at first visit and after 3 months of topical travoprost therapy by Enhanced Depth Imaging Optical Coherence Tomography (EDI-OCT). The measurements were compared before starting the treatment and after 3 months of treatment with travoprost therapy. The mean choroidal thickness pre-treatment was 296.73 ± 28.07 mm post treatment was 311.56 ± 33.38 µm. The mean difference in choroidal thickness between pre-treatment and post-treatment was found to be 14.8 ±15.1 µm with median value(IQR) of 8 (3 - 30) µm (p-value< 0.00) which was statistically significant. Thecurrent study showed that Subfoveal choroidal thickness(SFCT) changes with travoprost therapy.
