Abstract

PURPOSE: To evaluate the efficacy of adjuvant topical dorzolamide-timolol in patients with neovascular age-related macular degeneration unresponsive to anti-vascular endothelial growth factor therapy. METHODS: This retrospective, interventional study included 15 patients with neovascular age-related macular degeneration refractory to anti-vascular endothelial growth factor. Patients used topical dorzolamide-timolol twice daily in the neovascular age-related macular degeneration eye and received anti-vascular endothelial growth factor therapy at each visit, with the same fixed interval and agent as before the addition of dorzolamide-timolol. Central macular thickness, maximal subretinal fluid height, and maximal pigment epithelial detachment height were measured at baseline and every visit. RESULTS: The mean follow-up period was 17.2 ± 5.5 weeks. The mean central macular thickness decreased from 383.5 μm at baseline to 298.3 μm at the final visit (P = 0.041). The mean maximal subretinal fluid height decreased from 105.0 μm at baseline to 58.3 μm at the final visit (P = 0.021). Complete resolution of subretinal fluid was observed in 3 of 11 subretinal fluid-type eyes. There was no significant change in the maximal pigment epithelial detachment height. The mean logarithm of the minimum angle of resolution visual acuity decreased from 0.61 (20/81 Snellen) at baseline to 0.66 (20/91 Snellen) at final visit, which was not significant (P = 0.314). The mean intraocular pressure decreased significantly from 14.9 mmHg at baseline to 12.3 mmHg at the final visit (P = 0.005). CONCLUSION: The use of adjuvant topical dorzolamide-timolol was effective in decreasing central macular thickness and subretinal fluid in patients with neovascular age-related macular degeneration refractory to continual fixed-interval intravitreal anti-vascular endothelial growth factor therapy, but did not result in functional improvement in this short-term study.
