VEGFA and glaucoma: To prevent immediate postoperative elevation of IOP in glaucoma patients, the French Glaucoma Society suggests the instillation of 1% apraclonidine or dorzolamide/timolol a few hours before anti-VEGF injection [66], while prophylactic administration of acetazolamide 60–90 min before intravitreal ranibizumab injection showed a statistically significant but modest reduction in IOP after 30 min [67].
