Intraocular pressure fluctuation following intravitreal dexamethasone implant and incidence of secondary ocular hypertension: a Zambian perspective.

Introduction: to evaluate the effect of dexamethasone biodegradable implant (DEX-I), on intraocular pressure (IOP), to determine the incidence of secondary ocular hypertension (OHT) and to analyze the IOP changes as per the treatment indication in Zambian cohort.

Methods: retrospective consecutive case series of patients receiving one DEX-I between January 2016 and September 2018 with a minimum follow-up of four months in a tertiary care centre in Zambia. The IOP was recorded before the injection and at 1 week, 1, 2, 3 and 4 month after the injection.
