PURPOSE: To evaluate the characteristics and progression of patients treated with a 0.7mg dexamethasone intravitreal implant (Ozurdex) and required glaucoma filtering surgery (phaco-non-penetrating deep sclerectomy) to control ocular hypertension (OHT). METHODS: A retrospective observational study including patients treated with Ozurdex in a tertiary-care university hospital from May 2011 to April 2016. RESULTS: In five years of follow-up, 1.10% (4/363) of patients treated with 0.7mg dexamethasone intravitreal implant required phaco-non-penetrating deep sclerectomy (PNPDS) to control OHT refractory to topical treatment. All four patients started or increased previous antihypertensive topical treatment since the first dexamethasone intravitreal implant. Three or more dexamethasone intravitreal implants were injected in the four cases before intraocular pressure (IOP) became uncontrolled and PNPDS was performed. All four patients have a successfully controlled IOP without treatment after PNPDS. Two patients required additional treatment with dexamethasone intravitreal implants after PNPDS, maintaining IOP under control without treatment. CONCLUSIONS: To the best of our knowledge, this is the first study describing the successful results of PNPDS in OHT secondary to dexamethasone intravitreal implant. All four patients have achieved controlled IOP without treatment. Re-treatment with dexamethasone intravitreal implant in those patients who underwent PNPDS is also possible, and IOP remains controlled.
