Aims
Intravitreal steroid implants have emerged as an adjunctive therapy in diabetic macular edema (DME) in patients refractory to anti-vascular endothelial growth factor agents. However, the use of these agents in patients with a prior history of steroid-induced ocular hypertension is limited. The present study aimed to analyze long-term intraocular pressure (IOP) response to the dexamethasone implant in patients with DME and a history of steroid-induced increase in IOP.
Methods
In a multicenter retrospective review, 17 eyes with DME and a history of steroid-induced increase in IOP to > 21 mmHg were treated with the dexamethasone implant and followed for 18 months. Patients with a history of vitrectomy of vitreoretinal interface pathology were excluded. The primary outcomes were the change in IOP and use of IOP-lowering agents.
Results
Among the study population (17 eyes), there was no significant change in mean IOP from baseline through 18 months (15.9 ± 2.0–14.6 ± 2.8 mmHg; p = 0.18). The number of patients requiring IOP-lowering agents rose from 5 at baseline to 14 at 18 months (p = 0.0049). None of the study eyes required surgical treatment.
Conclusions
Though dexamethasone does predictably lead to an increase in IOP, this adverse effect was effectively managed with topical treatment. The present study suggests that the intravitreal dexamethasone implant may be considered in patients with DME and a history of steroid-induced ocular hypertension who have exhausted first-line treatments.
