Purpose: To report complications requiring surgical management related to intravitreal dexamethasone implant.
Methods: The medical records of patients who received intravitreal dexamethasone implant injection from June 2013 to March 2020 were reviewed retrospectively. Patients who had undergone intraocular surgical management within 6 months after implant injection, with the exception of cataract surgery, were included. Of them, only the cases in which the surgery was definitely related to complications with the Ozurdex implant were included. In these patients, underlying disease, intraocular pressure change, and the number of injections were analyzed.
Results: A total of 1,168 injections of 473 eyes (439 patients) were enrolled in the study. The mean number of injections was 2.5 per eye. The mean age was 61.4 ± 11.3 years. The complications requiring an additional surgical procedure occurred in six (0.5%) injections. Of them, four, one, and one eyes showed uveitis, diabetic macular edema, and branch retinal vein occlusion, respectively. Surgical management was performed to control the increased intraocular pressure in two eyes, inappropriate implant location in two eyes, scleral wound leakage in one eye, and retinal detachment in one eye. The incidence of severe complications requiring surgical management was high in cases with a history of previous vitrectomy (p = 0.007, Fisher’s exact test) and uveitis (p = 0.007, Fisher’s exact test).
Conclusions: Severe complications requiring surgical management occurred in 0.5% of cases (six cases) after intravitreal dexamethasone implant injections. These complications were related to a history of previous vitrectomy and uveitis. Five eyes recovered to favorable visual function after surgery, with the exception of one eye with retinal detachment.
