Abstract

In the present study, 110 eyes of 81 patients with uveitis who underwent intravitreal dexamethasone implant (IDI) injection and had a follow‑up of at least 6 months between January, 2012 and September, 2022, were retrospectively analyzed. A total of 298 IDI injections were administered (mean, 2.71±2.37; range, 1‑12). The mean age of the patients was 49.44±16.67 years (range, 15‑86 years). The mean follow‑up time after the first IDI was 34.31±26.53 months (range, 6‑115 months). In total, 77 (95.1%) patients had non‑infectious uveitis, while 4 patients (4.9%) received IDI for uveitic macular edema in association with infectious uveitis (1 patient with acute retinal necrosis and 3 patients with systemic tuberculosis). IDI was injected under the umbrella of intravitreal ganciclovir injection in the patient with healed acute retinal necrosis for the associated pseudophakic cystoid macular edema. A total of 6 patients (7.4%) received IDI prior to phacoemulsification surgery to control the possible post‑operative macular edema. In addition, 3 patients (3.7%) with Vogt‑Koyanagi‑Harada disease received bilateral IDI as the systemic therapy could not be administered due to side‑effects of the systemic treatment. In total, 1 patient (1.2%) with idiopathic retinal vasculitis, aneurysms and neuroretinitis was treated with IDI injections in both eyes in addition to systemic therapy to reduce the ongoing inflammation. Of note, two eyes (1.8%) received simultaneous single IDI and anti‑vascular endothelial growth factor administration for the treatment of unilateral extrafoveal macular neovascularization (one with active serpiginous choroiditis and one with sympathetic ophthalmia). IDI was administered for the treatment of uveitic macular edema in 68 patients (83.9%). Best‑corrected visual acuity improved from 0.69±0.64 to 0.60±0.76 logMAR at the final visit (P=0.008). Baseline mean central macular thickness (CMT) was 499.74±229.60 µm (range, 187‑1,187 µm) and the mean final CMT was 296.60±152.02 µm (range, 126‑848 µm). Intraocular pressure elevation requiring topical antiglaucomatous eye drops occurred in 28 eyes (25.5%). During the follow‑up period, bilateral glaucoma surgery was required in 1 patient (1.2%) and 25 of 65 phakic eyes (38.4%) underwent phacoemulsification. Retinal detachment occurred in one eye (0.9%), endophthalmitis in one eye (0.9%), and transient intravitreal hemorrhage occurred in three eyes (2.7%) after the IDI injections. On the whole, the present study demonstrates that although IDI is mostly employed in non‑infectious uveitic eyes with macular edema, it can also be administered in cases with systemic therapy intolerance, pseudophakic macular edema prophylaxis, and with great caution, in selected cases involving infectious uveitis and macular edema.
