Aim: To find out statistical data regarding intravitreal injections in an outpatient department setup at a tertiary center in Oman. Design: Retrospective chart review. Methods: Data collection of patients who underwent intravitreal injections from November 2009 to May 2013 at Sultan Qaboos University Hospital. Results: Throughout a period of 42 months, a total of 711 intravitreal injections were performed. That included 214 patients (275 eyes). Around one-third of the eyes received two injections or more. The injected agents were bevacizumab (59.8%), ranibizumab (32.3%), triamcinolone (7.5%), and very few patients with endophthalmitis received intravitreal antibiotics and antifungal agents. The three most common indications for the injection therapy were diabetic macular edema (50.9%), choroidal neovascularization (24.3%), and retinal vein occlusive diseases (11.5%). Serious adverse events were rare, and they occurred as ocular (0.9% per patient) and systemic (3.3% per patient). There were 42 eyes received intravitreal triamcinolone, and 24% of them developed intraocular hypertension that required only medical treatment. Conclusion: Different intravitreal agents are currently used to treat many ocular diseases. Currently, therapy with intravitreal agents is very popular, and it carries a promising outcome with more efficiency and safety.
