PURPOSE: To study the efficacy of intravitreal bevacizumab on a pro re nata basis for treatment of idiopathic choroidal neovascular membrane. MATERIAL AND METHODS: Thirty-seven eyes of 37 patients presenting with idiopathic choroidal neovascular membrane were included in the study. Intravitreal bevacizumab (1.25 mg/0.05 ml) was given on a pro re nata basis from the base line. RESULTS: Twenty-one (58.3%) patients were male and 15 (41.7%) were female aged 13-49 years. Idiopathic choroidal neovascular membrane showed a classic leak on fluorescein angiogram in all the eyes. Subfoveal location (25; 67.6%) was the commonest site of involvement. Mean number of intravitreal bevacizumab injections required to achieve resolution was 2.81 ± 1.4. At final follow-up, 31 (83.8%) eyes had maintained or improved vision (Group A) and six (16.2%) eyes had worsening of vision (Group B). There was no significant difference in mean age, gender, and mean number of injections between groups A and B. CONCLUSION: Intravitreal bevacizumab on a pro re nata basis is effective in the treatment of idiopathic choroidal neovascular membrane. A larger controlled study would be required to formulate an accurate injection protocol.
