Abstract
Purpose
To evaluate the potential efficacy and safety of primary intravitreal ranibizumab in patients with symptomatic retinal arterial macroaneurysm (RAM).
Methods
This prospective study comprised 5 eyes with RAM treated with intravitreal ranibizumab. At baseline, all patients underwent best-corrected visual acuity (BCVA) measurement, ophthalmic examination including slit-lamp biomicroscopy, and central foveal thickness (CFT) measurement using optical coherence tomography. Fluorescein angiography was also performed to confirm diagnosis. Patients were examined at 1 month after injection and monthly thereafter. Main outcome measures included changes in BCVA and CFT. Safety was assessed by ophthalmic examination and report of systemic adverse effects.
Results
There was a statistically significant difference in BCVA (p<0.001) and CFT (p<0.001) before and after the ranibizumab injection at the end of the follow-up of 13.4 ± 3.2 months. One injection appeared to be sufficient for the resolution of macular edema and absorption of hemorrhages. No observable ocular or systemic side effects were found. One patient developed foveal atrophy.
Conclusions
Intravitreal ranibizumab seems to be effective and safe for the treatment of symptomatic RAM.
