Purpose: To describe the characteristics of and associated risk factors for macular HE in patients with BVO. Methods: The records of 83 patients (85 eyes) with BVO were reviewed. All patients underwent a complete ophthalmic examination, including best-corrected visual acuity and contact lens slit lamp biomicroscopic ophthalmoscopy, and fluorescein angiography. Results: Macular HE developed in 27 eyes (31.8%). They were severe in 10 of 27 eyes (37%). Foveal location of HE was observed in 6 eyes (22.2%). The presence of HE was significantly (p< 0.05) associated with diabetes, retinal macroaneurysms, and severe capillary leakage on fluorescein angiography. Conclusions: In patients with BVO, particularly those at high risk for developing HE, close follow-up and timely focal laser treatment are crucial to prevent visual loss due to the accumulation of HE in the fovea.
