PURPOSE: To report a case of branch retinal vein occlusion (BRVO) in which rapid formation of macular pucker was observed after an intravitreal ranibizumab (IVR) injection.
OBSERVATIONS: A 66-year-old patient was referred to our department for the treatment of macular edema (ME) secondary to BRVO in the left eye. On the initial visit, widespread retinal hemorrhage was observed around the superior temporal vascular arcade, and the decimal best-corrected visual acuity (BCVA) was 0.7 (Snellen equivalent 20/29) in the left eye. Optical coherence tomography demonstrated a thin epiretinal membrane (ERM) accompanied by diffuse retinal thickening. A 0.5 mg IVR injection was administered for the treatment of ME and prompt resolution of retinal hemorrhage. Fourteen days after IVR administration, the ERM had progressed remarkably into a macular pucker and had spread from the superior macula to the equator, accompanied by partial tractional retinal detachment. We performed pars plana vitrectomy combined with encircling scleral buckling. Three months after the surgery, the decimal BCVA was 0.4 (Snellen equivalent 20/50), the retina was attached, and no recurrence of ME or proliferation was observed.
CONCLUSIONS AND IMPORTANCE: IVR for BRVO may cause rapid formation of macular pucker in the eye, especially in the presence of pre-existing ERM. Careful observation of patients with BRVO is essential after administration of anti-VEGF agents, especially in eyes with pre-existing ERM.
