Central retinal vein occlusion with concurrent paracentral acute middle maculopathy secondary to honeybee sting

Abstract

We report the case of a 45-year-old male who presented with complaints of sudden decreased vision in the right eye (RE) associated with redness and lid swelling. He gave a history of honeybee stings 1 week ago to the right periorbital area. On examination, the patient’s best-corrected visual acuity in RE was 4/60. The anterior segment examination was normal. However, fundus examination and imaging revealed central retinal vein occlusion (CRVO) with paracentral acute middle maculopathy (PAMM) and macular edema. The patient’s routine blood tests were negative for any abnormalities that could have caused the vascular occlusion. The patient was prescribed topical steroids and advised to receive an intravitreal injection of ranibizumab. However, 2 weeks later, the patient returned with improved visual acuity and resolution of macular edema. His transient hypercoagulable state could have been the cause of his ocular symptoms. Few cases of central retinal artery occlusion (CRAO) secondary to bee venom have been reported, but none with CRVO and associated PAMM.
