          Abstract

          We report the case of a 54-year-old male who presented with complaints of decreased vision in the left eye (LE). He gave a history of multiple bee stings following which he had an episode of allergic anaphylaxis to the face and neck region for which he was admitted and treated with steroids. On examination, he was found to have LE central retinal artery occlusion (CRAO) which was the cause of his reduced vision. This is the first report of a bee sting venom as a cause for CRAO.

          Ocular manifestations of isolated corneal bee sting injury, management strategies, and clinical outcomes

          Purpose: The purpose of this study is to describe the presenting features, management strategies, and clinical outcome following bee sting injury to the cornea. Methods: Retrospective case series involving 11 eyes of 11 patients with corneal bee sting injuries who presented over a period of 2 years. Nine of these 11 eyes had the presence of intact bee stinger in the cornea, which was removed immediately under an operating microscope and sent for microbiological and histopathological evaluation. The patients were managed as per the individual treatment protocol of the respective treating physicians. Results: Six eyes (54.5%) had a good clinical outcome (best-corrected visual acuity [BCVA] >20/40) with medical therapy alone with no need for surgical intervention. Five eyes (45.5%) had a poor clinical outcome (BCVA <20/40) with medical therapy and required surgery; of which three required a combined penetrating keratoplasty with cataract surgery, while one required isolated cataract surgery and one underwent penetrating keratoplasty. Glaucoma was present in 3/5 eyes undergoing surgery, one of which required a trabeculectomy. Five of the six eyes who had a good clinical outcome with medical therapy alone had been treated with concomitant oral steroids, along with topical antibiotic-steroid combination therapy. Conclusion: Oral corticosteroid supplementation to the topical steroid antibiotic treatment in patients with corneal bee sting injury where corneal involvement and anterior reaction is severe at presentation or inflammation not ameliorating with topical steroids alone prevents serious vision-threatening complications such as corneal decompensation, cataract, and glaucoma.

            Myocardial infarction following a bee sting: A case report of Kounis syndrome

            In this case report study a 41-year-old man envenomed by a bee sting and diagnosed as Kounis syndrome secondary to hymenoptera envenomation. The patient developed a typical course of myocardial infarction, but the electrocardiogram changes were reversed to almost normal limits. He had a nonsignificant mild lesion in the proximal port of right coronary artery in coronary angiography. The case recovered and discharged after 6 days hospitalization. The clinical implications and pathophysiology of this dangerous association are discussed.

              Optic neuritis after bee sting.

              The purpose of this report is to document an unusual case of fully recovered vision after optic neuritis caused by bee sting. A 46-year-old man presented with sudden visual loss after being stung by a bee on the left conjunctiva. He developed optic disc swelling and there was a delay in the P100 wave of the pattern visual evoked potential (VEP). The patient received acute treatment, with intravenous methylprednisolone followed by oral prednisolone. Two days later, visual acuity in the left eye was recovered to 20/20 and P100 latency in pattern VEP was also normalized. Furthermore, visual field and color vision tests revealed no remaining abnormalities. This case suggests that early corticosteroid treatment is effective in optic neuritis caused by bee sting.
