Dr.N.Venkatesh Prajna and associates of Aravind Eye Hospital, Madurai, Tamil Nadu conducted a study is to describe the presenting features, management strategies, and clinical outcome following bee sting injury to the cornea.The study has been published in Indian Journal of Ophthalmology.
The study included 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.
It was found that 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.
The researchers therefor concluded that Oral corticosteroid supplementation to the topical steroid antibiotic treatment in patients with corneal bee sting injury where corneal involvement and the 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.
