Bee stings are a rare form of ocular trauma with the ocular sequelae attributable to the mechanical effects of the stinger as well as the inflammatory and neurotoxic effects of the venom. This research reports on a case of a retained corneal bee stinger and the technique used for removal of the stinger. This case report is of a patient that presented with a retained corneal bee stinger to St John Eye Hospital, Soweto. A 45-year-old male presented with a retained bee sting in the anterior chamber angle of the eye. A combination ab-externo technique was used to remove the sting. We present the case of a honey bee sting to the cornea that was removed using an ab-externo technique to maintain globe integrity and preserve vision.

The hazy corneal donor-recipient interface after corneal transplant may cause difficulties when implanting the XEN gel stent via ab-interno approach. We aim to describe XEN gel stent implantation via ab-externo approach in refractory steroid-induced glaucoma after corneal lamellar keratoplasty. Under local anaesthesia, the XEN injector needle was inserted 7 mm behind the limbus with the bevel facing up, directly beneath the conjunctiva and advanced to the marked 2.5 mm scleral entry wound. The needle then pierced the sclera until the needle tip was just visible in the anterior chamber (AC). The slider was pushed until the tip of the XEN stent was seen in the AC. The needle was slowly withdrawn while still pushing the slider to complete stent deployment. Subconjunctival Mitomycin C 0.01% (30 µg/0.3 mL) was then injected posterior to the bleb. Three eyes of three patients with steroid-induced glaucoma after lamellar keratoplasty underwent XEN gel stent implantation via ab-externo approach placed at the superotemporal quadrant. Pre-operatively, all patients had uncontrolled IOP between 30-45 mmHg despite maximum medications and selective laser trabeculoplasty. After XEN gel stent implantation, IOP ranged between 10-17 mmHg with one or two topical antiglaucoma at 12 months. Complications include hypotony maculopathy, stent migration and hyphaema, all of which were successfully managed. Corneal graft remained clear at 12 months. XEN gel stent implantation via ab-externo approach is able to achieve good intraocular pressure (IOP) control without compromising cornea graft in patients with steroid-induced glaucoma after lamellar keratoplasty at 12 months., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Tan et al.)
