ABSTRACT
A 32-year-old lady, diagnosed with anaplastic large cell non-Hodgkin's lymphoma of the mediastinum, presented with bilateral floaters and reduced right eye vision 3 years post chemotherapy. Ophthalmic examination revealed bilateral panuveitis with multiple deep seated choroidal lesions in the left eye. Computed tomography scanning of the orbit showed enhancing and bulky optic nerve sheath at the retrobulbar part of both optic nerves. The patient was treated with involved field radiation therapy of the orbit, with cumulative dose of 30Gy. Eight months post radiation therapy, she developed retinal pigment epithelial detachment at the macula and deep chorioretinal degeneration at superotemporal and inferonasal regions of the right fundus. There was evidence of vitreoretinal traction at the margin of chorioretinal degeneration areas, thus barricade lasers were performed in the affected eye. Her visual acuity remains 6/6 in both eyes. Retinal pigment epithelial detachment is a possible complication of radiation therapy in non-Hodgkin's lymphoma with intraocular metastasis. It is essential to alert the managing ophthalmologists about this rare complication.
ABSTRACT
·A 27-year-old man was stung by a bee presented with severe pain in the right eye. It was associated with reduced vision and swelling of the eyelids. A retained stinger was identified at the center of the cornea, surrounded by dense corneal oedema and numerous folds in the Descemet's membrane. The sting was removed completely. He subsequently developed persistent corneal oedema and heterochromia iridis. He was treated with intensive topical steroids. He underwent penetrating keratoplasty five months after the injury. His visual acuity was satisfactory one year after the surgery. Corneal oedema is an uncommon complication of bee sting injuries. It can be persistent and results in severe visual impairment. An early penetrating keratoplasty offers a good visual outcome after bee sting injury.
