RESUMEN
PURPOSE: To report a case of severe ocular graft-versus-host disease (GVHD) after cataract surgery. METHODS: Observational case report. RESULTS: We describe the case of a 59-year-old man with postoperative corneal ulcer on his only functional eye. His past history reported allogenic bone marrow transplant. His visual acuity (VA) was limited to hand motions. Slit lamp examination revealed diffuse conjunctival hyperemia, severe blepharitis, Meibomian dysfunction, total corneal opacification with epithelial and stromal keratitis and neovascular invasion. Because of the severe dry eye symptoms and history of allogenic hematological stem cell transplantation, ocular GVHD was diagnosed. Functional and anatomical improvement occurred rapidly with topical cyclosporine 2%, with improved VA after treatment. CONCLUSION: With any severe dry eye syndrome in the context of allogenic bone marrow transplant, ocular GVHD must be considered. For planned ocular surgery, we recommend adding cyclosporine 0.1% treatment before and after surgery to prevent severe ocular GVHD.

INTRODUCTION: The intravitreal dexamethasone implant has shown efficacy in the treatment of macular edema (ME) arising after retinal venous occlusions (central or branch), and in the treatment of non-infectious uveitis. The purpose of this study was to evaluate the efficacy of this implant in the treatment of other diffuse macular edemas with an inflammatory mechanism. MATERIALS AND METHODS: We carried out a retrospective cohort study over 2 years: from January 2012 to December 2013, including all patients who received at least one injection of intravitreal dexamethasone implant, excluding venous occlusions and non-infectious uveitis. The primary study parameter was the progression of visual acuity. The study protocol had the approval of the institutional review board of the respective clinical ethics committees, and was conducted in accordance to the tenets of the Declaration of Helsinki. RESULTS: Eighty patients were included. Eighty-eight percent of patients were pseudophakic. The indications for treatment were: diabetic ME when anti-VEGF were ineffective (53%), ME after retinal detachment (RD) (22%), ME of Irvine-Gass syndrome (16%), ME after endophthalmitis (4%), macular telangiectasia (4%), ME secondary to retinitis pigmentosa (1%). The mean ETDRS visual acuity was 53.7 letters prior to injection, improving to 62.3 letters after injection (P<0.001). The average gain in visual acuity was 6.7 letters [4.53;8.84] (P<0.001) in patients treated for diabetic ME, 9.6 letters [6.1;13.1] (P<0.001) in patients with ME after RD, and 15.2 letters [10.25;20.28] (P<0.001) for Irvine-Gass syndrome. The mean duration of efficiency was 4.6 months, with a median of 3.8 months. CONCLUSION: The intravitreal dexamethasone implant appears to be an effective second-line treatment even in patients with diabetic ME after failure or in the case of contraindication of anti-VEGF. It is also effective and well tolerated in patients with ME after RD, as well as in patients with Irvine-Gass syndrome.
