Background: A chief morbidity of Graves eye disease is upper eyelid retraction that results in exposure keratopathy and cosmetic deformity. Objective: To assess the efficacy of graded anterior blepharotomy to treat upper eyelid retraction. Methods: Fifty eyelids of 32 patients with Graves eye disease-associated upper eyelid retraction, causing symptomatic ocular exposure, were treated with graded, transcutaneous, full-thickness, anterior blepharotomy. Preoperative and postoperative ocular exposure symptoms, upper eyelid position, lagophthalmos, and keratopathy were compared. Results: At a meanϮSD of 8.5Ϯ8.1 months' (range, 2-35 months) follow-up, more than 90% of preoperative symptoms resolved or improved. Upper eyelid position (PϽ.001), lagophthalmos (PϽ.001), and keratopathy (PϽ.01) were significantly improved. Mild contour abnormalities (all Յ1 mm) occurred in 7 of 50 eyelids. Eyelid crease recession or asymmetry occurred in 4 of 22 patients with postoperative eyelid crease measurements. Complications of ptosis, wound dehiscence, and a full-thickness hole each occurred once. The meanϮSD time taken to perform the procedure was 31.5Ϯ8.9 minutes per eyelid. Conclusions: Graded anterior blepharotomy for upper eyelid retraction is a safe and highly effective surgery for upper eyelid retraction associated with symptomatic Graves eye disease. This technique achieves excellent functional and cosmetic outcomes.
Background: We previously reported retinal toxic reactions in rabbit eyes receiving intravitreal injections of commercial tissue plasminogen activator (tPA) in concentrations greater than or equal to 50 µg/0.1 mL, and recent clinical experience suggests that intravitreal tPA solution may produce toxic effects in human eyes. We therefore investigated the dose-dependent retinal toxicity of intravitreal commercial recombinant tPA solution in cat eyes, which have a vascularized inner retina and vitreous volume similar to that of human eyes. Methods: Commercial tPA in L-arginine solution was injected into the mid vitreous cavity of normal cat eyes in doses of 25, 50, 75, and 100 µg/0.1 mL and 200 µg/0.2 mL. Control (fellow) eyes received an equal volume of sterile saline solution. After injection, eyes were evaluated by ophthalmoscopy and electroretinography for 14 days and then enucleated for histopathological evaluation. Results: Fundus pigmentary alterations were observed in eyes receiving doses greater than or equal to 50 µg/0.1 mL. Changes were centered in the area around the injection site, and the area's size increased in proportion to the dosage. Mean electroretinography B-wave amplitude measured at 14 days was significantly reduced in eyes receiving greater than or equal to 50 µg of tPA in a dose-dependent fashion. Light microscopy of the involved areas showed loss of photoreceptor elements with necrosis and proliferation of the retinal pigment epithelium. Conclusion: Intravitreal injection of commercial tPA solution results in dose-dependent retinal toxicity in cat eyes. Clinical Relevance: Because cat eyes are similar to human eyes regarding retinal vascularity and vitreous volume, intravitreal injections of commercial tPA (with L-arginine vehicle) in concentrations greater than 25 µg/0.1 mL are potentially unsafe in human eyes.
Purpose: To demonstrate the efficacy of local corticosteroid therapy for the treatment of eyelid and orbital xanthogranuloma in adults.Methods: We performed a retrospective chart review of six patients receiving local triamcinolone acetonide (40 mg/mL) injections for the treatment of eyelid and orbital xanthogranuloma at the University of Michigan. All patients underwent diagnostic biopsy prior to treatment. The effects of this therapy on symptoms and signs of the disease were assessed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
