AbstractTo report on the characteristics and outcome of management of Coats' disease, and to describe a novel surgical technique for management of stage 3B with total retinal detachment (RD) by scleral external drainage with anterior chamber (AC-maintainer) placement before the drainage without pars plana vitrectomy.A retrospective study of 26 eyes from 25 Coats' patients. Outcome measures included: demographics, presentation, laterality, stage, treatment, and outcome.The median age at diagnosis was 3.5 years. Twenty patients (80%) were males, and all except 1 girl had unilateral disease. The presenting complaint was impaired vision in 13 (50%) eyes, leukocoria in 6 (23%) eyes, and strabismus in 7 (27%) eyes. Based on the Shields classification; 3(12%) eyes were stage 1, 9 (35%) eyes were stage 2, 10 (38%) eyes were stage 3, 2 (8%) eyes were stag e4, and 2 (8%) eyes were stage 5. Primary management included cryotherapy (54%), laser photocoagulation (27%), intravitreal anti-vascular endothelial growth factor (23%), intravitreal steroids (23%), and surgical drainage (12%). The 3 eyes in stage 3B (with total exudative RD) underwent subretinal fluid drainage with AC maintainer, and all had the retina reattached completely for 6 months follow up after the surgery. At mean follow up 21 months, 4 (15%) eyes were enucleated, 19 (73%) eyes had improvement or stabilization in visual acuity.Coats' disease usually presents at advanced stage with poor visual prognosis, individualized management with close follow up are mandatory to save the eye. Subretinal fluid drainage with AC maintainer is a safe and useful technique for repairing total RD in eyes with stage 3B Coats' disease.
