The participants were aged 1 to 10 y with a mean age of 3.50±1.79 y. The mean follow-up time were 11.9 mo. Subretinal fluid was drained transsclerally using a novel method of DTV. The height of the retinal detachment and the regression of abnormal vessels including telangiectasias and aneurysms were observed. Complications including vitreoretinal fibrosis, tractional retinal detachments(TRD), endophthalmitis, retinal holes, and hemorrhages were evaluated.RESULTS: Following surgeries, the patients showed the replacement of ERD and regression of telangiectatic retinal vessels observed with binocular indirect ophthalmoscopy. Six patients received retinal cryotherapies and 12 patients received laser photocoagulations following first external subretinal fluid drainage using DTV. All patients underwent intravitreal anti-vascular endothelial growth factor therapies to induce residual subretinal fluid absorption. During followups, 8 patients underwent a second drainage operation, 17 patients received retinal laser photocoagulations and 7 patients received cryotherapies. Vitreoretinal fibrosis was found in 7 patients and 6 patients underwent microinvasive vitrectomies during the follow-up period. Severe TRD, iatrogenic retinal holes, and hemorrhages were not found.CONCLUSION: The authors present a new therapeutic approach that successfully drains subretinal fluid in advanced stage 3 B Coats disease with severe ERD.
