External drainage of subretinal fluid with or without scleral buckling in conjunction with xenon photocoagulation has been used to treat diffuse choroidal hemangiomas associated with large, exudative retinal detachments in SWS.

Pars plana vitrectomy, endolaser, and internal drainage of subretinal fluid can be performed. Cryotherapy and penetrating diathermy are of limited use because of the posterior location of the tumor.
