[Choroidal lesions and surgical treatment of bullous retinal detachment].
To define choroidal lesions of bullous retinal detachment, we performed indocyanine green angiography (IA) on 20 eyes of 10 patients with bullous retinal detachment. Four of these eyes were treated with sclerectomy and sclerostomy (Gass), and the benefit was evaluated. IA showed the following choroidal abnormalities: choroidal filling delay in the macular region (6 of 18 eyes, 33%) and underneath the leaking sites (9 of 18 eyes, 50%), localized (1 eye, 5%) and extended (18 eyes, 90%) choroidal venous dilatation, and intrachoroidal hyperfluorescence (all eyes, 100%). After the surgical treatment, retinal detachments resolved within 9 weeks (mean 5.3 weeks). Since choroidal filling delay, choroidal venous dilatation and intrachoroidal hyperfluorescence were observed, it is suggested that choroidal congestion plays a causative role in bullous retinal detachment. Sclerectomy and sclerostomy seemed to be beneficial in treatment of this condition.
