Background: Occult choroidal neovascularisation (CNV) was treated by a novel surgical approach. In order to spare the retina during laser photocoagulation of occult CNV, the retina was detached by subretinal infusion of a finger solution. After localised detachment of the neural retina the CNV was transretinally coagulated by an endoprobe of a diode laser. Methods: Twelve patients with occult CNV were treated in such a way. The mean duration of follow-up was 3.5 +/-1.6 months. After 4 weeks fluorescein angiography and indocyanine green angiography were performed in all patients. Laser exposure time was 1.1 +/-0.7 s and laser energy was 1.2 +/-0.7 W. Results: In 10 of 12 patients the retina could be successfully detached and performed. In all cases the retina remained unchanged during laser photocoagulation. After 5 days subtle RPE atrophy and after I month obvious RPE atrophy was found. After 4 weeks, in 8 of 10 cases the CNV was completely occluded and no late leakage was found. Three months after operation, retinal atrophy could be seen in all cases. Visual acuity was lower in 6 and unchanged in 4 of 10 patients. Conclusion: Despite acute sparing of the neural retina the long-term effects are not better than after conventional laser photocoagulation, because secondary atrophy of the retina develops.
