Title	Large spot size-transpupillary laser diode and adjuvant ICG for retinal hemangiomas
Abstract Nr.	1069

Purpose	To evaluate the efficacy, ocular and visual outcomes, and treatment complications of large spot-size transpupillary diode laser (TDL) with or without ICG
Methods	Prospective study including 17 retinal hemangiomas in 12 eyes (11 patients). TDL (810 nm) with large spot size-indirect ophthalmoscopy (1.2 mm) was directly applied to the lesion. Six tumors (35%) were treated by TDL alone and 11 (65%) by ICG-enhanced TDL. The ICG solution (25 mg/10 CC) was IV injected 1 minute before TDL. Von Hippel Lindau disease was diagnosed in 8 patients (73%)
Results	After a mean follow-up of 60 months (range, 6 to 191), 14 hemangiomas (82%) presented with a flat scar and 3 (18%) showed regressed fibrotic appearance. The mean tumor diameter was 2.3 mm (range, 0.5 to 8). Visual acuity improved in 5 eyes (42%), decreased in 4 eyes (33%) and was stable in 3 eyes (25%). Decreased visual acuity was related to the juxtapapillary location of the hemangioma (2 eyes) or partially regressed macular exudation (2 eyes). Epiretinal macular membrane was observed in 4 eyes (24%). No other complication was recorded. Macular and peripheral retinal exudation completely disappeared in 15 eyes (88%) and partially regressed in 2 (12%).
Conclusion	Large spot size-TLD appeared to be a safe therapeutic option for visual threatening exudative retinal hemangiomas. The only complication was epiretinal macular membrane. The potential benefit of ICG injection on tumor and /or exudation regression could not be statistically evaluated due to the small number of treated hemangiomas
