FORT LAUDERDALE, Fla. — The majority of proliferative diabetic retinopathy eyes that underwent treatment with the PASCAL photocoagulator showed a high success rate at a mean of 3.9 sessions with complete regression of new vessels, study authors said here.

"The study confirms the fact that [by] reducing the exposure time and increasing the power of conventional laser machines, [panretinal photocoagulation] in [proliferative diabetic retinopathy] is safe and effective and can be achieved with a more comfortable experience [to] the patient," Francesco Bandello, MD, FEBO, and colleagues said in a poster presentation at the Association for Research in Vision and Ophthalmology meeting.

They conducted a retrospective review of 26 eyes of 21 patients who had naïve severe nonproliferative diabetic retinopathy (seven eyes), early proliferative diabetic retinopathy (16 eyes) or high-risk proliferative diabetic retinopathy (three eyes).

A total of 19 eyes (73%) had complete regression of new vessels. In seven eyes, neovascularization was not completely resolved, needing additional photocoagulation, the study authors said.

One eye had a choroidal detachment that resolved in a week.
