To introduce the concept of targeted retinal photocoagulation (TRP) using retinal navigation (eye-tracking).
Tertiary care/academic center
In this interventional case series study were included the eyes in need of TRP. Six eyes with proliferative diabetic retinopathy (PDR) had prior panretinal photocoagulation (PRP) and showed residual leakage on fluorescein angiography; one eye with PDR and three eyes with severe non-proliferative retinopathy were treatment naïve eyes. Main outcome measures were safety and feasibility of the new approach.
Ten eyes of 8 patients with diabetic retinopathy were treated using navigated TRP. There was no inadvertent photocoagulation of the vital structures such as the fovea, optic nerve or retinal vessels, and all laser applications in all eyes hit the preplanned points. There was only one treatment session for all patients/per eye. The patients tolerated the procedure well and the visual acuity in all eyes was the same as at the baseline. On follow-up examination the laser applications were visible in the areas targeted for treatment.
Navigated TRP is a new way to perform TRP and offers several advantages to conventional TRP which uses slit-lamp or indirect ophthalmoscope laser delivery. It can be applied in numerous retinal conditions where selective laser photocoagulation is treatment goal. It is a safe and feasible technique, clinical efficacy of which needs to be tested.
