NCT02995629 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 40

Last updated 2016-12-16

No results posted yet for this study

Summary

Our aim is to compare patient comfort when using the 532 nanometer (green) wavelength laser to the 577 nanometer (yellow) wavelength laser during pan retinal photocoagulation to treat patients with diabetic retinopathy. Secondary outcome measures will be power (mW) required to achieve gray-white retinal burns and duration of treatment.

Conditions

  • Proliferative Diabetic Retinopathy - High Risk

Interventions

PROCEDURE

laser indirect ophthalmoscopy pan retinal photocoagulation

* Prior to procedure, eligible patient is dilated and a topical anesthesia is administered 3 to 5 minutes prior to treatment initiation * Treatment duration is fixed at 50 minutes and power is titrated until moderate gray-white burns are achieved, avoiding long ciliary nerves * Target treatment of 250 spots * Only one eye per eligible patient randomized with regard to whether green or yellow laser utilized first * After treatment,pain assessment conducted:spot count, laser parameters and treatment duration recorded for each respective laser wavelength
