Study: Laser flare measurement gives clues to diabetic retinal dysfunction

VIENNA — Laser flare measurement may be a useful tool for assessing diabetic dysfunction in the back of the eye, a study here indicated.
Kerstin Jandrasits and colleagues suggest that a correlation exists between the effect of grid photocoagulation on the blood-retina barrier and the permeability of the blood-aqueous barrier. Laser flare intensity “seems to be a quantitative indicator for the diabetic dysfunction of the blood-retina barrier,” they said.
The researchers performed modified grid pattern photocoagulation on 20 patients with diabetic macular edema. Aqueous flare intensity was measured by the laser flare cell meter before and 4 months after laser treatment. The mean flare value decreased from 9.8 photons/ms before treatment to 7.1 photons/ms after treatment.
The study is published in the January issue of Ophthalmologica.
