To assess the microperimetry changes on normal human retina of retinal photocoagulation lesions of various clinical grades.
A 532-nm diode laser was used to irradiate the temporal retina of 20 patients undergoing photocoagulation for proliferative diabetic retinopathy and the resulting lesions immediately graded according to its clinical appearance from an invisible or mild gray to a moderate to severe white. Microperimetry was performed at the targeted area prior and at 1 and 4-week post laser irradiation.
Showing a parallel pattern of response for all patients involved in this investigation, invisible and light to light-moderated burns caused no detectable changes on the microperimetry assessment. On the contrary, moderate to intense lesions caused a sustained significant decrease in retina sensitivity.
