Detection of macular photocoagulation scars with confocal infrared reflection imaging.

Background And Objective: To study the diagnostic reliability (specificity and sensitivity) of confocal infrared reflection in detecting threshold argon laser photocoagulation scars in the macula.

Patients And Methods: Fifty-six maculae with diabetic macular edema were evaluated by biomicroscopic slit-lamp fundus examination, digital color fundus photography, digital fundus fluorescein angiography, and digital infrared reflection images. Three examiners evaluated whether the eye had undergone any laser photopexy in the macula.
