We observed 43 eyes by a scanning laser ophthal-moscope (SLO, Rodenstock), to detect retinal nerve fiber layer defect (RNFLD). The series com-prised diabetic retinopathy, glaucoma and ischemic optic neuropathy. We used monochromatic lights of helium-neon and argon lasers. The findings were compared with monochromatic photographs taken by conventional fundus camera. SLO led to the detection of RNFLD in 13 out of 17 confirmed eyes, or sensitivity of 77%. There were 2 instances offalse positive finding by SLO in 23 eyes without RNFLD, or specificity of 91%. There were further advantages by monochromatic fundus examination with SLO. It allowed observation through small pupil. Findings were obtained as real-time video images. The patients were comfortable during examinations as SLO required far less intense light for observation. Quality of fundus photograph by SLO was of lesser quality than that by fundus camera. Still, the present SLO system was satisfac-tory in detecting less pronounced RNFLD.
