Abstract
In order to evaluate the Scanning Laser Ophthalmoscope as a method of assessing diabetic retinopathy, 57 consecutive patients with diabetes were examined through undilated pupils using laser ophthalmoscopy followed by pupillary dilatation and direct ophthalmoscopy. Results of laser scanning were recorded on videotape and analysed independently. Scanning (both eyes) took under 5 minutes per patient. For the 113 eyes studied, the two techniques gave concordant results in 73/113 (65%). Where there was discordance, laser ophthalmoscopic severity was greater than direct ophthalmoscopy in 36/40 (90% of discordant results). In 4/40 eyes conventional ophthalmoscopic appearances were judged more severe than those seen with the laser. The laser ophthalmoscope may have value as a method of assessing diabetic retinopathy, but further work is required to evaluate its efficacy as a screening tool in patients with moderate to severe retinopathy.
