Purpose: To report a noninvasive method for evaluating eyes with cystoid macular edema.
Methods: We obtained infrared images of cystoid macular edema in eight eyes of eight patients using a scanning laser ophthalmoscope with the dark-field mode of a 780-nm diode laser. Differences between infrared images and fluorescein angiograms in the imaging of cystoid changes were examined.
Results: With the scanning laser ophthalmoscope, we observed cystoid macular changes as images that resembled three-dimensional pictures in the dark-field mode with infrared light. Cystoid changes observed by this method generally agreed with changes observed by fluorescein angiography.
Conclusions: Scanning laser ophthalmoscopy with infrared light in a dark-field mode is noninvasive, and the results in eyes with cystoid macular edema generally agreed with results obtained by fluorescein angiography. This method is useful for examining eyes with cystoid macular edema.
