PURPOSE: To compare 2-dimensional (2D) photo imaging with slit-lamp photo imaging for examination of trabeculectomy eyes, and to compare the accuracy and consistency of examination of trabeculectomy eyes with a remote operating slit-lamp microscope system (referred to as "remote slit lamp" hereafter) and a conventional slit-lamp microscope system (referred to as "slit lamp" hereafter). METHODS: Thirty-five eyes of 35 patients having a history of trabeculectomy were enrolled in the study that compared 2D photo imaging with slit-lamp photo imaging for the evaluation of trabeculectomy eyes. Five ophthalmologists evaluated the 2D images and the slit-lamp images independently with masking of patient information. Evaluation scores were compared with those provided by a glaucoma specialist using the slit lamp as standard. Fifteen eyes from 15 patients having a history of trabeculectomy were enrolled in the study that investigated the accuracy and consistency of examination of trabeculectomy eyes with a remote slit lamp and a slit lamp. RESULTS: Central anterior chamber depth, bleb height, and bleb extent evaluated by the slit-lamp photo imaging showed significantly higher consistency with the standard than those evaluated by 2D photo imaging (P<0.05). The remote slit lamp showed good consistency of all the evaluated parameters with the slit lamp and the κ scores of all the evaluated parameters were higher than 0.8. The completion time for evaluation with the remote slit lamp and the slit lamp were 247.3±153.5 and 123.5±53.7 seconds, respectively (P<0.001). CONCLUSIONS: Slit-lamp photo imaging is a superior method for examination of trabeculectomy eyes compared with 2D photo imaging. The remote slit-lamp system shows similar potential to the slit-lamp system for the evaluation of trabeculectomy eyes, although the evaluation time is much longer.
