Purpose: We developed a new imaging device that combines simultaneously OCT and SLO images in a single instrument. We investigated the efficacy of our 3-dimensional (3-D) OCT/SLO system for patients with idiopathic macular hole. Methods: Thirty eyes (28 patients) with idiopathic macular hole (5 eyes with stage a, 8 eyes with stage 2, 9 eyes with stage 3, and 8 eyes with stage 4) were included. Unlike a conventional SLO, the combined device can operate in a so-called "transversal," or "C-scan," and yields OCT images originating at the same axes and plane as the retina. The C-scan OCT images are thin cross sections of retinal and subretinal structures at a chosen depth. The system also scans laterally along a line to the retina to produce cross-sectional longitudinal OCT images as the Humphrey's system. Results: This new device precisely demonstrated the structures of the retinal layers and the pathologies in the retina, especially in patients with fluid cuff around the macular hole. Vitreo-retinal relationship, particularly vitreous traction was clearly observed in 3-D fashion. In some cases, clear separation between the outer layers of rod and cone layer and retinal pigment epithelium layer was detected. Conclusions: This new technology for the first time enabled us to observe vitreoretinal structures in 3-D fashion in patients with idiopathic macular hole.
