Purpose: To evaluate images taken with OTI-OPKO Spectral domain optical coherence tomography (OCT; OTI-OPKO Health Inc, Miami, FL)/scanning laser ophthalmoscope (resolution of 5-8 mu m) and compare them with conventional StratusOCT (Carl Zeiss Meditec Inc, Dublin, CA) in eyes with epiretinal membranes (ERMs), macular edema, and vitreoretinal interface abnormalities. Methods: We evaluated 79 consecutive eyes with retinal pathologies using Spectral OCT/scanning laser ophthalmoscope and StratusOCT at the Jacobs Retina Center, University of California San Diego, CA. Pathologies included ERM, macular edema, and vitreomacular traction. Two masked reviewers graded the pathologic findings on the basis of visibility (scale 0-III). A quantitative continuous scale grading system was also used. Results: Statistical analysis showed significant differences in ERM visibility between the spectral OCT/scanning laser ophthalmoscope and StratusOCT (P < 0.0001; signed-rank test). Furthermore, posterior hyaloid visibility was significantly different (P < 0.0001) as was the macular edema grading (P < 0.0001). The Gaussian noise grading system was performed for a smaller subset of 40 eyes and it gave the same results. Spectral OCT was particularly useful in the diagnosis of subtle ERM, minimal diffuse macular edema, and morphology of macular cystic spaces, posterior vitreous detachment, and attachments of the posterior hyaloid. Conclusion: The Spectral OTI-OPKO instrument allows significantly better visualization of vitreoretinal surface diseases like ERM, posterior hyaloid, and retinal edema than StratusOCT. High-speed Spectral OCT/scanning laser ophthalmoscope allows rapid image acquisition, higher number of cuts, and better sampling yielding superior imaging of retinal pathology.
