Purpose:To evaluate the imaging characteristics of selected choroidal disease using the SLO OCT. Methods:A retrospective review was made of cases of choroidal disease imaged using the SLO–OCT (OCT Ophthalmoscope, University of Kent, Canterbury; UK for OTI, Toronto, Canada). Longitudinal and coronal scans were analyzed to determine if useful information could be derived from these images. Results:Between April and November 2003, eight patients with the following choroidal pathologies were seen: choroidal rupture, choroiditis, polypoidal choroidopathy, choroidal vasculopathy, choroidal granuloma. The extent of damage to the choroid and changes in the choroidal bed were evident from the scans examined. There seemed to be an improved visualization of the choroid compared to the OCT3, and this may be attributed to the manner in which images are acquired. Due to en face (transverse) scanning, the OCT image is continuous along the line of the raster, as opposed to the images generated by the OCT 3 which utilizes axial scanning. Conclusions:En face imaging results in superior resolution in both longitudinal and coronal scans, which allows excellent visualization of changes in choroidal lesions.
