E-mail: kothari_ar@yahoo.com BEST PAPER OF RETINA VITREOUS-II SESSION O ver the past decade, optical coherence tomography (OCT) has transformed retina practices. OCT has enabled in vivo near histological imaging of retinal conditions and led to better understanding of anatomical alterations in various retinal diseases. Presently, OCT is primarily applied to image posterior pole pathology alone. Its capabilities at imaging extra- macular lesions in vivo have not been explored hitherto. Several peripheral retinal lesions can be imaged using current OCT machines. A few modifications in the standard acquisition parameters and proper eye positioning are necessary to obtain peripheral OCT scans. This study was aimed at imaging lesions in the retinal periphery, examining their structure and the utility of this exercise. Materials and Methods Ten eyes of seven patients with lesions of the peripheral retina were subjected to OCT imaging. Satisfactory imaging was obtained in eight eyes of six patients. Imaging was done using the standard time domain OCT -Stratus 3 (Carl Zeiss, Dublin, CA) and newer spectral domain OCT- Cirrus (Carl Zeiss, Dublin, CA) instruments. One of the important prerequisites of peripheral retinal imaging with OCT is maximal pupillary dilation. The patient was seated as usual and instructed to look in the direction of the quadrant of interest. An assistant was required to retract the lids. Line scan was selected from the acquisition protocol panel. The line length was adjusted to maximal possible-10 mm. The line orientation was kept perpendicular to lesion
