Abstract. Purpose:To report findings by optical coherence tomography(OCT)of the fundus treated by Nd-YAG laser using conventional method and Pattern Scan Laser(PASCAL®). Cases and Method:This prospective study was made on 7 eyes of 5 patients with proliferative diabetic retinopathy. Fourier domain OCT was used to evaluate the fundus immediately,2 weeks and 4 weeks after photocoagulation. Results:Fundus areas treated by conventional method showed high-intensity reflex from the choroid to internal limiting membrane immediately after treatment. Areas treated by PASCAL® showed high-intensity reflex from the retinal pigment epithelium(RPE)to outer retinal layer immediately after treatment and changes limited to the RPE 4 weeks after treatment. Conclusion:Inner retinal layers showed no or minimum changes following Nd-YAG laser photocoagulation using PASCAL®. This finding seems to imply that neural retinal function is more spared from damage than by conventional method of photocoagulation.
