However, because of different reasons, single session is less frequently practiced. We describe the results of a single session of pattern scan laser versus multiple sessions of conventional laser in cases of proliferative diabetic retinopathy. Methods: A prospective study was performed on 50 patients (100 eyes), in whom proliferative diabetic retinopathy was diagnosed recently. Two eyes of an individual patient were randomly assigned, one for a single session of panretinal photocoagulation using pattern scan laser and the other for multiple sessions of conventional laser. Results: Our study confirms that single session is effective and even better than conventional laser in relation to the effect of treatment. Conclusion: Complications and the associated pain are less; thus, the patient's acceptance of PASCAL was high, and a single session was well tolerated with topical anesthesia alone.
