Pan retinal photocoagulation for proliferative diabetic retinopathy. These 600 micron burns were obtained by using a 3x3 array.

Laser photocoagulation demarcation surrounding posterior retinal tear adjacent to retinal venule with sub-clinical retinal detachment in a patient with preceeding blunt trauma. These 400 micron burns were obtained using a combination of modified grid and 3x3 pattern arrays.

Complete Pan retinal photocoagulation for proliferative diabetic retinopathy. These burns were obtained using a variety of square array patterns with a pulse duration set at 20ms.

Pan retinal photocoagulation for proliferative diabetic retinopathy. The burns on the left side of the fundus photograph were the result of conventional, single spot photocoagulation. The arrayed burns were obtained with the Pascal Method of Photocoagulation.

Macular Grid for clinically significant diabetic macular edema. The extrafoveal burns on the superonasal hemisphere of the fundus image were the result of conventional single spot treatment. The burns on the lower, inferotemporal extrafoveal region were obtained by means of the Pascal Method of Photocoagulation.
