PURPOSE: To assess the optimum probe design and treatment parameters for transscleral diode laser retinopexy. METHODS: Transscleral diode photocoagulation was performed on the eyes of Dutch-belted @entity95 using three different transscleral probes: a straight, 400-microns diameter probe; a prism-tipped 400-microns diameter probe; and a prism-tipped 900-microns diameter probe. RESULTS: Transscleral diode photocoagulation with all three probe types was an effective method of ablating the retina and creating @entity6519 . Both the burn diameter and the mean radiant output energy requirement increased as the burn duration and probe aperture diameter was increased. @entity937 were encountered in 12% of the burns created with the straight probe. The use of the prism-tipped probes significantly reduced the incidence of retinal holes to < 4% (P < 0.005). Histopathologically, all burns were grade III in intensity with severe @entity130 . In many of the burns, there was histopathologic evidence of @entity389 . The frequency of these inner scleral changes was reduced with a long burn duration (5 seconds). CONCLUSION: This study confirms that diode transscleral photocoagulation is a feasible method of thermal retinopexy. The use of the prism-tipped probes and long duration burns resulted in the fewest adverse reactions.
