BACKGROUND AND OBJECTIVE
To evaluate the effect of the degree of scleral indentation with a modified AlGaAs diode laser for transscleral retinopexy in the rabbit.
MATERIALS AND METHODS
Transscleral diode laser photocoagulation was performed on the eyes of Dutch-belted rabbits using a modified AlGaAs diode laser with a wider base and various prism protrusions.
RESULTS
The transscleral photocoagulation generally became more efficient with an increasing amount of scleral indentation. Effectiveness increased up to a prism protrusion of 1.5 mm.
CONCLUSION
This study shows that a wide-based AlGaAs diode laser with a 1.5-mm protrusion provides a more easily oriented probe for creating more efficient chorioretinal burns.
背景与目的
评估改良型砷化铝镓二极管激光进行巩膜压陷程度对兔经巩膜视网膜光凝术的影响。
材料与方法
使用具有更宽底座和不同棱镜突出度的改良型砷化铝镓二极管激光，对荷兰带兔的眼睛进行经巩膜二极管激光光凝术。
结果
随着巩膜压陷量增加，经巩膜光凝术通常变得更有效。直至棱镜突出度达到1.5毫米时，有效性增加。
结论
本研究表明，具有1.5毫米突出度的宽底座砷化铝镓二极管激光提供了一个更易于定位的探头，用于产生更有效的脉络膜视网膜烧伤。
