在激光小梁成形术（LTP）或激光虹膜切开术之前和之后一年，通过角膜内皮显微镜进行角膜内皮的形态计量学研究。在小梁成形术后6个月和虹膜切开术后3个月，内皮细胞大小显著增加。激光虹膜切开术后细胞大小的增加幅度与输送到眼睛的激光能量的量显著相关。然而，在LTP后，在目前治疗的病例中，施加的能量保持相当恒定，未证明这种相关性。细胞大小的增加与临床因素无关，包括激光治疗前后的IOP、年龄和是否存在内皮烧伤。使用降低能量的治疗方案适用于最大限度地减少LTP或激光虹膜切开术诱导的内皮损伤。
The morphometric study of the corneal endothelium was carried out by means of specular microscopy prior to and for one year following laser trabeculoplasty (LTP) or laser iridotomy. A significant increase in the endothelial cell size was demonstrated in 6 months after trabeculoplasty and in 3 months following iridotomy. The magnitude of increase in cell size following laser iridotomy was significantly correlated with the amount of laser energy delivered to the eye. However, such correlation was not demonstrated following LTP where the applied energy was kept fairly constant among the present treated cases. The increase in cell size failed to correlate with clinical factors including IOP before and after laser therapy, age and the presence or absence of endothelial burn. The treatment protocols using reduced energy are indicated to minimize endothelial damage induced by LTP or laser iridotomy.
