Full-thickness scleral diathermy using a standard electrode causes significant scleral damage and necrosis. Use of a modified (Jabbour's) diathermy electrode appears to cause minimal scleral damage. We evaluated the scleral changes following transscleral diathermy application using standard and modified diathermy electrodes to the peripheral retina and ciliary body. Twelve Dutch belted pigment rabbits were used in our experiment. Three eyes each were subjected to transscleral diathermy using standard and modified electrodes to produce chorioretinal scars and cyclodestruction. Eyes were examined with the slit lamp and indirect ophthalmoscope at weekly intervals for 4 weeks. Light and transmission electron microscopy was performed 1 hour after diathermy application in 4 animals and in the remaining 8 animals at 4 weeks. Chorioretinal scarring and ciliary body atrophy were successfully induced with both types of electrodes. However, scleral damage was less severe in eyes treated with the modified electrode as compared with the standard electrode.
使用标准电极进行全层巩膜透热疗法会导致明显的巩膜损伤和坏死。使用改良型（贾布尔氏）透热电极似乎造成的巩膜损伤最小。我们评估了使用标准和改良透热电极对周边视网膜和睫状体进行经巩膜透热疗法后巩膜的变化。我们的实验使用了12只荷兰带兔。分别用标准电极和改良电极对三只眼睛进行经巩膜透热疗法，以产生脉络膜视网膜瘢痕和睫状体破坏。每周用裂隙灯和间接检眼镜检查眼睛，持续4周。4只动物在透热疗法应用后1小时进行光镜和透射电子显微镜检查，其余8只动物在4周时进行检查。两种电极均成功诱导了脉络膜视网膜瘢痕形成和睫状体萎缩。然而，与标准电极相比，用改良电极治疗的眼睛巩膜损伤较轻。
