Abstract 
 
Abstract:
 

Thin central corneal thickness (CCT) is recognized as a risk factor for glaucoma. The aim of the study was to evaluate the role of CCT on the outcomes of selective laser trabeculoplasty (SLT). A retrospective chart review of all SLT procedures performed at the University Eye Clinic in Dallas from July 2003 – July 2004. Records of 109 patients (148 eyes) were reviewed. Fifty–six patients were excluded due to previous intraocular surgery or insufficient follow–up. The mean CCT of the remaining 81 eyes of 53 individuals was 535.6 ± 36.5 µm. The patients were divided into 3 groups: A (CCT 500 – 571 µm; 51 eyes), B (CCT > 571 µm; 15 eyes), C (CCT <500 µm; 15 eyes). The results are as follows:

 

 

T–test analysis comparing groups B and C were significant at p = 0.035. But comparisons between groups A and B or A and C were not significant. There appears to be a trend towards an inverse relationship between CCT and the amount of IOP reduction following SLT. However, this was only found to be statistically significant when comparing patients with thick CCT to thin CCT. Individuals with thin CCT may experience greater pressure reduction after SLT.
