Effect of Central Corneal Thickness on the Long-Term Outcome of Selective Laser Trabeculoplasty as Primary Treatment for Ocular Hypertension and Primary Open-Angle Glaucoma

Abstract

In patients with POAG and OHT, percentage of IOP reduction after SLT was significantly greater in eyes with thinner corneas (CCT < 555 μm). These findings indicate that patients treated with SLT as primary therapy who had thinner corneas demonstrated better IOP control for at least 30 months after SLT.

Preoperative intraocular pressure as a predictor of selective laser trabeculoplasty efficacy

“…Shazly et al. () showed that patients with HPG and ocular hypertension and a CCT of <555 μ m had a better pressure‐lowering response to SLT than those with a CCT of more than 555 μ m. The explanation for these findings might be that IOP is actually higher in eyes with thinner corneas. The mean baseline IOP for thin corneas in that study was 24 (SD 3.6) mmHg and 23.6 (SD 2.8) mmHg for thick corneas.…”

The thick and thin of the central corneal thickness in glaucoma

“…Treatment of OHTN and POAG with selective laser trabeculoplasty (SLT) showed a significantly greater reduction in eyes with thin CCT (<555 µm) over a 30-month period [111].…”

Anterior Segment Optic Coherence Tomography Changes Before and After Phacoemulsification in Primary Open Angle Glaucoma

“…It is independent of age and ocular biometric values. Anterior chamber dynamics during surgery may lead to a greater postoperative CCT due to tissue damage and endothelial cell damage (22,23). Different techniques, such as optical slit scanning pachymetry, partial coherence interferometry, OCT, confocal biomicroscopy, specular microscope, and the Pentacam Scheimpflug-imaging system (OCULUS Optikgeräte GmbH, Wetzler.…”
