IOP better controlled in eyes with thin corneas treated with SLT

Eyes that have a thin cornea and are primarily treated with selective laser trabeculoplasty for ocular hypertension or primary open-angle glaucoma demonstrate high IOP control, according to a study.
The retrospective review analyzed 80 eyes of 47 consecutive patients who underwent SLT as the primary treatment for either ocular hypertension or primary open-angle glaucoma.
Eyes were divided into either a thin cornea group with a central corneal thickness of less than 555 µm or a thick cornea group with a central corneal thickness of 555 µm or more. Postoperative data were reviewed at 2 weeks and at months 3, 6, 9, 12, 24 and 30.
The mean percentage of IOP reduction was significantly greater in the thin cornea group than in the thick cornea group at months 3, 6, 9, 12 and 30 (P < .05).
“The results of our study suggest that eyes with thinner corneas, which may be at higher risk for progression, may also show a better long-term response to SLT over at least 30 months,” the study authors said. “A possible explanation for this finding is the difference in the baseline IOP. Although the baseline applanation IOP was not statistically different between the two groups, the actual IOP may be higher in the thinner cornea group.”
