“…In the current study, no statistically significant difference was found between the nasal and temporal measurements of the SC area and diameter in all groups. Monsoori et al 21 also detected no significant difference in the nasal and temporal SC area and diameter in the control group or the acute angle-closure glaucoma group. Hong et al 22 reported that the temporal SC area and diameter were larger in both controls and patients with primary open-angle glaucoma, but this did not reach statistical significance.…”

Objectives: In this study, we aimed to evaluate Schlemm canal parameters using anterior segment swept-source optical coherence tomography in eyes that underwent keratoplasty and compare them with keratoconus and healthy control groups. Methods: The study included 32 patients who underwent penetrating keratoplasty or deep anterior lamellar keratoplasty once due to keratoconus and age-matched and sex-matched 20 keratoconus patients and 30 healthy controls. In all the patients, a single horizontal image centered on the central cornea was obtained from the nasal and temporal quadrants with low-intensity scanning to visualize Schlemm canal. Results: There was no statistically significant difference between the groups for age and gender (P˃0.05). In the keratoplasty group, the area and diameter of Schlemm canal were 2.266±1.141μm2 and 160.77±65.08 μm, respectively, in the nasal quadrant and 2.623±1.277 μm2 and 158.81±68.05 μm, respectively in the temporal quadrant, which were statistically significantly lower compared with other groups (P<0.001 for all). There was no significant difference between the penetrating and deep anterior lamellar keratoplasty subgroups for Schlemm canal parameters. Conclusion: This is the first study to report anterior segment optical coherence tomography after surgery shows SC parameters that are, on average, less than age-matched and keratoconus controls.
