A third group included healthy subjects.Result: 98 subjects were selected. Patients with POAG or OHT using PG eyedrops showed a significant iris thickness reduction at DMR compared to healthy subjects and to patients using hypotensive eyedrops not containing PG. Significantly higher SMR thickness values were found in PG group compared to both control groups. DMR/SMR ratio significantly reduced in PG group.

However, direct comparisons of switching from tafluprost to TTFC are limited.Objective: To investigate the efficacy and safety of switching from tafluprost to TTFC in patients with Primary Open-Angle Glaucoma (POAG).Methods: Thirty-four eyes (34 patients) with POAG that did not achieve adequate IOP reduction on tafluprost were switched to TTFC with no washout period. IOP, systolic/diastolic blood pressure and pulse rate were measured 1 and 3 months later and compared with baseline values. All participants were asked about specific adverse reactions after 1 and 3 months of treatment. Patients also completed a questionnaire about preference and adherence after 1 month of treatment.Results: Mean IOP after 1 and 3 months was significantly lower than at baseline (14.2 ± 2.1 mmHg and 14.1 ± 2.3 mmHg, respectively, vs 16.0 ± 2.0 mmHg, P < 0.0001). Systolic/diastolic blood pressure and pulse rate were not significantly different from baseline after 1 and 3 months. The questionnaire indicated that the frequency of missing a dose was not different before (27.3%) or after (18.2%) switching to TTFC (P = 0.2371). There were five reports of adverse reactions (14.7%), including a corneal epithelium disorder, ocular irritation, skin irritation at the wrist, and chest pain.

NCT and DCT measurements were obtained within thirty minutes. The right eye IOP measurements were compared with paired t-test, and Bland- Altman plot analysis. The left eye IOP measurements were subsequently analyzed for confirmation of results.Results: There were 106 subjects with complete right eye data, and 104 subjects with complete left eye data. The average age was 72 years, and 70% were female. The NCT IOP was on average 3.9 mm Hg lower in the right eye, and 3.5 mm Hg lower in the left eye compared with DCT.

CCT was measured by the same examiner using the Cirrus 5000 HD-OCT and Pentacam HR. The results of CCT obtained by each method were averaged and compared using t-test analysis. The agreement between the measurement methods was evaluated. Coefficient of Repeatability (CoR) and Intra-Class Correlation Coefficient (ICC) were computed.Results: The mean measurements taken with the Cirrus OCT anterior chamber lens (CCTAC), HD cornea lens (CCTHDC) and pachymetry scans (CCTPach) were 545.35 ± 31.02, 537.87 ± 26.82, and 532.04 ± 29.82 µm, respectively. The mean CCT obtained with the Pentacam (CCTPent) was 545.51 ± 30.71 µm. CCTPent were significantly higher than CCTHDC and CCTPach (p< 0.0001). In contrast, the CCTPent and CCTAC were similar (p=0.87). CCT, as evaluated by the two different instruments, showed excellent correlation (r > 0.98, p< 0.0001) with an ICC > 0.99 (95% CI, 0.97 - 0.99). CoR was the highest for CCTPach (3.7 ± 1.4, 95% CI (3.0- 4.6)).Conclusion: CCT measurements from the Cirrus OCT using the new anterior segment lens attachments and the Pentacam HR are highly correlated.

As refractive errors are a major contributor of mild to moderate vision impairment, assessment of their relative proportion would be helpful in the strategic planning of health programs.Purpose: To determine the pattern of the relative proportion of types of refractive errors among the adult candidates seeking laser assisted refractive correction in a private clinic setting in Saudi Arabia.Methods: The clinical charts of 687 patients (1374 eyes) with mean age 27.6 ± 7.5 years who desired laser vision correction and underwent a pre-LASIK work-up were reviewed retrospectively. Refractive errors were classified as myopia, hyperopia and astigmatism.
