ObjectiveTo compare the diagnostic values of the Schirmer’s and tearfilm breakup time (TBUT) tests and the Ocular Surface Disease Index (OSDI) in dry-eye syndrome.Subjects and methodsThirty-five employees of Ümraniye Training and Research Hospital who used computers in their daily work participated in this prospective study. All participants completed the OSDI. Following routine ophthalmologic examination, the TBUT and Schirmer’s test were undertaken and outcomes were compared.ResultsThe mean age was 29.09 ± 6.73 (range 20–46) years. Mean OSDI questionnaire, TBUT, and Schirmer’s test scores were detected as 37.12 ± 19.05 (range 4–75), 11.37 ± 3.69 seconds (range 4–18 seconds), and 25.80 ± 8.43 mm (range 6–35 mm), respectively. There was a significant inverse correlation between the OSDI and TBUT scores (r = −0.385, P = 0.022). No significant correlation existed between the OSDI and Schirmer’s test scores.ConclusionDry eye is a common problem among computer users. The OSDI questionnaire, used together with the TBUT, is easily performed and may be of benefit in supporting the diagnosis of dry-eye syndrome.

Highly myopic subjects tend to have thinner RNFL and GCC thicknesses than subjects with low and moderate myopia.

The results of this study revealed that accelerated corneal collagen cross-linking stabilized the progression of keratoconus without a significant endothelial cell density loss during the 12 months of follow-up.

Both Brinz/Tim and Dorz/Tim showed similar significant and clinically relevant IOP-lowering efficacy, whereas Brinz/Tim provided superior outcomes in terms of ocular comfort.

Purpose:The objective of this study is to evaluate the diagnostic ability of retinal nerve fiber layer (RNFL), macular, optic nerve head (ONH) parameters in healthy subjects, ocular hypertension (OHT), preperimetric glaucoma (PPG), and early glaucoma (EG) patients, to reveal factors affecting the diagnostic ability of spectral domain-optical coherence tomography (SD-OCT) parameters and risk factors for glaucoma.Methods:Three hundred and twenty-six eyes (89 healthy, 77 OHT, 94 PPG, and 66 EG eyes) were analyzed. RNFL, macular, and ONH parameters were measured with SD-OCT. The area under the receiver operating characteristic curve (AUC) and sensitivity at 95% specificity was calculated. Logistic regression analysis was used to determine the glaucoma risk factors. Receiver operating characteristic regression analysis was used to evaluate the influence of covariates on the diagnostic ability of parameters.Results:In PPG patients, parameters that had the largest AUC value were average RNFL thickness (0.83) and rim volume (0.83). In EG patients, parameter that had the largest AUC value was average RNFL thickness (0.98). The logistic regression analysis showed average RNFL thickness was a risk factor for both PPG and EG. Diagnostic ability of average RNFL and average ganglion cell complex thickness increased as disease severity increased. Signal strength index did not affect diagnostic abilities. Diagnostic ability of average RNFL and rim area increased as disc area increased.Conclusion:When evaluating patients with glaucoma, patients at risk for glaucoma, and healthy controls RNFL parameters deserve more attention in clinical practice. Further studies are needed to fully understand the influence of covariates on the diagnostic ability of OCT parameters.
