Thinner Central Corneal Thickness is Associated with a Decreased Parapapillary Vessel Density in Normal Tension Glaucoma.

This retrospective cross-sectional study, which enrolled 124 normal tension glaucoma (NTG) eyes and 68 healthy eyes as the control, determined the association between central corneal thickness (CCT) and ocular parameters in NTG. CCT was measured using the Pentacam® system, optical coherence tomography angiography (OCT-A) was adopted to measure the peripapillary and macular area VDs, and spatial data were based on the Garway-Heath map as illustrated in OCT-A. Univariate and multivariate linear regressions were used to statistically analyze for associations between CCT and other factors.

Optic disc hemorrhage in nonglaucomatous eyes: A cross-sectional study with average 8-year follow-up.

Purpose: To characterize changes in the retinal nerve fiber layer (RNFL) and peripapillary vessel density (VD) at the site of disc hemorrhage (DH) in nonglaucomatous eyes.

Materials And Methods: This retrospective cross-sectional study included nonglaucomatous eyes diagnosed with unilateral DH. The change of DH was recorded using disc photography.

Epidemiology and the Estimated Burden of Microbial Keratitis on the Health Care System in Taiwan: A 14-Year Population-Based Study.

Purpose: To investigate the epidemiologic characteristics of microbial keratitis and its overall burden on the health care system in Taiwan.

Design: Retrospective, population-based study.

Methods: We conducted a study using claims data in the Taiwan National Health Insurance Research Database in 2000-2013, employing diagnoses, drugs, and procedure codes to define diseases and procedures.

Baseline clinical features predict visual outcome in young patients with central retinal vein occlusion.

Purpose: To evaluate prognostic factors in young patients with central retinal vein occlusion (CRVO).

Methods: Retrospective case series. CRVO patients aged ≤ 50 and follow-up ≥ 6 months were enrolled.

Normal tension glaucoma in obstructive sleep apnea syndrome: A structural and functional study.

This study characterized and evaluated normal tension glaucoma (NTG) in obstructive sleep apnea syndrome (OSAS).In this retrospective, cross-sectional study, all participants were examined with polysomnography (PSG). Functional parameters of standard automated perimetry (SAP) were recorded.
