Purpose: To evaluate the impact of lens opacity on the reliability of optical coherence tomography angiography metrics and to find a vessel caliber threshold that is reproducible in cataract patients.
Methods: A prospective cohort study of 31 patients, examining one eye per patient, by applying 3 × 3 mm macular optical coherence tomography angiography before (18.94 ± 12.
Background: We compared with and without enhanced depth imaging mode (EDI) in semi-automated quantification of retinal and choroidal biomarkers in optical coherence tomography (OCT) in patients with diabetic retinopathy (DR) or retinal vein occlusion (RVO) complicated by macular edema. We chose to study three OCT biomarkers: the numbers of hyperreflective foci (HF), the ellipsoid zone reflectivity ratio (EZR) and the choroidal vascularity index (CVI), all known to be correlated with visual acuity changes or treatment outcomes.
Methods: In a single examination, one eye of each patient ( = 60; diabetic retinopathy: = 27, retinal vein occlusion: = 33) underwent macular 870 nm spectral domain-OCT (SD-OCT) B-scans without and with EDI mode.
Purpose: Ellipsoid zone (EZ) integrity is identified as a potential biomarker for therapy surveillance and outcome prediction of visual acuity (VA). However, only a few studies report long-term results of over 1 year of clinical and anatomical changes in patients with diabetic macular edema (DME). This study is aimed at describing the long-term VA and anatomical outcomes in spectral domain optical coherence tomography (OCT) (relative ellipsoid zone reflectivity ratio, central macular thickness, and volume) in patients with DME treated with antivascular endothelial growth factor (anti-VEGF) therapy.

Article Synopsis
- A study analyzed erythropoietin levels in the tear film and blood plasma of 63 individuals, including 30 with normal vision (emmetropia) and 33 with myopia.
- Among the myopic participants, 17 were soft contact lens users, but there were no significant differences in erythropoietin levels between the groups.
- The findings confirmed a normal physiological level of erythropoietin in the tears of myopic volunteers who wear soft contact lenses.
Erythropoietin level was evaluated in blood plasma and tear fluid of humans with normal functions of eye and normal blood characteristics. We examined 21 patients. Principle ability of erythropoietin level detection in patient's tear fluid ascertained.
