    1. Morphologic Features of Crystalline Lens in Patients with Primary Angle Closure Disease Observed by CASIA 2 Optical Coherence Tomography

      Morphologic Features of Crystalline Lens in Patients with Primary Angle Closure Disease Observed by CASIA 2 Optical Coherence Tomography

      Purpose : To investigate the morphologic features of crystalline lens in primary angle closure disease (PACD) by the swept-source anterior segment optical coherence tomography. Methods : This cross-sectional observational study included 125 consecutive eyes from 125 patients who underwent anterior segment optical coherence tomography (CASIA 2, Tomey, Nagoya, Japan) examination, including 38 eyes of normal controls, 57 eyes of PAC suspects (PACS), and 30 eyes with PAC or PAC glaucoma (PACG). Crystalline lens parameters were compared among the three groups. Spearman correlation analysis and multiple linear regression models were performed to evaluate the relationships between the lens parameters and related factors. Results ...

    2. Clinical features of microvasculature in subzones of parapapillary atrophy in myopic eyes: an OCT-angiography study

      Clinical features of microvasculature in subzones of parapapillary atrophy in myopic eyes: an OCT-angiography study

      Purpose To investigate the microvasculature in subzones of parapapillary atrophy (PPA) and their associated factors in healthy myopic eyes using optical coherence tomography (OCT) angiography. Methods The cross-sectional study included 55 healthy myopic eyes with PPA. The superficial radial peripapillary capillary (RPC) and choroidal microvascular densities were delineated and measured in alpha, beta, and gamma zone PPA using OCT angiography, respectively. The structural parameters including the width and area in each subzone and corresponding retinal nerve fiber layer thickness were further measured. Statistical analysis was performed to explore the relationship between the vascular and structural parameters. Results The mean age ...
