Analysis of Indicators for Assessing the Risk of Progression from PACS to APAC and the Degree of Intraocular Pressure Elevation in APAC Using AS-OCT.

Objective: The aim of this study is to quantify anterior chamber parameters to provide potential risk indicators for evaluating the progression of primary angle-closure suspect (PACS) eyes to acute primary angle closure (APAC) and the degree of intraocular pressure elevation in patients with APAC utilizing anterior segment optical coherence tomography (AS-OCT).

Methods: Tomey CASIA2 AS-OCT was used to quantitatively measure various anterior chamber parameters, including anterior chamber depth (ACD), anterior chamber volume (ACV), lens thickness (LT), lens vault (LV), iris-trabecular contact index (ITC), iris thickness (IT), iris volume (IV), iris curvature (IC), iris area (IA), and iris thickness (IT), in APAC eyes (30 eyes) and contralateral PACS eyes (30 eyes) of 30 patients. The differences in these parameters between the two groups and their relationship with intraocular pressure were analyzed.

Association of daily selenium intake and glaucoma: A cross-sectional study.

The association between dietary selenium intake and glaucoma remains unclear. Using data from the 2005 to 2008 National Health and Nutrition Examination Survey (NHANES), this study aimed to investigate the relationship between glaucoma and dietary selenium intake. The study included subjects aged 40 years or older who participated in the NHANES dietary intake interview and vision health questionnaire.
