AI Article Synopsis
- The study assessed astaxanthin's antioxidative effects by measuring superoxide scavenging activity and levels of hydrogen peroxide in human aqueous humor of 35 cataract surgery patients.
- After two weeks of astaxanthin supplementation (6 mg/day), results showed a significant increase in superoxide scavenging activity and a decrease in total hydroperoxide levels.
- There was a negative correlation between superoxide scavenging activity and total hydroperoxide levels, suggesting astaxanthin may help in managing oxidative stress-related diseases.
Article Abstract
We evaluated the antioxidative effects of astaxanthin through the changes in superoxide scavenging activity, levels of hydrogen peroxide and total hydroperoxides in human aqueous humor. The study subjects were 35 patients who underwent bilateral cataract surgery on one side before and the other side after intake of astaxanthin (6 mg/day for 2 weeks). Their aqueous humor was taken during the surgery and subjected to measurements of the three parameters. After astaxanthin intake, the superoxide scavenging activity was significantly (p<0.05) elevated, while the level of total hydroperoxides was significantly (p<0.05) lowered. There was a significant negative correlation between the superoxide scavenging activity and the level of total hydroperoxides (r = -0.485, p<0.01), but no correlations between the hydrogen peroxide level and the other two parameters. Astaxanthin intake clearly enhanced the superoxide scavenging activity and suppressed the total hydroperoxides production in human aqueous humor, indicating the possibility that astaxanthin has suppressive effects on various oxidative stress-related diseases.

Feline coronavirus (FCoV) is a virus endemic in cat populations. Specific genomic mutations give it a strong tropism for macrophages, allowing systemic infection and the development of a disease known as feline infectious peritonitis. This disease takes various clinical presentations, and can manifest as uveitis.

Purpose: This study evaluates the discrepancies between ACV measurements obtained from the Heidelberg Anterion and Zeiss IOLMaster 700 and investigates the significance of ACV and other ocular biometry parameters.
Patients And Methods: To investigate intraocular fluid circulation, a robust formula was developed for ACV measurement using the Zeiss IOLMaster 700. A pilot study was conducted to validate this formula, which relied on WTW, CCT, and ACD.

Purpose: To evaluate the advantages and clinical utility of metagenomic sequencing (MGS) in diagnosing infectious uveitis pathogens.
Methods: A retrospective study was conducted on 20 infectious uveitis patients (20 eyes) who received treatments at the Affiliated Eye Hospital of Shandong University of Traditional Chinese Medicine from May 2020 to February 2021. Anterior aqueous humor of the patients was collected and analyzed using MGS.

This study aimed to evaluate the changes in cytokine levels in the aqueous humor and factors of treatment resistance following intravitreal faricimab injection in treatment-naïve patients with neovascular age-related macular degeneration. A total of 32 eyes were analyzed before and after a single faricimab injection. Although the best-corrected visual acuity (BCVA) showed no significant improvement, the mean central retinal thickness decreased significantly by 73.
