. The purpose of this study was to evaluate the ocular disorders in HIV positive patients attending the Cape Coast Teaching Hospital, Ghana. . A cross-sectional study using systematic random sampling was conducted on 295 HIV positive patients. Data collection consisted of semistructured questionnaires, laboratory investigation, medical profile, and ophthalmic examination. Statistical association tests including , independent -test, and ANOVA were done. A value ≤ 0.05 was considered statistically significant. . Of the 295 participants, 205 (69.5%) were on antiretroviral therapy while 90 (30.3%) were not on therapy. Majority of the participants (162, 54.9%) were in clinical stage two, followed by stages three (68, 23.1%), one (62, 21%), and four (3, 1%), respectively. The overall prevalence of ocular disorders was 5.8%. The most common HIV related ocular disorder was HIV retinal microvasculopathy (58.8%), followed by herpes zoster ophthalmicus and retinochoroiditis, both representing 11.8% of ocular disorders seen. Cytomegalovirus retinitis, Bell's palsy, and optic neuritis were the least common (5.9%). CMV retinitis recorded the highest viral load of 1,474,676 copies/mL and mean CD4 count of 136 cells/mm. The mean CD4 count for participants with HIV related ocular disorders was significantly lower compared to participants without disorders ( = 2.5, = 0.012). Participants with ocular disorders also recorded significantly higher mean viral loads than those who did not have ocular disorders ( = 2.8, = 0.006). . Lower CD4 counts and high viral load copies were associated with the manifestation of HIV related ocular disorders.

Vision loss affects more than 7 million Americans and impacts quality of life, independence, social functioning, and overall health. Common and dangerous conditions causing sudden vision loss include acute angle-closure glaucoma, retinal detachment, retinal artery occlusion, giant cell arteritis, and optic neuritis. Acute angle-closure glaucoma features ocular pain, headache, and nausea; treatment includes pilocarpine eye drops, oral or intravenous acetazolamide, and intravenous mannitol.

Purpose: To evaluate levels of 3 tear-soluble neuropeptides in dry eye patients and to identify the correlations with clinical signs and symptoms.
Methods: A total of 16 dry eye patients and 12 healthy volunteers were enrolled. Dry eye disease (DED) diagnosis was based on the 2017 Report of the Tear Film & Ocular Surface Society International Dry Eye Workshop (TFOS DEWS II).

Objective: To evaluate the effects of Moisture Chamber Goggles combined with Fluorometholone eye drops on visual function and oxidative stress in patients with dry eye disease.
Methods: A retrospective analysis was conducted on 80 patients with dry eye disease treated at Ninghai First Hospital from January 2021 to May 2023. Patients were divided into a combination group (n=40, receiving Fluorometholone eye drops and Moisture Chamber Goggles) and a monotherapy group (n=40, receiving Fluorometholone eye drops alone) based on treatment regimens.

Introduction: We explored associations between measurements of the ocular choroid microvasculature and Alzheimer's disease (AD) risk.
Methods: We measured the choroidal vasculature appearing in optical coherence tomography (OCT) scans of 69 healthy, mid-life individuals in the PREVENT Dementia cohort. The cohort was prospectively split into low-, medium-, and high-risk groups based on the presence of known risk factors (apolipoprotein E [] ε4 genotype and family history of dementia [FH]).

Cataract is the leading ocular disease of blindness and visual impairment globally. Deep neural networks (DNNs) have achieved promising cataracts recognition performance based on anterior segment optical coherence tomography (AS-OCT) images; however, they have poor explanations, limiting their clinical applications. In contrast, visual features extracted from original AS-OCT images and their transform forms (e.
