Abstract
Aim To ascertain the prevalence and pattern of eye problems in Madang Province, Papua New Guinea. Materials and methods A six-month retrospective study was performed at Madang Provincial Hospital Eye Clinic. Convenience sampling was used in this study and all patient records from January to June 2020 were included. Data was extracted using Microsoft Excel and the data included gender, age, occupation, district where the patient lived, presenting visual acuity, and diagnosis. It was then analyzed using International Business Machines Corporation's Statistical Package for the Social Sciences version 26. A p-value of ≤0.05 was considered statistically significant. Results A total of 1,715 patients received services at the eye clinic between January and June 2020, and 1,664 were included in this study. The mean age of the patients was 39.3 ± 20.3 years. There were slightly more males (50.4%) than females. The overall leading ocular morbidities were corneal ulcers and keratitis (20.7%), refractive errors (17.4%), and cataracts (16.8%). More than half of the patients (56.2%) were either visually impaired or blind. Nearly half of the patients (41.8%) traveled long distances to seek services at the eye clinic. There was a significant association between demographic characteristics, diagnosis, and level of visual impairment. Conclusion There is a high prevalence of potential causes of visual impairment and blindness in Madang Province and these conditions affect all age groups and genders. It is essential to increase accessibility to eye care services in the country.

Transl Vis Sci Technol 2023; 12:20. [PMID: 37975843 PMCID: PMC10668610 DOI: 10.1167/tvst.12.11.20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2023] [Accepted: 10/17/2023] [Indexed: 11/19/2023] Open
Abstract
Purpose There is a significant amount of literature focusing on racial inequities in utilization rates and intraoperative complications of cataract surgery. Unfortunately, little is known about racial disparities regarding the timeline of cataract surgery and intraocular lens (IOL) selection. This study investigated whether black patients have a different preoperative and postoperative cataract surgery timeline and IOL selection than white patients. Methods A total of 10,235 patients (83.47% white) were retrospectively identified from a tertiary academic center who underwent cataract surgery between 2015 and 2022. Each patient's best corrected visual acuity (BCVA), slit lamp findings, and surgical timeline were recorded. IOL selection was categorized as standard or premium. Results Black patients had significantly worse mean ± SD preoperative logMAR BCVA than white patients (0.47 ± 0.55 vs. 0.58 ± 0.70, respectively; P = 0.0117) and were significantly less likely to receive surgery within 120 days of referral (RR, 0.71 [95% confidence interval {CI}, 0.64-0.79]; P < 0.0001). White patients were 25%, 24%, and 29% less likely to follow-up than black patients at postoperative day 1, day 7, and day 30, respectively (P < 0.0001). White patients were 6.09 (95% CI, 3.49, 10.63) times more likely to receive a premium IOL compared to black patients (P < 0.0001). Conclusions Black patients experienced more delays with receiving cataract surgery but are more adherent with postoperative follow-up. Black patients were far less likely to receive a premium IOL than white patients. Translational Relevance Increased awareness of racial inequities in cataract surgery may improve the delivery of eye care to minority groups.

[PMID: 37260421 DOI: 10.1080/02713683.2023.2221415] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Revised: 05/04/2023] [Accepted: 05/31/2023] [Indexed: 06/02/2023]
Abstract
PURPOSE There has been increased interest in phytochemical antioxidants to prevent protein damage and aggregate formation in cataract treatment. In this study, the protective effect of different doses of Rb1 (GRb1), one of the ginsenosides of Panax Ginseng, in the experimental cataract model formed in chick embryos was investigated. METHODS Five different experimental groups were formed with 100 SPF fertilized eggs: Control (0.9% NaCl to physiological saline), hydrocortisone hemisuccinate sodium (HC), low dose (HC + L-GRb1 (1 mg/kg)), medium dose (HC+). M-GRb1 (2.5 mg/kg)), and high dose (HC + H-GRb1 (5 mg/kg)). All solutions were given to air sack at 15 days of incubation. On the 17th day, the bulbous oculi of the chick embryos were dissected. Cataract formations of the lenses, glutathione (GSH), malondialdehyde (MDA), total antioxidant (TAS), total oxidant (TOS) levels, Caspase-3 H-score, and TUNEL index were determined. In addition, crystalline alpha A (CRYAA) gene expression was evaluated. RESULTS Cataracts were observed in the control, HC, HC + L-GRb1, HC + M-GRb1, and HC + H-GRb1 groups with a frequency of 0%, 100%, 75%, 56.25%, and 100%, respectively. There were statistically significant differences between the control and HC groups in terms of TAS, TOS, MDA, GSH, Caspase-3 H-score, and TUNEL index (p < .05). When the therapeutic effect of the GRb1 groups was evaluated, the HC group showed significant differences with the HC + L-GRb1 and HC + M-GRb1 groups in almost all parameters (p < .05), while there was no statistical difference with the HC + H-GRb1 group (p > .05). In addition, gene expression levels differed between the groups, although not statistically significant (p > .05). CONCLUSION 1 mg/kg and 2.5 mg/kg GRb1 applications show therapeutic properties on the HC-induced cataract model. This effect is more pronounced at 2.5 mg/kg.

Antioxidants (Basel) 2022; 11:antiox11071285. [PMID: 35883773 PMCID: PMC9311900 DOI: 10.3390/antiox11071285] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Revised: 06/23/2022] [Accepted: 06/24/2022] [Indexed: 01/07/2023] Open
Abstract
A cataract is a condition that causes 17 million people to experience blindness and is the most significant cause of vision loss, around 47.9%. The formation of cataracts is linked to both the production of reactive oxygen species (ROS) and the reduction of endogenous antioxidants. ROS are highly reactive molecules produced by oxygen. Examples of ROS include peroxides, super-oxides, and hydroxyl radicals. ROS are produced in cellular responses to xenobiotics and bacterial invasion and during mitochondrial oxidative metabolism. Excessive ROS can trigger oxidative stress that initiates the progression of eye lens opacities. ROS and other free radicals are highly reactive molecules because their outer orbitals have one or more unpaired electrons and can be neutralized by electron-donating compounds, such as antioxidants. Examples of natural antioxidant compounds are vitamin C, vitamin E, and beta-carotene. Numerous studies have demonstrated that plants contain numerous antioxidant compounds that can be used as cataract preventatives or inhibitors. Natural antioxidant extracts for cataract therapy may be investigated further in light of these findings, which show that consuming a sufficient amount of antioxidant-rich plants is an excellent approach to cataract prevention. Several other natural compounds also prevent cataracts by inhibiting aldose reductase and preventing apoptosis of the eye lens.

Abstract
Objective In this study, we aimed to determine the prevalence of visually significant
cataract and associated factors among older people attending community
ophthalmic services in the central Gondar Zone, Northwest Ethiopia. Methods We conducted a community outreach-based cross-sectional study among adults
aged ≥40 years in the central Gondar Zone from 30 May to 15 June 2021. We
used systematic random sampling to select study participants.
Interviewer-administered questionnaires and ocular examinations were
performed and the data recorded. We applied binary logistic regression to
identify factors associated with visually significant cataract. Results A total of 821 participants were included, with median age 57 years. The
prevalence of visually significant cataract was 29.1% (95% CI: 26.1–32.0).
Age ≥80 years (adjusted odds ratio [AOR] = 16.9; 95% CI: 7.5–38.4), rural
residence (AOR = 1.7; 95% CI: 1.02–2.7), unmarried status (AOR = 1.9; 95%
CI: 1.2–3.2), illiteracy (AOR = 2.9; 95% CI: 1.4–6.1), unemployed status
(AOR = 1.7; 95% CI: 1.1–2.7), and sunlight exposure ≥5 hours per day
(AOR = 1.6; 95% CI: 1.04–2.4) were significantly associated with visually
significant cataract. Conclusion In this study, visually significant cataract was found to be high, which
requires immediate public health intervention.
