Dry eye disease is a significant public health problem globally. The magnitude of the dry eye disease problem in Africa is, however, unknown. This study provides important and lacking information on dry eye disease in Africa.

This study aimed to estimate the prevalence of dry eye disease in Africa.

A systematic online literature search was conducted for articles on dry eye disease in Africa. Meta-analysis was conducted to estimate the prevalence of dry eye disease in Africa and meta-regression to explore the association between dry eye and sex, age, study population, country of study, and type of study.

The overall prevalence estimate of dry eye disease in Africa was 42.0% (95% confidence interval [CI], 30.7 to 53.8%). The prevalence rates of dry eye disease in male and female individuals were 42.1% (95% CI, 28.5 to 56.3%) and 44.4% (95% CI, 30.2 to 59.0%), respectively; in South Africa, Ghana, Nigeria, and Egypt, the rates were 54.9% (95% CI, 39.0 to 70.4%), 38.3% (95% CI,17.7 to 61.4%), 41.4% (95% Ct requires immediate attention and action. More epidemiological studies in Africa are needed to fully understand this problem to inform policy decisions.

Low vision rehabilitation clinicians must sometimes evaluate stand magnifiers to determine their true optical properties. A novel method is described for measuring the image distance of stand magnifiers.

We describe a new method for determining the image distance of stand magnifiers, which has some advantages over previously described methods.

Diverging light emerging from a stand magnifier is brought to a focus on the ceiling or other flat surface using convex lenses placed on the top of the stand magnifier lens. read more Knowing the power of this convex lens and the distance from the magnifier lens to the imaging surface, one can calculate the degree to which the emerging light is diverging and, from that, the image distance. Each author evaluated three stand magnifiers using this method and compared our results with each other and with the values for image distance published by the manufacturer.

Our method produced measurements that were consistent between three clinicians, with emerging divergence values d.

Digital display use has been accepted as a contributing factor to dry eye disease. Nowadays, plenty of new models of digital displays have been developed, and the differences in their nature and the ways in which they are set and used may contribute to differences in the eye-related problems they cause.

This study aimed to analyze the differences in ocular surface, tear film, and visual fatigue parameters after reading on different digital displays, with and without initial instillation of artificial tears.

Thirty-one healthy individuals ranging in age from 20 to 26 years (mean ± standard deviation, 21.26 ± 1.73 years) were included in this prospective clinical study. Subjects’ ocular surface, tear film, and visual fatigue parameters were assessed after reading for 15 minutes on a laptop computer, tablet, e-reader, and smartphone with matching characteristics and a baseline measurement. Measurements were taken with and without the instillation of artificial tears before the reading tasks and included thvices.

Taking into account the clinical tests for dry eye diagnosis, the smartphone may be considered as the least disturbing display, producing lower dry eye signs and symptoms in comparison with other devices.

This report shares the long-term outcomes of an uncommon use of prosthetic replacement of the ocular surface ecosystem (PROSE) treatment and scleral lenses in the treatment for patients with ptosis who are not surgical candidates.

This study aimed to describe a case of pediatric traumatic lid ptosis and follow-up during an 8-year period with PROSE treatment.

A 7-year-old Honduran girl presented with a history of severe cranial, facial, and ocular trauma as a result of a motor vehicle accident. Significant ptosis with left-sided facial paralysis and irregular astigmatism significantly reduced the patient’s visual function in the left eye. She was evaluated and treated with a scleral prosthetic device in the left eye to improve vision, the ocular surface, and overall function for activities of daily living. After 8 years of PROSE treatment, acuity in the left eye remained stable at 20/25. The corneal health remained stable throughout this period, without complications of corneal neovascularization or corneal edema.

Prosthetic replacement of the ocular surface ecosystem treatment provided support of the ocular surface and mechanical left upper eyelid lift in a traumatic eyelid ptosis, ultimately providing improved visual function during an extensive 8-year period in a pediatric patient. Further studies are needed to evaluate the applicability of this approach in broader ptosis cases.

A symptom cluster is a group of 2 or more symptoms that occur together and are related to each other. Although family caregivers of individuals with cancer experience multiple concurrent symptoms, the majority of symptom research has focused on assessing and managing individual, isolated symptoms.

The study purpose was to investigate symptom clusters in cancer caregivers and to explore factors that influence symptom clusters.

Cluster analysis was performed using cross-sectional survey data from 129 family caregivers of individuals receiving cancer treatment at the National Institutes of Health Clinical Center. PROMIS (Patient-Reported Outcomes Measurement Information System) measures of 5 common symptoms in caregivers (fatigue, sleep disturbance, depression, anxiety, impaired cognition) were used to identify symptom clusters.

Two symptom cluster groups were identified low symptom burden (n = 106, 82.2%) and high symptom burden (n = 23, 17.8%). Individuals who reported higher levels of caregiving burden (impact on health subscale) (β = 1.
