Myopia prevalence in Finland doubled from 1930s to 1950s birth cohorts and is linked to educational attainment

Acta Ophthalmologica, EarlyView.
Abstract Purpose The purpose of this study is to investigate the prevalence of myopia and factors associated with the increase of myopia prevalence in Finland between two generations and discuss the reasons why myopia has not increased similarly as in many Asian countries. Methods A questionnaire assessing factors potentially related to myopia was sent

The effect of 1% tropicamide on central corneal thickness and intraocular pressure

African Vision and Eye Health
Background: Dilating the eye with tropicamide may alter the intraocular pressure (IOP) because of an obstruction of the iridocorneal angle, resulting in decreased aqueous outflow drainage.

Prevalence and Pattern of Refractive Errors Among Yanomami Indigenous People in the Brazilian Amazon: A Cross‐Sectional Observational Study

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background Refractive errors are the leading cause of preventable visual impairment worldwide, yet data from isolated Indigenous populations remain virtually absent from the global literature. The Yanomami, one of the largest Indigenous peoples in the Americas with recent and limited contact with non‐Indigenous society, have no prior ...

Randomised Clinical Trial to Evaluate the Efficacy of Acetazolamide for the Treatment of Cystoid Fluid Collections in X‐Linked Retinoschisis: The AXIS Trial

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background This trial aimed to evaluate the efficacy of oral acetazolamide in reducing cystoid fluid collections (CFC) and improving visual function in patients with X‐linked retinoschisis (XLRS). Methods In this investigator‐initiated, single centre, open‐label, randomised controlled trial, XLRS patients aged ≥ 12 years with fovea‐involving ...

Effectiveness of cyclopentolate 1% compared to the combination of cyclopentolate 1%, tropicamide 1%, and phenylephrine 10% in cycloplegic refractive examination

Journal of Clinical Ophthalmology and Research
Context: Refractive errors in children require appropriate eyeglass correction. Cycloplegic refraction is a method used to determine eyeglass prescriptions in children due to their high accommodative power.

Are Ocular Markers of Sun Exposure Associated With Skin Cancer? A Cross‐Sectional Analysis of the Busselton Healthy Ageing Study

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background Higher past sun or ultraviolet radiation exposure increases the risk of skin cancer and three common ocular findings: pterygium, conjunctival ultraviolet autofluorescence (CUVAF) and myopia. We investigated whether ocular markers of past sun exposure are associated with a history of skin cancer.

Zeb2 Controls Retinal Physiological and Pathological Angiogenesis by Regulating Astrocyte Proliferation and Differentiation

Cell Proliferation, EarlyView.
During development, the oxygen‐sensitive transcription factor Zeb2 restrains astrocyte proliferation and maturation to ensure balanced retinal angiogenesis. In disease, it promotes the neurotoxic A1 astrocyte phenotype and inflammation, thereby promoting reparative revascularization over pathological neovascularization.

Cycloplegia Improves the Inter-Optometrist Repeatability of Subjective Refraction

Photonics
Background: Since accommodation may be a source of error affecting the inter-optometrist repeatability of subjective refraction, this study investigated whether the use of cycloplegia could improve this repeatability.

Albumin Levels in Tear Film Modulate the Bioavailability of Medically-Relevant Topical Drugs

Frontiers in Pharmacology, 2020
The breakdown of blood-tear barrier that occurs with ocular pathology allows for large amounts of albumin to leak into the tear fluid. This process likely represents an important restriction to drug absorption in ophthalmology, as only the unbound drug ...
