Randomized Controlled Trial Multicenter Study
Effect of Vitamin D and ω-3 Fatty Acid Supplementation on Risk of Age-Related Macular Degeneration: An Ancillary Study of the VITAL Randomized Clinical Trial.
Observational studies suggest that higher intake or blood levels of vitamin D and marine ω-3 fatty acids may be associated with lower risks of age-related macular degeneration (AMD). However, evidence from randomized trials is limited. ⋯ Neither vitamin D3 nor marine ω-3 fatty acid supplementation had a significant overall effect on AMD incidence or progression.

Psychological and Ocular Surface State of Ophthalmologists and Ophthalmic Nurses Working With Patients With Coronavirus Disease 2019.
The influence on the psychology and ocular surface of ophthalmologists and ophthalmic nurses in Wuhan, China, during the coronavirus disease 2019 (COVID-19) pandemic is not yet fully understood. ⋯ These findings suggest that ophthalmologists and ophthalmic nurses in Wuhan experienced more anxiety and depression and reported greater ocular surface abnormalities than counterparts outside of Wuhan, but the wide CIs preclude concluding confidently that there were differences.

Assessment of Firework-Related Ocular Injury in the US.
Fireworks are popularly used for recreation but can lead to potentially blinding injuries. Studies quantifying the trend and national prevalence of firework-related ocular injuries are limited. ⋯ These findings support that firework-related ocular injuries range from mild irritation to ruptured globe, and most occur frequently in those who are young, male, and white. Focused preventive methods and regulations may be imperative in decreasing fireworks-related ocular morbidity, namely from bottle rockets and especially near national holidays.

Glaucoma is a common cause of visual impairment in the Veterans Affairs (VA) health care system, but to our knowledge, no data exist concerning tertiary glaucoma care (ie, laser and filtering surgery). ⋯ Disparities exist in the use of tertiary glaucoma services within the VA, and different care delivery models may play a role. Outcomes of glaucoma care for the different models of eye care delivery were not analyzed in this study.

Prevalence and Causes of Unilateral Vision Impairment and Unilateral Blindness in Australia: The National Eye Health Survey.
This study determines the prevalence of unilateral vision impairment (VI) and unilateral blindness to assist in policy formulation for eye health care services. ⋯ Unilateral vision loss is prevalent in indigenous and nonindigenous Australians; however, most cases are avoidable. As those with unilateral vision loss caused by cataract and posterior segment diseases may be at great risk of progressing to bilateral blindness, national blindness prevention programs may benefit from prioritizing examination and treatment of those with unilateral vision loss.
