ABSTRACT Introduction: The SARS-CoV-2 pandemic has been a major challenge for the international scientific community. Since its inception, studies aiming to describe pathophysiological aspects and clinical manifestations of the disease have been conducted, raising hypotheses and confirming possible associations. One aspect of this scientific medical production is the role of the ocular surface as a means of transmission and clinical presentation of viral syndrome. Objectives: To analyze the role of the ocular surface in transmission, pathophysiology, and clinical manifestations of […]

ABSTRACT Objective: To report a case of anterior uveitis caused by Euphorbia milii sap and review all reported cases of keratouveitis related to this species. Methods: A 64-year-old male patient presented with a 10-day history of reduced visual acuity, pain, and photophobia in the left eye after an accidental contact with Euphorbia milii sap. Best-corrected visual acuity was initially 20/200. Upon examination, ciliary injection, mild corneal edema; fine keratic precipitates, and significant anterior chamber reaction. There was no vitritis, and […]

ABSTRACT We present a case of SARS-CoV-2 conjunctivitis in a 55-year-old female patient, with hyperemia and foreign body sensation in both eyes. The eye examination revealed conjunctivitis. She had detectable SARS-CoV-2 by polymerase chain reaction on conjunctival and nasal swabs. She was treated with ciprofloxacin eye drops, corticosteroids and trometamol for 5 days. After the seventh day of evolution, there was a significant improvement in conjunctivitis, and repeated conjunctival swab was negative.

ABSTRACT Objective To verify the prevalence and the main causes of low visual acuity among students, to correct refractive errors with eyewear, and to establish a relation between vision and school performance. Methods This is a cross-sectional, quantitative study of a social action carried out in a public elementary and high school in the city of Araçatuba (SP). Specialized evaluation was indicated to students who presented visual acuity ≤0.7 in one or both eyes, with or without prior optical correction, […]

ABSTRACT Acute ocular hypertension during hemodialysis is a rare event and may lead to interruption of dialytic therapy due to pain. A case of a 70-year-old male patient is reported, who presented recurrent intense unilateral ocular pain episodes during dialysis sessions for increased intraocular pressure.

One hour after initiating dialysis, he presented an excruciating pain on the […]

ABSTRACT Age-related macular degeneration is the most important cause of irreversible vision loss in the elderly and has been considered a severe public health problem. Current treatments have only been successful in delaying the loss of central vision. Due to increased life expectancy, governments and researchers have been challenged to seek more efficient and successful treatments for age-related macular degeneration. Considering its relevance for public health and the need of further research, this article aims to address age-related macular degeneration […]
