Insights

This review explores how COVID-19 affects the eyes. Conjunctivitis and keratoconjunctivitis are noted in adults, but more research is needed for children and the elderly.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Public Health

Background:

  • COVID-19, caused by SARS-CoV-2, emerged in December 2019.
  • The World Health Organization officially named the disease COVID-19 in February 2020.
  • As of July 2nd, 2020, over 10.8 million cases and 519,000 deaths were reported globally.

Purpose of the Study:

  • To review the current literature on ocular manifestations of COVID-19.
  • To inform readers about the impact of COVID-19 on the eyes of adults, children, and the elderly.

Main Methods:

  • A comprehensive literature search was conducted using PubMed.
  • The search covered the period from December 2019 to July 2nd, 2020.
  • Included studies were randomized trials, observational studies, case series/reports, and letters concerning confirmed COVID-19 cases.

Main Results:

  • 218 papers were identified since the COVID-19 outbreak.
  • Conjunctivitis and keratoconjunctivitis have been reported in adult COVID-19 patients.
  • Limited data exists regarding ocular effects in pediatric and geriatric populations.

Conclusions:

  • Ocular symptoms like conjunctivitis are associated with COVID-19 in adults.
  • Further research is essential to understand the full spectrum of COVID-19's impact on the eyes in children and the elderly.

Glaucoma: Overview01:25

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
