[PHOTOKERATITIS AS RESULT OF DOMESTIC EXPOSURE TO ULTRAVIOLET-C (UVC) LIGHT].

Abstract

Introduction: During the global outbreak of coronavirus disease 2019 pandemic, people sought ways to disinfect their domestic and public surroundings. One of the sanitation options included the usage of ultraviolet-C (UVC) lamps since UVC radiation has been shown to effectively inactivate the SARS-Coronavirus. UVC radiation may also be effective against the SARS-CoV-2 virus. Here we report four cases of bilateral photokeratitis due to the improper usage of UV lamps during the first outbreak of COVID-19 in Israel.

Methods: We collected 4 case reports from patients who were diagnosed with bilateral photokeratitis due to improper usage of UV lamps in their domestic environment from May to December 2020 during the first outbreak of COVID-19 in Israel.

Results: A total of four patients presented with signs and symptoms of bilateral photokeratitis after exposure to UV lamps.

Discussion: Acute exposure of UVC to the cornea may cause "burns", known as photokeratitis. The signs of photokeratitis usually appear a few hours after the exposure. Precautious steps to educate the population must include using protective eyewear in any exposure to UV light and avoiding the use of germicidal lamps in public locations with exposure to the population.
