Insights

Acute primary angle closure (APAC) cases increased post-COVID-19 restrictions, with younger patients and distinct ocular characteristics observed. Further research is needed to understand COVID-19

Area of Science:

  • Ophthalmology
  • Public Health
  • Infectious Diseases

Background:

  • The COVID-19 pandemic and associated restrictions have been linked to changes in patient presentation for various medical conditions.
  • Acute primary angle closure (APAC) is an ophthalmic emergency that can lead to vision loss if not treated promptly.
  • Previous observations suggested an increase in APAC during the initial COVID-19 outbreak period.

Purpose of the Study:

  • To determine the incidence of APAC during the COVID-19 post-restriction period.
  • To investigate the specific characteristics of patients presenting with APAC after COVID-19 restrictions.
  • To explore potential correlations between COVID-19 infection, symptoms, and APAC development.

Main Methods:

  • Retrospective, multi-center study comparing APAC patients from a post-restriction period (Dec 2022-Jan 2023) with a control period (Dec 2021-Jan 2022).
  • Analysis of ocular data from electronic medical records for patients with APAC.
  • Questionnaire-based data collection on COVID-19 symptoms, treatments, lifestyle, and emotional state during the post-restriction period.

Main Results:

  • A significant increase in APAC cases was observed during the post-restriction period (189 patients) compared to the control period (51 patients).
  • Patients in the post-restriction period were younger and exhibited shorter axial length, larger pupils, and more advanced glaucomatous changes.
  • Among patients with concurrent COVID-19, coughing/vomiting were common symptoms, with reduced outdoor activity, increased water intake, antipyretic use, and mood swings reported.

Conclusions:

  • The study confirms a notable rise in APAC cases with specific demographic and ocular features following COVID-19 restrictions.
  • The findings suggest a potential link between COVID-19 infection, its symptoms (e.g., coughing, vomiting), and behavioral changes with APAC.
  • Further investigation is warranted to elucidate the causal relationship between COVID-19 and APAC recurrence or onset.

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...

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...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...
