Paracentral acute middle maculopathy following coronary angiography.

Purpose: To describe a case of paracentral acute middle maculopathy (PAMM) after coronary angiography

Observations: A 65-year-old female patient exhibited a dense central scotoma 5 hrs after coronary angiography. She presented the next day to the retina clinic and received a complete visual examination including slit lamp biomicroscopy, dilated fundus examination, fluorescein angiogram (FA), spectral domain optical coherence tomography (SD-OCT) and OCT-Angiography (OCT-A). She was found to have the characteristic findings of PAMM including a hyperreflective band at the inner nuclear layer (INL) with extension into the inner plexiform layer (IPL) and outer plexiform layer (OPL) on imaging.

Does Prophylactic Oral Zinc Reduce the Risk of Contracting COVID-19?

Objective In this study, we aimed to investigate whether zinc provided in Age-Related Eye Disease Study 2 (AREDS2) vitamins is associated with a decreased risk of contracting coronavirus disease 2019 (COVID-19). Materials and methods We conducted a retrospective observational cohort study involving patients at a retina-only practice who were provided a questionnaire at each visit to assess whether they were symptomatic of or had contracted COVID-19. Those who answered yes to testing positive for COVID-19 were retrospectively analyzed and categorized based on their AREDS2 vitamin use, and a Pearson's chi-squared test was performed.
