Symptoms as an Indicator of Microbial Keratitis Severity and Its Association With Visual Acuity.

ABSTRACT:

Objective

Microbial keratitis (MK) is a vision-threatening and often painful corneal infection. This study aims to quantify severity of symptoms of MK at presentation and investigate their association with visual acuity (VA).

Methods

The Automated Quantitative Ulcer Analysis (AQUA) study recruited MK patients from two sites (University of Michigan and Aravind Eye Care System). At presentation, best-corrected VA was recorded. Patients were surveyed on severity of symptoms on a five-point scale for pain or a four-point scale for redness, light sensitivity/glare, and blurry vision. The association between symptom severity and VA was tested with Spearman correlations (r) and Kruskal-Wallis tests.

Results

Seven hundred three patients with MK were enrolled in the AQUA study
