Steroids and Cross-Linking for Ulcer Treatment Trial II: Baseline Characteristics

Area of Science:

• Ophthalmology
• Infectious Diseases
• Public Health

Background:

• Corneal ulceration is a significant cause of visual impairment, particularly in low and middle-income countries.
• Understanding baseline patient characteristics and ocular comorbidities is crucial for effective treatment strategies.
• The Steroids and Cross-linking for Ulcer Treatment Trial investigates novel treatments for bacterial keratitis.

Purpose of the Study:

• To explore baseline characteristics of patients with smear-positive bacterial ulcers enrolled in a clinical trial.
• To identify ocular comorbidities among patients screened for inclusion in the trial.
• To compare demographic and clinical factors between India and the United States.

Main Methods:

• Descriptive statistics were used to analyze data from 2005 screened patients and 280 enrolled patients.
• Patient data included factors related to infection, ocular comorbidities, and reasons for exclusion.
• Statistical analysis compared baseline characteristics between Indian and US patient populations.

Main Results:

• Patients in India were more frequently associated with agricultural work (47%) and manual labor (19%).
• Patients in the US were predominantly associated with contact lens wear (69%).
• Exclusionary factors for pre-existing blindness, such as cataract and glaucoma, were significantly higher in India (27% and 13%, respectively) compared to the US (0%).

Conclusions:

• Corneal ulceration disproportionately affects populations in low and middle-income countries, necessitating tailored healthcare considerations.
• Baseline factors associated with agricultural work and manual labor in India, contrasted with contact lens wear in the US, underscore geographical disparities.
• Addressing healthcare disparities requires evaluating these distinct baseline factors to improve patient outcomes for infectious keratitis.
