What this trial studies

This study aims to develop a non-invasive, rapid diagnostic approach for infectious keratitis by evaluating the influence of TNF-alpha on bacterial pathogens and creating an algorithm to distinguish between different types of keratitis-causing pathogens. It utilizes optical coherence tomography (OCT) and tear cytokine analysis to improve diagnostic accuracy and speed compared to traditional methods. The study addresses the limitations of conventional corneal scraping and bacterial culturing, which can be invasive and time-consuming. By analyzing tear samples, the research seeks to enhance understanding of keratitis and facilitate quicker, targeted treatment options.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 to 119 who present with untreated keratitis within 10 days of symptom onset.

Not a fit: Patients with keratitis symptoms lasting more than 10 days or those with severe medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to faster and more accurate diagnoses of keratitis, improving patient outcomes and treatment efficiency.

How similar studies have performed: Previous small studies have shown promise in using OCT and cytokine analysis for keratitis diagnosis, but this approach is still relatively novel and requires further validation.
