Correlation of Corneal Ulcer Parameters Using Slit Lamp Evaluation and Anterior Segment Optical Coherence Tomography (Code-T0105)

Introduction: Corneal ulcers are a significant cause of visual impairment globally, requiring precise evaluation to guide effective management. Traditional slit lamp examination is the cornerstone of diagnosis, but anterior segment optical coherence tomography (AS-OCT) provides detailed imaging of corneal structures, offering potential advantages in the assessment of ulcer parameters. This study investigates the correlation between corneal ulcer parameters measured using slit lamp evaluation and AS-OCT to enhance diagnostic precision and treatment planning.

Aim and Objectives:

Aim:

To study the correlation between corneal ulcer parameters measured using slit lamp evaluation and anterior segment optical coherence tomography.

Objectives:

1. To measure corneal ulcer parameters using slit lamp examination and anterior segment optical coherence tomography.
2. Determine the correlation between corneal ulcer size and depth as measured by slit lamp examination and anterior segment OCT.

Methods: This prospective observational study included 100 patients diagnosed with corneal ulcers. Parameters such as size (length, width) and depth were measured using slit lamp biomicroscopy and AS-OCT. Statistical analysis was performed to evaluate the correlation between the two methods.

Results: The study found a strong correlation between slit lamp and AS-OCT measurements for ulcer size (r=0.85) and depth (r=0.82). AS-OCT provided additional clarity in measuring stromal involvement and edge delineation, particularly in deep ulcers.

Conclusion: AS-OCT demonstrates high concordance with slit lamp evaluation in assessing corneal ulcer parameters and offers additional insights into ulcer depth and stromal involvement. Incorporating AS-OCT into routine evaluations could enhance the management of corneal ulcers by providing more precise measurements.
