Purpose: To examine RTVue (Optovue, Inc) optical coherence tomography (OCT) as a method for measuring scleral thickness.
Methods: A prospective, single-center study of eyes with a variety of ocular diseases (no scleral diseases) was performed to image scleral thickness utilizing the RTVue OCT. Repeated measurements of scleral thickness were performed using a line scan 3 mm from the limbus in the inferior nasal and inferior temporal quadrants of each eye. Obtained values were analyzed statistically.
Results: A total of 25 eyes in 14 subjects were measured. An average of 3 measurements per location per eye were taken. The mean scleral thickness 3 mm from the limbus was 654.22 µm. The average standard deviation of the measurements from each location was 30.88 µm. The boundary of the conjunctiva and sclera was easily distinguishable.
Conclusion: The results of this study suggest that RTVue high-resolution OCT is a user-friendly modality for measuring scleral thickness.
