Description
Summary:The purpose of this case report is to correlate clinical features of granular dystrophy using 820 nm optical coherence tomography (OCT) in order to determine the depth of intrastromal corneal deposits. We report a case of a 38-year-old man with granular dystrophy. After complete ophthalmologic examination the patient was submitted to OCT, using the Stratus OCT III, originally proposed for studying disorders of the posterior segment. Best-corrected visual acuity was 20/50 in both eyes. Biomicroscopy revealed bilateral "snowflake"opacities in different levels of the stromal layer. OCT disclosed multiple hiperreflective dots in anterior and deeper stromal layers. It was possible to assess the morphology of the cornea and to determine the depth of the corneal deposits with serial cross-sectional OCT scans using the Stratus OCT III.
