To determine the intrastromal layer of corneal deposits in granular corneal dystrophy (GCD).
Investigative case report.
A 32-year-old woman with bilateral decreased vision because of corneal deposits was examined with cross-sectional scans using optical coherence tomography (OCT).
Visual acuity was 20/100 OU. Multiple confluent gray-white patches with an irregular shape were seen in the corneal stroma, leading to a diffuse opacification. OCT disclosed multiple hyperreflective dots in the anterior and deeper stromal layers.
When severe corneal opacities obscure the clinical differentiation between anterior and deep infiltrates, OCT may determine the layers of the accumulation and select an appropriate surgical procedure.
