Objective

The localisation of intrastromal deposits in granular corneal dystrophy may be difficult to define, as the layer of the deposits may be hard to observe. Optical coherent Tomography (OCT) is a morphometric measurement providing precise infomation on the architecture of the cornea.

Methods

A 32-year-old female with bilateral decreased vision due to corneal deposits was examined with cross-sectional scans using OCT.

Results

Visual acuity was 20/100 OU. On slit lamp biomicroscopy there were mutiple confluent gray-white dots in the anterior and deeper layers of the stroma, leading to a diffuse stromal haze. OCT disclosed multiple hyperreflective deposits in the anterior and deeper portion of corneal stroma. The low-reflective space between them responds to normal cornea lamellae. Due to the deep infiltration a decision for PK was made.

Conclusions

When severe corneal opacities abscure the clinical differentiation between anterior and deep infiltrates, OCT may determine the layers of the accumulation and select an appropriate surgical procedure.
