Abstract Details

Purpose:

To evaluate the differences between inflammatory and non-inflammaory peripheral corneal thinning detected by anterior segment high resolution optical coherence tomography (HR-OCT).

Setting:

Bascom Palmer Eye Institute, Miller School of Medicine, Miami, Florida, USA.

Methods:

Retrospective chart review of nine patients with peripheral corneal thinning. Analysis of HR-OCT images and correlations with slit lamp photos and clinical history.

Results:

The HR-OCT images of 4 patients with non-inflammatory peripheral corneal thinning, and 5 patients with thinning in the setting of clinical signs of inflammation (pain, bulbar hyperemia, systemic auto-immune disease) were analyzed. On HR-OCT, a band of intense hypereflectivity was consistently seen under the area of thinning in eyes with clinical features of inflammation whereas this finding was absent in patients with thinning-unrelated inflammation.

Conclusions:

A band of hypereflectivity under the area of thinning was seen in patients with inflammatory but not degenerative peripheral thinning. Further studies are needed to evaluate the utility of HR-OCT in the diagnostic approach of peripheral corneal thinning.
