The patient has approximately 4.00 diopters of regular astigmatism at axis 180 in both eyes. We saw her previously and ruled out keratoconus. Entering vision at todays visit with the left eye wearing her glasses was 20/100 (previously was correctable to 20/20). Her intraocular pressure was 16mmHg. Her cornea was remarkable for severe corneal edema (figure 1).

A peculiar small well delineated region was seen inferiorly on the corneal surface (figure 2). Anterior segment OCT scans were ordered and demonstrated substantial corneal swelling (figure 2). Additionally, a small region of an epithelial detachment was noted in the small delineated region when viewed with the OCT cross section (figure 2).

The unclear clinical picture made a definitive diagnosis difficult. I wondered if something may have inadvertently hit her in the eye (over the contact lens) creating the popping sound and resulting in the corneal edema. The patient was prescribed prednisolone acetate 1% drops every 30 minutes for 4 hours then every hour until she went to bed that evening. She was to continue 1 gtt every hour the following day until she was seen in the office.
When she came into the office, she reported a significant improvement in vision and her eye felt back to normal. Vision with her left eye was 20/20. Her corneal edema had significantly improved as seen on the external photo taken by the OCT (figure 3).

There was a significant improvement in corneal edema as measured by the corneal map functionality (figure 4).

When the corneal cross section from the day before is compared to today’s measurement, the epithelial detachment had also resolved (figure 5).
