case_images: Ophthalmological examination results before and after the operation. (A) Frontal view of cornea, there was a circular ulcer (approximately 3 mm in diameter) at the center of the cornea, and the anterior chamber of the left eye was invisible. (B) Slit-lamp examination. The result showed that the corneal epithelium was disappear in ulcer, stromal around the ulcer was edema, and the depth of the ulcer was about 70% of the corneal thickness. (C) Fluorescein sodium staining showed positive. (D) The results of OCT examination showed that the epithelium and endothelium in the ulcer area were missing, part of the stroma and Descemet's membrane bulged, and the reflection of the stroma in the ulcer area was higher, which was suspected to be related to edema. (E) On the 7th day after operation, the conjunctival flap grew well and closely with the corneal ulcer area. The corneal edema area enlarged compared with that before operation. (F) On the 14th days after operation, the new blood vessels extended from the conjunctival flap to the corneal tissue, and the sutures were removed. The edema subsided gradually compared to 7 days after surgery. (G) On the 21st days after operation, the corneal edema subsided completely, and the transparency recovered around the ulcer.

case_images: There was circular ulceration (approximately 3 mm in diameter) at the center of the cornea, and the anterior chamber of the left eye was invisible (Figure 1A). Slit-lamp biomicroscope (Portable Keeler, YZ3, 66 vision-Tech, China) examination showed stromal edema around the ulcer, and the depth of the ulcer reached 70% of the corneal thickness (Figure 1B). Fluorescein sodium staining was positive, and the positive area was consistent with the size of the ulcer (Figure 1C). Descemetocele was found when preparing for optical coherence tomography (OCT; CIRRUS HD-OCT 400, ZEISS, Germany), which was confirmed by the OCT (Figure 1D).
