The best corrected visual acuity (BCVA) of the left eye was 20/40; slit lamp examination revealed total corneal and 75% conjunctival epithelial loss, corneal haze, and limbal ischemia for nine clock hours (Figure 1 (Fig. 1)).
(A,B): Total conjunctival and two third of the corneal epithelial healing, a week after the RGTA treatment. (C,D): Significant reduction in the size of the epithelial defect, at the end of the second week. (E): Complete healing on the corneal surface with mild irregularity of the peripheral corneal epithelium, on day 20. (F): A month after the complete healing, approximately 300o conjunctivalization is seen at the peripheral cornea.

Within the first week of the treatment, the total conjunctival surface and two thirds of the corneal epithelium healed (Figure 2A,B (Fig. 2)). Following the first week, the topical dexamethasone dose was reduced twice a day and the corneal epithelial defect shrank to a size of 1.5x2.0 mm (Figure 2C,D (Fig. 2)) at the end of the second week. On day 20, the corneal re-epithelialization was completed totally (Figure 2E (Fig. 2)) and the BCVA increased to 20/20. Within a month, approximately 300 degree conjunctivalization occurred on the peripheral cornea (Figure 2F (Fig. 2)).
