Pannus may recur after sodium amide eye injury
A 3-year case report documents delayed epithelial healing, repeated fibrovascular tissue growth, and unequal visual recovery following a bilateral chemical burn.
A 23-year-old man sustained severe bilateral ocular injury when a sodium amide container exploded, causing extensive limbal ischemia and corneal opacification.

Corneal epithelial healing was prolonged, taking 2 months in the left eye and an estimated 90 to 143 days in the right eye.
3
Fibrovascular pannus invaded both corneas by 2.75 months and recurred or progressed despite anti-inflammatory treatment and repeated surgical resections.

At 36 months, refraction improved left-eye vision to 20/25, whereas right-eye uncorrected acuity ranged from 20/100 to 20/300 during months 30 to 36.

The single-patient report cannot establish typical outcomes or treatment effects, and healing remained ongoing at 3 years.
