AIMS
1. To study change in scar grade over 1 year after corneal ulcer healing.
2. To assess final visual function.
3. To assess subjective need for keratoplasty following corneal ulcer.
METHODS
This study had a prospective and retrospective arm. Corneal scar grading, BCVA, Binocular Visual Field (BVF), Stereopsis and Glare Acuity (GA) was done at recruitment (at healing of epithelial defect), 3rd, 6th and 12th months in the prospective arm and at 1st & 2nd year in the historical arm. Subjective quality of vision (QOV) and desire for keratoplasty was assessed using a questionnaire.
RESULTS
Significant drop in corneal scar grade, and improvement of BCVA at one year following ulcer healing was found. BVF showed slight improvement. GA and stereopsis did not significantly change.
Most patients refused corneal transplant, mainly because QOV was good.
CONCLUSION
A combination of visual outcome variables, not just acuity should be used to determine the outcome following corneal ulcer.
