Purpose:
To study the clinical outcomes, time span of healing of various ocular surface disorders with amniotic membrane graft.
Methods:
A total of 41 patients, presenting to cornea clinic were included in the study and divided into five groups depending on the type of diagnosis: Group 1, with either >2 weeks of Persistent epithelial defect following cataract/retinal/glaucoma surgeries or Shield ulcers, Group 2 with >4 weeks of Non healing corneal ulcers, Group 3 with chemical injuries, Group 4 with Epithelial defects following keratoplasty, and Group 5 is the miscellaneous group.
Results:
The mean age of the study subjects was 50.0 years. Overall mean duration between clinical presentation and AMT was 23.59 (30.7) days, a median 16 days (IQR; 2-26 days). Failure rate was high in Group 5 (n = 3: 30.0%) and Group 2 (n = 3: 27.3%). Time taken for epithelial closure was slower in groups 1 and 5 patients. The average time taken for reabsorption of AMG was 14.98 days. The complications included repeat AMG was in four eyes (9.75%), and graft displacement was noted in four eyes (9.75%) required resuturing, three eyes required TPK (7.31%), and one eye underwent evisceration (2.43%) following severe corneal melt secondary to neurotropic ulcer. The mean log MAR visual acuity improved from 1.52 to 1.26 at the 3 months.
Conclusion:
Understanding on timespan for healing of ocular surface disorders with AMG is needed to assess the prognosis of the disease, preoperative counselling for repeat procedures, and the compliance with regard to follow up.
