Purpose

Corneal perforation is a frequent situation in an ophthalmological emergency. • • The amniotic membrane retains its place in their management, by promoting corneal epithelialization using its anti-fibrotic, anti-inflammatory, anti-angiogenic and antimicrobial characteristics. • •The aim of our work is to analyze the structural characteristics of the cornea and the amniotic membrane after its integration into the cornea using OCT-SA.

Setting

CHU Hassan II of Fez , department of ophthalmology

Methods

This is a prospective study covering 37 cases of corneal perforations, deep ulcers or pre-perforation. The OCT-SA was performed before the surgical procedure and after for all patients. The post-operative monitoring parameters were: an examination at the LAF and an OCT-SA, on D2, D7,D14 and D28. The follow-up period was 6 months

Results

Our study reports 37 eyes . The mean age was 48.6 years with a male predominance in 67% of cases. The OCT-SA showed the average thickness of amniotic membrane at D2 , D7, D14 and D28 .

On D28, more than 96% of the patients integrated the membrane into the corneal thickness.

The best visual acuity with correction was greater than 5/10 in 2 patients, after an average follow-up of 6 months.

Conclusion

•The amniotic membrane transplant is the best alternative in the management of corneal perforations and pre-perforative ulcers. Its integration into the corneal thickness is always associated with its re-epithelialization. The OCT-SA is the best examination for better monitoring of the integration of this membrane.
