Improvement of Amniotic Membrane Method for the Treatment of Corneal Perforation

الملخص EN

In our retrospective study we evaluated the efficacy of an improved amniotic membrane (AM) roll-in filling technique (AMR) combined with multilayer amniotic membrane cover to treat corneal perforation and included 46 cornea perforations ≤ 3 mm in diameter treated with AMR and 20% C3F8 mixed gas filling of the anterior chamber.

Anterior chamber depth, aqueous leakage, bubble maintenance time, and cornea morphology were monitored after each operation.

The mean diameter of corneal perforation was 1.60 ± 0.55 mm (range 0.5–3) and the success rate of the AMR method for corneal perforation reconstruction was 100% after a single operation.

Anterior chamber depth was normally reconstructed without AMR break-off, aqueous leak, or other complications.

The mean time of the C3F8 gas bubble in the anterior chamber was 8.6 ± 2.0 days (range 4–12).

At the last follow-up, all patients’ visual acuity was improved to varying degrees.

The mean follow-up time was 11.0 ± 5.6 months (range 3–36).

The AMR plugging combined with multilayer AM cover is a secure and easy intervention, which led to 100% success in our study.

Various perforations ranging from trauma to infection can be treated with AMR, which is especially practical in those countries where donor cornea availability is limited.
