Abstract Details

Purpose:

To describe the efficacy of a new pinhole amniotic membrane placement technique in cases of peripheral epithelial defects in patients with a single eye or low vision in the contralateral eye.

Setting:

Tertiary referral hospital Fundación Jiménez Díaz Madrid.

Methods:

We present three clinical cases of pinhole amniotic membrane transplantation. This technique is based on the realization of a small central hole with a dermatological 3 to 4 mm punch (according to pupillary diameter in mesoscopic conditions) and a continuous suture in the perilimbal cornea to fix the amniotic membrane.

Results:

No changes in the visual acuity before and after the surgery were observed. patients were followed clinically and photographically showing a complete re-epithelialization with no need for reinterventions.

Conclusions:

Amniotic membrane transplantation is a very useful option in patients with persistent epithelial defects, however, its use is limited by the subsequent visual acuity. The use of the pinhole amniotic membrane technique allows us to treat peripheral persistent corneal lesions without influencing patients' visual acuity. This new technique may become especially useful in patients with functional single eye of low vision in the contralateral eye.
