Non-perforating deep sclerectomy (EPNP) is an innovative surgical technique used for the treatment of glaucoma, a condition that can damage the optic nerve and lead to vision loss if left untreated. Unlike trabeculectomy, a more aggressive traditional procedure, EPNP offers a less invasive alternative with significant benefits for patients.
Firstly, a drainage pathway is created for the aqueous humor, the fluid that fills the eye and can increase intraocular pressure if present in excess. This is performed without completely perforating the sclera, the white outer layer of the eye, thus minimizing the risk of complications. Additionally, the trabeculodescemet membrane, responsible for the eye’s natural drainage, is left intact, stimulating its function and reducing the need for long-term ocular antihypertensives.
Benefits of Non-Perforating Deep Sclerectomy (EPNP):
- Less Invasive: EPNP does not involve complete perforation of the sclera, resulting in a gentler procedure with less trauma to the eye.
- Rapid Recovery: Patients experience a quicker recovery compared to trabeculectomy, with less pain and discomfort.
- Lower Risk of Complications: EPNP minimizes the risk of postoperative complications such as infections, cataracts, and retinal detachment.
- Preserves Natural Drainage Function: The procedure preserves the trabeculodescemet membrane, stimulating the eye’s natural drainage and reducing reliance on medications.
- Long-Term Effectiveness: Studies show that EPNP can effectively control intraocular pressure in the long term, similar to trabeculectomy.
When is it Used?
Thus, it is considered an ideal therapeutic option for:
- Patients with moderate to severe glaucoma who do not adequately respond to medication treatment.
- Patients with open-angle glaucoma.
- Patients at high risk of complications from trabeculectomy, such as systemic diseases or previous eye surgeries.
