[Endoscopically controlled erbium YAG laser goniotomy. Initial preclinical trials]
1Universitäts-Augenklinik Freiburg.
Summary
Endoscopic erbium-YAG laser treatment offers precise trabecular meshwork microperforations for glaucoma surgery. Preclinical trials show potential for intraocular pressure reduction without thermal damage.
Area of Science:
- Ophthalmology
- Laser Surgery
- Glaucoma Research
Context:
- Glaucoma treatment often involves managing intraocular pressure.
- Conventional laser systems can cause thermal side effects.
- Endoscopic erbium-YAG laser offers a novel, photoablative approach.
Purpose:
- To evaluate the feasibility of endoscopic erbium-YAG laser for trabecular meshwork microperforation.
- To assess the safety and efficacy of this new glaucoma surgical technique in preclinical models.
Summary:
- The Endognost system, combining an endoscope with an erbium-YAG laser, was tested in porcine and human eyes.
- Precise trabecular meshwork micropunctures were achieved using a single pulse mode (10 mJ) without thermal damage.
- Higher energy levels or multiple pulses resulted in damage to Schlemm's canal and thermal side effects.
Impact:
- Endoscopic erbium-YAG laser treatment demonstrates comparable effects to excimer lasers on trabecular tissue.
- This technique holds promise for effective intraocular pressure reduction in glaucoma patients.
- Further research may establish this as a safe and effective glaucoma surgical option.
