[Trabecular aspiration. A new surgical method for improving chamber angle facility in pseudoexfoliation glaucoma]
1Universitäts-Augenklinik Köln.
Summary
Trabecular aspiration effectively lowered intraocular pressure (IOP) in patients with pseudoexfoliative glaucoma and cataract. This procedure, combined with cataract surgery, significantly reduced the need for glaucoma medications.
Area of Science:
- Ophthalmology
- Glaucoma Research
- Surgical Innovation
Context:
- Pseudoexfoliative glaucoma is characterized by elevated intraocular pressure (IOP) due to trabecular meshwork obstruction.
- Pigment and fibrillous material accumulation in the intertrabecular spaces is the primary cause of IOP elevation in capsular glaucoma.
Purpose:
- To evaluate the clinical efficacy of trabecular aspiration as a novel surgical approach for improving trabecular facility in glaucoma capsulare.
- To assess the IOP-lowering effect and clinical outcomes of trabecular aspiration combined with extracapsular cataract extraction (ECCE).
Summary:
- Trabecular aspiration was performed using a specialized device in 27 eyes prior to ECCE, clearing debris from the anterior chamber angle.
- Postoperatively, IOP significantly decreased from a mean of 31.6 mmHg to 17.2-21 mmHg at various follow-up points up to 12 months.
- The mean daily glaucoma medication score reduced from 3.81 preoperatively to 0.52 at 12 months post-surgery.
Impact:
- Trabecular aspiration demonstrated a clinically relevant IOP reduction of 44% at 12 months post-procedure.
- The combined procedure shows promise in managing pseudoexfoliative glaucoma and cataract, reducing medication dependency.
- This study substantiates the IOP-lowering effect of removing trabecular debris before ECCE in a select patient group.
