Summary

Canaloplasty is a more cost-effective glaucoma treatment than trabeculectomy, requiring less hospitalisation and fewer interventions. This study highlights canaloplasty

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Area of Science:

  • Ophthalmology
  • Surgical Innovation
  • Health Economics

Background:

  • Glaucoma treatment costs are a significant concern in public health systems.
  • New interventions must demonstrate cost-utility alongside safety and efficacy.
  • Diagnosis-related group (DRG) reimbursement models necessitate cost-effectiveness evaluations.

Purpose of the Study:

  • To compare the cost and effort of canaloplasty versus trabeculectomy (TE) for glaucoma treatment.
  • To evaluate the cost-utility of canaloplasty in the context of DRG reimbursement.
  • To analyze resource utilization and patient outcomes for both surgical procedures.

Main Methods:

  • Retrospective, consecutive case series comparing canaloplasty (Group I, 21 eyes) and trabeculectomy with mitomycin C (MMC) and intensive postoperative care (Group II, 48 eyes).

Transcanalicular Diode Laser-assisted Dacryocystorhinostomy for the Treatment of Primary Acquired Nasolacrimal Duct Obstruction

Published on: October 13, 2017

  • Analysis of demography, hospitalisation duration, surgery duration, complications, interventions, and pre/post-operative intraocular pressure (IOP) within 6 months.
  • Cost analysis including hospitalisation expenses and overall treatment costs.

    • Main Results:

    • Canaloplasty patients had shorter hospitalisation (5.3 vs 10.7 days), surgery duration (77 vs 48 min), and fewer follow-up visits (2.8 vs 6).
    • Both procedures effectively lowered IOP (Canaloplasty: 28.75 to 12.8 mmHg; TE: 34.5 to 10.3 mmHg).
    • Canaloplasty required fewer interventions (4 vs 107) and re-admissions (0 vs 11), with lower mean hospitalisation costs (€821.50 vs €1658.50) and overall expenses (€2379.62 vs €2733.61).

    Conclusions:

    • Both canaloplasty and trabeculectomy effectively control intraocular pressure (IOP) in glaucoma patients.
    • Canaloplasty demonstrates superior cost-effectiveness due to shorter hospitalisation, reduced need for interventions, and fewer re-admissions.
    • Trabeculectomy is more resource-intensive, involving longer hospital stays and more frequent postoperative care, making it a costlier and more time-consuming option.
