About this trial

This observational study will compare proteomic and elemental profiles of aqueous humor and ocular tissues in patients with primary open-angle glaucoma (POAG) and cataract versus cataract controls without glaucoma. Samples collected during standard surgery will be analyzed using LC-MS/MS and ICP-MS. The goal is to identify glaucoma-associated molecular patterns with potential diagnostic or prognostic relevance.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age ≥ 18 years.

Scheduled for cataract surgery (phacoemulsification with intraocular lens implantation).

Ability to provide written informed consent.

For glaucoma arm: diagnosis of primary open-angle glaucoma (POAG) with coexisting cataract, and planned combined cataract surgery with glaucoma procedure.

Disqualifiers

Age < 18 years.

Pregnancy or breastfeeding.

Advanced visual impairment in the study eye (visual aquity worse than counting fingers).

Any glaucoma type other than primary open-angle glaucoma (e.g., angle-closure, secondary, neovascular glaucoma).

Trial design

Design model

Parallel

Treatments tested in this trial

  • Phacoemulsification With Intraocular Lens Implantation and Deep Sclerectomy

    Procedure/Surgery

    Standard-of-care combined cataract surgery (phacoemulsification with intraocular lens implantation) performed together with deep sclerectomy for glaucoma management. Intraoperative collection of aqueous humor and routinely removed ocular tissues (such as sclera and anterior lens capsule) is performed for research analyses.

    Procedure/Surgery

    Standard-of-care cataract surgery (phacoemulsification with intraocular lens implantation). Intraoperative collection of aqueous humor and routinely removed ocular tissue (anterior lens capsule) is performed for research analyses.
