You may qualify if…
- Meet the clinical diagnostic criteria for pigmentary glaucoma, with typical signs of pigment dispersion syndrome, extensive trabecular meshwork pigmentation, pathological intraocular pressure elevation, glaucomatous optic nerve damage, and characteristic visual field defects;
- Underwent primary isolated ab-interno 120° trabeculotomy as the initial surgical treatment;

- Able to complete regular follow-up for at least 6 months postoperatively.
You may not qualify if…
- Patients with exfoliation syndrome, exfoliative glaucoma, or other types of primary or secondary glaucoma;
- Patients with a history of ocular trauma, intraocular surgery, uveitis, severe retinopathy, or other ocular diseases affecting intraocular pressure and visual function assessment;
- Patients who underwent combined procedures such as concurrent cataract surgery or other anti-glaucoma surgeries during the operation;
- Patients with severe systemic diseases, cognitive or psychiatric disorders that prevent cooperation with examinations and follow-up;
