ISEC notes that glaucoma is commonly managed initially with eye drops to reduce intraocular pressure, with treatment and follow-up often requiring long-term monitoring. ISEC Malaysia
Laser Treatment for Glaucoma
Depending on the type and severity of glaucoma, laser treatment may include:
- Laser peripheral iridotomy for angle-closure glaucoma
- Laser trabeculoplasty for suitable open-angle glaucoma
- Cyclophotocoagulation for selected advanced glaucoma cases
These are established glaucoma treatment modalities described by ISEC. ISEC Malaysia
Glaucoma Surgery
For patients whose glaucoma cannot be adequately controlled with medication or laser treatment, surgical options may include:
- Trabeculectomy
- Glaucoma drainage device implantation
- Other glaucoma surgical procedures according to individual clinical indications
ISEC explains that glaucoma surgery is intended primarily to lower intraocular pressure and preserve remaining vision, rather than restore vision already lost from glaucoma. ISEC Malaysia
