What is a common treatment option to manage further vision loss in patients with open-angle glaucoma?

In patients with open-angle glaucoma, the primary goal is to lower intraocular pressure (IOP) to prevent further vision loss. One of the common treatment options in managing this condition is through laser treatment, specifically procedures like selective laser trabeculoplasty (SLT) or argon laser trabeculoplasty (ALT). These laser treatments help to improve the outflow of aqueous humor from the eye, thereby reducing IOP.

Laser treatment is often considered when other methods, such as topical medications (eye drops) or oral medications, may not sufficiently control the IOP or if a patient has difficulty adhering to a drop regimen. By employing laser treatment, clinicians can provide an effective, often minimally invasive option that can either complement other treatments or serve as a primary therapy.

The other responses, while relevant in different contexts, do not primarily address the management of vision loss due to open-angle glaucoma in the same direct manner. Regular eye drops are foundational in initial treatment plans, but they may not be sufficient alone for all patients as the disease progresses. Contact lens fitting is unrelated to glaucoma management and not indicated for preventing vision loss in this context. Oral medications can be used, but they are typically secondary to topical treatments and not as commonly employed as laser therapy
