Follow-ups and treatments can delay the progression of the disease or prevent vision loss, especially if treatment is initiated in the early stages. Depending on the progression of the disease, your treatment options may prescribe eye drops, laser treatment, oral medications, surgery, or a combination of any of these.

Medications for glaucoma include:

  • Eyedrops: It is most likely that your treatment of glaucoma will begin with eye drops. The medications reduce the eye pressure by enhancing the fluid drains from your eye or reducing the amount of fluid your eye makes. Prescription eye drops medications include prostaglandins, beta-blockers, alpha-adrenergic agonists, Rho-kinase inhibitors, cholinergic agents, and carbonic anhydrase inhibitors
  • Oral medications: Oral medications may be prescribed along with eye drops if eye drops do not work to reduce the eye pressure to the required levels. Usually, carbonic anhydrase inhibitors are orally prescribed.
  • Other therapies: Other treatment procedure includes laser therapy and different surgical procedures that aim to improve drainage of the eye, thus lowering the eye pressure

So which foods should be avoided if you have glaucoma and what medications can help?
