    en.wikipedia.org/wiki/Lens_induced_glaucomas

    The crystalline lens inside the human eye has been implicated as a causative factor in many forms of glaucoma. Lens induced glaucomas or Lens related glaucomas are either open-angle or closed-angle glaucomas that can occur due to a neglected advanced cataract (cloudiness of the lens) or a dislocated lens. It is a type of secondary glaucoma.

  4. Glaucoma surgery - Wikipedia

    en.wikipedia.org/wiki/Glaucoma_surgery

    Glaucoma is a group of diseases affecting the optic nerve that results in vision loss and is frequently characterized by raised intraocular pressure (IOP). There are many glaucoma surgeries, and variations or combinations of those surgeries, that facilitate the escape of excess aqueous humor from the eye to lower intraocular pressure, and a few that lower IOP by decreasing the production of ...

    Trabeculectomy is the most common invasive glaucoma surgery. It is highly effective in the treatment of advanced glaucoma as demonstrated in major glaucoma studies. [citation needed] Even if a prior trabeculectomy has failed a second trabeculectomy can be performed at a different site. If scarring is the main reason, anti-fibrotic and anti ...

    Iridocorneal angle width: The width of the iridocorneal angle is one factor affecting the drainage of aqueous humour from the eye's anterior chamber.A wide angle allows sufficient drainage of humour through the trabecular meshwork (unless obstructed), whereas a narrow angle may impede the drainage system and leave the patient susceptible to acute angle-closure glaucoma.

  8. Tunnel vision - Wikipedia

    en.wikipedia.org/wiki/Tunnel_vision

    Glaucoma is the leading cause for irreversible blindness globally. [11] Glaucoma usually starts with no symptoms to start losing peripheral vision, and if untreated, it can leads to a complete loss of peripheral vision, which is tunnel vision, and eventually, central vision will be affected leading to complete blindness.

  9. Glaucoma - Wikipedia

    en.wikipedia.org/wiki/Glaucoma

    Glaucoma is a group of eye diseases that can lead to damage of the optic nerve. The optic nerve transmits visual information from the eye to the brain. Glaucoma may cause vision loss if left untreated. It has been called the "silent thief of sight" because the loss of vision usually occurs slowly over a long period of time. [5]
