  2. 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]

  3. Optic neuropathy - Wikipedia

    en.wikipedia.org/wiki/Optic_neuropathy

    Optic neuropathy is damage to the optic nerve from any cause. The optic nerve is a bundle of millions of fibers in the retina that sends visual signals to the brain. Damage and death of these nerve cells, or neurons, leads to characteristic features of optic neuropathy.

  4. Visual pathway lesions - Wikipedia

    en.wikipedia.org/wiki/Visual_pathway_lesions

    Lesions involving the whole optic nerve cause complete blindness on the affected side, that means damage at the right optic nerve causes complete loss of vision in the right eye. [3] Optic neuritis involving external fibers of the optic nerve causes tunnel vision. [4] Optic neuritis involving internal fibers of the optic nerve causes central ...

  5. Blurred vision - Wikipedia

    en.wikipedia.org/wiki/Blurred_vision

    Cataracts: Cloudiness over the eye's lens, cause blurring of vision, halos around lights, and sensitivity to glare. [5] It is also the main cause of blindness worldwide. [2] Glaucoma: Increased intraocular pressure (pressure in the eye) cause progressive optic neuropathy that leads to optic nerve damage, visual field defects and blindness. [6]

  6. Visual impairment - Wikipedia

    en.wikipedia.org/wiki/Visual_impairment

    Glaucoma causes visual field loss as well as severs the optic nerve. [62] Early diagnosis and treatment of glaucoma in patients is imperative because glaucoma is triggered by non-specific levels of IOP. [ 62 ]

  7. Vision disorder - Wikipedia

    en.wikipedia.org/wiki/Vision_disorder

    Such movements can cause irritation and fatigue to the eyes. [9] Glaucoma: occurs when the optic nerve is damaged and can result in irreversible vision loss, with the potential to pass undetected until this damage occurs.

    Principal causes of secondary glaucoma include optic nerve trauma or damage, [2] eye disease, surgery, neovascularization, [3] tumours [4] and use of steroid and sulfa drugs. [2] Risk factors for secondary glaucoma include uveitis, [1] cataract surgery [5] and also intraocular tumours. [5]
