  2. Optic neuropathy - Wikipedia

    en.wikipedia.org/wiki/Optic_neuropathy

    Ischemic optic neuropathies are classified based on the location of the damage and the cause of reduced blood flow if known. [3] Anterior ischemic optic neuropathy (AION) includes diseases that affect the optic nerve head and cause swelling of the optic disc. These diseases often cause sudden rapid visual loss in one eye.

    To minimize the risk of further visual loss in the fellow eye or the same eye, it is essential to reduce the risk factors. Common sense dictates trying to control the cardiovascular risk factors for many reasons, including protection from this happening to the second eye. Sudden vision loss should lead to an ophthalmological consultation.

  4. Diplopia - Wikipedia

    en.wikipedia.org/wiki/Diplopia

    One of the first steps in diagnosing diplopia is often to see whether one of two major classifications may be eliminated. That involves blocking one eye to see which symptoms are evident in each eye alone. Persisting blurry or double vision with one eye closed is classified as monocular diplopia. [15]

  5. Ocular myasthenia - Wikipedia

    en.wikipedia.org/wiki/Ocular_myasthenia

    The most common symptoms are double vision and eyelid drooping , whereas the pupil is always spared. Diplopia occurs when MG affects a single extraocular muscle in one eye, limiting eye movement and leading to double vision when the eye is turned toward the affected muscle.

  6. Oculomotor nerve palsy - Wikipedia

    en.wikipedia.org/wiki/Oculomotor_nerve_palsy

    Oculomotor nerve palsy or oculomotor neuropathy [1] is an eye condition resulting from damage to the third cranial nerve or a branch thereof. As the name suggests, the oculomotor nerve supplies the majority of the muscles controlling eye movements (four of the six extraocular muscles, excluding only the lateral rectus and superior oblique).

  7. Macropsia - Wikipedia

    en.wikipedia.org/wiki/Macropsia

    Dysmetropsia in one eye, a case of aniseikonia, can present with symptoms such as headaches, asthenopia, reading difficulties, depth perception problems, or double vision. [3] The visual distortion can cause uncorrelated images to stimulate corresponding retinal regions simultaneously impairing fusion of the images.

  8. Anisometropia - Wikipedia

    en.wikipedia.org/wiki/Anisometropia

    Anisometropia causes some people to have mild vision problems, or occasionally more serious symptoms like alternating vision or frequent squinting. However, since most people do not show any clear symptoms, the condition usually is found during a routine eye exam. [8] For early detection in preverbal children, photoscreening can be used.

  9. Horror fusionis - Wikipedia

    en.wikipedia.org/wiki/Horror_fusionis

    Horror fusionis is a rare condition and normally appears only in patients who have been treated by means of surgery or other interventions. [2] Attempts to achieve stereoscopic vision, in particular anti-suppression therapy and other orthoptic exercises, may lead to double vision as undesired side effect, in particular also to horror fusionis.
