Symptoms of optic neuritis in the affected eye include pain on eye movement, sudden loss of vision, and decrease in color vision (especially reds). Optic neuritis, when combined with the presence of multiple demyelinating white matter brain lesions on MRI, is suspicious for multiple sclerosis .
The symptoms and signs associated with convergence insufficiency are related to prolonged, visually demanding, near-centered tasks. They may include, but are not limited to, diplopia (double vision), asthenopia (eye strain), transient blurred vision, difficulty sustaining near-visual function, abnormal fatigue, headache, and abnormal postural adaptation, among others.
Common causes include welding with failure to use adequate eye protection such as an appropriate welding helmet or welding goggles. This is termed arc eye , while photokeratitis caused by exposure to sunlight reflected from ice and snow, particularly at elevation, is commonly called snow blindness . [ 5 ]
Major symptoms are sudden loss of vision (partial or complete), sudden blurred or "foggy" vision, and; pain on movement of the affected eye. [4] [5] [2]Many patients with optic neuritis may lose some of their color vision in the affected eye (especially red), with colors appearing subtly washed out compared to the other eye.
Symptoms of ocular neuropathic pain can range from devastating, unrelenting eye pain and severe sensitivity to light (photophobia) in the worst cases, to mild hyperalgesia or dysesthesia such as a sensation of dryness, stinging, or foreign body in milder cases. Mild neuropathic pain symptoms can appear similar to clinical symptoms of aqueous ...
Nyctalopia; impaired night vision. Symptoms are not consistent with typical migraine aura. Symptoms are not better explained by another disorder (ophthalmological, drug abuse). Normal ophthalmology tests (best-corrected visual acuity, dilated fundus examination, visual field, and electroretinogram); not caused by previous intake of psychotropic ...
LHON, as the name suggests, is an inherited mutation that results in acute or subacute vision loss, displays incomplete penetrance and predominantly affects young males. Onset is usually between the 2nd and 4th decade of life, and usually presents with rapid vision loss in one eye followed by involvement of the second eye (usually within months).
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.
