Occipital neuralgia is caused by damage to the occipital nerves, which can arise from trauma (usually concussive or cervical), physical stress on the nerve, repetitive neck contraction, flexion or extension, and/or as a result of medical complications (such as osteochondroma, a benign bone tumour).
The blurred vision usually resolves within 10 weeks but individuals are often left with less vivid color vision, especially red, in the affected eye. [citation needed] A systemic intravenous treatment with corticosteroids may quicken the healing of the optic nerve, prevent complete loss of vision and delay the onset of other symptoms. [citation ...
The visual changes in PRES may include hemianopsia (inability to see the left or right part of the visual field), blurred vision, lack of visual awareness on one side, visual hallucinations, and cortical blindness. [1] Seizures occur in about two thirds of cases with seizures being the initial symptom in about 50% of cases.
Problems with balance can occur when there is a disruption in any of the vestibular, visual, or proprioceptive systems. Abnormalities in balance function may indicate a wide range of pathologies from causes like inner ear disorders, low blood pressure, brain tumors, and brain injury including stroke. [citation needed]
The main symptom is loss of vision, with colors appearing subtly washed out in the affected eye. A pale disc is characteristic of long-standing optic neuropathy. In many cases, only one eye is affected and a person may not be aware of the loss of color vision until the examiner asks them to cover the healthy eye.
Cluster headache is a neurological disorder characterized by recurrent severe headaches on one side of the head, typically around the eye(s). [1] There is often accompanying eye watering, nasal congestion, or swelling around the eye on the affected side. [1] These symptoms typically last 15 minutes to 3 hours. [2]
Some glaucomas (e.g. open angle glaucoma) cause gradual loss of vision and some others (e.g. angle closure glaucoma) cause sudden loss of vision. [6] It is one of the leading cause of blindness worldwide. [2] Diabetes: Poorly controlled blood sugar can lead to temporary swelling of the lens of the eye, resulting in blurred vision. While it ...
The atrophy is progressive; early symptoms include difficulty reading, blurred vision, light sensitivity, issues with depth perception, and trouble navigating through space. [9] [10] Additional symptoms include apraxia, a disorder of movement planning, alexia, an impaired ability to read, and visual agnosia, an object recognition disorder. [11]
