It is a branch of science that deals with common diseases of the eye and nervous system. The visualization of an object is only possible after the image is first detected in the eye center at the back of the brain. Visual pathways from the optic nerve to the visual cortex in the brain where vision is seen and also diseases of the cerebral cortex are is the subject of neuro ophthalmology. It also deals with the harmonious movement of both eyes. Causes of headache due to eye diseases and their differential diagnosis are also covered by neuro-ophthalmology. It evaluates low eyelid assesses complaints such as loss of transient visual loss or double vision in pupil sizes.
Which Disorders are the subject of Neuro-Ophthalmology?
- Size differences of pupils,
- Ocular complaints related to multiple sclerosis (MS),
- Ocular complaints related to myasthenia gravice,
- Colour vision disorders,
- A region that cannot be seen in the visual field,
- Thyroid related eye disease,
- Sudden loss of vision,
- Slow progressive vision loss,
- Temporary vision loss,
- Migraine and similar eye pains,
- Eye complaints due to strokes,
- Facial paralysis and convulsions.
What Are the Symptoms and Prominent Reasons?
Transient loss of vision: a very short period of time to come in a temporal or single eye in the eyes of the eyes or loss of vision may be a symptom of temporary occlusion in one of the vessels leading to the eye or to the brain's vision centre. It should be evaluated urgently. It may be due to problems in the heart valves of young people, advanced blood vessels in the neck or heart vessels. Failure to cure may lead to complete obstruction in the vessel and thus permanent loss of vision.
- Sudden vision loss: is medical emergency. One of the veins leading to the eye or the brain's visual centre may indicate constriction or obstruction. The ophthalmologist must be seen within a few hours. Sometimes it may be due to diseases that cause conduction disorders in the nerves, not the vessels.
- Slowly progressive loss of vision: Slowly progressive loss of vision due to intraocular causes such as cataract, glaucoma, macular degeneration may be a cause of life-threatening causes, which in rare cases may cause pressure on the eye nerve in the brain.
- Diplopia: If there is an unbalanced work in the muscles that move the eyes due to a problem in the nerves or muscles running the muscles, the eyes may not be in parallel with each other, and when both eyes send different messages to the brain, there is a diplopia. You must examined by the ophthalmologist as soon as possible, you need to understand what the cause is. Neurological diseases should be investigated and treated if the nerves are related to the brain. If the blood vessel is caused, the condition in the brain and the causes in the heart should be examined and treated. The treatment should be planned with neurology, if there is a muscle disease that may affect other muscles in the body, and with endocrine doctors if there is a problem in the eye muscles due to hormone diseases.
- Open or fall on the eyelid: If there is an unbalanced operation in the muscles that move the eyes due to a problem with the nerves or muscles running the eyelids, there may be a fall or opening in one or both of the eyelids. While opening is more common in goiter disease, falling may be due to muscle diseases or enlargement of brain vessels. Since enlargement of the brain vessels is a life-threatening condition, especially when there is a fall in one of the caps and especially in the case of enlargement of pupil in that eye, a physician must be consulted immediately.
- Inequality in pupils: The difference between the size of the pupils is actually a natural condition. But when this difference is large, or when the difference in light or dark environments is getting large, it may also indicate a major problem with the neck or brain vessels or a significant lung disease. Immediately consulting a ophthalmologist may be life-saving.
- Accident and impacts: The muscles or nerves of the eyelids, the eye muscles themselves or nerves may be injured. Accidents and impacts that may not be obvious to the person in the early period, early diagnosis and treatment may only be provided by the ophthalmologist.
