Optic Neuritis is also known as Retrobulbar Neuritis.
Optic neuritis can cause the perception of blurred vision through the affected eye(s). Symptoms may include some, but not necessarily all of the following:
- Blurred or dimmed vision,
- Blind spot at or near center of vision,
- Colours appearing paler than usual,
- Pain when moving or attempting to move the affected eye(s),
- Tenderness of the eye to touch or pressure,
- Severely reduced vision / blindness in the affected eye(s).
Optic neuritis is one of the symptoms of Multiple Sclerosis (MS) but can also occur due to other infections e.g. herpes zoster, or independently of any other symptoms and pass with full recovery of vision as experienced before through the affected eye(s).
The duration of an instance of optic neuritis is likely to depend on the cause - of which there are many possibilities. In some cases optic neuritis may become a recurrent problem, that is - it may appear to have ceased, only to return some time later.
Medical attention is important because optic neuritis may result in serious damage to vision if not treated appropriately.
