Loss of vision
Loss of vision can be categorised as follows:
Sudden painful loss of vision
This is sudden loss of vision accompanied by eye pain or headache and should be examined immediately, as it may be due to a site-threatening illness.
The causes of this condition range from inflammation of the retinal arteries and migraine to a pituitary tumour or optic neuritis.
Sudden painless loss of vision
If visual loss occurs abruptly but without pain, the cause is often linked to ischemia – an blockage of the blood vessels that supply the eye. Retinal detachment or age-related macular degeneration can also cause these symptoms.
Gradual loss of vision
A full visual field test and ophthalmic examination is performed to determine the underlying cause of the loss of vision. Depending on the type of vision loss, different treatments are required. In the case of neurological symptoms, an MRI may be required to complete the diagnosis.
Treatment depends on the cause of the vision loss:
Sudden painful loss
- Giant cell arteritis (GCA) – High dose steroids with hospital administration
- Optic Neuritis – Steroid therapy
- Intracranial Hypertension – medication, diet changes or possibly surgery
Sudden painless loss
- Retinal Detachment – Laser surgery, possibly with vitrectomy
- Cerebrovascular Accident – medication with possible surgery
- Vitreous Haemorrhage – Surgery depnding on the type of condition
- Cataract – Minor surger
- Open Angle Glaucoma – Laser Treatment
- Tumours and Inflammation – Surgical Excision
