Visual impairment, also known as vision impairment or vision loss, is a decreased ability to see to a degree that causes problems not fixable by usual means, such as glasses. Some also include those who have a decreased ability to see because they do not have access to glasses or contact lenses. Visual impairment is often defined as a best corrected visual acuity of worse than either 20/40 or 20/60. The term blindness is used for complete or nearly complete vision loss. Visual impairment may cause people difficulties with normal daily activities such as driving, reading, socializing, and walking.
Cause
The most common causes of visual impairment:
- refractive errors (42%)
- cataracts (33%)
- glaucoma (2%)
- age related macular degeneration (1%)
- corneal opacification (1%)
- diabetic retinopathy (1%)
- childhood blindness
- trachoma (1%)
- undetermined (18%)
Glaucoma
Glaucoma is an eye condition that damages your optic nerve. Learn what causes it.
Making Sense of Hypertensive Retinopathy
High blood pressure can damage the retina’s blood vessels and limit the retina’s function. It can also put pressure on the optic nerve.
Cataract
A cataract is a dense, cloudy area that forms in the lens of the eye. It develops slowly and eventually interferes with your vision.
Age-Related Macular Degeneration (AMD)
Macular degeneration is a common eye disorder that causes central vision loss. Learn more about it.
Diabetic Retinopathy
Diabetic retinopathy is a condition that occurs as a result of damaged blood vessels of the retina in people who have diabetes. Diabetic retinopathy can develop whether you have type 1 or type 2 diabetes.8
Retinal Vascular Occlusion
Retinal vascular occlusion occurs when one of the vessels carrying blood to or from your retina becomes blocked or contains a blood clot.
Stroke
A stroke (a “brain attack”) is a medical emergency in which part of the brain is deprived of oxygen. This occurs when an artery that supplies oxygenated blood to the brain becomes damaged and brain cells begin to die.
10. ptic Neuritis
The optic nerve carries visual information from your eye to your brain. Optic neuritis (ON) is when your optic nerve becomes inflamed, causing vision loss.
Strabismus
Strabismus is a disorder in which the eyes do not line up in the same direction. People with strabismus cannot look at the same object or place with both eyes at the same time.
Intracranial Hemorrhages
Intracranial hemorrhage (ICH) is bleeding inside the skull. It is a life-threatening emergency.
Subarachnoid hemorrhage
Subarachnoid hemorrhage (SAH) refers to bleeding within the subarachnoid space, which is the area between your brain and the tissues that cover it.
Brain Aneurysm
An aneurysm in the brain is a weak area in an artery in the brain that bulges out and fills with blood. It can be unpredictable and life-threatening, and can cause extremely serious conditions.
Homoeopathic Approach
Homeopathy is a wonderful method for treating vision loss. If the correct medicine is chosen, croup can resolve very rapidly. As with all homeopathic treatments, the goal is to identify the simillimum, the remedy that most closely matches the patient’s presenting symptoms and mental-emotional state. The power of homeopathy for treating vision loss is out of proportion to the expectation.
