My eye lids are lowering. Both eyelid mussels are weak & I guess it is hereditary as it was to my mother. Any treatment for this?
1) Is there any type of nystagmus whi h occurs only in dark or in less light? 2) When I go in dark room it is hard for me to keep my eyes study what is reason behind it? 3) Is there any simple test which can accurately and perfectly detect presence of nystagmus?
The spots which occur in the vision are known as eye floaters. One might feel specks of gray and black or cobwebs and strings drifting in the eyes and the same darts away on staring at them directly. The most common cause of eye floaters is age related. This happens when the vitreous & the jelly like substance of the eye becomes very liquid. The fibers within the vitreous clump to form small shadows on the retina. This gives it an appearance of floaters.
Symptoms of eye floaters Include:
- Spots in the vision which appear as knobby or dark specs and strings that are transparent float in the eye
- Spots which move when the eyes are moved and when one tries to look at them these spots quickly move away from the field of vision
- Spots that are noticed most when looking at plain backgrounds like a white wall or blue sky
- Spots which settle and drift put slowly from the vision
Causes of eye floaters are:
- Age-related: The most common cause of eye floaters is the age related changes in the vitreous. Vitreous is a jelly like substance which fills the eyeballs and help it to maintain the round shape. With age the vitreous liquefies partially and this causes it to be pulled away from the interior surface of the eyeball. As the vitreous sags and shrinks, it becomes stringy and clumpy. When the vitreous gets clumpy then small debris block the light which passes through the eye and casts shadows on the retina.
- Inflammation at the back of the eye: The inflammation of the layers of the uvea in the back region of the eye is called posterior uveitis. This can give rise to eye floaters. Posterior uveitis is usually caused by inflammatory disease or infections.
- Bleeding in the eye: Bleeding of the eye in the vitreous can have any cause associated with it. Some might be an injury or the problems of the blood vessel.
- Torn retina: Tearing of the retina occurs when the sagging vitreous applies a pressure on the retina and ends up tearing it. If treatment not given then the retinal tear might lead to the detachment of the retina and accumulation of fluid behind the retina. This causes the retina to separate from the eye. If not treated it might also lead to permanent vision loss.

Even something as small as an eyeball, has multiple parts within it. The retina at the back of the eye ball is responsible for the clarity of vision. The central area of the retina is known as the macula. Macular degeneration is the deterioration of this part of the retina. Macular degeneration is age related and considered an incurable condition. People suffering from macular degeneration experience blurred vision, black spots and may eventually lose central vision while retaining peripheral vision.
There are two types of macular degeneration; wet and dry. The dry form of this disease is more common than its wet form. Of these, the latter causes more serious vision loss. Dry macular degeneration leads to white or yellow deposits on the retina leading to further degeneration. In the wet form of this disease, blood vessels beneath the retina start growing towards the macula and may pull it away from the base when they break or leak fluid.
There are three stages of age related macular degeneration (AMD).
- Early AMD
This is diagnosed by the presence of deposits on the retina. In most cases, ether is no vision loss at this stage but regular check-ups are essential.
- Intermediate AMD
A comprehensive eye exam will show the presence of larger deposits or pigment changes in the retina. At this stage, slight vision loss may be experienced.
- Late AMD
People suffering from late AMD have noticeable vision loss.
Though this disease is linked to aging, the exact triggers for macular degeneration are unknown. It is understood to be a combination of hereditary and environmental factors. The presence of certain genes and their variants has been associated with a number of cases of this disease. Studies also show that caucasions are at the highest risk of suffering from this disease. Depriving cells in the retina of oxygen can also increase a person's risk of contacting this disease. Other risk factors for this disease are obesity, smoking, high blood pressure and a light eye colour. The side effects of certain drugs can also induce this condition.
Macular degeneration is considered to be incurable but certain forms of treatment can improve vision and slow down the rate of deterioration. Treatment prescribed by a doctor depends on stage of the disease and whether it is wet or dry. Studies suggest that a diet rich in omega 3 fatty acids can prevent AMD and lower the risk of its progression.
