Vision Loss

What You Should Know About Vision Loss

Whether you are experiencing a sudden change in vision or have been suffering for years, there are several things that you should know about vision loss. In addition to identifying the symptoms, you should be aware of the causes and treatments.

Signs and symptoms

Whether you are suffering from an eye injury or illness, it’s important to know the signs and symptoms of vision loss. These can be a warning sign of a more serious problem. These problems can include loss of central vision, blind spots, and double images.

If you are experiencing sudden changes in your vision, you should see a doctor right away. These changes can be the first symptom of a serious eye condition, such as retinal detachment.

If you are having problems seeing at night, you may experience photopsia. This can be caused by a recent head injury, or it can be linked to a detached retina. It’s normal to experience this after a movie, but if it happens frequently or at night, it’s a sign of a more serious problem.

You may also experience floaters. These are tiny lines or specks that move around in your vision. They are especially noticeable when you are looking at plain objects. However, floaters that occur too often or in too many places are a sign of a floater-related disease, such as uveitis.

Some types of glaucoma, such as acute glaucoma, can cause rainbow halos. They are a common sign of a glaucoma problem, but they are not a symptom of glaucoma in itself. During a routine eye examination, your doctor will look for signs of glaucoma.

Your eyes can also begin to cloud over, which is a symptom of cataracts. Several vision problems can be corrected with contact lenses or eyeglasses.

If you have lost your vision in one eye, you should see your ophthalmologist immediately. You may have a blockage in the veins in that eye, and it could lead to a bigger stroke later on.


Among the most common causes of vision loss are cataracts, age-related macular degeneration, diabetes, glaucoma, and infections. Some of these conditions are preventable. Other causes of vision loss are reversible. A person with a visual acuity of 20/40 or less is considered to have impaired vision.

Globally, the highest proportion of blindness is due to macular degeneration. It affects more than 15% of people living in high-income regions. The condition results in a decreased sharpness of central vision and is associated with retinal damage.

The incidence of vision loss increases with age. Approximately 8% of people who are aged 65 to 74 have impaired vision. By the time an individual is 75 or older, the incidence of vision impairment increases to 15.2%.

The leading cause of blindness is age-related macular degeneration. The condition occurs in people who are over 50 years old and results in a reduction in the sharpness of central vision. It can also result in a loss of peripheral vision, which can make it difficult for an individual to see objects in the environment.

The condition is caused by high pressure from the fluid within the eye. It affects more than 1.7 million Americans. Often, the first sign of the condition is blurry or cloudy vision. Depending on the extent of the loss, treatment may involve laser photocoagulation or surgery.

Other diseases that can cause vision loss include retinal detachment, optic neuritis, glaucoma, corneal scars, and other injuries. These disorders are often prevented by seeking medical care as soon as possible.

In 2010, the most common causes of vision impairment were uncorrected refractive errors, cataracts, and age-related diseases. The proportion of blindness from each of these diseases was lowest in eastern sub-Saharan Africa and tropical Latin America.


Whether you are experiencing the first signs of vision loss, or you are trying to manage the symptoms, there are a few things you can do to ensure your eye health is up to par.

Performing regular eye exams is a good way to detect the early stages of eye diseases. It can also help you prevent them.

If you do develop an eye disease, there are several treatments available. Some of these therapies may even reverse your vision loss. For example, if you have retinal ganglion cell degeneration, the Argus II artificial vision device might be able to restore your sight.

The retinal ganglion cell is a type of cell that transmits the signal from the photoreceptor to the brain. Argus II works by replacing the lost photoreceptor cells.

A recent study by researchers at the Oklahoma Medical Research Foundation has identified a compound that has the ability to naturally reverse the development of blood vessels. This discovery could lead to therapies for retinopathy, diabetic retinopathy, and other eye conditions.

A Cochrane Collaboration, comprised of a group of doctors and patient advocates, recently reviewed the best available evidence on the topic. The review looked at bevacizumab (Avastin) for its potential to treat macular degeneration.

The University of Toronto Medicine by Design initiative funds a large number of scientists to investigate the causes and cures for eye disease. Some of the findings are encouraging, but researchers are still a long way from successful treatment.

For some patients, an intravitreal stem cell injection might be the most effective treatment. These injections are performed inside the eye and are intended to treat the underlying problem.

The most important thing to remember about these treatments is that they are not cures. They can slow the damage and allow you to have a better quality of life.


Despite the fact that many eye disorders are preventable, there is a considerable economic burden associated with vision loss. In addition, the debilitating nature of vision loss and its impact on productivity and quality of life make the condition a major social problem. Consequently, the economic and social costs of eye disorders are likely to increase in the future as the aging population continues to grow. In this paper, we estimate the economic and social cost of vision loss and eye disorders in the United States.

The economic costs of visual impairment and blindness are estimated using National Health and Nutrition Examination Survey (NHANES) data. The prevalence of visual impairment and blindness among adults is based on autorefractor-corrected near-distance acuity. The incidence and severity of vision impairment and blindness increase with age.

The total excess medical costs were determined using a two-part generalized linear model. The first part is a log-link model that accounts for the double counting of costs for persons with multiple conditions. The second part includes a gamma distribution. For patients with normal vision, the distribution was matched by sex.

The reported subsequent annual medical costs were estimated from patients with diverse follow-up durations. For cases with vision impairment, the proportion of total excess costs from non-eye-related services increased with the progression of the disease.

The direct costs of eye diseases are primarily paid by patients. Approximately 70% of the total economic burden of eye diseases is borne by the patient. This includes medical care, long-term care, and indirect financial costs. These costs include lost earnings due to disability, productivity losses of adults, and transfers from caregivers.

The economic burden of eye disorders and vision loss in the United States is estimated to be $10 billion for people younger than 40 years and $38.2 billion for adults. The federal government pays $13.7 billion annually. This is a significant amount of money, but it is only a small fraction of the total burden of vision problems in the US.
