Opacity of the lens in the eye in patients with diabetes.. blurry vision, light sensitivity, and difficulty seeing at night

Diabetes and Opacity of the Eye Lens: Understanding Cataracts

Diabetes can indeed increase the risk of developing opacities in the eye lens, commonly called cataracts. These opacities cause blurry vision, light sensitivity, and difficulty seeing at night. While the statement about "white water due to hardening of the arteries" needs clarification, let's explore the connection between diabetes and cataracts in more detail:

1. Increased Cataract Risk:

- Hyperglycemia:

Elevated blood sugar levels associated with diabetes are thought to contribute to cataract formation through various mechanisms, including oxidative stress and protein glycation.

- Metabolic changes:

Diabetes can also alter metabolism within the lens, leading to the accumulation of abnormal proteins and opacification.

- Genetic factors:

Genetic susceptibility may play a role in how individuals with diabetes develop cataracts.

2. Types of Cataracts:

- Nuclear cataracts:

These affect the central part of the lens, often developing first in diabetes and causing blurry vision.

- Cortical cataracts:

These appear as white streaks or wedges in the lens cortex, potentially causing light sensitivity and glare.

- Posterior subcapsular cataracts:

These develop near the back of the lens and can progress quickly, significantly impacting vision.

3. Important Clarifications:

- "White water" description:

This is not a standard medical term for cataracts. Opacities can appear white, but describing them as "white water" might not be accurate in all cases.

- Eye lens blood supply:

The lens itself is avascular, meaning it lacks blood vessels and receives nutrients from surrounding fluids. Therefore, "hardening of arteries" in the lens wouldn't directly cause cataracts. However, diabetes can affect blood vessels throughout the body, including those supplying the eye, and these changes may indirectly contribute to cataract development.

4. Management and Treatment:

- Early detection:

Regular eye exams are crucial for timely diagnosis and monitoring of cataracts.

- Treatment options:

When cataracts significantly impact vision, surgery is the only effective treatment. This involves removing the cloudy lens and replacing it with an artificial lens.

5. Conclusion:

Diabetes can increase the risk of developing cataracts, and awareness of the signs and symptoms is important for individuals with diabetes. Regular eye exams are crucial for early detection and management of cataracts to preserve vision. While the statement about "white water" and arteries needs clarification, the connection between diabetes and cataract formation is well-established.

Remember:

For specific medical advice and diagnosis, always consult with a qualified ophthalmologist. They can provide tailored information and guide you towards the best treatment options for your individual needs.

An ambulatory care nurse is providing instructions to a client who underwent a laser trabeculoplasty for the treatment of primary open-angle glaucoma.. I need to avoid activities that cause straining

An ambulatory care nurse is providing instructions to a client who underwent a laser trabeculoplasty for the treatment of primary open-angle glaucoma.
Which statement, if made by the client, would indicate an understanding of the postprocedure instructions?

a- I should resume the vision that I lost within 1 week.

b- I'm so glad that I had this type of surgery because I can resume all my activities immediately.

c- I need to avoid activities that cause straining.***

d- I may lift objects as long as they do not weigh more than 35 pounds.

To protect your eyes from diabetic retinopathy

1 - Be sure to visit eye specialist or consultant each year.
2 - Make sure that the level of sugar in the blood as close as possible to normal.
Blood sugar
Required level
Fasting
Less than 130 (90 - 130)
Two hours after eating
Less than 180
3 - Make sure that glycated hemoglobin level of less than 7%
4 - Keep your blood pressure is always in the level of 130/80 mm Hg or less.
5 - immediately stop smoking, do not sit in a closed room with no patients.

Diabetes and poor visibility.. The formation of new blood vessels in the retina of the eye and an imbalance in the blood vessels of old

The high percentage of sugar in the blood to exit the fluid outside the body tissues - including the eye lenses, and this process affect the eye's ability to focus. 
But while maintaining the level of sugar in moderate and maintain treatment, vision returns to normal. 
Diabetes leads to the formation of new blood vessels in the retina - the back of the eye - in addition to an imbalance in the blood vessels of old. This situation has caused weakness in consideration in some people. But there are also cases where severe weakness occurs in vision and may end in some cases blindness.

Glaucoma and boils in the diabetic eye eyelid

Glaucoma (Glucoma )
Sometimes causes diabetes to injury situation glaucoma   A high blood pressure inside the eye.
Abscesses in eyelid diabetic
Repeated occurrence of small dimples in the eyelid diabetic compared to healthy persons. This is due to the following reasons:
·  Increase the percentage of sugar in the eye and eyelid tissue, making it a suitable environment for the growth of bacteria.
·  Vulnerability when a diabetic.
· A palace or farsightedness when diabetic.

Retinopathy in a patient with diabetes.. Swelling of the retina competent spot to see the fine details of the picture

Diabetes may lead to an imbalance in the retina. The retina is a thin tissue stuck on the back of the eye sensor captures the image that falls from overseas and converts it to electrical signals up to the brain through the eye to the nerve recognizes and translated. For this Damage in the retina that directly affects the strength of the matter. And usually does not affect the sugar on the retina before the passage of 15-20 years of diabetes.
The defect occurs in the retina of the eye due to damage to the blood vessels, which may result in bleeding inside the retina or in other parts of the eye. Result in bleeding scars in the eye cause low vision, This usually does not cause blindness unless leak blood into the part of the retina known as the macula retina (macula ) Close to the optic nerve. It may happen that grow new blood vessels on the retina and into the vitreous fluid behind the eye. These vessels grow rapidly and ruptures easily and cause vision loss. It is possible that retinal diseases lead to swelling of the retinal macula competent to see the fine details of the images, and the resulting weakening of blindness. 
It should be noted that controlling blood sugar levels is very important to reduce the incidence of complications in the retina, and in the treatment of retinal complications after they occur. In order to detection of the eye on a regular basis by your eye care professional is absolutely imperative.

Diabetes and eye damage.. Vascular damage to the retina. Infection white and blue water

Almost all people with type I diabetes, and 60% of people with type II of the disease happens to them damage in the blood vessels of the retina after 20 years on the disease. May also cause diabetes incidence of white water and the patient more susceptible to glaucoma. 
Most of the symptoms that occur to be simple eye, but may also occur serious problems in some cases.

Diabetes and eye.. Disruption of the blood vessels in the retina

Approximately 50% of diabetics have affected their eyes at one time and weakens their eyes.
Diabetes leads to an equivalent of 12,000 to 24,000 new cases of blindness annually. The main cause of diabetes first new cases of blindness in adults aged 20 to 74 years. One of the most common problems in the eye of a patient with diabetic retinopathy is retinopathy , Which is about an imbalance in the blood vessels in the retina. Also, diabetics are more prone to infection بعتامة lens or what is known as Baketarki  Cataract and high blood pressure Inside the eye (Glucoma).
