Retina
The retina is the only place in the human body that can see tissues or small blood vessels directly; it is therefore an important place where a person can be diagnosed with a disease such as blood pressure, diabetes, certain tumors in the brain For example, the patient’s diabetic retina contains several changes. These changes include the presence of new small blood capillaries, as well as hemorrhage in various forms, retinal formation, fibrosis in the vitreous body, retinal detachment or a person with diabetes The weakness is not simple to consider, and the development of the disease in a coliform And without treatment may lead to a lack of consideration.
The retina is a very thin tissue, located in the back of the eye. Through this retina we can see the details of things from images, bodies, etc. This retina is very sensitive to any change in blood circulation, such as what happens with the elderly, Of blood vessels and arteries that allow oxygen and other nutrients into the retina. These retinal vessels must be in excellent condition, function properly, and if they do not, they may cause loss of vision or disease Retina, there are many diseases that lead to injury Retina, including:
Diabetes and its effect on the retina
- Some diseases that I have referred to in the introduction to the article, such as: retinal bleeding, vitreous cystitis, etc., can be treated if the blood secret is properly controlled, continuously and effectively. To avoid bleeding, and to reduce the symptoms that may appear in the future.
- Changes in the retina due to diabetes may not be treated, but can be halted or worsened, and any new complications can be prevented and mitigated.
Blood pressure and kidney disease and its effect on the retina
When blood pressure rises periodically in the body, kidney infections and pharyngeal poisoning occur, these diseases play a large role in the appearance of retinal diseases. Blood vessels appear in a precise and rigid manner. This leads to bloody retinal rupture, And damage to retinal cells.
Retinal diseases
Obstruction in the retinal vein
This leads to severe bleeding in most parts of the retina, and may lead to sudden loss of vision, and as a result of this obstruction occurs high pressure of the infected eye – black water – and the feeling of a person with severe pain after a time not long – 3 months or more – On eye injury, but when the eye does not respond to the appropriate treatments and medication, and the severity of pain that may suffer from the patient, may eventually lead to the removal of the eye.
Closure of the main artery of the retina
When the main artery of the retina is exposed to a stroke, this artery prevents access to the food material needed for the retina and also prevents the oxygen carried by the blood with it to the retina, which leads to a complete damage or damage in the tissues of the retina, and this can happen in the main artery to Variable changes in blood vessels.
-
- Causes of occlusion
- A narrow carotid artery present in the neck.
- Hypertension in the affected person.
- Diabetes may cause this blockage.
- Some heart diseases.
- Diseases that cause disorder and tightness in the blood vessels.
- This blockage can cause sudden loss of vision and no pain in the eye.
- Expanded in the infected pupil, which does not move normally when highlighted.
- The results of the obstruction: loss of the retina to its clear characteristics, and luster known, to appear yellow stain as a pale red dot appear in the center of the retina, also show the result of this blockage very interesting arteries contain points of blood frozen in sparse, and the optic nerve begins to submerge in some cases, Period of infection.
- Treatment of this obstruction: The treatments used to eliminate this closure is unsuccessful despite the many attempts and the development of drugs, most of the attempts by doctors to treat these cases of eye surgery, to dissolve the impact of the stroke and reduce, did not give satisfactory therapeutic results.
Retinal detachment disease
Retinal detachment is the separation of the pigmented epithelial layer from the inner nervous layer of the retina. This separation occurs for several reasons,
- Floating the retina inward due to the presence of some fluids or infections that are floating.
- Tendency of the retina to the inside due to damage to the vitreous or ciliary membrane.
- A retinal surge may occur due to the presence of a tumor in the retina.
Retinal detachments
Retinal detachment
Information on the cause of this separation is not apparent, but there are research and medical studies that refer to:
- The presence of dynamic movement between the retina and the retina behind the liquid fluid.
- Weakness around the retina due to retinal atrophy.
People at risk:
- Who suffers from severe short sightedness.
- The eye is exposed to a direct injury.
- Family History.
Symptoms of this type:
- High blur and blurring of vision.
- Feeling like there is a moving blur in front of the eye.
- The sensation of bodies floating in front of the eye.
- Changing visible objects and sizes.
- The patient sees flashes of light when the eye moves suddenly.
- Very poor vision.
- Eye pressure is low.
- The red color is seen by the patient as gray.
Treatment of this type of separation: The goal of treatment in this case is to close the network rupture to prevent the leakage of fluids through it, and the following methods:
- Crystalline Installation Method: Laser therapy is defined, which is most common these days especially with extreme technological development.
- Solid Forming Method: Here the edges of the tear are rounded through a piece of plastic that is installed against the place of rip.
Secondary separation
This type is known for its causes, namely:
- The eye is exposed to various injuries, both external and internal.
- Eye injury after a white water procedure.
- There is damage to the glass body.
- The presence of choroid retinal tumors.
Treatment in this type is average, and is available, very effective, and has satisfactory results.
Yellow spot disease
This hole is located in the middle of the center of vision, where a group of black spots are formed in this center, and the vision, especially the vision of detailed objects, such as facial features, reading newspapers, etc., is unclear, but many scientists and doctors refer this to A common cause, which is: the idiopathic, this condition appears on its own and unexplained.
Treatment of the yellow spot: Treatment of these spots with drugs is not possible and there are treatments, such as eradication of glass, and in this process is cleaning glass liquid, and peel the thin sheets that exist in the area of spots, and then clean the eye with gas similar to air, in this process will remain weak vision For weeks, the gas in the eye is removed. This is a very successful science. The vision is improved and the patient has a success rate of 80-90% of the total.
