Optometry Exams

Narrow and irregular blood vessels visible in the fundus of the eye are one of the first signs that can indicate high blood pressure.

Usually, when the vision is disturbed and unstable during the day, in addition to this, fever, thirst, weight gain or loss, excessive sweating, etc., can indicate diabetes.

In this case the fat sticks to the walls of the blood vessels and they may change their structure, which can be seen in the retinal examination.Arteriosclerosis, and the blockage of blood vessels caused by fat deposits can cause high blood pressure, heart disease and stroke.

A disease that manifests itself in the turbidity of the intraocular lens, the disease is one of the main causes of vision loss in the western world.
The symptoms are decreased vision, double vision, glare and halos in the field of vision, change in the number of glasses, headache and more.
There are a few kinds of cataract:
Congenital cataract: is a cataract that appears at birth. Cataract due to mature: the lens whitens to the point of liquefaction.
Posterior subcapsular cataract: migration of cells to the posterior shell of the lens, causes glare day and night.
Cortical cataract: appears at an older age in the circumference of the lens, the disorder mainly at night.
Nuclear cataract: the most common type is a senile cataract, which is a physiological clouding that progresses with age.
The main causes of cataracts is Sun exposure, age, heredity, smoking, diabetes, high blood pressure, surgeries, medications, obesity and more.
‍
The treatment for cataract surgery is the removal of the natural lens and the implantation of an artificial lens in its place.

is a group of diseases of high intraocular pressure, due to the inability of the eye to regulate its internal pressure level, changes in pressure cause damage to the optic nerve and visual fields, and in severe cases loss of vision.

An eye disease in which the function of the photoreceptors and the colored epithelium (RPE) in the area of ​​the macula (the center of vision) is damaged. As the disease progresses, the photoreceptors stop working. The common occurrence of the disease is related to age.
The disease is divided into two:
‍
Dry age macular degeneration DRY AMD:
Yellow or white deposits of extracellular material appear in the area of ​​the macula called drusen. The deposits accumulate between the retinal epithelium (RPE) and the salivary membrane which is the inner layer of the retina. A large amount of drusen means a high chance of developing macular degeneration.
This accumulation of drusen causes free radical activity and damage to the retina, there is a loss of photoreceptors and of cells that support photoreceptors.
There is no effective treatment for the disease. In severe cases of dry macular degeneration, regional atrophy appears, in which atrophy of photoreceptors, pigmented epithelium and blood occurs in a large area of ​​the macula.
Most people at this stage have no visual impairment.The accepted preventive measures are antioxidants of various kinds and protection from the sun
‍
Wet macular degeneration WET AMD:
Growth of new blood vessels under the pubis. (CNV - Choroidal Neovascularization). This condition causes in a short time degeneration and loss of vision in the large part of the fobia (which is in the center of the macula).
As a result of the bleeding, scar tissue is formed in the center of vision, causing distortion in the central field of vision. In most cases, the disease manifests itself in a decrease in vision, manifested in the loss of the ability to read, the ability to recognize faces, the ability to read a clock, and functional vision.

Some of the accepted treatments are injections such as Avastin, Lucentis, Aelia, laser treatments, photodynamic therapyIn most cases, we can improve visual acuity with the help of low vision accessories.
