The eyes are the mirror of the soul in them because it says that if someone is sad, happy, tired or angry, but out of them can learn a lot about the general health condition. Sometimes the changes are so obvious and disorders that are seen with the naked eye, but most are nonetheless reveals detailed fundus examination.
Damage to the optic nerve are irreparably and it is very important to time to identify the cause
- Back of the eye (fundus oculi) is the inner part of the eye behind the lens. Fundus examination includes a review of the vitreous body, papillae (the beginning of the optic nerve), blood vessels, retina, macula (yellow spot) and the periphery of the retina (retina). It is very reliable in detecting changes in the eye and disorders in the body - says Sladjana Delević, an ophthalmologist and medical director of the Hospital of Ophthalmology "oculus".
Blood vessels in sight
The back of the eye, the doctor explains, is very complex because of it, except the optic nerve, and a yellow stain, also known as a point of clear vision. It allows us to read, write and see clearly that the specific items that look. Around it are other nerve cells that allow the peripheral vision.
On the retina there is a network of blood vessels that feed the retina. These are the only vessels in the body that can be observed without Doppler, contrast, or non-invasive examinations.
- Because of the complex structure of the fundus examination allows the physician not only insight into diseases of the eye but also in overall health of the body - says Sladjana Delevic.
Changes are easy to observe
Examination revealed optic nerve damage that can result from glaucoma (intraocular pressure), neurologic diseases such as multiplaskleroza, injury, brain tumor, changes in the orbit and the other surrounding structures. Damage to the optic nerve are irreversible, so it is very important to time to identify the cause.
After 40 The preventive check-ups should be done annually. If you are at risk, the review should go more often
However, review of the yellow spot is very important to assess vision. If there is damage to the yellow spot, there is a weakening or loss of central vision, and they should be suspected if the reading of the text appear in the middle holes, waves and curves.
Damage to the yellow spots can be congenital or acquired due to age. In order to prevent these degenerative changes, some ophthalmologists recommend taking vitamin supplements, while the change of use of existing treatment drugs.
Fundus examination may examine the condition of blood vessels of the retina. If the ocular arteries and veins has some damage, should be thoroughly investigated and other blood vessels in the body because it is likely that they are in poor condition.
Damage to blood vessels caused by diabetes, hypertension and atherosclerotic diseases are the result of high levels of cholesterol and other lipids.
Prohibited driving after a review
- To be done by fundus examination, the pupil should be well spread, and this is instillation of the drops.Then the doctor looks a microscope back of the eye using special magnifying glass that allows him to see every detail. If necessary, the doctor will suggest additional diagnostic examinations - Delevic says.
Fortunately, the apparatus used to make three-dimensional images of the optic nerve or macular (HRT and OCT) to enable early detection of the tiniest of changes. In some cases it is necessary to capture and use of contrast substance to determine the state of retinal blood vessels (fluorescein angiography).
Fundus examination is not painful or unpleasant, and patients complain only of the brightness and blurred vision due to large pupil. After a review of recommended wearing sunglasses, and the duration of the effect drops to spread pupils, should avoid driving, reading and writing.
There must be regular checks
Dr Sladjana Delević emphasizes that certain categories of patients must regularly attend examinations intraocular pressure in order to have better insight into their condition. These reviews will point out to them that there has been a worsening of underlying disease, as well as advanced degenerative changes in the eye.
First People with diabetes. The illness lasts longer, more frequent examinations.
Second Patients with hypertension, especially those whose blood pressure is not stable.
Third People with medium and high myopia with them because there is a thinning and cracking of the retina.
4th Patients suffering from glaucoma, elevated intraocular pressure.
5th All men older than 50 years - prevention.
