Ophthalmological examination


Ophthalmological examination includes a series of vision tests that are performed by an ophthalmologist to check the health of the eyes. The ophthalmologist examines different parts of the eye using special devices. We need 1-2 hours for a complete eye examination. By using ophthalmological examinations, diseases of the eyes and visual system are diagnosed and treated in the early stages. Periodic eye examinations should be done to take care of the eyes.

During a complete ophthalmology examination, the doctor does more than simply prescribe glasses or contact lenses. During these examinations, your eyes will be checked for common eye diseases and whether the two eyes work in harmony with each other, and based on the examination of your eyes, there may be diseases such as diabetes, blood pressure, tumors, brain diseases and other diseases in other parts of your body.

 

 


Symptoms of eye diseases


Eye diseases and disorders may cause symptoms that are common to different diseases. As an example, many diseases such as cataracts, destruction of the macular retina due to old age, the formation of a curtain on the macular, opacity of the cornea and many other eye diseases can cause blurred vision, which after examination and full investigation of the main cause will be recognized.
In order to accurately diagnose diseases and disorders of the eye and visual system, you must undergo a complete ophthalmological examination by an ophthalmologist. Eye injuries, sudden changes or loss of vision, and eye pain can be signs of serious problems that require immediate attention. If you have eye or vision symptoms, call your eye doctor. Always consult your doctor about your health and seek treatment if you have any concerns about your eyes or vision.

 


Vision test


In the vision test, the ophthalmologist measures your vision in comparison to people with normal vision using a vision chart. Doing this test actually means how well your eyes see, or in other words, it tests your clarity and vision power. The first test that you will encounter during eye examinations is seeing a vision chart that includes letters in different sizes. First, you must stand at a distance of 6 meters from this chart. You will be asked to identify the direction of the letters that are gradually getting smaller. The smallest row that can be seen by your eyes will be the amount of vision of your eyes. If the eye doctor reports your vision as 20/20, the meaning of this sentence is that you can see the smallest line that a person with normal vision can see from a distance of 6 meters, and if your vision is reported as 20/10, it means that you From a distance of 3 meters, you can see the smallest row that a person with normal vision can see from a distance of 6 meters.

 


Refractive Errors


Refractive error is a very common eye disorder. This problem occurs when the refractive components of the eye, i.e. the cornea and the lens of the eye, cannot accurately focus the images of the outside world on the retina. The result of refractive errors is blurred vision, which is sometimes so severe that it causes vision impairment. Refractive defects cannot be prevented, but they are diagnosed with an Ophthalmological examination and treated with corrective glasses, contact lenses, or refractive surgery. 

 


Common types of refractive errors 

 


- Myopia: Difficulty in seeing distant objects clearly
- Hyperopia: Difficulty in seeing close objects clearly
Astigmatism: skewed vision caused by irregular curvature of the cornea
Presbyopia (which occurs due to a decrease in the matching power of the lens of the eye and occurs at the age of over 40. Presbyopia leads to difficulty in reading or seeing close objects. It is related to aging and happens to almost everyone).

 


Eye discharge


Your eyes produce mucus throughout the day, but a thin and continuous layer of tears washes your eyes. When you are sleeping and not blinking, eye secretions accumulate in the corners of the eyes and sometimes along the lash line. A small amount of discharge upon awakening is normal, but excessive eye discharge, especially if it is green or yellow in color and accompanied by blurred vision, sensitivity to light, or eye pain, can indicate a serious eye infection or disease and you should be examined by an ophthalmologist immediately.
