At What Ages Should An Eye Specialist Examination Be Performed?
An eye examination is required every two years. However, it may be less common in some age groups. Eye examination during infancy is the first meeting with an ophthalmologist.
In the newborn eye examination, the pupils are enlarged and the parts of the eye structure are examined by the physician with the help of some devices. In the second eye examination, a motility test is performed as in newborn babies.
Eye structure and parts are examined. Crushing defects and visual measurements are made to detect crushing defects and laziness.
Tests such as retinoscopy, lea symbols (using symbols instead of letters for vision testing), and random spot stereopsy are used.
The second eye examination should take place between the ages of 3-4. It is important for children to go to an ophthalmologist for 1 or 2 years after the age of 5 for the detection of eye diseases. However, more frequent examinations may be required in children with certain diseases. For example, problems such as strabismus and lazy eye are eye diseases encountered in childhood. These patients need to come for an examination every six months. If the patient has a refractive eye problem, an ophthalmologist examination is recommended once a year.
Although the age range of 3-5 years is critical for the diagnosis of certain diseases such as lazy eye and visual defects in childhood, most eye diseases increase with age. Therefore, with the advancement of age, the frequency of examination should be increased in line with the level of discomfort experienced.
Since some eye diseases such as glaucoma, namely eye pressure, do not show symptoms such as pain, etc., it is important to perform routine controls without interruption. For routine controls, eye doctor examination is required in a minimum amount every 5 years in the age range of 20-39 years, every 3 years in the age range of 40-54 years, and every two years in the age range of 55-64 years over 65 years, especially once a year.
Technologies Used In Ophthalmology Diagnosis and Treatment
Auto-Refractor or automatic refractor is a computer-controlled machine used during an eye exam to provide an objective measurement of the refractive error of the eye, making it a prescription for glasses or contact lenses. Measuring with an autorefractometer is a simple method.
It is obtained by measuring and observing how the light entering a person's eye changes. First, the patient is asked to lean his/her forehead and jaw against the device and look at the picture inside through the hole of the device. The Auto Refractor gives light to the eye by measuring how light changes when reflected from the back of the eye (ocular fundus).
As the reflections are made, it is determined by several measurements when the eye is properly focused. The final figures determine the level of vision correction required.
The most commonly used scanning purpose measurements are the air-puff device. It is done by air-pufftonometry, which is based on sending an air jet to the cornea and repelling it by the cornea. This device is the most sensitive device in eye pressure measurement and the probability of making a mistake is very low compared to the air device.
It is an ultrasonic eye measuring device. It is used to measure the lenses to be placed in the eye after cataract surgery.
It is used to view the eye and its surroundings with an ultrasound device using high frequency sound waves.
Corneal thickness is determined using a pachymetry device before surgical operation and glaucoma treatment with laser.
Field of View
It is determined whether the patient experiences a loss in the visual field with the visual field.
FFA (Eye Angiography)
Fundus fluorescein angiography (FFA) is an examination used to examine the nerve layer and support tissue in the back of the eye, called the choroid and retina. Before the procedure, a drug called fluorescein is injected into a vein in the patient's hand or arm.
It is a device that enables the physician to obtain information about the structure of the cornea before applications such as refractive surgery and lenses.
Iol Master Optical Biometrics
It is a device used to calculate the refractive power of the lens to be inserted in the process of replacing the lens that has lost its transparency in cataract surgeries.
Argon Laser (Retinal Detachment Treatment)
Argon laser is a device used to treat tears and holes. This procedure is a painless procedure. It is a treatment method that is performed by the doctor in the examination room without any pre-treatment and without being anesthetized.
It is a treatment method used for the treatment of bleeding and veins in the retina due to diabetes.
Optical coherence tomography (OCT)
Oct is a device that allows a detailed examination of retinal and choroidal vascularization. With the help of this device, the patient is prepared for an eye examination.
An eye drop may also be instilled to dilate the pupils and facilitate examination. As in FFA, detailed examination of the retinal network is provided without the need for any substance.
OCT is a very important imaging device for the diagnosis of diseases such as glaucoma, eye pressure, retinal diseases, macular degeneration and diabetes mellitus.
Plusoptix is a high-tech screening test used to detect vision defects or eye diseases in children. It is also a second measurement device for patients of all ages.
The excimer laser is applied to the corneal area in the anterior part of the eye. It is a method used to treat visual defects in the cornea, known as the transparent layer in the eye structure.
The procedure, commonly referred to as phaco, is a specially designed cataract surgical instrument. In cataract surgery, the cataract completes the surgical operation by creating a 2 mm incision in the patient's eye. This procedure is done without making the patient sleep and takes approximately 15-20 minutes.
Vitrectomy is a surgery with very few complications and a high success rate, which is often preferred as a surgical operation. It is a procedure used in retinal ruptures, eye diseases caused by diabetes, bleeding, and holes in the eye center.
They are tests used to evaluate retina, brain visual pathways and optic nerve pathways as a whole.
Microperimetry is a visual field test that can take the sensitivity of the retinal tissue with the visual field test and fundus image.
The cornea is the front part of the eye in the form of a transparent layer. It is very important to have a sufficient number of endothelial cells that protect the intact layer of the cornea. Specular microscopy is used to determine the number of these cells that are directly related to corneal transparency.
