Eye Diseases/ Ophthalmology
At Eye Diseases Departments of Medical Park Hospitals Group the first step of a routine eye examination is listening the complaints of the patient about visual problem. In a routine eye examination firstly eyebrows, eyelids and looking position of the eyes are observed. Refraction defect of the patient is measured with help of computerized ARM (autorefractometer) and retinoscope. Visual acuity of both eyes with and without eyeglasses is measured. In biomicroscopic examination eyelashes, conjunctiva, cornea and other front segment elements of eye are examined carefully. Then eye tensions are measured.
Images of light and objects reach to the vision point at retina by being refracted at transparent layer (cornea) and lens layer of eye. For a normal eye rays that come from outside provide clear vision after refracted at cornea and lens.
With refraction defect disorders may occur at cornea, lens, retina or optic nerve. Individuals with refraction defect should be examined annually for eye and eye ground.
Most significant manifestations of refraction defects are insufficient vision, pain at eyes and discomfort. Lack of far vision (myopia), lack of near vision (hypermetropia), differences in horizontal or vertical vision of eye (astigmatism) and disorder of near vision due to aging (presbyopia).
There are various alternatives to provide clear vision for people with refraction defects. Refraction defects may be fixed with suitable eyeglasses lens or excimer laser treatment. With eye examination retina decollement, hypertension, brain tumor and manifestations related to various diseases may be defined.
Cataract and Treatment (Facoemulsification)
Cataract is loss of transparency of natural lens present inside of the eye. Its occurrence depends on age at a rate of 90% but may be seen in every age group including babies. Loss of vision without pain, glare or increased light sensitivity, pale or yellowish colour vision, loss of night vision is frequent manifestations of cataract.
Only treatment of cataract is surgery. At our hospitals cataract surgery is performed by FAKO (facoemulsificaiton) method which is the latest developed method at world. Quality and type of the lens put into eye is the major factor that effects success of the surgery. At our hospitals spherically designed Bausch & Lomb brand lenses produced at United States and approved by FDA (United States Health Ministry) are used.
According to the patient's preference near-far oriented (multifocal) in-eye lenses may also be used.
Glaucoma and Treatment (Eye Tension)
Glaucoma occurs as a result of increase in pressure inside the eye because of the insufficient excretion of the fluid of the eye due to structural obstruction of the canals that excrete the fluid. Increased eye pressure gives damage to the optic nerve and causes death of the nerve. Increase of eye tension without any manifestations is a disease that may cause sudden blindness. Blurry vision, severe eye pain, head ache, nausea, vomiting and moiré vision are among signs of glaucoma.
Regular eye examinations done by your doctor is most effective way of identifying glaucoma. Vision loss due to glaucoma is irreversible. Drop treatment, laser surgery (argon laser) and surgical interventions are performed in order to avoid further loss. Analytic methods for evaluating the status of optic nerve are Optical Coherence Tomography (OCT), Nerve Fibber Analyzer (NFA), corneal pachimetry and computerized field of vision.
Pediatric Autorefractometer which is in use at some of our clinics is facilitated the examination of children. Look from meter distance to a disc with light is sufficient for the measurement. Routine examinations are required at newborn, 1 years and 3 years of age. For children who have eye disorders examinations for early diagnosis and treatment is very important.
Spoilage of parallel state of eyes when looking at a point is called strabismus. Causes of strabismus may be neglecting usage of eyeglasses despite necessity, abnormality of muscles that move the eye, congenital and neurologic problems.
Objectives of strabismus treatment are improving vision, fixing head position and double vision, obtaining eye movements and eliminating aesthetical complaints. Strabismus is treated with surgical methods.
Turning of eyelids to inside or outside, fixing of wrinkles around eyes, eliminating bags at lower eyelids, operations of tear canal obstructions, eliminating deformations of eyelids due to congenital, senile or traumatic causes, prosthetic eye and treatment of eye tumors.
