The eye is placed to a strong headpiece in human body because of it is affected easily from various influences and strikes as sensitiveness and importance. The space holding eye inside it and also being surrounded with bones , is named as orbita(eye hole). It is surrounded with eyebrow and eyebrow bone on the top, temporal bones in outside and at the bottom, and nasal root in inside. Eye lid protects aye from foreign bodies. The volume of eye hole is as 29 cm. It includes eye ball, muscles that move the eye, vesselsand nerves and cushion fatty tissue.Importance of Eye Examination
Our eyes are the first and most important organ that setting learning
and perception capacity in motion and opening the doors of the world
among our organs.
Regular eye examination is one of the most important step will be taken for a healthy life.
Eye Examination Process In Our Hospital
Computerized Eye Examination
With the autorefractometer device which is good for measuring the eye number, whether there are myopia, hyperopia, astigmatism or not in the eye of patient is measured and the best eye-glass numbers are determined. In some cases, especially in children examinations, in order to suppress temporarily adaptability of eye ,an eye drop is dropped to the eyes and autorefractometer measuring is done after waiting for a while. This operation is known as ‘drip examination’ colloquially.
Visual Acuity Examination
Our ability to see fine details is measured with being read of letters, numbers or shapes ordered from capital to small, from a distance. The uncorrected visual acuity is the best vision level that eye has without contact lens, lenticula, or glasses namely as one of the eye is naked.
The corrected visual acuity is the best vision degree can be got by a lenticula or lens are placed to in front of an eye. In lens examination, eye doctor places some lens in front of the eye and determines lens numbers that providing the best and the most comfortable vision to the patient. During this examination the doctor benefits from measurements of autorefractometer device.
Determination of Eye Number
Unclear vision is being formed due to eye refractive error as myopia,
hyperopia, astigmatism in our eyes , bring with it glass need. As a
result of examination, as well as treatment , also it is determined that
which one is ideal option among glasses, contact lens, surgery, or
laser .
Biomicroscobic Examination
Examinating eye without biomicroscop is not possible, because eye
tissue cannot be examined by naked eye without enlarging. In microscopic
examination, structures as covers the front of the eye, eyelashes,
conjunctiva, cornea, sclera, iris, pupil, lens and vitreous are examined
at large with their enlarged forms with the help of special devices.
Intraocular Pressure(High Eye Pressure)Measurement
The best way in diagnosing high eye pressure is regular eye controls. On the purpose of diagnosing high eye pressure, examinations are done with the intraocular pressure measurement device.
Examination of Eyelids
The doctor examines patient’s eyelids’ shape, position, colour, gap between bottom and the top eyelids, closing functions of them., whether there is any swelling, bulk or sensitivity in the eye or not with the help of an object in hisher hand by making patient follow the object without moving hisher head. In this way, functions of muscles which are responsible of movement from right to left, from up to down and to intermediate points are evaluated and it is determined that whether there is any obstruction (bulk, pus, edema etc.)preventing eye movements or not.
Examination of Eye Muscles
Inside muscles of eye, control movements of pupil, and outside muscles of eye provide eyes to stay parallel. In the examinations of swelling and diplopia, situation of eye muscles are determined.
Examination of Eye Ground
With this examination, vitre gel, retina and optic neuro cells in the back part of eye are examined. Diabet, hypertension, hereditary disease etc. are determined by being examined of many principles as the transparency and consistency of the vitreous gel, retinal vessels, wiev of nerve fibers, colour, boundaries, cupping of optic nerve etc. for this examination , special lens and examination technics are used. Before examination, pupil is enlarged by using various eye drops for being seen back part of eye better.
