OCT stands for “Optical Coherence Tomography” in English. It is a medical imaging technique used to visualize the retina of the eye. OCT, a technology based on the principles of reflection and refraction of light, creates detailed images of the retinal layers. These images play an important role in the diagnosis and treatment of eye diseases. It is especially used in the diagnosis and follow-up of retinal degeneration, diabetic retinopathy and glaucoma.

Specular microscopy is a medical imaging technique used to study corneal endothelial cells. The cornea is the transparent front layer of the eye and plays an important role in visual function. Corneal endothelial cells are located on the inner surface of the cornea and help the cornea to function properly.

Specular microscopy is used to assess the number and structure of corneal endothelial cells, especially before procedures such as corneal transplantation or intraocular surgery. The examination is performed using a specialized microscope called a specular microscope. The specular microscope uses reflected light from the cornea to create detailed images of the endothelial cells.

A diopter is a unit that measures the refractive power of a person’s eyes. This measurement is used to determine a person’s eye defect (myopia, hyperopia or astigmatism). The diopter measure refers to the strength of the beam of light focused by a lens or optical system.

Myopia (short-sightedness): A condition that makes it difficult to see distant objects clearly. In this condition, the eye brings the focal point to a point in front of the retina. Negative diopter numbers are used to correct this condition.

Hyperopia (Farsightedness): A condition that makes it difficult to see nearby objects clearly. In this case, the eye brings the focal point to a point located behind the retina. Positive diopter numbers are used to correct this condition.

Astigmatism: A condition in which the eye refracts irregularly. Cylindrical lenses are often used to correct this condition. The level of astigmatism is expressed in diopters.

During an eye examination, an optometrist or ophthalmologist will test your eyes to identify these refractive errors. As a result of these tests, a specific diopter number is assigned for each eye and correction of the defects with eyeglasses may be recommended.

Pentacam is a device that allows detailed mapping of the anterior segment of the eye. It is especially used to examine the surface properties, thickness and refractive properties of the cornea (the transparent front layer of the eye). Pentacam is an important tool used in cases such as pre- and post-corneal transplantation evaluation, corneal analysis before cataract surgery, and corneal evaluation before laser surgery.

Pentacam provides high accuracy and reliability when creating a three-dimensional map of the cornea. This allows ophthalmologists to better understand the health and structural characteristics of the cornea and determine appropriate treatment plans.

FFA stands for “Fundus Angiography”. This is a medical imaging technique used to examine the blood circulation of the retina and the choriocapillary layer at the back of the eye. FFA plays a particularly important role in the diagnosis and treatment of retinal diseases.

FFA provides invaluable information in diagnosing retinal diseases by showing circulation, leaks or blockages of blood vessels.

Computerized visual field measurement is a test used to assess the extent and quality of a person’s visual field. The visual field refers to the sum of the area that a person can see within their field of view. This test is often used to identify or monitor conditions such as optic nerve diseases, glaucoma, brain damage or tumors.

During this test, the person usually looks at a fixed point. The person looking at the fixed point is asked to perceive lights or objects appearing in various directions. This helps to determine the boundaries of the person’s visual field. Computerized visual field testing is usually done as part of a detailed eye examination. The results provide important information about a person’s eye health.

Pachymetry is a medical procedure that measures the thickness of the cornea layer of the eye. The cornea is a transparent tissue located at the front of the eye and helps the eye refract light. Corneal thickness is an important factor for eye health and visual acuity.

Pachymetry is used to measure corneal thickness, especially before operations such as cataract surgery and laser surgery. It is also important for accurately measuring intraocular pressure. This is because intraocular pressure can vary depending on corneal thickness.

Pachymetry is usually performed with a pachymeter device. This device can measure corneal thickness quickly and precisely without touching the surface of the eye.
