Eye Disorders and Their Types
Eye disorders are examined in two groups: refractive errors that affect visual acuity and eye diseases. Myopia, hyperopia, and astigmatism are the most common refractive errors. Patients with myopia have blurred distance vision, while hyperopia causes difficulty with near vision. Astigmatism affects both distance and near vision because of irregularities in the cornea. Eye diseases […]

Pupil dilation is medically known as mydriasis. Low light levels, the effects of medication, or certain neurological diseases may cause this condition. It may be normal or pathological. Physiological mydriasis generally occurs in dark environments and is temporary. Drops containing adrenaline and certain medications may produce a similar effect. Pathological dilation may indicate emergencies such […]

Can Amblyopia (Lazy Eye) Be Treated with Excimer Laser?
Amblyopia is not a condition that can be treated directly with an excimer laser. However, the refractive errors that cause amblyopia can be corrected with laser treatment. This may improve visual quality and help the weaker eye to be used more effectively. The most effective methods for treating amblyopia are patching therapy during childhood and […]

What Causes Cataracts at a Young Age?
Cataracts at a young age develop when the natural lens of the eye loses its transparency earlier than normal. They may occur due to congenital, traumatic, or metabolic causes. They can lead to a significant reduction in visual quality. Genetic factors and congenital metabolic diseases may cause cataracts during childhood. In such cases, early surgical […]

What Is Eye Tomography? How Is an OCT Scan Performed?
Eye tomography is an imaging method used to obtain high-resolution cross-sectional images of specific tissues in the eye. In ophthalmology, the term eye tomography usually refers to Optical Coherence Tomography (OCT). OCT is particularly used for the structural evaluation of the retina, macula, and optic nerve head. Its non-contact application and the ability to compare […]
