Megalocornea: Understanding and Characteristics of the Giant Cornea

Megalocornea, also known as macrocornea or giant cornea, is a rare genetic disorder that is characterized by an unusually large size of the cornea of ​​the eye. This condition causes the diameter of the cornea to increase beyond normal values, which can lead to various ophthalmic problems and visual disturbances.

Megalocornea is usually detected in childhood, although in some cases it may not appear until adulthood. The size of the cornea can vary from moderate enlargement to significant deformation of the eye. Typically, the diameter of the cornea is greater than 13 mm, while the normal diameter is around 11-12 mm. Megalocornea can affect one or both eyes.

The reasons for the development of megalocornea are not fully understood, but most cases are associated with heredity and may be associated with mutations in genes responsible for eye development. Some studies indicate a connection between megalocornea and other eye disorders such as glaucoma, cataracts and ametropia.

One of the main symptoms of megalocornea is blurred vision. Patients may experience blurred vision and may have trouble adapting to different lighting conditions. An increased size of the cornea can also affect the shape of the eyeball and lead to astigmatism or other refractive errors.

The diagnosis of megalocornea is usually based on an examination of the eye and measurement of the size of the cornea. Additional tests, such as ultrasound of the eye and genetic tests, may be performed to confirm the diagnosis and identify disorders associated with the condition.

Treatment of megalocornea is aimed at eliminating symptoms and preventing complications. In some cases, contact lenses or glasses with special lenses may be prescribed to correct vision. However, more severe cases may require surgery, including a corneal transplant.

Megalocornia is a rare eye condition that requires close monitoring and care by ophthalmologists. Patients with this disorder should see a specialist regularly and follow their recommendations to maintain eye health and prevent possible complications.

In conclusion, megalocornia is a genetic disorder characterized by an unusually large size of the cornea of ​​the eye. This condition can cause a variety of visual problems and requires close medical supervision. Although the causes of megalocornia are not fully understood, early detection and diagnosis can help determine the best approach to treating and managing the condition. Modern treatments, including contact lenses and surgery, can help patients manage symptoms and improve their quality of life.

Diagnosis of "Megalocornea" and what does it mean? Megalocornia is a serious eye disease that is accompanied by an increase in the size of the cornea. Typically, the size of the cornea in a healthy person is about 6-7 mm in diameter. With megalocorne, it can reach sizes of up to 20 mm or more, which makes it almost opaque and complicates visual function. Treatment for this disease depends on the cause of its occurrence and can be surgical or medical. In this article we will look at the causes, symptoms and treatment of this disease.

Causes

Megalocorrhea occurs in various diseases of the visual organs, such as myopia, farsightedness, astigmatism, cataracts, glaucoma, etc. It can also appear in some conditions not associated with eye diseases, for example, with abdominal tumors or intoxication of the body. Optic nerve damage, stroke, and other diseases can also cause this eye condition. However, megalocorrhea most often affects adults over 35 years of age, as well as patients with increased intraocular pressure. There is also a hereditary predisposition to this disease.

**Symptoms of megalocorrhea**

Symptoms of megalocorrhea vary depending on its form and severity. The most common ones include:

- ***Photophobia*** - patients may feel discomfort from bright light and avoid prolonged exposure to bright rays on the eyes; *Headaches and dizziness* - due to the difficult passage of light impulses through the overly large retina of the eye, headaches occur. There may also be a feeling of fog in the eyes
