Corneal Dystrophy Regional Ecstatic

Corneal marginal ectatic dystrophy (Dystrophia corneae marginalis ectatica) is a rare eye disease that is characterized by gradual thinning and protrusion of the peripheral part of the cornea. This leads to a change in its shape, disruption of light refraction and the appearance of astigmatism.

The cause of the development of marginal ectatic corneal dystrophy is a violation of the structure of collagen fibers in the cornea, which provide its strength and elasticity. This may be due to heredity, injury or infection of the eye.

Symptoms of marginal ectatic corneal dystrophy may include gradual deterioration of vision, double vision, a feeling of irritation and dryness of the eyes, and a feeling of eye fatigue when reading or working on a computer. In more severe cases, the cornea may fall out and become twisted, which can lead to serious complications including infections and cataracts.

Diagnosis of marginal ectatic corneal dystrophy involves examining the eye, measuring vision, and studying the shape and thickness of the cornea using special instruments such as a topograph and a pentacamera. A corneal biopsy may be required to confirm the diagnosis.

Treatment for marginal ectatic corneal dystrophy may include wearing special contact lenses that help maintain the shape of the cornea and improve vision. More severe cases may require surgery such as a corneal transplant. In addition, it is important to avoid activities that can damage the cornea, such as contact sports, and monitor your eye health to promptly detect and treat possible complications.

Overall, marginal ectatic corneal dystrophy is a serious eye disease that can lead to significant vision impairment and complications. However, with proper diagnosis and treatment, it is possible to improve the condition of the eyes and maintain the quality of vision for a long time.

Corneal marginal ectatic dystrophy

Corneal marginal ectasia, also known as corneal dystrophy with marginal ectasia, is a rare disease of the cornea that is characterized by progressive widening and thinning of the marginal regions of the cornea. This condition can lead to significant vision loss and even severe corneal weakening, which may require surgery to restore visual function.

Corneal marginal ectatic dystrophy often appears at a young age, although it can also develop in adults. The causes of this disease are not fully understood, but it is believed that genetic factors and abnormalities in the structure of corneal collagen may play a role in its occurrence. Some studies also indicate an association between marginal ectatic corneal dystrophy and certain systemic diseases such as Marfan syndrome and Erler-Danlos syndrome.

The main symptom of marginal ectatic corneal dystrophy is the gradual thinning, protrusion and deformation of the marginal areas of the cornea. This can lead to the development of astigmatism, blurred vision, and a blurred or distorted image. As the disease progresses, the cornea may become so thin and weakened that it is at risk of sagging or rupturing.

The diagnosis of marginal ectatic corneal dystrophy is usually based on an ophthalmological examination, including visual examination, as well as special tests such as corneal topography and pachymetry (measurement of corneal thickness). Biomicroscopy can be used to evaluate the structure and condition of the cornea.

When treating marginal ectatic corneal dystrophy, the main goals are the preservation and restoration of visual function. In the early stages of the disease, contact lenses or glasses that correct astigmatism may be helpful. However, in case of progression of dystrophy and significant loss of vision, surgical intervention may be required.

Various surgical treatment methods can be used depending on the extent and nature of the corneal damage. A corneal transplant may be necessary in cases where the cornea becomes too weakened or destroyed. In some cases, implantation keratoplasty or other surgical methods may be recommended to help strengthen and restore the structure of the cornea.

It is important to note that marginal ectatic corneal dystrophy is a chronic disease, and surgical treatment cannot always completely restore vision. Therefore, regular follow-up with an ophthalmologist and adherence to corneal care recommendations are important aspects of managing this condition.

In conclusion, marginal ectatic corneal dystrophy is a rare corneal disorder characterized by progressive widening and thinning of the marginal regions. Diagnosis is based on an ophthalmologic examination, and treatment may include contact lenses, glasses, or surgery. Regular monitoring and adherence to recommendations are important to manage this condition and preserve the patient's visual function.
