¿Por qué su hijo no ve claro después de gastar en gafas?

Title: Why Your Child Doesn't See Clearly After Getting Glasses? Author: Health Daily Section. Reviewers: N/A. Commissioner: N/A. Production Information / Organization: N/A.

As the new school season begins in September, children are once again immersed in a busy learning life. However, many parents have recently noticed that their children are experiencing vision problems.

Isn't it true that during the summer vacations they often play with their phones and strain their eyes? With this thought, parents spend a lot of money on buying glasses for their children, but after using them for a while, the children complain that they still cannot see clearly.

At this point, do parents think that their child's nearsightedness has increased again? Don't be careless! There is another possibility: a vision-threatening disease—keratoconus, quietly threatening the eye health of children.

Keratoconus is an eye disease that primarily affects the shape of the cornea. The normal cornea is round, but in keratoconus, the cornea gradually thins and protrudes outward, forming a cone-like structure. This change may lead to blurred or unstable vision, with symptoms including photophobia and distorted vision. The exact cause of keratoconus is not fully understood but may be related to genetic factors, environmental influences, and other health conditions. Treatment methods include wearing special contact lenses, medication, and in severe cases, surgical options such as corneal transplantation.

Keratoconus is a common, non-inflammatory, chronic, progressive disease characterized by localized expansion of the cornea. In simple terms, it is characterized by thinning and protrusion in a cone shape in the central or paracentral area of the cornea.

If we compare the eye to a camera, the cornea would be equivalent to the camera lens, while keratoconus resembles a lens that has suffered distortions and deformations.

Normally, the cornea should have a regular curved shape, but when one suffers from keratoconus, the cornea deforms as if it were a distorted lens, causing light entering the eye not to focus correctly on the retina, resulting in decreased vision and astigmatism.

Keratoconus usually develops between the ages of 10 and 25, a period characterized by significant learning pressure and frequent eye use. It commonly manifests as progressive worsening of myopia or astigmatism, with astigmatism often being high and irregular.

Many children and parents think this is just a normal worsening of myopia, and by frequently changing glasses, they realize that the corrective effect is not good. For example, some children who have just gotten glasses may no longer be able to see the blackboard clearly within a few months, which may very likely be caused by keratoconus.

Keratoconus is an eye disease characterized by the gradual thinning and cone-shaped protrusion of the cornea. While its precise causes are not fully clear, studies suggest that several factors may be associated with the development of keratoconus: 1. Genetic factors: Keratoconus may have a familial tendency, and genetic factors may play a role. 2. Environmental factors: Certain environmental factors, such as excessive rubbing of the eyes (common in individuals with allergic eye conditions), may exacerbate corneal deformation. 3. Biochemical factors: Changes in specific enzymes and proteins in corneal tissue may lead to structural alterations in the cornea. 4. Other diseases: Some systemic diseases, such as Marfan syndrome and other connective tissue disorders, have a certain association with keratoconus. 5. Gender and age: Keratoconus is usually diagnosed in adolescents or young adults, with a slightly higher incidence in males. Understanding these causes can aid early intervention and treatment. If related symptoms are present, it is advisable to seek medical attention promptly.

The cause of keratoconus has not yet been completely clarified, but it may be related to a decrease in the amount of corneal collagen or an abnormal arrangement of collagen fibers, leading to reduced mechanical strength of the cornea and subsequent thinning and protrusion. Genetic factors and allergies may be related to this disease. Additionally, it has been confirmed that harmful habits such as excessive eye rubbing can induce the development of keratoconus.

Therefore, it is advised to avoid rubbing the eyes in daily life and not to sleep on one's stomach to avoid pressure on the eyeball. For rubbing behaviors caused by other eye conditions like allergic conjunctivitis or dry eyes, it is important to actively treat the primary condition.

The signs of keratoconus include the following: 1. Blurred vision: Patients may feel their vision gradually becoming blurred, especially at a distance. 2. Light sensitivity: Increased sensitivity to light, which can cause discomfort or glare in bright conditions. 3. Double vision: The phenomenon of seeing double images, particularly in low light or nighttime conditions. 4. Worsening of myopia or astigmatism: Existing myopia or astigmatism may worsen, leading to further declines in vision. 5. Discomfort in the eyes: Symptoms may include a foreign body sensation, eye fatigue, or dryness. If these symptoms occur, it is advisable to seek medical attention for a detailed examination.

Some individuals may experience acute corneal edema, leading to a sudden sharp decline in vision; while others might progress gradually with subtle vision reduction, which may be confused with nearsightedness or astigmatism.

The treatment methods for keratoconus include the following: 1. Glasses: In the early stages, special contact lenses can be worn to correct vision and help improve visual acuity. 2. Medication: In certain cases, eye drops can be used to alleviate discomfort in the eyes. 3. Corneal cross-linking: This procedure strengthens the corneal structure using light and medication to halt the disease's progression. 4. Intracorneal ring implantation: This involves placing a ring device inside the cornea to help reshape it and improve vision. 5. Corneal transplantation: In cases where the condition is severe and other treatments fail, a corneal transplant may be needed to replace the damaged cornea. The specific treatment plan needs to be determined based on the severity of the patient's condition and individual circumstances. It is advisable to seek assessment and treatment recommendations from a professional ophthalmologist.

In recent years, methods and techniques for the clinical diagnosis of keratoconus have become increasingly comprehensive and systematic, and treatment plans have made innovative advancements.

If the disease is found in an early and stable phase, frame glasses, rigid gas-permeable (RGP) contact lenses, and rigid scleral contact lenses can be used to correct vision and improve visual quality.

If the condition is unstable and continues to progress, keratoconus cross-linking should be performed as soon as possible, provided the cornea meets surgical criteria, with the aim of strengthening the thin cornea and stopping disease progression. In advanced stages, a corneal transplant becomes necessary to save vision.

Experts warn: Parents should pay attention to changes in their children's vision and not attribute the decline in sight solely to myopia. If a child experiences a rapid decline in vision over a short period, abnormal degrees of astigmatism, or if glasses do not correct the vision adequately, it is essential to take the child immediately to a specialized ophthalmological medical institution for a detailed examination to rule out eye diseases such as keratoconus.
