Childhood Cataracts

Our eyes are the primary tool for our learning process, mental development, and the bond we establish with our environment from the moment we are born. The first years of life are especially critical, as the brain's visual center (visual cortex) is shaped and the electrical pathways between the eye and the brain are rapidly constructed. Contrary to the common belief that cataracts are an old-age disease, they can also occur in infants and children. If not intervened urgently, they can lead to permanent blindness or deep amblyopia (lazy eye) that lasts a lifetime.

As Ophthalmology Specialist Ayşe Öner and her expert clinical team with high-level surgical experience in pediatric ophthalmology, we offer world-class services in the diagnosis and treatment of childhood cataracts using the most advanced microsurgical methods. By combining Turkey's unshakable infrastructure in health tourism with the power of our fully equipped, JCI-accredited hospitals, we promise families and their little ones from all over the world not just an operation, but a bright future, a stress-free medical journey in VIP comfort, and compassionate health guidance.

What is Childhood Cataract? (Congenital and Developmental Cataract)

In a healthy eye, the "natural intraocular lens" located right behind the iris refracts incoming light rays so they fall clearly onto the retina. To perform this function, the lens must be completely transparent and clear, like clean glass.

Childhood cataract is a condition where this natural lens loses its transparency partially or completely, becoming opaque and taking on a frosted or milky white appearance. If the cataract is present at birth, it is called "Congenital Cataract"; if it appears during the infancy or childhood years following birth, it is called "Developmental Cataract."

When a child develops a cataract, light cannot reach the retina and, consequently, the brain. Because the brain does not receive a clear image from that eye, it learns "not to use" it. In the first months of life (especially between the 6th week and 6th month), the brain's capacity to learn vision is very high. If images do not reach the brain during this period, cellular connections cannot be established, and the eye remains condemned to poor vision even if the most successful surgery is performed later. This condition is called "Deep Amblyopia (Deprivation Amblyopia)." For this reason, childhood cataracts are an emergency medical condition where every second counts.

Causes and Risk Factors

Childhood cataracts can occur in only one eye (unilateral) or both eyes (bilateral). While the exact cause cannot always be determined (idiopathic), significant underlying factors are present in a large portion of cases:

1. Genetic and Hereditary Factors: Approximately one-third of bilateral cataracts are familial (genetic). A history of childhood cataracts in the family or consanguineous marriages significantly increases the risk.
2. Intrauterine Infections: Infections the mother experiences during pregnancy (Rubella, Toxoplasmosis, Cytomegalovirus - CMV, Herpes, Syphilis) are among the most common causes that disrupt the development of the baby's lens, leading to congenital cataracts (TORCH syndrome).
3. Metabolic Diseases: Disorders such as Galactosemia (inability to digest milk sugar), abnormalities in blood sugar, or calcium metabolism issues trigger cataract formation.
4. Syndromic Conditions: The incidence of cataracts is much higher in babies with chromosomal abnormalities such as Down Syndrome (Trisomy 21), Turner Syndrome, or Lowe Syndrome.
5. Eye Trauma: A significant portion of developmental cataracts occur later due to severe blows to the eye, sharp object injuries, or chemical burns during childhood.

Symptoms: What Should Families Look For?

Since babies cannot express that they cannot see, early diagnosis depends entirely on the careful observation of parents and pediatricians. If any of the following symptoms are noticed, a specialist ophthalmologist should be consulted without delay:

1. Leukocoria (White Pupil): The most typical and dangerous symptom. The presence of a white, gray, or pearl-colored glow in the center of the pupil, which should normally appear black. This is often noticed more clearly in dark environments or in flash photography (as a "cat's eye" reflection).
2. Strabismus (Eye Misalignment): Because the eye with the cataract cannot see clearly, the brain loses control of that eye, and a noticeable inward, outward, or upward shift begins.
3. Nystagmus (Involuntary Eye Tremor): If there are cataracts in both eyes and the baby cannot see clearly at all, the brain cannot find a point to focus on, and the eyes begin to shake rhythmically from side to side.
4. Failure to Make Eye Contact: The baby's inability (especially after 2-3 months) to focus on the parents' faces or follow light or moving toys with their eyes.
5. Light Sensitivity or Insensitivity: Some children squint excessively in bright environments, while others may show no reflex toward light at all.

Diagnosis Process and Multidisciplinary Evaluation

The diagnosis and treatment of childhood cataracts require a complex and specific approach, far different from that of adults. Our diagnostic steps include:

1. Red Reflex Test: The most fundamental screening test applied to newborns. When a pupil is viewed with a special light (ophthalmoscope), it is checked whether the healthy red-orange glow reflecting from the retina is visible. If a cataract is present, this reflection cannot be obtained; instead, a dark or white spot is seen.
2. Detailed Ophthalmological Examination (Under Anesthesia if Necessary): For uncooperative infants or young children, a full examination is performed under short-term sedation (EUA - Examination Under Anesthesia) in operating room conditions, accompanied by pediatric anesthesia teams, to measure the density of the cataract and evaluate the retina.
3. Systemic Investigation: Especially in bilateral cases, blood and urine tests are requested through medical consultations with pediatric and genetic specialists to detect any underlying genetic or metabolic diseases.

Treatment: Advanced Microsurgery and Rehabilitation

Childhood cataracts cannot be treated with medication, drops, or glasses. The only solution is the surgical removal of the opaque lens. However, this surgery is technically much more difficult than adult cataract surgery due to the high flexibility of the tissues, the fact that the eye is still growing, and the risk of severe post-operative inflammatory reactions.

Surgical Process (Pediatric PHACO and Lensectomy): The operation is performed under general anesthesia in our sterile, JCI-accredited hospitals. Using special microsurgical tools, the cataractous lens is cleared using ultrasonic energy. Because the posterior capsule of the lens becomes opaque very quickly in infants, the center of the capsule is specially opened during surgery, and a portion of the vitreous gel behind the eye is cleared (Anterior Vitrectomy). This is a vital surgical step specific to children that ensures the visual axis remains open for life.

Intraocular Lens (IOL) Decision: In children over 2 years of age, a permanent artificial lens (IOL) is usually placed inside the eye after the cataract is cleared. However, in infants under 2 years old, placing an intraocular lens is generally not preferred because the eyeball continues to grow rapidly (Aphakia). The optical rehabilitation of these babies is provided through special aphakic contact lenses or thick aphakic glasses. The artificial lens implantation is performed later when the child grows (with a secondary surgery).

The Most Difficult Stage: Amblyopia Treatment and Rehabilitation

Surgery is not the end of the treatment, but only the beginning of the brain's process of relearning how to see. Even after successful surgery, if the brain has forgotten to use that eye, laziness is inevitable. Therefore:

1. Proper optical correction (glasses or contact lenses) is applied immediately.
2. Patching Therapy: The healthy (or better-seeing) eye is covered with special patches for hours determined by the doctor, forcing the brain to use the operated and lazy eye. This is the most vital period, lasting years, requiring the family's patience and close communication with the physician.
