Cataracts, characterised by the clouding of the eye's natural lens, are a significant cause of childhood blindness, especially in low and middle income countries like India. According to the World Health Organization (WHO), cataracts contribute notably to visual impairment in children. Early detection and timely intervention are crucial in preventing lifelong vision problems. Understanding the signs and symptoms of cataracts in children can lead to prompt medical attention and better outcomes.
Common Signs and Symptoms
Cloudy or Blurry Vision- The most evident symptom of cataracts is cloudy or blurry vision. As the lens of the eye becomes opaque, it obstructs the passage of light, leading to diminished clarity. Children may struggle to see details and often describe their vision as looking through a foggy window. This can affect their ability to perform everyday tasks and engage in activities that require clear vision.
Light Sensitivity- Children with cataracts often exhibit heightened sensitivity to light, also known as photophobia. Bright lights can be uncomfortable and sometimes painful, causing children to squint or turn away from light sources. This sensitivity can hinder their ability to play outdoors or participate in brightly lit environments.
Difficulty Seeing in Low Light- Cataracts can make it challenging for children to see in dim lighting conditions. Activities like reading at bedtime or playing in shaded areas become difficult, as the reduced light exacerbates the already limited vision. This symptom is particularly noticeable in settings with varying light conditions, where the contrast is essential for clear sight.
Visible Cloudiness in the Eye- One of the more apparent signs of cataracts in children is a noticeable cloudiness or whitish-grey spot in the pupil. This physical change is often detected by parents or caregivers and warrants immediate medical attention. The cloudiness indicates the progression of the cataract, which can severely impair vision if left untreated.
Abnormal Eye Movements- Children with cataracts may develop nystagmus, characterized by involuntary eye movements, or strabismus, commonly known as crossed eyes. These abnormal movements can indicate visual impairment and often signal the need for further examination. Strabismus, in particular can affect depth perception and coordination.
Delayed Development- Infants with cataracts may have delayed development of their vision. A child may not track moving objects, recognize familiar faces, or engage with their surroundings as expected. These developmental delays highlight the importance of early eye examinations to identify and address visual impairments promptly.
Poor Eye Contact- Babies and young children with cataracts may avoid making eye contact due to their compromised vision. This lack of engagement can be mistaken for other developmental issues, but it often stems from an inability to see clearly. Noticing these behavioural changes early can lead to timely intervention.
Squinting or Head Tilting- Children might squint or tilt their heads to see better or reduce glare. These behaviours are coping mechanisms to maximize the remaining vision and can be signs of underlying cataracts.
Cataracts in children can be congenital (present at birth) or acquired after birth due to various factors such as trauma, infections, or diseases. Congenital cataracts are often related to genetic conditions or infections during pregnancy, while acquired cataracts might result from eye injuries or illnesses.
Ayurvedic Approach to Checking Paediatric Cataracts
Ayurveda offers complementary methods for detecting and managing paediatric cataracts.
Pulse Diagnosis (Nadi Pariksha) Practitioners assess the pulse to detect imbalances in the body's energies (doshas) that could contribute to eye conditions.
Examination of Eyes (Netra Parikshan) Detailed examination of the eyes using Ayurvedic techniques helps in identifying early signs of cataracts.
Herbal and Dietary History Reviewing the child's dietary habits and exposure to herbal treatments provides insights into potential nutritional deficiencies or imbalances.
Use of Traditional Ayurvedic Texts Referring to ancient Ayurvedic texts can guide the diagnosis and suggest preventive measures or treatments using natural remedies.
Dietary Suggestions for Supporting Eye Health in Children with Cataracts
Ensure the child's diet is rich in Vitamin A, which is crucial for good vision and overall eye health, by incorporating foods such as carrots, sweet potatoes, spinach, kale, butternut squash, and liver.
Vitamin C acts as an antioxidant and helps prevent oxidative damage to the eye. Include citrus fruits like oranges, lemons, and grapefruit, as well as strawberries, bell peppers, broccoli, and kiwi in their diet.
To protect eye cells from free radical damage, include sources of Vitamin E such as nuts (almonds, hazelnuts), seeds (sunflower seeds), spinach, and avocados.
Support overall eye health and reduce inflammation with Omega-3 fatty acids found in flaxseeds, chia seeds, walnuts, and fish-like salmon and sardines.
Lutein and zeaxanthin are carotenoids concentrated in the retina that help protect against light-induced damage. Incorporate green leafy vegetables like kale, spinach, and collard greens, as well as corn and eggs, into their meals.
Zinc is vital for maintaining the health of the retina and may help delay the progression of cataracts. Include zinc-rich foods such as pumpkin seeds, chickpeas, lentils, and whole grains in their diet.
Early recognition of cataracts in children is critical for preventing vision loss. Modern medical treatments combined with Ayurvedic practices can enhance the overall management and prognosis of pediatric cataracts. Parents and caregivers should remain vigilant for the signs and symptoms outlined above and seek prompt medical advice if they suspect any visual impairments in their children.
