Cataracts in Children – Overview
Cataracts in children are a rare but serious condition where the normally clear lens of the eye becomes clouded, leading to vision impairment. While cataracts are most often associated with older adults, cataracts in children can occur from birth or develop later in childhood due to trauma, medical conditions, or genetic factors. Early detection and treatment are essential, as untreated cataracts can permanently affect a child’s vision and visual development.
The lens plays a crucial role in focusing light onto the retina, allowing us to see clearly. When this lens becomes clouded by cataracts, the light is scattered or blocked, resulting in blurred or distorted vision. In children, this disruption can affect how the brain learns to process images during critical developmental periods, particularly within the first few months and years of life.
Cataracts in children can be unilateral (affecting one eye) or bilateral (affecting both eyes), and they may vary in size and location within the lens. Some are dense and require immediate surgical intervention, while others may be small and monitored closely over time. Common symptoms include white or cloudy pupils, misaligned eyes, poor visual focus, and delayed visual milestones.
Treatment usually involves surgical removal of the cataract, typically followed by correction with glasses, contact lenses, or intraocular lenses (IOLs). Unlike in adults, children may need extensive post-operative care, including patching therapy and visual rehabilitation, to ensure the brain develops proper connections with the eyes.

Early intervention is critical. The longer a cataract remains untreated during infancy or early childhood, the higher the risk of amblyopia (lazy eye), permanent vision impairment, or even blindness. Paediatricians and parents must work closely to observe and address any visual concerns in a child’s early years.
Despite their complexity, cataracts in children are treatable. With prompt diagnosis, skilled surgical care, and diligent follow-up, many children regain excellent vision and achieve normal development. Education and awareness remain key to ensuring early signs are not missed and long-term outcomes are optimised.
