Eyelid infections in children include styes, chalazia, blepharitis and cellulitis. Most are mild and settle with warm compresses and drops. When fever, forward displacement of the eye or restricted eye movements appear, the infection may have reached the orbit and needs urgent care.
Astigmatism is a refractive error caused by irregular curvature of the cornea or lens, so light cannot focus at a single point on the retina. In children it causes blurred vision, squinting, headaches and reading difficulty, and untreated it can lead to amblyopia. Early examination protects visual development.
Hyperopia is a refractive error in which light focuses behind the retina. Children can read the chart normally yet struggle with near work, develop headaches or show an inward turning eye. Cycloplegic refraction reveals the true degree, and the right glasses prevent esotropia and amblyopia.
Myopia makes distant objects blurry because light focuses in front of the retina. It usually starts at school age and can increase during growth. Trouble seeing the board, squinting and sitting close to the television are the first signs. Correct glasses and regular follow-up protect vision and track progression.
Strabismus means the eyes cannot fix on the same point. Because a child's brain suppresses the deviating eye, untreated squint leads to amblyopia. Glasses, patching and, when needed, muscle surgery can restore both alignment and vision, and the age at which treatment starts shapes the result.
Childhood glaucoma is raised intraocular pressure that damages the optic nerve. Because an infant's eye is elastic, it enlarges under pressure, so large eyes, light sensitivity and constant watering are the key warning signs. Surgery is the main treatment and follow-up continues for life.
Congenital cataract is clouding of the lens present at birth or appearing in the first months. A white pupil, failure to follow objects and nystagmus are the main signs. Because it occurs while the visual system is developing, the timing of surgery directly determines the outcome.
Structural eyelid disorders in children include ptosis, entropion, ectropion, epiblepharon, coloboma and eyelid masses. When the lid cannot protect the cornea or blocks the visual axis, irritation, corneal damage and amblyopia can follow, and treatment is planned around those risks.
Ptosis in children means the upper eyelid sits lower than normal. When the lid covers the pupil, or presses on the cornea and induces astigmatism, amblyopia follows. The decision to treat is therefore based on visual development rather than on appearance.
Eyelid haemangiomas are common benign vascular lesions of infancy. They grow rapidly in the first months and then shrink over years. Lesions that pull the eyelid down or press on the cornea can cause amblyopia and are treated rather than watched.
Most masses and cysts found around a child's eyelid at birth or in the first months are benign. Dermoid cysts, haemangiomas, epibulbar dermoids and lacrimal cysts are the commonest. What guides management is the effect on the eyelid and on vision, not the appearance.
When a congenital tear duct blockage has not opened by the first birthday, intervention comes onto the agenda. Probing, silicone intubation, balloon dacryoplasty and, rarely, duct surgery are used from that point. This page covers timing, how each procedure is carried out, what is done when the blockage recurs, and long-term follow-up.
Sight is not a ready-made ability. A baby's eye is anatomically complete at birth, but the brain has not yet learned to see. The sharp image falling on the retina shapes the visual pathways through the first years. If one eye cannot receive a clear image during that period, its development falls behind and amblyopia (lazy eye) sets in.
The hardest part of amblyopia is how quietly it progresses. The child copes with the better eye, reads, plays, and never complains. Parents notice nothing, because there is nothing to notice. The problem usually surfaces only at a screening examination. Since the visual pathways are most adaptable in the preschool years, what matters most in paediatric ophthalmology is not a symptom the family reports but an examination performed on time.
This is the schedule I recommend for a healthy child without complaints. Intervals are shortened where there is a family history of eye disease, premature birth or developmental delay.
In the short video below I explain what a swelling at the inner corner means in a baby, and when it should not wait.
After cycloplegic drops the pupils stay large for a few hours, near vision is blurred and bright light is uncomfortable. It helps to avoid scheduling the visit on a demanding school day and to bring sunglasses or a hat.
Most childhood eye conditions can be treated successfully when they are caught in time. What is usually lost is not the condition itself but the time. Bringing your child for examination at the recommended ages, even without any complaint, is the most practical way to protect visual development.
