Oh!Pama: is my baby's "cross-eyed" look really strabismus?

Key points: A baby who looks cross-eyed may have one of two very different things. Pseudoesotropia is an optical illusion — an infant's flat, broad nasal bridge and the epicanthal folds beside it cover part of the white of the eye, so the pupils look as though they sit too close to the nose, while ocular alignment is in fact normal. It resolves as the face develops. True infantile esotropia is a genuine misalignment that needs early detection and management: the brain suppresses the image from the deviating eye, and binocular vision and stereopsis do not develop normally.

In the interview Crystal demonstrates a preliminary check parents can do at home: in good lighting, take a front-facing photo of the child and compare the corneal light reflex in each eye. If both reflections sit symmetrically near the centre of each pupil, pseudoesotropia is more likely; if one is clearly displaced, the child should be examined by an optometrist or ophthalmologist. This is a preliminary observation only and does not replace a clinical assessment.

For formal assessment and management options, see how childhood strabismus is treated and whether vision therapy is still needed after strabismus surgery, or book a comprehensive paediatric eye examination.

Street interview: enlarging your phone fonts? An optometrist explains presbyopia

Street interview by the "健康專家 Health Expert" YouTube channel | Interviewee: Crystal Wong 王水晶 (Registered Optometrist, Hong Kong) | In Cantonese

Many people assume that enlarging their phone fonts, or holding the phone further and further away, is just a normal part of getting older. In this street interview, Crystal explains what causes presbyopia — and why simply "working around" it can mask cataract, macular or other eye degeneration. That is why, beyond reading glasses, adults over 40 should also have regular comprehensive eye examinations.

If you or your family are finding near work increasingly tiring, you are welcome to book a comprehensive eye examination, or watch the original video on YouTube (in Cantonese).
