Failure to identify and treat eye symptoms can lead to compromise of sight, or even sight loss. Common problems can include cataracts, glaucoma (high pressure in the eyeball), squint, or similar.
Cataracts or other obstruction of light to the eye can be particularly damaging in the early years. The visual system develops gradually with the brain “learning” to interpret the information given to it by the eyes. If that flow of information is hampered for long enough, the eye can effectively “shut down” even though it is perfectly healthy in itself. Once this has happened, nothing can restore its function.
Regular eye checks are particularly important for young children and any abnormalities should be carefully investigated and followed up with appropriate treatment.
