Down Syndrome

Down Syndrome

Characteristic appearance of the eyes: Wide-set eyes (hypertelorism) with significant Epicanthal Folds which may give the appearance of eyes being “turned in”.



Iris Changes: Peripheral thinning and "Brushfield Spots"


Cataracts: appear during the first decade and may be progressive, however, usually they do not significantly impair vision.


Nearsighted: can see close but not far away

Farsighted: must work to see at distance but harder at near.

Astigmatism: distorted vision at all distances.  


Strabismus: turned or wandering eye–usually turned IN.


Keratoconus: thinning cone-shaped corneal degeneration which causes distorted vision.

Higher Incidence of:

Nystagmus: repetitive, rapid, involuntary eye movements.

Blepharitis: infection of the eyelids.

Ectropion: eyelid margin turned out.

Anisometropia: difference in correction between the two eyes (makes it difficult to use them together as a team).

Amblyopia: where normal eye does not develop normal vision mostly due to lack of use (unequal correction, strabismus, etc.)

Oculomotor Dysfunction: difficulty controlling and coordinating eye movements.

Accommodative Anomalies: difficulty focusing.
