Clinical presentation
presentation
Presentation of amblyopia differs on whether it is unilateral or bilateral:
- unilateral loss
- parents may not detect unless a visible condition such as strabismus is present
- may result in failure to develop stereopsis (depth perception)
- newborns may commonly present with variable ocular misalignment, but presence beyond the age of 3 months or constant misalignment requires further assessment
- bilateral loss
- patient may present with
- nystagmus
- absence of 'eye contact'
- delayed milestones of visual or motor development
- patient may present with
Further assessment is recommended without delay in patients who do not reach visual developmental milestones e.g. –
- fixes and follows light source at 6 weeks
- smiles responsively at 6-8 weeks
- fixes and follows slowly moving objects or faces at 3 months
- reaches accurately for objects in visual environment at 6 months
