Retrospective safety assessment of apraclonidine for diagnosis of Horner’s syndrome in children

Anisometropia following cataract surgery and its non-surgical treatment

The desired result of cataract surgery is improved visual acuity without the use of spectacles. In practice most patients following initial cataract extraction are likely to be symptomatic of anisometropia giving rise to prismatic effects (anisophoria) and unequal retinal image...
