Aim: To discuss a presumed case of functional bilateral amblyopia which had an eventual diagnosis of Stargardt’s disease.
Methods: Details are reported of a girl who presented to the Orthoptic Department at age 9 years having previously attended the orthoptic department as a young child. Documentation of the case is presented including the findings in childhood, the findings at later presentation and the findings when an eventual diagnosis was made.
Results: The orthoptic findings for this girl when discharged at age 8 years differed considerably from the findings at age 9. When discharged at age 8 years she showed acuities of 6/6 right and 6/12 left. A minimal residual left esotropia was present. At representation 7 months later visual acuities had dropped to 6/24 right and left. No cause for the reduction in acuity could be found.
Conclusions: Stargardt’s disease is an inherited condition which affects the macula. There is usually considerable sight loss although complete loss of vision is rare. Early in the disease the macula and the electroretinogram can appear normal, which slows the initial diagnosis. Subsequently children may be suspected of malingering. In time the characteristic changes in the retina facilitate a diagnosis.
