hereditary retinopathies – inflammatory eye diseases – metabolic disorders – vitamin A deficiency – impaired night vision

Dear Doctor, is my night vision normal?

This question often put to ophthalmologists is not an easy one to answer, as “night vision problems” may originate both from dazzling or contrast vision defects of optical or neuronal origin. To detect “night vision problems”, all these factors have to be checked to ensure that the patient will be able to recognize e.g. a person who is dressed in dark clothes and crosses the street. But in order to really respond to this patients’ question, it is necessary to determine the absolute sensitivity for light. This function is measured by a dark adaptation curve over a period of about 30 minutes. There is no other examination which allows to diagnose absolute light sensitivity.
