A computerized dark adaptometer (AdapDx, MacuLogix, Inc., Middletown, PA, USA) was used in three patients to verify that full dark adaptation had been obtained at the end of the examination [22].
For many years the 'gold-standard' instrument for measuring dark adaptation and absolute scotopic sensitivity was the Goldmann-Weekers adaptometer (Haag-Streit, Switzerland).
This has led to the recent development of a commercially available, clinically friendly, short-duration dark adaptometer instrument (the AdaptDx, MacuLogix, USA).
