CodeDisplayDefinition
single-optotypes Single Optotypes The visual acuity test was conducted using single optotypes.
optotype-rows Optotype Rows The visual acuity test was conducted using rows of optotypes.
optotype-presentation Optotype Presentation Whether the optotypes were presented as single optotypes or as rows of optotypes
Optotype Optotype Figures or letters of different sizes, which are discriminated by a patient in Visual acuity testing
Landolt C Landolt C Landolt C Optotype, also known as Landolt Ring Optotype
Sjogren's Hand Test Sjogren's Hand Test A Visual Acuity Test with a Chart consisting of pictures of hands with fingers pointing towards various directions.
Lea Symbol Test Lea Symbol Test A four-Optotype Visual acuity Test for Children developed by Dr Lea Hyvaerinen
Refractive Correction Refractive Correction The process of improving visual acuity by changing the paths of light rays by in order to more accurately focus it on the retina
trial-lenses-autorefraction Trial Lenses - Values from Autorefraction Trial lenses used for visual acuity testing based on values obtained from an autorefractor.
trial-lenses-manifest-without-cycloplegia Trial Lenses - Values from Manifest Refraction without Cycloplegia Trial lenses used for visual acuity testing based on values from manifest refraction without cycloplegia.
trial-lenses-manifest-with-cycloplegia Trial Lenses - Values from Manifest Refraction with Cycloplegia Trial lenses used for visual acuity testing based on values from manifest refraction with cycloplegia.
trial-lenses-retinoscopy Trial Lenses - Values from Retinoscopy Trial lenses used for visual acuity testing based on values from retinoscopy.
trial-lenses-unspecified-origin Trial Lenses - Values of Unspecified Origin Trial lenses used for visual acuity testing where the origin of the refractive values is unspecified.
VA_Confounder_Right_Pupil_Dilated The Visual Acuity measurement is confounded by a right dilated pupil after dilating eyedrop use The Pupil of the Right eye is in a Mydriatic state because dilating Eyedrops were used
VA_Confounder_Left_Pupil_Dilated The Visual Acuity measurement is confounded by a left dilated pupil after dilating eyedrop use The Visual Acuity measurement is confounded by a left dilated pupil after dilating eyedrop use
VA_Confounded_pathological_right_pupil_function The Visual Acuity measurement is confounded by a pathological right pupil function, independent of eyedrops The Visual Acuity measurement is confounded by a pathological right pupil function, independent of eyedrops
VA_Confounded_pathological_left_pupil_function The Visual Acuity measurement is confounded by a pathological left pupil function, independent of eyedrops The Visual Acuity measurement is confounded by a pathological left pupil function, independent of eyedrops
VA_not_confounded_by_pupil_function Absence of significant confounding effect of pupil function on VA measurement Absence of significant confounding effect of pupil function on VA measurement
logMAR Logarithm of the Minimum Angle of Resolution Logarithm of the Minimum Angle of Resolution as a Unit of Visual Acuity
MAR Minimum Angle of Resolution Minimum Angle of Resolution as a Unit of Visual Acuity
Decimal Decimal Unit of Visual Acuity Reciprocal value of Minimum Angle of Resolution, equivalent to calculating the fraction of a Snellen Ratio
Jaeger J Jaeger type (J) Unit Unit of Visual acuity, determined by a the smallest print read on a Jaeger chart
VAS Visual Acuity Score Unit of Visual acuity, calculated as 100 - 50 x logMAR
