Abstract [sv]

Syfte: Syftet med studien var att undersöka huruvida det går att urskilja färger i det perifera synfältet samt om färgperceptionen skiljer sig åt mellan olika excentriciteter.

Metod: I studien deltog 10 personer. Medelåldern var 23 år (omfång 19 till 29 år). Färgperceptionen hos deltagarna testades genom att LED-dioder i fyra olika färger presenterades vid olika excentriciteter i periferin. Excentriciteter som testades var 0-60° temporalt med 10° mellanrum. Testet utfördes på höger öga för samtliga deltagare.

Resultat: Samtliga deltagare kunde urskilja de olika färgerna ut till 40°. Vid 50° sjönk antal korrekta svar betydligt och vid 60° kunde deltagarna inte längre urskilja färgerna. Resultaten visade ett mycket signifikant samband (p<0,0001)  mellan färgperception och excentricitet. En mycket signifikant skillnad (p<0,0001) hittades mellan färgperceptionen i fovea och vid 50° repektive 60° excentricitet. Däremot hittades ingen signifikant skillnad (p>0,05) mellan fovea och 10-40°.

Slutsats: Det är möjligt att urskilja färger i periferin ut till åtminstone 40°. En viss skillnad i färgperception mellan olika excentriciteter finns; detta kan dock bero på fler faktorer utöver excentricitet.

Abstract [en]

The aim of this study was to see whether it is possible to detect and distinguish different colours in the peripheral field of vision and also if the colour perception differs between different eccentricities.

10 people participated in the study; the study was conducted on the right eye for each participant. The average age was 23 years with a range from 19 to 29 years. The colour perception was tested by presenting four different coloured LED-diodes (red, green, blue and white) at different eccentricities in the periphery. The eccentricities tested were 0-60° temporally in 10° intervals.

All participants were able to distinguish the four colours out to 40°. At 50° the number of correct answers dropped significantly and at 60° the participants could no longer distinguish the colours. A highly significant correlation (p<0,0001) was found between colour perception and eccentricity. A highly significant difference (p<0,0001) was found between colour perception in the fovea and at 50° and 60°. However there was no significant difference (p>0,05) between the fovea and 10-40°.

It is possible to distinguish colours in the periphery out to at least 40°. There is also a certain difference between the colour perception at different eccentricities. This difference could however depend on other factors besides eccentricity.
