Objectives: To investigate whether the testing of two groups of children with pseudoisochromatic tables by Ishihara will give the difference in the form of difficult interpretation, ie slower reading speed of tables for children with special needs, but in healthy children. Study design: Cross-sectional study. Place of research: Primary school “Spinut” and Center for education “Slava Raškaj” in Split. Main outcome measures: Main outcome measure is time needed for reading pseudoisochromatic tables by Ishihara in both tested groups. Results: Among all plates of Ishihara tables, plates 7 and 13 were most often wrong interpreted. There wasn't statistically significant difference proved on plate number 7 between healthy children and children with special needs (χ² = 0.084; P = 0.771). Also, there wasn't statistically significant difference proved on plate number 13 between healthy children and children with special needs (χ² = 0; P = 1). Difference of medians of time needed for reading Ishihara tables between healthy children and children with special needs was 5 seconds most and 1 second least. All differences of medians of time needed for reading Ishihara tables were statistically significant (P<0.001). Conclusion: There was no statistically significant differences in amount of mistakes between tested groups. Children with special needs need statistically significant more time to read all plates of Ishihara tables so they need more patience and we must be led by individual aproach. Our conclusion is that pseudoisochromatic tables by Ishihara are good method for testing colour vision in children with special needs.
