[Planimetric characteristics of the optic papilla in relation to age]

Percentage relation of the neuroretinal rim area to the total optic disc area was examined planimetrically in relation to the age of 116 probands having no optic disease and divided into the age decades from 3 to 7. In 3rd decade percentage of the neuroretinal rim area was on average 90.26% (min. 81.2; max. 93.6 standard deviation 3,225). In 4th decade average area was 89.92% (min. 83.7; max. 96.5 standard deviation 3,494). In 5th decade average area of the neuroretinal rim area was 88.583% (min. 78.6; max. 95.5 standard deviation 4,496). In 7th decade average are was 82.448% (min. 73.8; max. 93.5 standard deviation 4,758). Significance of the value differences found by means of t-Student non-pair test: significant differences were found between the parametres in 3rd and 6th decades (p is less than 0.01); between 3rd and 7th decades (p is less than 0.001); between 4th and 6th decades (p is less than 0.01); between 4th and 7th decades (p is less than 0.001); between 5th and 7th age decades (p is less than 0.001) and between 6th and 7th age decades (p is less than 0.01). No significant differences were found between the parametres of the age decades 3 and 5, 3 and 4, 4 and 5, 6 and 7.
