Saccadic Alterations in Severe Developmental Dyslexia

Table 1

𝐴/𝐷 relation and 𝐴/𝑉_𝑝 relation regression parameters in the first and second saccadic tests. RE: right eye; LE: left eye.

(a)

𝐴/𝐷 relation	First exam		Second exam
	m	q	m	q
RE to the right	2.25	32	2.21	36
RE to the left	−1.89	42	−2.27	38
LE to the right	2.85	49	2.98	49
LE to the left	−1.83	40	−2.16	36

(b)

𝐴/𝑉𝑝 relation	First exam		Second exam
	1/𝛼	1/𝛽	1/𝛼	1/𝛽
RE to the right	730	68	822	55
RE to the left	−798	−49	−752	−54
LE to the right	662	53	685	44
LE to the left	−1100	−48	−894	−54

The normal values for ages 14–18 years in our laboratory for A/D relation are m = 1.87 ± 0.58 and q = 33 ± 6 and for A/𝑉_𝑝 relation are 1/α = 1094 ± 308 and 1/β = 59 ± 18. In both exams only the 4 parameters of the LE to the right are out of the range of normality.
