Demographic characteristics of the young Marfan syndrome patients with ectopia lentis among different age subgroups.

Age groups (years)	Y1 (3–5)	Y2 (6–10)	Y3 (11–15)	Y4 (16–20)	value
Eyes (N)	26	65	30	14
Male/female	6/7	15/19	8/7	4/3	0.890
Right/left	13/13	32/33	15/15	7/7	1.000
AL (mm)	23.55 ± 2.11	25.28 ± 2.43	26.31 ± 2.67	26.36 ± 2.66	<0.001
Km (D)	40.59 ± 1.43	40.78 ± 1.99	40.56 ± 1.49	41.63 ± 1.78	0.269
AST (D)	1.55 ± 0.93	1.73 ± 1.03	1.78 ± 0.88	1.68 ± 0.96	0.838

AL: axial length; Km: mean keratometry; D: diopters; AST: corneal astigmatism; P values represent general differences among subgroups.
