Axial Length, Anterior Chamber Depth, Lens Thickness and Horizontal Corneal Diameter in Normal Children

Abstract

 

Abstract:

 

To determine the mean values of axial length (AXL),anterior chamber depth (ACD), lens thickness (LT) and horizontalcorneal diameter (HCD) on normal children (ages from 1 day to79 months).

 

133 normal children (77 males and 56 females) wereexamined under narcosis with Penthrane (until 1985) and Methoxifluorane(after 1985). We examined 66 normal children (both eyes) and67 normal eyes of children with unilateral ocular diseases (mostlyprimary or secondary congenital glaucoma). Some children wereexamined on different dates repeatedly in order to evaluatethe evolution of unilateral glaucoma. The echobiometric parameterswere measured by the same doctor using the 8 MHz probe fromKretz model 7200 MA (until 1995) and the A–Scan /PachymeterDGH 5100e (after 1995) and, the horizontal corneal diameterwas measured using the Jameson's calyper. For statistical analysiswe have considered only one normal of non–glaucomatouschildren. The tables 1 and 2 summarize our data.

 

 

 

The echobiometric parameters (AXL, ACD and LT)and the HCD of the normal eyes showed a tendency to a progressiveincrease until 36 months. We suppose that after 36 months thattendency could be found if we had examined a greater numberof eyes.
