Ultrasonographic biometry in congenital glaucoma.

Method 'A' ultrasonographic biometry was performed on 23 patients with congenital glaucoma. The axial lengths of these eyes were significantly greater as compared to the 7 fellow eyes with normal intraocular pressures of the same patients and 10 eyes of 5 patients with megalocornea of the same age. Some of the borderline cases showed an increase of axial length during follow-up not attributable to normal growth. After successful surgery an early decrease of the axial length up to 0.8 mm could be seen. The change occurred in post-equatorial measurements. It is concluded that ultrasonographic biometry is a very valuable additional technique for the diagnosis and postoperative follow-up of congenital glaucomas.
