Ultrasonographic Biometry in Infantile Glaucoma. A Prospective Follow-up Study

We report a prospective follow-up study of the axial length by ultrasonographic biometry in 15 eyes with congenital glaucoma. The mean age of the patients with primary congenital glaucoma was 5.3 ± 0.8 months at the diagnosis. All had an undeniable congenital glaucoma defined by means of applanation tonometry, biomicroscopy and ophthalmoscopic studies. The postoperative followup varied from 9 to 30 months. After successful glaucoma surgery a good control of intraocular pressure was also followed by initial decrease of the axial length, while after unsuccessful operation a continued increase of the axial length was noted. We conclude that ultrasonographic biometry is an additional valuable technique to be used routinely both at the diagnosis as well as postoperative follow-up of all congenital glaucomas.
