The role of Eye biomechanical parameters in the development of congenital glaucoma in children

The objective of this review was to study biomechanical parameters of the eye in children with different stages of congenital glaucoma. 20 patients (40 eyes) aged from 1 month to 3 years with simple primary congenital not operated glaucoma were examined. 7 patients (14 eyes) entered in the 1st group (developed stage), 8 patients (16 eyes) - the 2nd group (passed stage), 5 patients (10 eyes) - the 3rd group (end-stage) respectively. Research methods included visiometry, refractometry, ophthalmoscopy, definition of the optic disc excavation, ultrasound A-scan of the anterior posterior size of the eye, Filatov’s - Kalfa elastotonometry with weights 5g, 10g, 15g. The analysis of the data shows that gradient of the elastotonometry graphs elevation registered in all groups, but the highest was in group of children with terminal stage. Thus the anteroposterior size of the eye and intraocular pressure increase corresponding to disease severity. Biomechanical parameters of the eye increase according to the stages of a congenital glaucoma first form. The decrease of sclera rigidity shows morphological changes of the eye tissue and severity of glaucoma process.
