Abstract:

Results of combined ultrasound scanning for estimation of acoustic lens density and biometric relations of lens and other eye structures are presented. A group of 124 patients (189 eyes) was studied; they were subdivided depending on age and length of anteroposterior axis of the eye. Examination algorithm was developed that allows selective estimation of acoustic density of different lens zones and biometric measurements including volumetric. Age-related increase of acoustic density of different lens zones was revealed that indirectly shows method efficiency. Biometric studies showed almost concurring volumetric lens measurements in "normal" and "short" eyes in spite of significantly thicker central zone of the latter. Significantly lower correlation between anterior chamber volume and width of its angle was revealed in "short" eyes and "normal" and "long" eyes (correlation coefficients 0.37, 0.68 and 0.63 respectively).
