A comparative study of testicular biometry was done in rams using three major breeds of sheep in Nigeria. Biometrical parameters observed were scrotal circumference (SC), testes weight (TW), testes length (TL), tunica albuginea weight (TAW), testes volume (TV), testes density (TD), epididymal weight (EW), epididymal length (EL), caput (CA), corpus (CO), cauda weight (CU), epididymal volume (EV)...

PURPOSE To evaluate the accuracy of intraocular lens power estimation in eyes having phacovitrectomy for rhegmatogenous retinal detachment. METHODS Retrospective case review of 100 consecutive eyes that underwent phacovitrectomy for rhegmatogenous retinal detachment. Axial lengths were measured using optical biometry and/or ultrasound A-scan. Achieved and predicted refraction were compared to...

Background. The aim of our work was to determine changes in opticalanatomical elements of myopic eyes of full-term and premature children during accommodation by means of precise ultrasonic biometry. Materials and methods. The study was made on healthy full-term children’s eyes with emmetropic refraction (group, n = 20); full-term 1st degree myopic children’s eyes with refraction from -1.0 D to...

background: although many countries had improvement in heath system in last twenty years but expense of research and its difficulties does not allow managers to solve their problems by doing research. if we accept that biostatistics is one of the scientific tools for research, we imply that in all domains of health system research applying statistical techniques is essential. this study was per...

Biometric study in a series of 11 affected males provides characteristic findings. The patients present with a large cornea with short radius, very deep anterior chamber depth (AC depth) exceeding the normal mean value of plus 2 SD, and a short vitreous length. Calculation of the postlimbal depth, a method applied in this study to obtain information about positioning of the iris and the lens, r...

BACKGROUND AND PURPOSE The availability of data relating to the biometry of the CC in children that are easy to use in daily practice is limited. We present a reference biometry of the CC in MR imaging in a large cohort of children. MATERIALS AND METHODS Cerebral MR imaging studies of children with normal examination findings were selected retrospectively. Children born preterm and those with...
