PURPOSE To study the distribution of spherical equivalent refraction and ocular biometric parameters in a young Australian population. METHODS Noncontact methods were used to examine ocular dimensions and cycloplegic autorefraction in a stratified random cluster sample of year 1 Sydney school students (n = 1765), mean age 6.7 years (range, 5.5-8.4 years). Repeated measures of axial length, an...

PURPOSE To investigate the association between ocular dominance (sighting dominance) and refractive asymmetry in phakic patients. METHODS This retrospective study included 3,012 patients with a mean age of 29.0 ± 5.3 years (range: 20 to 39 years). Refractive error was determined with cycloplegic refraction and axial length was determined with IOLMaster (Carl Zeiss Meditec, Dublin, CA). Ocular...

Purpose To investigate the ocular parameters of premature infants without ROP at gestational age (GA) more than 28 weeks and their relationship with growth parameters. Methods 76 preterm infants without ROP and 65 term infants were involved to undergo portable slit lamp, RetCam3, ultrasonic A-scan biometry, and cycloplegic streak examination at their 40 weeks' postconceptional ages (PCA). Ocu...

Coordination among anatomical components (Ocular biometrics) of the eye [corneal and lens power (CP/LP), anterior chamber depth (ACD), thickness (LT), axial length (AL)] determine refractive state eye. Ocular biometric measurements are crucial for selection correct IOL prescription to achieve desired outcome after cataract surgery errors respectively. This was a cross-sectional study conducted ...

PURPOSE To distinguish the frequently misdiagnosed plateau iris eyes from pupillary block group and normal group, we compared the ocular biometrical parameters of them by A-scan ultrasongraphy. METHODS In total, we retrospectively reviewed general characteristics and ocular findings including ocular biometric measurements of 71 normal, 39 plateau iris, and 83 pupillary block eyes. RESULTS T...

Ultrasound measurement of ocular dimension is the chosen method for assessing axial length when determining dioptric power for intraocular lens. From the current results of 30 cases studied, the mean axial length ranges from 22 to 23 mm. Despite the limitation of the accuracy of the ultrasonic measurements with the 7.5 mHz transducer, the power of intraocular lens can. be determined satisfactor...

Biometry performed in patients with unilateral dense congenital cataracts and unilateral complete blepharoptosis did not show a consistent elongation of the involved eye. The antero-posterior axis of the visually deprived eye was longer than that in the normal fellow eye in some but shorter or unchanged in other patients. These findings are in accord with the hypothesis gained from monkey exper...

PURPOSE To evaluate the normal distribution of exophthalmometric values in Turkish adult population and the effect of age, gender, refractive status and axial length on globe position. METHODS One hundred and twenty-two males and 114 healthy females with age ranging from 18 to 87 years were included in the study. The study population was recruited from patients presenting to our institution f...

PURPOSE To assess a potential role of Bruch´s membrane (BM) in the biomechanics of the eye, we measured its thickness and the density of retinal pigment epithelium (RPE) cells in various ocular regions in eyes of varying axial length. METHODS Human globes, enucleated because of an ocular tumor or end-stage glaucoma were prepared for histological examination. Using light microscopy, the histol...

purpose: to evaluate ocular biometric changes after phacotrabeculectomy and its effect on intraocular lens power calculation. methods: twenty six eligible eyes (24 patients) underwent phacotrabeculectomy. they were reexamined at least 6 months after the operation in a historical cohort study. main outcome measures included axial length (al) with contact a- scan (us-8000, nidek, gamaguri, japan)...
