PURPOSE To investigate the refractive status and optical components of premature babies with or without retinopathy of prematurity (ROP) at 3-4 years old, and to explore the influence of prematurity and ROP on the refractive status and optical components. METHODS Premature babies receiving fundus examination were recruited into ROP group and non-ROP group, with age-matched full-term babies as...

Axial length (AL) is a significant indicator of eyeball development, but reports on the overall status of axial development in congenital cataract (CC) patients and its relationship with patient demographics, such as age, sex, and laterality, are rare. We prospectively investigated the AL of 1,586 patients ≤ 18 years old and undergoing cataract surgery in China from January 2005 to December 201...

BACKGROUND/AIM To investigate the biometric components and refractive errors in premature infants with or without retinopathy of prematurity (ROP). MATERIALS AND METHODS Anterior chamber depth, lens thickness, vitreous length, and axial length were measured with an ultrasound biometer. Cycloplegic refraction was performed by streak skiascopy. Infants with or without ROP were grouped according...

PURPOSE To investigate optic nerve head size and retinal nerve fiber layer (RNFL) thickness according to refractive status and axial length. METHODS In a cross-sectional study, 252 eyes of 252 healthy volunteers underwent ocular biometry measurement as well as optic nerve head and RNFL imaging by spectral-domain optical coherence tomography. Correlation and linear regression analyses were per...

A model of the axial change in ocular parameters of the guinea pig eye from 2 to 825 days of age was developed and a corresponding paraxial schematic eye model applicable from 2 to 100 days of age was constructed. Axial distances increased logarithmically over time except for the lens in which growth was more complex. Over the first 30 days, ocular elongation was approximately linear: ocular le...

BACKGROUND Ocular biometric parameters can be influenced by race, ethnicity, and genetics; their differences across different populations can probably explain differences in refractive errors in these populations. The aim of this study is to determine the normal range of axial length, anterior chamber depth, lens thickness, and vitreous chamber depth in the population of Shahroud in the north o...

Objectives This study aimed to compare the presence of blepharitis, ocular tension (OT) with corneal thickness, refractive values and axial length changes in premenopausal postmenopausal women. Materials methods Thyroid-stimulating hormone (TSH), follicle-stimulating (FSH), luteinizing (LH), oestradiol (E2), prolactin, refractions horizontal vertical meridians, OT values, length, central thickn...

Objective-The aim of this research was to compare transcorneal and transpalpebral ultrasonography study of the dimensions (ecobiometry) and the ultrasonographic aspect of Iranian mix breed dogs.Design- Experimental studyAnimals- . Ten adult male dogsProcedure- Ten adult male dogs with the mean age 4±1.39 years...

To investigate the association between macular thickness and peripapillary retinal nerve fiber layer (RNFL) thickness in Chinese children. This cross-sectional study recruited consecutive cases of healthy pediatric subjects aged 4 to 18 from Caritas Medical Centre in Hong Kong Special Administrative Region, China, from 2013 to 2014. Subjects with only eye, ocular tumors, congenital glaucoma, co...
