PURPOSE To examine the extent to which the two major determinants of refractive error, corneal curvature and axial length, are scaled relative to one another by shared genetic variants, along with their relationship to the genetic scaling of height. METHODS Corneal curvature, axial length, and height were measured in unrelated 14- to 17-year-old white European participants of the Avon Longitu...

PURPOSE This prospective study was conducted to assess the influence of overnight orthokeratology (OK) on axial elongation in children, with those wearing spectacles as controls. METHODS One hundred five subjects (210 eyes) were enrolled in the study. The OK group comprised 45 patients (90 eyes, age 12.1 ± 2.5 years, mean ± SD; OK group) who matched the inclusion criteria for OK. The control ...

Objective. To report interocular differences in choroidal thickness in children using spectral domain optical coherence tomography (SD-OCT) and correlate findings with biometric data. Methods. This observational cross-sectional study included 91 (182 eyes) healthy children aged 6 to 17 years with no ocular abnormality except refractive error. After a comprehensive eye exam and axial length meas...

OBJECTIVE To determine the potential risk factors for retinal detachment after cataract surgery. METHODS In this retrospective cohort study, medical records of patients operated on between 2000 and 2010 at the Department of Ophthalmology, King Abdulaziz University Hospital, Riyadh, Kingdom of Saudi Arabia were retrospectively reviewed for both demographic and clinical data. Cases were identif...

Thirty-seven consecutive patients (41 eyes) diagnosed with primary angle closure glaucoma (PACG) attending the Glaucoma Clinic in University Malaya Medical Centre, over a period of 6 months were categorized into acute, subacute and chronic PACG from their clinical presentation. Each case was subjected to automated refraction, A-scan biometry for anterior chamber depth, axial length and lens thi...

Background: Purpose/Aim: To assess ocular parameters in Nepalese children with severe anisometropic amblyopia. Methods: This was a hospital-based cross-sectional analytical study conducted in a tertiary eye center in Nepal. Twentyone children aged 7-12 years with severe anisometropic amblyopia (>3D of anisometropia) were included in the study. Relevant demographic and clinical data were obtaine...

AIMS To characterise changes in ocular dimensions after combined cataract operation and trabeculectomy with mitomycin C using separate incisions (combined operation). METHODS 24 consecutive eyes that had combined operation and 16 eyes that had cataract operation alone were enrolled. The axial lengths before and after operations were determined with non-contact optical coherence biometry. The ...

(1) Background: Amblyopia is an ocular condition leading to structural and functional changes. The relationship between these changes complex remains poorly understood. (2) Methods: Participants included 31 children aged 5 9 years with strabismic (n = 9), anisometropic 16) mixed 6) unilateral amblyopia, 14 age-matched non-amblyopic children. 95% 63% Bivariate Contour Ellipse Area (BCEA), axial ...

Introduction: Myopia or short sightedness, is that form of refractive error wherein parallel rays of light come to a focus in front of the sentient layer of the retina when the eye is at rest; the eye is thus relatively too large, and the condition is the opposite to that of hypermetropia. Aims and objectives of the research were to find out whether there is a correlation between axial length, ...
