PURPOSE To evaluate choroidal blood flow changes in eyes with high myopia according to the pulsatile components of ocular blood flow analysis. METHODS A total of 104 subjects (52 males and 52 females) were included in this study. One eye of each participant was randomly selected and assigned to one of four refractive groups, designated as, hyperopes (n = 20; refractive error, ≥+1.00 diopter [...

BACKGROUND To determine the relationship between central corneal thickness (CCT), refractive error, corneal curvature, anterior chamber depth and axial length in normal Taiwanese Chinese adults. METHODS Five hundred normal Taiwanese Chinese patients aged 40-80 years were recruited for the study. Measurement procedures included CCT, refractive error, corneal curvature, anterior chamber depth a...

BACKGROUND The factors that influence pulsatile ocular blood flow (POBF) were evaluated in normal subjects. METHODS POBF was measured in 80 normal subjects using Langham OBF computerised tonometry. The effect of age, systolic and diastolic blood pressure, refractive error, intraocular pressure, and axial length on POBF was evaluated using multiple regression analysis. RESULTS The mean (SD) ...

BACKGROUND Effective therapeutic options are limited for the management of chronic central serous chorioretinopathy (CSCR) complicated by exudative retinal detachments (RD). The authors describe the resolution of one such case following partial thickness scleral resection with mitomycin C. CASE PRESENTATION This 39-year-old male presented with a unilateral inferior exudative RD in the right e...

BACKGROUND: Though the development and fitting of scleral contact lenses are expanding steadily, there is no simple method to provide scleral metrics for scleral contact lens fitting yet. The aim of this study was to establish formulae for estimation of the axial radius of curvature (ARC) of the anterior sclera using ocular biometric parameters that can be easily obtained with conventional de...

PURPOSE To investigate the association between subfoveal choroidal thickness and ocular axial length, refractive error, and blood pressure in healthy young women and men. METHODS Cross-sectional observational study of 93 eyes in 93 healthy Danish university students (mean age 24.9 ± 2.6 years). The submacular choroid was imaged using enhanced-depth imaging spectral domain optical coherence to...

PURPOSE To determine the effect of anthropometric parameters on refraction and ocular biometry. METHODS Noncontact methods were used to examine ocular dimensions and cycloplegic refraction in a stratified random cluster sample of year-1 Sydney school students (mean age, 6 years; n = 1765). Height, body weight, and waist circumference were measured according to a standardized protocol. Body ma...

PURPOSE To determine the axial length requiring adjustment of measured circumpapillary retinal nerve fiber layer (cpRNFL) thickness to account for ocular magnification during spectral-domain optical coherence tomography (SD-OCT). METHODS In this prospective study, 148 eyes of 148 healthy student volunteers were imaged by two examiners using three-dimensional SD-OCT. In 54 randomly selected ey...
