PURPOSE To evaluate choroidal thickness (CT) in healthy and glaucomatous eyes using Swept Source Optical Coherence Tomography (SS-OCT). METHODS A cross-sectional observational study of 216 eyes of 140 subjects with glaucoma and 106 eyes of 67 healthy subjects enrolled in the Diagnostic Innovations in Glaucoma Study. CT was assessed from wide-field (12×9 mm) SS-OCT scans. The association betwe...

Axial length of the eye correlates with magnitude myopia. However, there are conflicting reports on relationship between certain corneal parameters myopia magnitude. The objective this study was to compare ocular biometry and emmetropic myopic groups. Participants (n=127) were categorized as emmetropia (spherical equivalent, SE, ±0.50D), low (-0.75D≤SE<-6.00D) high (SE≥-6.00D). difference in...

PURPOSE To clarify retinal control on scleral growth in form-deprivation myopia (FDM) in the chick, the authors studied change in transforming growth factor-beta (TGF-beta) in the form-deprived eye and the effect of this growth factor on scleral cell proliferation and axial length. METHODS Change in TGF-beta in FDM in the chick was measured by reverse transcriptase polymerase chain reaction (...

BACKGROUND To evaluate ocular biometric parameters in different subtypes of acute angle closure and compared to fellow eyes of AAC and PACS eyes. METHODS This is a retrospective chart review study. A total of 167 eyes (96 patients) consisting of 71 AAC eyes, 71 fellow eyes of AAC, and 25 PACS eyes were recruited. All patients underwent ocular examination and biometry. The mechanism of AAC was...

PURPOSE To describe the relationship of refractive errors and axial ocular dimensions and age-related cataract. METHODS Population-based, cross-sectional survey of ocular diseases among Chinese men and women aged 40 to 81 years (n = 1232) living in the Tanjong Pagar district in Singapore. As part of the examination, refraction and corneal curvature were determined with an autorefractor, with ...

purpose: to evaluate residual refractive errors after cataract surgery and its determinant factors at farabi eye hospital, tehran. methods: simple random sampling was done among cataract surgery scheduled patients over a 4 year period (2003-2006). exclusion criteria were uveitis, previous intraocular surgery and ocular trauma. after applying the exclusion criteria, 423 patients were studied. le...

Many risk factors have been linked to retinal vein occlusions (RVOs) whether central or branch retinal vein occlusion. Ocular risk factors include glaucoma and hypermetropia. Controversy exists to whether short axial length is a risk factor for retinal vein occlusions. We report an extreme case that supports the latter hypothesis. A 33-year-old male presented with decreased visual acuity in the...

Purpose To investigate the relationship between lens power and age as well as the relationship between lens power and axial length (AL) in Chinese children and adolescents. Methods The participants underwent a comprehensive ophthalmic examination that included AL, cycloplegic refraction, and Pentacam measurements. The crystalline lens power was calculated using Bennett's formula and then comp...
