Two‐year changes of macular choroidal thickness in response to 0.01% atropine eye drops: Results from the myopia outcome study of atropine in children (MOSAIC) clinical trial

Acta Ophthalmologica, EarlyView.
Abstract Purpose To investigate 2‐year changes in macular choroidal thickness (ChT) in children receiving 0.01% atropine eyedrops and its relationship with spherical equivalent refraction (SER) progression and axial length (AL) elongation. Methods A total of 250 myopic children aged 6–16 years (167%–0.01% atropine, 83‐placebo) were enrolled in the ...

A geometric basis for measurement of three-dimensional eye position using image processing [PDF]

, 1996
Polar cross correlation is commonly used for determination of ocular torsion from video images, but breaks down at eccentric positions if the spherical geometry of the eye is not considered.

Scleral suture-fixated intraocular lens explantation [PDF]

Eye, 2014
Sir, Scleral-sutured intraocular lens (IOL) implant is one of the common methods for correction of aphakia in eyes without adequate capsular support.1 Scleral-sutured IOLs can, however, be associated with a variety of complications that sometimes lead to the need for explantation of the implant.2 Although many reports describe insertion ...

Choroidal changes and association with Gaussian curvature in high myopic eyes with posterior staphyloma in ultra‐wide‐field optical coherence tomography angiography

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate choroidal changes in high myopic (HM) patients with posterior staphyloma (PS) and explore their association with Gaussian curvature (K) using ultra‐wide‐field optical coherence tomography angiography (UWF‐OCTA). Methods HM patients with wide macular PS (Type I PS) and without any PS (control) were recruited.

Magnetic Resonance Imaging of Optic Nerve Traction During Adduction in Primary Open-Angle Glaucoma With Normal Intraocular Pressure. [PDF]

, 2017
PurposeWe used magnetic resonance imaging (MRI) to ascertain effects of optic nerve (ON) traction in adduction, a phenomenon proposed as neuropathic in primary open-angle glaucoma (POAG).MethodsSeventeen patients with POAG and maximal IOP ≤ 20 mm Hg, and
