Scheimpflug vs. OCT in measuring corneal thickness

The authors report on the reproducibility and repeatability of corneal thickness measurements using three different Scheimpflug imaging cameras (Pentacam, Sirius and Galilei) and one Fourier-domain optical coherence tomography (OCT) system (RTvue-100). The rationale for this study is that corneal thickness...

Time domain vs. spectral domain in the measurement of the optic nerve head

The authors describe a prospective study of 40 participants (20 healthy and 20 with glaucoma) enrolled to compare the measurements of the optic nerve head (ONH) parameters given by time domain (TD) and spectral domain (SD) optical coherence tomography (OCT)....

Macular pigment and dark adaptation in older population with normal maculas

Macular pigment (MP) such as lutein, zeaxanthin and meso-zeaxanthin are highly concentrated in the fovea. They protect the retina from damage of ambient blue light via antioxidant properties. In older eyes with normal healthy retina, macular pigment optical density (MPOD)...

Optical coherence tomography angiography usability in measuring iris vasculature in strabismus surgery

The purpose of this study was to investigate the use of optical coherence tomography angiography (OCTA) as a screening tool for anterior segment ischemia (ASI) in strabismus surgery. Optical coherence tomography angiography measurements were taken in 18 subjects. Twelve were...

Abdul Muhyemin Tarin reviews the presentation, pathophysiology and management of this paraneoplastic syndrome. Case presentation A 60-year-old hypermetropic female patient presented with several months’ history of painless blurred vision. Visual acuity (VA) was 6/24 and 6/9-1 in right and left...

What’s next in retinal imaging? Faster, deeper and full-on

Fast-evolving technological leaps are opening the way toward clinically useful ocular coherence angiography, generating 3-dimensional microvasculature maps without intravenous dye injection, as well as whole-eye imaging, handheld patient-operated optical coherence tomography (OCT) devices and, for challenging vitreoretinal procedures, integrated intraoperative...

Javier Bardem 'donates' his iris to the Eyes of the World Foundation to fight avoidable blindness

The Eyes of the World Foundation has launched 'Iris of the World' to raise awareness of the deficiencies in eye care in the most vulnerable areas of the world, and to defend the universal right to vision.

Video consultations after COVID-19
