Anterior segment OCT imaging in cases of episcleritis and scleritis
The purpose of this study was to determine whether it is feasible to obtain good-quality images with anterior segment OCT (AS-OCT) in patients with episcleral or scleral inflammation located anterior to the equator, and whether this technique is able to...
OCT measures of lateral and medial recti
The authors assessed the agreement of the measurements of the horizontal rectus muscle insertion distance to the limbus and the muscle thickness between three different OCT devices. This was a cross section observation study of 70 eyes of 35 subjects....
OCT positioning regimen in macular hole surgery
The authors set out to evaluate an OCT-based positioning regimen for macular hole surgery. Patients were advised to maintain prone positioning until the hole was confirmed to be closed based on daily OCTs. Surgery consisted of 23-gauge phacovitrectomy with internal...
OCT measurements of eye muscles for Grave’s disease
The purpose of this study was to use optical coherence tomography (OCT) to assess horizontal rectus muscle thickening in patients with active and inactive Grave’s ophthalmopathy (GO) compared to healthy controls. This was a cross section observation study of rights...
Comparison between findings in OCTA and FA in patients with diabetic retinopathy
In this study the authors present a prospective cross-sectional comparative study of typical findings of diabetic retinopathy to analyse the agreement between the image modalities of optical coherence tomography angiography (OCTA) and fluorescein angiography (FA). Fifty-three eyes of 42 patients...
OCT biomarkers in asymmetric anti-VEGF response in bilateral diabetic macular oedema
This study aimed to identify optical coherence tomography (OCT) biomarkers for predicting response to anti-VEGF treatment in diabetic macular oedema (DMO). Bilateral DMO patients with asymmetric response to a loading dose of anti-VEGF (ranibizumab / aflibercept) treatment were retrospectively studied....
Does religious fasting affect intraocular pressure or retinal parameters?
Nearly one billion Muslims fast every year during the month of Ramadan. Due to the difference between the lunar and solar calendars, religious fasting time can range from 11 to 17 hours per day. This prolonged abstinence from food and...
Corneal and astigmatic changes after medial rectus recession surgery of 6mm
This study prospectively compared changes in astigmatism before and two months after unilateral recession of medial rectus muscles using Pentacam. The fellow unoperated eye was used as the control eye. The study included 66 eyes and 33 patients; 21 males,...
