Choroidal and macular thickness in nonarteritic anterior ischaemic optic neuropathy

This study evaluates the choroidal and macular thickness in patients with chronic nonarteritic anterior ischaemic optic neuropathy (NA-AION). Two groups of subjects were compared, group one included 20 eyes with chronic NA-AION and group two, 31 healthy control eyes. The...

Choroidal thickness in ocular sarcoidosis by OCT measurement

This is the first study to evaluate the choroidal thickness in patients with ocular sarcoidosis during the quiescent phase using enhanced depth imaging optical coherence tomography (EDI-OCT) and comparing with normal subjects. Ocular sarcoidosis may affect the choroidal circulation (occlusive...

Visual fields and OCT in hydroxychloroquine retinopathy

It has been recommended that patients on hydroxychloroquine be monitored regularly for retinopathy. However, there has not been an agreement as to the best screening test for hydroxychloroquine toxicity, which may include visual fields (VF), fundus autofluorescence, spectral domain optical...

Clinical course of vitreomacular adhesion managed by initial observation

The purpose of this study was to investigate the clinical course of patients with idiopathic vitreomacular adhesion (VMA) with a noncomparative case series of patients who had clinical symptoms and spectral-domain optical coherence tomography findings consistent with VMA. The VMA...

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...

Density of cataract and its influence on retinal nerve fibre layer thickness

The aim of this study was to further define and model the influence of cataract on spectral domain optical coherence tomography (SDOCT) image quality and retinal nerve fibre layer (RNFL) thickness measurements. OCT quality is influenced by opacities in the...

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)....

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 angiography and retinal vein occlusions

In this retrospective, observational case series, the authors set out to evaluate the morphology of the superficial and deep capillary plexa of eyes that suffered a retinal vein occlusion (RVO) on OCT angiography (OCTA) and compare the findings with fluorescein...

Swept-source OCT for measuring peripheral anterior synechiae

The authors report on a cross-sectional study looking at swept-source optical coherence tomography (SS-OCT) for measuring the area and degree of peripheral anterior synechiae (PAS) in patients with angle closure glaucoma. The SS-OCT is commercially available, has a laser wavelength...

OCT changes in chronic optic neuropathy

The authors evaluated optical coherence tomography (OCT) angiography in 10 patients who suffered various types of chronic optic neuropathies. Glaucoma is known to cause a decrease in peripapillary perfused capillary density on OCT angiography. However, other optic neuropathies have not...

What's trending Oct/Nov 2021

A round-up of the eye-related hot topics that have been trending on social media over the last few weeks. #cataracts #holography #simulation Cataracts are the major cause of blindness globally and innovating novel management strategies remains as important as ever...
