Heidelberg Retina Flowmeter, retinal blood flow, retinal vessel analyser, retinal vessel diameter
This study examined the changes in retinal blood flow and vessel diameter after IOP reduction in high- and low-pressure glaucoma; exfoliation glaucoma (ExG) and normal-tension glaucoma (NTG). Glaucoma progression is seen at times in eyes despite IOP reduction and changes...

CRAO, Central retinal artery occlusion, OCT, RAO, optical coherence tomography, retinal artery occlusion, spectral-domain optical coherence tomography
Central retinal artery occlusion (CRAO) is a sight-threatening condition resulting from occlusion of the central retinal artery and hypoperfusion of the inner retina. Early on, fundal examination may be normal. The authors present a retrospective case series of 11 patients...
OCT Angiography in Retinal and Macular Diseases
OCT angiography (OCT-A) is based on the concept that in a static eye, the only moving structure in the fundus of the eye is blood flowing through the vessels. This book explains how the technique allows a depth-resolved analysis and...Association of pendular waveform and retinal disorders

Nystagmus, nystagmus waveform, retina disorders
The authors aimed to evaluate the relationship between retinal disorders and pendular low amplitude high frequency components (PLAHF) waveform by collecting nystagmus eye movement recordings, electroretinography (ERG) and gene tests. Retinal disorders were diagnosed by clinical phenotype and genotype characteristics....
Migraine and risk of retinal artery occlusion

Retina / Uvea / Vitreous
This retrospective cohort study assessed whether migraine was associated with an increased risk of retinal artery occlusion. They reviewed a large insurance database of 418,965 patients who suffered with migraines between 2007 and 2016. These were then matched with an...

Apoptosis, Large retinal ganglion cells, Neuroprotection, Optic nerve crush, Programmed cell death-1
Death of retinal ganglion cells (RGC) in conditions like glaucoma leads to permanent visual loss. RGC death can be due to the initial stress such as raised intraocular pressure or secondary to mechanism such as oxidative stress. Programmed cell death-1...

Retina / Uvea / Vitreous
Confocal adaptive optics (AO) technology has enabled cellular level retinal imaging, including imaging of photoreceptors and blood flow. Adaptive optics scanning laser ophthalmoscopy (AOSLO) is a technology that provides high resolution and high contrast retinal images by correcting ocular aberrations....

Diplopia, binocularity, botulinum toxin, fusion, retinal surgery
The authors report updated experience on factors influencing botulinum toxin (BT) outcomes for strabismus following retinal detachment surgery. This was a retrospective review of 32 patients with follow-up of 20 months (1-132). Mean age at BT injection was 44 years...

Ganglion cell layer, Hydroxychloroquine, Optical coherence tomography, Retina, Retinal thickness
In this retrospective longitudinal study, the authors examined changes in retinal layer thickness in patients taking hydroxychloroquine without evidence of retinopathy. Patients were drawn from a hydroxychloroquine screening clinic and required at least two OCT scans, at least one year...

Air toxicity, internal gas tamponade, pars plana vitrectomy, pneumoretinopexy, retinal pigment epithelium
This study investigated the potential toxic effects of air on primary human retinal pigment epithelial (RPE) cells in vitro. Clinically during pars plana vitrectomy air is used as either a temporary tamponade during air-fluid exchange or mixed with gas to...
