Caring for adults with an ocular tumour

Detection If you screen for an intraocular tumour, dilate the pupil. If the patient is driving, use phenylephrine only. If the patient declines, document this in the casenotes. Don’t forget to look for sentinel vessels, which would indicate a ciliary...

OCTA in angioid streaks

This paper reports on the optical coherence tomography angiography (OCTA) features of choroidal neovascularisation (CNV) secondary to angioid streaks and the ability to predict CNV activity. A total of 38 eyes of 19 patients were included in the study. Thirty...

Nerve head in healthy humans using OCT-angiography

Optical coherence tomography angiography (OCT-A) is a recent, dyeless, and noninvasive imaging technique for evaluating depth-resolved vascular status by capturing the dynamic motion of the erythrocytes. It provides the flow map of major vessels and capillary plexuses separately in different...

OCT angiography in PAMM secondary to CRVO

Paracentral acute middle maculopathy (PAMM) is a recently described manifestation presenting with hyperreflective bands within mid retina on spectral domain optical coherence tomography (SD OCT). The current view is that these findings are markers of ischaemia of deep retinal circulation....

25 years of OCT

David Huang first described optical coherence tomography (OCT) in 1991, in his seminal paper on the subject in Science. This method developed the work of others on ophthalmic interferometry, which essentially showed that measuring reflected light could be used to...

Topography based keratoconus progression after corneal collagen cross-linking

Case 1 describes a 35-year-old man with progressive keratoconus (PK). His best corrected visual acuity (BCVA) was right 20/80 (-5.25/-7.75 x 85) and left 20/20 (+4.75/-5.00 x 90). His Ks were right 36.32/48.02 D and 41.15/46.41 D. Right central cornea...

Using video-oculography to record monocular eye movements

The aim of this study was to examine the characteristics of monocular eye movements recorded using video-oculography (VOG). VOG monocular recording has become increasingly popular in comparison to electro-oculographic binocular recording, due to its simple technique. The authors evaluated the...

A case of post-viral ocular microflutter

A number of eye movements disrupt visual fixation, one such movement being saccadic intrusions which are described as small involuntary saccadic movements. Among saccadic intrusions without intersaccadic intervals, ocular flutter and opsoclonus are prominent. When the saccadic amplitude is very...

Atlas Optical Coherence Tomography of Macular Diseases and Glaucoma

The book is divided into three sections: an introduction to optical coherence tomography (OCT), the OCT in macular diseases, and glaucoma. The first section lists the currently commercially available OCT machines, then describes the techniques for acquiring OCT images using...

Does lower eyelid entropion repair alter corneal topography?

The authors aimed to analyse the corneal morphology before and after advancement of posterior lower eyelid retractors (LERs) alone or in combination with a lateral tarsal strip (LTS) for lower eyelid involutional entropion. Retrospective analysis of 24 consecutive elderly patients...

Neovascular AMD: fresh recommendations underline standards of best practice

The management of neovascular age-related macular degeneration (nAMD) has advanced dramatically over the past seven years, with the introduction of targeted new therapies that successfully maintain or improve vision in a majority of affected individuals. It’s a fast moving field,...

Cataract surgery and circadian photoentrainment

The study authors sought to investigate the possible effects of circadian photoentrainment following cataract. This was a randomised clinical trial, where 76 eyes of 76 patients (with bilateral cataract) were randomised to blue-blocking or neutral intraocular lenses (IOLs). Outcome measures...
