Comparison of SS-OCT and SD-OCT in polypoidal choroidal vasculopathy

Swept source OCT (SS-OCT) is known to have a longer wavelength than spectral domain OCT (SD-OCT), allowing deeper penetration into retinal and choroidal layers. The aim of this study was to investigate whether SS-OCT is superior to SD-OCT in imaging...

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)...

Update on primary angle closure glaucoma

This review article considers primary angle-closure glaucoma which is responsible for half of glaucoma-related blindness worldwide. Angle closure is characterised by appositional contact between the iris and trabecular meshwork. It tends to develop in eyes with shallow anterior chambers, anteriorly...

First online education day for locum optometrists

The AOP’s online locum day will take place on Sunday 25 June, 09:30-15:45.

Near-infrared autofluorescence to diagnose retinal laser injuries

This retrospective observational case series aimed to assess whether near infrared autofluorescence (NIR-AR) imaging is a useful imaging modality in the diagnosis of hand-held laser retinal injuries. Twelve patients from two centres underwent ophthalmic assessment and retinal imaging including fundus...

Fixation target position for increased limbus measurement accuracy with AS-OCT

The authors intended to determine the optimal gaze fixation points for lateral rectus and medial rectus muscle insertions using anterior segment - optical coherence tomography (AS-OCT) compared with intraoperative measurements. They recorded 46 lateral and 36 medial rectus muscles from...

Presidency changes hands at the International Opticians Association (IOA)

This year saw the baton of the presidency of the International Opticians Association (IOA) handed from Fiona Anderson to Donald Crichton BSc (Hons) FBDO.

Diagnostic accuracy of enhanced depth imaging OCT in children

The authors present the findings of a retrospective cross-sectional case series. Cases were identified using a treatment register having been evaluated in a set one-year period. Two ophthalmologists acted as masked image examiners for enhanced depth imaging optical coherence tomography...

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....

AOP fee reduction for members amidst coronavirus crisis

The Association of Optometrists (AOP) has announced a 20% reduction in membership fees for UK practising members, which is the equivalent of two monthly direct debit payments.

SS-MIOCT for suture depth

The authors describe a case in which swept-source microscope-integrated OCT (SS-MIOCT) was used to directly visualise and evaluate key suturing-related steps of strabismus surgery in real time. Using SS-MIOCT, the surgeons could visualise the precise depth of the needle through...
