Retinal microvasculature in amblyopic eyes

This study evaluated and compared measurements of macular vessel density and foveal avascular zone using optical coherence tomography (OCT) angiography in amblyopia eyes and age-matched controls to determine whether results are in agreement with previous studies. This was a cross...

OCT angiography findings in amblyopic eyes

In this study, optical coherence tomography angiography (OCTA) was used to detect the existence of any vascular dysfunction in superficial and deep retinal layers that accompany visual impairment in amblyopic eyes compared to fellow and control eyes. The study included...

From Dye to Digital: Why OCTA is replacing invasive imaging in retinal care

For decades, retinal imaging has relied on invasive dye based techniques to visualise the eye’s vasculature. However, Optical Coherence Tomography Angiography (OCTA) is fast becoming the preferred modality, replacing fluorescein and ICG angiography in many clinical settings. As highlighted by...

Short-term effects of atropine measured by OCTA for myopia progression

This was a prospective observation cohort study to evaluate the effect of atropine on axial length (AL), choroidal thickness and choroidal stromal volume (CSV) using swept-source OCT angiography (OCTA). The study included 26 subjects of which 25 had sufficient quality...

Association between neurodegeneration and macular perfusion in the progression of diabetic retinopathy

In this prospective three-year longitudinal study, the authors aimed to explore the relation between retinal neurodegenerative changes and vessel closure (VC) in individuals with non-proliferative diabetic retinopathy (NPDR). The participants included 74 individuals with type 2 diabetes, NPDR, and Early...

Retinal Vein Occlusions: Evidence-based Management

This reference book is designed to enable an ophthalmologist to make diagnostic and treatment decisions on the basis of the available scientific evidence. This is a very comprehensive book covering all aspects of central retinal vein occlusions including basics, clinical...

“Herr Doktor, I can’t see but I am driving”

This 56-year-old lady was quite puzzling. With her own glasses and the pinhole she merely managed to see the 1.3 and 1.0 logMAR lines with her right and left eye, respectively (I am currently working in Germany again, so goodbye...

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...

Eyelid position assessment using mobile phone photography and simple measurement tool in children

Inspired by the difficulty to obtain the gold-standard measurement of eyelid position in children, the authors present a proof-of-concept study of a simple measurement tool paired with digital photography. Patients and their siblings between the ages of one-year to 21-years-old,...

Can OCT predict Alzheimer’s disease?

Simerdip Kaur takes a look at the latest ophthalmology-related news stories and asks which are based on facts and which are ‘fake news’. Headline: Can OCT predict Alzheimer’s disease? In 1986 Hinton et al. demonstrated evidence of optic nerve degeneration...

My Top Five: Innovations in the diagnosis of ocular tumours

Ocular tumours can vary widely in origin, from benign growths to metastases from distant disseminated malignancies. Although rare, ocular tumours pose a significant health and economic burden globally, with ocular cancers accounting for 0.2% of all diagnosed malignancies in the...

Effect of long-term RGP-CL wear on keratoconus progression

This is a retrospective study between April and December 2017, of 22 rigid gas-permeable contact lens (RGP-CL) patients (31 eyes) and 15 non-CL patients (20 eyes) who fulfilled the criteria of: 1) >3 years follow-up and 2) Scheimpflug-based corneal imaging...
