OCTA to measure surgical hemodynamic changes

This study used the optical coherence tomography angiography (OCTA) technique to evaluate possible hemodynamic changes after horizontal rectus muscle surgery in 32 eyes of 16 patients; nine male, seven female. Recession / resection surgery was undertaken for two horizontal rectus...

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...

Macular measurements for amblyopic eyes

This study aimed to evaluate the macular parameters including foveal avascular zone (FAV) size and vessel density in amblyopia vs fellow eyes. The study included 23 unilateral amblyopia children (9.86 ±3.12 years; 52.2% female) and non-amblyopia control eyes (8.67 ±2.06...

OCTA FAZ measurements in vein occlusion

Previous studies have confirmed that foveal avascular zone (FAZ) enlargement is correlated with visual acuity impairment in patients with retinal vein occlusion (RVO). This current study aimed to evaluate the OCT angiography parameters: the area of FAZ, foveal and parafoveal...

Risk factors for NTG in a young Korean population

Previously known ocular and systemic risk factors for normal tension glaucoma (NTG) include myopia, peripapillary atrophy, disc haemorrhage, migraine, obstructive sleep apnoea, thyroid disease and cerebral infarction. However, most NTG risk factor studies have examined patients aged 40 years and...

A paediatric case of central retinal artery occlusion following antibiotics and decompression surgery for orbital cellulitis

A round-up of the eye-related hot topics that have been trending over the last few weeks. British man fitted with 3D printed eye Steve Verze of London has required a prosthetic eye for over 20 years. On 25 November 2021,...

Trans-sinus endoscopic removal of retrobulbar air gun pellet within the orbital apex

Injuries to the eye have been widely reported in medical literature due to a variety of mechanisms causing significant morbidity and occasional unexpected mortality for the patient [1]. It is often wrongly assumed that air gun pellets lack this potential....

Retinal ischaemia on OCTA and diabetic retinopathy grade

The authors quite rightly point out that quantification of retinal ischaemia has the potential to serve as a biomarker for diabetic retinopathy disease progression. They set out to investigate the relationship between area of ischaemia on a swept source OCTA...
