Driving with the use of spectacle mounted telescopes (bioptics)

The authors discuss the current perspectives of spectacle mounted telescopes (bioptics) whilst driving among patients with visual impairment. The history, design and driving laws surrounding the use of bioptics is discussed in detail. In 1977, William Feinbloom developed a bioptic...

Unique case of steroid-induced intraocular pressure spike causing NAION

The literature describes previous cases of nonarteritic anterior ischaemic optic neuropathy (NAION) following rapid rises in intraocular pressure (IOP) leading to reduced optic nerve head perfusion and disruption. This is commonly following ophthalmic procedures, acute glaucoma or steroid eye drops....

Contrast sensitivity in myopic eyes

A classification system has been proposed for myopic maculopathy: grade 0 (no myopic retinal lesions), grade 1 (tessellated fundus), grade 2 (diffuse chorioretinal atrophy (CRA)), grade 3 (patchy CRA), and grade 4 (macular atrophy). Tessellated fundus is defined as the...

Early biomarker for paraneoplastic retinopathy

This informative case series evaluates 4 eyes of 2 patients presenting with rapidly progressive vision loss secondary to cancer-associated retinopathy. The authors identified a distinct spectral-domain optical coherence tomography structural feature termed the angular sign of Henle fibre layer hyperreflectivity...

PDI check Nintendo screening results

‘PDI check’ is a vision assessment game developed for the autostereoscopic upper screen on the Nintendo 3DS XL game console. Version 0.2.5 emphasises quick assessment of monocular acuity, stereoacuity and red-green colour deficiency. The purpose of this study was to...

Non-organic visual loss

Patients can present to eye departments with various signs and symptoms (mostly symptoms) with no obvious organic cause. These patients can be labelled with any of a wide range of diagnoses such as functional visual loss, functional overlay, psychosomatic reaction...

Fusional vergence measurement

This paper reports a systematic review to address two objectives: 1, to compare the normative values of tests measuring fusional vergence; 2, to investigate sources of heterogeneity of prism accuracy. The review was conducted according to PRISMA guidelines with a...

Mediation of vertical vergence

The authors hypothesised that if vertical vergence were mediated by vertical rectus muscles, then the eye that moves during a vertical fusion task would produce larger vertical vergence when abducted versus adducted. Similarly, if mediated by the oblique muscles then...

Trabeculectomy for normal tension glaucoma

This is a retrospective consecutive, non-comparative case series of 131 eyes of 98 patients undergoing trabeculectomy between 2007 and 2013 in a normal tension glaucoma (NTG) clinic. Assessment of the clinical outcomes include intraocular pressures (IOP) reduction, bleb formation, final...

In conversation with Salman Waqar

Hari Kaneshayogan interviews Salman Waqar, a Consultant Ophthalmologist with a keen interest in medical innovation. He is the inventor of the Waqar suture removal forceps, which combines suture cut and removal in one instrument. He has also created an injection...

Strengthening capacity for ophthalmic research within three East African VISION 2020 LINKS – The Research Mentorship Workshop

Building capacity for ophthalmic research in low- and middle-income countries is an important aim of the VISION 2020 LINKS Programme. The International Centre for Eye Health (ICEH) at the London School of Hygiene & Tropical Medicine (LSHTM) has been working...
