Divergence insufficiency esotropia is increasingly more common and new theory of aetiology

The authors present a retrospective case review of acquired esotropia. An internal database was reviewed for cases of esotropia and divergence insufficiency between 1978 and 2018 and seen by a single ophthalmologist. Patients with initial presentation of esotropia onset after...

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,...

BESTi: a new index to detect subclinical keratoconus

In this multicentre, case-control study, the authors develop a new index, named Boosted Ectasia Susceptibility Tomography Index (BESTi), to detect early cases of keratoconus. This index was derived from multiple logistic regression analysis of 22 variables of tomography scans. The...

Glaucoma specialist takes on Everest Skiing Challenge

Consultant ophthalmologist and surgeon, Nishani Amerasinghe, took on the 2023 Everest in the Alps challenge from 28 February 2023 to 3 March 2023, to raise money for Glaucoma UK to help end preventable glaucoma sight loss.

Eyelid lesions and excision results

This was a retrospective study of 137 consecutive, non-chalazion, paediatric eyelid lesions excised between 2013-2020. Mean age at diagnosis and excision was 8.24 years (four months to 18 years) and 55.1% were female. Benign non-cystic epithelial lesions accounted for about...

Preterm birth and refractive error in an Indian infant population

This study was undertaken to identify and compare the changes in refractive outcome in infants with and without retinopathy of prematurity (ROP), to inform incidence of refractive error. This was a prospective study of 300 consecutive premature infants with birth...

Cycloplegic autorefraction versus cycloplegic retinoscopy

This cross-sectional study compared cycloplegic autorefraction using VISUREF 100 table top and keratometer device (Zeiss) versus cycloplegic retinoscopy. The study included 47 children (94 eyes) of which 55 eyes were excluded because of ocular disease or not aged three to...

Differences in elastometry of cornea and optic nerve head in both eyes of patients with NAION

Non-arteritic anterior ischaemic optic neuropathy (NAION) is an important cause of visual loss in the middle aged and elderly population. This prospective cross-sectional study investigates the biomechanical properties of optic nerve head (ONH) and cornea in both eyes of patients...

Under pressure: intraocular pressure and bariatric surgery

Obesity in the general patient population is increasing. The National Institute for Health and Care Excellence recommends bariatric surgery with body-mass index (BMI) of over 40, or between 35-40 and other significant disease that could be improved with weight loss....

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)...

Normative dimensions of the lacrimal gland

This article looks at the normative dimensions of the lacrimal gland in the axial and coronal plane on fat-suppressed T1 weighted contrast-enhanced magnetic resonance imaging (MRI). Previous data on this subject has come from computed tomography (CT). MRI is known...

Case reports of neuro-visual consequences of mild COVID-19 in children

Neuro-visual involvement has been reported in numerous patients with severe SARS-CoV-2 disease, mainly among adult patients. In children, such involvement has been reported in rare cases, often in those presenting with severe forms of COVID-19. The aim of this work...
