IOL power calculation accuracy in childhood cataract surgery

Refractive outcomes in eyes after vitrectomy vary as the timing of cataract surgery may influence the outcome when done as staged surgery after vitreoretinal (VR) surgery or at the same time as VR surgery. The authors aimed to determine the...

Visual acuity conversion to digital acuity

The author proposes a basic set of evidence-based digital acuities for alpha vision to facilitate formatting of visual acuity data uniformly. This work was informed by a review of the literature. A full table provides US and international classification of...

Clinical outcomes of endoscopic dacryocystorhinostomy

The aim of this study was to report the authors’ experience with endoscopic dacryocystorhinostomy (ED) in a paediatric population and to evaluate the effect of surgical site reassessment on anatomy and clinical outcomes. The study included 47 children <18 years...

Spot screen versus cycloplegic refraction

This study compared the spherical, cylindrical and spherical equivalent values obtained by the Spot screener before and after induction of cycloplegia with the values of cycloplegic refraction to explore the application value of the Spot screener in refractive error screening...

RCT of VR training versus occlusion for amblyopia

The purpose of this study was to compare the visual outcomes of occlusion with game playing through a virtual reality (VR) system in children with unilateral amblyopia. The study was undertaken at the Negah Eye Hospital in Iran. This was...

Pilot trial of virtual reality to treat amblyopia beyond the age of seven years

A pilot double-blind randomised controlled trial is presented. Patients were required to be between seven and 38 years of age, have a diagnosis of anisometropic and / or strabismus unilateral amblyopia, visual acuity in the amblyopic eye between 0.3-1.0 LogMAR...

Retinal findings in COVID-19 patients

This is a single centre cross-sectional study from Brazil between 20 to 23 May 2020, with a total of 18 patients; nine male and median age was 62.5-years-old. 10/18 (55.6%) had retina abnormalities upon dilated eye examination. Flame-shaped haemorrhages were...

Cystoid macular oedema following retinal detachment surgery

There are limited studies examining the incidence and risk factors for postoperative cystoid macular oedema (CMO) following rhegmatogenous retinal detachment (RRD) repair. Postoperative CMO is thought to be due to pro-inflammatory state, where numerous cytokines lead to tight junction dysfunction,...

Foveal displacement after macular hole surgery

Previous studies show that internal limiting membrane (ILM) peeling during macular hole surgery is associated with retinal shrinkage (microtubule depolymerization of the axons of the inner retina) and nasal shift of the fovea. A temporal inverted ILM flap technique was...

Second primary tumours after sebaceous carcinoma

This is a study investigating the risk of developing a second primary malignancy in patients previously diagnosed with eyelid sebaceous cell carcinoma. The records of 559 patients who were diagnosed with sebaceous cell carcinoma between 2000 and 2016 were reviewed,...

Adjuvant radiotherapy in orbital malignancy

This is a retrospective review of high dose volumetric modulated arc radiotherapy (VMAT) for adjuvant treatment of patients with orbital malignancy who had already undergone local excision or exenteration. VMAT differs from conventional external beam radiotherapy in that it is...

How to reconstruct an upper lid defect

In this 10-year review, the authors look at published techniques for repairing upper lid defects and their respective success. Of the 10 studies included in this paper, they divide the techniques described within to bridging and non-bridging. Bridging techniques tend...
