OXSIGHT Onyx – A sight-enhancing wearable
The Onyx is a newly-released (late 2021) wearable with a powered magnifier to assist those with central vision impairment. Unlike the previously covered wearable devices, this enhances existing sight. The unit can either be held against the eyes when needed,...Use of off-the-shelf magnifying glasses as a cost-effective alternative for surgical loupes
Surgical loupes are an integral part of ophthalmic surgery on the ocular surface and in the periocular area. Available in different magnifications, they provide a clear view of the field of surgery which can greatly assist in identifying fine structures...Refraction planning in cataract: avoid creating an unhappy patient
“It is much more important to know what sort of a patient has a disease than what sort of a disease a patient has.” William Osler The focus of this paper is the prevention of an unhappy patient following cataract...
Ptosis surgery outcomes
The purpose of this study was to evaluate the long-term outcomes of childhood ptosis surgery in a population-based cohort. The authors assessed reoperation rates, amblyopia, risk of lag, dry eye and other complications. This was a retrospective review of 47...
Comparison of surgical options for basic intermittent exotropia
This study compared the outcomes of three surgical options from one surgeon, to treat basic intermittent exotropia. Surgeries included bilateral lateral rectus recession (BLR), unilateral lateral / medial rectus recession / resection (RR), and unilateral lateral rectus recession and medial...
Comparison of two surgical procedure options for unilateral superior oblique palsy
This study compares two surgical options for management of unilateral superior oblique palsy with angles >20PD. Group 1 underwent one vertical muscle surgery – ipsilateral inferior oblique anterior transposition plus resection (IOATR). Group 2 underwent two vertical muscles surgery –...
How many injections in nAMD: ranibizumab vs. aflibercept
Intravitreal anti-VEGF injections make up a large proportion of the workload in ophthalmology clinics. Since the introduction of aflibercept with eight weekly injections there has been an option to use a treatment which may require less treatment, with potential cost...
Is an increased homocysteine level associated with greater risk of AMD?
Basic research studies have implicated homocysteine in causing vascular endothelial dysfunction and inflammation, and this has been borne out in large observational studies which suggested that elevated homocysteine is associated with increased risk of cardiovascular disease. In order to determine...
Ranibizumab for the treatment of age-related macular degeneration
This multicentre randomised prospective open label study compared 0.5 versus 2mg of ranibizumab in patients with submacular retinal pigment epithelial (RPE) detachment due to age-related macular degeneration. Four treatment regimens were used for the two strengths either monthly for 12...
Detection of antiranibizumab antibodies in exudative AMD
In this study the authors aimed to detect immune response to ranibizumab treatment in wet age-related macular degeneration (AMD). An ELISA was employed to quantify the anti-ranibizumab titre which was compared against the control anti-abciximab titre. Titres of anti-ranibizumab antibodies...
Role of fundus autofluorescence patterns and baseline atrophy area on geographic atrophy progression
Central geographic atrophy (GA) is one of the morphological sub types of late-stage macular degeneration. The natural course of the disease is characterised by expanding areas of macular atrophy, which cause absolute scotoma. Fundus autofluorescence (FAF) is derived from lipofuscin...
