Improved efficacy expected with second-generation microinvasive glaucoma surgery (MIGS) devices

Microinvasive surgical approaches to primary open-angle glaucoma (POAG) offer minimally traumatic options for effective intraocular pressure (IOP) reduction in appropriately selected glaucoma patients. Increases in laser trabeculoplasty rates and wider adoption of glaucoma drainage device filtration procedures, together with the...

Investigation of PAX7 positive satellite cells in extraocular muscle surgery

PAX7 is a transcription factor and is expressed in non-active and activated satellite cells. It is needed for muscle progenitor function, survival and expansion. This study investigates the effect of recession/resection surgery on PAX7-positive satellite cells in extraocular muscles of...

Glaukos Launches iStent infinite® in the UK Following MDR Approval

Glaukos has announced the launch of its latest glaucoma treatment, iStent infiniteĀ®, in the UK market after securing approval under the European Medical Device Regulation (MDR). This new approval process is rigorous and provides ophthalmologists with reassurance regarding the efficacy...

Educational concerns and anxiety levels amongst ophthalmology trainees during the COVID-19 pandemic

How concerned are ophthalmology trainees about the present impact and the future consequences of suspended ophthalmic training programmes? Researchers in the West of Scotland investigate. Anxiety, stress and the longer-term stress reaction of burnout often go unrecognised, yet are known...

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...

Abducens nerve palsy following surgical correction of craniosynostosis

The authors present two cases of unilateral abducens palsy secondary to a recent trans-sutural distraction osteogenesis (TSuDO) operation for craniosynostosis. The basic principle of the TSuDO procedure is described as dissection and distraction of the prematurely fused sutures. This complication...

Glasses or not?

In this excellent review article, the authors discuss how some hyperopes avoid strabismus but also ask why the youngest infants escape strabismus and older patients go on to decompensate. The review considers a number of related aspects and their inter-relations...

Modification of surgery to reduce consecutive ET

Surgical treatment for recurrent exotropia (ET) predominantly depends on the primary surgery. Modification of surgical dose may be required in secondary procedures. The aim of this study was to compare surgical outcomes of modified and conventional secondary surgery using lateral...

DVD angle measurements

Surgical treatment for recurrent exotropia (ET) predominantly depends on the primary surgery. Modification of surgical dose may be required in secondary procedures. The aim of this study was to compare surgical outcomes of modified and conventional secondary surgery using lateral...

Allergic conjunctivitis evaluation by thermography

Thermography is a non-invasive imaging technique, which uses infrared radiation reflected from an object to estimate the temperature of the object. This paper evaluates the use of thermography to assess allergic conjunctivitis objectively, by using an instrument called ocular surface...

Changes in corneal endothelial layer after strabismus surgery

The purpose of this study was to investigate the changes in the corneal endothelial layer by specular microscopy after surgery in patients with horizontal and oblique strabismus. Eighty-three eyes of 56 patients were evaluated prospectively. There were three subgroups: one...

Risks to visual function from blepharokeratoconjunctivitis

This study evaluated the prevalence of blepharokeratoconjunctivitis (BKC) and prevalence of amblyopic risk factors with comparison of these rates to rates in the general US paediatric population. The authors evaluated the rate of patient reported symptoms in patients with and...
