Trial of low-concentration bimatoprost and timolol eye gel versus higher concentrations

This is an international, multicentre, randomised, parallel group, investigator-masked study of 554 patients, having insufficient control of intraocular pressure (IOP) with a first-line monotherapy and requiring dual therapy. Two hundred and eighty patients were randomised to receive low concentration (BTFCEG...

Orbital cellulitis - an overview of the diagnosis and management

Periorbital (preseptal) and orbital cellulitis are infections of the subcutaneous tissues of the eye. They are differentiated by the location of the infection. Periorbital cellulitis refers to infection of the eyelid and subcutaneous tissues anterior to the orbital septum, whereas...

Myasthenia gravis presenting with isolated ptosis: a poorly studied subgroup

Investigation into the cause of one isolated symptom or sign can be challenging if that particular sign may be caused by a variety of pathological processes, affecting different tissues, and presenting to different specialties. Unilateral ptosis is a case in...

Understanding and confronting bacterial endophthalmitis

Abdus Samad Ansari highlights the importance of early recognition of this condition using an unusual presentation. Endophthalmitis is a medical emergency with devastating consequences. Despite adequate treatment, severe cases frequently result in permanent blindness. Endophthalmitis involves inflammation of both the...

Strabismus in thyroid eye disease

Pathogenesis Thyroid eye disease (TED) is an auto-immune condition, in the initial phase there is lymphocytic infiltration and oedema of the extraocular muscles with deposition of glycosaminoglycans and hyaluronic acid and adipogenesis, which can lead to an increase in the...

Serendipity

“Serendipity is looking in a haystack for a needle and discovering a farmer’s daughter” – Julius Comroe Jr (Surgeon, Medical Researcher and Author) One of the attractive features of ophthalmology, apart from the good quality of life and the relatively...

Long-term outcomes of intravitreal ranibizumab for neovascular AMD

This is a single centre prospective study for the long-term, whole population ‘real-world’ clinical outcomes of ranibizumab therapy in treatment-naïve patients for neovascular age-related macular degeneration (AMD). This study recorded: demographics, Early Treatment Diabetic Retinopathy Study visual acuity (ETDRS VA)...

Retinal vascular occlusion from gentamicin injection post-vitrectomy

The authors present two case reports for the rare, but serious, complication of retinal vascular occlusion as a presumed result of subconjunctival injection following 25-gauge vitrectomy. Risk factors for the complication include: cardiovascular disease, retrobulbar anaesthesia, high intraocular pressure (IOP)...

A look into the IOL space

Advances in the design and performance of intraocular lenses (IOLs) continue to be driven by demand for better outcomes, presbyopia correction and spectacle independence, alongside a better understanding of the dynamics of the crystalline lens, newer theories of accommodation and...

RPTP-σ increases pro-MMP activity in a trabecular meshwork cell line following oxidative stress conditions

This study aims to outline the role of phosphatases in the aqueous drainage system by overexpressing receptor tyrosine phosphatase sigma (RPTP-σ) in a human normal trabecular meshwork cell line and describing its effect on subtypes of matrix metalloproteinases (MMP) and...

Grading of ocular inflammation in uveitis: an overview

Anterior uveitis is the commonest form of uveitis, which can lead to severe morbidity if not treated appropriately [1]. Data from general ophthalmology practices suggest around 90% of uveitis encountered by comprehensive ophthalmologists is anterior uveitis [2]. Intermediate (vitreous), posterior...

My Top Five: Emerging robotic and automated innovations in ophthalmological surgery

Robotic technology is redefining the landscape of ophthalmological surgery by enabling micron-level precision and control beyond human capability. Intraocular microsurgery remains challenging to perform, with concerns about accuracy, tremor, precision, depth perception and dexterity. Moreover, conventional surgical tools have only...
