Pseudostrabismus leading to strabismus

The authors aimed to evaluate the incidence of strabismus in children initially diagnosed with pseudostrabismus and identify risk factors for development of strabismus. This was a retrospective review of 65 patients with a diagnosis of pseudostrabismus; two exo and 63...

Characteristics and incidence of sixth nerve palsy in children with intracranial hypertension

The authors report the incidence and characteristics of sixth cranial nerve palsy in paediatric patients with intracranial hypertension. A retrospective review of records was performed in central Ohio over a three year period and nine children were found to have...

An unusual case of partial oculomotor nerve palsy

The authors present an unusual case of intra-axial oculomotor nerve involvement due to midbrain infarction. The 65-year-old male patient presented with unilateral complete blepharoptosis and slight limitation of upgaze. Neurological examination revealed a complete ptosis of the left eyelid, slight...

Resveratrol protects against steroid induced intraocular pressure

Topical and systemic steroid delivery is a very effective treatment for many ocular conditions but is compromised by raised intraocular pressure which in turn leads to death of retinal ganglion cells and irreversible blindness. This is an important consideration with...

Syndromic V-pattern management

The authors document their experience in the management of four cases of Crouzon syndrome and review the anatomical extraocular muscle anomalies noted during surgery. Horizontal strabismus surgery varied in each of the four cases according to individual extraocular muscle abnormalities...

Familial Mediterranean Fever and keratoconus

This retrospective case control study was conducted in the Genetic Diagnostic Centre in Turkey. It examined the prevalence of keratoconus in two groups; patients with Familial Mediterranean Fever (FMF) and age matched controls free of FMF, who were tested for...

Anterior segment OCT predicts gonioscopic angle closure

This is a prospective observational study of 342 subjects over four years. Sixty-five were controls who had open angles both on gonioscopy and AS-OCT, while 277 had open angles only on gonioscopy but iridotrabecular contact (ITC) on AS-OCT (one to...

PD-1 and retinal ganglion cell death

Death of retinal ganglion cells (RGC) in conditions like glaucoma leads to permanent visual loss. RGC death can be due to the initial stress such as raised intraocular pressure or secondary to mechanism such as oxidative stress. Programmed cell death-1...

Early diagnosis of pituitary apoplexy using combined MRI findings

The author presents a literature review searching the terms ‘pituitary ring sign’ and ‘sphenoid sinus mucosal thickening’ in the context of pituitary apoplexy from 1990 until the present day. These two findings are both magnetic resonance imaging (MRI) signs of...

Somatostatin protects retinal pericytes

Diabetic retinopathy (DR) is a complication of diabetes, caused by high blood sugar levels damaging the retinal microvasculature. Mechanisms, such as oxidative stress and deposition of advanced glycation end products, leads to glial cell activation and neuronal apoptosis. Pericytes, contractile...

Influence of overall intraocular lens diameter on rotational stability

It has been shown that approximately one in three patients undergoing cataract surgery have >1.0D corneal astigmatism and managing this during surgery is important to achieve good refractive outcomes. One of the widely used ways of reducing preoperative astigmatism during...

Nicotine accelerates diabetes induced retinal changes

This study investigated the influence of nicotine in an experimentally induced diabetic rat model. They used non-invasive high-resolution spectral domain optical coherence tomography (SD-OCT) imaging to provide quantitative information on the temporal alterations of retinal structures at the micrometer resolution...
