Selection of visual field test for detection of pituitary disease

This prospective cross-sectional diagnostic accuracy study compared Octopus semi-automated kinetic perimetry (SKP) and Humphrey static automated central perimetry for detection of neurological visual field loss in patients with pituitary disease. Humphrey central 30-2 SITA threshold programme results were compared with...

The rarebit vision test for macular conditions

Rarebit testing is used to measure low degrees of neuro-visual damage and is available for free on the internet. It consists of a fixed bright light dot presented on a black background. During testing it is presented briefly at different...

Computerised tomography in ocular trauma patients

Ocular trauma can be common in military settings. This retrospective study looked into the relationship between the clinical effects of acute ocular and orbital blast trauma with the findings on computerised tomography (CT). This was a consecutive case series of...

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...

Conjunctival inflammation in glaucoma patients

Numerous studies have demonstrated that topical medications and preservatives used for the management of glaucoma can induce significant histopathologic and inflammatory changes in the ocular surface. This study describes an increased expression of major histocompatibility complex class II antigen HLA-DR,...

Comparison between findings in ‘active’ or ‘healed’ giant cell arteritis

Giant cell arteritis (GCA) is the most common systemic vasculitis in older people and can cause devastating sight loss if untreated. Temporal artery biopsy is often relied upon for diagnosis by ophthalmologists, with a positive biopsy result indicating whether the...

Early postoperative angle for prediction of surgical success for exotropia

In this study, the authors assessed the relationship between the initial postoperative deviation and surgical outcomes in adult exotropia undergoing unilateral lateral rectus recession with medial rectus resection. The study included 93 patients (51 female); 26 with residual exo, 53...

A diagnostic imaging technique for optic pathway tumours

The authors discuss the difficult clinical scenario of patients with deteriorating visual function and an optic pathway lesion. The morbidity associated with biopsy means a highly sensitive and specific imaging technique would be of great value. The authors describe the...

Slanted MR surgery for convergence excess ET

The authors aimed to evaluate the surgical outcomes of bilateral slanted recessions of the medial rectus (MR) muscles in patients with convergence excess esotropia (ET). This retrospective study included 16 patients with a mean age at surgery of 5.6 ±3.05...

Strabismus and binocular summation

The authors conducted a pilot study to investigate the effect of visual noise or background complexity on binocular summation in patients with strabismus. A target embedded in pixel noise was used. The study involved performance of a task detecting a...

Effect of phacoemulsification on trabeculectomy function

Previous studies have reported cataract surgery post trabeculectomy to be detrimental to IOP control. Conversely, other studies have reported phacoemulsification performed before trabeculectomy as a factor for bleb failure. The objective of this retrospective case control study was to evaluate...

Effect of oxygen levels on binocular summation of dark vision

Previous studies have reported conflicting results on the existence of binocular enhancement of dark vision. This study compares monocular and binocular absolute thresholds of dark adaptation in two different populations (healthy individuals and those with chronic respiratory insufficiency). The study...
