VA and stereo changes with increasing Bangerter filters

This study investigated the effect of monocular blur induced by Bangerter filters (BF) on both monocular and binocular visual acuity (VA) and stereoacuity in normal visual systems. Subjects included 24 healthy student volunteers aged 20.33 ±1.79 years; 22 female. One...

Non-arteritic anterior ischaemic optic neuropathy (NA-AION): a review

Ischaemic optic neuropathy (ION) is the commonest adult optic neuropathy encountered today in our ageing population, is a common cause of irreversible visual loss and is usually associated with underlying vascular disease. The condition is classified as follows: (a) Anterior...

CFEOM outcomes

This study presents the orbital and cranial magnetic resonance imaging (MRI) findings of patients diagnosed with congenital fibrosis of the extraocular muscles (CFEOM) along with the surgical procedures and outcomes for ocular motility and strabismus. Nine patients are described: three...

Review of extraocular muscle biopsies and utility of biopsy in extraocular muscle enlargement

This is a retrospective case series study from Melbourne, Australia, of 93 patients with extraocular muscle (EOM) enlargement who underwent an EOM biopsy between March 1992 and January 2017. Statistical analysis was performed to compare the data between patients with...

Retroauricular myoperiosteal auto graft for orbital implant exposure

In this retrospective, observational study authors reviewed 27 eyes of 27 anophthalmic patients with implant exposure who had received a retroauricular myoperiosteal graft. Their main outcome measure was long-term coverage of implant and the secondary outcome was rate of post-surgical...

Lacrimal gland carcinoma

This is a major review of the management of lacrimal gland carcinoma, focusing mainly on adenoid cystic carcinoma. Relevant literature published in English since 1970 was included amounting to some 40 articles after filtering. Overall mortality for all lacrimal gland...

Occult spread of squamous cell carcinoma into the orbit

The authors describe two cases that may represent perineural spread of cutaneous squamous cell carcinoma (SCC) into the orbit. Both cases had cutaneous squamous cell carcinomas in the region of the lateral orbital wall (innervated by the zygomatico-temporal nerve) which...

An interesting presentation of ruptured anterior communicating artery aneurysm with acute monocular vision loss

The authors report an interesting case of a 60-year-old man presenting with acute monocular vision loss accompanied by periorbital pain as an unusual presentation of subarachnoid haemorrhage (SAH) from ruptured anterior communicating artery aneurysm. The patient did not present with...

Laser pointer maculopathy

The objective of this study was to describe the potential clinical presentations of retinal pathology resulting from exposure to laser pointers. The study included eight eyes of seven patients. Mean age was 18.7 years (12-36). Most were accidental self-inflicted while...

Adolescent optic disc haemorrhages

The authors conducted this study to describe the clinical characteristics of multi-layered optic disc haemorrhages in adolescents. This was a retrospective review of 16 eyes (11 right and five left) of 16 patients with a mean age of 15 ±2.6...

Neuroanatomical structures and eye movements

The aim of this study was to review and critically discuss the role of ocular proprioception in oculomotor control and development of eye motility disorders. The authors considered proprioception, structure and proprioceptors of eye muscles, singly and multiply innervated muscle...

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...
