Supranuclear ocular motility disorders

Figure 1: Bilateral INO Introduction Complex ocular motility disorders are a diagnostic challenge. These patients come with very complex ocular motility presentations and require a careful and detailed assessment in order to find the correct diagnosis and arrange appropriate investigations....

Perception of depth in 3-D media

The aim of this study was to evaluate the relationship between clinical measures of stereoacuity and the perception of depth in 3-D entertainment media. Fifty-seven subjects aged 16-62 years with stereopsis and no strabismus were assessed. Monocular blur was used...

IOP and reversibility of RPE detachment

The authors describe how three patients with retinal pigment epithelium (RPE) detachment showed a reduction or disappearance of an RPE detachment immediately following prone dark room test (PDRT). The authors performed spectralis OCT on 140 angle closure subjects before and...

Conj reconstruction with amniotic membrane

This study reports the use of amniotic membrane in patients with restrictive strabismus or conjunctiva problems during or following complex eye muscle surgery. Ambio 5 was used for replacement of conjunctiva in this retrospective study of 32 cases aged one...

Retinal vessel diameter in pseudoexfoliation

Pseudoexfolation (PEX) is characterised by deposition of fibrillary extracellular material on ocular and extraocular tissue. Studies have shown that deposition in vascular structures cause hypoxia and ischaemia. In the eye, a decrease in blood supply to the optic nerve can...

Orbital manifestations of granulomatosis with polyangitis

This a retrospective, observational study where authors looked at the ophthalmological examination, biopsy, antibodies and CT scan results of all patients diagnosed with granulomatosis with polyangitis (GPA) from January 2007-January 2019. Out of 101 patients with diagnosis of GPA, 15...

Idiopathic orbital pseudotumor as first sign of systemic inflammatory disease

The authors describe four children in whom idiopathic orbital pseudotumor (IOP) was the initial solitary finding with systemic inflammatory disease developing later. Four children were seen over a five-year period. Mean age was 9.75 years (2-14). Three were white and...

Detecting muscle insertion position by ultrasound

The purpose of this study was to investigate the accuracy to locate muscle insertion positions before and after strabismus surgery using wide-field ultrasound biomicroscopy with the bag / balloon technique. Thirty-nine muscles of 22 adult patients aged 34.7 ±15.5 years...

Prevalence of visual function impairment in congenital ptosis

This study sought to evaluate the prevalence of visual function loss in the setting of congenital ptosis. This was a retrospective study of 155 eyes of 134 patients; 72 males and 62 females. Mean age at diagnosis was 7.8 ±5.8...

Carcinoid tumours

This is a retrospective review of 28 patients with carcinoid tumours affecting the orbit. The mean age at presentation of the orbital involvement was 62 years, with a slight female preponderance, and 21% had carcinoid syndrome. Proptosis and diplopia were...

Rectus muscle insertion shift at surgery

The authors conducted this study to evaluate the shift in rectus muscle insertion when the muscle is disinserted from the globe but before it is recessed and / or transposed. They measured the amount of central rectus muscle insertion shift...
