EYE - Glaucoma
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...

EYE - Neuro-ophthalmology
This is a retrospective population-based cohort study to evaluate the risk of developing optic neuropathy from the use of amiodarone in Taiwan. Over a five-year period (2005-2009), there were 6175 amiodarone-treated patients with 24,700 patients taken as controls. After a...

Divergence, innervation, oblique muscle, oculomotor nerve, rectus muscle
The authors present a case report of a 14-year-old boy with left ptosis and strabismus since childhood. In primary position he had left hypotropia with ptosis. On elevation of the right eye, the left eye depresses and adducts. Conversely, on...

EYE - Neuro-ophthalmology
We have all had referrals from A&E telling us that a patient can’t see out of one eye. Sleepily we may ask “Is there an relative afferent pupillary defect (RAPD)?” to evaluate the seriousness of the presentation. The response is...

Allergic fungal sinusitis, compressive optic neuropathy, magnetic resonance imaging
The authors present an unusual case report of a 32-year-old man with advanced allergic fungal sinusitis, presenting with severe bilateral visual loss and restricted ocular motility. On presentation he had an 18 month history of progressive nasal obstruction, as well...
Placement of an eyelid weight as an upper lid spacer for lagophthalmos

EYE - Neuro-ophthalmology
Upper lid loading with a weight is a well described procedure for the treatment of lagophthalmos and exposure keratopathy. The authors describe a modification of this procedure whereby the levator aponeurosis is recessed in combination with supratarsal weight implantation. The...
Comparison of central laminar thickness in optic neuropathy and normal eyes
The study compares central laminar thickness (LT) among patients with glaucomatous optic neuropathy (GON), patients with non-GON and normal subjects. The non-GON group comprised eyes with demyelinating optic neuropathy (ON), anterior ischaemic ON, compressive ON, Leber hereditary ON and traumatic...
Light reflex in preterm infants
In this study, the pupillary size and light reflex was examined in premature infants using infrared video-pupillography and stimuli of red and blue light. Only eyes of infants without retinopathy of prematurity were included in the study. Pupillary light reflexes...
A case report of papilloedema caused by unilateral jugular vein thrombosis

Headache, idiopathic intracranial hypertension, jugular vein thrombosis, papilloedema
In rare cases, unilateral jugular vein thrombosis can lead to increased intracranial pressure and papilloedema, resulting in headaches and visual loss. The authors describe the case of a 45-year-old patient with squamous cell carcinoma of the larynx who developed right...
Interesting causes and consequences of orbital inflammations
Three articles discuss various causes and consequences or orbital cellulitis. The first highlights the possibility of orbital cellulitis causing cavernous sinus thrombosis and in the case presented progression to internal carotid artery aneurysm. The authors highlight the importance of considering...

EYE - Glaucoma
This is a masked study of 33 patients who had been taking a prostaglandin analogue in one eye only for at least a year, to look for signs of prostaglandin-associated periorbitopathy (PAP). The investigators devised a new grading system to...
