Amplitude, latency, pupillary light reflex pathway, pupillometer, retrograde trans-synaptic degeneration
It has been reported that relative afferent pupillary defects (RAPDs) may be present in patients with occipital lobe lesions. However, a small contralateral RAPD due to a difference in the crossed and uncrossed fibres can be difficult to detect using...

Foveal displacement, internal limiting membrane peeling, metamorphopsia, papillofoveal distance, temporal inverted internal limiting membrane flap
Previous studies show that internal limiting membrane (ILM) peeling during macular hole surgery is associated with retinal shrinkage (microtubule depolymerization of the axons of the inner retina) and nasal shift of the fovea. A temporal inverted ILM flap technique was...

Huntington disease, King-Devick test, contrast sensitivity, eye movements, saccades
This study aimed to evaluate afferent and efferent visual function in Huntington’s disease (HD). HD is often portrayed by abnormal saccadic eye movements and afferent visual pathway involvement however these are poorly characterised and difficult to quantify at the bedside....
Headaches in ophthalmology (part 2)
Ophthalmologists see a large number of patients with headaches or facial pain in the ophthalmic outpatient clinics or in emergency clinics. Over two articles, I will discuss several causes of headaches, ocular manifestations and proposed management and referral options. It...A glossary
After a week on call grading what feels like 13 billion referrals I decided it might be useful to come up with a glossary that might help other people in some way to decipher the true meaning behind every repetitive...What not to miss in neuro-ophthalmology Part 2

EYE - Neuro-ophthalmology
As mentioned previously there are several conditions in neuro-ophthalmology that should not be missed by the general ophthalmologist as well as ophthalmology trainees. We discussed in the first part some of these conditions including third cranial nerve palsies, giant cell...

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...
