Binocular summation, dark adaptation, monocular vision, neural summation, probability summation
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...

Abducens nerve palsy, carotid-cavernous fistula, transvenous embolisation
This report presents two cases of abducens palsy developing with late onset following endovascular treatment for carotid-cavernous fistula. Following this common and effective treatment for carotid-cavernous fistula, an immediate cranial nerve palsy is a common finding. It usually resolves spontaneously....

EYE - Neuro-ophthalmology
The authors investigated the effect of ethnicity and gender on optic nerve head morphology comparing Indian and Caucasian males and females. The optic nerve head was investigated using spectral-domain optic coherence tomography (SD-OCT). Results showed that disc and rim areas...
A mouse model for uveal melanoma
Uveal melanoma (UM) is the most common malignant tumour arising within the eye and is a severe threat for both sight and life, due to a high risk of metastasis. There are no animal models of UM, but the Tg(Grm1)...
A tarso-conjunctival flap for paralytic ectropion
This is a review of 110 patients with paralytic ectropion who underwent a lateral tarso-conjunctival flap procedure. The technique involves fashioning a 4-8mm wide lateral tarso-conjunctival flap in a similar way to a lateral Hughes flap. This is then sutured...
The presentation of natural killer / T cell lymphoma to the oculoplastic surgeon
The authors present three cases of periorbital extranodal natural killer / T cell lymphoma (ENKL). Ages were 20, 45 and 55. All of these patients presented with painless eyelid swelling and a history of sinus disease. One patient had persistent...
