Orbital cavernous haemangiomas

This is a review of orbital cavernous haemangiomas (orbital cavernous venous malformations) managed over a 12-year period at a tertiary referral centre. Painless proptosis was the commonest presentation. One hundred and sixty-four patients (96 female and 68 male) underwent surgery...

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...

Ocular adnexal mantle cell lymphoma

In this study the authors compare primary ocular adnexal (OA) mantle cell lymphoma (MCL) with initially systemic MCL occurring over a 30-year period. MCL is a rare form of lymphoma accounting for 5-11% of OA lymphomas and therefore knowledge of...

Yolk sac tumours of the orbit and sinonasal tract

Intermittent manual compression for CCF

Carotid cavernous fistulae (CCF) can be classified as high and low-flow or as having direct and indirect communication. Most commonly, management of high-flow CCF is with endovascular embolisation. The authors look at an alternative treatment for CCF in indirect low-flow...

Effects of orbital decompression on duction, cyclotorsion and diplopia

This is a retrospective review of 156 patients (281 eyes / orbits) with Graves Orbitopathy (GO) who had orbital decompression (OD) between 2016 and 2020 from Amsterdam, Netherlands. Data analysis of type of OD, eye position, duction, cyclotorsion and level...

How common are carotid-cavernous fistulas and what are the neuro-ophthalmic manifestations?

The authors present a retrospective study using the Rochester Epidemiology Project database. The aim was to establish the incidence of carotid-cavernous fistulas (CCF) and outline the associated neuro-ophthalmic patterns. Cases were identified from the database using the following criteria: a...
