Occult spread of squamous cell carcinoma into the orbit

The authors describe two cases that may represent perineural spread of cutaneous squamous cell carcinoma (SCC) into the orbit. Both cases had cutaneous squamous cell carcinomas in the region of the lateral orbital wall (innervated by the zygomatico-temporal nerve) which...

Is exenteration helpful in invasive fungal sinusitis?

Invasive fungal sinusitis is a potentially lethal disease that causes painful orbital apex syndrome with ophthalmoplegia and visual loss. The mechanism of ophthalmoplegia and visual loss is not clear, and neither is the role of radical surgery-orbital exenteration. The authors...

Mast cells in Graves’ ophthalmopathy

Graves’ ophthalmopathy (GO) is a potentially sight-threatening ocular disease, occurring in patients with hyperthyroidism due to Graves’ disease. Also known as thyroid-associated ophthalmopathy, GO is characterised by orbital infiltration by immune cells including macrophages, T cells and plasma cells, which...

Extraocular muscle BT after ocular pathology

Management is described for 13 patients who received inferior rectus botulinum toxin (BT) injection for vertical strabismus due to orbital pathology. Patients were aged 19-86 years, eight were female and seven were right eye injections. Orbital pathology included six with...

Computerised tomography in ocular trauma patients

Ocular trauma can be common in military settings. This retrospective study looked into the relationship between the clinical effects of acute ocular and orbital blast trauma with the findings on computerised tomography (CT). This was a consecutive case series of...

Wide variation in the volume of the sphenoid trigone

This is a radiological study of the volume of the sphenoid trigone in normal subjects. The authors were interested to see how much volume could be gained by removal of the trigone during an orbital decompression for thyroid eye disease....

Computer-assisted surgery in the orbit

In this paper the authors describe the growing use of computer-assisted surgery in ophthalmology. It is already described as a powerful adjunct in neurosurgery and sinus surgery and here they describe their experience of using it for the orbit; specifically...

Globe subluxation subsequent to long-term steroids

Globe subluxation, when the globe equator projects anterior to the orbital rim, is a serious orbital condition commonly associated with thyroid eye disease, floppy eye syndrome or a shallow orbit. The authors present a first case of a spontaneous globe...

PD-1 and PD-L1 in exenteration specimens

This is an immunohistochemical study looking at variation in the expression of the programmed death-1 receptor (PD-1) and the programmed cell death ligand-1 (PD-L1), comparing cutaneous malignancies which invaded the orbit with uncomplicated nodular basal cell carcinomas. The authors retrospectively...

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...

Inverted papilloma

This is a retrospective review of 22 patients with inverted papilloma, including nine cases confined to the nasolacrimal system and 13 involving into the orbit. This is a rare disease and the report is the largest published series of periocular...

Upper eyelid ulceration as a presenting sign of frontal sinus mucocele

Introduction A sinus mucocele is an epithelium-lined sac filled with mucus and desquamated epithelium. It forms secondary to inflammatory processes that occur in a sinus with an obstructed ostium. Predisposing conditions include previous trauma, surgery, tumours, anatomical abnormalities, and chronic...
