Second primary tumours after sebaceous carcinoma

This is a study investigating the risk of developing a second primary malignancy in patients previously diagnosed with eyelid sebaceous cell carcinoma. The records of 559 patients who were diagnosed with sebaceous cell carcinoma between 2000 and 2016 were reviewed,...

Human leucocyte antigen association of patients with Stevens-Johnson syndrome in Han Chinese

This is a retrospective study of the human leucocyte antigen (HLA) polymorphism pattern of cold medicine-induced patients with Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN) (n=33) and 98 control patients recruited between 2016-2017 in Taiwan. Severe ocular complications (SOC) was...

Ocular findings in children with myasthenia

This is a retrospective audit of paediatric myasthenic patients presenting to Great Ormond Street (GOSH) between January 2016 and January 2020. During this period there were 49 children, including 27 with juvenile myasthenia (JMG) and the rest as congenital myasthenia...

Using a tumour registry to investigate optic nerve gliomas

This study is a retrospective comparative analysis. Patients with optic nerve glioma and pilocytic astrocytoma were identified through the Surveillance, Epidemiology and End Results (SEER) cancer registry covering a 42-year period using standardised codes. The following data was extracted: basic...

ABCA1 mediates lipid efflux in the retina

Age-related macular degeneration (AMD) is the leading cause of blindness in the elderly population. There are two forms of AMD, dry and wet, the latter so named because of the presence of choroidal neovascularisation. Both forms lead to retinal pigment...

A possible biomarker for diabetic retinopathy

Diabetic retinopathy (DR) is the most common form of diabetic eye disease, characterised by exudates, microaneurysms and haemorrhage. Early diagnosis is crucial for preventing visual loss. The risk of developing diabetic retinopathy is known to increase with age as well...

Case report of Leber hereditary optic neuropathy (LHON)

This case report presents a 74-year-old male patient who developed LHON, with a previous diagnosis of bilateral macular holes. LHON occurs predominantly in healthy young men and onset in older age ranges increases the likelihood that the patient will have...

Update on primary angle closure glaucoma

This review article considers primary angle-closure glaucoma which is responsible for half of glaucoma-related blindness worldwide. Angle closure is characterised by appositional contact between the iris and trabecular meshwork. It tends to develop in eyes with shallow anterior chambers, anteriorly...

A case report of visual loss as a consequence of coeliac disease

The authors present a case of permanent visual loss secondary to occipital lobe calcification in coeliac disease, the first reported such case. The 58-year-old man had been diagnosed with coeliac disease 20 years prior to his visual investigations and had...

Ocular characteristics in Marfan syndrome

Marfan syndrome (MFS) is a genetic disorder with clinical manifestations associated with cardiovascular, ocular and skeletal organ systems. Typical signs are descending aortic root aneurysms, ectopia lentis, tall stature and scoliosis. This observational study looked at the ocular characteristics, visual...

HtrA1 enhances cell senescence

A genetic basis for age-related macular degeneration (AMD) has been greatly advanced in recent years. The role of identified pathways such as complement factor H in AMD has been widely investigated. However, the effect of other gene variants identified by...

Caring for adults with an ocular tumour

Detection If you screen for an intraocular tumour, dilate the pupil. If the patient is driving, use phenylephrine only. If the patient declines, document this in the casenotes. Don’t forget to look for sentinel vessels, which would indicate a ciliary...
