- Pterygium is a common ocular surface disorder characterized by chronic proliferative conjunctival fibrovascular tissue growth over the cornea.1 Numerous pterygium excision techniques have been tried with a wide range of recurrence rates, including bare sclera excision (30%–70%),2 amniotic membrane (6.4%–42.3%), and conjunctival autograft with or without glue (0%−16.7%).3,4 A recent Cochrane study found a 47% reduced risk of recurrence with conjunctival autograft at 6 months compared with amniotic membrane for pterygium excision.
- The retinal astrocytic hamartoma is a hallmark ophthalmic feature of tuberous sclerosis complex (TSC).1 The typical course of such tumours is a relatively slow-growing nonaggressive lesion in the retina that can be managed expectantly.2 Nonetheless, there have been several reports in the literature of aggressive astrocytic hamartomas that do not demonstrate this benign course.3 We present here a rare case of an aggressive tumour in a patient with TSC that has cell types more typical of the subependymal giant cell astrocytoma (SEGA) that is seen in the brains of such patients.
- Giant cell arteritis (GCA) is a potentially fatal medium- to large-vessel vasculitis with ocular and systemic involvement. The most common ocular manifestation is anterior arteritic ischemic optic neuropathy (AAION), which can be blinding and may affect 1 or both eyes. Systemically, aortitis is the most serious potential complication of GCA, as it can lead to aortic dissection and aortic aneurysms.1
