PURPOSE Autosomal dominant optic atrophy (DOA) is a major cause of visual impairment in young adults that is characterized by selective retinal ganglion cell loss. To define the prevalence and natural history of this optic nerve disorder, we performed a population-based epidemiologic and molecular study of presumed DOA cases in the north of England. (More)
Central sensory and motor fusion of images, once established, is usually maintained throughout life. Under certain circumstances, this ability may be lost. This gives rise to the syndrome known as horror fusionis, or acquired disruption of central fusion. We report the development of central fusion disruption in three patients with uniocular mature senile(More)

Purpose: To assess the level of awareness among UK ophthalmic surgeons of the potential risks from starch powdered surgical gloves during ophthalmic surgery and to show by electron microscopy that starch granule contamination can occur during ophthalmic surgery. Setting: A sample (N = 46) of UK ophthalmologists from the North of England, UK. Methods: Type(More)
