Relevant factors determining the management of inaccessible retained lead airgun pellets are discussed in relation to 11 orbital cases. Although the injuries were of between one month's and 26 years' standing, serum lead levels were normal at under 350 micrograms/l in all instances. This is attributable to the modern alloy composition of the ammunition in(More)
A study of normal locomotion requires an understanding of both the movements and the force actions involved. This is equally true in appreciating the problems of pathological gait. The gait cycle is described in terms of the significant events which occur during both the stance and swing phases. The basic principles underlying the analysis of force actions(More)
Patients with carotid occlusive disease may develop a variety of symptoms and signs secondary to chronic ocular ischaemia. We report six cases affecting nine eyes and review the findings of teichopsia, anterior segment ischaemia, venous stasis retinopathy, and ocular neovascularisation. The assessment and surgical management of carotid obstruction are(More)
A report of 11 cases of solar retinopathy is given. Particular emphasis is laid on the mechanism of light hazard with protective measures available, symptoms including scotomata with visual prognosis, and the clinico-pathological correlation of the findings. These are divided into mild, with early retinal oedema, and moderate, with later development of(More)
Ocular neovascularisation is recognised as an uncommon complication of central retinal artery occlusion (CRAO) but has been associated most frequently in those patients suffering from carotid artery occlusive disease. We report the finding of neovascularisation after CRAO in a group of 8 patients, who have presented over the previous 6 years. Four showed no(More)
Ten patients with disc neovascularisation of various aetiologies were studied to ascertain the origin of their new vessels. Fluorescein angiography was carried out with an image intensified video camera. A retinal artery derivation was demonstrated for the first time and was seen in three cases. Six further patients showed a retinal venous supply, and(More)
