Human chorioretinal biopsy under controlled systemic hypotensive anaesthesia. 1980

L J Constable, and G H Chester, and R Horne, and J F Harriott

This paper describes a simplified technique for biopsy of the retina and choroid which had been used in 5 human volunteers. The biopsy was carried out in 4 immediately before enucleation of an eye for malignant melanoma and in 1 patient who was undergoing trabeculectomy for painful glaucoma associated with retinitis pigmentosa. A combination of intravenous mannitol and transient controlled systemic hypotension, induced under general anaesthesia with intravenous sodium nitroprusside, was used in 3 cases and resulted in no vitreous loss and minimal bleeding. In the 2 cases in which hypotension was not used bleeding was a definite problem, but no vitreous loss was experienced.

UI MeSH Term Description Entries
D007023 Hypotension, Controlled Procedure in which arterial blood pressure is intentionally reduced in order to control blood loss during surgery. This procedure is performed either pharmacologically or by pre-surgical removal of blood. Controlled Hypotension,Hypotension, Induced,Induced Hypotension
D008297 Male Males
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D012160 Retina The ten-layered nervous tissue membrane of the eye. It is continuous with the OPTIC NERVE and receives images of external objects and transmits visual impulses to the brain. Its outer surface is in contact with the CHOROID and the inner surface with the VITREOUS BODY. The outer-most layer is pigmented, whereas the inner nine layers are transparent. Ora Serrata
D002829 Choroid The thin, highly vascular membrane covering most of the posterior of the eye between the RETINA and SCLERA. Choriocapillaris,Haller Layer,Haller's Layer,Sattler Layer,Sattler's Layer,Choroids
D005260 Female Females
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
