colour sp. A two- or three-dimensional representation of colour stimuli. Example: CIE chromaticity diagram.
gaussian space See paraxial region.
horopter space The horopter consisting of all object points in space which stimulate corresponding retinal points as distinguished from the two-dimensional cases such as the apparent frontoparallel plane, longitudinal or nonius horopters.
image space Region on one side of an optical system in which the image is formed. See object space.
intertrabecular space See trabecular meshwork.

Panum's fusional space An area in space corresponding to Panum's area within which there is fusion and stereopsis of a non-fixated target. See Panum's area; horopter.
perichoroidal space See suprachoroidal space.
suprachoroidal space A potential space located between the choroid and the sclera. Anteriorly it is continuous with the supraciliary space. It contains thin, pigmented strands of collagen fibres and it is traversed by the long and short posterior ciliary arteries and nerves. Syn. perichoroidal space.
supraciliary space A potential space located between the ciliary body and the sclera. In this space are thin strands of collagen fibres derived partly from the suprachoroid and partly from layers of the ciliary muscle. This space together with the suprachoroidal space form part of the unconventional route of aqueous humour outflow, the uveoscleral pathway. See uveoscleral pathway.
