| CRV | central retinal vein |
| CRVO | central retinal vein occlusion |
| retinal vein | <ophthalmology> Central retinal vein and its tributaries. It runs a short course within the optic nerve and then leaves and empties into the superior ophthalmic vein or cavernous sinus. (12 Dec 1998) |
|---|---|
| retinal vein occlusion | <ophthalmology> Occlusion of the retinal vein. Those at high risk for this condition include patients with hypertension, diabetes mellitus, arteriosclerosis, and other cardiovascular diseases. (12 Dec 1998) |
| retinal vessels | <ophthalmology> The vessels which supply and drain the retina. (12 Dec 1998) |
| rhegmatogenous retinal detachment | Retinal separation associated with a break, a hole, or a tear in the sensory retina. (05 Mar 2000) |
| pigmented retinal epithelium | Layer of unusual phagocytic epithelial cells lying below the photoreceptors of the vertebrate eye. The dorsal surface of the PRE cell is closely apposed to the ends of the rods and as discs are shed from the rod outer segment they are internalised and digested by the PRE. Do not have desmosomes or cytokeratins in some species. (18 Nov 1997) |
| trans-retinal | The orange retinaldehyde resulting from the action of light on the rhodopsin of the retina, which converts the 11-cis-retinal component of the rhodopsin to all-trans-retinal plus opsin. Synonym: trans-retinal, visual yellow. (05 Mar 2000) |
| exudative retinal detachment | Detachment of the retina without retinal breaks, arising from inflammatory disease of choroid, retinal tumours, and retinal angiomatosis. (05 Mar 2000) |
| falciform retinal fold | A congenital fold from the disk to the ciliary region in the inferior temporal quadrant of the retina. (05 Mar 2000) |
| unequal retinal image | A condition in which the ocular image of an object as seen by one eye differs in size and shape from that seen by the other. (12 Dec 1998) |
| 11-cis-retinal | The isomer of retinaldehyde that can combine with opsin to form rhodopsin; it is formed from 11-trans-retinal by retinal isomerase. Synonym: neoretinal b. (05 Mar 2000) |
| anterior medial malleolar artery | <anatomy, artery> Origin, anterior tibial; distribution, ankle joint and neighboring integument; anastomoses, branches of posterior tibial. Synonym: arteria malleolaris anterior medialis. (05 Mar 2000) |
| bilateral medial orbital ecchymoses | <clinical sign, ophthalmology> The appearance of the eyes produced by subconjunctival haemorrhage and/or periorbital ecchymosis. Synonym: bilateral medial orbital ecchymoses. (21 Jun 2000) |
| calcarine branch of medial occipital artery | <anatomy, artery> Branch of medial occipital artery which runs in relationship to the calcarine sulcus. Synonym: ramus calcarinus arteriae occipitalis medialis, arteria calcarina, calcarine artery. (05 Mar 2000) |
| parietal branch of medial occipital artery | <anatomy, artery> An anterior branch of the medial occipital artery supplying the posterior section of the parietal lobe of the cerebrum. Synonym: ramus parietalis arteriae occipitalis medialis. (05 Mar 2000) |
| medial | The side of the body or bdy part that is nearer to the middle or centre (median) of the body. For example, when referring to the knee, medial would mean the side of the knee that is closest to the other knee the opposite of medial is lateral. (12 Dec 1998) |
