synchisis?
vitreous liquefication
-
syneresis?
exudation of liqued from gel as collagens
-
-
weiss ring
peripapillary glial tissue that remains attached to post vit cortex following detachment
-
vitreoschisis?
spilit in posterior vit cortex
-
PFV?
persistent focal vasculature
-
PHTVL?
persistent hyperplastic tunica vasculosa lentis
-
PHVP
persiste hyperplastic primary vitreous
-
PPM
persistent pupillary membrane
-
PVD
- pockets of water appear within central vitreous and grad coalesce-> weakens vitreoretinal adhesion-> PVD as liquid dissects residual cortical gel away from ILM
- RF for retinal tears and detachment
- bi, myopes
-
floaters?
- cobwebs
- sudden increase-> retinal detachment-> EMERGENCY
- ddx: floaters and/or flashes- PVD, RD, Post uvei
- floaters- vitreous hemorrhage
- flashes- rapid eye movements
-
congenital vitreal opacities?
PHPV- leukocoria ant, post- RD
-
asteroid hyalosis?
- diabetes mellitus
- CA deposits
- M, 60
- moves as vitreous moves
- ddx: amyloidosis, cholestorl bulb
- tx: none
-
synchysis scintillans?
- cholesterol bulb
- free floating cholesterol crystals
-
vitreous amyloidosis
- inherited
- amyloid deposits around collagen fibres
- prog bi/uni
- steel wool/hazy fundus
-
vitreous haemorrhage?
PVD, AMG
-
pre-retinal (subhyaloid) haemorrhage
- anterior to retina, just under ILM
- cant see retinal vessels
-
inflammation/infection
- vitritis- inflammation of celss from choroid/retina/CB
- haze
-
shafer's sign
- RD
- clumping of pigmented cells in ant chamber and on corneal endo- tobacco dust
