Vitreous Anomalies Flashcards
Muscae Volitantes
seen against pale background
move with eye
debris in vitreous gel, remnants of embryonic vasculature
Persistent Fetal Vasculature
congenital defect when hyaloid vasculature fails to regress
can extend from post lens to optic disc
Asteroid Hyalosis
accumulation of calcium and phosphate in vitreous
unilateral
rarely affects vision
swirl with eye movement
Synchysis Scintillans
from chronic vitreous hemorrhage or inflammation
cholesterol crystals
often in a blind eye
vitreous liquefied
Amyloidosis
deposition of abnormal protein (amyloid)
can accumulate at posterior lens causing vision issues
Vitreous Hemorrhage
From trauma, retinopathy, bleeding disorders
blurred vision
Treating Muscae Volitantes
vitrectomy
only in serious versions
Bergmeister’s Papilla
glial tissue on optic nerve
asymptommatic
Mittendorf’s Dot
glial remnants on posterior lens surface
asymptommatic
Treating Amyloidosis
pars plana vitrectomy
Clearing Vitreal Hemorrhage
clears at 1% a day- norm gone in 3 months
Monitoring Vitreal Hemorrhage
B scan or ultrasound to watch retinal health
