Flashcards in 5 - Opth - Acute loss of vision - Posterior vitreous detachment (PVD) + Retinal detachment Deck (7):
1

PVD - 3 features

usually benign, leads to increased number of floaters, degenerative changes in vitreous (liquefaction) leads to detachment from posterior retina

2

In what conditions does PVD occur earlier

myopia, trauma, inflammation, conn tiss disease

3

Complications of PVD

vitreous haemorrhage, retinal tear, retinal detachment

4

Management of PVD

reassurance and advice if uncomplicated

seek help if flashes occur, decreased VA, or curtain field defect

5

Retinal detachment - what happens? other causes?
more common in? where is detachment most rapid?

more common in myopes

detachment of vitreous may lead to retinal tear then detachment (fluid enters between retina and RPE) - can also be caused by surgery/trauma (cataracts)

detachment most rapid in superior retina due to gravity

6

Presentation of retinal detachment

4F's
Floaters, flashes, field loss (curtain), fall in acuity (if macula detached)

abnormal red reflex
grey ballooning retina

7

management of retinal detachment

treat larger retinal tears with laser photocoagulation

surgical intervention fro detachment
