Condion 21
This view is of the posterior pole centred on the opc disc
The main clinical features are:
• Tortuosity and dilataon of the inferior tem-
poral branch of the central renal vein with
A-V nipping
• Renal haemorrhages: ame shaped, dot
and blot
• Microaneurysms
• Mulple hard exudates
This diagnosis is consistent with:
BRANCH RETINAL VEIN OCCLUSION (BRVO)
Comment:
Hyperviscosity due to any cause has to be excluded. Hypertension alone can cause Branch
Renal Vein Occlusion . The lesions can be understood by considering that arteriolar blood is
going into this temporal arcade but cannot exit through the associated vein.
Condion 22
This view is of the inferior temporal rena
The main clinical features are:
• Boat-shaped pre-renal haemorrhage
• Renal haemorrhages: few dots and blots
• Microaneurysms
This diagnosis is consistent with:
PRE-RETINAL HAEMORRHAGE
Comment:
There are many causes. In this paent, secondary to diabec renopathy, leakage from a
proliferave is likely. Also consider trauma and sub-arachnoid haemorrhage.
