This view is of the opc disc and surrounding rena
The main clinical features are:
• Tortuous blood vessels, both veins and ar-
teries, emanang from the opc disc
• There are no other lesions such as haemor-
rhages or hard exudates
• The disc margins are normal
This diagnosis is consistent with:
MEDUSA HEAD OPTIC DISC (This is a normal variant)
Comment:
The tortuous blood vessels are a normal variant. No symptoms are expected. The disc
margins are normal and the striking appearance should not be confused with condions
such as Papilloedema or New Vessels at the Disc or New Vessels Elsewhere.

This view is of the opc disc and surrounding rena
The main clinical features are:
• Marked crescent around the opc disc
• The renal vessels appear to be normal
• The choroidal vessels are visible
This diagnosis is consistent with:
OPTIC DISC CRESCENT IN A PATIENT WITH HIGH MYOPIA
Comment:
Marked crescent around the opc disc due to stretching of the eyeball around the opc
disc. There is oen exposed renal pigment epithelium at this site making the crescent even
more pronounced. The choroidal blood vessels are more pronounced due to thinning of the
renal structures.
