Condion 13
This view is of the opc disc and temporal rena
The main clinical features are:
• Focal areas of atrophy of renal pigment in
the central macular area
(fovea centralis)
• Drusen in the macular area
This diagnosis is consistent with:
DRY AGE-RELATED MACULAR DEGENERATION
Comment:
Presence of haemorrhages and oedema in the macular area would suggest wet changes (not
seen here).
Condion 14
This view is of the opc disc and temporal rena
The main clinical features are:
• Focal narrowing of arterioles
• Changes at arterio-venous crossings along
inferotemporal arcade (A-V nipping
This diagnosis is consistent with:
HYPERTENSIVE RETINOPATHY: GRADE 2
Comment:
Absence of haemorrhages (ame shaped) and disc swelling suggest early changes or chronic
hypertension. The grading system can be summarised as follows:
Microaneurysms (MA) are rare in hypertensive renopathy without diabetes mellitus
Grade 1: Arteriolar narrowing
Grade 2: Arterio-venous nipping
Grade 3: Exudates, Haemorrhages, Coon wools spots (CWS)
Grade 4: Papilloedema
