Q

What is this?

A

Wet AMD - scan of a large PED with a large pocket of subretinal luid adjacent to the PED. The RPE is sharp and clear and easy to trace and follow from one side of the scan to the other.

A

Wet AMD - with intraretinal luid/cysts. Note the breakdown of the RPE layer below the luid — it is impossible to trace a line following the RPE across the scan.

Q

What is this?

A

Wet AMD - intraretinal luid (large and small intraretinal cysts) and a small pocket of subretinal luid, indicating that this is wet AMD rather than cystoid macular oedema (CMO).

Q

what is this?

A

Wet AMD - some subretinal luid and subretinal hyperrelective material (SHRM) above the RPE, indicating wet AMD (note this scan is from an Optovue). SHRM tends to be not as relective as denser scars lying above the RPE and, with symptoms, is often a sign of wet AMD.
