Occult, type 2 no PED wet ARMD
In this type of ARMD, there are new blood vessels, but they are not clearly seen with the angiogram. 'Occult' CNV is the term given to a specific 'blotchy' appearance of the angiogram. Occult ARMD is probably an early phase of classic, see . Occult and classic patterns can occur together. Anti-VEGF drugs generally help. The symptoms of this type of CNV are the same as 'classic CNV', except the condition takes longer to develop. Without treatment, this type 2 occult CNV usually turns into classic CNV over the next months or years, to cause poor central vision.
