1) Iris melanoma, the most common malignancy of the iris, originates from the melanocytes of the iris stroma
and its prognosis is better than that of choroid and ciliary body melanomas.
When we are born, all the data related to the tissues of the organism, the nervous system, the mechanical and psychological brain, the organs, and the lymphatic system are already imprinted in the iris stroma
just like a map or cartography.
Likewise, the iris stroma
may be grossly abnormal including generalized atrophy with correctopia, ectropion uveae, and often is similar in clinical appearance to iridocorneal endothelial syndrome (ICE).
7) Heterochromia is caused by gradual atrophy of the iris stroma
in the affected eye.
Iris melanomas arise in the iris stroma
, have a predilection for white persons, and are usually located in the inferior portion of the iris.
Based on information revealed in taking the medical history and clinical findings, he was further referred to an ophthalmologist who reported hypoplasia of the iris stroma
and an asymmetric pupil, thereby confirming the tentative diagnosis of Rieger syndrome.
18) The aim is to separate the abnormal extensions of iris stroma
from the angle wall, thus preventing closure of the angle.
With clinical suspicion of epithelial downgrowth, argon laser photocoagulation was performed over anterior iris stroma
to confirm diagnosis, but no bleaching was achieved in any of multiple shots targeting different parts of the iris.
In Stage 2 NVI, the new vessels have 'pierced' the anterior iris surface near the pupil and the root of the iris; the two sets of blood vessels will extend and merge, and more new vessels will form in the iris stroma
Primary cyst can arise from iris pigmented epithelium / iris stroma
The ophthalmological examination revealed amelanotic, yellow-white nodular mass in the iris stroma
in his right eye.
Iris mammillations, which are tiny, numerous, villiform, brown nodules occupying the iris stroma
, are also common.
