ICE syndrome (iridocorneal endothelial syndrome)
20~50歲,女性較多,雙側為主
Secondary angle-closure glaucoma
分類
Iris nevus syndrome (Cogan Reese syndrome)
最少Iris atrophy
表面有很多pedunculated nodules或diffuse pigmentaed lesion
Chandler syndrome (佔50%以上,最多)
有iris atrophy,可能沒有IOP升高就發生corneal edema
有microcystic edema, endothelial dysfunction,造成mild IOP↑
Essential iris atrophy (EIA)
Iris atrophy程度最嚴重!
眼壓升高:
ICE當中,50%會發生glaucoma
I、E較嚴重,C較不嚴重 ( EIA及Cogan-Reese較容易有嚴重glaucoma)
可能會因為retractable glaucoma而最終需要PKP
Iris atrophy: E > C > I
Cornea endothelium
呈現”beaton bronze”, 或hammerd silver appearance,很像Fuchs endothelial dystrophy。
嚴重都可產生bullous keratopathy
microcystic edema, endothelial dysfunction, IOP↑
High PAS,會超過Schwalbe’s line (上右圖為ICE syndrome之gonio)
一般的PAS, NV無法越過healthy cornea,理應終止於Schwalbe’s line
只有ICE因角膜內皮異常而讓PAS越過Schwalbe’s line (最後防線)
治療:
用aqueous supressant
miotics無效!手術有效!

The ICE syndrome is nearly always clinically unilateral, although subclinical abnormalities of the corneal endothelium in the fellow eye are common.
what is Chandler syndrome?
