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?
