Cogan-Reese syndrome is a clinical variant of iridocorneal endothelial (ICE) syndrome (see this term) characterized by variable iris atrophy, pigmented and. This variant of ICE syndrome is distinguised by its Cogan-Reese sub-type of ICE syndrome. A YEAR-OLD woman was first diagnosed as having iridocorneal endothelial syndrome in She underwent a trabeculectomy in Photographs first.

Iridocorneal Endothelial Syndrome and Secondary Glaucoma – EyeWiki
Comparisons may be useful for a differential diagnosis: Scheie HG, Yanoff M. In advanced cogwn penetrating or endothelial keratoplasty may be required, although the failure rate is high with need for repeat corneal grafts.
Scheie HG, Yanoff M. In some individuals, the corneal edema may be improved with reduction in intraocular pressure. Progressive growth of endothelium over iris. Most affected individuals are white. Brisk, reactive to light OS: Prostaglandin analogues may be helpful in some cases. Transmission and Scanning Electron Microscopic examination of these cells has demonstrated a population of well-differentiated cells with epithelial features such as desmosomes, tonofilaments, and microvilli.

Disease definition Cogan-Reese syndrome stndrome a clinical variant of iridocorneal endothelial ICE syndrome see this term characterized by variable iris atrophy, pigmented and pedunculated nodules on the iris and corneal abonormalities.
Affected Populations Cogan-Reese syndrome is a very rare disorder that predominantly affects females in the middle adult years, although cases have been reported in children. Clinical and histopathologic finding of iris nevus Cogan-Reese syndrome.
Cogan-Reese syndrome is unique among the ICE syndromes due to the presence of pedunculated, pigmented iris nodules, syndome referred to as iris nevi . Others suggest that the primary disorder involves the cells that line the cornea corneal endotheliumwith the impact on the iris as a secondary or associated disorder.
Cogan Reese Syndrome – NORD (National Organization for Rare Disorders)
Histologically, these endothelial cells synndrome epithelial features, such as microvilli and desmosomes . Third or greater penetrating keratoplasties: Secondary angle-closure glaucoma is a consequence of high PAS, but can at times occur without overt synechiae because the advancing corneal endothelium can functionally close the angle without contraction.
Additionally, ARS is congenital with patients presenting at a young age, can have systemic findings, and does not have corneal endothelial changes. The patient was pseudophakic OU. Axenfeld-Rieger syndrome is a bilateral, heterogeneous congenital condition that is is autosomal dominant in most cases, but can also occur synvrome, and may include developmental abnormalities in the anterior chamber angle, iris, and trabecular meshwork.
CS is one of three syndromes affecting the eyes progressive iris atrophy and Cogan-Reese syndrome are the ocgan two that make up the iridocorneal endothelial syndrome ICE syndrome. For all other comments, please rewse your remarks via contact us. A Rare Case of Unilateral Glaucoma.
Donald Abrams and Dr. Medical therapy was initiated with oral and topical aqueous suppressants, topical steroid drops, and a cycloplegic agent. Iridocorneal endothelial ICE syndrome is characterized by unilateral abnormal proliferation of the corneal endothelium, corneal edema, and peripheral anterior synechiae PAS.
The definitive mechanism of Cogan-Reese syndrome is unknown.
The optic disc of the left eye had a cup of 0. Both ocular hypertension and corneal decompensation can be addressed with medical and surgical treatment approaches. Syndrkme glaucoma tends to be more severe in progressive iris atrophy and Cogan-Reese syndrome.
Deep and quiet OU Iris: Photographs first taken in demonstrated some ectropian uvea and nodules covering the iris from the 7- to 3: Material for histological study was available from ten patients and showed a nonmalignant diffuse nevus of the anterior surface of the iris.
An overgrowth of endothelium and Descemet membrane extending onto the iris syndrom may be a characteristic part of the process.
Iridocorneal Endothelial Syndrome and Secondary Glaucoma
The decision was made to proceed with surgery given the persistently elevated IOP. Specific findings on anterior syndome OCT that aid in detecting Cogan-Reese syndrome include increased iris thickness . Specular microscopy of the left eye showed pleomorphism and polymegathism with multiple guttatae.
The congenital cataracts, optic nerve and foveal hypoplasia, bilateral presentation, lack of corneal endothelial changes, and congenital nature differentiate aniridia from ICE syndrome.

The iris findings of this variant can be quite robust and progressive over time. Pathology of the iridocorneal-endothelial syndrome. It presents as a unilateral disease, more common in women, between the ages of 20 and sydrome The iris findings are less common, and a majority of patients have no iris changes at all, making the diagnosis a challenge.
The treatment of ICE syndrome, regardless of the variant, primarily revolves around the prevention symdrome glaucomatous vision erese secondary to elevated intraocular pressure. The corneal edema found in ICE syndrome patients is thought to be secondary to both elevated intraocular pressure IOP from secondary angle-closure glaucoma, and from subnormal pump function from the altered corneal endothelial cells.
Additionally, treatment of corneal edema and other corneal changes is vital to maintain high quality visual acuity. Photographs taken in Figure 3 and Figure 4 illustrate a clear progression of the nodules over previously unaffected areas of the iris. Create account Rfese in. Glaucoma drainage devices have shown favorable outcomes in a small number of patients, but further studies are warranted to validate these results in a large series.
