Abstract :
ICE syndrome is a rare progressive unilateral disease occurring in
young middle aged females. Corneal edema with uveal involvement are key
features.Secondary glaucoma is main sight threatening
complication.Managment depends on severity of ocular findings and is
targeted to control corneal edema and secondary glaucoma medically and
surgically.
KeyWord: glaucoma, edema with uveal, ICE syndrome.

Introduction:
1. ICE (iridocorneal endothelial)
syndrome is congenital condition, usually unilateral, seen in middle
aged females, not associated with systemic disease [1]. Patient
complains of blurred vision ocular pain.Signs include varying amount of
corneal oedema iris heterochromia and distorted pupil1. ICE syndrome
consists of [3] similar syndromes: Cogan Reese Syndrome-Iris Nevus
,Chandlers syndrome -mild iris thinning, greater corneal edema.,
Essential Iris atrophy-progressive thinning, holes, corectopia [1].
Case report:
We report an 18 year old patient presented to our clinic with blurred
vision and pain persisting for 1 month in the left eye. Patient was
apparently all right 1 month back when she had episode of pain redness
followed by progressive diminution of vision and whitening of cornea.
Family and personal history were not contributory.
No history of trauma or any major systemic illness like tuberculosis,
leprosy.
Stigmata of neurofibromas /Stills disease / other congenital anomalies
were absent.
Examination-
1. Vision in right eye 6/6
2. Left
eyeball was prominent (exophthalmos) and exophoria with moderate
ptosis. Left eye perception of light
with defective projection in superior and nasal quadrant.
3. Slit lamp examination of right eye was normal.
Left eye had following findings:
Unilateral Severe Corneal edema.
Iris Nevus on the anterior surface of iris, from 12 to 4 o
clock position extending up to pupillary margin.
Ectropion uveae.matted appearance of iris stroma, loss of iris crypts
in temporal quadrant.
4. Left eye unilateral secondary glaucoma.IOP 42 mm of Hg schiotz.
5. Fundus and gonioscopy of RE normal and could not be performed on LE
due to severe corneal odema.
6. B scan of RE was normal and LE showed macrophthalmia with axial
length 25 mm.
7. X-ray skull, bilateral knee, USG abdomen, paediatric, cardiology and
orthopaedic examinations were within normal limits.
All these findings were in favor of: -Iris nevus (Cogan-Reese)
syndrome. In our patient medical management was done with local and
systemic anti
glaucoma drugs and intraocular pressure came down to 14.6 mm of Hg in
left eye after 11 days with symptomatic relief.Surgical intervention
for glaucoma and corneal edema was not considered owing to poor visual
prognosis. Our patient is being followed up for secondary glaucoma.

Discussion
Iridocorneal endothelial syndrome is congenital condition , usually
unilateral, seen in middle aged females, not associated with systemic
disease. Patient complains of blurred vision, ocular pain,corneal
edeoma,secondary glaucoma, heterochromia and distorted pupil [1]. ICE syndrome consists of 3 similar syndromes [2].
1. Cogan Reese Syndrome-Iris Nevus
2. Chandlers syndrome -mild iris thinning, greater corneal edema.
3. Essential Iris atrophy-progressive thinning, holes, corectopia.
Etiology is unknown. Epstein Barr virus and Herpes simplex viruses have
been found serologic ally in patients of ICE syndrome [3].These viruses
are suggested to play a role in cell necrosis and in transformation of
endothelial cells. In ICE syndrome the corneal endothelium undergoes an
epithelioid metaplasia that migrates in a membrane form. [2] If it
migrates over the anterior chamber angle, contraction of this membrane
pulls the iris toward the cornea causing a synechial closure of the
angle leading to secondary glaucoma [4].When the abnormal corneal
endothelium spreads on to the iris surface, the contraction causes
atrophy and corectopia.Pigmented iris nodules are also produced by this
contracting abnormal endothelial membrane. Corneal edema occurs due to
the subnormal endothelial pump function.
Cogan -Reese syndrome named after David Glendenning Cogan and Aligernon
Reese, is an extremely rare eye disorder seen in young and middle aged
females, usually affecting one eye, inciduous in onset, characterized
by a matted or smudged appearance of the surface of iris, development
of modular iris nevi, ectropion uveae, peripheral anterior synechiae,
and/or glaucoma. Secondary glaucoma may lead to vision loss. This
disorder most frequently appears in young and middle-agedfemales,
usually affecting one eye (unilateral) and developing slowly over
time.[1] The differential diagnosis of multiple pigmented iris nodules
include-Nuerofibromatosis, melanomas, inflammatory nodules of leprosy,
syphlis, tuberculosis and sarcoidosis. [5]
Chandlers syndrome -This variant shows minimum or no iris atrophy, mild
corectopia may be present. The cornel edema may be more pronounced,
giving pleated silver appearance of posterior corneal surface.
Essential Iris Atrophy-This variant is characterized by severe iris
atrophy resulting in heterochromia, marked corectopia, ectropion uveae,
psuedopolycoria due iris hole formation is hallmark of essential iris
atrophy [3]. Treatment-Main concern of management is secondary glaucoma
which occurs
in about 50% of ICE syndrome patients and is major cause of visual loss
[6].Management options are specific to each case and should be tailored
to degree and severity of secondary glaucoma and corneal edema.
Conclusion
ICE is a rare, progressive, congenital, unilateral disease, of unknown
etiology ,occurring in middle aged females. Main clinical feature is
ocular pain,blurred vision,corneal odema, iris signs include,iris
nodules or nevus or atrophy.Secondary glaucoma is a sight threatening
complication. Management is targeted to reduce corneal edema,and
control secondary glaucoma medically. In severe cases surgical
correction of glaucoma and penetrating keratoplasy is required to
achieve and maintain good vision.
