Abstract
PRCIS Our study highlights the long-term success of trabeculectomy or Ahmed glaucoma valve (AGV) surgery in patients with glaucoma secondary to iridocorneal endothelial (ICE) syndrome. However, many ICE syndrome cases may need multiple glaucoma surgeries to achieve controlled intraocular pressure (IOP), with/without concomitant corneal graft surgery. OBJECTIVE To evaluate the long-term outcome of trabeculectomy and AGV implantation in ICE syndrome. METHODS Patients with glaucoma secondary to ICE syndrome who underwent either trabeculectomy or AGV surgery with intraoperative adjunctive mitomycin-C from 2009 to 2020 were included in this study. All patients were followed for at least 6 months after initial surgery. The main outcome measures were IOP, number of IOP-lowering medications, and surgical success. Surgical success was defined as complete according to the levels of IOP ( < 18) and at least 20% reduction from preoperative IOP without medications and qualified as a complete success but with medications, where the number of medications was less than preoperative numbers. Cumulative success was the sum of the qualified and complete success. RESULTS Twenty-nine eyes of 29 patients were included. Trabeculectomy was done in 13 patients (group A, 44.8%) and 16 patients underwent AGV surgery (group B, 55.2%). The median age was 50 (42-56.50) and 47 (36.75-52.75) years in groups A and B, respectively ( P = 0.10). All patients completed at least 2 years of follow-up. Mean IOP was not significantly different between groups preoperatively ( P = 0.70) and the effect of the type of surgery on IOP was not statistically significant at multiple follow-up time points (repeated measures analysis of variance, P = 0.44). The mean IOP decreased from 35.76 ± 6.36 mm Hg preoperatively to 16.00 ± 3.10 in group A and from 36.12 ± 8.11 mm Hg to 17.00 ± 3.75 in group B ( P = 0.449) at year 2 of follow-up. The effect of the type of surgery was not significant on the total number of IOP-lowering medications used throughout the study (repeated measures analysis of variance, P = 0.81). Kaplan-Meier analysis shows complete success in 14 patients (48.3%), 11 patients (37.9%), and 7 patients (24.1%) at 6-month, 1-year, and 2-year follow-up, respectively. The cumulative success rate was 95% at 2 years follow-up for all patients. CONCLUSIONS In 2-year follow-up, trabeculectomy or AGV significantly reduced the IOP in glaucoma patients secondary to ICE syndrome.

Abstract
Purpose Iridocorneal endothelial (ICE) syndrome may cause refractory glaucoma due to progressive synechial closure or membrane formation at the anterior chamber angle. Filtration surgeries are often required but are associated with a higher rate of surgical failure or complications than other types of glaucoma. Herein, we report a new and effective surgical procedure for glaucoma secondary to ICE syndrome: Ex-PRESS shunt combined with ab-interno peripheral iridectomy using a small-gauge vitreous cutter. Methods Three patients with ICE syndrome who underwent surgery were included. Intraoperatively, an ab-interno peripheral iridectomy was performed using a small-gauge vitreous cutter through a corneal incision in the superior-nasal or superior-temporal quadrants to create space for the insertion of Ex-PRESS shunt free from the iris tissue. The shunt was inserted under the scleral flap. The first patient underwent combined cataract surgery, whereas patients 2 (pseudophakia) and 3 (phakia) underwent Ex-PRESS alone. Results No intraoperative complications were observed. The intraocular pressure remained stable until the final postoperative visits at approximately 7, 4, and 1 year in Cases 1, 2, and 3, respectively. Case 2, with mild preoperative corneal edema due to graft failure in Descemet's stripping automated endothelial keratoplasty (DSAEK), underwent reDSAEK 6 months postoperatively. Conclusions and importance Ex-PRESS shunt combined with ab-interno peripheral iridectomy using a small-gauge vitreous cutter may be a safe and effective surgical procedure in patients with ICE syndrome, regardless of the lens status.

Abstract
PURPOSE To compare the surgical outcomes of the Aurolab aqueous drainage implant (AADI) and trabeculectomy with mitomycin C (MMC) in patients with glaucoma secondary to iridocorneal endothelial (ICE) syndrome. MATERIALS AND METHODS This retrospective comparative case series included 41 eyes of 41 patients with ICE syndrome and glaucoma who underwent either a trabeculectomy with MMC (n = 20) or AADI surgery (n = 21) with a minimum of 2 years follow-up. Outcome measures included intraocular pressure (IOP), the use of glaucoma medications, visual acuity, additional surgical interventions, and surgical complications. Surgical failure was defined as IOP > 21 mmHg or reduced < 20% from baseline, IOP ≤ 5 mmHg, reoperation for glaucoma or a complication, or loss of light perception vision. RESULTS The cumulative probability of failure at 2 years was 50% in the trabeculectomy group (95%CI = 31-83%) and 24% in the AADI group (95%CI = 11-48%) (p = 0.09). The IOP was consistently lower in the AADI group compared with the trabeculectomy group at 6 months and thereafter. Surgical complications occurred in 13 eyes (65%) in the trabeculectomy group and 12 eyes (57%) in the AADI group (p = 0.71). Reoperations for glaucoma or complications were performed in 12 eyes (60%) in the trabeculectomy group and 5 patients (24%) in the tube group (p = 0.06). Cox proportional hazards showed that AADI had a 53% lower risk of failure at 2 years (p = 0.18; HR = 0.47; 95%CI = 0.16-1.40). CONCLUSION AADI surgery achieved lower mean IOPs than trabeculectomy with MMC in managing glaucoma secondary to ICE syndrome. A trend toward lower rates of surgical failure and reoperations for glaucoma and complications was observed following AADI placement compared with trabeculectomy with MMC in eyes with ICE syndrome.

Abstract
PURPOSES To report the efficacy of a bleb-independent penetrating canaloplasty in the management of glaucoma secondary to iridocorneal endothelial syndrome (GS-ICE). DESIGN Prospective, non-comparative clinical study. METHODS Penetrating canaloplasty was performed on 35 eyes from 35 patients with GS-ICE and medically uncontrolled IOP between January 2018 and April 2020. Patients were followed up at one week, month 1, 3, 6, 12 postoperatively, and semi-annually thereafter. Intraocular pressure (IOP), number of anti-glaucoma medication and surgery-related complications were recorded. Surgical success was defined as IOP ≥5 and ≤21mmHg without (complete success) or with/without (qualified success) IOP-lowering medications. RESULTS A total of 29 eyes (82.9%) had 360° catheterization and successfully received penetrating canaloplasty. Of these eyes, 24 (82.8%) achieved qualified success and 22 (75.9%) achieved qualified success at 12 months after surgery. The mean IOP decreased from 39.5±11.8 mmHg on 2.9±1.0 medications before surgery to 16.6±5.3 mmHg (P<0.001) on 0.2±0.6 medications (P<0.001) at 12 months post-operation, respectively. Hyphema (37.9%), transient hypotony (34.5%) and transient post-operative IOP elevation (≥30mmHg, 17.9%) were the most commonly observed early complications at the one week and one month visits. From one month and beyond, all treated eyes showed no obvious bleb at the operation quadrant. CONCLUSIONS Penetrating canaloplasty rescued the inner aqueous outflow in ICE eyes and demonstrated quite acceptable success in IOP control with few complications, providing a new option for the management of GS-ICE.

Abstract
PURPOSE Iridocorneal endothelial (ICE) syndrome is well known to cause refractory glaucoma in young adults. Commonly acclaimed mechanism for trabeculectomy failure in these cases include accelerated subconjunctival fibrosis, abnormal endothelial proliferation, and closure of ostium. In the following article, we present a case of Iridocorneal endothelial syndrome that presented with refractory glaucoma after trabeculectomy due to rapidly progressive peripheral anterior synechiae causing angle closure and corneal decompensation that mandated a tailored surgical approach of management. Methods: This is a descriptive case report based on electronic medical records, patient observation, surgical intervention, and follow-ups. Case description: A thirty-eight-year-old-male presented to us with signs suggestive of iridocorneal endothelial syndrome with gonioscopy revealing peripheral anterior synechiae (PAS) over four clock-hours temporally. Uncontrolled intraocular pressure (IOP) despite maximal medical therapy mandated augmented trabeculectomy with anti-fibrotics. The bleb failed within 3 weeks of trabeculectomy, with evidence of progressive crawling PAS causing endothelial decompensation and raised IOP. He underwent Ahmed glaucoma valve (AGV) implant surgery with viscosynechiolysis and sectoral iridectomy under antiviral cover. This helped control IOP and retain corneal clarity, with no recurrence of PAS in the affected area. Conclusion: Progressive peripheral synechiae in ICE syndrome can cause early bleb failure and refractory glaucoma. Careful viscosynechiolysis and sectoral iridectomy alongside a second implant surgery can help salvage visual functions and preserve corneal clarity while preventing further progression of PAS in these eyes.

Abstract
PRéCIS:: This case series reports safe, effective implantation of XEN gel stents to treat iridocorneal endothelial (ICE) syndrome. The stents continue to function well and have not been occluded by membranes or peripheral anterior synechiae, but continued follow-up is necessary. PURPOSE ICE syndrome-related glaucoma is often refractory to medical treatment, and traditional surgical treatment has lower success rates than typical for other types of glaucoma. We present a series of patients who were treated with XEN gel stent implantation. PATIENTS AND METHODS Retrospective case series of 4 patients with ICE syndrome who underwent XEN with subconjunctival mitomycin C injection. RESULTS Average preoperative intraocular pressure was 28.5 mm Hg on 3.8 glaucoma medications, and average postoperative intraocular pressure was 10.5 mm Hg on 1.0 medication. No patients required return to the operating room for additional procedures over an average of 6.9 months of follow-up. One patient had shallow anterior chamber that resolved with conservative management. Another had shallow anterior chamber that resolved with anterior chamber reformation with viscoelastic and developed nonappositional choroidal effusions that had resolved at most recent follow-up of 7 months after surgery. No XEN implants have been occluded by membrane formation or peripheral anterior synechiae. CONCLUSIONS XEN is a safe and effective option for surgical management of ICE syndrome-related glaucoma. Further follow-up surveillance is necessary.

Abstract
OBJECTIVES To evaluate the long-term outcome of patients with iridocorneal endothelial (ICE) syndrome who underwent Ahmed glaucoma valve implantation surgery for uncontrolled glaucoma. METHODS Eighteen patients who suffered from unilateral ICE syndrome with uncontrolled glaucoma and subsequently underwent Ahmed aqueous shunt surgery at Zhongshan Ophthalmic Center between January 2008 and December 2016 were reviewed. Outcome measures included intraocular pressure (IOP), the use of glaucoma medications, visual acuity, further surgical interventions, and surgical complications. RESULTS The mean IOP was reduced from 34.8 ± 10.6 mmHg on 3.6 ± 0.5 medications to 17.4 ± 4.9 mmHg (t = 6.791, P = 0.000) on 1.6 ± 1.1 medications (Z = -3.545, P = 0.000) at the last follow-up (42.0 ± 19.3 months). Five eyes (27.8%) achieved complete success, nine (50.0%) achieved qualified success, and the remaining four (22.2%) were considered failures. Survival was 94.4% at 1 year, 88.1% at 2 years, and 73.5% at 3 years. Four cases displayed a flat anterior chamber and were treated with a single anterior chamber reformation surgery with no recurrence. No other complications related to the glaucoma drainage implants occurred in this series. CONCLUSIONS Ahmed glaucoma valve implantation appears to be a safe and effective method for treating glaucoma secondary to ICE syndrome. Postoperative shallow anterior chamber and hypotony may occur but responds well to the treatment. Early consideration may be given to aqueous shunt surgery in patients with glaucoma secondary to ICE syndrome when trabeculectomy fails.

Abstract
Background To describe a case of a rare association of bilateral keratoconus and unilateral essential iris atrophy and to conduct a literature review of the current strategies of treatment of the corneal disease and glaucoma in patients with Iridocorneal Endothelial Syndrome (ICE). Case presentation We report a rare association of bilateral keratoconus and unilateral essential iris atrophy in a 38-year-old man. Diagnosis of bilateral keratoconus was confirmed by corneal topography. Slit-lamp examination showed extensive iris atrophy with corectopia and policoria in one eye. Corneal specular microscopy revealed an abnormal endothelium morphology in the same eye with extensive peripheral anterior synechiae and closure of the drainage angle at gonioscopy. Intraocular pressure was 26 mmHg, despite maximal topical therapy. Optic disc examination showed severe glaucomatous cupping. Surgery by glaucoma drainage device implantation was performed. Conclusion Essential iris atrophy is a rare clinical variant of ICE syndrome characterized by profound anatomical alterations of the anterior segment associated with corneal edema and secondary glaucoma. In these patients, selective keratoplasties have replaced penetrating keratoplasty to treat corneal decompensation and glaucoma drainage devices are preferred to conventional trabeculectomy for the treatment of secondary glaucoma.

Abstract
Introduction: The failure rate of both filtration surgery and of aqueous shunt implantation is higher for iridocorneal endothelial syndrome than in other scenarios, due to the continuous proliferation of abnormal endothelial cells over the trabecular meshwork and the filtration area and also due to the more pronounced cicatrizing response shown by these young patients. We present the first case ever described in the literature of a pregnant patient with iridocorneal endothelial syndrome and uncontrolled ocular hypertension who was implanted an Ex-PRESS mini-shunt. Clinical case: A 35-year-old female presented with diminution of vision in the left eye for 2 months. She was 20 weeks pregnant. Her visual acuity was 20/20 in right eye and 20/25 in left eye, and intraocular pressure was 11 mmHg in right eye and 34 mmHg in left eye. Slit lamp biomicroscopic examination revealed no alterations in right eye, whereas left eye showed corectopia and uveal ectropion, stroma of iris’ sectoral atrophy and moderate corneal epithelial edema. Gonioscopy showed some anterior iris synechiae in left eye. Fundus evaluation was normal. Based on clinical features and examination, the diagnosis of left eye iridocorneal endothelial syndrome with decompensated intraocular pressure was made. She was prescribed topical timolol (0.5%) and dorzolamide. As a result of uncontrolled intraocular pressure and the impossibility to prescribe other hypotensive treatment available due to her being pregnant, it was decided to perform surgery in left eye using an Ex-PRESS mini-shunt and Ologen®; 6 months post surgery, intraocular pressure was 9 mmHg with no need for hypotensive treatment. The cornea was transparent, and the patient maintained her left eye visual acuity. Conclusions: Ex-PRESS mini-shunt can be considered a surgical option for iridocorneal endothelial syndrome. Its composition allows the ostium to remain open and the device triggers a milder postoperative inflammatory response. In our particular case, taking into account that the subject was a young, phakic, pregnant woman, whose intraocular pressure had to be closely controlled and we had to ensure that her postoperative care included as few drugs and as few reoperations as possible, we thought that using this device was the most appropriate option.

Abstract
This article aims to review the clinical management strategies available for the rare iridocorneal endothelial syndrome. The different clinical variations as well as the imaging techniques available to aid diagnosis are discussed. We then present the evidence available to help the reader to understand how the condition can be managed medically and also the important surgical aspects of treatment. This involves raised intraocular pressure management in addition to the visual management options of partial or full thickness keratoplasty. We hope that this review provides an exhaustive but also succinct review of the literature available on what is a rare and difficult condition to treat.

Etiological mechanism of iridocorneal endothelial (ICE) syndrome may involve infection of herpes simplex virus (HSV) and integration of viral genes into human genome. Med Hypotheses 2018; 110:50-52.

Abstract
Iridocorneal (ICE) syndrome is a rare ocular disease characterized by abnormal proliferation of corneal endothelial cells, progressive obstruction of irido-corneal angle and atrophy of iris. ICE syndrome progressed slowly, but can cause serious complications such as secondary glaucoma in late stage. Because the etiology of ICE syndrome is not clear, there is still no effective treatment in clinical practice. Previous studies have detected herpes simplex virus (HSV) DNA inside patient's aqueous humor. However, no further explanation for HSV-related etiology of ICE syndrome was established. Besides, construction of animal models using HSV all failed, leaving behind a blank space about how HSV infection finally led to ICE syndrome. By summarizing findings from previous studies, we came up with a hypothesis about etiology of ICE syndrome: HSV infection initiated ICE syndrome by integration of viral genetic material into human genome. Infection of HSV changed activity and morphology of endothelial cells, making them regain the ability of mitosis. Proof of such hypothesis will provide a theoretical foundation for construction of animal models and effective intervention of the disease.

Abstract
PURPOSE Iridocorneal endothelial (ICE) syndrome is a rare condition, and unique characteristics in Chinese patients can make diagnosis difficult. Our purpose was to describe the clinical characteristics and variations of ICE syndrome in 58 consecutive Chinese patients. METHODS The clinical data of consecutive patients with ICE syndrome who were seen between 2008 and 2011 at the glaucoma clinic of our ophthalmology department were retrospectively reviewed. The diagnostic criteria for ICE syndrome were a "hammered-silver" appearance of the corneal endothelium and specular microscopy showing ICE cells characterized by the absence of a hexagonal appearance, dark areas within the cells, and a light-dark reversal pattern. The general characteristics of the cornea, iris, pupil, and anterior chamber angles were compiled and examined. RESULTS Fifty-eight patients with ICE syndrome were identified: 26 had Chandler's syndrome (CS), 23 Cogan-Reese syndrome, and nine progressive iris atrophy (PIA). The incidence of glaucoma was 98%. Twenty-three (39.7%) patients had atypical ICE syndrome. Intraocular pressure was relatively high in 13 patients with slightly damaged irises, while the corneal endothelium remained relatively intact. Slit lamp examination showed an intact iris in ten patients (17.2%), with massive deposition of black pigment in the anterior chamber angle. In the 25 patients in whom the anterior chamber angle was only partially closed, 80% of the anterior chamber angles were hyperpigmented. CONCLUSIONS CS is the most common variation of ICE syndrome in Chinese patients, and PIA is the least common. A slight change or an intact iris under slit lamp examination is a characteristic of ICE syndrome.

Abstract
The iridocorneal endothelial (ICE) syndrome is a rare ocular disorder that includes a group of conditions characterized by structural and proliferative abnormalities of the corneal endothelium, the anterior chamber angle, and the iris. Common clinical features include corneal edema, secondary glaucoma, iris atrophy, and pupillary anomalies, ranging from distortion to polycoria. The main subtypes of this syndrome are the progressive iris atrophy, the Cogan-Reese syndrome, and the Chandler syndrome. ICE syndrome is usually diagnosed in women in the adult age. Clinical history and complete eye examination including tonometry and gonioscopy are necessary to reach a diagnosis. Imaging techniques, such as in vivo confocal microscopy and ultrasound biomicroscopy, are used to confirm the diagnosis by revealing the presence of “ICE-cells” on the corneal endothelium and the structural changes of the anterior chamber angle. An early diagnosis is helpful to better manage the most challenging complications such as secondary glaucoma and corneal edema. Treatment of ICE-related glaucoma often requires glaucoma filtering surgery with antifibrotic agents and the use of glaucoma drainage implants should be considered early in the management of these patients. Visual impairment and pain associated with corneal edema can be successfully managed with endothelial keratoplasty.

Abstract
PURPOSE To describe and compare graft survival and intraocular pressure (IOP) control after penetrating keratoplasty (PK) and Descemet stripping automated endothelial keratoplasty (DSAEK) in eyes with iridocorneal endothelial (ICE) syndrome. DESIGN Retrospective case series. METHODS Multicenter study conducted at the Singapore National Eye Centre (SNEC) and Price Vision Group. Twenty-nine consecutive eyes with ICE syndrome that underwent keratoplasty between 1991 and 2011 were identified from the SNEC transplant database and Price Vision Group patient database and the following data extracted: demographics, graft failure, IOP indices, and glaucoma treatment pre- and postkeratoplasty. The main outcome measures were graft failure and need for additional IOP-lowering treatment after keratoplasty. RESULTS The mean follow-up duration was 7.0 ± 4.9 years in the PK group (n = 17) and 4.0 ± 2.6 years in the DSAEK group (n = 12). After a mean of 4.1 ± 3.1 years, 37.9% of grafts (11/29) failed: 7 PK compared to 4 DSAEK (P = .72). The graft failure rate was 50% in eyes with prekeratoplasty glaucoma surgery vs 31.6% in those without (P = .43). Additional glaucoma treatment was required in 37.9% of eyes (11/29): 41.2% of PK eyes and 50% of DSAEK eyes (P = .28) Eyes that had undergone glaucoma surgery before keratoplasty were less likely to require escalation of IOP-lowering therapy postkeratoplasty (9.1% vs 50%, P = .03). CONCLUSIONS One-third of grafts failed after keratoplasty for ICE syndrome at a mean duration of 4 years and additional IOP-lowering treatment was required in 37.9%. Both PK and DSAEK had similar outcomes with regard to graft failure and IOP control.

Abstract
Secondary angle closure glaucomas are a distinct entity from primary angle closure glaucoma (PACG). Unlike PACG, secondary angle closure glaucoma's have an identifable contributory factor/s for angle closure and obstruction of aqueous fow which is usually unrelieved by iridotomy. The treatment of each type of secondary angle closure glaucoma is varied, so identification of the primary cause aids in its effective management. How to cite this article: Annadurai P, Vijaya L.

Abstract
Iridocorneal endothelial (ICE) syndrome is a primary endothelial abnormality that can cause a spectrum of iris changes, corneal edema, and glaucoma. Glaucoma secondary to ICE is difficult to manage because of the inflammatory reaction and fibrosis it can cause. We present a case of postoperative fibrinous reaction following endoscopic cyclophotocoagulation in ICE that caused aqueous tube shunt occlusion and high intraocular pressure. The condition was successfully managed with tissue plasminogen activator.

Abstract
BACKGROUND There are many conditions affecting the corneal endothelium with similar clinical appearances, though with different prognoses, management approaches, and pathophysiologic development. CASE A 39-year-old black woman with a previous diagnosis of asymmetric corneal posterior polymorphous dystrophy (PPMD) presented complaining of irritation in the left eye, worsening over the last week. On examination, her left eye had profuse edema and bullous keratopathy overlying a large placoid gray lesion at the level of the endothelium. Gonioscopy of the left eye found evidence of a membranous development extending from the endothelium to the trabecular meshwork. Examination of her right eye found a perfectly clear cornea and a normal angle. The patient subsequently had Chandler's syndrome diagnosed in the left eye, an iridocorneal endothelial (ICE) syndrome, rather than PPMD. DISCUSSION PPMD and ICE syndromes present with many similarities; these clinical entities are in fact thought to be variants of the same disease. Unlike PPMD, Chandler's syndrome is unilateral, acquired, and typically symptomatic and progressive. It also characteristically affects middle-age women. CONCLUSION Understanding the clinical features of PPMD and ICE syndromes is important in proper diagnosis and management.

Abstract
Neovascular glaucoma (NVG) is a severe form of glaucoma with devastating visual outcome attributed to new blood vessels obstructing aqueous humor outflow, usually secondary to widespread posterior segment ischemia. Invasion of the anterior chamber by a fibrovascular membrane initially obstructs aqueous outflow in an open-angle fashion and later contracts to produce secondary synechial angle-closure glaucoma. The full blown picture of NVG is characterized by iris neovascularization, a closed anterior chamber angle, and extremely high intraocular pressure (IOP) with severe ocular pain and usually poor vision.

Abstract
PURPOSE OF REVIEW Primary angle closure typically causes acute intraocular pressure rise in the phakic elderly. Alternative diagnoses, however, for which iridotomy is usually ineffective, occur commonly in younger, nonhyperopic, and pseudophakic patients. RECENT FINDINGS High-resolution ultrasonography has advanced our understanding of these entities. Management of platueau iris, present in over half of angle closures with patent iridotomy, may depend on disease stage. Early postoperative pseudophakic patients with myopic shift and narrow angle should be treated with laser capsulotomy for capsular block. Bilateral angle closure is usually due to an offending systemic pharmacologic agent, which must be stopped to resolve the closure. Ciliary body swelling often produces angle closure by blocking the access of aqueous to the anterior chamber, sometimes paradoxically after hypotony. Annular choroidal effusions, difficult to detect without ultrasound, may mimic angle closure. Although cycloplegic and corticosteroid therapy may resolve some entities, pars plana vitrectomy and lensectomy may be necessary to resolve severe ciliary block. We also discuss unique variants of angle closure in patients with retinal disease. SUMMARY Atypical angle closures should always be considered. Careful examination techniques and new technology can detect the mechanisms involved and direct treatment.

Abstract
Iridocorneal endothelial (ICE) syndrome is a group of ocular conditions characterized by corneal proliferative endotheliopathy in which secondary corneal edema, peripheral anterior synechiae, and abnormalities of the iris stroma are the common features. The etiology remains unclear, but may be related to viral infection with Herpes simplex or Epstein-Barr virus. The pathogenesis of the ICE syndrome is believed to result from an abnormality of the corneal endothelial cells (causing corneal edema), with secondary spreading of the cells over the trabecular meshwork region (causing anterior synechiae and elevated intraocular pressure [IOP]) and across the surface of the iris (responsible for the formation of iris holes, pupillary distortion, and iris noduli). The disease complex, which includes essential iris atrophy, Chandler's syndrome, and iris nevus (Cogan-Reese) syndrome, is almost always unilateral, nonfamilial, and typically occurs in females during young adulthood. ICE syndrome is commonly progressive and frequently complicated by secondary glaucoma and corneal decompensation. In Chandler's syndrome, iris changes are less pronounced and corneal edema more frequent than in essential iris atrophy or Cogan-Reese syndrome. Glaucoma associated with ICE syndrome is often difficult to manage and is usually treated with medications and/or filtering surgery. Glaucoma filtering surgery is usually successful when done early, but may fail due to endothelialization of the fistula by the abnormal corneal endothelium.

Abstract
AIM To document the ultrasound biomicroscopic (UBM) findings in Chinese patients with iridocorneal endothelial (ICE) syndrome. METHODS 21 patients with ICE syndrome and 15 normal subjects underwent UBM. UBM findings of anterior segment were compared between normal subjects and three clinical types of ICE syndrome: progressive iris atrophy (PIA), Chandler's syndrome (CS), and Cogan-Reese syndrome (CRS). RESULTS Central anterior chamber depth was significantly less in patients with ICE syndrome (2.25 (SD 0.32) mm) than in normal subjects (2.76 (0.32) mm). Peripheral anterior synechiae were observed in all the ICE patients by UBM. Three out of four CRS subjects showed an "arborised" shape of iridocorneal angle. Two eyes out of 10 with CS presented bridge-shaped synechiae. A membrane-like mound was observed in iridocorneal angle in two patients: one with CRS and one with CS. UBM was found to be more effective in detecting peripheral anterior synechiae (PAS) and iris atrophy than slit lamp microscopy and gonioscopy, mainly because of corneal oedema in patients with CS. Four out of 11 patients with unilateral ICE syndrome had shallow or closed anterior chamber angles in their fellow eyes. Two of them successfully responded to laser peripheral iridotomy. CONCLUSIONS UBM is an effective method to reveal the anterior segment features and provides a useful tool in the diagnosis of ICE syndrome. Different subtypes of ICE syndrome may have different UBM manifestations. UBM can help to identify angle closure in the fellow eye of unilateral ICE syndromes.

Abstract
OBJECTIVE To provide data on the results of patients with nonneovascular juvenile glaucoma who had Molteno implant surgery in the province of Otago, New Zealand. DESIGN Prospective noncomparative case series. PARTICIPANTS Fifty-five operations in 52 eyes of 45 patients with nonneovascular juvenile glaucoma who had Molteno implant surgery between the ages of 9 and 49 years from 1976 to 2003 at Dunedin Hospital and were observed for a mean of 12.2 years (range, 0.1-25). INTERVENTION Insertion of a Molteno implant. MAIN OUTCOME MEASURES Intraocular pressure (IOP) and visual acuity (VA). RESULTS Insertion of a Molteno implant controlled IOP at < or =21 mmHg with probabilities of 0.89 (95% confidence interval [CI], 0.81-0.97) at both 1 and 2 years and 0.85 (95% CI, 0.75-0.95), 0.78 (95% CI, 0.66-0.90), and 0.71 (95% CI, 0.58-0.85) at 5, 10, and 15 years, respectively. Mean VA was 20/100 preoperatively; improved to 20/60 at 1 year; and stabilized at 20/120 at 5, 10, and 15 years postoperatively. Twenty-nine eyes had their preoperative VA maintained or improved at final follow-up, and the VAs of 17 eyes deteriorated but were at least light perception at final follow-up. CONCLUSION The use of Molteno implants in cases of nonneovascular juvenile glaucoma controlled IOP with a probability of 0.71 15 years postoperatively, whereas 53% maintained or improved their vision from their preoperative VA at final follow-up.

Abstract
BACKGROUND The different variants of the iridocorneal endothelial (ICE) syndrome were separately described in the early to mid-1900's and were eventually linked to a common etiology of an abnormal corneal endothelium. The ICE syndrome typically manifests in early to middle adulthood, usually occurs in women, and is almost always unilateral. Management of patients with any variant of the ICE syndrome challenges even the best clinicians. CASE REPORT We present a 52-year-old patient with Chandler's syndrome. Our patient shared many of the classic characteristics of Chandler's syndrome, including peripheral anterior synechiae and corneal edema, with one unusual aspect--the patient was male. Details regarding the subsets of the ICE syndrome, differential diagnosis, and current understanding of the pathophysiology are also reviewed. CONCLUSION The ICE syndrome is a progressive anterior segment disease that is quite difficult to manage. Corneal edema, increased IOP, and glaucoma are all sequelae of these conditions and, even in the best hands, are extremely challenging to manage. Today, nearly 100 years after Harms described the first patient with an ICE syndrome, we still do not know the exact mechanism for the corneal endothelial changes. Many investigations have been made into the causative agent or stimulus for abnormal endothelial growth in the ICE syndrome. No definitive proof has been established, but a relationship may exist with the Herpes Simplex and Epstein-Barr viruses. Further investigation is needed to determine the most-appropriate treatment and management of the ICE syndrome.

Abstract
PURPOSE To report the long-term outcomes of patients with iridocorneal endothelial (ICE) syndrome who required surgery for glaucoma. DESIGN Retrospective, noncomparative case series. PARTICIPANTS Twenty-six patients with ICE syndrome who underwent surgery for glaucoma at one institution between January 1987 and January 2000. MAIN OUTCOME MEASURES Intraocular pressure (IOP), visual acuity, number of glaucoma medications, and further surgical interventions were measured. RESULTS Five eyes had a trabeculectomy with an antifibrotic agent alone, seven eyes had a trabeculectomy with an antifibrotic agent and a subsequent glaucoma drainage implant (GDI), and 14 eyes had a GDI alone. In eyes that underwent a trabeculectomy with an antifibrotic agent, preoperative IOP was reduced from a mean of 38.8 +/- 10.5 mmHg on 2.3 +/- 0.8 glaucoma medications to a mean of 11.8 +/- 4.3 mmHg on 1.2 +/- 1.4 medications at last follow-up after surgery (83.8 +/- 40.3 months). In eyes that underwent GDI surgery, preoperative IOP was reduced from a mean of 35.2 +/- 13.0 mmHg on 2.0 +/- 1.3 glaucoma medications to a mean of 8.7 +/- 11.2 mmHg on 1.2 +/- 1.1 medications at last follow-up after surgery (50.5 +/- 40.7 months). Twenty-four eyes (92%) had an IOP less than 22 mmHg, and 22 eyes (85%) had visual acuity 20/400 or better at last follow-up (55.8 +/- 41.5 months). Mean number of glaucoma surgeries per patient over the follow-up period was 1.6 +/- 1.2. Trabeculectomy with antifibrotic agents had a survival of 73% at 1 year, 44% at 3 years, and 29% at 5 years. Glaucoma drainage implants had a survival of 71% at 1 year, 71% at 3 years, and 53% at 5 years. CONCLUSIONS Glaucoma associated with ICE syndrome can be managed successfully surgically, although multiple procedures are often needed.

Abstract
PURPOSE Eyes with iridocorneal endothelial (ICE) syndrome have a high risk of failure in glaucoma filtering surgery failing. We investigated the efficacy of trabeculectomy with intraoperative mitomycin-C application in these patients. DESIGN Retrospective nonrandomized comparative trial with historical controls. PARTICIPANTS AND CONTROLS Ten patients with unilateral iridocorneal endothelial (ICE) syndrome were reviewed. Their intraocular pressures could not be controlled medically. In five eyes, this was the primary surgery performed. Five of the patients had undergone prior intraocular pressure-(IOP) lowering surgery that had failed at the time enrolled. Results were compared with previously published case series of similar patients treated with trabeculectomy alone or trabeculectomy and subconjunctival 5-fluorouracil injections. INTERVENTION Intervention consisted of trabeculectomy with a limbus-based conjunctival flap and mitomycin-C application. The dosage of mitomycin-C was 0.4 mg/ml for 1 to 4 minutes (mean, 1.9 min). MAIN OUTCOME MEASURES Adequate control of IOP (without medication lower than 21 mm Hg). RESULTS In eight eyes the IOP remained well controlled (mean IOP, 12.1 mm Hg) over the entire length of available of follow-up (mean, 14.9 months). Two eyes required implantation of an aqueous tube shunt at 4 and 11 months, respectively, after trabeculectomy with mitomycin-C. One eye experienced visual loss of 3 Snellen lines because of hypotony maculopathy. CONCLUSIONS Trabeculectomy with mitomycin-C application offers a reasonable intermediate-term success rate in ICE patients, who are otherwise at high risk for failure of filtering surgery.
