Abstract
AimTo develop a predictive model for the diagnosis of iris melanoma. METHODS Retrospective consecutive case series that included 100 cases of pathologically confirmed iris melanoma and 112 cases of Iris naevus, either pathological confirmation or documented stability of >1 year. Patient demographic data, features of clinical presentation, tumour characteristics and follow-up were collected. Iris melanoma with ciliary body extension was excluded. Lasso logistic regression with 10-fold cross-validation was used to select the tuning parameter. Discrimination was assessed with the area under the curve (AUC) and calibration by a plot. RESULTS There was a significant asymmetry in the location of both nevi and melanoma with preference for inferior iris quadrants (83, 74%) and (79, 79%), respectively (p=0.50). Tumour seeding, glaucoma and hyphaema were present only in melanoma. The features that favoured the diagnosis of melanoma were size (increased height (OR 3.35); increased the largest basal diameter (OR 1.64)), pupillary distortion (ectropion uvea or corectopia (OR 2.55)), peripheral extension (angle or iris root involvement (OR 2.83)), secondary effects (pigment dispersion (OR 1.12)) and vascularity (OR 6.79). The optimism-corrected AUC was 0.865. The calibration plot indicated good calibration with most of the points falling near the identity line and the confidence band containing the identity line through most of the range of probabilities. CONCLUSIONS The predictive model provides direct diagnostic prediction of the lesion being iris melanoma expressed as probability (%). Use of a prediction calculator (app) can enhance decision-making and patient counselling. Further refinements can be undertaken with additional datasets, forming the basis for automated diagnosis.

Abstract
Primary uveal melanoma is rare and affects approximately 8,000 persons per year worldwide. This malignancy can involve the iris, ciliary body, and choroid. Of these three structures, the iris is the least commonly affected site, representing only 4% of all uveal melanomas. Iris melanoma can arise from iris melanocytic nevus, iris melanocytosis, or de novo. In a longitudinal study of 1,611 patients with iris nevus, transformation into melanoma, using Kaplan-Meier estimates, was found in 2.6% by five years and in 4.1% by 10 years. The factors that predicted growth of iris melanocytic nevus into melanoma are denoted by a letter (ABCDEF) guide: A for age ≤40 years old at presentation (hazard ratio [HR] = 3, P = .01), B for blood (hyphema) (HR = 9, P < .0004), C for clock hour of tumor inferiorly (tumor location) (HR = 9, P = .03), D for diffuse flat tumor configuration (HR = 14, P = .02), E for ectropion uveae (HR = 4, P = .002), and F for feathery ill-defined margins (HR = 3, P = .02). At diagnosis, iris melanoma has a mean cross-sectional diameter of 5.5 mm and thickness of 2.1 mm, often with tumor seeding (28%) and secondary glaucoma (35%). We provide a comprehensive review of iris nevus and melanoma to explore relevant demographic and clinical data, risk factors for tumor growth, management, and prognosis, with the hope that clinicians will be more comfortable in understanding this rare malignant condition.

Abstract
Uveal melanoma prognostication studies have mainly included posterior uveal melanomas located in the ciliary body and choroid, often excluding iris melanoma. In this study, we report prognostic status and survival outcomes in a series of 35 patients with biopsy-proven iris melanoma. Fluorescence in situ hybridization was performed in 10 (29%) cases and 2 (5%) underwent multiplex ligation-dependent probe amplification. In total, 9 cases demonstrated disomy 3, 2 cases with monosomy 3 (fluorescence in situ hybridization), and 1 had a technical failure. On gene expression profile testing, 20 of the 23 cases (90%) were gene expression profile class 1A, and the remaining 3 (10%) were class 1B. No patient had a Class 2 status. The median follow-up period was 49 months (mean 59, range 2-156 months). No metastasis was reported during follow-up, and metastasis-free survival was 100%. A review of the published literature revealed 47 cases with high-risk status on molecular prediction, of which only 6 (13%) developed metastasis. Ciliary body involvement was reported in 5 cases and was unknown in 2 cases. We conclude that molecular prognostication of iris melanoma demonstrates low-risk prognostic status in the majority of cases irrespective of the technique used. Even those with high-risk status do not develop metastasis unless the tumor involves the ciliary body.

Abstract
BACKGROUND The Cancer Genome Atlas (TCGA) classification of genetic alterations in uveal melanoma is widely used for prognostication. We present novel observations on the impact of TCGA Group specifically for iris melanoma. METHODS This was a retrospective cohort study at a tertiary referral ocular oncology center. All patients with a diagnosis of iris melanoma who underwent genetic evaluation and assessment for TCGA classification between 20 November 1995 and 5 April 2021 were included. The main outcome measures were visual acuity, secondary glaucoma, tumor recurrence, melanoma-related metastasis and death per TCGA group. RESULTS There were a total of 78 patients included. The mean patient age was 49.6 years (median 53.0, range 3.0-85.0), mean tumor basal diameter was 6.7 mm (median 6.0, range 1.5-22.0), and mean tumor thickness was 2.6 mm (median 2.5, range 0.5-8.5). Cytology results confirmed iris melanoma (93%) or were inconclusive (7%). The TCGA groups included Group A (n = 36, 46%), Group B (n = 7, 9%), Group C (n = 34, 44%), and Group D (n = 1, 1%). There was no statistically significant difference in outcomes of visual acuity, tumor thickness reduction, secondary glaucoma, tumor recurrence, melanoma-related metastasis or death per individual TCGA group (A vs. B vs. C vs. D) and per bimodal comparison (A/B vs. C/D). CONCLUSIONS In this analysis, iris melanoma was classified as TCGA group A or B in 55% and as C or D in 45%. The TCGA classification was not predictive of melanoma-related metastasis or death.

Abstract
We report an unusual case of an amelanotic melanoma in a 7 year old hispanic child with subclinical globe perforation. Uveal melanoma rarely occurs in children. Young affected patients are mostly light-colored eye Caucasian adolescents. Since they are not common, these tumors are usually not recognized and misdiagnosed. Differential diagnoses and therapeutic options are outlined.

Abstract
PURPOSE To report on the clinical characteristics and outcomes for patients with iris melanoma using proton therapy. DESIGN Retrospective study. PARTICIPANTS One hundred seven patients with iris melanoma from 3 regional ophthalmologic centers. METHODS A retrospective study was conducted for iris melanoma patients from 3 regional ophthalmologic centers referred to and treated at a single proton therapy facility between 1996 and 2015. MAIN OUTCOME MEASURES At each follow-up visit, examinations included measurement of best-corrected VA, slit-lamp, examination, indirect ophthalmoscopy, and ultrasound biomicroscopy. RESULTS With a median follow-up of 49.5 months, 5 of 107 patients experienced a local relapse within a median of 36.3 months. The cumulative incidence of relapse was 7.5% at 5 years. All 5 patients showed involvement of the iridocorneal angle (P = 0.056). Diffuse iris melanoma showed a higher risk of relapse (P = 0.044). Four patients showed out-of-field relapse and 1 showed angular relapse. Three patients were retreated with proton therapy, whereas 2 other patients, one with T1b disease and another with diffuse T3 disease, underwent secondary enucleation. None of the patients experienced metastases nor died of iris melanoma. Vision improved in 59.4% of patients (n = 60/101). However, cataracts occurred in 57.4% of the 54 patients (n = 31) without cataract or implant at diagnosis. Secondary glaucoma was reported in 7.6% of the patients (n = 8), uveitis in 4.7% (n = 5), and hyphema in 3.7% (n = 4). All but 5 cases of complications were mild, transient, and not sight limiting after treatment. Five cases of glaucoma, including 1 with uveitis, were severe and associated with visual deterioration. CONCLUSIONS Proton therapy showed efficacy and limited morbidity in iris melanomas.

Abstract
PURPOSE To determine clinical features predictive of growth of iris nevus into melanoma. DESIGN Retrospective, comparative case series. PARTICIPANTS A total of 1611 consecutive patients referred to an ocular oncology center with iris nevus. INTERVENTION Observation and photographic documentation. MAIN OUTCOME MEASURES Growth into melanoma. RESULTS The mean age at referral for iris nevus was 51 years (median, 54; range, <1-94 years). At presentation, the mean tumor basal diameter was 3 mm (median, 3 mm; range, <1-12 mm) and mean tumor thickness was 0.8 mm (median, 0.5 mm; range, 0-5 mm). All patients were initially diagnosed with benign iris nevus. Growth of iris nevus to melanoma was confirmed in 2% of eyes (n = 27) over a mean follow-up of 68 months (median, 46 months; range, 3-465 months). By Kaplan-Meier estimates, iris nevus growth to melanoma occurred in <1%, 3%, 4%, 8%, and 11% at 1, 5, 10, 15, and 20 years, respectively. Factors predictive of iris nevus growth to melanoma by multivariable analysis included age ≤ 40 years at presentation (hazard ratio [HR], 3), episode of hyphema (HR, 9), 4:00 to 9:00 clock hour location of tumor (HR, 9), diffuse tumor (involving entire iris surface) (HR, 14), ectropion uveae (HR, 4), and feathery tumor margins (HR, 3). Additional important factors by univariable analysis included tumor seeding on the iris or in the anterior chamber angle, feeder vessels, and nodule formation. These factors can be remembered using the mnemonic ABCDEF, representing A = age young, B = blood, C = clock hour inferior, D = diffuse, E = ectropion, and F = feathery margin. CONCLUSIONS In an analysis of 1611 cases of iris nevus referred for evaluation at an ocular oncology center, growth into melanoma occurred in 8% by 15 years. Risk factors for growth, identified by ABCDEF included Age young, Blood (hyphema), Clock hour inferior, Diffuse configuration, Ectropion uveae, and Feathery tumor margin.

Abstract
PURPOSE To determine the clinical and ultrasound biomicroscopy (UBM) features associated with growth in iris melanocytic lesions. STUDY DESIGN Retrospective case series analysis. METHODS We included all iris melanocytic lesions that were monitored between January 2005 and November 2009. At the end of the analysis, 44 eyes of 44 patients were included in the final analysis. The clinical features analyzed were: iris color, largest base diameter, radial location of the lesion epicenter, circumferential location of the lesion epicenter, lesion configuration, lesion pigmentation, intrinsic vascularity within the lesion, presence of associated pigmentation, the impact on the pupil, presence of iris atrophy, and lesion-induced localized cataracts. The UBM features included lesion thickness, presence of corneal touch, presence of surface plaque, internal structure, and internal reflectivity. Regression analysis was performed to define the features associated with growth. RESULTS Twenty-three percent of the lesions showed documented growth. Mean follow-up was 21.4 months (range: 10-48). Clinical features associated with growth were a large basal diameter at baseline (P = .004) and inferior location (P = .004). UBM features associated with growth were: a greater baseline thickness (P = .01), presence of corneal touch (P = .007), an irregular internal structure (P = .0001), and the presence of dots and linear streaks (P < .0001). Clinical features that were not associated with growth were the radial location of the lesion in the iris (P > .999), lesion configuration (P > .999), lesion pigmentation (P > .999), the presence of pigment dispersion (P = .70), iris freckles (P = .15), corectopia (P > .999), ectropion (P > .999), and intrinsic vascularity (P = .70). UBM features not associated with growth were the presence of a surface plaque (P = .07) and the internal reflectivity (P = .77). CONCLUSION Substantial growth in iris melanocytic lesions is associated with original larger basal diameter and inferior lesion location. On UBM growth is associated with greater original thickness, presence of corneal touch, and an irregular internal structure. Presence of these features could modify the frequency of observation of those lesions.

Abstract
PURPOSE To evaluate outcome of surgical resection of iris and irido-ciliary melanomas. METHOD Retrospective analysis of all cases treated in Denmark 1975-1999 with clinical follow-up in 2002 and death certificate analysis in 2008. A quality of life questionnaire was completed at follow-up. RESULTS A total of 53 patients were identified. Of these, 47 were examined at follow-up. Median observation time was 7.15 years (range 0.3-27.4 years). Five patients had died of nonmelanoma causes, and one could not be reached because of immigration. None of the patient had melanoma metastases, and none had died of melanoma-related causes. Only one patient had a local recurrence, which was successfully treated by cryotherapy. The quality of life-related questions demonstrated that most patients (40) suffered from photophobia, and eight patients had changed their driving habits, not driving at night time. However, none had changed job as a consequence of the surgical treatment. Only two patients were emotionally affected by the diagnosis of iris melanoma. CONCLUSION Resection of small iris and irido-ciliary melanomas is a safe and efficient procedure, provided that strict diagnostic and surgical procedures are followed and the preoperative intraocular pressure is normal.

Abstract
PURPOSE To evaluate iris melanoma in children versus adults. METHODS Retrospective, nonrandomized clinical case series including all patients with a clinical diagnosis of iris melanoma managed at the Ocular Oncology Service at Wills Eye Institute over 40 years. Patients were divided into three age categories based on age at presentation: children (≤ 20 years), mid-adults (21-60 years), and older adults (>60 years). The clinical features, treatments, and outcomes were statistically analyzed based on patient age at presentation. The main outcome measures were melanoma features and related metastasis and death. RESULTS Of 8,101 eyes with uveal melanoma, there were 317 (4%) with iris melanoma, including 24 (8%) children (≤ 20 years), 187 (59%) mid-adults (21-60 years), and 106 (33%) older adults (>60 years). There was no age-related difference in race, sex, tumor quadrant, thickness, pigmentation, associated corectopia, ectropion uveae, hyphema, or extraocular extension. Significant age-related differences were found with mean tumor basal diameter, tapioca appearance, mean intraocular pressure, secondary glaucoma, tumor seeding in angle, and mean number of clock hours of angle seeding. Multivariate analysis of factors predictive of metastasis included extraocular extension and high intraocular pressure. Factors predictive of death included increased tumor thickness and high intraocular pressure. There was no difference in metastasis or death by age group. CONCLUSIONS Iris melanoma shows significant clinical differences in children versus adults, with smaller tumor size, less tumor seeding in angle, and lower incidence of secondary glaucoma. There was no significant difference in metastasis or death by age group.

Abstract
PURPOSE To evaluate the observed and relative survival of patients diagnosed with a malignant melanoma in the ocular region in Denmark during the period 1943-97. METHODS The study included 2,504 patients (1,292 men and 1,212 women) diagnosed with a melanoma in the ocular region, of which 2,434 cases could be topographically subclassified into 2,178 in the choroid/ciliary body, 141 in the iris, and 115 in the conjunctiva. The patients were followed through 2002 and the observed survival proportions and relative survival ratios were estimated. RESULTS For the total ocular region and the choroid/ciliary body, the observed survival did not vary statistically significantly with the year of diagnosis. A statistically insignificant higher observed survival for women than men was found for tumors in the ocular region and the subgroups choroid/ciliary body, iris, and conjunctiva. During the 55-year study period, the 5- and 10-year relative survival remained stable for the ocular region for men at 67% and 57% and for women at 71% and 60%, respectively, and stable for the choroid/ciliary body for men at 66% and 55% and for women at 69% and 57%, respectively. The 5- and 10-year relative survival for the iris was for men 90% and 85% and for women 99% and 101%, respectively, and for the conjunctiva for men 83% and 70% and for women 93% and 82%, respectively. CONCLUSION The observed and relative survival of patients diagnosed with a melanoma in the ocular region and choroid/ciliary body in Denmark during the period 1943-97 and followed through 2002 has remained stable. The highest observed and relative survival was found for iris melanomas, the lowest for choroid/ciliary body melanomas, and intermediate for conjunctival melanomas.

Abstract
The iris is the least common site of primary uveal melanoma. The prognosis of iris melanoma is better than that of melanoma of the ciliary body and choroid, but the reason for this difference is unclear. One possible explanation is that iris melanoma is smaller than its posterior segment counterparts at the time of diagnosis. Most iris melanomas are spindle cell types, according to a modified Callender classification system. There is evidence that the proliferation of melanocytes of the anterior iris surface (iris plaque) and diffuse stromal invasion may be risk factors for local recurrence and metastasis, respectively.

Abstract
AIMS To describe the results in terms of local control, eye preservation and systemic evolution of iris melanomas treated by proton beam irradiation. METHODS Retrospective review of the charts of patients with iris melanoma treated by proton beam therapy between April 1998 and September 2002. Ciliary body melanomas with iris involvement or tumours with extrascleral invasion were excluded. Treatment consisted of 60 Gy of proton beam irradiation delivered in four fractions to the tumour volume. RESULTS A total of 21 patients were treated, median follow-up of 33 months (8-72 months). 15 patients presented a lesion with documented growth. The median clinical diameter was 5 mm (2-8 mm), the median ultrasound diameter 4.8 mm (2-7.7 mm) The patients were 6% T1, 57.1% T2, and 14.3% T3 all N0M0. The iridocorneal angle was invaded by the tumour in 71.4% of patients. At the end of follow-up, all patients were alive with no proven metastatic disease except one patient with suspicious liver lesions. None of the patients showed tumour progression or ocular relapse. The tumour response at 2 years was a flat lesion for 6.3% of cases, partial regression in 75% and stable in 18.8%. None of the patients required secondary enucleation. The main complication was cataract (45% within 24 months of treatment). Raised intraocular pressure was observed in 15% of patients but no neovascular glaucoma. CONCLUSIONS Proton beam therapy shows potential utility for selected cases of localised iris melanomas allowing excellent local tumour control and eye preservation. Further follow-up on larger series is needed to confirm these results.

Abstract
Uveal melanoma is the most frequent primary malignant intraocular tumor of adults. Among various non-modifiable risk factors, Caucasian race seems to be the most significant with light skin color, blond hair, and blue eyes being specific risk factors. The racial predisposition to uveal melanoma have been explained on the basis of susceptibility of Caucasian race to oncogenic effects of sunlight. Although there is ample evidence in support of this hypothesis in regard to skin melanoma, the evidence in regard to uveal melanoma is insufficient and contradictory. In the following review, we examine physiologic, epidemiological, and genetic data in order to determine the role of sunlight exposure in the pathogenesis of uveal melanoma.

Abstract
The most common anterior segment tumors are primary neuroepithelial cysts, uveal melanomas, metastatic tumors, and benign tumors. In the majority of cases, the diagnosis can be made utilizing a careful clinical history and ocular examination. Ultrasound examination (low and high frequency) has become an indispensable tool used to determine tumor extension and involvement of the surrounding structures. In particular, high-frequency ultrasound has been used to uncover iris pigment epithelial cysts, to allow for the diagnosis of small ciliary body melanomas, and to measure tumors for plaque radiation planning. Whereas fluorescein angiography and computerized tomography have come to play a limited role, fine-needle aspiration biopsy has been found to be quite helpful in selected cases. Once the diagnosis is established, treatment decisions depend on the tumors' location, size, local extension, patterns of growth, and secondary complications. Most anterior segment tumors can be observed for growth prior to treatment. Other options include local resection (iridectomy, lamellar sclerouvectomy, or eye-wall resection) and radiation (ophthalmic plaque or external beam). Enucleation is typically employed if these eye- and vision-sparing treatments are not possible and for uncontrollable secondary glaucoma. This review examines the unique role of high-frequency ultrasonography for the diagnosis and treatment of anterior segment tumors as well as an overview of clinical practice.

Abstract
BACKGROUND Ring melanoma of the ciliary body is a rare variant of uveal melanoma that has a poor prognosis. Only isolated cases have been reported in the literature. METHODS A retrospective review of the clinical features, management, histopathology, and prognosis of 23 consecutive patients with ring melanoma of the ciliary body was performed. RESULTS Of 8,800 patients with uveal melanoma treated on the Oncology Service at Wills Eye Hospital over a 25-year period, only 23 patients (0.3%) were found to have ring melanoma of the ciliary body. The mean patient age was 59 years (median, 63 years; range, 8-81 years). The only visual symptom was blurred vision in 17 patients (74%), and the other six patients (26%) were asymptomatic. At the initial presentation elsewhere, melanoma was recognized in 13 cases (57%). In the remaining 10 cases (43%), the initial clinical diagnosis was glaucoma in three (13%), iris nevus in three (13%), cataract in two (9%), ciliary body detachment in one (4%), and iridocyclitis in one (4%). The patients were observed elsewhere for a mean of 3 months before the diagnosis of melanoma was suspected and referral to Oncology Service was made. On examination, the tumor involved a mean of eight clock hours of the ciliary body. Seven patients (30%) had complete circumferential (360 degrees) involvement of the ciliary body, and 16 (70%) had incomplete (180-360 degrees) ring involvement. The mean tumor thickness was 8 mm. Associated findings included neovascularization of the iris in one case (4%), shallow anterior chamber in 11 (48%), anterior chamber inflammation in five (22%), cataract in nine (39%), lens indentation in eight (35%), and lens subluxation in three (13%). A prominent episcleral (sentinel) vessel (17 cases, 74%), multilobulation of the mass (19 cases, 83%), blockage of light on transillumination (23 cases, 100%), and ultrasonographic hollowness with intrinsic pulsations (23 cases, 100%) were important features differentiating this tumor from simulating conditions. The tumor was managed with enucleation in all 23 patients. Histopathologic studies revealed epithelioid cell-type melanoma in two patients (9%), mixed cell-type in 17 (74%), and spindle cell-type in four (17%). Extraocular extension was present in eight patients (35%). Metastasis developed in 12 of 23 patients (52%) after a mean follow-up of 55 months. CONCLUSIONS Ring melanoma of the ciliary body is a rare tumor that can remain hidden from ophthalmoscopic examination. Certain features, such as prominent episcleral sentinel vessels, multilobulation of the mass, light blockage on transillumination, and ultrasonographic hollowness with intrinsic vascular pulsations, suggest the diagnosis. The life prognosis is poor.

Abstract
Uveal melanoma is the most common primary intraocular malignant tumour, with an annual incidence of approximately six cases per million per year. Approximately 40% of patients with posterior uveal melanoma develop metastatic melanoma to the liver within 10 years after initial diagnosis. Despite high accuracy of diagnosis and availability of various methods of treatment; the mortality due to uveal melanoma has remained unchanged. The prognosis in uveal melanoma depends on clinical, histopathological and cytological factors. Clinical factors that relate to prognosis include location, size, and configuration of the tumour. Uveal melanoma can arise in the iris, the ciliary body or the choroid. Iris melanomas have the best prognosis and ciliary body melanomas have the worst prognosis. Based on retrospective studies, the mortality rates for uveal melanoma for comparable sized tumours treated by enucleation or other globe conserving methods such as radiotherapy appear to be similar. Histopathological factors such as cell type, mitotic activity, microcirculation architecture, tumour-infiltrating lymphocytes and the presence of extrascleral extension are also significant predictors of survival. More recently, cytological factors such as cell proliferation, cytogenic, and molecular genetic prognostic markers have been identified with the hope of detecting high risk cases for adjuvant systemic immune therapy or chemotherapy. At present, the role of these therapeutic methods is not clearly established.

Abstract
OBJECTIVE To identify risk factors that predict distant metastases of iris malignant melanoma. DESIGN Retrospective case series. PARTICIPANTS The participants included 169 consecutive patients with microscopically confirmed iris malignant melanoma managed on the Oncology Service at Wills Eye Hospital between 1974 and 1999. MAIN OUTCOME MEASURES The main outcome measure was the development of distant tumor metastasis. Cox proportional regression models were used to calculate the risk of eventual metastatic spread. RESULTS Of 1054 patients referred with suspicious iris melanocytic tumors (rule out malignant melanoma) over a 25-year period, 169 patients (16%) had microscopically proven iris melanoma, and the remainder (84%) had clinically diagnosed iris nevus. Of the patients with iris melanoma, the mean age at the time of diagnosis was 43 years (median, 45 years; range, 1-90 years). All patients were Caucasian. The mean tumor base was 6 mm (median, 5 mm; range, 1-17 mm), and mean tumor thickness was 2 mm (median, 2 mm; range, 1-4 mm). The mean number of clock hours of tumor involvement in the iris was four, tumor seeding on the iris was four, and tumor seeding into the anterior chamber angle was four. Extraocular extension was present in 10 eyes (6%). The tumor management consisted of local resection (iridectomy, iridocyclectomy, or iridocyclogoniectomy) in 102 patients (60%), enucleation in 51 (30%), plaque radiotherapy in 9 (5%), and observation in 7 patients (4%). Metastasis developed in nine patients (5%). Using Kaplan-Meier life table analysis, metastasis was found in 3% of patients at 5 years, 5% at 10 years, and 10% at 20 years. The clinical factors at initial evaluation predictive of eventual metastasis from iris melanoma included increasing age at diagnosis (P = 0.03), elevated intraocular pressure (P = 0.03), posterior tumor margin at angle or iris root (versus midzone) (P = 0.02), extraocular extension (P: = 0.02), and prior surgical treatment of the tumor elsewhere before referral (versus observation) (P = 0.006). The method of management (resection, radiotherapy, or enucleation) did not have an impact on metastasis. CONCLUSIONS Microscopically confirmed iris melanoma demonstrates distant metastasis in 5% of patients at 10 years follow-up. Metastases are more likely to develop in those patients who are older and show tumor features of iris root/angle location with elevated intraocular pressure and extraocular extension.

Abstract
Twenty patients with malignant uveal melanoma were treated at the The Svedbergh cyclotron in Uppsala from 1989 to 1991. Each tumour received a total dose of 54.6 Gy in four equal fractions on four following days. After treatment the melanoma in all eyes showed decrease in size combined with irradiation retinopathy. In eight patients the treatment was successful after five years. Nine eyes had to be enucleated, two due to recurrence and seven due to neovascular glaucoma. Three patients died, two from metastases and one from heart disease. In all patients the visual acuity was dependent on the distance between the irradiation field and the macula or optic nerve. Each patient suffered from transient post irradiation skin erythema and permanent loss of eyelashes and eyebrows when these were included in the irradiation field. The development of secondary glaucoma was positively correlated with tumour volume, but not to the age or sex of the patients. Histological examination of all the enucleated eyes revealed residual viable tumour without obvious radiation damage: mitotic figures were not identified. MRI examination, performed before and after treatment, demonstrated a marked shift in water binding properties after irradiation. The final visual acuity was dependent on the location of the tumour.

Abstract
PURPOSE To illustrate some management problems with pigmented iris tumors. METHODS This is a retrospective analysis of 234 iris tumors managed by one of the authors. Five patients were selected whose clinical course and pathologic data illustrate diagnostic problems that can occur with these tumors. RESULTS In the patients described, diagnostic problems were noted. In two patients, glaucoma specialists were unable to correctly diagnose an iris melanoma before filtration. One patient had a 3-clock-hour iris biopsy that was not diagnostic for malignancy, yet the enucleated eye showed melanoma. One patient with a clinically stable iris tumor had a mixed-cell melanoma. CONCLUSIONS Most iris-pigmented tumors have a benign disease course. In some case, despite little clinical evidence of disease activity or progression, a melanoma, often with epithelioid cells, may be present and neither a fine-needle nor an open biopsy is always diagnostic.
