Focal choroidal excavation associated with nonmelanocytic iris tumor.

PURPOSE: To describe a unique unilateral association between an iris stromal tumor and a macular focal choroidal excavation. CASE DESCRIPTION: A 40-year old patient presented with a small iris tumor associated with a unilateral macular lesion disclosed during a routine ophthalmologic examination. The patient was asymptomatic and visual function was not affected. After clinical and instrumental evaluation, a diagnosis of nonmelanocytic undefined stromal tumor of the iris associated with macular focal choroidal excavation was made. The size and shape of the two lesions remained stable during a 7-year follow-up and the patient did not develop other signs. CONCLUSION: The concurrent presence of a stromal iris tumor associated with focal choroidal excavation has never been reported. Further reports of this association are required in order to understand its exact pathogenesis.

Spontaneous microscopic hyphema secondary to iris vascular tufts: Case report with video documentation.

A 71-year-old woman presented with spontaneous microhyphema in her left eye, causing blurry vision. Bleeding stopped spontaneously shortly after several cycles of digital compression on the upper eyelid, (which were documented in video), and therefore, did not require laser photocoagulation, a possible approach previously explained to the patient. A microhemangioma at the edge of the iris was identified to be the cause of the condition. The hemorrhage did not recur during the follow-up period (9 months).

Amelanotic iris melanoma in a 7 year-old hispanic boy with subclinical globe perforation. / Melanoma amelanótico del iris en un niño hispano de 7 años con perforación del globo subclínica.

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.

Metástasis a iris como primera manifestación de adenocarcinoma pulmonar / Iris metastasis as a first manifestation of lung adenocarcinoma

OBJETIVO: Describir un caso de adenocarcinoma pulmonar que comenzó clínicamente como una metástasis en iris. CASO CLÍNICO: Paciente varón de 76 años de edad que acude a consulta por notar una pequeña «mancha rosada» en su ojo derecho. A la exploración con biomicroscopía se encontró una masa en el iris. La evaluación sistémica subsiguiente del paciente mostró un adenocarcinoma del pulmón izquierdo. DISCUSIÓN: A pesar de la infrecuencia de las metástasis de iris secundarias a cáncer pulmonar, debe de tomarse en cuenta en el diagnóstico diferencial de masas tumorales iridianas

OBJECTIVE: To describe a case of lung adenocarcinoma for which the first clinical manifestation was an iris metastasis. CASE REPORT: A 76-year-old male patient came for consultation referring a «pinkish speck» on his right eye. On biomicroscopy examination, a mass was found on the iris of the right eye. Subsequent systemic work-up of the patient revealed a left lung adenocarcinoma. DISCUSSION: Although uncommon, iris metastasis secondary to lung cancer should be part of differential diagnosis in iris tumours

Melanomalytic glaucoma secondary to iris melanoma. / Glaucoma melanomalítico secundario a melanoma de iris.

CLINICAL CASE: A 35-year-old male with unilateral ocular hypertension in the right eye (RE). Anterior segment examination of the RE showed a melanotic lesion. Intraocular pressure (IOP) was 40mmHg in RE. Gonioscopy revealed extension into the anterior chamber angle. Excisional biopsy was performed and consistent with iris melanoma and secondary melanomalytic glaucoma. Brachytherapy was performed as adjuvant therapy. DISCUSSION: In patients presenting with unilateral glaucoma and increased pigmentation in the trabecular meshwork, it is crucial to perform imaging studies. Resection by iridectomy with adjuvant episcleral brachytherapy is effective in controlling the disease.

Results in Combined Cataract Surgery With Prosthetic Iris Implantation in Patients With Previous Iridocyclectomy for Iris Melanoma.

PURPOSE: To present visual and functional results following implantation of iris prosthesis combined with cataract surgery in eyes with previous iridocyclectomy for iris melanoma or presumed iris melanoma. DESIGN: Retrospective noncomparative case series. METHODS: Sixteen patients (16 eyes) with iris defects after iridocyclectomy for iris melanoma in 15 cases and iris adenoma in 1 case underwent prosthetic iris device implantation surgery. Prosthetic iris implantation was combined with phacoemulsification and intraocular lens (IOL) implantation. The visual acuity, subjective glare and photophobia reduction, anatomic outcome, and complications were reviewed. RESULTS: Best-corrected visual acuity was improved in 13 eyes (81.25%), remained stable in 2 eyes (12.25%), and decreased in 1 eye (6.25%). Photophobia and glare improved in every case except for 1 (93.75%). Notably, after surgery 12 patients (75.00%) reported no photophobia and 10 patients (62.50%) reported no glare. The median postoperative follow-up was 29.5 months, with a minimum of 5 months and a maximum of 189 months. All iris devices were in the correct position, and all eyes achieved the desired anatomic result. The IOL optic edges were covered in all areas by either residual iris or opaque portions of a prosthetic iris device. CONCLUSIONS: In patients who have undergone previous iridocyclectomy for presumed iris melanoma, combined cataract surgery and iris prosthesis placement, with or without iris reconstruction, can lead to visual improvement as well as reduction of both glare and photophobia.

[A woman with iris heterochromia]. / Een vrouw met irisheterochromie.

A 20-year-old woman with congenital iris heterochromia presented with loss of vision of her right eye. We made de diagnosis of a large 'uvea melanoma' and enucleated the eye. Pathological examination showed an underlying oculodermal melanocytosis (ODM). The life-time risk of uveal melanoma in the general population is 0.7:100,000, but 1:400 in patients with ODM. Therefore, annual fundoscopy is recommended in these patients.

Análisis ultrabiomicroscópico de quistes iridianos / Ultrasound biomicroscopic analysis of iris cysts

OBJETIVO: Describir los hallazgos ultrabiomicroscópicos y complicaciones de pacientes con quistes iridianos. DISEÑO: Serie de casos, restrospectivo. MÉTODO: Se incluyó a 13 pacientes con diagnóstico de quistes de iris, confirmado mediante ultrabiomicroscopia (UBM) en un periodo de 10 años (2002-2012) en un centro oftalmológico de la ciudad de México. Se incluyeron datos demográficos, historia clínica médica y ocular, características clínicas y ultrabiomicroscópicas (tipo, número, localización y hallazgos acústicos), así como complicaciones asociadas. Se realizó un análisis descriptivo, incluyendo medias y desviación estándar. RESULTADOS: La distribución por sexo fue 8 mujeres y 5 hombres, con edad promedio de 44,5 años ± 15,5 (rango de 6 a 70 años). El 92,3% fueron quistes del epitelio pigmentado y 7,7% del estroma; el 76,9% se encontraron en la periferia y 69,2% entre los meridianos de las II y las VI horas del reloj. Todos los quistes mostraron una pared con reflectividad moderada a alta. El 38,5% presentó complicaciones (el 15,4% cierre parcial del ángulo camerular; el 15,4% glaucoma secundario de ángulo cerrado y el 7,7% discoria). CONCLUSIONES: La mayoría de los quistes de iris son derivados del epitelio pigmentado, de curso benigno y con una baja tasa de complicaciones. La UBM es una herramienta indispensable que nos permite planear tratamientos localizados, específicos, más conservadores y menos destructivos, con un daño potencial menor de las estructuras oculares y, por lo tanto, mejor pronóstico visual

PURPOSE: To describe the ultrasound biomicroscopic (UBM) features and complications associated with iris cysts. DESIGN: A retrospective case series. METHODS: Thirteen patients with iris cysts were identified in a 10 year period study at a ophthalmologic reference Center in Mexico City. The variables included demographic data, ocular and medical history, clinical course, and complications. All patients were examined by UBM, and type, number, location, and acoustic characteristics of cysts were evaluated. Descriptive statistics were performed. RESULTS: Thirteen patients were included (8 men and 5 women). The mean age was 44.5 ± 15.5 years (range 6-70 years). The origin most prevalent was neuroepithelial (92.3%), and 7.7% had stromal cysts. Regarding to location 76.9% were found in the periphery, and 69.2% between meridians II and VI. All cysts showed a moderate to high reflectivity in the wall. Complications were present in 38.5% of cases (15.4% partial angle closure, 15.4% secondary angle closure glaucoma and 7.7% dyscoria). CONCLUSIONS: Most cysts are derived from iris pigmented epithelium, with a benign course and a minor rate of complications. The UBM is an indispensable tool that allows us to plan more specific and conservative treatments, with less damage to ocular structures and, therefore, better visual prognosis

UNTREATED IRIS MELANOMA COMPLICATED BY HYPHEMA AND UNCONTROLLED GLAUCOMA RESPONSIVE TO IODINE-125 BRACHYTHERAPY.

PURPOSE: To describe a case of iris melanoma for which a patient refused treatment for 15 years, and the complications that resulted. METHODS: Single case report. RESULTS: A 52-year-old white man was evaluated for a suspicious pigmented lesion of the left iris. He was followed closely with serial examinations and ultrasound biomicroscopy, and he refused therapy when the lesion showed growth 15 years after presentation. The patient subsequently developed recurrent hyphema, intraocular pressure up to 55 mmHg, and glaucomatous optic neuropathy. He eventually underwent iodine-125 brachytherapy resulting in tumor regression and improvement of intraocular pressure. CONCLUSION: Untreated iris melanoma can develop complications such as recurrent hyphema and glaucoma with irreversible optic nerve damage. Treatment of slow-growing iris melanoma must be considered to prevent complications.

Hemovítreo secundario a quiste iridociliar / Vitreous hemorrhage secondary to iridociliary cyst

CASO CLÍNICO: Varón de 18 años, presentó un hemovítreo inferior de causa desconocida. Se realizan múltiples pruebas, entre ellas ecografía oftálmica y angiofluoresceingrafía (AFG), no encontrándose justificación al sangrado. Finalmente se decide realizar una biomicroscopía ultrasónica (BMU) donde se aprecia un quiste iridociliar. DISCUSIÓN: Los quistes iridociliares son únicos o múltiples, primarios o secundarios. Los primarios suelen tener carácter benigno, por lo que no requieren tratamiento. Cuando el quiste alcanza un tamaño importante puede producir un iris meseta focal con o sin cierre angular. Nuestro caso describe una complicación inusual que habría que tener en cuenta ante un hemovítreo de origen desconocido

CASE REPORT: An 18-year-old man, presented a lower vitreous hemorrhage of unknown cause. Multiple tests are performed, including Ophthalmic Ultrasound and Fluorescein Angioghaphy (FA), they did not find justification of bleeding. Finally, we decide to do a Biomocroscopía Ultrasonic (UBM) showing an iridociliary cyst. DISCUSSION: The iridociliary cysts are single or multiple, primary or secondary. The primaries are usually benign so, they do not require treatment. When the cyst has a considerable size, it may produce a focal plateau iris with or without angle-closure. Our case reveals an unusual complication that should take notice of when you have an unknown vitreous hemorrhage

Plateau iris secondary to iridociliary cysts.

CASE REPORT: We present a case of plateau iris and glaucoma due to multiple unilateral iridociliary cysts. The patient was treated with iridotomy Nd: YAG laser and 360° iridoplasty, without achieving pressure control. Phacoemulsification improved the hypertension. Dynamic gonioscopy and OCT of the anterior chamber was also performed before and after treatment. DISCUSSION: Iridociliary cysts are a benign condition that can cause iris plateau configuration, and can produce a difficult to treat ocular hypertension. Cystotomy, peripheral iridoplasty, and other treatments have been proposed.
