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.

Diode laser transscleral cyclophotocoagulation in the treatment of refractory glaucoma with iris melanocytoma.

Iris melanocytoma is a rare melanocytic nevus with distinctive clinical and pathologic features. Secondary glaucoma may develop rapidly and respond poorly to glaucoma medication in some cases. However, few data are available in the literature with respect to the appropriate treatment for refractory glaucoma associated with iris melanocytoma. Herein, we present a 28-year-old man with blurred vision and an elevated intraocular pressure (IOP) of 40 mmHg in his right eye while on multiple glaucoma medications. A dark brown lobulated iris mass with surrounding small pigmented lesions was noted between the 4 and 5:30 o'clock positions. Sector iridectomy was performed and pathologic examination revealed an iris melanocytoma. After surgery, antiglaucomatous medications still failed to control IOP. The patient then underwent diode laser transscleral cyclophotocoagulation (TSCP). At the last follow-up of 15 months, IOP had returned to normal without the need for medication.

[Intraocular hemorrhage in a goat with thrombocytopenia and metastasis of an adenocarcinoma in the iris]. / Intraokuläre Blutung bei einer Ziege mit Thrombozytopenie und Karzinommetastase in der Iris.

This case report describes the findings in a 10-year-old goat with metastasis of an adenocarcinoma in the iris. Two weeks before admission, the owner had noticed blepharospasm of the left eye. Clinical examination by the referring veterinarian revealed unilateral intraocular hemorrhage. The goat was referred to our clinic for further work-up. The rectal temperature was 40 degrees C. The most important haematological result was severe thrombocytopenia. There was mild corneal oedema of the left eye. Approximately 75 per cent of the anterior chamber was filled with non-coagulated blood. The fluid in the anterior chamber dorsal to the blood was cloudy, and the corpora nigra could not be seen clearly. All other internal parts of the eye could not be seen. Ultrasonography of the left eye confirmed cloudiness of the anterior chamber and revealed moderate thickening of the iris. The right prescapular lymph node was markedly enlarged. Cytological examination of a fine needle aspirate of the lymph node showed a mixed population of neoplastic cells. Based on immunohistochemical evaluation of the cells metastasis of a carcinoma was diagnosed. The goat was subjected to euthanasia, and a postmortem examination was carried out. The anterior chamber of the left eye contained blood, and the iris was thicker than normal and adhered to the posterior surface of the cornea. There were neoplastic alterations in the iris, the oesophagus, the lung lobes, the liver, the kidney and in the prescapular, retropharyngeal, mediastinal and hepatic lymph nodes. Histologically, a diagnosis of carcinoma was confirmed, but the origin of the tumour could not be determined.

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.

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.

The best of the best: a review of select pediatric ophthalmology and strabismus case reports published in 2015.

This review highlights 4 case reports in the field of pediatric ophthalmology and strabismus published in the year 2015. The first article describes ocular presentations of acute childhood leukemia relapse. The second demonstrates the association of sector iris hemangioma with diffuse choroidal hemangioma. The third article provides a secondary procedure for persistent hypertropia in thyroid-related orbitopathy, and the fourth article describes a treatment for cyclic esotropia with temporary use of prismatic correction.

Primary choroidal melanoma in phakomatosis pigmentovascularis IIa.

PURPOSE: To describe a previously unreported association between phakomatosis pigmentovascularis (PPV) IIa and primary choroidal melanoma. DESIGN: Case series. PARTICIPANTS: Three patients with PPV type IIa and choroidal melanoma. RESULTS: Nevus flammeus was present unilaterally in each patient, involving the hemiface, the hemithorax, or both. Ocular melanocytosis also was present unilaterally in all patients involving the sclera, the iris, the choroid, the distribution of the trigeminal nerve, or a combination thereof. Renal cysts were noted in patient 1, and a nevus anemicus of the neck was noted in patient 3. A unilateral choroidal melanoma was detected in each of these 3 patients, in each patient involving the same eye in which melanocytosis had been seen. No metastases were found in any patient. CONCLUSIONS: Clinicians should be aware of the possibility that PPV, and in particular that occurring in patients with ocular melanocytosis, can be associated with choroidal melanoma.

Management of prominent iris vascular tufts causing recurrent spontaneous hyphema.

PURPOSE: To report the management of recurrent, spontaneous hyphema associated with florid iris vascular tufts in a patient presenting for cataract surgery. METHODS: Interventional case report and review of the literature; presentation of clinical findings, iris angiography, and the argon laser regimen used to minimize potential corneal complications with increased total treatment energy. RESULTS: An 80-year-old man with a 20-year history of bilateral, recurrent, spontaneous hyphema associated with extensive iris vascular tufts presented with visually significant cataracts. Serial argon laser photocoagulation treatment of the prominent, circumferential iris vascular tufts of the left eye arrested further episodes of spontaneous hyphema and facilitated uneventful cataract surgery. Argon laser parameters were titrated to therapeutic effect during the initial treatment sessions, and sectoral photocoagulation of the circumferential vascular tufts was performed during a 5-month period to accommodate increased laser power and energy. The total energy required to complete treatment of the extensive lesions was substantially more than that in similar previous reports; however, no adverse corneal complications were associated with the laser therapy. CONCLUSIONS: This case appears to represent the first description of chronic, bilateral, recurrent spontaneous hyphema associated with iris vascular tufts. Argon laser treatment of symptomatic iris vascular tufts promotes resolution of recurrent, spontaneous hyphema and may serve to mitigate the risk of hemorrhage from these lesions during subsequent intraocular surgery. Conservative management of increased total treatment energy may minimize the potential risk of corneal decompensation with argon laser therapy.

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.

Melanocytoma of the iris with rapidly developing secondary glaucoma.

A 28-year-old woman with an upper nasal iris mass developed secondary glaucoma within a few months of presentation. Although the elevated pressure responded to medical therapy, in the interests of a definitive diagnosis as well as prevention of damage to the trabecular meshwork, surgical management was decided upon. Tumor excision was performed through a double-layered sclerolimbal flap. Light and electron microscopic examinations of the tissue revealed a partially necrotic iris melanocytoma. Six months after surgery, the patient's best corrected visual acuity was 20/30 in the affected eye, and the intraocular pressure was 21 mmHg without therapy. The lens remained clear. The differential diagnosis and management of melanocytomas, particularly the role of biopsy, are discussed.

7diffuse melanotic lesion of the iris as a presenting feature of ciliary body melanocytoma: report of a case and review of the literature.

Melanocytoma of the ciliary body is quite rare. Although the tumor is benign, it can spread to the surrounding structures, causing glaucoma and giving an erroneous impression of melanoma. We report a case of melanocytoma of the ciliary body in a 19-year-old woman who presented with diffuse melanocytic proliferation of the iris with uncontrolled secondary glaucoma and a subconjunctival pigmented mass. Fine-needle aspiration of the iris lesion and a histopathologic study of the subconjunctival mass could not rule out melanoma. Enucleation of the painful glaucomatous eye showed evidence of ciliary body melanocytoma with extension into the angle structures as well as the subconjunctival tissue.

Iris melanoma in a patient with neurofibromatosis.

Neurofibromatosis type 1 (NF1) is a common autosomal dominant hamartomatous disorder, which is considered to be a neurocristopathy. Uveal melanoma, also of neural crest origin, is the most common primary malignant intraocular tumor in adults. The association of NF1 and uveal melanoma is controversial. We present a clinicopathologic report of iris melanoma in a patient with NF1 and review the literature for a possible causal association. To our knowledge, only 18 cases of uveal melanoma, including three cases of iris melanoma, have been reported in association with NF1. On the basis of the prevalence of NF1 (1 in 3000) and the prevalence of uveal melanoma (1 in 13,500), it can be estimated that approximately seven patients with NF1 in the United States would have an associated uveal melanoma by chance alone. We conclude that despite the theoretical possibility of a causal association of uveal melanoma and NF1, it may still be regarded as coincidental in the absence of any strong evidence to the contrary.

Aggressive nevus of the iris with secondary glaucoma in a child.

PURPOSE/METHODS: We studied a case of an aggressive iris nevus that caused secondary glaucoma in a child. RESULTS/CONCLUSION: Unlike most iris tumors, this tumor grew from the superior aspect of the iris. The nevus was also unusual because it invaded the trabecular meshwork and caused secondary glaucoma.

A case of primary B-cell type non-Hodgkin lymphoma originating in the iris.

PURPOSE: To report a case of primary malignant B-cell type non-Hodgkin lymphoma originating in the iris. DESIGN: Interventional case report. METHODS: An 83-year-old woman presented with anterior uveitis resulting from primary malignant lymphoma in the iris. Ultrasound biomicroscopy and indocyanine green angiography using a scanning laser ophthalmoscope showed abnormalities in the iris. Diagnostic biopsy of the iris revealed B-cell type non-Hodgkin lymphoma. RESULT: The patient was treated with radiotherapy, and the tumorous lesion resolved. CONCLUSION: Primary lymphoma localized in the iris only is rare. In this case, diagnostic biopsy and radiotherapy of the iris lymphoma provided good results.
