In 26 of 227 patients with carcinoma metastatic to the eye or orbit, metastasis to the anterior uveal tract was the predominating feature. There was a definite propensity for the tumor to involve the horizontal meridian of the iris or ciliary body, rather than the upper or lower portions. The site of the primary tumor in the 26 patients was as follows: lung 14; breast, 9; kidney, 2; and rectum, 1. Ocular symptoms and signs produced by the metastatic tumors at onset or during the course of the disease included decreased vision (80%), a visible mass (72%), redness of the eye (56%), pain (56%), glaucoma (56%), iridocylitis (44%), and hyphema (24%). The median survival of the 26 patients with metastasis to the anterior segment of the eye was only 5.4 months from the time of ocular surgery. This is poorer than the median survival (7.2 months) of the patients with metastasis confined to the posterior segment, and much worse than the median survival (15.6 months) of the 28 patients with orbital involvement.

This paper is based on 21 patients with metastases of the choroid from extraocular tumors, observed over a period of 25 years (1952--1977) at Erlangen University Eye Clinic. Approximately 70% of these relatively rare metastases of the choroid are caused by cancer of the breast. Ophthalmoscopically, they are usually localized to the left of the posterior pole and are yellowish. In about 20% of the cases both eyes are affected. Since breast cancer is the most frequent cause of the primary tumor, women in the 40 to 60 age group are the most common sufferers. On the other hand, it is worth mentioning that in 2 cases the metastases were the first signs of any type of malignancy. Typical is the relatively flat, shell-like growth. In cytological specimens the portion of the retina covering the tumor normally shows no evidence of cystic degenerative change, in contrast to malignant melanoma. In view of the short average life expectancy of about 9 months, therapy should consist in preserving the eye and thus some degree of vision. Radiotherapy, chemotherapy or cytostatic therapy whould be tried. Enucleation is only indicated where there is severe pain, secondary glaucoma, amaurosis or if it is impossible to differentiate from a malignant melanoma.

Report on a rare case of an iris-ringmelanoma. Arising from the iris base the primary tumor spread in a continuous line along the anterior chamber angle and a shedding of tumor cells in other places of the iris surface could be stated as well. A unilateral dark spotted colouring of the iris with a secondary glaucoma was clinically observed. Gonioscopy, diaphanoscopy, 32P-test, and iris fluorescence-angiography aided the diagnosis. Fluorescence angiography appears to be of particular value in the diagnosis of malignant melanoma of the iris: The peculiar filling pattern seen at the pupillary border of the tumor has up to now only been found in malignant processes of the anterior uvea. The clinical tentative diagnosis of malignant ringmelanoma of the iris, could histopathologically be verified.

We describe a case of cutaneous malignant melanoma metastatic to the iris and the angle 31 months after excision of the primary tumor in a 37-year-old caucasian female patient. The patient who had numerous metastases (lung, liver, cerebrum, skin) suffered from secondary glaucoma and died 5 months after the discovery of the intraocular metastases. The glaucoma was treated with medications and cyclocryotherapy. There was no response of the iris metastases to cyclical combined chemotherapy.

A 52-year-old woman noted loss of vision in August 1984. Clinical examination disclosed iris cysts and ciliary body cysts, macular edema, and uveal nevi. Cataract extraction and pressure-lowering operations were required in both eyes because of a tumor-induced angle-closure glaucoma. Vision, however, progressively decreased to light perception in each eye. Both eyes were finally enucleated because a malignant melanoma could not be ruled out, though iris tissue obtained in 1985 suggested a nevuslike process. Histologic study indicated a bilateral uveal hyperplasia. Results of light and electron microscopy, immunologic studies, and suspension cell culture suggested that the uveal hyperplasia was more likely a melanoma of low malignancy than a nevuslike process. We could not detect an extraocular primary tumor and assumed that this condition constituted an oncogenic syndrome.

Breast carcinoma is the most common primary tumor producing intraocular metastasis. Metastases to the iris and ciliary body are relatively rare. The authors report a case of a 61-year-old lady, operated for carcinoma of the left breast 3 years back, who presented with symptoms and signs of acute narrow-angle glaucoma in the right eye. A diffuse whitish plaque-like mass in the upper nasal quadrant of the iris with an episcleral nodule on the limbus in the corresponding area and all the signs of acute narrow-angle glaucoma were present in the right eye. Intraocular pressure was controlled medically. Fine-needle aspiration cytology from the episcleral nodule showed malignant cells. Histopathology of the excised nodule showed metastatic poorly differentiated carcinoma, and the cellular pattern was similar to the carcinoma of the breast. There was no other metastasis anywhere in the body. Fine-needle aspiration cytology from an external lesion of the eye is a less invasive and easier procedure than paracentesis to diagnose the metastatic nature of the lesions. The rare features in our case are the clinical presentation as acute glaucoma and the ocular structures being the first and only site of metastasis.

Objective: To observe the clinical and pathological features of uveal metastatic carcinoma. Methods: It was a retrospective case series study. The clinical manifestation, growth pattern, tumor types and relative pathological features of 13 patients visiting from January 1980 to December 2014 with uveal metastatic carcinoma in Tianjin Eye Hospital were analyzed retrospectively. Results: There were 13 cases, 6 cases of male and 7 of female. Age was from 37.0 to 66.0 years old. The mean age was 52.1 years old. all cases were monocular. There were 5 cases with right eye and 8 cases with left eye. Among 13 cases, 10 tumors were in posterior choroid, one tumor was in anterior choroid and ciliary body, 2 tumors were in the iris. There were 5 patients with lung cancer, 4 patients with breast cancer, 1 patient with prostate cancer, 1 patient with thyroid cancer and 1 patient with esophageal cancer. The primary tumor wasn't found in 1 patient. The rapid decrease of visual acuity showed in 10 patients with posterior choroidal metastatic carcinoma, 8 of them accompanied with extensive retinal detachment and 6 of them had secondary glaucoma. The multiple gray-white nodule or pink cauliflower mass on the papillary margin of iris were showed respectively in 2 patients with iris metastatic carcinoma. The pathological examination found that posterior choroidal metastatic carcinoma mainly located in temporal or nasal side choroids in 10 cases, among them, local or diffuse flat choroidal masses showed in 6cases, extensive mass involving choroid and ciliary body showed in 1 case, large nodular or globular choroidal mass showed in 2 cases, choroidal mass surrounded the optic disc in 1 case, optic nerve invasion showed in 3 cases and extraocular or orbital invasion showed in 3 cases. The scleral and subconjunctival invasion showed in 1 case of anterior choroid and ciliary body metastatic carcinoma. Conclusions: Uveal metastatic carcinoma manifested various growth pattern, the rapid decrease of visual acuity, flat or nodular choroidal solid mass, secondary retinal detachment and glaucoma were common clinical features. Some cases might invade extraocular or orbital tissue. (Chin J Ophthalmol, 2016, 52: 769-774).
