Diffuse malignant melanoma of iris with metastases.

A 66-year-old man had decreased visual acuity in the left eye. Slit-lamp examination showed hyperpigmentation of the periphery of the iris from 2:30 to 9 o'clock. Gonioscopy disclosed an ill-defined mass involving the angle and extending from 5 to 7:30 o'clock with diffuse pigmentation of the meshwork for 360 degrees. A sector iridectomy was performed inferiorly in his left eye. Histopathologic examination disclosed a diffuse malignant melanoma of the iris, mixed cell type. The patient was free of recurrence when examined at 18, 24 and 30 months following surgery. Two years and ten months following the iridectomy, the patient developed multiple metastatic bony lesions and a mass in the liver. Bone marrow aspiration from the sternum and biopsy from the iliac crest, respectively, showed metastatic malignant melanoma. He died shortly thereafter and an autopsy was not performed. The remote possibility of an occult, intraocular tumor such as a ciliary body melanoma or an internally located melanoma cannot be excluded. Assuming that this is indeed an iris melanoma, as our studies indicate, the rarity of this metastatic iris neoplasm is emphasized by noting that only 37 cases of iris melanomas with presumed metastases have been reported in the literature.

Fundus manifestations of orbital disease and treatment of orbital disease.

Disorders of the orbit can secondarily involve the eye. Although nonspecific, changes which can be noted on funduscopic examination including abnormalities of the retina, choroid, and optic nerve, can be secondary to an underlying orbital process. Awareness of these findings and their association with orbital disease is of great importance to the practicing ophthalmologist, since many orbital disorders are treatable and indeed, some are life-threatening. In addition, treatment of these disorders can potentially result in a variety of ocular complications. An understanding of the potential risks is of the utmost importance in planning treatment of an orbital disease.

Ophthalmologic findings associated with arthrogryposis multiplex congenita: case report and review of the literature.

Arthrogryposis multiplex congenita is a birth defect characterized by multiple joint deformities and sometimes associated with various other congenital anomalies. There have been several reported cases of miscellaneous ocular abnormalities in conjunction with this syndrome. We report the first case of congenital ophthalmoplegia as well as juvenile onset glaucoma associated with arthrogryposis multiplex congenita. This case represented a unique therapeutic dilemma in that it was extremely difficult to surgically treat the patient's glaucoma because of her severe restrictions of ocular motility.

Optic nerve coloboma with cyst: a case report and review.

A 7-month-old boy presented with strabismus and proptosis of the left eye. He was found to have bilateral optic nerve colobomas associated with cysts arising from the optic nerve sheath and in communication with the subarachnoid space. The evaluation and management of this entity are discussed.

Congenital retinal disinsertion syndrome.

The congenital retinal disinsertion (CRD) syndrome refers to cases of retinal detachment with disinsertion and may be divided into two groups. Group 1 reported by Hovland and co-workers includes healthy children with bilateral detachments and giant tears nasally, lens coloboma, and center anterior and posterior cortical lens opacities. Group 2 includes healthy children with a unilateral detachment often associated with microphthalmos and catatract. The opposite eye may show a combination of changes including small central anterior and posterior cortical lens opacities, lens colobomas, and paving-stone degeneration. The patients may have an increased risk of developing a detachment in the second eye, and some of these eyes have been treated with cryopexy. Seven patients belonging to group 2 have been described and four of these had unilateral cataract and microphthalmos. Two other patients had some degree of unilateral microphthalmos. Small central anterior or posterior cortical lens opacities were found in five eyes, and lens colobomas were found in two eyes. Six out of seven patients had varying degrees of paving-stone degeneration temporally in the nondetached eye. The CRD syndrome was familial in two patients who were sisters. Pathologic studies were done in the eyes of three patients.
