iris/dental caries

BACKGROUND Iris melanocytoma (IM) is a rare benign tumor, but unavoidable in differential diagnosis of pigmented iris lesions. According to the best knowledge of the authors it is for the first time in Serbia that a well-documented case of IM is presented and that the problem of this tumor is

A 56-year-old man presented with a pigmented iris nodule which showed prominent vessels and enlargement within 6 weeks. The tumour caused recurrent hyphemata. Differential diagnosis included a pigmented iris hemangioma and a malignant melanoma. A sectoriridectomy was performed. Histology revealed a

UNASSIGNED To report the association of rubeosis iridis with chronic bullous degenerative peripheral retinoschisis. UNASSIGNED A 63-year-old female presented with acute hyphema and neovascularization of the iris in association with elevated intraocular pressure. Posterior segment examination

OBJECTIVE To describe progressive enlargement of intralesional cavities within a mass that masqueraded clinically as an iris pigment epithelial cyst for 2 years but later proved to be a melanoma. METHODS An 81-year-old woman developed asymptomatic focal elevation of the iris, and ultrasound

We introduce a technique for iris fixation of a posterior chamber intraocular lens (IOL) in which most of the procedure is done outside the eye. This minimizes intraocular manipulation, maximizes corneal endothelial preservation, and avoids the risk for IOL drop into the vitreous cavity

After lentectomy of the adult newt eye, non-dividing iris epithelial cells re-enter the cell cycle. Some of the iris epithelial cells become completely depigmented while they are in the cell cycle, and then differentiate into lens cells. The remaining iris epithelial cells become partially

Ovarian cancer is the first in mortalities among gynecologic cancers in the United States, often due to late diagnosis and/or acquired platinum-resistant recurrences. This study investigates whether BRCA1-IRIS is a novel treatment target for ovarian cancers and in platinum-resistant recurrences.

Phacoemulsification of the lens in eyes with zonular loss risks dislocation of the lens into the vitreous cavity. We describe the use of iris hooks after capsulorhexis to support the lens during surgery. With iris hooks, the lens can be stabilized, helping prevent additional loss of zonules and

OBJECTIVE To describe management of posteriorly retained iris expansion ring-a newly reported complication of phacoemulsification surgery in a patient with intact posterior capsule. METHODS Case report. METHODS A 64-year-old monocular patient with history of regressed proliferative diabetic

Ciliary and iris block glaucoma in aphakic and phakic eyes is characterized by the accumulation of aqueous humor in the vitreous cavity causing an increase in vitreous volume, a flattening of the anterior chamber, and an elevation of intraocular pressure. As vitreous blocks the space between the

Strong selection pressures are known to act on animal coloration. Although many animals vary in eye colour, virtually no research has investigated the functional significance of these colour traits. Passeriformes have a range of iris colours, making them an ideal system to investigate how and why

OBJECTIVE To describe and illustrate the ultrasound biomicroscopic findings in patients with one or more cystic lesions of the iris, ciliary body, or both. METHODS Retrospective study of 263 ultrasound biomicroscopic studies performed at one institution during a 20-month period, May 1994 through

The iris anlage of 3--10 day old chicken embryos was studied by both light and electron microscopy. Serial semithin sections showed that some of the mesenchymal cells overlying the eye cup moved into the primitive eye cavity by the 3rd day of incubation. On the 4th day some of these cells came into
