iris/necrosis

A 34-year-old man in good general health became bilaterally totally blind by an unusual retinochoroidal degenerative disease 3 years after the initial onset of visual symptoms. The advanced stages of the retinochoroidal disease were associated with bilateral progressive iris necrosis and severe

Antiretroviral therapy (ART) initiation in HIV-infected patients leads to recovery of CD4+T cell numbers and restoration of protective immune responses against a wide variety of pathogens, resulting in reduction in the frequency of opportunistic infections and prolonged survival. However, in a

Necrotic foci within the iris and ciliary body were present in 104 eyes examined at the histopathological laboratory of the University Eye Clinic, Hamburg. Three different aetiological mechanisms were found: 1) Vascular acute glaucoma, diminished arterial supply, or radiogenic occlusive vasculitis

A 23-year-old white man had a pigmented iris tumor that was not enlarging; it produced satellite iris lesions, diffuse pigmentation of the trabecular meshwork, and secondary glaucoma. Although enucleation was initially recommended, we chose to remove only the primary lesion with a sector iridectomy.

Photodynamic therapy was used to treat four patients with iris melanoma. Hematoporphyrin derivative was used as a sensitizing agent. The tumors were exposed to a total dose of 1.72 x 10(6) J/cm2 of 630-nanometer laser light. The eye of the first patient, enucleated after treatment,

OBJECTIVE Iris melanocytoma, although histologically benign, may undergo spontaneous necrosis with the resultant pigment dispersion causing secondary open-angle glaucoma. The authors describe the clinical findings in three patients with this syndrome and review the current literature. METHODS The

A spiroiridal-type triterpenoid, 28-deacetylbelamcandal (1), was isolated from the rhizomes of Iris tectorum as an active principle that stimulated differentiation of human promyelocytic leukemia (HL-60) cells, a short-term screening method for 12-O-tetradecanoylphorbol 13-acetate (TPA)-type tumor

Iridodialysis is commonly encountered after blunt trauma to the eye. Most iris detachments are small, superior, and asymptomatic and require no surgical intervention. However, large areas of iridodialysis require early surgical repair to prevent the onset of iris necrosis, pigment dispersion, and

We studied experimental anterior segment ischaemia in rabbits by fluorescein angiography of the iris. Nine rabbits were subjected to diathermy occlusion of one or both long posterior ciliary arteries or to disinsertion and reattachment of up to 4 rectus muscles. Occlusion of one LPCA or up to 3

Unusual viral symptoms were seen on lisianthus (Eustoma russellianum) grown in the Besor area in Israel. Symptoms included necrotic spots and rings on leaves and systemic necrosis. Preliminary analyses suggested that the disease was caused by a tospovirus. Virus particles typical of a tospovirus

OBJECTIVE To develop a method to isolate human iris microvascular endothelial cells (HIECs) for exploring their constitutive and inflammatory agent-modulated expression of intercellular adhesion molecules (ICAM)-1 and -2, vascular cell adhesion molecule (VCAM)-1, and E-selectin. METHODS Endothelial

Various surgical procedures were performed on albino rabbits, which impaired anterior segment blood circulation. Our early and late clinical observations showed a consequent development of anterior-segment ischaemia into anterior-segment necrosis. The significance of different surgical procedures
