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

[Necrosis of iris and ciliary body--a histopathological study].

Only registered users can translate articles

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

Necrotic melanocytoma of iris with secondary glaucoma.

Only registered users can translate articles

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.

Treatment of iris melanoma with photodynamic therapy.

Only registered users can translate articles

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,

Melanocytomalytic glaucoma in eyes with necrotic iris melanocytoma.

Isoexpansile sulfur hexafluoride gas to repair near-total iris disinsertion.

Only registered users can translate articles

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

Provoked iris ischaemia in the rabbit: A fluorescien angiographic study.

Only registered users can translate articles

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

Lisianthus Leaf Necrosis: A New Disease of Lisianthus Caused by Iris yellow spot virus.

Only registered users can translate articles

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

Cell adhesion molecule expression in cultured human iris endothelial cells.

Only registered users can translate articles

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

Provoked iris ischaemia in the rabbit. I. Clinical and histopathological examinations.

Only registered users can translate articles

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
