The Retinal Vessels

American Journal of Ophthalmology, 1965
This text, translated from German, attempts to correlate the clinical appearance and histologic changes in retinal vascular disease. In ophthalmology this goal is always sought but rarely achieved. The author is to be congratulated for embarking upon a study requiring much diligence and patience which can only assist in a better understanding of the ...

The ultrastructure of the retinal vessels

Journal of Ultrastructure Research, 1963
Three types of cells form the perivascular glia: Muller cells, and two types of astrocytes. The Muller cytoplasm surrounds the major portion of the capillary walls in all layers, with occasional contributions from thn accessory glia. The large arteries and veins are ensheathed by glial cytoplasm derived equally from Muller cells and accessory glia ...

In vivo micropuncture of retinal vessels

Graefe's Archive for Clinical and Experimental Ophthalmology, 1993
Micropuncture has proven to be a valuable tool for the local study of vascular parameters in many organ systems; however, it has not been applied to the study of the circulation of the retina. We report here our extension of micropuncture techniques [4] to use in the intact retina of the anesthetized cat.

Retinal Telangiectasis and Proliferation of the Retinal Vessels in a Family [PDF]

Ophthalmologica, 1993
A 20-year-old woman presented with a marked proliferative retinopathy of the entire central region of the retina in both eyes, with veil-like epiretinal gliovascular membranes and isolated spots of haemorrhaging. The outer region of the retina was unremarkable. Her 49-year-old mother showed perimacular telangiectases in both eyes.

Retinal Vessel Dehydrogenase Enzymes

Archives of Ophthalmology, 1964
The isolation of the retinal vessels by the trypsin digestion technique 1 allows histochemical studies on this structure. Recently, histochemical studies of several enzyme groups, including the dehydrogenase enzymes, have been reported. 2 The present study is a more detailed study of these dehydrogenase enzymes in the rat, cat, and dog with nitro-blue ...

Visualization of Retinal Blood Vessels

2021
The retina offers a unique opportunity to directly visualize blood vessels in vivo noninvasively. Over the past few decades, several new imaging techniques have been adapted to study the retinal vasculature in the laboratory in animal models and in the clinic in human subjects.

RETINAL VESSELS WHITENING IN RETINITIS PIGMENTOSA

Retina
Purpose: To characterize retinal vessel whitening (RVW) in retinitis pigmentosa (RP). Methods: Single-center cross-sectional study. Review of clinical notes of clinically confirmed patients with RP was performed followed by grading ultra-widefield imaging.

In vivo cannulation of retinal vessels

Graefe's Archive for Clinical and Experimental Ophthalmology, 1987
In vivo cannulation of retinal blood vessels has not been reported but would be useful in exploring local vascular parameters and new treatment modalities. We developed a microsurgical technique for cannulating rabbit and cat retinal vessels, using glass micropipettes with curved shanks made from standard capillary tubing.
