Nine eyes of five cynomolgus monkeys were perfused through the anterior chamber with cationized ferritin (CF) at normal and increased intraocular pressure. After perfusion with glutaraldehyde, the morphologic appearance of the endothelial lining of Schlemm's canal (SC) and of the adjacent regions was analyzed using tangential and sagittal serial sections.(More)
The age-related changes of the ciliary muscle of human eyes (33-87 years) were studied on histological meridional sections. Eighty-five melanoma eyes and 10 eyes of normal donors were investigated. The total area and the length of the muscle, the area of the three main portions and the distance of the inner apex of the muscle to the scleral spur were(More)

Scanning electron microscopic studies of the zonular apparatus in 10 human and 17 monkey eyes revealed two functionally different sets of zonular fibers: the "main fiber" and the "tension fiber" system. The two systems are connected, forming a broad, sagittally oriented "zonular plexus" within the pars plicata of the ciliary body. The zonular plexus is(More)
The authors studied the posterior attachment of the ciliary muscle in seven young (3-10 yr) and five old (26-34 yr) rhesus monkeys by light microscopy and electron microscopy. Posterior attachment of the muscle bundles consisted of elastic tendons, exclusively. The elastic tendons were continuous with the elastic lamina of Bruch's membrane and were also(More)
The composition of the extracellular material of the cribriform meshwork was compared in five normal and 13 glaucomatous eyes of the same age group (58 to 70 years). Enzymatic digestion and histochemical methods applicable to electron microscopy were used. In both groups of eyes the ground substance was sensitive to chondroitinase ABC, and also the other(More)
Electron microscopic serial sections in a tangential plane through the inner wall of Schlemm's canal and the trabecular meshwork in normal and glaucomatous eyes revealed a characteristic network of elastic-like fibers (cribriform plexus), which is directly connected to the inner wall endothelium by a special fiber system (connecting fibrils). This(More)
The scleral spur in 37 human (age 17-87 years) and six cynomolgus monkey eyes (2-4 years) was investigated. Serial meridional and tangential sections were studied with ultrastructural and immunocytochemical methods. The bundles of the ciliary muscle do not enter the scleral spur, but their tendons, which consist of elastic fibres join the elastic fibres in(More)
Postnatal development of the neuro- and viscerocranium with special reference to the maxillodental structures was studied morphometrically by analyzing computer tomograms and radiograms of human and monkey heads of different age groups. The following parameters were used: the prognathic angle, the clivus angle, the palate-incisivus angle, the interincisival(More)
The relationship between individual ciliary muscle cells and the surrounding connective tissue was studied in the eyes of three normal, young (3-4 years) cynomolgus monkeys (Macaca fascicularis), three aged (34-36 years) rhesus monkeys (Macaca mulatta) and seven young (3-7 years) cynomolgus monkeys topically treated with prostaglandin F2 alpha (PGF2 alpha)(More)
