Structures and Functions of the Vitreous Body
The natural vitreous body has a fine structure and complex functions. The imitation of the natural vitreous body by vitreous substitutes is a challenging work for both researchers and ophthalmologists. Gases, silicone oil, heavy silicone oil and hydrogels, particularly the former two vitreous substitutes are clinically widely used with certain complications. Those, however, are not real artific...

متن کاملCarbonic anhydrase in the vitreous body.
REVIEWS of some recent literature concerning the biochemistry of the vitreous body contain no references to the presence of enzymes (Bellows, 1952, 1953; von Sallmann, 1953, 1954; McLean, 1954). However, the possibility of the existence of enzymes in the vitreous body has not been overlooked. Lepine (1870) reported that the vitreous of dogs, rabbits, and frogs contained a substance which caused...
متن کاملThe importance of qualitative vitreous examination in patients with acute posterior vitreous detachment.
OBJECTIVE To determine whether patients with acute posterior vitreous detachment with pigmented vitreous granules or hemorrhage have a higher likelihood of retinal tear compared with those with qualitatively normal vitreous examination findings. METHODS A multicenter cross-sectional study was performed in 3 peripheral ophthalmic clinics. Patients with acute posterior vitreous detachment were ...
