Chemical composition features of vitreous in terminal glaucoma and hypertensive pain syndrome

: In patients with terminal glaucoma and hypertensive pain syndrome urea concentration in vitreous was 3,8-46,8 mmol/l and creatinine concentration was 0,036 - 0,126 mmol/l. Obtained values are comparable with those in blood serum and correlate with intensity of pain in damaged eye. Pain origin was found to be associated with elevation of urea concentration in vitreous compared with that in blood. It is proposed that urea accumulation in vitreous is one of significant factors of ocular pressure elevation in terminal glaucoma.
