[Uric acid level in human aqueous and vitreous humor]

Uric acid--a potent endogenous antioxidant--may play a certain role in some eye diseases. However, its content in intraocular humors has not been examined so far. Samples of aqueous and vitreous humor were collected from 32 dead persons for examination. Uric acid was marked by indirect method with uricase. Uric acid level in aqueous humor ranges from 166.67 to 446.4 mumol/l (mean 309.34), whereas in vitreous humor from 77.38 to 452.00 mumol/l (mean 220.80).
