Objective

Synthesis of KYNA in the retina end its presence in the vitreous is well described. Moreover, alterations of KYNA synthesis in the retina in animal models of retinal degeneration have been reported. This study is the first to investigate changes of vitreous KYNA levels in patients with retinal detachment.

Methods

Vitreous fluid samples were obtained at the time of vitreoretinal surgery from 14 patients with retinal detachment. Vitreous samples obtained during surgery from 7 patients with macular holes were used as control. Total KYNA concentrations were measured with HPLC according to the method of Turski and colleagues.

Results

KYNA concentration in the vitreous of patients with retinal detachment reached the level of 2.5±0.34 pmol/ml and was significantly higher as compared to the control group (1.3±0.27 pmol/ml).

Conclusions

KYNA concentrations are increased in the vitreous of patients with retinal detachment. Enhanced endogenous KYNA synthesis might be involved in the pathomechanisms of hypoxic/ischemic insult of the outer retina.
