Estimation of Sodium(Na+) and Potassium(K+) in Vitreous Humour of Eye After Death

The interval between death and time of examination of body is called post mortem interval (PMI). The most important medico legal issues in any post mortem examination are to determine time since death (TSD). In present study sodium and potassium of vitreous humour of post mortem cases evaluated within 5 To 48 hours of time since death and serum of antimortem subjects. Vitreous humour sodium concentration decreased and raised of potassium concentration time since death. Resultswere statistically correlated between post-mortem cases and antimortem sodium and potassium value. There was a linear relationship between vitreous humour potassium concentration and post mortem interval (12 hours and u003e 13 hours) and showed significant correlation of potassium and ( p u003c 0.001) and sodium ( p u003c 0.05).
