Some inorganic constituents of the subretinal fluid.

The inorganic constituents of the subretinal fluid (SRF) were analyzed using atomic absorption spectrometry. Four main elements (Na, K, Ca, Mg) were determined in 41 samples; Cu was determined in 36 samples and Zn in 24 samples. The results are presented graphically, taking into account the concentrations of each element in the SRF and the number of cases. In 9 cases, the concentrations of the inorganic elements were also determined in blood serum; it was established that the SRF is richer in Mg than blood serum and poorer in the other elements. No correlation was found between the concentration of the inorganic elements in the SRF and the clinical picture of retinal detachment.
