FIG. 1.

Comparison between retinitis pigmentosa (RP) patients and controls in carbonyl content of proteins in aqueous and serum. Aqueous samples from nine RP and nine control patients were assayed for protein carbonyl content and total protein. Control patients had macular pucker or macular hole, but no other eye diseases. Serum samples from eight RP and seven control patients were also assayed. Each bar represents the mean (±standard deviation) carbonyl content per mg total protein and statistical comparisons were made with Student's unpaired t-test. NS, not significant.
