Figure 2. Array CGH results for keratoconus patients versus controls. Chromosomes shown were chosen randomly as representative of all chromosomes and in all Keratoconus patients tested. A: Chromosome 16 and B: Chromosome 20. When control DNA was hybridized against patient’s DNA, a signal ratio of zero (0) was obtained, indicating the absence of chromosomal copy number alterations.
