Table 1 shows the various ocular disorders found in the patients. Mean viral load copies differed significantly between participants who manifested various ocular disorders (F = 362.7, p < 0.001) where CMV retinitis was associated with the highest viral load copies. However, the mean differences of CD4 counts did not differ significantly between the different ocular disorders (F = 2.5, p = 0.20).  Table 2 shows a comparison of mean CD4 counts/viral loads between various ocular disorders manifested. The gene discussed is CD4; the disease is cytomegalovirus retinitis.
