Figure 1: Ultrawide-field fundus photograph of the left eye showing premacular hemorrhage (Valsalva retinopathy). The bleed has a zonal distribution. Central haze is artifact because of posterior subcapsular cataractA 27-year-old otherwise healthy male developed Valsalva retinopathy in his left eye after an episode of vomiting and presented with premacular bleed (sudden vision loss). The corresponding subhyaloid space had three zones – uppermost zone of clear plasma, middle zone of denatured hemoglobin (yellow band), and lower zone of sedimented red blood cells Fig. 1. The figure clearly elicits the density of denatured cells being less than sedimented cells, thus floating on the latter and forming a dual layer in a closed subhyaloid space.
