  		FIG 1. 5-month-old boy with juvenile retinoschisis.

A and B, Axial noncontrast CT scan through the inferior aspect of the orbits shows an area of increased attenuation that appears to be layering along the posterior aspect of the right globe (curved arrow, A) and in the lateral (temporal) aspect of the left globe (curved arrow, B). This was thought to represent blood or other proteinaceous fluid. The nondependent (anterior) surface of this collection is flat and therefore suggestive of a fluid-fluid level (straight arrows).

C and D, B-scan sonograms of the right (C) and left (D) globes. A complex cystic mass in the right globe abuts the retina and contains a fluid-fluid level (arrowheads, A). The high echotexture component of the mass present in the dependent portion (d) probably represents highly proteinaceous fluid or layering blood products and corresponds to the area of increased attenuation seen on the CT scans. The lower echotexture component in the nondependent portion (n) is probably composed of fluid with low protein content (ANT indicates anterior). The B-scan sonogram of the left globe (D) shows a similar but smaller mass (arrowhead indicates fluid-fluid level).
