case_images: Case 1. A 67-year-old woman with vitreous opacity and atrophic optic disc
  in the right eye (B, left panel) and the left eye (B, right panel).
  Vitreous cytology of vitrectomy fluid in both eyes demonstrates
  medium-sized cells with aberrant nuclei in hematoxylin-eosin stain (A),
  which is positive for CD3 (C), indicative of T-cells. Bar = 50 microm.

case_images: Vitreous opacity in both eyes prevented detailed fundus visualization, but the optic discs in both eyes appeared atrophic (Figure 1B). On cytological examinations, the vitreous aspirates contained medium-sized cells with aberrant nuclei (Figure 1A). Immunostaining revealed that these cells were positive for CD3, indicative of T-cells (Figure 1C).

case_images: Case 2. A 39-year-old man with aqueous pseudohypopyon in the right eye
  (arrowhead, B). Cytology of aqueous tap demonstrates class V abnormal
  cells with flower-like convoluted nuclei in Papanicolaou stain (A). Bar
  = 50 microm.

case_images: Four months after HSCT, he noticed blurred vision in the right eye and showed aqueous hypopyon in the right eye (Figure 2B). Cytological examination of aqueous tap showed atypical cells with Class V (Figure 2A).
