Clinical Features and Course of Ocular Toxocariasis in Adults (original) (raw)
Figure 5
Continuous (A–D) and discontinuous (E–H) migration of Toxocara granuloma.
(A) The granuloma shape is horizontally long, and the larva lies at the same level as the macula at the time of diagnosis. (B) Gradual inferior granuloma migration is observed. (C) The granuloma has turned toward the inferonasal side. The dotted line denotes a reference line connecting the fovea and inferior optic disc margin. (D) Retinal nerve fiber layer defect (double arrow) remains along the granuloma migration path 41 months after diagnosis. (E) Peripapillary granuloma with macular hard exudate. (F) Four months later, a new granuloma appears along the superotemporal arcade and a tractional membrane extends from the granuloma to the superotemporal vascular arcade and to the inferotemporal retina. A tractional membrane is also noted around the macula. (G) One month later, 2 novel granulomas appear in the macula and inferotemporal retina. (H) Ten months later, the inferior granuloma disappears and the macular granuloma is decreased in size, but multiple retinal nerve fiber layer defects remain (arrows).
