Leiomyoma of the Iris, Sprague-Dawley Rat

Part of the Monographs on Pathology of Laboratory Animals book series (LABORATORY)


Because of their small size, intraocular location, and rarity, these tumors have not been seen grossly at necropsy. Subgrossly, they are small mesenchymal tumors confined to and distorting the iris (Fig. 47). It can be envisaged that an ophthalmologic examination would reveal a nodular growth that distorts the iris and the pupil and normal pupillary dilatation with mydriatics would be prevented. A large tumor could impede aqueous outflow, resulting in enlargement of the eye and secondary glaucoma.
