Iris melanoma in a cat : a case report and controversy
Goldberg, Katherine J.
Hobbes presented to Cornell on 9/18/03 for a recheck examination of iris pigmentation OS which had first appeared one year prior. The pigmentation was examined by both the RDVM and a veterinary ophthalmologist in March, 2003 and again in June, 2003. No change in size or appearance was noted between March & June. Between 6/03 and presentation to Cornell in 9/03, a significant increase in the amount of iris pigmentation was evident. No signs of systemic illness were noted. Ophthalmic examination on 9/18/03 revealed all ocular function within normal limits, with moderate increase in iris pigmentation OS since 6/6/03. The new pigmentation was particularly prominent in the termporal region and appeared similar to the original pigmented areas. The newest pigmentation lay flat against the iris; slit lamp examination revealed no irregularities extending into the anterior chamber. Pigmentation in the medial aspect of the iris (old pigmentation) was thicker and slightly raised from the surface. In room light, the structure of the pupil did not seem distorted, but very mildly diminished pupillary constriction was noted in the pigmented eye (OS) when examined in a bright light. This alteration in pupillary function, prior to presentatin suggested that something other than serial monitoring should be done. Hobbs was admitted for diode laser ablation (photocoagulation) of the abnormal pigmentation.
