• mutants develop iris disease that is first noticeable at 6 months of age when a population of small phagocytic clump cells began to be discernible across the iris surface
• with age, the underlying vasculature becomes obscured, and irides appear increasingly coarse and atrophic, particularly at the pupil margin where a narrow white band of underlying tissue is exposed
• with advanced age, full-thickness iris holes occur, but rarely before 2 years of age
• irises are normal at 1-6 months of age, however, after 6 months of age, eyes show a gradual atrophy of the iris stroma

GpnmbR150X/GpnmbR150X Tyrp1b/Tyrp1b mice develop a severe iris disease

vision/eye
• double mutants develop iris disease that is first noticeable by 6 months of age, when all eyes show slight swelling of peripupillary tissue
• at 12, 14, and 18 months of age, increasing degree of iris atrophy is observed, that includes full-thickness iris holes, profound transillumination, pigment dispersion and frequent pigment accumulation on the lens and cornea, and changes to the dimensions of the anterior chamber
• however, mutants do not develop glaucomatus nerve damage that is seen in DBA/2J mice
• severe pigment dispersing iris disease
• timing and severity of pigment dispersing iris disease is similar to that seen in either single mutant on a DBA/2J background
• atrophy is seen by 6-9 months of age
• double mutants are less susceptible to intraocular pressure elevation than DBA/2J mice
