  • Subacute Sclerosing Panencephalitis

    Gross view of the right eye showing patchy iris atrophy near the pupillary border. The clinical diagnosis prior to autopsy was SSPE.[] Near the pupillary border, patchy iris atrophy could be seen Fig. 3). Patches of depigmentation were present also in the corona ciliaris and pars plana.[]

  • Uveitis

    , anterior and/or vitreous cells, granulomatous or non-granulomatous KPs, focal or diffuse patchy iris atrophy, and elevated intraocular pressure.[] For example, some other Herpesviridae uveitis symptoms include lowered corneal sensation, iris transillumination defects, posterior iris synechiae, unexplained corneal scarring[]

  • MELAS Syndrome

    […] involvement, and patchy atrophy of the iris stroma.[] The main clinical ophthalmologic features were bilateral ptosis, chronic external ophthalmoplegia, diffuse choroidal atrophy, atypical pigmentary retinopathy with macular[]

  • Anterior Uveitis

    Although patchy iris atrophy may be present following an episode of HSV keratouveitis or iritis, inflammatory iris lesions are not typically seen.[] , sectoral, or diffuse iris atrophy, which may distort the pupil and which is best seen on transillumination. 6,9,10,16–18 The acute increase in intraocular pressure has been[] […] active keratitis. 4,13 Posterior synechiae are common. 4,13 Many patients also have decreased corneal sensation, 14 an acute rise in the intraocular pressure, 6,7,14,15 or patchy[]

  • Iris Atrophy

    The commonest form of iris atrophy affected the inner third of the iris stroma in a patchy manner, often with sparing above.[] The red fundus reflex may be seen through the patchy areas of iris atrophy.[] Conventional transpupillary transillumination using white light showed only minute patchy atrophy of the pigment epithelium in the pupillary zone.[]

  • Corneal Blood Staining

  • Congenital Microcoria

    The red fundus reflex may be seen through the patchy areas of iris atrophy.[] The iris stroma is preserved with patchy atrophy of the iris pigment epithelium ( arrows ), which would clinically correspond to a transillumination defect. C.[] Clinically the iris would show hypopigmentation without transillumination defects. B. Iris pigment epithelial atrophy in diabetes mellitus.[]

  • Fuchs' Heterochromic Iridocyclitis

    Risk Factors None known General Pathology The iris shows a decrease in the number of stromal melanocytes with patchy depigmentation of the posterior layer.[] The ciliary body shows stromal fibrosis with muscular atrophy.[] Other associated diseases include ocular trauma, retinitis pigmentosa, Horner syndrome, Status disraphicus and hemifacial atrophy aka Parry-Romberg syndrome.[]
