    […] and iris atrophy.[grantome.com] Iris transillumination.[glaucoma.net] About 30 percent of patients with pigment dispersion syndrome develop pigmentary glaucoma, a type of open-angle glaucoma, according to the Glaucoma Research Foundation.[medical-dictionary.thefreedictionary.com]

  • Pseudoexfoliation Syndrome

    Peripapillary atrophy and iris sphincter region transillumination Melanin dispersion associated with pupillary dilation Poor mydriasis, asymmetric pupil sizes Melanin dispersion[optometricmanagement.com] Loss of iris pigment and its deposition throughout the anterior segment are refl ected in iris sphincter region transillumination defects, loss of the pupillary ruff, pigment[tmj.ro] Pseudoexfoliative glaucoma is a type of secondary glaucoma with a more aggressive course.[jcor.in]

  • Exfoliation Syndrome

    The melanin dispersion is from atrophy of the iris pigment epithelium. Actual pseudoexfoliative material may be noted on the TM.[eyewiki.aao.org] Furthermore, prominent concentric, circular iris transillumination (grade 3) was only observed in XFS.[ncbi.nlm.nih.gov] Other clinical signs associated with exfoliation syndrome are pigment dispersion, transillumination defects of the iris and reduced response to mydriatics.[ncbi.nlm.nih.gov]

Google Scholar Medline ISI 19.[journals.sagepub.com] Clinically the iris would show hypopigmentation without transillumination defects. B. Iris pigment epithelial atrophy in diabetes mellitus.[entokey.com] RESULTS: Infrared transillumination imaging showed extensive atrophy of the iris stroma and occasional pigment clumps both in the pupillary and ciliary zones of the iris,[ncbi.nlm.nih.gov]

  • Ocular Albinism

    Other definite findings include lack or absence of stereoacuity, transillumination defects of iris and pendular nystagmus which typically develops in affected males during[symptoma.com] However, on further examination by a specialist the iris turns out to be able to let light through. This is called iris transillumination.[steadyhealth.com] In this study, eight of ten black ocular albinos from two kindreds had nonalbinotic, moderately pigmented fundi and no transillumination of the iris.[jamanetwork.com]
