222 Possible Causes for Transillumination of the Iris

  • Isolated Ectopia Lentis

    Transscleral indirect transillumination of the iris did not show any iris pigment epithelial defects.[ijo.in] transillumination, poor pupillary dilatation, persistent pupillary membranes, iridohyaloid adhesions, and prominent iris processes in the anterior chamber angle.[jhu.pure.elsevier.com] There were no areas of iris atrophy, pupillary abnormalities, or iris transillumination in any of the 18 patients examined or their relatives.[cags.org.ae]

  • Ectopia Lentis

    Those patients with simple lens ectopia as well as those with ectopic lenses and pupils had striking transillumination of the iris periphery.[ncbi.nlm.nih.gov] The association between ectopia lentis et pupillae and transillumination of the iris is well documented in the literature, but it has never been reported with skin hypopigmentation[ncbi.nlm.nih.gov] transillumination, poor pupillary dilatation, persistent pupillary membranes, iridohyaloid adhesions, and prominent iris processes in the anterior chamber angle.[jhu.pure.elsevier.com]

  • Exfoliation Syndrome

    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] PURPOSE: Human eyes with exfoliation syndrome (XFS) exhibit a distinctive pattern of iris transillumination defects that are recapitulated in Lyst mutant mice carrying the[ncbi.nlm.nih.gov]

  • Iris Atrophy

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]

  • Pseudoexfoliation Syndrome

    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] On retroillumination, the iris shows peripupillary iris transillumination. The condition is usually bilateral.[mrcophth.com] ASSOCIATED FEATURES • Iris transillumination defects in peripupillary region. • Reduced pharmacological dilatation. • Weakened zonular attachments with lens instability and[medtextfree.wordpress.com]

  • Foreign Body in the Eye

    Examine closely for iris tears and transillumination defects, lens opacities, AC shallowing, and asymmetrically low IOP in the involved eye.[lifeinthefastlane.com] Distortion of the cornea, anterior chamber, iris, pupil or lens indicates ocular penetration. Handy tips: Remember to evert the eyelids in the quest for foreign bodies.[lifeinthefastlane.com]

  • 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]

  • Lynch Syndrome

    Although Fuchs' heterochromic iridocyclitis (FHI) is on the differential for recurrent unilateral inflammatory glaucoma, there was no iris heterochromia, iris transillumination[webeye.ophth.uiowa.edu]

  • Oculocutaneous Albinism
