274 Possible Causes for Alopecia at the Occipital Defect, Melanin Dispersion in Iris, Transillumination of the Iris

  • 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]

  • Knobloch Syndrome Type 1

    […] pigment epithelial cell layer and release of melanin granules that resembled the human pigment dispersion syndrome. 33 Two patients in our series with clinical features of[doi.org] Anterior segment abnormalities included absent iris crypts, iris transillumination, lens subluxation, and cataract.[ncbi.nlm.nih.gov] Absence of iris crypts and a single case of iris atrophy have been described previously. 3 - 5 , 32 In a knockout mouse model COL18a1 / , there was disruption of the posterior iris[jamanetwork.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] Atrophy of the pigment epithelium may be associated with anterior chamber melanin dispersion, which may be seen as a whorl-like pattern of pigment particles on the iris sphincter[slideshare.net]

  • 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]

  • Oculocutaneous Albinism

    An African girl with OCA-2 showing iris transillumination, yellowish tinted hair and many solar lentigines.[clinicaladvisor.com] As a measure of ocular pigment, iris transillumination and macular transparency were graded according to a previously published scheme.[ncbi.nlm.nih.gov] Traditionally, the diagnosis of ocular or oculocutaneous albinism (OCA) is based on a constellation of features including the presence of nystagmus associated with iris transillumination[ncbi.nlm.nih.gov]

    Infrared transillumination stereophotography of normal iris. Can J Ophthalmol 1977 ; 12: 308 – 11 . 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]

    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]
