294 Possible Causes for Regional and Ethnic Clustering, Transillumination of the Iris

  • Exfoliation Syndrome

    Furthermore, prominent concentric, circular iris transillumination (grade 3) was only observed in XFS.[] Other clinical signs associated with exfoliation syndrome are pigment dispersion, transillumination defects of the iris and reduced response to mydriatics.[] PURPOSE: Human eyes with exfoliation syndrome (XFS) exhibit a distinctive pattern of iris transillumination defects that are recapitulated in Lyst mutant mice carrying the[]

  • Sicca Syndrome

    Although it is difficult to distinguish between whether the observed variation reflects clustering of risk factors for SLE or regional differences in diagnosis and treatment[] Keratoglobus does not exhibit the ocular signs associated with megalocornea, such as iris stromal hypoplasia with iris transillumination.[] , there is a clear pattern of elevated mortality in clusters with high poverty rates and greater concentrations of ethnic Hispanic patients versus those with lower mortality[]

  • Ectopia Lentis

    Those patients with simple lens ectopia as well as those with ectopic lenses and pupils had striking transillumination of the iris periphery.[] 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[] transillumination, poor pupillary dilatation, persistent pupillary membranes, iridohyaloid adhesions, and prominent iris processes in the anterior chamber angle.[]

    MATERIAL AND METHODS A random cluster sampling population study using a field questionnaire was distributed to 4714 individuals in 6 regions within Inner Mongolia, northern[] China; the study included ethnic Mongol minorities and Chinese Han populations.[]

  • 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[] [Clinical studies of depigmentation of the pupillary margin and transillumination of the iris in cases of senile cataract and also in normal eyes in the aged] [Thesis]. 1917[] On retroillumination, the iris shows peripupillary iris transillumination. The condition is usually bilateral.[]

  • Streptococcus Pyogenes

    Temporal and geographic clustering provides further evidence for “rheumatogenic” strains. Whether ethnic or racially determined factors affect this shift is not known.[] Since 1985, there have been scattered outbreaks of acute rheumatic fever in some regions of the United States.[]

  • Oculocutaneous Albinism

    An African girl with OCA-2 showing iris transillumination, yellowish tinted hair and many solar lentigines.[] As a measure of ocular pigment, iris transillumination and macular transparency were graded according to a previously published scheme.[] 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[]

  • Iris Atrophy

    Infrared transillumination stereophotography of normal iris. Can J Ophthalmol 1977 ; 12: 308 – 11 . Google Scholar Medline ISI 19.[] Clinically the iris would show hypopigmentation without transillumination defects. B. Iris pigment epithelial atrophy in diabetes mellitus.[] 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,[]

  • 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.[] 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.[]

  • 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[] However, on further examination by a specialist the iris turns out to be able to let light through. This is called iris transillumination.[] In this study, eight of ten black ocular albinos from two kindreds had nonalbinotic, moderately pigmented fundi and no transillumination of the iris.[]
