291 Possible Causes for Melanin Dispersion in Iris, Poor Mydriasis, 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] Lens capsule atrophy in combination with poor mydriasis can make for challenging cataract surgery in PXS patients. 2,4 While the combination of IOP-lowering medications and[reviewofophthalmology.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] mydriasis, which is also a typical finding in the PXS a fibrillar layer similar to pseudoexfoliation material It may antedate the appearance of PXF by several years.[slideshare.net]

    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]
