329 Possible Causes for Melanin Dispersion in Iris, Syneresis, Transillumination of the Iris

  • 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] Signs Radial perivascular retinal degeneration in Stickler syndrome The most common ocular findings in Stickler syndrome are vitreous syneresis in a membranous or beaded configuration[eyewiki.aao.org]

  • 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]

    Iris transillumination defects and apposition of the optic and iris were found. The patient was diagnosed with Uveitis-Glaucoma-Hyphema (UGH) Syndrome.[ncbi.nlm.nih.gov] […] slight non-granulomatous uveitis associated with foreign-body reaction to the lens implant and its supporting iris suture, absence of the anterior vitreous face, advanced syneresis[link.springer.com] Iris transillumination defects and apposition of the nasal haptic and ciliary body were found.
