469 Possible Causes for Fundoscopy Abnormal, Melanin Dispersion in Iris, Transillumination of the Iris

  • 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]

  • 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]

ERG is the most useful tool in assessing function.[patient.info] The classic triad of PPDS is the presence of Krukenberg spindles (KS), transillumination iris defects (TID), and trabecular pigmentation.
