777 Possible Causes for Lens Dislocation, 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.[] Furthermore, prominent concentric, circular iris transillumination (grade 3) was only observed in XFS.[] Moreover, exfoliation syndrome may cause cataract or lens dislocation.[]

  • Pseudoexfoliation Syndrome

    Peripapillary atrophy and iris sphincter region transillumination Melanin dispersion associated with pupillary dilation Poor mydriasis, asymmetric pupil sizes Melanin dispersion[] 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[] Spontaneous posterior capsule rupture is a very rare entity and its association with lens-nucleus dislocation even more.[]

  • Ectopia Lentis

    Those patients with simple lens ectopia as well as those with ectopic lenses and pupils had striking transillumination of the iris periphery.[] Dislocated traumatic lens (cataract). Ectopia lentis. Dislocated lens into the vitreous secondary to trauma.[] 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[]

  • Isolated Ectopia Lentis

    Transscleral indirect transillumination of the iris did not show any iris pigment epithelial defects.[] What is lens dislocation?[] transillumination, poor pupillary dilatation, persistent pupillary membranes, iridohyaloid adhesions, and prominent iris processes in the anterior chamber angle.[]

  • Marfan Syndrome

    Iris transillumination defects (ITD) were significantly more common in MFS eyes (odds ratio for MFS in the presence of ITD, 3.7).[] Physical examination revealed a lens dislocation with strabismus, high palate, positive wrist and thumb signs, joint hypermobility, and pes planus.[] When lens dislocation interferes with vision or causes glaucoma, surgery can be performed and an artificial lens implanted.[]

  • Lens Dislocation

    The dislocated lens was replaced with another posterior chamber intraocular lens sutured at the ciliary sulcus.[] Ocular Examination  Iris- iridodonesis, transillumination  Appearance of the pupil  assess the adequacy of the pupillary space for a possible aphakic correction  Lens-[] We report a case of lens dislocation caused by simple vomiting. This case further implicated for the pathogenesis of lens dislocation.[]

    What is lens dislocation?[] transillumination defects, concave iris, increased pigmentation of trabecular meshwork, deposited pigment on Schwalbe's line AD - %600510 PRADER-WILLI SYNDROME Refractive[] transillumination defects, concave iris, increased pigmentation of trabecular meshwork, deposited pigment on Schwalbe’s line/AD/-/%600510 PRADER-WILLI SYNDROME/Refractive[]

  • Secondary Glaucoma

    This was evidenced by characteristic transillumination defects in the iris. 3 In 1992, researchers suggested that posterior bowing of the peripheral iris was caused by reverse[] We present a 53-year-old man with a crystalline lens that spontaneously dislocated anteriorly with corneal touch and secondary glaucoma.[] .  Gonioscopy – pigment accumulation along the Schwalbe’s line especially inferiorly (Sampaolesi’s line)  Iris transillumination – radial slit – like transillumination defects[]

    Clinically the iris would show hypopigmentation without transillumination defects. B. Iris pigment epithelial atrophy in diabetes mellitus.[] Methionine restriction administered neonatally has been reported to prevent mental retardation and reduce the rate of lens dislocation.[] ., 2011.5.4 Mori K, Ikeda Y, Ueno M, Imai K, and Kinoshita S, Surgical outcomes of combined trabeculectomy and dislocated posterior chamber intraocular lens exchange World[]
