29 Possible Causes for Astigmatic Refractive Errors, Iridodonesis

  • Keratoglobus

    A significant decrease was also seen in mean refractive astigmatism which decreased from 5.93 (3.06) D preoperatively to 3.23 (1.14) D (p   0.037).[doi.org] Associated findings include anterior megalophthalmos, enlarged ciliary ring with zonular stretching (leading to phacodonesis), ectopia lentis, iridodonesis, iris stromal hypoplasia[medical-dictionary.thefreedictionary.com] Iridodonesis was noted in left eye.[mendeley.com]

  • Ectopia Lentis

    Retinoscopy may reveal a significant refractive error, usually myopia and astigmatism.[ncbi.nlm.nih.gov] Trembling of the iris (iridodonesis) Trembling of the lens (phacodonesis) Aphakic crescent Mild conjunctival redness Vitreous humour degeneration Prolapse of the vitreous[premilife.com] If the eye is not dilated, look for iridodonesis (abnormal tremor of the iris), phacodonesis (abnormal movement of the lens), deep anterior chamber depth or vitreous herniation[mrcophth.com]

  • Lens Dislocation

    The amount of refractive error significantly diminished 1 day after surgery (P .028 in the scleral fixation and P .046 in the iris fixation group).[ncbi.nlm.nih.gov] Iridodonesis is usually present.[ikeyes.blogspot.com] L21) See corectopia ; iridodonesis ; pupillary block. Fig.[medical-dictionary.thefreedictionary.com]

  • Marfan Syndrome

    Ocular system Findings include ectopia lentis (subluxation or upward dislocation of the lens) and iridodonesis (tremulousness of the iris).[merckmanuals.com]

  • Aphakia

    When repairing the globe, the removal of the natural lens results in a significant change in refractive error and loss of accommodation.[ncbi.nlm.nih.gov] Another distinctive sign is iridodonesis, which describes the jittering of the iris because of absent support from the lens.[symptoma.com] […] entry of infrared and ultraviolet rays in the absence of the crystalline lens Signs (anterior to posterior) Limbal scar in case of surgical aphakia Deep anterior chamber Iridodonesis[pgblazer.com]

  • Exfoliation Syndrome

    Patients with visual acuity under 0.6 according to Snellen were excluded, as well as those with refraction errors, i.e. hypermetropia over 3 spherical diopters, myopia over[ncbi.nlm.nih.gov] Phacodonesis and iridodonesis are not uncommon; they are related to zonular weakness, which may predispose affected eyes to zonular dehiscence; vitreous loss; and other complications[aao.org] Iridodonesis (movement of iris) Phacodenesis (movement of lens) May cause pupil block secondary to lens subluxation.[webeye.ophth.uiowa.edu]
