Aniridia: Causes & Reasons

Possible Causes for Aniridia

Sporadic aniridia mutations may affect the WT1 region adjacent to the AN2 aniridia region, causing a kidney cancer called nephroblastoma (Wilms tumor). [diki.pl]

Wilms' tumor occurs more frequently in children with certain abnormalities or syndromes present at birth, including: Aniridia. [mayoclinic.org]

Aniridia in some individuals is associated with kidney nephroblastoma (Wilms tumor), genitourinary anomalies, or mental retardation and cerebellar ataxia (Gillespie syndrome [diki.pl]

Aphakia

We report a case of aniridia associated with congenital aphakia and secondary glaucoma. [ncbi.nlm.nih.gov]

Examination showed partial aniridia and aphakia. [ncbi.nlm.nih.gov]

Aniridia was probably the result of the relatively large wound used to implant the nonfoldable IOL. [ncbi.nlm.nih.gov]

Axenfeld-Rieger Syndrome

The patient was referred to our institute when she was four years old with an uncertain diagnosis of ARS versus aniridia. [molvis.org]

Rarely, isolated aniridia is caused by mutations in FOXC1 [ 8, 9 ] or PITX2 [ 10 ]. [journals.plos.org]

Peters Anomaly

We report a child with aniridia and Peters anomaly associated with a PAX6 gene mutation. [ncbi.nlm.nih.gov]

At birth he showed bilateral buphthalmos with aniridia and congenital corneal opacities, agreeing with Peters' anomaly. A keratoplasty was performed. [ncbi.nlm.nih.gov]

Only 1 patient had PAX6 mutation-confirmed aniridia. The other 2 patients had partial iris defects. [ncbi.nlm.nih.gov]

Ectopia Lentis

Lens Dislocation

Aniridia • Cataract Surgery • Dislocated IOL, subluxed IOL A patient suffered repeat trauma 3-years prior to a traumatic cataract which required a Rauch-Rosenthal aniridia [eyetube.net]

If hereditary, it is usually bilateral and associated with other disorders (e.g., aniridia, Marfan's syndrome). It may be complicated by cataract formation. [tsbvi.edu]

Here, Lisa Arbisser, MD, walks through her strategy to suture and recenter the aniridia ring-bag-lens complex in the presence of extensive zonular loss. [eyetube.net]

Denys-Drash Syndrome

Unlike WAGR (Wilms tumor, aniridia, genitourinary anomalies, and mental retardation) syndrome, with its complete deletion of one copy of WT1, Denys-Drash syndrome is generally [ncbi.nlm.nih.gov]

Several overlapping phenotypes are associated with WT1 mutations, including Wilms tumors, Denys-Drash syndrome (DDS), Frasier syndrome (FS) and WAGR syndrome (Wilms tumor, aniridia [ncbi.nlm.nih.gov]

Aniridia is typically the first noticeable sign of WAGR syndrome. [invitae.com]

Hereditary Nystagmus

Living with aniridia Daily life with aniridia requires constant adaptation with the environment. [aniridia.eu]

ANIRIDIA Aniridia is a hereditary condition where the iris of the eye is underdeveloped. [nfb.org]

Associated syndromes include Aniridia (autosomal dominant) and anterior segment dysgenesis syndromes (both are autosomal dominant). [centogene.com]

The presence of macular hypoplasia in association with the iris and corneal changes suggests that autosomal dominant keratitis is likely a variant of aniridia. [ncbi.nlm.nih.gov]

Mutations or deletions of PAX6 were first identified in patients with aniridia [ 9, 10 ]. [molvis.org]
