Anterior Polar Cataract

CAP


Presentation

  • Anterior pyramidal cataract may dislocate spontaneously and present as an anterior chamber foreign body and may even lead to corneal endothelial cell loss.[ncbi.nlm.nih.gov]
  • (A) When the Patient Returned for Follow-Up at Almost 7 Years, a Complete White Cataract Was Present in the Affected Left Eye.[healio.com]
  • Leukocoria or white reflex can be the presenting sign of a cataract.[emedicine.medscape.com]
Coarctation of the Aorta
  • Ocular and systemic manifestations of PHACES (Posterior fossa malformations, Hemangiomas, Arterial anomalies, Cardiac defects and coarctation of the Aorta, Eye abnormalities, and Sternal abnormalities or ventral developmental defects) syndrome.[emedicine.medscape.com]
Crying
  • And the children will, after waking up, can cry or scream or rub their eyes, and they’re often difficult to examine right after surgery.[cybersight.org]
Short Arm
  • Their genetic status resulted in partial trisomy of the long arm of chromosome 3 and partial monosomy of the short arm of chromosome 18.[ncbi.nlm.nih.gov]
  • Here we report the identification of a new locus for an autosomal dominant anterior polar cataract on the short arm of chromosome 17.[digital.csic.es]
Long Arm
  • Their genetic status resulted in partial trisomy of the long arm of chromosome 3 and partial monosomy of the short arm of chromosome 18.[ncbi.nlm.nih.gov]
  • We also excluded the cerulean cataract locus on 17q24 using marker D17S802 ( Z 3.27 @ θ 0.05), thereby excluding the known cataract and crystallin loci on the long arm of chromosome 17.[academic.oup.com]
Corneal Opacity
  • Clinical variability of autosomal dominant cataract, microcornea and corneal opacity and novel mutation in the alpha A crystallin gene (CRYAA). Am J Med Genet A. 2008; 146:833-42.[molvis.org]
  • Anterior lens opacities have also been associated with keratoconus, corneal opacities, and other congenital anomalies, which is consistent with this theory [ 7 Amaya L, Taylor D, Russell-Eggitt I, Nischal KK, Lengyel D.[benthamopen.com]
  • After microkeratome-assisted removal of the anterior stromal layers, the presence of residual corneal opacities as well as their extent may be confirmed by the iOCT.[ijo.in]
Screaming
  • And the children will, after waking up, can cry or scream or rub their eyes, and they’re often difficult to examine right after surgery.[cybersight.org]

Workup

  • It can be sporadic, autosomal dominant [44 ] or X linked. [45 ] Preoperative Workup History A good history can give a clue to aetiology.[djo.org.in]
  • […] syndrome, with affected males presenting with dense visually significant cataracts. 20 Investigations Although 60% of pediatric cataracts are idiopathic, 40 based on the antenatal history, family history, and the type of cataract, a baseline laboratory workup[dovepress.com]

Treatment

  • Treatment Treatment Options: Lens removal is indicated only if these opacities interfere with vision. References Berry V, Ionides AC, Moore AT, Plant C, Bhattacharya SS, Shiels A.[disorders.eyes.arizona.edu]

Prognosis

  • Seven other patients had additional ocular pathology which affected their visual prognosis. One patient manifested progressive lens opacification that eventually warranted cataract surgery.[ncbi.nlm.nih.gov]

  • The positive atoll sign will have more favorable prognosis since posterior capsule is intact, hence posterior chamber intraocular lens implantation will be more feasible with better visual prognosis.[jcor.in]
  • After discussion with the patient’s family, the decision was made not to perform cataract surgery because of the poor visual prognosis. Figure.[healio.com]

Etiology

  • The Framingham Eye Study did not specifically address the incidence of posterior polar cataracts as a separate group. [7] Other studies focused on incidence and etiology and nutrition. [8, 9] Etiology A posterior subcapsular cataract is a distinctive,[emedicine.medscape.com]
  • Investigation of the molecular etiology of a distinct a nterior p olar c ataract (APC) in HHCS was undertaken.[iovs.arvojournals.org]

  • Anterior pyramidal cataracts may be a more aggressive form of congenital anterior lens opacity, one that is more prone to growth and occlusive amblyopia. 9 Both anterior polar cataract and anterior pyramidal cataract likely have the same etiology: imperfect[healio.com]
  • Etiology Exact etiology is not known. Some factors which have been associated with certain types of cataracts are described below: I. Heredity. Genetically-determined cataract is due to an anomaly in the chromosomal pattern of the individual.[ikeyes.blogspot.com]

Pathophysiology

  • Pathophysiology A posterior polar cataract has an autosomal dominant inheritance pattern.[emedicine.medscape.com]
  • Future directions Despite the better understanding of pathophysiology of visual maturation in children and advancements in surgical technology and instrumentation, childhood cataract remains a challenge to pediatric ophthalmologists.[dovepress.com]

Prevention
