  1. Infantile Cataract Mohammad Ghoreishi, MD Isfahan University of medical sciences info@persianeyeclinic.com

  2. Infantile cataract • Congenital • Present at birth • Hereditary • Non-hereditary • Developmental • Progression or development over time • Acquired • Unilateral or bilateral

  3. Etiologies, bilateral • Sporadic, not associated with any systemic or ocular diseases • Hereditary and familial • Intrauterine infections, especially “TORCH” • Metabolic disorders • Genetically transmitted syndromes Congenital Rubella Syndrome (CRS)

  4. Etiologies, unilateral • Usually isolated sporadic incidents • Associated with ocular abnormalities • Posterior lenticonus • Persistent hyperplastic primary vitreous (PHPV) • Anterior segment dysgenesis • Posterior pole tumors • Trauma • Intrauterine infection, particularly rubella. PHPV

  5. In our experience the following etiologies are frequently overlooked, they need high index of suspicion: • Galactosemia • Hypocalcemia • Diabetes • TORCH Early galactosemic cataract

  6. Leukocoria(white pupil) Differential diagnosis: • Retinoblastoma • congenital cataract • PHPV (persistent hyperplasia of primary vitreous) • Retina detachment (trauma/ retinopathy of prematurity) • Toxocariasis (nematode infection) from exposure to puppies • Uveitis, infections, other conditions It is recomended to check red reflex of all neonates & children www.occhioallaretina.it/Immagini/leucocoria.JPG

  7. Location of the opacity • Anterior polar • Anterior subcapsular • Cortical • Sutural • Lamellar (zonular)

  8. Location of the opacity • Nuclear • Posterior subcapsular • Posterior polar • Posterior lenticonus • Total

  9. Cause of visual loss • Lens opacity • Cataracts in the center of the visual axis that are greater than 3 mm in diameter are generally considered visually significant • Refractive error and anisometropia

  10. Progression • Static cataract • Anterior polar • Nuclear • Progressive cataracts • Posterior lenticonus • Persistent hyperplastic primary vitreous, • lamellar, sutural, and anterior or posterior subcapsular. • They usually have a better prognosis because they only usually begin to obstruct the vision after the critical period of visual development has passed.
