Overview

History and Symptoms

Ocular Defects

Ocular disc dysplasia is the most notable ocular defect of the disease. An abnormal development in the optic stalk causes optic disc dysplasia, which is caused by a mutation in the Pax2 gene.[1] The nerve head typically resembles the morning glory anomaly, but has also been described as a colomba.[1] A colomba is the failure to close the choroid fissure, which is the opening from the ventral side of the retina in the optic stalk.[2] Despite the similarities with colomba and morning glory anamoly, significant differences exist such that optic disc dysplasia cannot be classified as either one entity.[3]

Optic disc dysplasia is noted by an ill defined inferior excavation, convoluted origin of the superior retinal vessels, excessive number of vessels, infrapappilary pigmentary disturbance, and slight band of retinal elevation adjacent to the disk.[3] Some patients have normal or near normal vision, but others have visual impairment associated with the disease, though it is not certain if this is due only to the dysplastic optic nerves, or a possible contribution from macular and retinal malformations.[1] The retinal vessels are abnormal or absent, in some cases having small vessels exiting the periphery of the disc. There is a great deal of clinical variability.[1]

Kidney Defects

The most common malformation in patients with the syndrome is kidney hypodysplasia, which are small and underdeveloped kidneys, often leading to end-stage renal disease (ESRD).[4] Estimates show approximately 10% of children with hypoplastic kidneys are linked to the disease.[5] Many different histological abnormalities have been noted, including:

  • decrease in nephron number associated with hypertrophy
  • focal segmental glomerulosclerosis
  • interstitial fibrosis and tubular atrophy
  • multicystic dysplastic kidney[4]

Up to one-third of diagnosed patients develop end stage kidney disease, which may lead to complete kidney failure.[4]
