The [[Ocular]] and [[renal]] [[anomalies]] are the most important diagnostic findings representing in patients with characteristic signs and symptoms. Mutation in [[PAX2]] Gene causes [[optic disc]] [[dysplasia]] and [[coloboma]] seen in most of the cases is due to the failure of the choroidal fissure to close. Despite the similarities with [[Colomba]] and [[morning glory]] anomaly, significant differences exist such that [[optic disc]] [[dysplasia]] cannot be classified as either one entity. [[Optic disc]] [[dysplasia]] is noted by an ill-defined inferior excavation, the convoluted origin of the [[superior retinal vessels]], an excessive number of vessels, [[infrapappilary]] pigmentary disturbance, and slight band of [[retinal]] elevation adjacent to the disk. Some patients have the 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]]. The most common malformation in patients with the syndrome is [[kidney hypoplasia]], which is small and underdeveloped kidneys, often leading to [[end-stage renal disease]] (ESRD). Estimates show approximately 10% of children with [[hypoplastic kidneys]] are linked to the disease. Many different [[histological]] abnormalities have been noted, including a decrease in [[nephron]] number associated with [[hypertrophy]], [[focal segmental glomerulosclerosis]], [[interstitial fibrosis]], and [[tubular atrophy]], [[multicystic dysplastic kidney]]. | |||

Overview
The Ocular and renal anomalies are the most important diagnostic findings representing in patients with characteristic signs and symptoms. Mutation in PAX2 Gene causes optic disc dysplasia and coloboma seen in most of the cases is due to the failure of the choroidal fissure to close. Despite the similarities with Colomba and morning glory anomaly, significant differences exist such that optic disc dysplasia cannot be classified as either one entity. Optic disc dysplasia is noted by an ill-defined inferior excavation, the convoluted origin of the superior retinal vessels, an excessive number of vessels, infrapappilary pigmentary disturbance, and slight band of retinal elevation adjacent to the disk. Some patients have the 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. The most common malformation in patients with the syndrome is kidney hypoplasia, which is small and underdeveloped kidneys, often leading to end-stage renal disease (ESRD). Estimates show approximately 10% of children with hypoplastic kidneys are linked to the disease. Many different histological abnormalities have been noted, including a decrease in nephron number associated with hypertrophy, focal segmental glomerulosclerosis, interstitial fibrosis, and tubular atrophy, multicystic dysplastic kidney.
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, the convoluted origin of the superior retinal vessels, excessive number of vessels, infrapappilary pigmentary disturbance, and a slight band of retinal elevation adjacent to the disk.[3] Some patients have a 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[4], 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]
