*Managing the patients for hypertension and the vesicoureteral reflux that might be affecting the long-term renal outcome and the renal function.
Measurement of renal function by serum electrolyte concentrations, BUN, and creatinine
*This helps in preventing the development of end-stage renal disease in patients.
Urinalysis to evaluate for the presence of blood and protein
*ESRD if develops -  dialysis, and/or renal transplantation.
Evaluation for vesicoureteral reflux, by voiding cystourethrogram (VCUG)
*Vision experts or ophthalmologists are helpful in correcting the vision and help in the occurrence of significant vision loss.<br />
Dilated eye examination
Audiologic assessment (See Deafness and Hereditary Hearing Loss Overview for details of audiological assessment.)
Consultation with a clinical geneticist and/or genetic counselor
Treatment of Manifestations
A team approach that includes specialists in ophthalmology, nephrology, audiology, and clinical genetics is recommended.


Management is focused on preventing complications of end-stage renal disease (ESRD) and/or vision loss resulting from retinal detachment.
==Prevention==


Ongoing treatment of hypertension and/or vesicoureteral reflux (if present) may preserve renal function.
===Prevention of secondary complications===
ESRD is treated with renal replacement therapy (i.e., dialysis and/or renal transplantation).
Prevention of secondary complications is usually performed for the patients having some form of congenital abnormalities.
Low vision experts can assist with the adaptive functioning of those with significant vision loss.
Prevention of Secondary Complications
Prevention of retinal detachment in those with congenital optic nerve abnormalities includes close follow up with an ophthalmologist and use of protective eyewear.


Surveillance
*If patient is having congenital optic disc abnormalities the secondary prevention is done
No disease-specific guidelines have been developed. The following ongoing evaluations are recommended in all individuals with PAX2-related disorder.
*close follow-up with the ophthalmologist and protective eyewear.


Follow up by a nephrologist to monitor renal function and blood pressure
===Avoid===
Follow up by an ophthalmologist to monitor vision. Any change in vision could indicate a retinal detachment and should be treated as a medical emergency.
Avoid the use of medications and substances that can negatively impact one's kidney function.
Audiometric evaluation with periodic follow-up
Agents/Circumstances to Avoid
Avoid the following:


Use of medications known to affect renal function (requires consultation with a specialist in nephrology)
*A nephrologist should always be consulted before starting any medication to avoid any impairment in kidney function.
Contact sports
*Patients are also instructed to avoid contact sports.
Evaluation of Relatives at Risk
It is appropriate to clarify the genetic status of apparently asymptomatic at-risk relatives of an affected individual by molecular genetic testing of the PAX2 pathogenic variant in the family in order to identify as early as possible those who would benefit from prompt initiation of treatment and preventive measures.


See Genetic Counseling for issues related to testing of at-risk relatives for genetic counseling purposes.
===Evaluation of Relatives at Risk===
It is the most important component in patients with renal coloboma syndrome.


Pregnancy Management
*It is acceptable to evaluate and clarify the genetic status of asymptomatic relatives of patients with Renal-coloboma syndrome.
It is important that a female with PAX2-related disorder have a thorough renal evaluation prior to becoming pregnant. Individuals with clinical renal disease should consult with appropriate professionals including nephrologists and maternal-fetal medicine specialists to establish a plan for medical management during pregnancy.
*It is usually done with the help of genetic testing of the PAX2 pathogenic variant
*To identify asymptomatic family members so a to identify any family member that could be benefited from the therapy.

Medical Management

The medical management[1] for the patients suffering from Renal-coloboma syndrome consists of a combination of preventive as well as a curative component for the complications or the clinical manifestations happening in patients clinically. The most important component is the clinical evaluation of patient symptoms and signs. The most common evaluation involves a careful assessment of Renal and optical manifestations. The following test and workup should be done in patients if not already done to cover up all the possible aspects of clinical manifestations.

Early Evaluation

1) Evaluation of Renal structure by renal ultrasound

2) Urinalyses to look for the presence of blood and proteins

4) Measurement of renal function by renal by checking serum electrolyte concentration, creatinine, and BUN concentration levels.

4) Voiding Cystourethrogram

5) Eye and ear examination- Audiologic testing to look for the presence of hearing loss.

6) Genetic counseling

7) Team approach that usually includes ophthalmologist, nephrologist, audiologist along with clinical genetic specialist.

Prevention of complications

The prevention of complications is the most important component involved in patient care.

Most importantly focuses on the prevention of

  • Development of ESRD
  • Vision Loss resulting from the detachment of retinal epithelium.

Treatment for ongoing symptoms and complications

The treatment approach for patients with Renal-coloboma syndrome mainly involves the team of Nephrologists, Ophthalmologists, Audiologists. The ongoing treatment helps in the better control of symptoms and giving patients a better quality of life.

  • Managing the patients for hypertension and the vesicoureteral reflux that might be affecting the long-term renal outcome and the renal function.
  • This helps in preventing the development of end-stage renal disease in patients.
  • ESRD if develops - dialysis, and/or renal transplantation.
  • Vision experts or ophthalmologists are helpful in correcting the vision and help in the occurrence of significant vision loss.

Prevention

Prevention of secondary complications

Prevention of secondary complications is usually performed for the patients having some form of congenital abnormalities.

  • If patient is having congenital optic disc abnormalities the secondary prevention is done
  • close follow-up with the ophthalmologist and protective eyewear.

Avoid

Avoid the use of medications and substances that can negatively impact one's kidney function.

  • A nephrologist should always be consulted before starting any medication to avoid any impairment in kidney function.
  • Patients are also instructed to avoid contact sports.

  • It is acceptable to evaluate and clarify the genetic status of asymptomatic relatives of patients with Renal-coloboma syndrome.
  • It is usually done with the help of genetic testing of the PAX2 pathogenic variant
  • To identify asymptomatic family members so a to identify any family member that could be benefited from the therapy.
