Questions to Ask Your Doctor

At the Jack McGovern Coats’ Disease Foundation, we receive many emails from scared patients and/or parents looking for answers about their children’s diagnosis. What type of treatment is best? Is the diagnosis of Coats’ Disease correct? Could Coats’ Disease be hereditary? While there has been advancements in treatment and research into this disease, it is imperative for parents and patients to discuss all aspects of their Coats’ Disease diagnosis directly with an ophthalmologist and other doctors who are knowledgeable about Coats’ Disease and your specific case.

These questions below often come up and should be considered as you and your doctor decide the best approach for treatment.  Of course, these questions do not constitute any form of medical advice or diagnosis.  Please realize that your situation, or that of your child, is bound to be unique in some fashion, and only the advice of your own doctor should be used in individual diagnosis and treatment.




Ahead of any treatments or procedures, it is important to ask yourself and the doctor the following questions:

  • How do you know that this is Coats’ Disease?
  • Has your doctor treated other patients with Coats’ Disease?
  • Have you sought a second opinion? If not, please consult our Doctor Directory for knowledgeable doctors in your area.


  1. What Stage of Coats’ Disease is he/she in?
  • Will his/her vision get worse over time?
  • Will his/her eye have pain?
  • Will the eye start to turn out? Is muscle corrective surgery an option?
  • Are cataracts likely?
  • How likely is glaucoma? (due to retinal detachment)
  • Is there calcification?
  • What is the anticipated disease progression?
  1. Is there a thorough vision exam available?
  • Where is the vision affected? (central /peripheral/ distance)
  • Does he /she have depth perception? (3D visibility)
  • Is there color blindness?
  • What about the non-Coats’ eye?
  • To what extent is his / her vision affected?
  • Will we be able to use this as a baseline to measure progress/decline?


  1. If there is a retinal detachment:
  • What percent is the retina detached?
  • Will it continue to detach?
  • How quickly can it detach?
  • Can you treat with laser or freezing treatment (cryotherapy)?
  • Is reattachment surgery advised?
  • What are the risks associated with reattachment surgery?  (i.e. further vision loss/re-detachment/success rate?)
  • Will you be doing retinal mapping to compare progress
    with laser/cryotherapy?


  1. Is laser/cryotherapy always successful?
  • What are the risks with scarring?
  • What about alternatives such as Avastin / Lucentis which can help prevent new blood vessel growth?
  • Is there a risk when using these anti-VEGF’s to the rest of the body?


  1. Is shrinking of the eye something to watch?
    •   What about pain in the eye – is that something to be anticipated? If so, would that indicate a need for removal of       the eye (enucleation)?
