While all physicians at EyeHealth Northwest are trained to diagnose and care for patients with routine retinal problems, there are some situations that require more specialized care. Doctors Jonathan Yoken, MD, Brian T. Chan-Kai, MD and Elizabeth Verner-Cole are fellowship trained Vitreoretinal subspecialists who are available for consultation, second opinions and on-going care.

Most common conditions treated:

  • Macular Degeneration
  • Diabetic Retinopathy
  • Retina Tears
  • Retinal Detachment
  • Retinal Vein Occlusion

As you visit our Retinal Specialists, you will note that often times there can be numerous elements to your exam.
Please familiarize yourself with the following to ensure that you have a comfortable and informed exam:

  1. You need to plan to be dilated for every exam. Retinal Specialists treat the retina which is located at the back of your eye. Dilating the pupils of your eye is the only way the physician can assess the health of your retina effectively.
  2. It is very common to have retina imaging that accompanies your visit to the Retina Specialists. These images help the physician diagnose, treat and monitor various retinal problems.
  3. A typical exam is 2 hours or more due to the extensive nature of retinal testing and frequent emergent nature of some retinal diseases. Please plan ahead of time to have assistance with driving to and from the clinic. Driving with dilated pupils is not encouraged.
  4. Due to the length of the average retinal appointment, EyeHealth Northwest recommends diabetic patients come prepared with a snack or drink to help regulate your blood sugar.
