Retina Specialist, Vitreoretinal Surgery
Board Certified, American Board of Ophthalmology

Dr. Christopher Aderman is originally from Maine and completed his undergraduate studies in biochemistry at Bowdoin College, graduating magna cum laude.  He went on to study retinal disease in a lab in Boston before attending Harvard Medical school where he received his M.D. degree.  He completed his medical internship at Beth Israel Deaconess Medical Center and Harvard Medical School and his ophthalmology residency at University of California, San Francisco.  During residency he was awarded a Heed Fellowship and was one of 5 ophthalmology residents in the country to be elected to the Society of Heed Fellows.

Dr. Aderman went on to complete his vitreoretinal surgery training at Wills Eye Hospital in Philadelphia, and he was one of 4 retina fellows in the county to receive a Ron Michels Foundation Fellowship Award.  He has published numerous articles in high impact peer reviewed journals and has served as an investigator on many clinical trials.  Dr. Aderman is a board certified ophthalmologist and is an active member of the American Academy of Ophthalmology, The Association for Research in Vision and Ophthalmology, and The American Society of Retinal Specialists.

 In his spare time, Dr. Aderman enjoys hiking, cycling, skiing, and golfing.

Preparing for your Visit:

Prior to Your Appointment: Please complete and print the Patient history, HIPPA and payment policy forms even if you are an established patient. Once you have completed the forms, please bring them with you on the day of your appointment. Due to privacy issues, please do not attempt to send these forms to our office via e-mail.

Please check with your insurance company(s) to verify your “vision care” coverage for routine eye examinations by calling the customer service phone number listed on your insurance card. You may also call this same number to verify “medical” benefits for medically necessary visits and procedures.

The Day of Your Appointment:
Bring your current medical insurance card(s) with you.

  • The co-pay amount listed on your insurance card will be collected at the time of your visit.
  • For charges not covered by your individual insurance plan, payment is due at the time of service. Prompt pay discounts are available on certain services. Please ask at the front desk.

As part of your examination with us today, your pupils may be dilated. With dilation, most people experience light sensitivity and difficulty with near vision (such as reading). Some individuals also have difficulty seeing in the distance. The effects of the dilation can last several hours.
