Request Referral Materials
To ease anxiety and ensure your patient is prepared for their first appointment, we suggest you provide them a copy of our educational print upon referral. We will mail you a referral package within 5-7 business days. To request, please fill out the form.

Research & Clinical Trials
In addition to having the latest imaging and diagnostic capabilities, we also feature an in-house clinical research program for your patients. Clinical trials have become an increasingly important option to provide the latest treatments in the hope of curing blinding diseases.

Our sub-specialists are the tertiary referral center for patients with complex auto-immune and infectious ocular conditions, intraocular tumors, and genetic disorders.
