Practice Philosophy

Comprehensive, evaluation-focused initial visits that often last over two hours, consolidating history, dilation, imaging, and specialist consultation into a single visit for diagnostic accuracy and convenience.
Evidence-based, subspecialty retina care modeled on academic standards, reinforced by ongoing clinical trials, regular conference-style case discussions, and a formal vitreoretinal fellowship curriculum.
Education-centered approach in which technicians and retina specialists explain findings, review imaging, and discuss treatment options (injections, laser, surgery) to support shared decision-making.
Long-term visual preservation priority is reflected in routine dilation at every visit, structured follow-up schedules, and ongoing imaging for chronic conditions like macular degeneration and diabetic retinopathy.

Descriptions for AMD or diabetic retinopathy candidates should emphasize access to anti-VEGF injections, laser, imaging-guided management, and potential eligibility for cutting-edge clinical trials within an academic-style retina program.
Descriptions for pediatric parents should stress the availability of specialized pediatric retina expertise for conditions like ROP and retinoblastoma, supported by fellowship-trained surgeons and hospital affiliations for complex surgery.
Descriptions for referring optometrists and ophthalmologists should frame the practice as a quaternary-level retina center with AUPO-accredited fellowship, robust clinical trials, multi-site access, and a history of extensive publications and complex-case management.
Descriptions for patients comparing retina providers should call out the combination of subspecialty depth (adult and pediatric retina), geographic reach, academic affiliations, and strong patient ratings as the main differentiators.
