When Should You See an Ophthalmologist or Retina Specialist?
An ophthalmologist diagnoses and treats a full range of eye conditions. A retina specialist (ophthalmologist with additional training) focuses on the back of the eye – the retina, macula, and vitreous – where many serious vision threats originate. Dr. Cai brings emergency medicine expertise from two of the country’s leading eye emergency departments, with experience managing urgent retinal presentations and vision-threatening emergencies.
Comprehensive Eye Exams & Diagnostics
If you have diabetes, high myopia (nearsightedness), glaucoma, cataracts, or a family history of eye disease, comprehensive evaluation by an ophthalmologist is essential for early diagnosis and treatment. Dr. Cai provides full diagnostic workups including advanced imaging (OCT, fundus photography) to identify and manage conditions that threaten vision.
