Eye Disease Evaluation

An eye disease evaluation is a focused medical examination to investigate a symptom, an abnormal finding from another exam, or a systemic condition that affects the eye. It combines the relevant parts of a comprehensive exam with the imaging and tests the question requires, and ends with a diagnosis, a plan and a follow-up interval. It is usually billed to medical insurance, and it is the right visit when something is wrong rather than when a routine check is due.

When to book an evaluation rather than a routine exam

  • Blurred vision that glasses do not fix, or vision that fluctuates
  • A red, painful or light-sensitive eye
  • New floaters, flashes or a shadow in the vision, which are urgent: call right away
  • Distortion of straight lines, or a blurred patch in the center of vision
  • Persistent dryness, grittiness or watering
  • Double vision, drooping lids or unequal pupils
  • A finding from an optometrist or physician, such as high eye pressure, a suspicious optic nerve or retinal changes
  • A systemic condition with eye effects: diabetes, high blood pressure, autoimmune or thyroid disease, or a medication that needs eye monitoring

What the evaluation involves

The visit starts with the history of the problem, then the examination and testing follow from it. A dry eye complaint leads to tear film testing and gland imaging; a glaucoma suspect to pressure, gonioscopy, OCT and visual fields; a retinal symptom to dilation and macular OCT; a corneal problem to topography and tomography. Many evaluations reach a diagnosis in one visit; some need a second visit for repeat or specialized testing. You leave knowing what has been found, what it means, and what happens next.

Diagnosis and next steps

The outcome may be treatment started here, monitoring at a set interval, a referral to a retina, glaucoma or oculoplastic specialist we work with, or reassurance that the eye is healthy and the symptom benign. A report goes to your referring doctor or primary care physician where appropriate.

Urgent symptoms

Sudden loss of vision, a curtain or shadow, severe eye pain, a painful red eye in a contact lens wearer, chemical injury or trauma are urgent. Call (855) 456-2253 and tell us it is urgent; a physician is on call 24/7 for our patients. For severe symptoms, go to the nearest emergency department.

Frequently Asked Questions

No. Patients can book directly, and referrals from optometrists and physicians are welcome. Some HMO plans require a referral for coverage, which our team will check.

Typically 60 to 90 minutes, depending on the testing needed. Dilation is often part of it, so bring sunglasses and a driver if possible.

Often, yes, when the diagnosis is clear: drops for infection or inflammation, or a plan for dry eye. A retinal tear is sealed with laser by a retina specialist we refer you to, and some conditions need further testing first.
