Amazing Cases Managed by Optometrists in National Vision Locations

Nov 19, 2021
9 min read

We’ve all had those optometry cases—the ones where we know that if our patient had waited just a day longer, they might have never made it in at all.

  • That teenage cross country runner with the intracranial aneurysm?
  • The mother of two whose blurred vision turned out to be from a tumor—but hadn’t been able to make it to the doctor for herself this year?
  • The dad who thinks he’s perfectly healthy but has a blood pressure measurement of 200/120?

As ODs, we can sometimes get caught up in the routine of exam after exam after exam . . . but every so often we encounter a patient where we can say, yes: my intervention saved that person’s life. These life-saving interventions happen every day, and it’s amazing how much the eyes can truly tell about the body.

It doesn’t matter what setting you practice in—whether it’s a hospital, private practice, group practice, or a corporate location—you’ll see cases like these. That is the beauty of what we do as eye care professionals; we have the opportunity to make a difference every day.

There is a common misconception that optometrists just refract in corporate-affiliated settings, but it is exactly that, a misconception. Optometrists practicing in these offices have ample opportunities to treat and manage ocular disease, as well as the opportunity to impact a patient’s life.

These cases were originally collected in fall of 2018 and the information shared reflects where the OD practiced at the time the case took place.

Here we share four case studies managed by optometrists practicing in offices at National Vision retail locations where timely intervention was likely the difference between life and death.

Case Study 1: Parinaud Syndrome and Pineal Gland Germinoma


Doctor’s Exchange of Indiana, P.C.

Practices at an America’s Best Contacts & Eyeglasses location in Merrillville, IN

BACKGROUND: 12-year-old male

CHIEF COMPLAINT: The patient’s mother reported crossing of eyes for the last five months, and complaints of periodic headache over the last nine months. The patient and his mother believed his symptoms were caused from current glasses that were three years old.


Examination revealed:

  • Fixed dilated pupils, non-responsive to light
  • Poor motility in left, right, and up gaze
  • Alternating esotropia with and without current specs
  • Best corrected visual acuities were 20/60 OD and 20/30 OS.
  • Dilated fundus examination revealed blurred disc margins and hemorrhaging of both optic nerves.

TREATMENT PLAN: Bilateral papilledema in the presence of Parinaud syndrome is highly suggestive of a lesion of the dorsal midbrain. This patient was referred for imaging STAT. MRI confirmed a mass of the midbrain. Craniotomy was performed to place a shunt in order to relieve excess cerebrospinal fluid. The mass was found to be a germinoma of the pineal gland and was positive for cancer. Aggressive treatment of the cancer will include chemotherapy followed by radiation.

IMPACT ON PATIENT’S LIFE: The location of the tumor was causing obstructive hydrocephalus which can be fatal. By making the appropriate diagnosis and swiftly putting the plan into action, a life was saved. Furthermore, cancer was detected and may be appropriately treated.

Case Study 2: Type 1 Chiari Malformation


Texas Eye and Vision Associates, P.A.

Practices at an America’s Best Contacts & Eyeglasses location in San Marcos, TX

BACKGROUND: 12-year-old male patient presented for examination. He had been examined six months prior for a complete exam with unremarkable findings.

CHIEF COMPLAINT: Blurry vision OU x three days, persistent horizontal diplopia, constant, worsening occipital headache with onset concurrent with blurry vision.


Examination revealed comitant eso deviation OS of magnitude 14 prism diopters and bilateral optic nerve head edema, grade 3 OD, OS on the modified Frisen scale.

TREATMENT PLAN: Patient was referred for STAT MRI of brain/orbits with differential diagnoses of space occupying lesion, cavernous sinus syndrome, and idiopathic intracranial hypertension. Sagittal view MRI with weighted T1 contrast revealed 5 mm downward displacement of the cerebellar tonsils through the foramen magnum and into the cervical spinal column. This led to a diagnosis of Type 1 Chiari malformation.

Patient was referred to pediatric neurology and underwent successful posterior fossa decompression with duraplasty and tonsillar resection three weeks after initial diagnosis.
