Presentation
CC: “I can’t make out faces with my right eye.”
HPI: 40 WM c/o blurred central vision OD after being struck by a car while changing a flat tire on an interstate off-ramp. The patient also sustained multiple rib fractures/pneumothorax and a laceration to the left ear. Transported to UL Emergency Department.

Clinical Photos
Fundus video OD demonstrating large peripapillary cotton-wool spots and superficial hemorrhages.
Inpatient Clinical Course
Patient’s left ear was surgically repaired
Thoracostomy tube was removed, stable for discharge.
Arranged to follow-up on the day of discharge in our Retina Clinic.
Dilated Fundus Exam: Clinic Photos

Purtscher’s Retinopathy
First described by Dr. Othmar Purtscher (1852–1927) in 1910.
Originally observed in two severely traumatized patients with head injuries.
Fully described in a publication in 1912 by Dr. Purtscher.
True Purtscher's retinopathy, as first described, is always associated with a traumatic injury.
When there is a non-traumatic etiology the correct designation is Purtscher-like retinopathy.

Clinical Presentation
Patients present with decreased visual acuity, often sudden (usually within 48 hours) and severe (20/200 or worse)
History of compression injury to chest, head or long bone fracture (fat embolism syndrome)
Fundoscopic signs include peripapillary cotton wool spots and/or superficial hemorrhages in over 92% of cases.
Purtscher flecken are considered pathognomic, but only occur in 50% of cases.
Typically bilateral but many times unilateral.
Purtscher-like Retinopathy
Associations include:
Acute pancreatitis
Indication of multiorgan failure and is often associated with a fatal outcome
Chronic renal failure
Childbirth (amniotic fluid embolism)
For trauma-related cases, the diagnosis is clinically apparent after fundus examination and no further workup is required.
However, cases without trauma or causative medical condition require a comprehensive medical evaluation in conjunction with an internist.
Purtscher’s Retinopathy
Pathogenesis
Thought to be a result of injury-induced complement activation, which causes granulocyte aggregation and leukoembolization.
This process in turn occludes small arterioles such as those found in the peripapillary retina.
Treatment
Anecdotal reports of limited success with high dose systemic corticosteroids.
Purtscher’s Retinopathy
Although retinal whitening and hemorrhages slowly disappear over weeks to months, usually no significant recovery of vision occurs.
Systematic Review
Mean visual acuity 20/200, range of 20/20 to LP.
Trauma and acute pancreatitis were the most frequent etiologies.
There was no statistically significant difference in VA improvement for patients treated with corticosteroids compared with observation.
Trauma and pancreatitis were associated with higher probability of visual improvement.
