Large Traumatic Retinal Dialysis Associated With Prominent Vitreous Base Avulsion

A 13-year-old female with a history of regressed retinopathy of prematurity presented with new-onset floaters after sustaining blunt force trauma to her left eye. Best-corrected visual acuity was 20/20 in both eyes (OU), with an intraocular pressure of 14 mm Hg and 15 mm Hg in the right eye (OD) and left eye (OS), respectively. Exam under anesthesia revealed an unremarkable anterior segment OU, including no hyphema or subluxated crystalline lens. Scleral depression OS demonstrated a retinal dialysis superotemporally (1-o'clock to 3-o'clock) and nasally (7-o'clock to 10-o'clock) associated with a prominent vitreous base avulsion but no subretinal fluid (Figure). Scleral depression OD was unremarkable. Both areas of retinal dialysis OS were treated with three rows of indirect green laser photocoagulation posterior to the edge of the dialysis.
