Posterior vitreous detachment and incidence of delayed retinal breaks: a retrospective, 2-year study at an academic...

Posterior vitreous detachment (PVD) is common in older patients, particularly postcataract surgery. Patients are typically followed 4 to 6 weeks after the initial presentation. The study goal was to assess the rate of new retinal tears for patients without new symptoms on routine follow-up.

This is a multisite, retrospective cohort study of all patients presenting to the emergency departments at an academic health centre in a 2-year period diagnosed with uncomplicated PVD. Patient demographics, pastocular surgery, retinal findings at the first and second examinations, and the identity of the examiner were recorded. The primary outcome was absence of new retinal tears or pathology on follow-up.

One hundred sixty-six patients were identified, and 105 patients were present for both an initial and follow-up examination (median, 6 weeks). No patients had any new pathology on the follow-up examination. Most patients (n = 62) were seen initially by one of 15 residents alone, and most patients (n = 80) were seen at follow-up by one of 10 staff from specialties of comprehensive, uveitis, neuro-ophthalmology, cornea, and retina. The remaining 25 patients were seen in follow-up by residents.

To our knowledge, this is the first study on the incidence of delayed retinal breaks with the examination performed by a variety of residents and comprehensive and subspecialist staff. Our results suggest there may be limited benefit to routine follow-up of PVD patients without new symptoms, including when followed by nonretina ophthalmologists. These findings could allow for better health care resources management.
