Sympathetic ophthalmitis following vitreoretinal surgery: Does antecedent trauma make a difference.

ABSTRACT

Background: Sympathetic ophthalmitis (SO) has been reported following vitrectomy; however, there is a lack of data on the role of antecedent penetrating ocular trauma impacting the disease manifestation in eyes developing SO following vitrectomy. Aim: To report differences in the presentation and outcomes of SO in eyes with or without a history of antecedent penetrating trauma; SO being diagnosed after vitreoretinal (VR) surgery. Design: Comparative case series. Methods: Seventeen consecutive patients presenting with SO following VR surgery, diagnosed between 1995 and 2011 were included. Eyes with and without prior penetrating injury were included in Group I (n = 7) and Group II (n = 10), respectively. All Group I patients had received systemic steroids prior to presentation. Demographic and clinical parameters were evaluated. Results: Differences were observed between Group I and Group II mainly with regards to time interval between VR surgery and diagnosis of SO (1.5 months vs. 8 months, P = 0.10), presence of neurosensory detachments (100% vs. 30%, P = 0.01), and the inciting eye vision at presentation (nil light perception in 28.5% vs. 80%, P = 0.049). Other differences observed though not statistically significant were optic disc and retinal vessel involvement (42% vs. 70%, P = 0.28), Dalen‑Fuchs nodules (localized vs. diffuse) and leaks on fundus fluorescein angiography (pin‑head vs. pin‑point leak). Conclusion: SO in patients with antecedent penetrating ocular trauma present early with the central serous chorioretinopathy‑like picture. Prior use of systemic steroids might have a bearing on the differences in presentation and the visual acuities between the two groups.
