Surgical Outcomes of Acute Retinal Necrosis-Related Retinal Detachment in Polymerase Chain Reaction-Positive Patients: A Single-Center Experience.
Ophthalmology Retina 2022 November
PURPOSE: To evaluate the clinical features, operative techniques, and surgical outcomes of patients who underwent surgery for acute retinal necrosis (ARN)-related retinal detachment (RD).
DESIGN: Retrospective, longitudinal, consecutive case series.
PARTICIPANTS: Patients with polymerase chain reaction-positive ARN presenting from 2011 to 2021 who underwent vitreoretinal surgery for ARN-related RD at our institution.
METHODS: Univariate, multivariate, and survival analyses were used to determine predictors of anatomic and functional outcomes.
MAIN OUTCOME MEASURES: Single-surgery anatomic success rate, recurrent RD, and visual acuity (VA) at 1 year.
RESULTS: Thirty-four eyes of 34 patients (32.4% women, mean age, 45.1 ± 20.4 years) were included for analysis with a median follow-up of 2.5 years (interquartile range [IQR], 0.8-5.5 years). Presenting VA was 1.1 ± 0.8 logarithm of the minimum angle of resolution (LogMAR) (Snellen ∼20/250). The median time from presentation to RD surgery was 1.7 months (IQR, 0.8-4.1 months), and the mean preoperative VA was 1.6 ± 0.8 LogMAR (Snellen ∼20/800). Small-gauge pars plana vitrectomy (PPV) with or without a scleral buckle (SB) was performed for all eyes with an overall single-surgery success rate of 63.6%, with no statistically significant differences in visual/anatomic outcomes between PPV and PPV/SB cases. Silicone oil was used for tamponade in 33 (97.1%) cases and was removed in 10 (30.3%) with good anatomic and final functional outcomes (Snellen ∼20/80). Independent predictors of recurrent RD included the female sex (hazard ratio, 8.38; 95% confidence interval, 2.03-34.68; P < 0.01) and zone 1 retinitis involvement at presentation (hazard ratio, 10.95; 95% confidence interval, 2.12-56.48; P < 0.01). The mean VA at 1 year (VA1year ) and at the final follow-up both had a Snellen equivalent of 20/640 (P > 0.05 for both compared with preoperative VA, respectively). Eyes that achieved single-surgery success had VA1year of 20/200 versus hand movements in those with single-surgery failure (P < 0.01). On multivariate linear regression, younger age (P = 0.04) and better presenting VA (P < 0.01) were both associated with better VA1year .
CONCLUSIONS: Moderate single-surgery anatomic success can be achieved with modern vitreoretinal surgical techniques for ARN-related RD, although visual outcomes remain poor. Further studies investigating interventions for increasing single-surgery success rates, for the inflammatory complications of ARN, and for preventing ARN-related RD are needed.
