Perioperative factors that are significantly correlated with final visual acuity in eyes after successful rhegmatogenous retinal detachment surgery.

ABSTRACT:

Purpose

To determine the perioperative factors that are significantly correlated with the final visual acuity following reattachment of a macula-off rhegmatogenous retinal detachment (RRD) by vitrectomy.

Methods

Twenty-nine eyes of 29 patients with a successfully reattached RRD by vitrectomy were retrospectively analyzed. Spectral-domain optical coherence tomographic images of the macular regions were used to measure the thicknesses of the retinal layers and the integrity of the microstructures of the photoreceptors at 2 weeks, 1, 2, 3, 6, 9, and 12 months following the vitrectomy. The best-corrected visual acuities (BCVA) were evaluated at the same times.

Results

The improvement of the BCVA from the preoperative BCVA to that at postoperative Week 2 (-0.67 ± 0.69 logMAR units) was the largest change between adjacent observation periods for the entire study duration. It was significantly greater than the improvement between Week 2 and Month 12 (-0.32 ± 0.22 logMAR units; P<0.001). The thickness of the ellipsoid zone (EZ)-retinal pigment epithelium (RPE) increased significantly with time (P<0.001). The final BCVA was significantly correlated with the BCVA at Week 2 (r = 0.61, P<0.001), the EZ-RPE thickness at Week 2 (r = -0.40, P = 0.035), the integrity of the external limiting membrane (ELM) (r = -0.61, P = 0.003), and an intact EZ (r = -0.66, P = 0.001) at Week 2. Multiple stepwise regression analyses of the final BCVA showed that the BCVA at Week 2 (P = 0.017) and the integrity of the EZ at Week 2 (P = 0.006) were independent predictors of the final BCVA.

Conclusions

The significantly better BCVA and presence of an intact EZ at 2 weeks following vitrectomy and their significant correlations with the BCVA at Month 12 indicate that these perioperative values can be used to predict the BCVA at Month 12 after a reattachment of macula-off RRD following vitrectomy.

Project description:PurposeTo describe presenting clinical features and surgical techniques that are associated with successful surgical repair of pediatric rhegmatogenous retinal detachment (RRD).DesignRetrospective interventional case series.ParticipantsTwo hundred twelve eyes of 191 patients 0 to 18 years of age undergoing surgical repair for RRD between 2001 and 2015 with a minimum follow-up of 3 months.MethodsPatients were divided into 3 age groups (0-6 years, 7-12 years, and 13-18 years) and comparisons were made using bivariate and multivariate generalized estimating equation models. A mixed means model was used to examine visual acuity in each age group over time.Main outcome measuresComplete reattachment of the retina at final follow-up.ResultsOf 212 eyes, 166 (78%) achieved total reattachment at final follow-up. Mean follow-up was 36.3 months. Rhegmatogenous retinal detachment associated with Stickler syndrome was more likely to occur in the younger cohorts (odds ratio [OR], 0.45; 95% confidence interval [CI], 0.22-0.91), whereas RRD associated with blunt trauma was more likely to occur in the oldest cohort (OR, 2.3; 95% CI, 1.2-4.4). Subtotal RRD was more likely to be repaired successfully than total RRD (OR, 3.6; 95% CI, 1.5-8.4; P = 0.0100), and eyes with previous vitreoretinal surgery were less likely to undergo successful repair (OR, 0.30; 95% CI, 0.12-0.78; P = 0.0258). There was no significant difference between age groups in the rate of surgical success (P = 0.55). There was a significantly higher success rate with primary scleral buckle (SB; 63%; OR, 2.2; 95% CI, 1.1-4.5) and combined SB plus pars plana vitrectomy (PPV; 68%; OR, 2.3; 95% CI, 1.1-5.1) compared with PPV alone (51%).ConclusionsMost pediatric patients with RRD achieved complete reattachment with surgery. Success was more common in patients with a subtotal RRD at presentation. Previous vitreoretinal surgery was a risk factor for failure. Younger patients were more likely to demonstrate RRD involving the macula, but there was no difference between age groups in successful reattachment at final follow-up. Primary PPV showed a lower rate of success than SB or combined SB plus PPV.
