Strabismus following retinal detachment repair: a comparison between scleral buckling and vitrectomy procedures.

ABSTRACT: PURPOSE: We conducted a study to investigate: (1) deviations caused by retinal detachment (RD) repair; (2) correlation between visual acuity and the number of surgeries to deviation size; and (3) differences between deviations following scleral buckling (SB) and pars plana vitrectomy (PPV). METHODS: A retrospective analysis of patients with persistent binocular diplopia following RD repair. Magnitude of manifest deviation (∣dev∣) in the primary position (PP) and position of greatest deviation (maxDev) was calculated. LogMAR acuity and number of previous vitreoretinal procedures were correlated to ∣dev∣ in both PP and maxDev. Manifest ∣dev∣ were compared between SB and PPV groups. RESULTS: Twenty-five patients were identified. The median ∣dev∣ was 7 prism diopters (PD) in PP and 17 PD in maxDev. We found no association between number of surgeries or VA with ∣dev∣ in either the PP (r=-0.18 and r=0.08) or maxDev (r=-0.26 and r=-0.05). Twelve patients underwent PPV: median ∣dev∣ in PP 6 PD and maxDev 9 PD. In the SB group: median ∣dev∣ in PP 8 PD and in maxDev 22 PD. ∣dev∣ in PP showed no significant differences between PPV and SB (U=63, P=0.41); however, ∣dev∣ in maxDev, showed that SB have significantly greater deviations (U=36.0, P=0.02). CONCLUSION: We report the largest cohort of patients with symptomatic ocular motility defects following PPV. We show no association between VA or number of procedures to strabismus magnitude. Ocular deviations in maxDev are significantly greater after SB procedures.

Project description:Purpose:To investigate the characteristics of silicone oil (SO) emulsification after vitrectomy for rhegmatogenous retinal detachment and their possible correlations with clinical factors. Methods:The first 2?mL of washing out fluid after SO removal was collected, and used for the measurement of the size and number of SO droplets using a Multisizer® 3 Coulter counter (Beckman Coulter, USA). The correlations between SO droplets and clinical factors were analyzed. Results:A total of 38 patients (23 males, 15 females) who underwent primary PPV with SO injection for RRD and whose retina stayed attached for ?3 months after SO removal were included in the study. The average number of oil droplets was 1.96?×?106?±?3.95?×?106/mL (range 0.17?×?106 to 21.71?×?106/ml), and 80.8% (range 64.23%-99.07%) of the droplets were 1-2??m in diameter. The total number of emulsified SO droplets was not correlated with any clinical factor (all P > 0.05). When the emulsified SO droplets were divided into groups by their diameter, multiple linear regression revealed that age was negatively correlated with the numbers of 5-7-?m in diameter. The total number of emulsified SO droplets was not correlated with any clinical factor (all ?m in diameter. The total number of emulsified SO droplets was not correlated with any clinical factor (all P > 0.05). When the emulsified SO droplets were divided into groups by their diameter, multiple linear regression revealed that age was negatively correlated with the numbers of 5-7-?m in diameter. The total number of emulsified SO droplets was not correlated with any clinical factor (all ?m in diameter. The total number of emulsified SO droplets was not correlated with any clinical factor (all P > 0.05). When the emulsified SO droplets were divided into groups by their diameter, multiple linear regression revealed that age was negatively correlated with the numbers of 5-7. Conclusion:Using a Multisizer® Coulter counter, we successfully determined the number and size of SO droplets after emulsification. We found that the number of 5-12-?m-diameter droplets was higher in younger-age patients and was higher in patients using antiglaucoma eyedrops.?m in diameter. The total number of emulsified SO droplets was not correlated with any clinical factor (all.

Project description:Background:Recurrent retinal detachment (RD) is still a widespread event despite the therapeutic options available. Proliferative vitreoretinopoathy (PVR) is one of the main causes of redetachment. Little is known about the use of endoscopy-assisted vitrectomy (E-PPV) in complex recurrent RD with PVR. The purpose of this study was to identify the potential advantages of E-PPV in complex RD with PVR compared with pars plana vitrectomy (PPV) alone. Methods:Single-center, retrospective, observational, descriptive study. The medical records of 293 patients were reviewed. Patients who underwent PPV for complex rhegmatogenous RD and associated PVR between 2009 and 2017 were included. Patients with diabetic tractional RD, trauma, uveitis or detachment postendophthalmitis were excluded. After 2013, an endoscopic visualization system was used in a nonrandomized fashion at the surgeon's discretion. Outcome measures (reattachment rate, number of surgeries, lens status, PVR stage, intraocular pressure, phthisis rate) were compared between the E-PPV and PPV-only groups with independent samples t-tests (continuous variables) and Fisher's exact test (categorical variables), as well as time-adjusted analyses. Postoperative time to retinal redetachment was assessed with Kaplan-Meier survival analysis. Results:One hundred one eyes from 100 patients met the inclusion criteria. The mean participant age was 63.3 years old (95% CI 60.4-66.1 years), without a significant difference between groups. E-PPV was performed in 36.6% (n?=?37) of eyes, and 63.4% (n?=?64) underwent PPV only. The mean follow-up was significantly longer in the PPV-only group (31.9 vs. 21.1 months; p?=?0.021). Upon adjustment for follow-up duration, the mean number of surgeries was significantly lower in the PPV-only group (2.6 vs. 4.3 number of surgeries; p?<?0.001) than in the E-PPV group. A significantly higher risk for redetachment was observed in the PPV-only group (HR [95% CI] 4.1 [1.4-11.8]) than in the E-PPV group (p?=?0.037). The evolution to phthisis was 7% (n?=?4) in the PPV-only group and 2.7% (n?=?1) in the E-PPV group (p?>?0.05). Conclusions:Compared to PPV alone, endoscopy-assisted vitrectomy seems to be advantageous in achieving better reattachment rates in complex RD with advanced PVR. Endoscopic visualization allows a thorough examination and extensive anterior PVR and vitreous base dissection.
