Anatomical outcome of retinal detachment surgery comparing different surgical approach

The effect of axial length on pseudophakic retinal detachment

PURPOSE

The purpose of the study was to analyse the surgical management and outcome regarding axial length in the population affected by pseudophakic retinal detachment (PRD) 2015-2020.

METHOD

The patients included were from an observational cohort study of patients undergoing cataract surgery in the region of Skåne during 2015-2017. Data were retrieved from the Swedish National Cataract Register and cross-referenced with cases of PRD in the same region from 2015 to 2020. The surgical method used and findings at follow-up were recorded. The patients were stratified according to axial length (AL) to <25 mm, 25 ≤ n < 26.5 mm and ≥26.5 mm. The main outcome was primary success with one surgery apart from silicone oil removal. The secondary outcome was postoperative visual acuity.

RESULTS

In the whole study group of 58 624 cases, complete follow-up data were available for 288 eyes. The median follow-up time was 324 days, and primary operation was successful in 82.9% of these cases. The median visual acuity was 0.31 (LogMAR). In the stratification those with AL < 25 mm had a primary success of 75.8%, AL 25 ≤ n < 26.5 mm of 87.9% and ≥26.5 mm of 95.8%.

CONCLUSIONS

The primary anatomical success was 82.9% in the whole group of PRD but with stratification they had an increasing number of primary success with longer AL.

Primary Retinal Detachment Repair in Eyes Deemed High Risk for Proliferative Vitreoretinopathy: Surgical Outcomes in 389 Eyes

PURPOSE

To evaluate surgical outcomes in eyes with primary rhegmatogenous retinal detachment (RRD) deemed at high risk for postoperative proliferative vitreoretinopathy (PVR).

DESIGN

Retrospective, consecutive case cohort study.

PARTICIPANTS

Eyes undergoing primary RRD repair with pars plana vitrectomy (PPV) or combined PPV with scleral buckling (PPV/SB) between January 1, 2016, and December 30, 2017, at Wills Eye Hospital.

METHODS

Eyes were defined as "high risk" if ≥ 1 of the following risk factors for PVR was present on preoperative examination: preoperative PVR grade A or B, vitreous hemorrhage, RRD involving ≥ 50% of retinal area, presence of ≥ 3 retinal breaks, history of prior cryotherapy, presence of choroidal detachment, or duration of RRD > 2 weeks. Surgical failure was defined as an additional intervention required for the retinal reattachment.

MAIN OUTCOMES MEASURES

Single surgery attachment success (SSAS) rate 3 months after first surgical intervention for primary RRD.

RESULTS

Of 2053 reviewed charts, a total of 389 eyes (18.9%) met the definition of high risk and were included in the analysis. Mean patient age was 63.5 years. PPV/SB was performed in 125 (32.1%) eyes and PPV alone in 264 (67.9%) eyes. SSAS rate of the overall cohort was 71.5% at 3 months. SSAS rate was significantly higher in eyes treated with PPV/SB compared with PPV (80.8% vs. 67%, respectively, P = 0.006). On multivariate analysis, use of PPV/SB was the only feature associated with SSAS (odds ratio, 2.04; 95% confidence interval, 1.12-3.69, P = 0.019).

CONCLUSION

In eyes with primary RRD and risk factors for PVR, overall SSAS was 71.5% after primary repair. In this cohort, use of PPV/SB was associated with a significantly higher SSAS compared with PPV alone.

Factors influencing compliance in RRD patients with the face-down position via grounded theory approach

Patients with rhegmatogenous retinal detachment (RRD) require face-down positioning (FDP) for 3-6 months or longer after pars plana vitrectomy (PPV) combined with silicone oil (SO) tamponade. This paper aimed to identify the factors that influenced FDP compliance. This study adopted semi-structured interviews with patients who require FDP after SO tamponade. Constructivist grounded theory was utilized in this study. The qualitative data was analyzed and coded via NVivo 11.0 through open coding, axial coding and selective coding. Twenty-four RRD patients were involved. The interviews yielded five main themes that defined home FDP compliance were identified: posture discomfort, doctor-patient communication, psychological factors, occupational character, and family factors. A theoretical model of the influencing factors of postural compliance of FDP was constructed based on the interview analysis. A variety of factors can affect FDP conformity. We can increase compliance of RRD patients by enhancing comfort, encouraging doctor-patient communication, providing comprehensive care, promoting community-based intervention, and strengthening family education.

Outer retinal features in OCT predict visual recovery after primary macula-involving retinal detachment repair

Purpose

To find predictive markers for the visual potential in optical coherence tomography (OCT) one month after surgical repair of macula-involving rhegmatogenous retinal detachment (miRD) with and without internal limiting membrane (ILM) peeling.

Methods

This retrospective single-center, single-surgeon cohort study included 74 patients who underwent pars plana vitrectomy (PPV) for primary miRD between January 2013 and August 2020 with follow-up examinations for at least 6 months. Patients developing recurrent detachments, media opacities, or with an axial length over 27 mm were excluded from the analysis. LogMAR visual (VA) and LogRAD reading acuity (RA) ± standard deviation (SD), and OCT measurements 6 months after surgery were compared to OCT and VA measurements one month after surgery using multiple linear regression analysis for predictions.

Results

VA increased from 0.34 ± 0.25 at one month to 0.22 ± 0.21 after 6 months [p < 0.001; effect size = -0.662, 95% confidence interval (CI): -(0.99–0.33)]. The continuity of the external limiting membrane (ELM) and ellipsoid zone (EZ) increased between 1 and 6 months. Subfoveal ELM integrity after one month predicted VA [adjusted R² of 8.0%, F(2, 71) = 4.17, p = 0.018] and RA [adjusted R² of 29%, F(2, 27) = 6.81, p = 0.002] after 6 months. EZ integrity had a less pronounced predictive effect on VA and RA. ELM integrity after 1 month correlated with better reading acuity after 6 months (p = 0.016).

Conclusion

VA and morphological OCT parameters improve between 1 and 6 months after surgery for miRD. The grade of ELM is a better predictor for RA than for VA, explaining more variance.
