PHACOVITRECTOMY VERSUS LENS-SPARING VITRECTOMY FOR RHEGMATOGENOUS RETINAL DETACHMENT REPAIR ACCORDING TO THE SURGICAL EXPERIENCE

Outcomes of Secondary Intracapsular Intraocular Lens Implantation in Patients following Rhegmatogenous Retinal Detachment

This study reports the outcomes of a secondary IOL implantation technique in patients that suffered from rhegmatogenous retinal detachment combined with a cataract, which included reopening the capsular bag, enabling secondary intracapsular intraocular lens (IOL) implantation. We included consecutive cases with rhegmatogenous retinal detachment (RRD) treated with vitrectomy and silicone oil tamponade, and subsequent secondary IOL implantation during silicone oil removal between September 2019 and June 2022. Demographics, pre- and postoperative clinical data, and complications were collected. Visual and refractive outcomes and IOL position were evaluated. Thirty eyes were included and followed up for a mean of 24.2 ± 5.06 months. Compared with the preoperative values, no significant changes were observed in the intraocular pressure (p = 0.170) and endothelial cell density (p = 0.336); however, the best-corrected visual acuity (Snellen: 20/83 vs. 20/38; logMAR: 0.66 ± 0.23 vs. 0.37 ± 0.32; p < 0.001) and spherical equivalent (p < 0.001) improved significantly. The mean prediction error (ME) was -0.45 ± 0.68 D (-1.9-0.54 D), and the mean absolute prediction error (MAE) was 0.62 ± 0.52 D (0.01-1.9 D). The macula-on subgroup demonstrated significantly better refractive outcomes than the macula-off subgroup (ME, p = 0.046; MAE, p = 0.008). The IOL was well positioned, with a mean horizontal and vertical tilt and decentration of 0.53 ± 0.49° and 0.21 ± 0.16 mm, and 0.54 ± 0.45° and 0.22 ± 0.16 mm, respectively. Secondary intracapsular IOL implantation provided a good and stable IOL position and satisfactory refractive outcomes, and is a feasible treatment option for patients with RRD.

Safety and efficacy of cryopexy during pars Plana vitrectomy in rhegmatogenous retinal detachment

PURPOSE

To evaluate efficacy and safety of intraoperative cryoretinopexy in cases of rhegmatogenous retinal detachment (RRD).

METHODS

In this retrospective, interventional case series, we review the medical records of 85 consecutive cases of RRD treated with pars plana vitrectomy and gas tamponade, without the use of perfluorocarbon liquids. Baseline best-corrected visual acuity, intraocular pressure, number and location of retinal breaks, location and extension of retinal detachment, duration of symptoms, macula status, presence, and grade of proliferative vitreoretinopathy (PVR) were registered. Follow-up visits were at 1 day, 15 days, 1 month and 3 months. Anatomical and functional outcomes and any adverse event were recorded.

RESULTS

Primary anatomical success was obtained in 82/85 patients (96%). During the postoperative period, PVR was observed in 4/85 cases (4.7%), 3 of whom developed recurrence of retinal detachment. 7/85 (8.2%) patients developed ocular hypertension. We built a model of logistic regression including age, sex, lens status, macula status, number of quadrants involved, number of ruptures and duration of symptoms. None of the variables considered was found to be a predictor of postoperative PVR development. Symptom's duration (β = 0.429; 95% CI = 0.009-0.023; P < 0.001) and preoperative BCVA (β = 0.273; 95% CI = 0.034-0.184; P = 0.005) were predictors for final BCVA.

CONCLUSION

These findings emphasize the safety and efficacy of the use of intraoperative cryotherapy, associated with PPV and gas tamponade, for the management of uncomplicated RRDs.

Pars Plana Vitrectomy Alone or Combined with Phacoemulsification to Treat Rhegmatogenous Retinal Detachment: A Systematic Review of the Recent Literature

Pars plana vitrectomy is today a common first-line procedure for treatment of rhegmatogenous retinal detachment (RRD). Removal or preservation of the natural lens at the time of vitrectomy is associated with both advantages and disadvantages. The combination of cataract extraction (i.e., phacoemulsification) with pars plana vitrectomy (PPVc) enhances visualization of the peripheral retina and the surgical management of the vitreous base. However, PPVc prolongs the surgical time and is associated with iatrogenic loss of the accommodation function in younger patients, possible postoperative anisometropia, and unexpected refractive results. Performance of pars plana vitrectomy alone (PPVa) requires good technical skills to minimize the risk of lens damage, and quickens cataract development. We retrieved all recent papers that directly compared PPVc and PPVa using parameters that we consider essential when choosing between the two procedures (the success rate of anatomical RRD repair, postoperative refractive error, intra- and postoperative complications, and costs). PPVa and PPVc were generally comparable in terms of RRD anatomical repair. PPVc was associated with fewer intraoperative, but more postoperative, complications. Macula-off RRD PPVc treatment was often associated with undesirable myopic refractive error. PPVa followed by phacoemulsification was the most expensive procedure.

Pars plana vitrectomy combined with phacoemulsification versus pars plana vitrectomy only for treatment of phakic rhegmatogenous retinal detachment: a systematic review and meta-analysis

PURPOSE

To compare the visual, refractive, and anatomical outcomes and incidence of complications between combined pars plana vitrectomy and phacoemulsification (phacovitrectomy) versus pars plana vitrectomy (PPV-only) in phakic eyes with rhegmatogenous retinal detachment (RRD).

METHODS

Two independent reviewers searched MEDLINE, Cochrane Central, and Web of Science to identify relevant articles. Prospective or retrospective studies comparing PPV-only and phacovitrectomy for RRD were included. Recruited studies provided information about at least anatomical success or refractive outcomes. Meta-analysis was performed for single surgery success rate, final best-corrected visual acuity (BCVA), postoperative complications, mean predicted refractive error, and mean absolute predicted refractive error.

RESULTS

Seven studies (788 eyes) were selected, including two clinical trials and five retrospective comparative case series. The single surgery success rate was similar in PPV-only and phacovitrectomy groups (risk ratio [RR] = 1.02; 95% confidence interval [CI] 0.95-1.10; P = 0.57). Mean final BCVA was significantly better in the PPV-only group than the phacovitrectomy group (MD = 0.06; 95% CI 0.00-0.12; P = 0.04). The risk of epiretinal membrane formation was significantly higher in eyes that underwent phacovitrectomy than PPV-only (RR = 2.85; 0.95% CI 1.5-5.41; P = 0.001). Phacovitrectomy group showed a more myopic final mean predicted refractive error than PPV-only group (MD = -0.31; 95% CI -0.55--0.07; P = 0.01).

CONCLUSION

There was no significant difference between the two groups regarding the anatomical outcome. Slightly better visual and refractive results were observed in the PPV-only group. However, the results should be interpreted with caution as the majority of included studies were low-quality retrospective studies.

Outcomes of Retinectomy without Lensectomy in Rhegmatogenous Retinal Detachments with Proliferative Vitreoretinopathy

PURPOSE

To report the anatomic and functional outcomes of retinectomy without lensectomy in eyes with rhegmatogenous retinal detachment (RRD) and proliferative vitreoretinopathy (PVR).

DESIGN

Retrospective, noncomparative, and interventional case series.

SUBJECTS

One hundred twelve eyes of 112 patients with RRD complicated by PVR who underwent retinectomy without lensectomy.

METHODS

Retrospective review of patients treated with vitrectomy and retinectomy without lensectomy from January 1, 2015, to January 1, 2020.

MAIN OUTCOME MEASURES

The primary outcome was the final attachment rate and single surgery anatomic success (SSAS) at 3 and 6 months after retinectomy. Secondary outcomes included predictors of final visual acuity (VA), the mean number of subsequent operations required for complete retinal reattachment, cataract surgery, and the number of eyes that ultimately had successful silicone oil removal.

RESULTS

Complete final retinal reattachment was achieved in 111 of 112 (99.1%) patients, with a mean (standard deviation [SD]) follow-up of 29 (14) months (range, 8-62 months) after retinectomy. The SSAS was achieved in 84 of 112 (75%) patients at 3 months and 73 of 112 (65.2%) patients at 6 months. The final VA improved or stabilized in 76 of 112 (67.9%) eyes. Silicone oil removal was performed in 72 of 112 patients (64.3%) at a mean (SD) of 6.6 (3.3) months, and cataract surgery was performed on 101 (90.2%) eyes before the last follow-up visit.

CONCLUSIONS

Retinectomy without lensectomy to repair RRDs complicated by PVR showed acceptable anatomic and functional results. This study suggests that removing the lens when there is no significant cataract may not be necessary in these cases to obtain reasonable outcomes.

Clinical Outcomes of Combined Phacoemulsification With Intraocular Lens Placement and Microincision Vitrectomy in Adult Vitreoretinal Disease

Purpose

To evaluate the safety and clinical outcomes of combined phacoemulsification with intraocular lens (IOL) placement and microincision vitrectomy surgery (MIVS) in adult patients with concomitant cataract and vitreoretinal disease.

Methods

A consecutive series of patients with comorbid vitreoretinal disease and cataract who had combined phacoemulsification with IOL placement and MIVS was retrospectively analyzed. The main outcome measures were visual acuity (VA) and intraoperative and postoperative complications.

Results

The analysis comprised 648 eyes of 611 patients. The median follow-up was 26.9 months (range, 12-60 months). The most common vitreoretinal pathology was intraocular tumor (53%). The best-corrected Snellen VA improved from 20/192 at baseline to 20/46 at the 12-month follow-up. The most frequent intraoperative complication was capsule tear (3.9%). The most common postoperative adverse events after 3 months of follow-up (mean, 24 months) were vitreous hemorrhage (3.2%) and retinal detachment (1.8%). No patient developed endophthalmitis.

Conclusions

Combined phacoemulsification with IOL placement and MIVS is a safe, effective technique to manage a broad range of vitreoretinal diseases in patients with significant cataract.

COMPARISON BETWEEN SCLERAL BUCKLING AND VITRECTOMY IN THE ONSET OF CYSTOID MACULAR EDEMA AND EPIRETINAL MEMBRANE AFTER RHEGMATOGENOUS RETINAL DETACHMENT REPAIR

PURPOSE

To investigate the incidence and risk factors for the main complications in patients with rhegmatogenous retinal detachment treated with scleral buckling (SB) or pars plana vitrectomy (PPV).

METHODS

A retrospective, comparative, observational study was conducted. The medical records of 107 patients with primary rhegmatogenous retinal detachment who were managed with SB (n = 57) or PPV (n = 50) were reviewed. Scleral buckling was performed using scleral encircling solid silicone band and circumferential solid silicone exoplant to support the break. Pars plana vitrectomy was combined with phacoemulsification in phakic eyes and with scleral encircling in inferior detachments. Follow-ups, including spectral-domain optical coherence tomography examination, were scheduled at 1, 3, and 12 months after surgery. Propensity score matching was used to adjust for potential preoperative selection bias.

RESULTS

The overall incidence of postoperative cystoid macular edema (CME) and epiretinal membrane was 14.95% and 30.84%, respectively. Compared with SB, CME was more frequent in the PPV (P = 0.021) and in the PPV pseudophakic eyes (P = 0.027). Postoperative CME was an early, predominantly transient complication and regressed in 67% of SB and in 77% of PPV eyes within 12 months after surgery. No differences were observed regarding epiretinal membrane development. Except for the surgical technique, no preoperative factors associated with CME were identified. A correlation between epiretinal membrane and patients' age was found (P = 0.028).

CONCLUSION

The incidence of CME after rhegmatogenous retinal detachment repair was higher in patients who underwent PPV, either alone or combined with phacoemulsification, than in those treated with SB. Epiretinal membrane development was correlated to older age, regardless of the surgical procedure.

Rhegmatogenous retinal detachment repair-does age, sex, and lens status make a difference?

PURPOSE

To analyze the correlation between lens status, age, and sex in the epidemiology and success rates of rhegmatogenous retinal detachment (RRD) surgery.

METHODS

The files of all consecutive patients undergoing vitreoretinal surgery for uncomplicated RRD between Jan 2005 und Dec 2020 were retrospectively reviewed. Successful outcome was defined as no retinal redetachment occurring within 3 months after surgery.

RESULTS

5502 eyes with uncomplicated primary RRD were included. Mean age of the patients was 61.1 years (± 13.6 SD). In the age group over 40 years, a male predominance was found. The percentage of pseudophakic RRD increased from 25 to 40% during the 15 years observation period. In the age group 50 to 69 years, patients with pseudophakic detachments were male in 786 out of 1079 cases (72.9%). In the same age group, 1285 of 2110 (60.9%) patients with phakic RRD were male. Overall, primary success rate after one procedure was 91.2% (5018 of 5502). In the phakic eyes, the primary success rate was higher in those eyes that underwent combined phacovitrectomy (93.0%), compared to those without simultaneous cataract surgery (88.7%; p = 0.002).

CONCLUSION

The ratio of male and female patients with RRD varies between age groups. The proportion of pseudophakic RRD has increased within 15 years. The male predominance in RRD is stronger in pseudophakic than in phakic eyes. In phakic eyes with RRD, a combined phacovitrectomy yielded better anatomical results.

Regional and sex differences in retinal detachment surgery: Japan-retinal detachment registry report

It is known that social factors affect the choice of treatments, and special attention has been paid to sex differences. The purpose of this study was to determine whether regional and sex differences exist in the treatment of rhegmatogenous retinal detachment (RD). We used Japan-RD Registry database of 2523 patients aged ≥ 40 years between February 2016 and March 2017 in 5 Japanese regions. Regional differences of patients' perioperative factors were analyzed. The factors affecting the proportion of patients who underwent surgery within one week of the onset, defined as early-surgery, were examined by logistic regression. We observed regional differences in perioperative factors, especially in the use of phacovitrectomy, general anesthesia, and air-tamponade, which was higher in certain regions. (Fisher's exact test, all P = 0.012) The proportion of early-surgery was significantly higher among men in Kyushu region (Odds ratio (OR) 1.83; 95% confidence interval (CI) 1.08-3.12; P = 0.02), and it was also significantly higher after adjusting for covariates (OR 1.89; 95% CI 1.06-3.42; P = 0.02). Regional and sex differences exist in the treatment of RD in Japan. Although there was no significant differences in the anatomical outcomes, women in certain regions of Japan are less likely to receive early surgical intervention for RD.
