Phenotype and Outcomes of Phakic Versus Pseudophakic Primary Rhegmatogenous Retinal Detachments: Cataract or Cataract Surgery Related?

Retinal Tear and Retinal Detachment Following Cataract Surgery in Eyes with a Previous History of Treated Phakic Retinal Tears

OBJECTIVE

To investigate the incidence and outcomes of retinal tear (RT) and retinal detachment (RD) after cataract extraction in patients with a history of previous phakic RT.

DESIGN

Retrospective case series.

SUBJECTS

Phakic eyes with RT that were successfully treated with laser photocoagulation or cryotherapy and subsequently underwent cataract surgery.

METHOD

A retrospective review of phakic eyes treated for RTs between April 1, 2012 and May 31, 2023 was performed. Exclusions included prior vitreoretinal surgery before cataract removal and follow-up of less than 6 months post-cataract surgery.

MAIN OUTCOME MEASURES

The incidence of RTs and RDs after cataract surgery, along with visual and anatomic outcomes.

RESULTS

Of 12,109 phakic eyes treated for RTs, 1039 (8.6%) eyes underwent cataract surgery. After exclusions, 713 eyes of 660 patients were studied. The mean (standard deviation, SD) follow-up period post-cataract surgery was 34.8 (24.6) months with a median of 239 and 246 days to a new RT or RD development. The overall incidence for diagnosis of post-cataract surgery RT and RD was 7.3% (52/713) (2.9% and 4.3%, respectively), with a one-year incidence of 5.6% (2.2% and 3.4%, respectively). Multivariable regression analysis identified a higher risk of RT/RD among younger individuals (odds ratio [OR] 1.034; 95% confidence interval [CI] 1.004-1.065, P=0.028), males (OR 2.058; 95% CI 1.110-3.816, P=0.022), and those with shorter interval between laser treatment and cataract surgery (OR 1.001; 95% CI 1.001-1.001, P=0.011). Single surgery anatomic success for the RD repair was achieved in 25 eyes (80.6%) at 3 months, with a 100% final reattachment rate. The median final logMAR visual acuity was 0.10 (20/25) for RT, showing no significant change from post-cataract surgery, and 0.18 (20/30) for RD, a significant worsening from after cataract surgery.

CONCLUSION

One year post-cataract surgery, the rate of diagnosed RT and RD in patients with previously treated RTs was relatively high, occurring in nearly 1 in 18 eyes. Higher risk was noted among younger individuals, males, and patients with a shorter interval between initial treatment for RT and cataract surgery. RD repair achieved good anatomical results, but vision declined.

Incidence and Outcomes of Recurrent Retinal Detachment after Cataract Surgery in Eyes with Prior Retinal Detachment Repair

OBJECTIVE

To investigate the incidence and outcomes of recurrent retinal detachment (RD) after cataract extraction (CE).

DESIGN

Retrospective case series.

SUBJECTS

Phakic eyes with RD that were successfully repaired with pneumatic retinopexy (PR), scleral buckle (SB), pars plana vitrectomy (PPV), or combined PPV/SB and subsequently underwent cataract surgery.

METHODS

A retrospective review of phakic eyes that underwent successful RD repair followed by subsequent cataract surgery between April 2012 and January 2023 was performed. Patients with multiple RD surgeries before CE and those with silicone oil tamponade before cataract surgery were excluded. Eyes that redetached were matched 1:2 with eyes that did not redetach after cataract surgery.

MAIN OUTCOME MEASURES

Incidence of redetachment after cataract surgery as well as visual and anatomic outcomes at 6 months after first redetachment and at the final visit.

RESULTS

Of 4833 phakic eyes at the time of initial RD, 1893 patients (39.2%) underwent cataract surgery. After applying exclusion criteria, 763 patients were included. The mean (standard deviation) duration of follow-up was 48.4 (29.1) months. The overall incidence of retinal redetachment after cataract surgery was 2.5% (19/763 eyes). The rate of redetachment based on the type of initial RD repair was 9.1% (1/11), 5.3% (2/38), 2.8% (9/317), and 1.8% (7/397) for PR, SB, PPV, and combined PPV/SB, respectively (P = 0.24). The median (interquartile range [IQR]; range) duration between the cataract surgery and first redetachment was 301 (104-1222; 8-2760) days. Single surgery anatomic success for the RD repair after cataract surgery was achieved in 17 eyes (89.5%) at 3 months and 14 eyes (73.7%) at 6 months and at the final visit. Final anatomic success rate for reattachment was 100% (19/19). The median (IQR) logarithm of the minimal angle of resolution visual acuity (VA) at the final visit was 1.00 (0.18-2.00, Snellen equivalent, 20/200) with significant worsening compared with vision after cataract surgery (0.18 [0.10-0.48], 20/30) (P = 0.001).

CONCLUSION

Recurrent RD was not uncommon in patients with a prior history of RD repair after CE. Reoperation resulted in relatively favorable anatomic success but there were declines in VA.

SF 6 COMPARED WITH C 2 F 6 FOR INFERIOR RHEGMATOGENOUS RETINAL REPAIR : The Manchester Pseudophakic Retinal Detachment Study

PURPOSE

To compare SF 6 relative with C 2 F 6 in the anatomical and functional outcomes following pars plana vitrectomy for uncomplicated primary pseudophakic rhegmatogenous retinal detachment with inferior causative breaks.

METHODS

This is a retrospective, comparative study on eyes with pseudophakic rhegmatogenous retinal detachment with inferior causative breaks that had small-gauge pars plana vitrectomy repair using SF 6 and C 2 F 6 tamponade between 2011 and 2020 at a tertiary centre in the United Kingdom. Primary outcome was single surgery anatomical success, and the secondary outcome was best-corrected visual acuity. Propensity score matching, using preoperative findings as covariates to account for relevant confounders, was performed.

RESULTS

From 162 pseudophakic rhegmatogenous retinal detachment eyes with inferior causative breaks, the median (interquartile range) follow-up was 82 (52-182) days. The single surgery anatomical success was 156 (96.3%) overall: 47 of 47 (100.0%) and 109 of 115 (94.8%) in the SF 6 and C 2 F 6 groups, respectively ( P = 0.182). Relative to the SF 6 group, the C 2 F 6 group had a higher mean number of tears (SF 6 : 3.1[2.0], C 2 F 6 : 4.5[2.7], P = 0.002) and greater retinal detachment extent (SF 6 : 5.3[2.9], C 2 F 6 : 6.2[2.6] clock hours, P = 0.025). Following propensity score matching analysis, 80 eyes were matched with 40 in each group to homogenize preoperative factors. No significant difference was found in single surgery anatomical success and best-corrected visual acuity between the groups following propensity score matching.

CONCLUSION

Primary pars plana vitrectomy with gas tamponade leads to a high single surgery anatomical success rate in uncomplicated pseudophakic rhegmatogenous retinal detachment with inferior causative breaks with no additional benefit associated with long-acting tamponade when comparing C 2 F 6 with SF 6 .

THE LONG-TERM RECOVERY OF VISION IN PSEUDOPHAKIC MACULA-OFF RHEGMATOGENOUS RETINAL DETACHMENTS

PURPOSE

To assess the long-term visual recovery in uncomplicated macula-off pseudophakic rhegmatogenous retinal detachment treated with pars plana vitrectomy and gas tamponade in the absence of other visual comorbidities.

METHODS

Single-center retrospective longitudinal study on eyes with macula-off pseudophakic rhegmatogenous retinal detachment successfully treated with pars plana vitrectomy between 2011 and 2020 and with at least 2 follow-ups (FU), first gas-free FU (first-FU) and a final-FU, were included. Patients with subsequent ocular surgery or comorbidities affecting best-corrected visual acuity were excluded. The duration between operation date and final-FU was calculated (total days FU) and split into total days quintiles-1: ≤57, 2: >57 and ≤77, 3: >77 and ≤152, 4: >152 and ≤508, and 5: >508 days. Multivariable regression was performed with logMAR gain between the first and the final-FU as the dependent variable.

RESULTS

In 209 eyes, the authors report association with increase of logMAR gain between the first and the final-FU, with reducing clock hours of pseudophakic rhegmatogenous retinal detachment ( P = 0.041) and relative to the total days Quintile 1. Mean (SD) logMAR gain between the first and the final-FU was 0.02 (0.07) in the first quintile, increasing to 0.14 (0.13) ( P < 0.001) by the fifth quintile on multivariable regression. For patients not achieving 0.30 logMAR at the first-FU, this was attained at the final-FU with a sensitivity of 51.9% and specificity of 95.5% at a cut off ≤0.58 logMAR at the first-FU (area under the curve 0.756 [95% confidence interval 0.664-0.848], P < 0.001).

CONCLUSION

The authors report a significant time-dependent visual improvement after uncomplicated pars plana vitrectomy with gas tamponade for macula-off pseudophakic rhegmatogenous retinal detachment without visual confounders and provide important quantitative data for counselling patients with macula-off repair.

Transcriptomic Analysis of Retinal Gene in Experimental Retinal Detachment Rats and Exploration of S100A9 and TLR4 in Human Vitreous

PURPOSE

To screen for the differentially expressed genes in experimental retinal detachment rats, and to explore the expression of S100 calcium-binding protein A9 and Toll-like receptor 4 in the vitreous of rhegmatogenous retinal detachment patients.

METHODS

Three rats of experimental retinal detachment and three normal rats were enrolled in the study. Transcriptomics (RNAseq) sequencing technology was used to screen differentially expressed genes in the retinas of the experimental retinal detachment group and the normal group. The selected differentially expressed genes for gene ontology and Kyoto Encyclopedia of Genes and Genomes functional enrichment analysis were performed. In addition, the vitreous of 15 patients with rhegmatogenous retinal detachment and six patients with the control group were collected. The expressions of S100 calcium-binding protein A9 and Toll-like receptor 4 were detected by Elisa, and the differences in expression levels were analyzed statistically.

RESULTS

A total of 198 differentially expressed genes were screened by RNAseq sequencing, including 118 upregulated genes and 80 downregulated genes. Kyoto Encyclopedia of Genes and Genomes analysis confirmed that the most enriched pathway was the mitogen-activated protein kinase signaling pathway. Compared to the normal group, the expressions of suppressor of cytokine signaling-3, Storkhead box-2, S100 calcium-binding protein A9, Spi-1 proto-oncogene, phosphodiesterase 1B, and kinesin-light chain 1 mRNA in the retinas of the experimental retinal detachment rats were up-regulated, and the expressions of Max interacting protein 1 and the voltage-gated sodium 1 were down-regulated. Compared to the control group, the expressions of S100 calcium-binding protein A9 and Toll-like receptor 4 were upregulated by Elisa in the vitreous humor of rhegmatogenous retinal detachment patients with a statistically significant difference (p all <.05).

CONCLUSION

The differentially expressed genes of experimental retinal detachment rats were suppressor of cytokine signaling-3, Storkhead box-2, S100 calcium-binding protein A9, Spi-1 proto-oncogene, phosphodiesterase 1B, kinesin-light chain 1, Max interacting protein 1, voltage-gated sodium 1, etc. The differences of S100 calcium-binding protein A9 and Toll-like receptor 4 expressions between the rhegmatogenous retinal detachment patients and the control group were statistically significant, indicating that they may play a potential role in the inflammatory process of rhegmatogenous retinal detachment.

The effect of sex and laterality on the phenotype of primary rhegmatogenous retinal detachment

BACKGROUND

To assess the effect of sex and laterality on clinical features of primary rhegmatogenous retinal detachment (RRD).

METHOD

This study is a retrospective analysis of data prospectively collected. We extracted data from two online datasets over a 7-year period of patients older than 16 years who had undergone surgery for primary RRD. Data on baseline characteristics were analyzed to compare males versus females, and right versus left eyes.

RESULTS

Of 8133 eyes analyzed, 4342 (53.4%) were right. The overall male predominance (63.7%) was more marked in the age range 50-69 years. Men were more commonly pseudophakic and presented more frequently with baseline posterior vitreous detachment (PVD). Female sex was significantly associated with baseline myopia, retinal holes as causative retinal break, and isolated inferior RD. Men had more frequent foveal involvement, greater RRD extent, greater numbers and larger sized retinal tears including dialysis and giant retinal tears. Regarding laterality, foveal involvement, larger retinal breaks, isolated temporal RD and temporal retinal breaks were more common in right eyes, whereas left eyes were more myopic at baseline and presented more frequently with isolated nasal RD and nasal retinal breaks.

CONCLUSIONS

This study confirmed the predominance of male sex and right laterality in RRD. Sex and laterality were associated with multiple presenting features of RRD including extent, break distribution, number, size and type, as well as RD distribution.

The impact of 360-laser barricade on outcomes of vitrectomy for pseudophakic retinal detachment; The Manchester Pseudophakic Retinal Detachment Study

PURPOSE

To investigate the anatomical and functional outcomes and specifically, the effect of 360-degree barrier-laser, in pars plana vitrectomy (PPV) for primary pseudophakic rhegmatogenous retinal detachment (PRD).

METHODS

We conducted a single-centre retrospective, continuous and comparative study on eyes that had undergone PPV with focal-retinopexy (laser or cryotherapy) versus 360-laser for PRD repair between 2011-2020 at a single tertiary vitreoretinal centre in the UK. Primary outcomes were single surgery anatomical success (SSAS) rate and final postoperative visual acuity (VA). Multivariable regression covariates for primary re-detachment included age, gender, onset-of-detachment, pre-operative VA, ocular co-morbidities, macula-status, majority inferior (vs superior) PRD, number-of-tears and PRD extent (in clock-hours), 360-laser barricade, and perfluorocarbon liquid (PFCL) use. For VA gain, primary re-detachment was added as a covariate.

RESULTS

We included 467 eyes with a mean follow-up of 388 (161) days. The SSAS was 444/467 (95.1%) overall, and 351/370 (94.9%) and 93/97 (95.9%) in focal-retinopexy and 360-laser groups, respectively (p = 0.798). Compared to the focal-retinopexy group, the 360-laser group had significantly worse post-operative VA but similar logMAR gain (p = 0.812). A multivariable binary logistic regression found that only PFCL use was linked with increased primary re-detachment (OR:5.32 [p = 0.048]) and 360-laser did not contribute to increased SSAS. A multivariable linear regression analysis showed that poor logMAR gain was significantly associated with better pre-operative logMAR, ocular co-morbidities, greater PRD extent, use of 360-laser and primary re-detachment. However, when excluding macula-off RD (n = 211), 360-laser was no longer significant (p = 0.088).

CONCLUSIONS

Prophylactic 360-laser does not seem to impact on SSAS and functional outcomes following PPV for primary PRD.

Stratifying the risk of re-detachment: variables associated with outcome of vitrectomy for rhegmatogenous retinal detachment in a large UK cohort study

INTRODUCTION

To identify variables associated with primary anatomical outcome following vitrectomy and internal tamponade for rhegmatogenous retinal detachment (RD).

METHODS

A retrospective analysis of prospectively collected data, using a database of RD treated with vitrectomy and internal tamponade. Collected data complied with the RCOphth Retinal Detachment Dataset. The main outcome measure was anatomical failure within six months of surgery.

RESULTS

There were 6377 vitrectomies. 869 eyes were excluded, either because no outcome was recorded, or inadequate follow up, leaving 5508 operations for analysis. 63.9% of patients were male, and the median age was 62. Primary anatomical failure occurred in 13.9%. On multivariate analysis, the following were associated with increased risk of failure: age <45, or >79, inferior retinal breaks, total detachment, one quadrant or greater inferior detachment, low density silicone oil, and presence of proliferative vitreoretinopathy. C2F6 tamponade, cryotherapy, and 25 G vitrectomy, were associated with reduced risk of failure. The area under the receiver operator curve was 71.7%. According to this model, 54.3% of RD are at low risk (<10%), 35.6% are at moderate risk (10-25%), and 10.1% are at high risk (>25%) of failure.

CONCLUSIONS

Previous attempts to identify high risk RD have been limited by small numbers, the inclusion of both scleral buckling and vitrectomy, or by excluding some types of RD. This study examined outcomes in unselected RD, treated by vitrectomy. Identification of the variables associated with anatomical outcome after RD surgery enables accurate risk stratification, which is valuable for patient counselling and selection, and for future clinical trials.

The effect of age on phenotype of primary rhegmatogenous retinal detachment

BACKGROUND

To evaluate the influence of age on the clinical characteristics of primary rhegmatogenous retinal detachments (RRD).

METHODS

We conducted a retrospective review of a prospectively collected dataset. Data regarding adult patients (aged 16-100 years) who had undergone primary RRD repair, were extracted from two online databases. Baseline demographics, preoperative clinical characteristics and surgical management details were collected. Age-based groups (16-30, 30-39, 40-49, 50-59, 60-69, 70-79, ≥80) were compared using univariate analysis, with multivariate testing for interaction of age with sex, laterality and pseudophakia.

RESULTS

In total, 8,133 eyes were analysed, of which the majority (59%) were in the 50-69 age-range peaking at 60, with a male predominance (64%). Myopia was significantly more frequent in patients aged <50 years. The presence of posterior vitreous detachment increased up to 50 years, then remained >95%. Foveal involvement, grade C proliferative vitreoretinopathy, total RD and greater RD extent were more common and progressively increased after 60 years, with worsening visual acuity. Isolated superior RRDs became more prevalent with age reaching a plateau in the age-range 50-69, before reducing again; conversely, isolated inferior RRDs were commoner in those <30, with a minimum in the 70-79 age-range. The incidence of fellow-eye RRD decreased linearly with age.

CONCLUSIONS

Age appeared a key variable in RRD phenotype influencing a wide range of RRD characteristics. The higher incidence of myopia, PVD absent and bilateral RRD in patients <40 years and the significant phenotypical differences in the under 40 and over 50 age-groups highlight that there are several discrete forms of RRD.

The Short-Term Results of Autologous Platelet-Rich Plasma as an Adjuvant to Re-Intervention in the Treatment of Refractory Full-Thickness Macular Holes

The purpose of this study was to investigate the short-term efficacy and safety of autologous platelet-rich plasma (a-PRP) as an adjuvant to revisional vitrectomy for refractory full-thickness macular holes (rFTMHs). We conducted a prospective, non-randomized interventional study including patients with rFTMH after a pars plana vitrectomy (PPV) with internal limiting membrane peeling and gas tamponade. We included 28 eyes from 27 patients with rFTMHs: 12 rFTMHs in highly myopic eyes (axial length greater than 26.5 mm or a refractive error greater than -6D or both); 12 large rFTMHs (minimum hole width > 400 μm); and 4 rFTMHs secondary to the optic disc pit. All patients underwent 25-G PPV with a-PRP, a median time of 3.5 ± 1.8 months after the primary repair. At the six-month follow-up, the overall rFTMH closure rate was 92.9%, distributed as follows: 11 out of 12 eyes (91.7%) in the highly myopic group, 11 out of 12 eyes (91.7%) in the large rFTMH group, and 4 out of 4 eyes (100%) in the optic disc pit group. Median best-corrected visual acuity significantly improved in all groups, in particular from 1.00 (interquartile range: 0.85 to 1.30) to 0.70 (0.40 to 0.85) LogMAR in the highly myopic group (p = 0.016), from 0.90 (0.70 to 1.49) to 0.40 (0.35 to 0.70) LogMAR in the large rFTMH group (p = 0.005), and from 0.90 (0.75 to 1.00) to 0.50 (0.28 to 0.65) LogMAR in the optic disc pit group. No intraoperative or postoperative complications were reported. In conclusion, a-PRP can be an effective adjuvant to PPV in the management of rFTMHs.

Artificial intelligence using deep learning to predict the anatomical outcome of rhegmatogenous retinal detachment surgery: a pilot study

PURPOSE

To develop and evaluate an automated deep learning model to predict the anatomical outcome of rhegmatogenous retinal detachment (RRD) surgery.

METHODS

Six thousand six hundred and sixty-one digital images of RRD treated by vitrectomy and internal tamponade were collected from the British and Eire Association of Vitreoretinal Surgeons database. Each image was classified as a primary surgical success or a primary surgical failure. The synthetic minority over-sampling technique was used to address class imbalance. We adopted the state-of-the-art deep convolutional neural network architecture Inception v3 to train, validate, and test deep learning models to predict the anatomical outcome of RRD surgery. The area under the curve (AUC), sensitivity, and specificity for predicting the outcome of RRD surgery was calculated for the best predictive deep learning model.

RESULTS

The deep learning model was able to predict the anatomical outcome of RRD surgery with an AUC of 0.94, with a corresponding sensitivity of 73.3% and a specificity of 96%.

CONCLUSION

A deep learning model is capable of accurately predicting the anatomical outcome of RRD surgery. This fully automated model has potential application in surgical care of patients with RRD.

Postoperative positioning regimens in adults who undergo retinal detachment repair: A systematic review

Little is known about the comparative benefit of different positioning regimens in rhegmatogenous retinal detachment (RRD) repair. We compared outcomes of different postoperative posturing regimens following pars plana vitrectomy (PPV). MEDLINE, EMBASE, and Cochrane CENTRAL were searched from 2000 to February 2022 for original studies that compared at least 2 postoperative posturing regimens in adults who underwent PPV for RRD. Seven comparative studies and 703 eyes were included. There were no differences in final visual acuity between posturing regimens. Single-procedure reattachment rates were higher with alternative positioning compared to prone positioning in patients with inferior breaks. Prone and alternative positioning were associated with similar risks of complications. In contrast, prone posturing had a higher risk of neck pain and intraocular pressure elevation than support-the-break, which had a greater risk of retinal displacement, retinal folds, and binocular diplopia. Immediate prone positioning was superior to delayed prone for the risk of retinal displacement. The present review shows that prone positioning was associated with a lower reattachment rate than alternative positioning. There were trade-offs in complications between prone and support-the-break positioning. Retinal displacement could be mitigated when prone positioning is maintained immediately after surgery.

The Genetic Architecture of Non-Syndromic Rhegmatogenous Retinal Detachment

Rhegmatogenous retinal detachment (RRD) is the most common form of retinal detachment (RD), affecting 1 in 10,000 patients per year. The condition has significant ocular morbidity, with a sizeable proportion of patients obtaining poor visual outcomes. Despite this, the genetics underpinning Idiopathic Retinal Detachment (IRD) remain poorly understood; this is likely due to small sample sizes in relevant studies. The majority of research pertains to the well-characterised Mende lian syndromes, such as Sticklers and Wagners, associated with RRD. Nevertheless, in recent years, there has been an increasing body of literature identifying the common genetic mutations and mechanisms associated with IRD. Several recent Genomic Wide Association Studies (GWAS) studies have identified a number of genetic loci related to the development of IRD. Our review aims to provide an up-to-date summary of the significant genetic mechanisms and associations of Idiopathic RRD.

The Scottish RD survey 10 years on: the increasing incidence of retinal detachments

BACKGROUND

The Scottish RD Survey reported an incidence of 12.05/100,000/yr in 2009. Data published from Denmark recently confirmed a 50% increase in RD presentations over the last 16 years. We set out to repeat the Scottish RD survey to determine if a similar trend has been observed in Scotland.

METHODS

All 16 Scottish VR surgeons, who make up the collaboration of Scottish VR Surgeons (SCVRs) were asked to prospectively record all primary RDs presenting from 12th August 2019 to 11th August 2020. For consistency, the case definitions were the same as for the 2009 Scottish RD Survey. Basic demographic and clinical features were recorded. Age specific incidence was calculated from mid-year population estimates for 2019 obtained from the National Records of Scotland.

RESULTS

There were 875 RRDs recorded, which gives an updated incidence of 16.02/100,000/year in Scotland. 62.8% occurred in males and the greatest increases were seen in males aged 50-59 (p = 0.0094), 60-69 (p = 0.0395) and females aged 40-49 (p = 0.0312) and 50-59 (p = 0.0024). The proportion of pseudophakic RRDs in this study is 29.4% (253/860). Compared to the 21.6% in the 2010 study, this represents a 28% increase (χ² = 11.03, p = 0.0009). The proportion of macula-off RRDs remained generally stable at 58%.

CONCLUSION

Our study confirms that RRD is becoming more common in the UK, reflecting almost identical findings from Denmark. This trend is in part due to increasing myopia, increasing pseudophakia, and possibly other factors. This should be considered when planning VR services and allocating resources in the future.

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.
