Mean Change In Best-corrected Visual Acuity Research Articles

Aqueous humour interleukin-6 and vision outcomes with anti-vascular endothelial growth factor therapy.

This analysis evaluated aqueous humour (AH) interleukin (IL)-6 concentrations and the association between AH IL-6 and visual outcomes in patients with neovascular age-related macular degeneration (nAMD) or diabetic macular oedema (DMO) receiving anti-vascular endothelial growth factor (VEGF) monotherapy. Post hoc analysis of the multicentre, double-masked, randomised HARBOR (NCT00891735) and READ-3 (NCT01077401) trials. HARBOR enrolled treatment-naïve nAMD patients. READ-3 enrolled treatment-naïve/previously treated DMO patients. HARBOR patients received ranibizumab 0.5 or 2.0 mg monthly or as needed; AH samples were collected at month 2, after two previous intravitreal injections. READ-3 patients received ranibizumab 0.5 or 2.0 mg as needed; AH samples were collected at baseline and months 3, 6, 9, and 12. association between AH IL-6 concentrations and month 24 best-corrected visual acuity (BCVA). In both trials (HARBOR, N = 36; READ-3, N = 137), patients with higher AH IL-6 concentrations had worse visual outcomes. HARBOR patients with low AH IL-6 concentrations at month 2 had a mean (95% CI) BCVA change at month 24 of +2.9 (-2.6, 8.3) letters, whereas patients with high AH concentrations had a mean (95% CI) BCVA change of -9.0 (-22.7, 4.7) letters. READ-3 patients with low AH concentrations at baseline had a mean (95% CI) BCVA change at month 12 of +9.3 (7.4, 11.3) letters, whereas patients with high AH concentrations had a mean (95% CI) BCVA change of +5.6 (2.2, 9.1) letters. Higher IL-6 AH concentrations may predict suboptimal visual responses to anti-VEGF monotherapy in patients with nAMD/DMO.

Comparative Study on Anti-VEGF in Wet Age-Related Macular Degeneration in the Setting Based on Lean Methodology from the Bari Intravitreal Injection Registry (BIVIR).

Optimizing treatment protocols for wet age-related macular degeneration (wAMD) is an ongoing challenge, as it involves a delicate balance between achieving therapeutic efficacy and minimizing invasive procedures' frequency. This study aimed to apply the Lean methodology and evaluate the effectiveness of this new setting on intravitreal therapy for wAMD, employing different anti-vascular endothelial growth factors (VEGF) drugs (bevacizumab, brolucizumab, aflibercept, ranibizumab), drawing data from the Bari Intravitreal Injections Registry (BIVIR). This was a retrospective, monocentric, nonrandomized, comparative study. Lean methodology was employed to design the new setting and the BIVIR collected information from electronic medical records. Clinical data of four groups, stratified based on the first-line anti-VEGF agents used, were compared. Best-corrected visual acuity (BCVA) and central retinal thickness (CRT) changes were compared between the four groups at 3 and 12 months. Out of 4990 eyes and 41,323 intravitreal injections (IVs) recorded in BIVIR, 1421 eyes of 1182 patients were included. The mean number of IVs in first year was 6.1 ± 2.5, with no significant differences among the four subgroups. The mean change in BCVA was + 6.2 letters [95% confidence interval (CI) 5.6-6.8] after two IVs, and + 5.9 (95% CI 5.1-6.8) letters after three IVs; at three months, brolucizumab was associated with a greater mean increase in BCVA than bevacizumab (p = 0.050); aflibercept (p = 0.044) and ranibizumab p = 0.047). At the 1-year follow-up, the mean change was + 6.3 letters (95% CI 5.4-7.2), brolucizumab and ranibizumab were associated with a superior improvement in BCVA compared to aflibercept (p = 0.033). Regarding the CRT, a significant reduction was observed in the subgroup treated with brolucizumab at the 3-month follow-up, compared to bevacizumab (p = 0.003), aflibercept (p = 0.015), and ranibizumab (p < 0.001); Aflibercept exhibited a superior effect than ranibizumab (p = 0.001). At 1-year follow-up, aflibercept resulted in a more significant reduction of macular thickness compared to ranibizumab (p = 0.016) while no significant differences were observed among the other drugs. Our practical experience showed the effectiveness of the new setting in the treatment of wAMD. This comparative study at 1year suggested a predominant brolucizumab efficacy on functional outcomes. In addition, brolucizumab and aflibercept appeared to have similar efficacy in fluid control.

Internal limiting membrane peeling in rhegmatogenous retinal detachment: A meta-analysis.

To determine whether pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling for rhegmatogenous retinal detachment (RRD) could get better functional and anatomical outcomes. A comprehensive literature search was performed to find relevant studies. A meta-analysis was conducted by comparing the weighted mean differences (WMD) in the mean change of best corrected visual acuity (BCVA) from baseline and calculating the odd ratios (OR) for rates of epiretinal membrane (ERM) formation and recurrence of retinal detachment (RD). Fourteen studies were selected, including 2259 eyes (825 eyes in the ILM peeling group and 1434 eyes in the non-ILM peeling group). There was no significant difference in terms of mean change in BCVA from baseline and the rate of RD recurrence (WMD = 0.02, 95% CI, -0.20 to 0.24, P = 0.86, and OR = 0.55, 95% CI, 0.24 to 1.26, P = 0.16), but ILM peeling was associated with a significantly lower frequency of postoperative ERM formation (OR = 0.13, 95% CI, 0.06 to 0.26, P<0.00001). Similar results were obtained in a sub-analysis based on macula-off RRD. ILM peeling results in similar BCVA, with same rate of RD recurrence, but lower rate of postoperative ERM development. ILM peeling could be considered in selected cases with risk factors that are likely to develop an ERM.

Visual Outcome and Fluid Changes Between Eyes With Polypoidal Choroidal Vasculopathy Receiving Biosimilar CKD-701 or Reference Ranibizumab Therapy: A Post Hoc Analysis of a Phase 3 Randomized Clinical Trial

Purpose To compare the visual outcome and fluid features of a proposed biosimilar, CKD-701, versus the reference ranibizumab in eyes with polypoidal choroidal vasculopathy (PCV). Methods This was a post hoc analysis of a phase 3 randomized clinical trial assessing the efficacy and safety of CKD-701 and ranibizumab. A total of 73 PCV eyes were assigned randomly to either CKD-701 (36 eyes) or ranibizumab (37 eyes). The mean changes in best-corrected visual acuity (BCVA), central retinal thickness (CRT), pigment epithelial detachment (PED) volume, and fluid features were compared. Results After three loading injections, the mean change in BCVA (letters) was +7.50 in the CKD-701 group and +6.32 in the ranibizumab group (p = .447). The changes in CRT and PED volume of the CKD-701 group (−107.25 ± 102.66 μm and −0.22 ± 0.46 mm3) were similar to those of the ranibizumab group (−96.78 ± 105.00 μm and −0.23 ± 0.54 mm3) (p = .668 and p = .943, respectively). Proportions of eyes with subretinal, intraretinal and sub-retinal pigment epithelium (RPE) fluids after three loading injections were not different between CKD-701 group (33.3%, 13.9% and 42.9%) and ranibizumab group (51.4%, 16.2% and 40.0%) (p = .071, p = 1.000 and p = .808). The visual and anatomical changes were similar between two groups at month 6 and 12 (all, p > .05). Conclusion Biosimilar CKD-701 monotherapy resulted in comparable visual and anatomical changes to those achieved with reference ranibizumab in PCV eyes.

Intravitreal aflibercept 8 mg in neovascular age-related macular degeneration (PULSAR): 48-week results from a randomised, double-masked, non-inferiority, phase 3 trial

Intravitreal aflibercept 8 mg could improve treatment outcomes and provide sustained disease control in patients with neovascular age-related macular degeneration (nAMD), with extended dosing compared with aflibercept 2 mg. PULSAR is a phase 3, randomised, three-group, double-masked, non-inferiority, 96-week trial conducted across 223 sites worldwide. Adults with nAMD were randomised 1:1:1 to aflibercept 8 mg every 12 weeks (8q12), aflibercept 8 mg every 16 weeks (8q16), or aflibercept 2 mg every 8 weeks (2q8), following three initial monthly doses in all groups. From week 16, patients in the aflibercept 8 mg groups had their dosing interval shortened if pre-specified dose regimen modification criteria denoting disease activity were met. The primary endpoint was change from baseline in best-corrected visual acuity (BCVA) at week 48. All patients with at least one dose of study treatment were included in the efficacy and safety analyses. This trial is registered with ClinicalTrials.gov (NCT04423718) and is ongoing. Of 1011 patients randomised to aflibercept 8q12 (n=336), 8q16 (n=338), or 2q8 (n=337) between Aug 11, 2020, and July 30, 2021, 1009 patients received study treatment (aflibercept 8q12 n=335; aflibercept 8q16 n=338; and aflibercept 2q8 n=336). Aflibercept 8q12 and 8q16 showed non-inferior BCVA gains versus aflibercept 2q8 (mean BCVA change from baseline +6·7 [SD 12·6] and +6·2 [11·7] vs +7·6 [12·2] letters). The least squares mean differences between aflibercept 8q12 versus 2q8 and 8q16 versus 2q8, respectively, were -0·97 (95% CI -2·87 to 0·92) and -1·14 (-2·97 to 0·69) letters (non-inferiority margin at 4 letters). The incidence of ocular adverse events in the study eye was similar across groups (aflibercept 8q12 n=129 [39%]; aflibercept 8q16 n=127 [38%]; and aflibercept 2q8 n=130 [39%]). Aflibercept 8 mg showed efficacy and safety with extended dosing intervals, which has the potential to improve the management of patients with nAMD. Bayer AG and Regeneron Pharmaceuticals.

REDUCING TREATMENT BURDEN FOR AGE-RELATED MACULAR DEGENERATION PATIENTS: A SYSTEMATIC REVIEW OF RANIBIZUMAB PORT DELIVERY SYSTEM

Introduction and Objective: Ranibizumab port delivery system (PDS) is a newly developed method that provides a continuous, long-term supply of ranibizumab into the vitreous, reducing the burden of monthly intravitreal injection visits for neovascular age-related macular degeneration (nAMD) patients. This review aims to evaluate the efficacy and safety of ranibizumab PDS in nAMD. &#x0D; Methods: An extensive literature search was performed on 4 online databases: PubMed, Cochrane, ProQuest, and ScienceDirect. The inclusion criteria are human studies comparing ranibizumab port delivery system and intravitreal ranibizumab, English language, with full-text journal available. The main outcome measurements are best-corrected visual acuity (BCVA) in Early Treatment Diabetic Retinopathy Study (ETDRS) letters, central foveal thickness (CFT), and adverse events.&#x0D; Result: Two randomized controlled trials (RCTs) with a total of 635 adults were evaluated. At week 96, ranibizumab PDS reported observed mean BCVA changes from baseline (-1.0; +4.2; ETDRS letters) compared to monthly intravitreal ranibizumab (-1.1; +6.1; ETDRS letters). However, there was an increase in mean CFT changes from baseline (+9.9; -15.3 vs ?1.3; -21.3, µm) and more severe adverse events frequency (22; 4 vs 4; 0) with ranibizumab PDS versus monthly intravitreal ranibizumab, respectively. &#x0D; Conclusion: Ranibizumab PDS showed comparable visual outcomes to intravitreal ranibizumab while demonstrating marginally inferior anatomical outcomes and higher incidence of severe adverse effects. Despite this, with fewer treatment visits required for up to 24 weeks, ranibizumab PDS can potentially reduce the treatment burden in nAMD patients with poor compliance. Further studies are needed to provide better patient eligibility guidelines and recommendations for adverse event management of ranibizumab PDS.

XTEND: Two-Year Results from a Global Observational Study Investigating Proactive Dosing of Intravitreal Aflibercept in Neovascular Age-Related Macular Degeneration.

XTEND (NCT03939767) is a multicenter, observational, prospective study of patients with treatment-naïve neovascular age-related macular degeneration (nAMD) in routine clinical practice. The study aims to examine treatment outcomes of proactive intravitreal aflibercept (IVT-AFL) treatment regimens (fixed dosing or treat-and-extend) according to local marketing labels. Study eyes received IVT-AFL injections as per the local label. The mean changes in best-corrected visual acuity (BCVA) and central subfield thickness (CST) from baseline to month (M) 12 and M24 were measured and stratified by baseline factors. Treatment exposure and safety data were evaluated. Statistical analysis was descriptive. Overall, 1466 patients from 17 countries were treated. For the overall population, the mean ± standard deviation (SD) age was 78.7 ± 8.5 (range 50-100)years, and 891 patients (60.8%) were female. The mean ± SD baseline BCVA was 54.3 ± 20.3 letters and CST was 374 ± 126µm. At M12 and M24, mean (95% confidence interval [CI]) BCVA change was + 4.3 (3.4, 5.3) and + 2.3 (1.3, 3.3) letters, respectively. Mean (95% CI) CST was - 106 (- 114, - 99) μm and - 109 (- 117, - 102) μm at M12 and M24, respectively. At M24, 41.5% of patients had a BCVA ≥ 70 letters. Patients received a mean ± SD of 7.7 ± 2.7 injections by M12 and 10.8 ± 5.0 injections by M24 (3.1 injections between M12 and M24). Adverse events were consistent with the known safety profile of IVT-AFL. The 24-month results indicate that, in routine clinical practice, a proactive IVT-AFL regimen achieves functional improvements in patients with treatment-naïve nAMD. The proportion of patients achieving ≥ 70 letters at M24 increased, and patients with baseline BCVA ≥ 70 letters maintained vision regardless of the followed IVT-AFL label. ClinicalTrials.gov identifier: NCT03939767. A video abstract is available for this article. Supplementary file2 (MP4 364624 KB).

Outcomes of Pars Plana Vitrectomy With Membrane Peel for Lamellar Macular Holes and Related Conditions Using a New Optical Coherence Tomography Consensus Definition.

Purpose: To characterize the change in visual acuity (VA) in eyes treated with vitrectomy using the 2020 international consensus-based optical coherence tomography (OCT) definition of lamellar macular hole (LMH), macular pseudohole (MPH), and epiretinal membrane with foveoschisis (ERMF). Methods: A retrospective chart review was performed from 2000 to 2022 of patients who had vitrectomy for symptomatic decreased VA from LMH, MPH, or ERMF performed by the same surgeon at a community hospital. Preoperative spectral domain (SD-OCT) was reviewed to classify patients using the consensus guidelines. Primary outcomes were the mean change in best-corrected VA at 3 months, 1 year, and the final postoperative examination. Results: Fifty-one patients were included, 30 with LMH, 14 with MPH, and 7 with ERMF. The VA was 20/63 at baseline, 20/62 (P = .79) 3 months postoperatively, 20/40 (P = .003) at 1 year, and 20/52 (P = .10) at the final examination for LMH; 20/64, 20/50 (P = .16), 20/40 (P = .040), and 20/40 (P = .02), respectively, for MPH; and 20/53, 20/50 (P = .42), 20/30 (P = .03), and 20/38 (P = .04), respectively, for ERMF. Subgroup analysis showed that eyes with LMH without ellipsoid zone (EZ) disruption on SD-OCT improved from 20/57 at baseline to 20/39 (P = .01) at the final examination. Conclusions: There was no significant improvement in VA at the final postvitrectomy examination in eyes with LMH, while there was significant improvement in eyes with MPH and ERMF. This supports surgery in selected eyes with MPH and ERMF but possibly not in eyes with LMH, unless OCT shows no EZ disruption.

Faricimab Treat-and-Extend for Diabetic Macular Edema: Two-Year Results from the Randomized Phase 3 YOSEMITE and RHINE Trials

PurposeTo evaluate the 2-year efficacy, durability, and safety of dual angiopoietin-2/vascular endothelial growth factor (VEGF)-A pathway inhibition with intravitreal faricimab according to a personalized treat-and-extend–based regimen (T&E) with up to every-16-week (Q16W) dosing in the YOSEMITE/RHINE (NCT03622580/NCT03622593) phase 3 trials of diabetic macular edema (DME). DesignRandomized, double-masked, noninferiority phase 3 trials. ParticipantsAdults with visual acuity loss due to center-involving DME. MethodsPatients were randomized 1:1:1 to faricimab 6.0 mg Q8W, faricimab 6.0 mg T&E (previously referred to as personalized treatment interval), or aflibercept 2.0 mg Q8W. The T&E up to Q16W dosing regimen was based on central subfield thickness (CST) and best-corrected visual acuity (BCVA) change. Main Outcome MeasuresIncluded changes from baseline in BCVA and CST, number of injections, durability, absence of fluid, and safety through week 100. ResultsIn YOSEMITE/RHINE (N=940/951), noninferior year 1 visual acuity gains were maintained through year 2; mean BCVA change from baseline at 2 years (weeks 92/96/100 average) with faricimab Q8W (YOSEMITE/RHINE, +10.7/+10.9 letters) or T&E (+10.7/+10.1 letters) were comparable with aflibercept Q8W (+11.4/+9.4 letters). The median number of study drug injections was lower with faricimab T&E (YOSEMITE/RHINE, 10/11 injections) versus faricimab Q8W (15 injections) and aflibercept Q8W (14 injections) across both trials during the entire study. In the faricimab T&E arms, durability was further improved during year 2, with >60% of patients on Q16W dosing and ∼80% on ≥Q12W dosing at week 96. Almost 80% of patients who achieved Q16W dosing at week 52 maintained Q16W dosing without an interval reduction through week 96. Mean CST reductions were greater, and more patients achieved absence of DME (CST <325μm) and absence of intraretinal fluid with faricimab Q8W or T&E versus aflibercept Q8W through year 2. Overall, faricimab was well tolerated, with a safety profile comparable to aflibercept. ConclusionsClinically meaningful visual acuity gains from baseline, anatomic improvements, and extended durability with intravitreal faricimab up to Q16W were maintained through year 2. Faricimab given as a personalized T&E–based dosing regimen supports the role of dual angiopoietin-2/VEGF-A inhibition to promote vascular stability and provide durable efficacy for patients with DME.

The effect of nondamaging subthreshold laser therapy in patients with chronic central serous chorioretinopathy.

To evaluate the efficacy of nondamaging subthreshold laser therapy in Korean patients with chronic central serous chorioretinopathy (cCSC). This retrospective interventional case series included 31 patients (31 eyes) with cCSC who underwent nondamaging laser therapy using Endpoint Management (EpM) software. Since a barely visible burn of the test spot was defined as 100% pulse energy, 30% pulse energy with a 200-μm spot was titrated to treat the macular area based on EpM settings. A 30% pulse laser with a spacing of 0.25-beam diameter was applied to cover the macular area where hyperfluorescent leaks were observed on fluorescein angiography. Changes in central macular thickness (CMT), subretinal fluid (SRF) height, subfoveal choroidal thickness (SCT), and logarithm of the minimum angle of resolution (logMAR) best-corrected visual acuity (BCVA) were measured at baseline and after 3 and 6months. If the subretinal fluid persisted for 3months, retreatment was performed. At 6months post-treatment, the complete SRF resolution rate was 48.39% (15/31 eyes), and the partial SRF resolution rate was 12.90% (4/31 eyes). The change in mean BCVA (logMAR) was not significant (0.31 ± 0.29 at the baseline and 0.31 ± 0.40 at month 6) (p = 0.943). At the baseline, the mean CMT (μm) decreased from 350.74 ± 112.76 at baseline to 239.71 ± 130.25 at month 6 (p < 0.001), and the mean SRF height (μm) decreased from 193.16 ± 90.69 at baseline to 70.58 ± 100.00 at month 6 (p < 0.001). However, the change in SCT was not statistically significant (p = 0.516). In 15 patients who were retreated at month 3, the mean SRF height (μm) decreased significantly from 144.67 ± 74.01 at month 3 to 77.13 ± 63.77 at month 6 (p = 0.002). No side effects associated with laser therapy were observed during the 6-month follow-up. Nondamaging laser therapy with a modified macular treatment was effective in reducing CMT and SRF and showed favorable visual and anatomical outcomes in patients with cCSC.

Real-world outcomes of intravitreal bevacizumab treat-and-extend for cystoid macular oedema secondary to central retinal vein occlusion.

The purpose of this study was to report the real-world treatment outcomes using a treat-and-extend intravitreal bevacizumab protocol in cystoid macular oedema (CMO) secondary to central retinal vein occlusion (CRVO). We conducted a retrospective case series of consecutive adult patients with CMO secondary to CRVO who presented between 1st January 2019 and 31st December 2021. All included patients were treated with bevacizumab using a treat-and-extend protocol, were followed up for a minimum of 6months and had a clinical examination including best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) at every visit. The primary outcome measure was mean change in BCVA. Thirty-three eyes of 33 patients were included in the study. The mean change in BCVA from baseline was + 24.5 (Median 18, SD 21.5) letters, with a mean follow-up duration of 18.5 (SD 8.9) months. The mean number of injections was 9.5 (SD 1.9) in year 1 and 7.8 (SD 2.8) in year 2. 87.9% of patients were still requiring active treatment, with a maximum interval achieved of 4-weekly in 18.2%, 6-weekly in 42.4%, 8-weekly in 6.1%, 10-weekly in 15.2%, and 12-weekly in 6.1%. The mean maximum interval achieved of those requiring ongoing treatment was 6.8 (SD 2.4) weeks. Multiple regression analyses showed that a higher baseline BCVA was negatively associated with mean visual acuity gain (P < 0.001) and positively associated with final BCVA (P < 0.001). The use of intravitreal bevacizumab in a treat-and-extend regimen is effective in treating CMO secondary to CRVO, in a real-world setting.

Comparative Efficacy, Durability and Safety of Faricimab in the Treatment of Diabetic Macular Edema: A Systematic Literature Review and Network Meta-Analysis.

A systematic literature review (SLR) and network meta-analysis (NMA) were conducted to evaluate the comparative efficacy, durability and safety of faricimab, used in a Treat & Extend (T&E) regime with intervals up to every 16weeks (Q16W), relative to other therapies currently in use for treatment of diabetic macular oedema (DME). Of particular interest were anti-vascular endothelial growth factor (VEGF) therapies applied in flexible dosing regimens such as Pro re nata (PRN) and T&E, which are the mainstay in clinical practice. An SLR identifying randomised controlled trials (RCTs) published before August 2021 was conducted, followed by a Bayesian NMA comparing faricimab T&E treatment to aflibercept, ranibizumab, bevacizumab, dexamethasone and laser therapy. Outcomes included in the analysis were change in best-corrected visual acuity (BCVA), change in central subfield thickness (CST), injection frequency, ocular adverse events (AE) and all-cause discontinuation, all of which were evaluated at 12months. Subgroup analyses including patients' naïve to anti-VEGF were conducted where feasible. Twenty-six studies identified in the SLR were included in the NMA. Most importantly for decision making in clinical practise, faricimab T&E was associated with a statistically greater (95% credible intervals exclude zero) and clinically meaningful decrease in retinal thickness compared to all other flexible dosing regimens (greater retinal drying by 55-125 microns). Anatomical outcomes determine treatment efficacy and retreatment of patients. The NMA also showed a statistically greater increase in mean change in BCVA for faricimab T&E vs. flexible regimens using ranibizumab and bevacizumab (increase of 4.4-4.8 letters) as well as a numerical improvement vs. aflibercept PRN (two letters, 95% credible intervals including zero). Accordingly, the injection frequency was numerically lower versus other treatments using flexible dosing regimens (decrease by 0.92-1.43 injections). The analyses also indicated that the safety profile of faricimab T&E was comparable to those of ranibizumab and aflibercept, which have well-established safety profiles, with similar results for the number of all-cause discontinuations. Faricimab provides a new treatment option in DME with dual-pathway inhibition of VEGF and angiopoeitin-2 (Ang-2). To the authors' knowledge, this is the first indirect comparison of faricimab T&E in DME. The analyses indicate that faricimab T&E is associated with superior retinal drying along with numerically fewer injections compared to all other treatments given in flexible dosing regimens. It also showed superior visual acuity outcomes compared to ranibizumab and bevacizumab.

27‑Gauge vitrectomy vs. 25‑gauge vitrectomy in the management of proliferative diabetic retinopathy with preoperative intravitreal injection of conbercept.

Small-gauge vitrectomy has become popular due to its notable advantages, including less trauma, shortened convalescence and improved manoeuvrability. The aim of the present study was to compare the surgical outcomes of 27-gauge (27-G) vitrectomy with those of 25-gauge (25-G) vitrectomy in the management of proliferative diabetic retinopathy (PDR) with preoperative intravitreal injection of conbercept. The data of 48 consecutive patients with PDR (48 eyes) were retrospectively collected. The patients underwent conbercept intravitreal injection and pars plana vitrectomy with a 27-G group (23 eyes) or 25-G group (25 eyes) vitrectomy system. The operating time, suturing rate, endodiathermy rate, postoperative best-corrected visual acuity (BCVA), intraocular pressure (IOP) and complications were recorded. The mean postoperative BCVA at final follow-up was significantly improved compared with that at the baseline in both groups (P<0.001 for both). The differences in the mean BCVA changes between the two groups were not significant (P>0.99), and no differences were observed in the final central foveal thickness (P=0.51) between the two groups. The final IOP remained stable compared with that at the baseline in the 27-G group (P=0.36) and the 25-G group (P=0.05). The suturing rate was significantly decreased in the 27-G group compared with the 25-G group (P=0.04). There were no significant differences between the two groups in terms of the operating time (P=0.18), rate of endodiathermy use (P>0.99), iatrogenic retinal breaks (P=0.42) or postoperative recurrent vitreous haemorrhage (P>0.99). In addition, no case of ocular hypotony was observed in either group. In conclusion, 27-G vitrectomy was as efficient and safe as 25-G vitrectomy in the management of PDR in terms of operating time and complications. With reference to the literature, preoperative conbercept injection appears to assist in decreasing the incidence of intraoperative and postoperative complications.

Aflibercept for Diabetic Macular Edema in Real-Life Practice in GREece: Three-Year Outcomes of the ADMIRE Study

ABSTRACT Purpose To evaluate the efficacy and safety of intravitreal aflibercept injections for diabetic macular edema (DME) treatment in a tertiary referral center in Greece. Methods ADMIRE was a prospective, observational cohort study of patients with DME. Efficacy was assessed by change in best-corrected visual acuity (BCVA) and central subfield thickness (CST) from baseline to month 36 after treatment with intravitreal aflibercept in treatment-naive patients and previously treated patients. Safety was evaluated by recording any patients-reported events. Results Participants in the study were 94 patients with DME, 70 treatment naive and 24 previously treated with ranibizumab. At month 36 of the follow-up period, the mean change in BCVA was +7.4 letters compared to baseline (p < .001). The mean change in BCVA in treatment-naive patients was +8.9 letters and differed significantly compared to previously treated patients (+5.9 letters, p = .041). In addition, patients who received a loading dose of 5 monthly injections at the initiation of treatment provided better VA outcomes (+11.4 vs. +6.1 letters, p < .001). Accordingly, the mean CST at month 36 (369.6 ± 72.8 μm) was significantly decreased compared to baseline (479.2 ± 68.3 μm, p < .001). Overall, the mean number of injections at month 36 was 13.4. Safety analysis showed that the reported ocular adverse events during the 36-month study period were mild and not sight-threatening. Conclusion Intravitreal aflibercept was found to be safe and effective for the treatment of DME in real-life in a Greek population. Treatment-naive patients and those who received a loading dose of five consecutive monthly injections at initiation of treatment exhibited better outcomes, suggesting that early and effective treatment may prevent vision loss.

SCLERAL FIXATION OF CARLEVALE INTRAOCULAR LENS: A Systematic Review and Meta-Analysis.

The mean change in best-corrected visual acuity (BCVA), intraocular pressure, and endothelial cell counts after intraocular lens (IOL) implantation and the incidence rate of postoperative complications were estimated by systematic review and meta-analysis to assess the surgical and refractive outcomes of the sutureless scleral fixation Carlevale IOL. A literature search was conducted using PubMed, Embase, and Scopus. The weighted mean difference (WMD) was used to present the mean change in BCVA, intraocular pressure, and endothelial cell count after IOL implantation, whereas a proportional meta-analysis was used to estimate the pooled incidence rate of postoperative complications. In the meta-analysis of 13 studies involving 550 eyes, the pooled WMD of the mean change in BCVA showed a significant improvement in BCVA in patients who underwent Carlevale IOL implantation (WMD = 0.38, 95% confidence interval: 0.30-0.46, P < 0.001; heterogeneity [I 2 ] = 52.02%). The subgroup analyses indicated that the mean change in BCVA was not significantly higher according to the last follow-up visit, with no statistically significant subgroup effect ( P = 0.21) (WMD up to 6 months: 0.34, 95% confidence interval: 0.23-0.45, I 2 = 58.32%, WMD up to 24 months: 0.42, 95% confidence interval: 0.34-0.51, I 2 = 38.08%). In the meta-analysis of 16 studies involving 608 eyes, the pooled incidence rate of postoperative complications was equal to 0.22 (95% confidence interval: 0.13-0.32, I 2 = 84.87, P ≤ 0.001). Carlevale IOL implantation represents a reliable method of restoring vision in eyes with missing capsular or zonular support.

Comparison of anatomical and functional outcomes of treating myopic choroidal neovascularization with bevacizumab or ranibizumab.

To compare results of treatment with bevacizumab and ranibizumab injections in myopic choroidal neovascularization (mCNV). Retrospective, observational case series. patients with mCNV treated with bevacizumab or ranibizumab injections. Best corrected visual acuity (BCVA) and central retinal thickness (CRT) on optical coherence tomography (OCT) scans were collected at baseline, after 3, 6, 12, 24months and the last visit. mean change in BCVA and CRT. We included 85 eyes treated with bevacizumab and 125 eyes treated with ranibizumab. There was no difference between the groups regarding BCVA and CRT change. CNV recurrence occurred at the mean time of 66.1 ± 3.7 and 57.3 ± 6.4months in the bevacizumab- and ranibizumab-treated eyes, respectively (p = 0.006). During the first year 6.9% eyes in the bevacizumab group vs. 27.5% in the ranibizumab group had CNV recurrence (p = 0.001). Risk factors for recurrence of CNV were baseline CNV area (aHR 1.20, 95%CI 1.0-1.32, p = 0.04), subfoveal CNV (aHR 2.13, 95% CI 1.16-3.93, p = 0.01) and ranibizumab treatment (aHR 2.31, 95% CI 1.16-3.93, p = 0.008). Eyes treated with bevacizumab and ranibizumab can achieve similar anatomical and functional improvement. CNV recurrence may occur earlier and more frequently during the first year in eyes treated with ranibizumab.
