Ziel: Beurteilung der mittel- und langfristigen Wirksamkeit von Anti-VEGF-Wirkstoffen in der Behandlung der choroidalen Neovaskularisation infolge einer pathologischen Myopie (myopic choroidal neovascularization; mCNV).Methoden: Retrospektive Analyse von mCNV-Patienten, die 2 Jahre oder länger mit einer intravitrealen Anti-VEGF-Therapie behandelt worden waren. Wir verglichen die Sehschärfe mit bester Korrektur (best-corrected visual acuity; BCVA) sowie die zentrale Netzhaut-Dicke (central retinal thickness; CRT) vor und nach der Behandlung. Die Anzahl der Injektionen pro Jahr wurde ebenfalls erfasst.Ergebnisse: Auswertungen der Ergebnisse erfolgten nach 2 Jahren für 67 Augen, nach 3 Jahren für 52 Augen, nach 4 Jahren für 28 Augen und nach 5 Jahren für 13 Augen. Die mittlere Veränderung der BCVA gegenüber dem Ausgangswert war nach 2 Jahren signifikant (+8,6 Buchstaben; p < 0,001); diese Verbesserung blieb über einen Zeitraum von 5 Jahren signifikant stabil bestehen. Die mittlere CRT nahm im Verlauf signifikant ab; der Tiefstwert war nach 2 Jahren erreicht (-104,0 μm; p < 0,001). Die mittlere Anzahl der Injektionen betrug im 1. Jahr 5,2 und ging in den nachfolgenden Jahren zurück (p < 0,001).Schlussfolgerung: In der hier beschriebenen Untergruppe von mCNV-Patienten war die intravitreale Anti-VEGF-Therapie über einen Zeitraum von 5 Jahren wirksam, wobei sich der BCVA-Wert fortwährend erhöhte.Übersetzung aus Ophthalmologica 2014;232:57-63 (DOI: 10.1159/000360307)

Purpose: To compare visual functional improvement and retinal structural changes of aflibercept versus ranibizumab for the management of treatment-naïve choroidal neovascularization related to pathological myopia. Patients and methods: A prospective randomized study included patients suffering from myopic choroidal neovascularization. Patients received three intravitreal injections of aflibercept (2 mg) or ranibizumab (0.5 mg) in 1:1 ratio every 4 weeks. Ophthalmic evaluation and optical coherence tomography were performed at baseline, 1, 2, and 3 months after last injection. Primary outcome measure was the visual acuity change from baseline to month 3 after injection. Secondary outcome measures included change in retinal thickness and the relation of morphological and functional changes to baseline assessment parameters. Results: A total of 48 myopic patients (48 eyes) suffering from myopic choroidal neovascularization were randomly assigned to receive either aflibercept (Group A) or ranibizumab (Group B). In Group A, best-corrected visual acuity significantly improved from 0.53 ± 0.10 logMAR to 0.38 ± 0.11 logMAR, at 3 months, and from 0.55 ± 0.11 logMAR to 0.39 ± 0.12 logMAR in Group B. Whereas, retinal thickness reduced from 317.7 ± 53.6 µm to 164.5 ± 81.9 µm in Group A, and from 321.1 ± 98.8 µm at baseline to 178.9 ± 64.5 µm in Group B at month 3. Changes in best-corrected visual acuity and central macular thickness were statistically insignificant between the two groups at final visit. Conclusion: Both aflibercept and ranibizumab provided a significant improvement in visual acuity and retinal thickness in patients with myopic choroidal neovascularization. Comparable functional and architectural results were achieved by both treatment modalities.

The purpose of the study was to evaluate changes in best corrected visual acuity, central retinal thickness, area and flow in the neovascular membrane and to compare therapeutic outcomes from baseline in patients who received three doses of Beovu (brolucizumab) at three-month follow-up. Material and methods: A prospective observational study conducted at the Prof. K. Gibiński University Clinical Center of the Medical University of Silesia in Katowice. Eight patients with exudative form of age-related macular degeneration (AMD) were observed. Results: The mean best corrected visual acuity (BCVA) outcome increased with each subsequent visit. The mean central retinal thickness (CRT) result also improved (decreased) with each subsequent visit, except for the last measurement. A statistically significant change in neovascular membrane area was observed after the first injection. In further treatment, the membrane area underwent changes that were not statistically significant. A statistically significant change in neovascular membrane flow was demonstrated after the first and second injections. Discussion: Our study confirmed the efficacy of brolucizumab in the treatment of patients with exudative AMD in terms of improvements in best corrected visual acuity (BCVA), central retinal thickness (CRT), neovascular membrane area, and neovascular membrane flow area.

<strong>Introduction:</strong> Choroidal neovascularization secondary to pathological myopia is one of the leading causes of irreversible central vision loss in younger patients. The purposes of our study is to evaluate the long-term results of antiangiogenic treatment, with ranibizumab and/or bevacizumab, in myopic choroidal neovascularization and define the predictive factors for visual and anatomic outcomes.<br /><strong>Material and Methods:</strong> In this study were included 84 eyes from 81 patients with myopic choroidal neovascularization. Eighty-four (100%) eyes accomplish 12 months of follow-up, 67 (79.8%) 24 months, 54 (64.3%) 36 months, 29 (34.5%) 48 months, and 15 (16.7%) 60 months. We retrieved data related to best corrected visual acuity measured with ETDRS chart, foveal center thickness on optical coherence tomography and fluorescein angiographic findings, before and after treatment.<br />Results: The best corrected visual acuity and foveal center thickness improvements were statistically significant for all follow-up times (p &lt; 0.05). Mean baseline best corrected visual acuity was 43.7 ± 20.1 letters and mean baseline foveal center thickness was 304.8 ± 127.9μm. Mean best corrected visual acuity was 55.6 ± 18.5, 52.1 ± 22.3, 52.1 ± 22.6, 50.3 ± 23.8 and 47.8 ± 24.5 for 12, 24, 36, 48 and 60 months of treatment, respectively. Mean foveal center thickness was 209.7 ± 86.2, 190.6 ± 76.1, 174.7 ± 60.6, 189.8 ± 96.7 and 159.4 ± 73.3 for the same follow-up times. Baseline best corrected visual acuity was the only predictive factor for better visual outcome (p &lt; 0.001).<br /><strong>Discussion/Conclusion:</strong> Intravitreal anti-VEGF injections in patients with myopic choroidal neovascularization yielded a significant and sustained functional and anatomic improvement. Randomized long-term clinical trials are needed to determine the sustained efficacy of these drugs.

Abstract Purpose Central serous chorioretinopathy is a complex ocular entity that, in its chronic form, can lead to serious visual impairment and morphological damage to the retina. The aim of the current retrospective study was to evaluate the damage present after long-standing but resolved central serous chorioretinopathy. Correlations between measurable factors—for example, duration of the disease, baseline retinal morphological parameters, or patient age and/or their degree of impairment—were also assessed. Materials and methods Thirty-two eyes with chronic central serous chorioretinopathy in which complete resolution of subretinal fluid was achieved after subthreshold micropulse laser treatment were analyzed according to final best-corrected visual acuity and retinal morphological parameters as measured by spectral optical coherence tomography with angiography option (OCTA). Results were compared with the outcomes of a control group. Statistical analysis included regarding correlation between final visual acuity and final central retinal thickness and retinal and functional parameters prior to treatment. Results Final best-corrected visual acuity after chronic central serous chorioretinopathy was 0.23 logMAR (0.6 Snellen) and central retinal thickness was 39.32 µm smaller than in controls. No correlation was found between final visual acuity and retinal thickness and duration of the disease, patient age, and baseline morphological retinal parameters. OCTA scans revealed impaired choroidal perfusion even following resolution of the disease. Conclusion Chronic central serous chorioretinopathy is a potentially damaging clinical entity that results in serious visual impairment, retinal thinning, and choroidal flow defects. No significant correlation between duration of central serous chorioretinopathy and amount of visual deficit has been found, therefore it is possible that the biggest damage occurs within the first months of active chorioretinopathy.

Objective: To evaluate, in the setting of persistent diabetic macular edema, the impact that continuous fluocinolone acetonide delivery has on treatment burden, visual acuity, central retinal thickness, and intraocular pressure. Materials and methods: A single-center, retrospective, cohort study of patients with persistent diabetic macular edema, previously treated with anti–vascular endothelial growth factor injections, dexamethasone implants, or focal laser, who were subsequently treated with fluocinolone acetonide was conducted. All retinal visits were analyzed prior to fluocinolone acetonide, until the most recent follow-up visit. Primary outcomes were pre– and post–fluocinolone acetonide changes in the best-corrected visual acuity and number of treatments required for diabetic macular edema. Secondary outcomes included changes in the central retinal thickness and intraocular pressure. Results: A total of 19 eyes with persistent diabetic macular edema were included and followed for a mean (SD) of 399.3 (222.9) days. Post–fluocinolone acetonide, the mean best-corrected visual acuity improved by 0.4 ETDRS letters for all eyes ( p = 0.895) and the central retinal thickness decreased by 34.2 µm ( p = 0.077). After fluocinolone acetonide, the number of treatments decreased from an average of one treatment every 2.7 months to one every 6 months ( p = 0.009). Furthermore, post–fluocinolone acetonide, 10/19 eyes (52.6%) did not require additional treatment due to a dry macula, and those who did experienced a non-statistically significant reduction of treatments, from one every 2.6 months pre–fluocinolone acetonide, to one every 2.8 months post–fluocinolone acetonide ( p = 0.622). Conclusions: In the setting of persistent diabetic macular edema, fluocinolone acetonide significantly reduces the therapeutic burden, while maintaining best-corrected visual acuity and improving the central retinal thickness. In patient-centered discussions, judiciously employing fluocinolone acetonide should be performed to mitigate this therapeutic burden for patients.

Abstract Background Subthreshold microsecond pulsing laser is an increasingly common treatment approach for central serous chorioretinopathy. However, there is no literature available on the safety of microsecond laser using different fluence settings in this disease. While many publications can be obtained from conventional microsecond pulsing lasers, few parameter sets are published with the navigated microsecond pulsing laser. Therefore, this study aims to investigate the safety of different parameter sets in subthreshold microsecond pulsing laser treatments. Methods In this retrospective chart review, consecutive patients with central serous chorioretinopathy (> 3 months duration of symptoms) treated with navigated subthreshold microsecond pulsing laser and a follow up of at least five months after microsecond laser application were included. For each patient, the treatment parameters, plan layout, and adverse events related to laser were evaluated. Secondary outcomes included best-corrected visual acuity and anatomical improvements (central retinal thickness). Results One hundred and one eyes were included in the observation and followed for a mean of 10 months (range 5–36). Although a larger range of parameter sets and fluence settings have been used, no patient demonstrated adverse events from navigated microsecond pulsing laser. While 88% of the cases demonstrated stability, 13 cases lost five or more letters due to the persistence of the subretinal fluid. In mean, a best-corrected visual acuity improvement of 0.07logMar (± 0.2) was seen (p = 0.02). In 51% of the patients, a statistically significant improvement of the central retinal thickness was noted at the last follow-up with a mean thickness reduction of 70 µm (± 143) (p < 0.01). Conclusion In conclusion, none of the used parameter sets lead to tissue damage (when using a cautious titration) and, in summary, lead to an improvement in subretinal fluid and improvement in visual acuity. However, further prospective studies are needed to correctly identify the dependency of the treatment strategy on the outcome criteria.

Purpose: It was the aim of this study to determine the efficacy of intravitreal ranibizumab as treatment of choroidal neovascularizations associated with pathologic myopia. Materials and Methods: In an uncontrolled, prospective time series cohort study, 65 eyes of 64 consecutive patients with choroidal neovascularization associated with pathologic myopia were treated with intravitreal ranibizumab and observed over 12 months. The change in best-corrected visual acuity (BCVA) at 6 and 12 months served as primary end point. Safety, central retinal thickness, neovascularization activity on fluorescein angiography and the number of ranibizumab injections were secondary end points. Results: BCVA improved significantly throughout the follow-up (p = 0.001). The mean BCVA was 0.2 at baseline (SD 0.13) and 0.4 at 12 months (SD 0.21). Improvement was strongest within the first 3 months (p = 0.0001). The mean central retinal thickness showed a reduction from 313 μm (SD 82) to 243.5 μm (SD 31; p = 0.0001). Conclusion: Intravitreal ranibizumab offers a safe and effective treatment for choroidal neovascularizations in pathologic myopia.

Abstract Background To evaluate the 12-month efficacy and safety of intravitreal conbercept for myopic choroidal neovascularization (CNV). Methods A retrospective, observational study. Thirty-four eyes of 34 pathologic myopic patients with CNV were treated with intravitreal conbercept (IVC) 0.5 mg with a follow up of 12 months. After the first injection, administration of conbercept followed a pro re nata (PRN) regimen. Outcomes included best corrected visual acuity (BCVA), central retinal thickness (CRT), CNV size, the total number of treatments, and adverse events. Results The mean patient age was 55.88 ± 16.17 years, and the mean eye spherical equivalent was − 8.72 ± 3.75 D. The mean number of IVC over 12 months was 2.12 ± 0.69. Overall, best-corrected visual acuity(BCVA)improved from 0.86 ± 0.33 logMAR at baseline to 0.44 ± 0.32 logMAR at month 12 (p < 0.001), mean improvement of vision was 4.12 ± 2.69 lines. Mean central retinal thickness reduced from 285.9 ± 104.6 µm at baseline to 192.1 ± 97.5 µm at month 12 (p < 0.001). Mean CNV size decreased from 0.52 ± 0.38 mm2 at baseline to 0.31 ± 0.19 mm2 at 12 months (p < 0.05). All the 34 eyes had reduced or stable size of CNV. Thirty-two eyes (94.12 %) showed the absence of CNV leakage at the end of the study period. No severe systemic or ocular adverse events were observed. Conclusions Intravitreal conbercept 0.5 mg was safe and effective for treatment of myopic CNV over 12 months in a real-world setting.

Despite the vitrectomy performed for diabetic macular edema (DME), some patients still have symptoms of the disease due to overproduction of VEGF by the ischemic retina, which requires regular administration of an antiangiogenic drug. Studies of the pharmacokinetics of antiangiogenic drugs after vitrectomy in humans have not been carried out. Data from the DRCR.net (Post-Hawk Protocol I) study and real-life clinical practice studies show similar results for anti-VEGF DMO therapy in vitreous eyes and after vitrectomy (2, 7). Purpose. To assess the effectiveness of antiangiogenic therapy with aflibercept for DMO in avitreal eyes in real clinical practice. Methods. The initial and after vitrectomy best corrected visual acuity (BCVA) and central retinal thickness (CRT) were determined according to OCT data, then these parameters were monitored by 1, 3, 6 and 12 months after the start of antiangiogenic therapy with aflibercept. 14 patients (14 eyes) with persistent DME underwent vitrectomy with removal of the internal limiting membrane, in 5 of them the epiretinal fibrosis was removed and 3 of them with a traction retinal detachment that was also removed with air tamponade. Results. Aflibercept intravitreal injections were started with 5 loading doses by 1-11 months after vitrectomy. On average, after 12 months, patients received 7.2 injections, while there was no need for laser surgery of the macular zone. By the end of the study, the CRT decreased by 255 ±86 µm, the BCVA was 0.35 ± 0.2 in comparison with the initial 0.07±0.03 (on a decimal scale). Conclusions. The effectiveness of the anti-VEGF therapy with aflibercept for DME in avitreal eyes was confirmed by an increase in functional (BCVA) and normalization of morphological (CRT on OCT) parameters after the first injections during the period of loading doses. Previous vitrectomies in patients with DMO do not affect the long-term favorable clinical outcomes of anti-VEGF therapy with aflibercept. Key words: vitrectomy, diabetic macular edema, aflibercept, anti-VEGF, OCT, best corrected visual acuity, central retinal thickness.
