Success of Intravitreal Ranibizumab for Myopic Choroidal Neovascularization After 2 Years of Treatment

Purpose: To analyze the anatomical and functional outcomes in patients with choroidal neovascularization (CNV) secondary to pathological myopia (PM). Methods: Retrospective review of the medical records of 40 patients with CNV secondary to PM treated exclusively with intravitreal ranibizumab 0.5 mg and at least 24 months of follow-up. The initial dose comprised 1 or 3 monthly injections followed by a pro re nata regimen. Best-corrected visual acuity (BCVA), central retinal thickness (CRT) measured with spectral domain optical coherence tomography (OCT), and ocular and systemic adverse event were recorded. Results: Mean patient age was 62.5 ± 12.5 years. The mean spherical equivalent refractive error was −12.3 ± 6.9 diopters, and a single intravitreal injection was initially performed in 72.5% of cases. Mean baseline BCVA was 0.33 ± 0.20 logMAR (Snellen equivalent, 20/60), and mean CRT by OCT was 340.65 ± 80 µm. Both BCVA and OCT revealed significant improvement compared to baseline at all established cutoff points ( P < .001). Final BCVA was 0.50 ± 0.3 logMAR (Snellen, 20/40), and final CRT was 255.69 ± 47.7 µm ( P < .001). The mean number of ranibizumab injections was 2.75 ± 1.97. No cases of endophthalmitis or retinal detachments were reported, and no serious adverse systemic events were identified. Conclusion: Excellent anatomical and functional outcomes were obtained after treatment with intravitreal ranibizumab for CNV secondary to PM.

Abstract Background: Calcium dobesilate (CaD) had been used in the treatment of diabetic retinopathy (DR) due to its potential in protecting against retinal vascular damage. However, it did not reduce the risk of development of diabetic macular edema (DME). The aim of this study was to investigate the effect of CaD plus intravitreal ranibizumab in the treatment of DME.Methods: This retrospective, observational, consecutive case control study enrolled patients newly diagnosed with DME who received intravitreal ranibizumab (IVR) administration with 3-monthly loading dose injection followed by pro re nata (3+PRN) regimen with or without CaD orally daily for at least 12-month follow-up. Medical records and optical coherence tomography (OCT) results were reviewed and compared at baseline and at 3, 6, and 12 months after injection.Results: A total of 102 eyes from 102 patients were enrolled in this study. Fifty-four patients received IVR combined with CaD orally (IVR+CaD group), while forty-eight patients received IVR solely (IVR group). No statistically significant differences were found in the general condition of patients between the two groups at baseline (P > 0.05). At every follow-up, 3, 6 and 12 months after injection, the best corrected visual acuity (BCVA) improved and the central macular thickness (CMT) decreased in both groups when compared with those at baseline (P < 0.05), while there were no significant differences in BCVA improvement and CMT reduction between the two groups (P > 0.05). The mean number of ranibizumab injections in R+C group was significantly lower than that in R group (5.4 ± 1.1 injections versus 6.7 ± 1.6 injections, P<0.05) within 1-year treatment. No adverse events were found in neither groups.Conclusions: Adding oral CaD to intravitreal ranibizumab was demonstrated to have similar effectiveness and safety for improving visual function and restoring the anatomy of the retina in macular with fewer injections in DME patients.

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.

The aim of this study was to compare the effectiveness of intravitreal ranibizumab (IVR) injections for the treatment of diabetic macular edema (DME) in eyes with and without previous vitrectomy. The medical records of 28 eyes (11 vitrectomized and 17 nonvitrectomized) of 28 patients (mean age, 59.0 ± 9.6 years; male to female ratio 1 : 1) who were diagnosed with DME and had received IVR treatment were reviewed retrospectively. The indications of vitrectomy in 11 vitrectomized eyes were intravitreal hemorrhage (n = 8) and epiretinal membrane (n = 3). The best-corrected visual acuity (BCVA), central macular thickness (CMT), and total macular volume (TMV) were measured at baseline and at months 6, 12, 18, and 24 of the follow-up. The number of IVR injections, the duration between diagnosis of DME and IVR injection, and the hemoglobin A1c (HbA1c) level at baseline were also recorded. Baseline demographics, HbA1c, BCVA, CMT, and TMV values were similar between two groups (p>0.05). The duration between diagnosis of DME and IVR injections was similar in both groups (16 ± 5 months vs. 13 ± 4 months, respectively; p=0.11). IVR injection was performed 6.3 times in vitrectomized eyes and 6.1 times in nonvitrectomized eyes during the 24-month period (p>0.05). The mean BCVA improved significantly during the 24-month period in both groups. The improvements in BCVA, in CMT, and in TMV were more significant at month 6 (p=0.036) group, at month 12 (p=0.013), at month 12 (p=0.021), and month 24 (p=0.021) in nonvitrectomized eyes, respectively, while there was no difference in improvements of BCVA, CMT, and TMV in vitrectomized group at each visit. Treatment effected by time in terms of BCVA, CMT, and TMV values in all groups (p=0.0004, p<0.0001, p<0.0001, respectively), not by time-group interaction and group (all p values >0.05). In conclusion, IVR treatment for DME is equally effective in both groups. However, the response to treatment is seen earlier in nonvitrectomized eyes compared to vitrectomized eyes.

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 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 Snellen 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 mm 2 at baseline to 0.31 ± 0.19 mm 2 at 12 months (P < 0.05). All the 34 eyes had reduced or stable size of CNV, thirty-two eyes (94.12%) showed absence of CNV leakage at the end of the study period. No severe complications were observed. Conclusion: Intravitreal conbercept 0.5mg was safe and effective for treatment of myopic CNV over 12 months in real-life setting.

Background. To compare visual outcomes and spectral-domain optical coherence tomography results following intravitreal ranibizumab treatment for early and mid-idiopathic choroidal neovascularization (ICNV).Methods. This retrospective, case-controlled study examined 44 patients with ICNV in one eye initially treated with intravitreal ranibizumab (0.5 mg). Further intravitreal treatments were administered as necessary. Patients were divided into two groups according to disease duration, that is, ≤3 months or 3–6 months (early and mid-groups), and the data were compared.Results. All patients completed at least 12 months of follow-up. Significant differences were observed between the groups in best-corrected visual acuity and in central macular thickness (CMT) reduction at all five follow-up visits. At the last follow-up (12 months), 19 early group eyes (79.1%) and 10 mid group eyes (50.0%) had statistically significant visual gains of >15 early treatment diabetic retinopathy study (ETDRS) letters(χ2=4.130, P=0.042). The mean number of injections was significantly higher (P=0.0001)in the mid group(2.53±1.76)than in the early group(1.22±1.01).Conclusions. Early intravitreal ranibizumab for ICNV can result in better visual prognoses, more obvious decreases in CMT, and fewer injections.

Objective: Evaluation of central corneal densitometry changes following Ferrara corneal ring segment implantation in patients with keratoconus, especially the correlation between corneal densitometry and keratometry. Methods: Retrospective, non-comparative, interventional study based on the review of medical records of patients diagnosed with keratoconus who underwent Ferrara corneal ring segment implantation. Pre and post-operative corneal densitometry measurements obtained with Pentacam HR (Oculus, Wetzlar, Germany) were analyzed. The follow-up time was 3 months, and data comparison was made, using specific statistical analysis, with the data of 3 months postoperatively. Results: The study sample consisted of 43 eyes of 36 patients. The mean corrected visual acuity improved from 0.82 LogMAR preoperatively (SD ± 0.33) to 0.19 LogMAR (SD ± 0.13) postoperatively. The mean spherical equivalent varied from −4.63 (SD ± 3.94) preoperatively to −2.16 (SD ± 2.63) postoperatively. Asphericity varied from −0.69 (SD ± 0.32) preoperatively to −0.27 (SD ± 0.31) postoperatively. The mean maximum K was 54.01D (SD ± 3.38) preoperatively and 51.50D (SD ± 2.90) postoperatively. The mean anterior densitometric value was 18.26 (SD ± 2.03) preoperatively and 17.66 (SD ± 1.84) postoperatively. Conclusion: Corneal densitometry is an interesting technology that should be studied in keratoconus patients. Our results suggest that the corneal densitometry in the cornea’s anterior layer reduces after ICRS implantation and correlates with corneal keratometry. Further studies should be performed to increase the knowledge in this field.

Background: Amblyopia is more common in children with high astigmatism, but factors contributing to development of amblyopia and visual outcomes are not fully understood. Objective: To evaluate the effect of amblyopia on the clinical outcomes in children with ⩾1.75 diopter (D) astigmatism. Methods: We reviewed the medical records of children with ⩾1.75 D astigmatism with and without amblyopia (amblyopes group and non-amblyopes group). The mean age, gender, amount and type of ocular deviation, presence of convergence insufficiency (CI), stereopsis, time of initial spectacle use and follow-up time, differences in best-corrected visual acuity (VoD) and spherical equivalent (SE) between eyes were assessed and compared between the groups. Best-corrected visual acuity (BCVA), mean SE, astigmatism measurements were assessed and compared between amblyopic, fellow, and non-amblyopic eyes. Results: The records included 68 eyes of 34 children with amblyopia and 56 eyes of 28 children without amblyopia. The mean age, gender, amount and type of ocular deviation, presence of CI, stereopsis, time of initial spectacle use, follow-up time, and the difference in SE did not differ between groups. In amblyopes, exodeviation was more common and statistically greater in near (33 cm) than at distance (6 m) (p = 0.005). The mean BCVA and astigmatism values were statistically different between amblyopic, fellow, and non-amblyopic eyes. Conclusion: A greater near than distance exodeviation and higher mean astigmatism value were found in amblyopic children with astigmatism.

Purpose: To compare the response to ranibizumab between patients with typical neovascular age-related macular degeneration (tAMD) and those with polypoidal choroidal vasculopathy (PCV), and to determine the predictors for the outcomes. Methods: Fifty-nine eyes from 59 consecutive patients (tAMD: 27 eyes, PCV: 32 eyes) were treated with three monthly ranibizumab injections followed by as-needed retreatment. Best-corrected visual acuity (BCVA) and morphological parameters were evaluated over 24 months of follow-up. Results: The mean BCVA in tAMD and PCV patients was significantly improved at 3 months (-0.22 and -0.09 logMAR units, respectively). The improvement in BCVA was sustained up to 24 months in tAMD (p = 0.01) but not in PCV patients. The significant predictor for good response to ranibizumab in tAMD patients was the improvement of BCVA at 3 months, whereas that in PCV patients was the anatomical resolution at 3 months. Conclusions: Ranibizumab is an effective therapy for tAMD and PCV over 24 months. The predictors for good outcome might be different between tAMD and PCV.

AIM: To evaluate the one-year outcome of intravitreal conbercept injections for the treatment of choroidal neovascularization secondary to pathological myopia (pm-CNV) by optical coherence tomography angiography (OCTA). METHODS: The medical records of 26 consecutive eyes of 23 patients who received intravitreal injections of conbercept for pm-CNV with a follow-up of one year were retrospectively reviewed. All the patients were diagnosed by fundus fluorescein angiography (FFA) and OCTA at the first visit. All approaches were performed as “1+PRN” treatment. Outcomes included best-corrected visual acuity (BCVA), central foveal thickness (CFT) and the mean CNV area by OCTA. RESULTS: Mean Logarithm BCVA improved from (0.66±0.51) at baseline to (0.39±0.38) at one year (t=3.528, P=0.004). The CFT before treatment and after one year after were 275.08±48.74) μm and (205.15±43.74) μm respectively (t=4.630, P=0.001). The mean pm-CNV areas before treatment and after one year treatment were (0.48±0.24) mm2 and (0.15±0.11) mm2 respectively, with a significant difference among them (t=5.329, P=0.000). Twenty-one eyes had no needs after the first treatment. Four eyes received 2 injections and only one eye received 3 injections. No severe adverse events were noted relevant to the therapy. CONCLUSION: Intravitreal conbercept can improve the vision and relieve CFT and CNV area for the treatment of pm-CNV with “1+PRN” by OCTA for one year, however, long-term follow-up still need to be performed.
