Staphyloma-related chorioretinal folds.

PURPOSE: To report a case of bilateral idiopathic chorioretinal folds that seemed to be related to an atypical staphyloma. OBSERVATIONS: A 49-year old man without medical history consulted for slight vision loss and metamorphopsia in the left eye. The ophthalmologic examination revealed moderate myopia and bilateral chorioretinal folds in the posterior pole, confirmed by multimodal imaging. Orbital and systemic examinations ruled out all the known etiologies of chorioretinal folds. 3-D optical coherence tomography and B-scan suggested that the folds were related to an atypical staphyloma that developed in the temporal part of the fundus, while sparing the peripapillary area. The peripapillary area, spared by the staphyloma process, appeared as a "dome-shaped disc" compared to the staphylomatous area. CONCLUSION AND IMPORTANCE: This case suggests that myopic patients with unusual staphyloma located outside the peripapillary area could develop chorioretinal folds.

Impact of ranibizumab on visual impairment in patients with bilateral diabetic macular edema.

AIMS: Diabetic macular edema (DME) frequently presents bilaterally. In case of bilateral retinal disease, the visual impairment (VI) and the visual acuity (VA) are strongly correlated to the better eye. The aim of this study was to assess the impact of ranibizumab intravitreal injections (IVR) on VI in patients with simultaneous VA loss due to DME. METHODS: This was a retrospective two-center study including consecutive DME patients with visual loss treated with ranibizumab since November 2011 and with a minimum follow-up of 6 months. Patients with bilateral visual decrease from DME undergoing IVR within 6 months of each other were included. RESULTS: Twenty-nine DME patients who received bilateral IVR within a 6-month interval in the second eye were included. At baseline, 82.8% (n = 24) of patients had a VA < 20/40 in their better eye versus 44.8% (n = 13) of patients at the end of follow-up, i.e. a reduction by 45.9% of VI. In the better eye, the mean VA was 57.3, 65.0 and 65.5 ETDRS letters, respectively, at baseline, month 3 and month 6 (mean VA gain +8.2 letters). In the worse eye, the mean VA was 44.2, 53.5 and 53.8 ETDRS letters, respectively, at baseline, M3 and M6 (mean VA gain +9.6 letters). CONCLUSIONS: In patients with bilateral DME, subsequent ranibizumab IVR reduced VI frequency.

Treatment Efficacy and Compliance in Patients with Diabetic Macular Edema Treated with Ranibizumab in a Real-Life Setting.

PURPOSE: To assess real-life efficacy of ranibizumab and treatment compliance of patients with vision loss secondary to diabetic macular edema (DME). METHODS: A retrospective study was conducted in DME patients treated with ranibizumab. Patients were monitored every 4 weeks for visual acuity (VA) and central retinal thickness (CRT) by SD-OCT. All patients received a loading dose of 3 monthly injections followed by retreatments on an as-needed basis. The primary endpoint was the change in VA at M12. Patient compliance to the follow-up and the correlation between the injection number and VA were also investigated. Compliance was compared to that of neovascular age-related macular degeneration (nAMD) patients. RESULTS: Seventy-two eyes of 55 consecutive DME patients were included. At baseline, the mean VA was 56.5 letters and CRT was 470 µm. At M12, the mean VA was 63.4 letters (p < 0.0001), 31.1% of patients had a VA > 70 letters, the mean VA change was +6.9 letters, and the mean CRT was 361.9 µm (p = 0.0001) after a mean number of 5.33 intravitreal injections. In patients who received ≥7 injections, the VA gain and final VA were significantly higher than in patients who received <7 injections. At M12, 25.45% of DME patients were lost to follow-up versus 16.8% of nAMD patients (n = 55). DISCUSSION/CONCLUSION: Our study confirms the real-life efficacy of ranibizumab in DME at M12 and the need for a large number of injections to achieve better visual outcomes. We also showed a trend to a lower compliance in diabetic versus nAMD patients.

Ranibizumab for choroidal neovascularization secondary to pseudoxanthoma elasticum: 4-year results from the PIXEL study in France.

PURPOSE: To evaluate the long-term effectiveness and safety of ranibizumab 0.5 mg in patients with choroidal neovascularization (CNV) secondary to pseudoxanthoma elasticum (PXE) in a real-world setting. METHODS: A descriptive, observational, multicenter study in a retrospective and prospective cohort was conducted in France that included patients who had received at least one injection of ranibizumab 0.5 mg during the period October 2011 to October 2014, for CNV secondary to PXE. Eligible patients were identified by review of medical records or during routine consultations. The main objectives were to describe patient characteristics, assess changes in best-corrected visual acuity [VA, Early Treatment Diabetic Retinopathy Study (ETDRS) letters] over time, the number and reasons for ranibizumab treatment and overall safety. RESULTS: Of the 72 enrolled patients (98 eyes) from 23 centers, 39 (54.2%) were male and mean [±standard deviation (SD)] age was 59.6 (±8.3) years. The mean VA was 64.6 letters at the first ranibizumab injection, which was maintained at the 1-year follow-up (64.7 letters). Thereafter, the mean VA was stable until the 4-year follow-up. At 4 years, the proportion of eyes with VA gain of ≥15 letters was 3/19 (15.8%) and stable VA (change between -15 and +15 letters) was 10/19 (52.6%). Mean (±SD) annual number of ranibizumab injections was 4.1 (±4.0), lower in the second versus first year. The most common reason for ranibizumab treatment was progression of neovascular activity (42.9%). No deaths or new safety findings were reported. CONCLUSIONS: In patients with CNV secondary to PXE, ranibizumab 0.5 mg resulted in stable VA over 4 years with a limited number of injections. Safety findings were consistent with the established safety profile of ranibizumab.

Outcomes after a 1-Year Treatment with Ranibizumab for Diabetic Macular Edema in a Clinical Setting.

PURPOSE: The aim of this study was to assess the efficacy and safety of ranibizumab in patients with diabetic macular edema (DME). METHODS: We conducted a retrospective analysis of consecutive patients with vision loss due to DME who were treated with ranibizumab. All patients received a loading dose of 3 monthly injections followed by re-treatments on an as-needed basis. The primary endpoint was the change in best-corrected visual acuity (BCVA) at 12 months. Secondary endpoints were the change in central retinal thickness (CRT) and the number of intravitreal injections (IVI) at 12 months. RESULTS: One hundred and six eyes of 78 patients were included. BCVA changed from 48.3 (20/100) letters at baseline to 59.0 letters (20/63) at 12 months (p < 0.0001; mean gain: +10.7 letters), and 38% of the patients had a final BCVA >70 letters. CRT decreased from 519 µm at baseline to 355 µm at 12 months (p < 0.0001). The threshold of the first quartile of the baseline VA was 40 letters. Patients with a baseline VA >40 letters had a higher final VA of 66 ± 14 letters (20/50) versus 43 ± 18 letters (20/125) for patients with a baseline VA ≤40 letters (p < 0.0001). A mean number of 5.4 (3-10) IVI were administered. CONCLUSION: This study conducted in a clinical setting confirms the results of previous randomized trials. The final BCVA was mainly influenced by the baseline BCVA, which supports the utility of early DME treatment before patients experience a severe vision loss.

Estimation of the need for bilateral intravitreal anti-VEGF injections in clinical practice.

BACKGROUND: To estimate the need for bilateral intravitreal anti-VEGF injections in patients treated for neovascular age-related macular degeneration (nAMD), diabetic macular edema (DME), retinal vein occlusion, choroidal neovascularization (CNV) in high myopia, and other causes of CNV. METHODS: All consecutive patients treated with intravitreal anti-VEGF injection over a 1-month period were included in a prospective multicenter survey. The reason for intravitreal anti-VEGF injection and the involvement of the fellow eye in the pathology requiring a treatment with intravitreal anti-VEGF were recorded. A time interval between bilateral injections longer than 1 month, within a 1-month period, and same-day bilateral injections were recorded. RESULTS: A total of 1335 patients were included, corresponding to 1024 (76.7 %) patients treated for nAMD, 167 (12.5 %) for DME, and 144 (10.8 %) for other reasons. Four hundred and fifty-nine (34.4 %) patients were treated bilaterally with a time interval between injections longer than 1 month, 170 (12.7 %) were treated bilaterally within a 1-month interval, and 87 (6.6 %) had same-day bilateral injections. Bilateral injections were more frequent in diabetic patients than in nAMD patients (respectively 48 % vs. 36 %, p = 0.0033). CONCLUSIONS: Patients with DME are more likely to be treated bilaterally with anti-VEGF injections. As the rate of second eye involvement requiring treatment increases progressively over time, a same-day bilateral injection strategy will become more common as it decreases the administrative burden on the healthcare system and treatment burden experienced by patients.

BRIDGE ARCH-SHAPED SEROUS RETINAL DETACHMENT IN AGE-RELATED MACULAR DEGENERATION.

PURPOSE: To describe bridge arch-shaped serous retinal detachment (SRD) in exudative age-related macular degeneration and evaluate its functional outcomes. METHODS: In this monocentric, retrospective, noncomparative case series, patients were included. Patients with exudative age-related macular degeneration and bridge arch-shaped SRD treated with ranibizumab were included. Anatomical patterns of SRD and functional outcomes were assessed. RESULTS: Twenty-two eyes with bridge arch-shaped SRD of 22 patients with age-related macular degeneration were included. Serous retinal detachments were characterized by a steep angle at the junction between the retinal pigment epithelium and the sensory retina (mean, 53.45 ± 12.5°), and characterized by the presence of adhesion areas between the sensory retina and a fibrous complex developed from the choroidal neovascularization. In 15 eyes, the choroidal neovascularization was classic choroidal neovascularization and a fibrotic evolution was observed. Serous retinal detachments were compartmentalized in 14 eyes, leading to a multipocket structure. Visual acuity decreased from 49.9 ± 19.2 letters (20/100) to 40.3 ± 18.6 letters (20/160), corresponding to a mean change of -9.6 ± 19.4 letters. CONCLUSION: This was the first study to describe the specific morphologic features of bridge arch-shaped SRD, a previously undescribed type of SRD complicating exudative age-related macular degeneration. Patients with bridge arch-shaped SRD responded to intravitreal injections of ranibizumab, but their visual prognosis was unfavorable, compared with the literature. The presence of bridge arch-shaped SRD seemed to be a marker for the fibrotic evolution of the choroidal neovascularization.

PERIPAPILLARY RETINAL PIGMENT EPITHELIUM CHANGES IN AGE-RELATED MACULAR DEGENERATION.

PURPOSE: To describe peripapillary retinal pigment epithelium changes observed in patients with age-related macular degeneration (AMD) and evaluate their prevalence. METHODS: This study is a prospective, monocentric, comparative case series including 104 consecutive patients with AMD, and 34 patients who are more than 60 years old and consulting for other conditions (control group). Color and fundus autofluorescence images centered on the optic disk were taken and graded by 2 independent readers from 0 to 4: 0, absent; 1, uneven background; 2, focal hyperautofluorescent dots and spots; 3, light reticular pattern; 4, dense reticular pattern. Statistical analysis was performed to correlate the presence of peripapillary retinal pigment epithelium changes with age, sex, and AMD subtype. RESULTS: Peripapillary retinal pigment epithelium changes were observed in 76/104 AMD eyes (73.0%) and were significantly more frequent than in eyes with other conditions (14/34, 41.1%, P = 0.002), whereas groups did not differ for age (P = 0.14). Grade ≥2 peripapillary retinal pigment epithelium changes were more frequently observed in patients with AMD than in controls (41.3 vs. 17.6%, P = 0.013). No differences were found between patients with AMD having peripapillary retinal pigment epithelium changes and other patients for age distribution (P = 0.14), sex ratio (P = 0.34), or AMD type (P = 0.57). CONCLUSION: Peripapillary retinal pigment epithelium changes were more frequent in patients with AMD than in controls, and when present, they were of higher grade. Peripapillary retinal pigment epithelium changes significance is not yet understood and needs further evaluation.

Long-term variable outcome of myopic choroidal neovascularization treated with ranibizumab.

PURPOSE: The purpose was to evaluate the long-term efficacy of ranibizumab for the treatment of myopic choroidal neovascularization (CNV) in a clinical setting. METHODS: This was a retrospective, monocentric, noncomparative analysis of 51 eyes of 51 patients with naïve juxtafoveal or subfoveal myopic CNV treated with intravitreal ranibizumab (IVR) on a pro re nata basis for at least 24 months. The patients' demographic data were recorded, including the best-corrected visual acuity (BCVA) measured with an ETDRS chart, location of the CNV, grade of myopic changes, central foveal thickness (CFT), and number of administered IVR. Outcome measures were to determine the changes in BCVA, identify the factors influencing the visual outcome, compare the best visual gain obtained for each treated eye with the final visual gain, and identify the cause of the relative decline in the visual acuity, when present. RESULTS: BCVA improved from 58.7 ± 19.0 letters at baseline to 66.3 ± 16.2 letters at the final visit (P = 0.001; mean visual gain: +7.6 ± 15.6 letters). Multivariate analysis did not identify any correlation between the visual gain and age, sex, grade of myopic fundus changes, CNV location, or initial protocol. The mean IVR number was 3.5 ± 2.8 injections (range 1-12; median 3) for a mean follow-up of 39.3 ± 11.3 months (range 24-69). Twenty-one eyes experienced a relative decline in BCVA during the follow-up, which was attributable in 16 cases to myopic atrophic changes. CONCLUSIONS: Intravitreal ranibizumab resulted in long-term efficacy in the treatment of myopic CNV. However, some eyes may present a long-term relative decline in their initial visual gain.

Intravitreal ranibizumab and/or dexamethasone implant for macular edema secondary to retinal vein occlusion.

PURPOSE: To investigate the outcome of intravitreal ranibizumab and/or dexamethasone implant treatment for treatment of macular edema (ME) secondary to central or branch retinal vein occlusion (CRVO or BRVO) in a clinical setting. METHODS: Retrospective analysis of consecutive patients followed for at least 6 months. Data recorded included the type of occlusion, initial and final visual acuity, and number of injections. RESULTS: Sixty-five patients were included, 26 had CRVO and 39 BRVO. Mean (± SD) follow-up duration was 16 (± 7.7) months. Twenty-four (36.9%) patients received ranibizumab in monotherapy, 19 patients (29.3%) dexamethasone in monotherapy, and 22 patients (33.8%) received successively both treatments. In dexamethasone-treated patients, mean (± SD) visual acuity gain was 5.8 ± 10.7 letters for BRVO and 16.8 ± 15.6 letters for CRVO. In ranibizumab-treated patients, mean (± SD) visual acuity gain was 9.2 ± 10 letters for BRVO and 18.2 ± 20.5 letters for CRVO. CONCLUSION: Both intravitreal ranibizumab and dexamethasone intravitreal implant could be used as first-line therapy for patients with ME secondary to retinal vein occlusion.

Bimonthly ranibizumab for neovascular age-related macular degeneration.

BACKGROUND/PURPOSE: Recently, aflibercept was proposed with a protocol of a bimonthly fixed regimen. Our purpose was to evaluate the results of this regimen in patients treated with ranibizumab. METHOD: We conducted a retrospective analysis of consecutive patients with naïve neovascular age-related macular degeneration treated with a bimonthly fixed regimen of intravitreal injections of ranibizumab after 3 monthly injections. Examination was performed every 4 weeks for 52 weeks, with the possibility of unscheduled rescue injections of ranibizumab. RESULTS: A total of 27 patients, 24 women and 3 men, aged from 68 to 90 years (mean: 81.2) were analyzed; 25 eyes (92.5%) lost <15 letters. Mean BCVA rose from 58.3 (range ± 12.9) to 66.7 (range ± 14.3) letters. The mean visual gain was 8.40 (range ± 13.2) letters; 11 patients (40.7%) gained ≥ 15 letters. The mean number of injections of ranibizumab was 8.77. CONCLUSION: Bimonthly intravitreal ranibizumab achieved satisfactory visual results. However, patients who required additional injections did not experience significant visual gain.

Inaugural severe vaso-occlusive retinopathy in systemic lupus erythematosus.

Purpose To report the case of a patient with an inaugural severe bilateral vaso-occlusive retinopathy due to systemic lupus erythematosus. Method Clinical examination, fundus pictures and fluorescein angiography were performed. Results A 26-year-old, healthy, African man presented with a meningo-encephalitic syndrome and a severe bilateral visual impairment. The fundus examination revealed multiple retinal vascular occlusions, and a fluorescein angiography showed retinal and choroidal ischemia bilaterally. In addition, based on the neurologic disorders, a pleuritis, a renal disorder and a hematologic disorder, systemic lupus erythematosus, was diagnosed. Conclusions Severe vaso-occlusive retinopathy in a 26-year-old man resulting in a significant visual loss as the initial manifestation of systemic lupus erythematosus. Central nervous system involvement during lupus might be more frequent in patients when serious retinal changes occur.
