PURPOSE: To report the results of switching treatment to vascular endothelial growth factor (VEGF) Trap-Eye (aflibercept) in neovascular age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV) refractory to anti-VEGF (ranibizumab and bevacizumab). METHODS: This is a retrospective study involving 32 eyes from 29 patients; 18 were cases of neovascular AMD and 14 were cases of PCV. The best-corrected visual acuity (BCVA) and central macular thickness (CMT) of spectral-domain optical coherence tomography were evaluated. RESULTS: BCVA and CMT improved from 0.58 to 0.55 (p = 0.005) and from 404 to 321 microm (p < 0.001), respectively, after switching to aflibercept. The 14 eyes that received 6 or more aflibercept injections remained stable at 0.81 to 0.81 and 321 to 327 microm (p = 1.0, 0.29), respectively, after 3 aflibercept injections. The 10 eyes that received 3 or more bevacizumab injections after 3 or more aflibercept injections worsened, from 0.44 to 0.47 and from 332 to 346 microm (p = 0.06, 0.05), respectively. The results showed similar improvement of BCVA and CMT in neovascular AMD and PCV. CONCLUSIONS: Aflibercept seems to be effective for improvement and maintenance of BCVA and CMT for neovascular AMD and PCV refractory to anti-VEGF. Switching from aflibercept back to bevacizumab treatment may not be a proper strategy.

PURPOSE: To evaluate the long-term outcomes of intravitreal anti-vascular endothelial growth factor (VEGF) monotherapy for patients diagnosed with submacular hemorrhage secondary to exudative age-related macular degeneration. METHODS: This retrospective, observational study included 49 patients (49 eyes) who initially presented with submacular hemorrhage associated with exudative age-related macular degeneration and who were followed-up for at least 24 months. Only eyes that were treated with intravitreal anti-VEGF monotherapy were included in the study. Best-corrected visual acuity (BCVA) measurements obtained at diagnosis, six months, and the final visit were compared. The associations of BCVA at the final visit with baseline BCVA, BCVA at six months, symptom duration, hemorrhage extent, and central foveal thickness were also analyzed. RESULTS: Over the course of follow-up (mean, 32.1 +/- 8.5 months), an average of 5.1 +/- 2.2 anti-VEGF injections were administered. Recurrent hemorrhage was noted in 13 eyes (26.5%). The mean logarithm of the minimal angle of resolution BCVA at diagnosis, six months, and the final visit were 1.40 +/- 0.52, 0.87 +/- 0.64, and 1.03 +/- 0.83, respectively. Both baseline BCVA (p = 0.012) and BCVA at six months (p < 0.001) were significantly associated with BCVA at the final visit. CONCLUSIONS: Improved visual acuity was maintained for more than two years with intravitreal anti-VEGF monotherapy. BCVA at six months is a useful clinical index to predict long-term visual prognosis.

The Diabetic Retinopathy Clinical Research Network (DRCR.net) performs studies on new treatments for diabetic retinopathy. This review aims to summarise recent findings from DRCR.net studies on the treatment of diabetic macular oedema. We performed a PubMed search of articles from the DRCR.net, which included all studies pertaining to the treatment of diabetic maculopathy. The main outcome measures were retinal thickening as assessed by central subfield thickness on optical coherence tomography and improvement of visual acuity on the Early Treatment Diabetic Retinopathy Study (ETDRS) chart. Findings from each study were divided into modalities of treatment, namely photocoagulation, bevacizumab, triamcinolone, ranibizumab and vitrectomy. While modified ETDRS focal/grid laser remains the standard of care, intravitreal corticosteroids or anti-vascular endothelial growth factor agents have also proven to be effective, although they come with associated side effects. The choice of treatment modality for diabetic macular oedema is a clinical judgement call, and depends on the patient's clinical history and assessment.

BACKGROUNDAge-related macular degeneration (AMD) is the leading cause of irreversible vision loss among the older population. In China, treatment of age-related ocular diseases is becoming a priority in eye care services. This study was to investigate the clinical characteristics and quality of life of Chinese patients with wet AMD and current treatment types, to evaluate short-term gains in different treatments, and to investigate associations between visual function and vision-related quality of life (VRQoL).

METHODSA prospective, observational, noninterventional study was conducted. Basic data were collected from patients with clinical diagnoses of wet AMD before clinical assessments at baseline. VRQoL was measured with the Chinese version of the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25). Correlations of the NEI VFQ-25 subscale scores with best-corrected visual acuity (BCVA) and between-group differences were analyzed.

RESULTSA total of 80 wet AMD patients were enrolled, with the mean age of 68.40 years. About one-quarter of wet AMD patients received intravitreal (IVT) ranibizumab treatment, and 67% of them were treated on a pro re nata basis. The visual acuity of patients treated with IVT ranibizumab at month 3 after treatment was significantly increased, whereas patients treated with traditional Chinese medicine achieved no significant improvement. Cronbach's α for the NEI VFQ-25 subscales ranged from 0.697 to 0.843. Eight subscale and overall composite scores were moderately correlated with the BCVA of the better-seeing eye. Significant differences in the overall NEI VFQ-25 scores and other subscales were observed between patients with BCVA in the better-seeing eye of less than 50 letters and the others.

CONCLUSIONSPatients treated with IVT ranibizumab experienced better vision improvement at short-term follow-up. The Chinese version of the NEI VFQ-25 is a valid and reliable tool for assessing the VRQoL of Chinese wet AMD patients.

PURPOSE: To compare pain scores of patients during intravitreal 27-gauge bevacizumab and 30-gauge ranibizumab injection procedures. METHODS: Seventy eyes of 70 patients who had not previously undergone intravitreal anti-vascular endothelial growth factor therapy were included in this study. Thirty-five patients received ranibizumab and 35 patients received bevacizumab. The diagnoses of the patients were: 27 age related macular degeneration, 15 diabetic macular edema, 9 diabetic vitreous hemorrhage, 6 central retinal vein occlusion, 11 branch retinal vein occlusion and 2 central serous chorioretinopathy. Bevacizumab (1.25 mg/0.05 mL) was injected into the vitreous cavity using a 27-gauge needle, and ranibizumab (0.5 mg/0.05 mL) was injected with 30-gauge needle. Patients were asked just after the injection to rate their perceived pain during the injection using the visual analogue scale (VAS) of 0 (no pain) to 10 (unbearable/worst pain). The average of these scores was used as the primary outcome. RESULTS: The VAS pain scores in the ranibizumab and bevacizumab groups were 1.06 +/- 0.91 (range, 0 to 3) and 1.94 +/- 1.55 (range, 0 to 7), respectively, a significant difference (p = 0.005). Patients <65 and > or =65 years of age in both the ranibizumab and bevacizumab groups were then compared. For patients <65, there was a significant difference in the average VAS pain scores between groups (p = 0.003). However, for patients > or =65 years, there was not a significant difference in the average VAS pain scores between groups (p = 0.238). Female and male patients in both ranibizumab and bevacizumab groups were also compared. For female patients, there was a significant difference in the average VAS pain scores between groups (p = 0.016), although not for male patients (p = 0.078). CONCLUSIONS: Thirty-gauge intravitreal injection is more comfortable than 27-gauge injection. Injection of bevacizumab with 30-gauge needle syringes may be more tolerable for patients.

BACKGROUNDIntravitreal ranibizumab injection is effecitve on treating myopic CNVs, but it could be a risk factor for developing more severe retinoschisis in eyes with preexisted retinoschisis and epiretinal membrane. This study aimed to explore the incidence and features of retinoschisis after intravitreal ranibizumab injection for myopic choroidal neovascularization.

METHODSEighty-three eyes of 81 patients with choroidal neovascularization secondary to pathologic myopia were treated with intravitreal ranibizumab injection. The best corrected visual acuity and optical coherence tomography (OCT) images were recorded at baseline and every month thereafter. Central retina thickness and maximal retina thickness were measured. The subjects were divided into three groups. Eleven eyes that had retinoschisis and epiretinal membrane were in group 1, six eyes that had simple epiretinal membrane were in group 2, and 66 eyes that had neither retinoschisis nor epiretinal membrane were in group 3. Six contralateral eyes in group 1 which had retinoschisis and epiretinal membrane but were not treated with intravitreal ranibizumab injection were set as the control group.

RESULTSSeven of the 11 eyes in group 1 developed more severe retinoschisis, the mean maximal retinal thickness increased from (380.28 ± 90.13) to (467.00 ± 70.20) µm (P < 0.05). The retinoschisis of all 6 eyes of the control group did not aggravate. Compared with the control group, the aggravation ratio of retinoschisis increased significantly (P < 0.05). No new onset of retinoschisis took place in group 2 and group 3.

CONCLUSIONIntravitreal ranibizumab injection may be a risk factor for aggravation of retinoschisis in eyes with preexisted retinoschisis and epiretinal membrane.

BACKGROUNDPathological myopia (PM) is the leading cause for choroidal neovascularization (CNV) in people below 50 years of age, the anti-vascular endothlial growth factor (VEGF) medicine is now available to treat CNV secondary to PM. This study aimed to observe the efficacy of intravitreal ranibizumab for PM associated with subfoveal or juxtafoveal CNV in Chinese patients.

METHODSFifty-four eyes of 52 consecutive patients were included, they treated with intravitreal ranibizumab 0.5 mg for PM associated with CNV. The best corrected visual acuity (BCVA) of Snellen chart, letters of ETDRS chart, retinal thickness, leakage of CNV lesion, and complications with surgery were analyzed pre- and post-treatment. Eligibility criteria included diopter ≥-8.0 D or eye axis ≥ 28 mm with fundus changes of PM (lacquer crack, optic disc atrophy, chorioretinal atrophy, posterior scleral staphyloma); CNV secondary to PM; subfoveal or juxtafoveal CNV.

RESULTSFor 54 affected eyes of 52 consecutive patients, the average BCVA of Snellen chart and letters of ETDRS chart were 0.29 and 30.4, respectively; fundus fluorescein angiography (FFA)/indocyanine green angiography (ICGA) showed CNV leakage, and average retinal thickness on optical coherence tomography (OCT) was 267.2 µm before treatment. Injections of ranibizumab ranged from 1 to 4 (mean 2.2). Follow-up time varied from 12 to 36 months (mean 31.9 months). At the last visit, the BCVA of Snellen chart was increased by three lines (mean 0.65) (P < 0.01); the letters of ETDRS chart were increased to 17.0 letters (mean 47.4, P < 0.01); the visual acuity increased more than 15 letters in 30 eyes (55.5%), decreased in 1 eye (1.9%); the retinal thickness on OCT images was decreased by 17.0 µm (mean 250.2 µm) (P = 0.082); no active leakage from the CNV lesion occurred in 18 eyes (33.3%), reduced leakage in 30 eyes (55.6%), and no change in 6 eyes (11.1%) as shown by FFA/ICGA. Increased retinoschisis was observed in one eye after the second injection.

CONCLUSIONSIntravitreal ranibizumab for neovascular PM was well tolerated in Chinese patients, with functional and anatomic improvements in a short-term study, while a long-term study is still needed.

BACKGROUNDPhotodynamic therapy (PDT) has been recommended as a main treatment for idiopathic choroidal neovascularization (I-CNV). But the visual results of PDT were inconsistent and variable, and PDT may bring severe damage to the retinal pigment epithelium and choriocapillaries. In recent years, intravitreal ranibizumab therapy, showing favorable visual outcomes, has developed as an advanced treatment for choroidal neovascularization (CNV). Although both methods have been reported to be effective in treating I-CNV, there is no detailed comparative report between the two methods. This study aimed to compare visual outcomes, retinal and choroidal thickness between intravitreal ranibizumab therapy and PDT in the treatment of I-CNV, and investigate the correlation of visual outcomes with retinal and choroidal thickness in each of the two groups.

METHODSThirty-seven eyes of 37 patients with I-CNV were involved in this study; 19 eyes were treated with intravitreal ranibizumab therapy and 18 eyes were treated with PDT. The best corrected visual acuity (BCVA) was recorded before and at each follow-up visit after treatments (logMAR). Enhanced-depth imaging optical coherence tomography (EDI-OCT) was used to evaluate the retinal structural changes, and to measure central retinal thickness (CRT) and central choroidal thickness (CCT).

RESULTSMean BCVA was 0.64 ± 0.27 in PDT group and 0.69 ± 0.22 in ranibizumab group at baseline (P = 0.55). When compared with the baseline, mean BCVA in PDT group was improved significantly at 3-month after PDT (0.41 ± 0.16, P = 0.002), then changed little (0.42±0.25 at 12-month, P = 0.88). Whereas mean BCVA in Ranibizumab group was improved significantly at each follow-up visit. It improved much more obviously in the first month and then remained stable. The mean BCVA in the ranibizumab group was significantly better at each follow-up visit than that in PDT (P < 0.05). When compared with the baseline, mean CRT in PDT group decreased significantly since 3-month visit, whereas mean CRT in ranibizumab group decreased significantly from 1-month visit. Mean CRT at 1-month and 3-month decreased much more in ranibizumab group than that in PDT group, almost in the same period as BCVA improving. When compared with the baseline, mean CCT did not change significantly at each follow-up visit in each group (P > 0.05). The CCT difference was not statistically significant between the two groups at each same time visit (P > 0.05). Mean BCVA was correlated with CRT, but was not correlated with CCT.

CONCLUSIONSBoth intravitreal ranibizumab therapy and PDT are effective for the treatment of I-CNV. It is obvious that ranibizumab therapy is significantly superior to PDT in improving BCVA and decreasing CRT. CRT decreases much more rapidly in ranibizumab group than in PDT group, simultaneously with visual improvement. CRT reduction has significant correlation with the visual outcomes in the recovery of I-CNV, whereas BCVA prognosis may have no correlation with CCT. CCT is not changed significantly after each of the treatments. Both PDT and ranibizumab therapy may have no significant effect on choroid.
