Purpose: We assess the effect of intravitreal anti-VEGF injections on tonographic outflow facility. Methods: Patients with age-related macular degeneration who had received unilateral intravitreal anti-VEGF injections were recruited into two groups, those with ≤10 and those with ≥20 total anti-VEGF injections. Intraocular pressure and tonographic outflow facility of injected and uninjected fellow eyes were measured and compared between groups. Risk factors for development of reduced outflow facility also were assessed. Results: Outflow facility was 12% lower in the injected eyes of patients who received ≥20 anti-VEGF injections, compared to contralateral uninjected eyes (P = 0.02). In contrast, there was no facility reduction for patients with ≤10 anti-VEGF injections (P = 0.4). In patients with ocular hypertension in the uninjected eye (IOP , 21 mm Hg, n = 5), the outflow facility of injected eyes was on average 46% lower (P = 0.01) than in the uninjected fellow eyes. This was ...

Purpose: To investigate subfoveal choroidal thickness (SFCT) changes following intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy and to identify clinical and choroidal parameters associated with visual outcome in eyes with myopic choroidal neovascularization (CNV). Methods: In 60 eyes of 54 patients who were treated with anti-VEGF injections for myopic CNV, SFCT was measured using enhanced depth imaging optical coherence tomography at baseline, at 1, 3, and 6 months after initial anti-VEGF therapy, and at the final visit. Subfoveal choroidal thickness was compared between visits in subgroups separated based on anatomic outcome, recurrence, or resolution. Univariate and multivariate regression analyses were performed to identify factors associated with final best-corrected visual acuity (BCVA). Results: At baseline, the mean SFCT was 47.6 ± 24.7 μm, significantly lower than that of the contralateral eyes (59.8 ± 34.4 μm, P = 0.022). The thickness significantly decreased ...

This report by a group of UK retina specialists and health professionals considers best practice recommendations for the management of sight-threatening neovascular age-related macular degeneration (nAMD), based on collective experience and expertise in routine clinical practice. The authors provide an update for ophthalmologists, allied healthcare professionals and commissioners on practice principles for optimal patient care and service provision standards. Refinement of care pathways for nAMD has improved access to intravitreal anti-vascular endothelial growth factor therapy but there are still variations in care and reported outcomes between clinic centres. Innovative organisational models of service provision allow providers to better match capacity with increasing demand. The authors review the recent NICE guideline for diagnosis and management of AMD, considerations for switching therapies and stopping treatment and need for regular monitoring of non-affected fellow eyes in patients with ...

PURPOSE: To compare the effect of 30-gauge versus 32-gauge needle size on postinjection reflux and immediate postinjection intraocular pressure (IOP(immed_post)) spikes in eyes injected with anti-vascular endothelial growth factor agents. METHODS: This was a prospective interventional case series of 65 eyes of 54 consecutive patients in a clinical practice setting who received intravitreal anti-vascular endothelial growth factor therapy. All eyes had preinjection IOP, IOP(immed_post), postinjection reflux, and axial lengths recorded. RESULTS: There was a higher incidence of postinjection reflux in eyes injected with 30-gauge (53%) compared with those injected with 32-gauge (13%, P = 0.0007). Among 34 eyes injected with 30-gauge, 16 eyes without appreciable postinjection reflux had mean IOP(immed_post) of 44.3 +/- 7.48 mmHg and mean IOP(immed_post) elevation of 29.6 +/- 2.10 mmHg, which was significantly higher than the 18 eyes with reflux (mean IOP(immed_post) of 18.8 +/- 7.15 mmHg and mean IOP(immed

Aim To quantify and correlate the morphological and functional effects of the recommended loading regimen with intravitreal ranibizumab in neovascular age-related macular degeneration (AMD).. Methods In a prospective, interventional clinical trial, 29 consecutive patients (29 eyes) with choroidal neovascularisation secondary to AMD received three initial monthly intravitreal injections of ranibizumab. During this loading regimen, best corrected visual acuity (BCVA) and microperimetry (MP) testing, as well as optical coherence tomography and fluorescein angiography (FA), were performed using a standardised protocol and the results correlated.. Results Significant morphological and functional therapeutic effects were observed as early as 1 week following the first treatment. Throughout the loading-dose period, central retinal thickness, including intraretinal cysts and subretinal fluid, decreased fast and significantly (p,0.01); pigment epithelial detachment resolved less rapidly. The mean leakage ...
PURPOSE To evaluate the effects of intravitreal bevacizumab and ranibizumab treatments in retinal angiomatous proliferation (RAP). METHODS Fifty patients affected by RAP were randomly assigned either to intravitreal bevacizumab injection (IVBI) or intravitreal ranibizumab injection (IVRI). After a loading phase including three consecutive monthly injections, the retreatment was administered in cases of persistent RAP. The primary outcome measures were the mean changes in BCVA between the two treatment groups, and the proportion of eyes gaining 1 and 3 lines at the end of the follow-up. Secondary outcomes included central macular thickness (CMT) changes and progression to more advanced stages of RAP. RESULTS Fifty patients affected by stage 1 and 2 RAP were recruited. Twenty-six and 24 patients received IVBI and IVRI, respectively. At the baseline, mean best corrected visual acuity (BCVA) values were 0.59 ± 0.21 (LogMAR ± SD, approximately corresponding to 20/80 Snellen Equivalent-SE) in IVBI group
PURPOSE: To report 1-year clinical outcomes of intravitreal ranibizumab treatment for choroidal neovascularization (CNV) due to age-related macular degeneration (AMD) and to identify predictive factors that may influence visual acuity (VA) outcomes in Korean patients.. METHODS: Sixty patients (64 eyes) with subfoveal CNV were followed up over 12 months after intravitreal injection (0.5 mg) of ranibizumab at baseline and subsequent injections on an as-needed basis. The VA outcomes over 12 months were compared with baseline VA and evaluated across subgroups based on sex, age, baseline VA, CNV size, CNV type, and presence or absence of systemic disease and prior photodynamic therapy.. RESULTS: VA improved or remained stable in 46 of 64 eyes (71.9%) at 12 months. Subgroup analysis showed that both baseline VA and CNV size influenced VA outcomes after ranibizumab treatment (P = 0.039, P = 0.042, respectively). However, the patients sex (P = 0.643), baseline age (P = 0.361), CNV type (P = 0.940), and ...
In this interventional clinical study, 181 eyes of 160 consecutive patients with active neovascular related macular degeneration meeting recommended criteria for inclusion and protocol criteria for anti-vascular endothelial growth factor therapy undergoing intravitreal bevacizumab monotherapy were evaluated. Data of treatment-naive eyes (Group 1, n = 114) were analyzed separately from eyes that had undergone previous photodynamic therapy plus intravitreal triamcinolone (Group 2, n = 67). Re-treatment criteria were based on clinical outcome following the official European label regimen. After 1 year of continuous service at an academic referral center, follow-up was performed in private practices in collaboration with the referral center. Main outcome parameters were best-corrected visual acuity and central retinal thickness ...
PURPOSE To investigate the efficacy of intravitreal injection of anti-vascular endothelial growth factor agents for Stage 4 retinopathy of prematurity. METHODS Retrospective case series study. The medical records of patients receiving intravitreal injection of anti-vascular endothelial growth factor agents for Stage 4 retinopathy of prematurity from January 2007 to May 2012 in Taipei Veterans General Hospital were reviewed. RESULTS A total of 13 eyes of 7 patients (3 boys and 4 girls) with Stage 4 retinopathy of prematurity were included. The mean gestational age and birth weight were 27.6 ± 2.6 weeks (range, 24.5-30.5 weeks) and 893.1 ± 293.2 g (range, 550-1422 g), respectively. The mean age at the time of injection was 38.2 ± 1.9 weeks (range, 36.0-41.5 weeks) postmenstrual age, and the mean follow-up period was 37.8 ± 19.5 months (range, 11.0-67.5 months). The active neovascularization regressed rapidly, and the anatomical outcomes were favorable in all patients. One eye developed recurrent
This is a 24 week, open-label, non-randomized, phase II study evaluating intravitreal ranibizumab dosed every 14 days in subjects with exudative macular degeneration who have persistent intraretinal or subretinal fluid despite chronic monthly anti-VEGF therapy (,6 months). Subjects must have had a minimum of 5 intravitreal anti-VEGF injections administered every 4-6 weeks in the 6 months preceding enrollment.. Consented, enrolled subjects will receive multiple open-label intravitreal injections of 0.5 mg ranibizumab administered every 14 days (± 3 days). Subjects who have resolution of fluid will convert to monthly ranibizumab for the remainder of the study. If fluid recurs, subjects will return to biweekly treatment.. Patients will be assigned to receive treatment with either ranibizumab vial or PFSs so that approximately 10 patients will be treated with each delivery method option, and syringe preparation time (SPT) will be measured by an assistant who will be observing the procedure and ...
PURPOSE OF REVIEW: Over the past few years, the results of many studies have highlighted the risks and benefits of intravitreal injection of a number of medications, the most common being triamcinolone, antivascular endothelial growth factor (VEGF) agents, antibiotics, antivirals, antifungals, and methotrexate. The purpose of this review is to highlight the complications associated with these injections. RECENT FINDINGS: Elevated intraocular pressure and glaucoma are the most common complications of intraocular triamcinolone. There is also an increased incidence of cataract formation/progression over time. The immunosuppressive effect of triamcinolone does not appear to increase the risk of endophthalmitis. Recent reports suggest that intravitreal anti-VEGF injections have a low complication rate. Similarly, antimicrobials also have low rates of injection-associated complications. SUMMARY: Intravitreal injections play a critical role in daily ophthalmic practice. The overall risk of endophthalmitis and

To investigate the pharmacokinetics of bevacizumab in rabbits for three different routes of administrations: intravitreal injection, subconjunctival injection, and eye drops. METHODS. Pigmented rabbits received bevacizumab in one eye by topical eye drops (1.25 mg/0.05 mL six times daily for the first 7 days), single subconjunctival injection (1.25 mg/0.05 mL), or single intravitreal injection (1.25 mg/0.05 mL). Bevacizumab concentrations in plasma and ocular tissues in the treated and fellow eyes were determined by sandwich enzymelinked immunosorbent assay at 1, 2, 4, and 12 weeks after administration. RESULTS. After intravitreal injection in ...
Methods Seven of 89 treatment-naïve nAMD eyes showed persistent choroidal neovascular membrane (CNV) activity throughout a spectral domain optical coherence tomography (SD-OCT)-driven pro re nata (PRN) regimen of intravitreal ranibizumab injections over 28±4 months. The treatment was switched to PRN aflibercept injections and patients were followed for another 15±2 months. A total of 160 aqueous humour specimens were collected before the intravitreal injections, and their VEGF-A concentrations were assayed by Luminex multiplex bead analysis (Luminex, Austin, Texas, USA). Intraocular VEGF-A concentrations were correlated to CNV activity shown by SD-OCT. ...
DISCUSSION. We observed that nine of the 12 eyes developed RPE tears during the treatment of choroidal neovascularization with ranibizumab injections. We continued to inject intravitreal ranibizumab after the development of RPE tears. After all injections, two of the 12 eyes appeared to be stable, nine of the 12 eyes showed improvement, and only one eye showed worsening of visual acuity at the end of the follow-up periods. At the last follow-up visits, however, the visual acuity had decreased in the patients with a high degree of tears, but the decrease was not statistically significant. According to our experience, continuation of anti-VEGF injections for patients who developed RPE tears during injection therapy appears to be necessary. In our study population, the heights of the PEDs were ,400 microns, and PEDs in seven of the eight eyes had irregular contours.. The pathogenesis of RPE tears is not fully understood. Contraction of the choroidal neovascularization under the weak RPE, increased ...

The objective of this study is to compare the effectiveness and costs of 1.25 mg of bevacizumab to 0.5 mg ranibizumab, given as monthly intravitreal injections during 6 months. This will be a randomized, controlled, double masked, clinical trial in 246 patients in seven academic trial centres in The Netherlands. The study population consists of patients 18 years of age or higher with diabetic macular and a best corrected visual acuity BCVA score between 78 and 20 letters in the study eye. The primary outcome measure will be the change in best-corrected visual acuity (BCVA) in the study eye from Baseline to Month 6. Secondary outcomes will be amongst others the proportion of patients with a gain of 15 letters or more and/or a BCVA of 20/40 or more at 6 months, and the costs and costs per quality adjusted life-year of the two treatments ...
At that point our review of the literature indicated poor response of iatrogenic CNVM to laser photocoagulation, photodynamic therapy, and surgical removal of subretinal fluid.(2-6) Because intravitreal bevacizumab injections had been used effectively to treat CNVM secondary to other retinal diseases, it was decided that this treatment would be used in the present case. However, intravitreal bevacizumab injections are not readily available in our hospital, and strict criteria are applied before approval of their use. Treatment was started 5 weeks after the diagnosis of CNVM. Intravitreal bevacizumab injections in the right eye were administered every 6 weeks over a 6-month period, but visual acuity failed to improve. Nine months following surgery, a disciform scar developed and treatment was discontinued, at which time visual acuity in the right eye was counting fingers ...

It is most pertinent to note that patients under our care often have multiple ocular co-morbidities, e.g. ARMD and glaucoma. The high volume nature of our wARMD treatment clinics means that other co-morbidities could be overlooked. Glaucoma is one of the commoner conditions and is especially important to note since any situation that leads to poor IOP control can obviously compromise the overall vision [18,19]. Therefore, we must take care not to cause deterioration of one condition whilst trying to treat another. Studies have demonstrated not only transient but also sustained IOP elevations beyond 1 month in glaucoma patients following anti-VEGF injections [14,15,20-25]. This is of great concern since even if the pre-injection glaucoma control is satisfactory (as in our study) this could become compromised after IVTL despite continuation of the same glaucoma treatment, in up to 33% of patients. Therefore, it is most important to treat any IOP elevations in this group of patients aggressively at ...
With the approval of ranibizumab (Lucentis) in 2006 and the off-label use of bevacizumab (Avastin) ophthalmologists are treating neovascular macular degeneration and other retinal neovascular diseases, intravitreal injections have become routine in practices specializing in retinal diseases and in many general ophthalmology practices. Even though the rate of adverse side effects is low8,9 the number of intravitreal injection is so large that even these low rates result in significant numbers of patients suffering adverse events. In 2008, the number of intravitreal injections billed to Medicare was over one million in the US12 and it may now have reached three million; with three million intravitreal injections at the rate of 2 % adverse events would affect 60,000 patients in the US alone. Some complications associated with intravitreal injections, such as conjunctival hemorrhage, retinal tears, and retinal detachment are caused by the injection through the sclera without the ability to visualize ...

Although uncommon, sustained intraocular pressure increase after intravitreal ranibizumab injections is possible. Treating ophthalmologists should check pre-injection IOP at each patient visit.
10 patients were included, 6 females and 4 males, with a mean age of 62 years old (ranging from 59 to 66). All eyes were previously treated with grid laser and a mean of 4 intravitreal injection of bevacizumab (ranging from 1 to 7). At last follow up, vitrectomized eyes showed a mean BCVA gain of 1 line ETDRS (ranging from -2 and +2 lines) and a mean foveal thickness reduction of -57% (ranging from -41 to -79%), starting from a mean foveal thickness of 606 µm (ranging from 380 to 819 µm), no intravitreal injection with antiVEGF was required. All fellow eyes required intravitreal injections of ranibizumab (mean number of 4, ranging from 1 to 7), the mean foveal thickness at baseline was 356 µm (ranging from 234 to 558 µm) and the mean BCVA gain after each intravitreal injection was +2 ETDRS lines (ranging from 0 to +4 ...
There has been a rapid rise in the use of intravitreal injections, such as anti-vascular endothelial growth factor (anti-VEGF) agents, performed over the past few years for the treatment of ocular neo
Intravitreal injection of anti-VEGF (vascular endothelial growth factor) antibodies or antibody fragments has been shown to be a highly effective treatment for neovascular age-related macular degeneration (wet AMD). The ocular half-life (t1/2) of these large molecules, determined in ocular fluids or derived from serum levels, varies with molecular size and is larger in humans than in preclinical animal species. The high affinity binding of VEGF to these molecules lowers the free concentration of VEGF and reduces its occupancy on VEGF receptors in ocular tissues. To understand the biophysical determinants of t1/2 for anti-VEGF antibodies and the time-course of VEGF in ocular fluids, we developed a mechanistic model of intravitreal pharmacokinetics (IVT PK) for anti-VEGF antibodies and combined it with a mechanistic model of the pharmacodynamics (RVR PD) of VEGF suppression by ranibizumab, an anti-VEGF recombinant, humanized monoclonal antibody fragment (Fab). Our IVT PK model predicts that the ocular t1
Eighteen eyes of 15 patients who fulfilled the inclusion criteria were included in the study. The distribution of baseline OCT findings was: minimal SRF (6 eyes), minimal IRF (3 eyes), pigment epithelial detachment (PED) combined with minimal IRF (2 eyes), PED combined with minimal SRF (7 eyes). Two (11%) eyes developed signs of active disease within the follow up period and underwent intravitreal anti-VEGF injections. The interval between baseline and onset of active, wet AMD was 8 months in one eye and 18 months in the second. Mean (SD) baseline BCVA for the study eyes was 0.21(0.22) improving to 0.16 (0.19) at final follow up. The corresponding BCVA for the non treated eyes was 0.22 (0.23) at baseline and 0.15 (0.18) at final follow up (p=0.012). Final BCVA was associated with greater baseline BCVA ( ...

Ophthalmologists believe that the risk of these complications mentioned above is very low. Patients receiving Avastin for eye conditions are healthier than the cancer patients and receive a significantly smaller dose (0.05ml), delivered only to the cavity of their eye. While there are no FDA-approved studies about the use of Avastin in the eye that prove it is safe and effective, there are ongoing trials of a similar drug (Lucentis) as well as studies of patients receiving Avastin "off-label".. One study of patients who received Avastin through an intravenous infusion reported only a mild elevation in blood pressure. Another study of patients treated you like you will be with intravitreal Avastin (that is Avastin injected into the eye) did not have these elevations or the other serious problems seen in the patients with cancer.. However the benefits and risks of intravitreal Avastin for eye conditions are not fully known. In addition whenever a medication is used in a large number of patients, a ...
AAVIATE is a multi-center, open-label, randomized, active-controlled, dose-escalation trial that will evaluate the efficacy, safety and tolerability of suprachoroidal delivery of RGX-314 using the SCS Microinjector, a targeted, in-office route of administration. The trial is expected to enroll approximately 40 patients with severe wet AMD across two cohorts. Patients in each cohort will be randomized to receive RGX-314 versus monthly 0.5 mg ranibizumab intravitreal injection at a 3:1 ratio, and two dose levels of RGX-314 will be evaluated: 2.5x1011 GC/eye and 5x1011 GC/eye. Patients will not receive prophylactic immune suppressive corticosteroid therapy before or after administration of RGX-314. The primary endpoint of the trial is mean change in vision in patients dosed with RGX-314, as measured by best corrected visual acuity (BCVA), at Week 40 from baseline, compared to patients receiving monthly injections of ranibizumab. Other endpoints include mean change in central retinal thickness (CRT) ...
