Intravitreal bevacizumab in inflammatory ocular neovascularization

Intravitreal immunotherapy in non-infectious uveitis: an update

INTRODUCTION

In the past several years, there have been numerous advances in pharmacotherapeutics for the management of uveitis and other ocular inflammatory diseases, including newer therapeutic agents and ocular drug delivery systems. One of the most attractive modes of drug delivery is the intravitreal route since it has proven to be safe and efficacious and prevents unwanted systemic adverse events related to the agent.

AREAS COVERED

In this review, intravitreal delivery of various pharmacotherapeutic agents for noninfectious uveitis has been described. An extensive review of the literature was performed using specific keywords on the PubMed database to identify clinical studies employing various pharmacotherapeutic agents with intravitreal drug delivery for noninfectious uveitis. The mode of action, safety, efficacy, and tolerability of these drugs have also been elucidated.

EXPERT OPINION

Several agents, including biologic response modifier agents, have been found to be safe and efficacious for various indications of uveitis, such as cystoid macular edema, active uveitis, and other conditions such as retinal vasculitis and vitreous haze. The use of intravitreal biological therapies, especially infliximab, has been fraught with potential safety signals such as photoreceptor toxicity. However, pharmacotherapeutic agents such as corticosteroids and anti-vascular endothelial growth factor agents are now widely used in the clinical management of uveitis and its complications.

Efficacy and safety of Aflibercept for the treatment of inflammatory choroidal neovascularization: The ALINEA study

PURPOSE

To evaluate mean change in best-corrected visual acuity (BCVA) at 52 weeks in patients with inflammatory choroidal neovascularization (CNV) treated with aflibercept.

METHODS

We conducted a prospective non-comparative open-label trial. Following one mandatory intravitreal injection of aflibercept, patients were treated under a pro re nata (PRN) dosing regimen with monthly visits.

RESULTS

A total of 19 patients were included, but one presented exclusion criteria; 16 patients were followed for the whole 52-week study, and data for the primary endpoint analysis were available for 14. At baseline, mean BCVA and mean central retinal thickness (CRT) were 64.53 (±19.64) letters and 351.79 (±97.77) μm, respectively. At 52 weeks, the mean change in BCVA was +9.50 (±12.90) letters [95%CI = +2.05-+16.95]. One patient had lost more than 15-letters at 24 weeks, and another one at 52 weeks. CRT change was -62.77 (±100.73) μm at 24 weeks and -66.53 (±97.47) μm at 52 weeks. There was a mean number of 3.56 (±3.29) intravitreal injections at 52 weeks (min = 1; max = 12). No serious ocular adverse events related to the treatment were reported.

CONCLUSIONS

Our study shows that aflibercept is clinically effective, both anatomically and functionally in the treatment of inflammatory CNV. Following the first injection, the PRN strategy appears sufficient for treating most choroidal neovessels.

Review for Diagnostics of the Year: Inflammatory Choroidal Neovascularization – Imaging Update

Inflammatory choroidal neovascularization (iCNV) is a rare complication of uveitis but is a major cause of vision compromise in affected patients. Fluorescein angiography (FA) has been the gold standard for diagnosis. However, it is an invasive modality and when used alone, it might be difficult to distinguish iCNV from inflammatory lesions. Optical coherence tomography (OCT) is a noninvasive and rapid imaging modality that can provide additional features to diagnose iCNV. OCT angiography (OCTA) uses intrinsic motion contrast to visualize flow and is useful to distinguish iCNV from inflammatory lesions. However, its role in evaluating iCNV activity and treatment response is still unclear and more studies are required to reach consensus. In conclusion, the use of data from multimodal imaging is necessary to identify and promptly treat iCNV, thus preserving patient vision.

Intravitreal Antivascular Endothelial Growth Factor Treatment for Inflammatory Choroidal Neovascularization in Noninfectious Uveitis

PURPOSE

To compare visual outcome and recurrence rates of eyes with noninfectious inflammatory choroidal neovascularization (CNV) treated with or without anti-vascular endothelial growth factor (VEGF) injections and immunosuppression.

DESIGN

Retrospective, nonrandomized clinical study.

METHODS

Participants: Patients with CNV secondary to noninfectious inflammatory causes who attended uveitis clinics at Moorfields Eye Hospital between January 2000 and April 2016. Data were gathered from the clinical notes of all subjects examined in clinic.

MAIN OUTCOME MEASURES

change in best-corrected visual acuity (BCVA), mean time to CNV recurrence, moderate vision loss (≤20/50), and severe vision loss (≤20/200).

RESULTS

A total of 166 patients (204 eyes) with noninfectious inflammatory CNV were included in this study with a median follow-up of 6.9 years (interquartile range: 2.9-11.7; 1652 eye-years). The mean BCVA at the time of CNV diagnosis was 0.38 ± 0.05 logarithm of the minimum angle of resolution (logMAR) (Snellen equivalent 20/47) in the eyes that received the first-line anti-VEGF treatment and 0.44 ± 0.03 logMAR (Snellen equivalent 20/55) in the eyes on other treatment modalities (P = .39). Eyes treated first with anti-VEGF (n = 55) received the mean of 4.35 ± 0.53 injections and showed a statistically significant improvement in vision at all time points (P < .001) except for a 5-year visit (P = .25). The rest of the eyes demonstrated no significant change in vision throughout follow-up (all P > .05). At the final visit, the mean BCVA was 0.26 ± 0.11 logMAR (Snellen equivalent 20/36) in the former and 0.35 ± 0.06 logMAR (Snellen equivalent 20/44) in the latter. The mean time to CNV recurrence was 186 ± 15.1 months, and the risk was significantly reduced by treatment with oral corticosteroids (adjusted hazard ratio = 0.32, confidence interval: 0.17-0.59, P < .001) or anti-VEGF injections (adjusted hazard ratio = 0.31, confidence interval: 0.18-0.52, P < .001).

CONCLUSIONS

Eyes that developed inflammatory CNV were at risk of vision loss. Those receiving early anti-VEGF injections achieved a better visual outcome and had a reduced risk of CNV recurrence. Oral corticosteroids also had an effect that reduces the risk of recurrence in eyes previously treated.

Long-Term Analysis of Clinical Features and Treatment Outcomes of Inflammatory Choroidal Neovascularization

PURPOSE

To investigate the long-term clinical features and treatment outcomes of patients with inflammatory choroidal neovascularization (CNV) treated with intravitreal anti-vascular endothelial growth factor (anti-VEGF).

DESIGN

Retrospective, interventional, consecutive case series.

METHODS

Sixty-five eyes of 65 patients with inflammatory CNV treated with anti-VEGF injections and followed up at least 12 months were included. Retrospective chart review was conducted at a single tertiary referral center.

RESULTS

Study participants were followed up for 60.6 ± 42.8 (range, 16-160) months. Mean age was 33.4 ± 10.8 years, and mean refractive error was -3.94 ± 1.35 D in spherical equivalent. Final best-corrected visual acuity (BCVA) was 0.21 ± 0.20 logMAR after treatment. Patients were treated with bevacizumab (76.9%), ranibizumab (4.6%), aflibercept (3.1%), and drug combinations (15.4%). Systemic corticosteroid or immunosuppressant use was not correlated with visual outcome, required number of anti-VEGF injections, and recurrence. Commonly occurring optical coherence tomography (OCT) features included ellipsoid zone disruption, choroidal hypertransmission, retinal pigment epithelium atrophy or absence (RPEA), intraretinal hyperreflective foci (HRF), choroidal vessel engorgement, focal choroidal excavation, and irregular vascular loops (on OCT angiography). RPEA after treatment (β = 0.238, P = .036) and BCVA (β = 0.267, P = .029) showed significant correlation with final BCVA. A total of 28 patients (43.1%) experienced recurrence; intraretinal HRF after treatment was the single risk factor for recurrence (odds ratio = 2.712, P = .031).

CONCLUSIONS

Inflammatory CNV recurrence showed higher rates over time after anti-VEGF treatment than previously reported, even though the overall visual outcome was good. Baseline BCVA and RPEA after treatment are significant predictors for visual outcome. Intraretinal HRF after anti-VEGF treatment suggests the potential risk of recurrence.

Inflammatory Choroidal Neovascular Membranes: Clinical Profile, Treatment Effectiveness, and Visual Prognosis

Purpose

To characterise a sample of patients with inflammatory choroidal neovascularization (I-CNV), including clinical profile, underlying aetiology and its course, treatments performed, associated clinical response, and visual prognosis.

Methods

Retrospective analysis of patients with a diagnosis of I-CNV followed at the Ophthalmology Department of Centro Hospitalar Universitário de São João (CHUSJ). Clinical and visual outcomes were classified according to the difference in visual acuity after treatment.

Results

Twenty eyes from 17 patients were analysed (11 female and 6 male patients, mean age 41.90 ± 16.457 years at CNV diagnosis). Punctate inner choroidopathy/multifocal choroiditis was the predominant inflammatory aetiology (10 patients, 58.82%). Median follow-up time was 46 months (range 10 to 188 months). Neovascularization was treated with intravitreal anti-VEGF injections (bevacizumab, aflibercept, and ranibizumab), and inflammation with anti-inflammatory/immunosuppressive therapy (oral, intravenous, and/or intravitreal corticosteroids; oral cyclosporine or methotrexate). Intravitreal anti-VEGF agents had a median number of 7.00 injections (IQR, 4.25 to 29.00). Visual acuity among 20 eyes had a mean gain of 15.10 ± 12.998 ETDRS letters after anti-VEGF treatment (p=0.000051). According to our classification, 16 had an improved outcome (80.00%), 3 had a stable outcome (15.00%), and 1 had a worsened visual outcome (5.00%). In addition, 13 eyes (65.00%) had a final VA equal to or greater than 65 letters. Recurrence was seen in 3 eyes (15.00%). Complications included cataract (6 patients) and ocular hypertension (4 patients).

Conclusion

A combined approach with anti-VEGF agents and anti-inflammatory therapy was effective in I-CNV treatment, and an overall good visual prognosis was attainable. Intensive follow-up was fundamental in the management of both the primary inflammatory and secondary neovascular conditions.

Twenty-four-month outcomes of inflammatory choroidal neovascularisation treated with intravitreal anti-vascular endothelial growth factors: a comparison between two treatment regimens

Background and aim

There is still no established treatment regimen for eyes with inflammatory choroidal neovascularisation (iCNV) treated with intravitreal anti-vascular endothelial growth factor (VEGF) injections. This study compared the 24-month outcomes of two treatment regimens of anti-VEGF injections in eyes with iCNV.

Methods

Eyes with iCNV treated with anti-VEGF injections were divided into two groups: eyes treated with a loading phase of 3 monthly injections and then re-treated as needed (LOADING group) and eyes treated as needed from the beginning (PRN group). Visual acuity (VA), number of injections and iCNV recurrences at 24 months were compared between the groups.

Results

Eighty-two eyes were included, 42 in the LOADING and 40 in the PRN group. Baseline VA (mean(SD)) was 57.3 (15.8) letters in the LOADING vs 60.7 (15.6) letters in the PRN group (p=0.32). The VA (mean (95% CI)) increased at 3 months (+14.8 (10.6 to 18.9) and +11.2 (6.4 to 16) letters in the LOADING and PRN group, respectively) and remained significantly higher than baseline over the entire follow-up in both groups (all p<0.001). At 24 months, there was no difference in VA between the LOADING and PRN group (72.3 (14.0) vs 74.7 (11.3) letters, p=0.36) but the LOADING group received significantly more injections (median (Q1–Q3)) than the PRN (4.5 (3–7) vs 2.5 (2–3.2), p<0.0001). The iCNV recurrences were similar in both groups.

Conclusions

iCNV responded well to anti-VEGF with significant and sustained VA improvement. The loading phase did not confer any advantage in terms of outcomes. PRN regimen from the beginning was as effective as more intensive treatment.

One-year outcomes of anti-vascular endothelial growth factor therapy in peripapillary choroidal neovascularisation

PURPOSE

To report the visual and anatomical outcomes in eyes with peripapillary choroidal neovascularisation (CNV) through 12 months.

METHODS

This was a multicentre, retrospective, interventional case series which included treatment-naïve cases of peripapillary choroidal neovascular membrane (CNVM) with a minimum follow-up of 12 months. Multimodal imaging which comprised optical coherence tomography (OCT), fluorescein angiography and/or indocyanine green angiography was performed at baseline and follow-up visits. OCT parameters included central macular thickness (CMT), subfoveal choroidal thickness (SFCT) and retinal and choroidal thickness at site of CNV. Patients were treated with anti-vascular endothelial growth factors (VEGF) on pro re nata protocol, photodynamic therapy, laser photocoagulation or a combination. Main outcome measures were change in best corrected visual acuity (BCVA) and OCT parameters.

RESULTS

A total of 77 eyes (74 patients; mean age: 61.9±21.8 years) with a mean disease duration of 9.2±14.1 months were included. BCVA improved significantly from 0.55±0.54 logMAR (20/70) at baseline to 0.29±0.39 logMAR (20/40) at 12 months (p<0.001) with a mean of 4.9±2.9 anti-VEGF injections. CMT, SFCT and retinal thickness at site of CNVM reduced significantly (p<0.001, <0.001 and 0.02, respectively) through 12 months. The most common disease aetiologies were neovascular age-related macular degeneration, and idiopathic, inflammatory and angioid streaks. Age (p=0.04) and baseline BCVA (p<0.001) were significant predictors of change in BCVA at 12 months.

CONCLUSION

Peripapillary CNVM, though uncommon, is associated with diverse aetiologies. Anti-VEGF agents lead to significant visual acuity and anatomical improvement in these eyes over long term irrespective of the aetiology.

EFFICACY AND SAFETY OF RANIBIZUMAB FOR THE TREATMENT OF CHOROIDAL NEOVASCULARIZATION DUE TO UNCOMMON CAUSE: Twelve-Month Results of the MINERVA Study

Supplemental Digital Content is Available in the Text.

Ranibizumab was effective in treating choroidal neovascularization of various etiologies, with a treatment effect of +9.9 letters versus sham at Month 2 and a mean gain of 11.0 letters from baseline to Month 12. The beneficial effects of ranibizumab were observed across all etiology subgroups.

Purpose:

To evaluate the efficacy and safety of ranibizumab 0.5 mg in adult patients with choroidal neovascularization because of an uncommon cause enrolled in the 12-month MINERVA study.

Methods:

In this Phase III, double-masked study, adult (≥18 years) patients (N = 178) were randomized 2:1 to receive either ranibizumab (n = 119) or sham (n = 59) at baseline and, if needed, at Month 1 and open-label individualized ranibizumab from Month 2. Best-corrected visual acuity change from baseline to Month 2 (primary endpoint) and Month 12, treatment exposure, and safety over 12 months were reported. Subgroup analysis was conducted on five predefined choroidal neovascularization etiologies (angioid streak, postinflammatory, central serous chorioretinopathy, idiopathic, and miscellaneous).

Results:

Ranibizumab showed superior efficacy versus sham from baseline to Month 2 (adjusted least-squares mean best-corrected visual acuity: +9.5 vs. −0.4 letters; P < 0.001). At Month 12, the mean best-corrected visual acuity change was +11.0 letters (ranibizumab) and +9.3 letters (sham). Across the 5 subgroups, the treatment effect ranged from +5.0 to +14.6 letters. The mean number of ranibizumab injections was 5.8 (ranibizumab arm) with no new ocular or nonocular adverse events.

Conclusion:

Ranibizumab 0.5 mg resulted in clinically significant treatment effect versus sham at Month 2. Overall, ranibizumab was effective in treating choroidal neovascularization of various etiologies with no new safety findings.

Inflammatory optic disc neovascularisation managed with oral steroids/immunosuppressants and intravitreal ranibizumab

Inflammatory optic disc neovascularisation (NVD) has been treated with periocular or systemic steroids, immunosuppressants, panretinal photocoagulation and bevacizumab. However, the role of intravitreal ranibizumab in inflammatory NVD has not been explored in the peer-reviewed indexed literature. In case 1, NVD and associated subhyaloid haemorrhage showed rapid and dramatic regression after intravitreal ranibizumab. Recurrence was noted 8 weeks after injection which was managed by oral steroids. In case 2, intravitreal ranibizumab led to partial resolution of NVD. The addition of steroids, azathioprine and panretinal photocoagulation led to further fibrosis of the neovascularisation. Ranibizumab may be an important adjunct to anti-inflammatory therapy in the management of inflammatory NVD.

Efficacy and safety of conbercept as a primary treatment for choroidal neovascularization secondary to punctate inner choroidopathy

Background

To evaluate the efficacy and safety of intravitreal conbercept (KH902) as the primary treatment of choroidal neovascularization secondary to punctate inner choroidopathy.

Methods

This study was a retrospective, consecutive, observational case series. We reviewed medical records of 16 eyes (16 patients) with naive subfoveal or juxtafoveal choroidal neovascularization secondary to punctuate inner choroidopathy that were treated with intravitreal conbercept injections. All patients completed at least six months of follow-up. Best-corrected visual acuity (BCVA) was measured, and anatomical features were assessed with fluorescein angiography, indocyanine green angiography, and optical coherence tomography.

Results

At the month-6 follow-up visit, best-corrected visual acuity improved from 0.70 ± 0.36 (with approximate Snellen equivalent of 20/100) to 0.44 ± 0.25 (20/50 in Snellen) logarithm of the minimum angle of resolution (logMAR) (P = 0.003). Mean improvement of vision was 2.6 lines, with 50% treated eyes (8 eyes of 16) showing an improvement of ≥3 lines and 62.5% (10 eyes of 16), obtaining an improvement of ≥2 lines; all 16 eyes had stable or improved vision. Mean central retinal thickness decreased from 294.94 ± 102.68 μm to 206.56 ± 61.71 μm (P = 0.005). Fifteen eyes (93.75%) showed absence of CNV leakage at the end of the study period. No conbercrept-related systemic or ocular adverse events were observed.

Conclusion

Intravitreal injection of conbercept significantly improved visual and anatomical outcomes in choroidal neovascularization secondary to punctate inner choroidopathy over a 6-month follow-up period.

Intravitreal anti-VEGF treatment for choroidal neovascularization secondary to punctate inner choroidopathy

PURPOSE

To assess the outcome of patients with choroidal neovascularization (CNV) secondary to punctate inner choroidopathy (PIC) receiving intravitreal anti-VEGF (vascular endothelial growth factor) injections.

METHODS

Sixteen eyes of 16 patients diagnosed with CNV secondary to PIC were retrospectively assessed.

RESULTS

Eleven women and five men with a mean age of 35 years (SD 11, range 16-56 years) received intravitreal anti-VEGF for PIC-related CNV. On average, 3.5 injections (SD 2.7, range 1-9) were given per eye. Thirteen eyes were treated with bevacizumab, two eyes with ranibizumab and one eye received both substances. The mean follow-up was 15 months (SD 11, range 6-40 months). BCVA improved in eight eyes (mean Δ +2.8 lines), remained stable in four eyes and decreased in four eyes (mean Δ -4.3 lines).

CONCLUSIONS

CNV development is a frequent complication of PIC. Intravitreal anti-VEGF therapy seems to be safe and effective for PIC-related CNV.

Management of noninfectious posterior uveitis with intravitreal drug therapy

Uveitis is an important cause of vision loss worldwide due to its sight-threatening complications, especially cystoid macular edema, as well as choroidal neovascularization, macular ischemia, cataract, and glaucoma. Systemic corticosteroids are the mainstay of therapy for noninfectious posterior uveitis; however, various systemic side effects can occur. Intravitreal medication achieves a therapeutic level in the vitreous while minimizing systemic complications and is thus used as an exciting alternative. Corticosteroids, antivascular endothelial growth factors, immunomodulators such as methotrexate and sirolimus, and nonsteroidal anti-inflammatory drugs are currently available for intravitreal therapy. This article reviews the existing literature for efficacy and safety of these various options for intravitreal drug therapy for the management of noninfectious uveitis (mainly intermediate, posterior, and panuveitis).

Antivascular Endothelial Growth Factor Monotherapy for Choroidal Neovascularization Associated With Retinochoroidal Coloboma: Case Series

PURPOSE

This study aimed to report the outcomes of antivascular endothelial growth factor (anti-VEGF) monotherapy for choroidal neovascularization (CNVM) associated with retinochoroidal coloboma (RCC).

DESIGN

A retrospective case series.

METHODS

This was a case series of 3 eyes with CNVM associated with RCC that presented to the LV Prasad Eye Institute, Hyderabad, India, between January 2006 and January 2014. Reported data included demographics, preoperative details (symptoms, duration of symptoms, and visual acuity), treatment methods, and postoperative details (visual acuity, follow-up, and recurrence). These data were compared with 9 other cases previously reported in the literature.

RESULTS

Three eyes of 3 patients (2 females and 1 male) were included, with a mean age of 18.3 years (range, 2-32 years). The preoperative best corrected visual acuity ranged from 20/540 to 20/100. All 3 eyes were treated with intravitreal bevacizumab injections. The mean number of injections was 2.0 (range, 1-3) and mean duration of follow-up was 12 months (range, 4-24 months) with no recurrence. The best corrected visual acuity at the last follow-up was improved, ranging from 20/310 to 20/60.

CONCLUSIONS

In view of good treatment outcomes with no recurrence and a lesser number of injections, anti-VEGF monotherapy could be considered as treatment for coloboma-associated CNVM.

Diagnostic Challenges in Inflammatory Choroidal Neovascular Membranes

PURPOSE

To describe the clinical presentations of inflammatory choroidal neovascular membranes (CNVMs) and factors leading to their delayed diagnosis.

METHODS

Retrospective analysis of chart records and digital images of 60 patients (73 eyes) with inflammatory CNVM (January 1998 to December 2013) to obtain demographic and clinical details, particularly the time of the first documentation of inflammatory CNVM by the uveitis specialist, time of its actual appearance on digital images, and the earliest clinical indicators of a CNVM.

RESULTS

In total, 14 (19.2%) eyes had a delayed diagnosis of inflammatory CNVMs, of which five developed significant visual loss. The earliest clinical indicators of CNVM that were overlooked initially due to their subtle appearance, included a tiny subretinal hemorrhage (five eyes), peripapillary halo/fluid/scar (eight eyes), and a subfoveal scar (one eye). The causes of uveitis in these eyes included Vogt-Koyanagi-Harada disease (five eyes, 35.7%), tubercular uveitis (five eyes, 35.7%), idiopathic (three eyes, 21.4%), and sympathetic ophthalmia (one eye, 7.1%). Presence of significant background fundus scarring, sunset glow fundus, visually significant cataract, poorly dilating pupil, media haze due to vitritis, cystoid macular edema, and multiple chorioretinal scars in these eyes probably predisposed to delayed detection of an underlying CNVM.

CONCLUSIONS

A high index of suspicion and comparison of serial fundus photographs to identify the earliest clues of inflammatory CNVMs are important to prevent diagnostic delays and poorer outcomes.

Risk of Retinal Neovascularization in Cases of Uveitis

PURPOSE

To evaluate the risk of and risk factors for retinal neovascularization (NV) in cases of uveitis.

DESIGN

Retrospective cohort study.

PARTICIPANTS

Patients with uveitis at 4 US academic ocular inflammation subspecialty practices.

METHODS

Data were ascertained by standardized chart review. Prevalence data analysis used logistic regression. Incidence data analysis used survival analysis with time-updated covariates where appropriate.

MAIN OUTCOME MEASURES

Prevalence and incidence of NV.

RESULTS

Among uveitic eyes of 8931 patients presenting for initial evaluation, 106 of 13,810 eyes had NV (prevalence = 0.77%, 95% confidence interval [CI], 0.60-0.90). Eighty-eight more eyes developed NV over 26,465 eye-years (incidence, 0.33%/eye-year; 95% CI, 0.27-0.41). Factors associated with incident NV include age <35 years compared with >35 years (adjusted hazard ratio [aHR], 2.4; 95% CI, 1.5-3.9), current cigarette smoking (aHR, 1.9; 95% CI, 1.1-3.4), and systemic lupus erythematosus (aHR, 3.5, 95% CI, 1.1-11). Recent diagnosis of uveitis was associated with an increased incidence of NV (compared with patients diagnosed >5 years ago, aHR, 2.4 [95% CI, 1.1-5.0] and aHR, 2.6 [95% CI, 1.2-6.0] for diagnosis within <1 year vs. 1-5 years, respectively). Compared with anterior uveitis, intermediate uveitis (aHR, 3.1; 95% CI, 1.5-6.6), posterior uveitis (aHR, 5.2; 95% CI, 2.5-11), and panuveitis (aHR, 4.3; 95% CI, 2.0-9.3) were associated with a similar degree of increased NV incidence. Active (aHR, 2.1, 95% CI, 1.2-3.7) and slightly active (aHR, 2.4, 95% CI, 1.3-4.4) inflammation were associated with an increased incidence of NV compared with inactive inflammation. Neovascularization incidence also was increased with retinal vascular occlusions (aHR, 10, 95% CI, 3.0-33), retinal vascular sheathing (aHR, 2.6, 95% CI, 1.4-4.9), and exudative retinal detachment (aHR, 4.1, 95% CI, 1.3-13). Diabetes mellitus was associated with a somewhat increased incidence of retinal NV (aHR, 2.3, 95% CI, 1.1-4.9), and systemic hypertension (aHR 1.5, 95% CI, 0.89-2.4) was associated with nonsignificantly increased NV incidence. Results were similar in sensitivity analyses excluding the small minority of patients with diabetes mellitus.

CONCLUSIONS

Retinal NV is a rare complication of uveitis, which occurs more frequently in younger patients, smokers, and those with intermediate/posterior/panuveitis, systemic vasculopathy, retinal vascular disease, or active inflammation. Inflammation and retinal NV likely are linked; additional studies are needed to further elucidate this connection.

Idiopathic Peripapillary Subretinal Neovascular Membrane in a Young Woman with Recurrence of the Lesion during Pregnancy after Treatment with Intravitreal Bevacizumab

We report a 27-year-old woman who was diagnosed with idiopathic peripapillary subretinal neovascular membrane (PSRNVM) in her left eye with best-corrected visual acuity (BCVA) of 20/160. She had been treated by three monthly doses of intravitreal bevacizumab (1.25 mg/0.05 ml) at 4-week intervals, which showed a favorable response. The treatment led to regression of the choroidal neovascular membrane (CNVM) with complete resorption of subretinal fluid and improvement of BCVA to 20/25. Subsequently, recurrence of the CNVM was observed during pregnancy (28 months after treatment). To the best of our knowledge, this is the first report of recurrence of idiopathic PSRNVM during pregnancy.

Peripapillary schisis with serous detachment in advanced glaucoma

PURPOSE

To describe features associated with the development and resolution of peripapillary retinoschisis with an underlying serous detachment in a patient with primary open angle glaucoma. This presentation occurred in the absence of an observed optic nerve coloboma, congenital, or acquired optic nerve head pit.

CASE REPORT

A patient with advanced glaucomatous optic nerve cupping developed a temporally localized peripapillary serous detachment in the right eye which spontaneously resolved.

RESULTS

Optical coherence tomography demonstrated an area of retinoschisis with underlying serous detachment contiguous with the temporal disc margin. Although fluorescein angiography was not performed and the presence of a peripapillary subretinal neovascular membrane could not be ruled out, an atypical coloboma, optic nerve head pit, or peripapillary subretinal neovascular membrane was not observed during biomicroscopy or scanning laser ophthalmoscopy. The retinoschisis and detachment resolved without intervention.

CONCLUSION

Peripapillary retinoschisis with an underlying serous detachment may develop in subjects with advanced glaucoma. Although the occurrence of the findings in this case may be unrelated to glaucomatous optic neuropathy, the likelihood that a pathogenic mechanism linked to advanced glaucoma may be responsible for the development of peripapillary schisis and serous detachment should alternatively be taken into consideration. This case documents its spontaneous resolution without intervention.

Ranibizumab treatment for choroidal neovascularization secondary to causes other than age-related macular degeneration with good baseline visual acuity

PURPOSE

To report a retrospective series of choroidal neovascularization (CNV) patients treated with intravitreal ranibizumab with good baseline vision from causes other than age-related macular degeneration (AMD).

METHODS

We retrospectively reviewed 12 eyes of 12 patients with CNV secondary to non-AMD who received intravitreal ranibizumab injections. Patients with baseline best-corrected visual acuity (BCVA) above 20/63 were included in the study. All patients were followed up at least for 12 months. BCVA measurement, fundus examination, and OCT examination of the patients were performed at each visit. Optical coherence tomography (OCT), fundus photo, fundus autofluorescence, and fundus fluorescein angiography examination of the eyes were obtained. Primary outcome measures were the changing in BCVA and central foveal thickness (CFT). Any ocular or systemic side-effects were recorded.

RESULTS

The ages of patients ranged from 17 to 60. Twelve patients were diagnosed with non-AMD associated CNV: myopia (n = 3), central serous chorioretinopathy (n = 3), idiopathic (n = 2), multifocal choroiditis (n = 2), punctate inner choroidopathy (n = 1), and photo toxicity (n = 1). The improvement in visual acuity was statistically significant (p = 0.001). In the 12-month visit, all eyes had improvement in visual acuity except two eyes. The reduction of the mean CFT was statistically significant (p = 0.001). The CFT of all patients decreased in the 12-month visit. There was no significant difference in comparison of the mean intraocular pressure (p = 0.790). The group received a total of 52 intravitreal injections. The mean number of intravitreal injections was 4.3 (ranged from 3-8).

CONCLUSION

Ranibizumab seems to be an effective and safe treatment option for CNVs secondary to non-AMD causes in patients with relatively good baseline BCVAs.

Management of recurrent inflammatory choroidal neovascular membrane secondary to Vogt-Koyanagi-Harada syndrome, using combined intravitreal injection of bevacizumab and triamcinolone acetate

The purpose of this report is to evaluate the efficacy and safety of combined intravitreal injection of bevacizumab and intravitreal triamcinolone acetonide (IVTA) for recurrent inflammatory choroidal neovascular membrane (CNVM). It was a prospective interventional study of a young female, who was a known case of Vogt-Koyanagi-Harada syndrome. She presented with an inflammatory choroidal neovascualar membrane and signs of panuveitis in the right eye. She underwent a complete ophthalmic examination. She was given intravitreal injection of bevacizumab and IVTA at different sites. There was complete regression of CNVM and ocular inflammation within a week. After six months, she had recurrence of CNVM in the same eye, which was treated similarly. There was a complete resolution of CNVM and ocular inflammation after the combination therapy and systemic steroids, until one year of follow-up. No serious systemic or ocular adverse events were noted. Combination therapy appears to be an effective and safe method in the management of recurrent inflammatory CNVM.

Serpiginous choroiditis and infectious multifocal serpiginoid choroiditis

Serpiginous choroiditis (SC) is a posterior uveitis displaying a geographic pattern of choroiditis, extending from the juxtapapillary choroid and intermittently spreading centrifugally. The choroiditis involves the overlying retinal pigment epithelium, and the outer retina. This intraocular inflammation typically involves both eyes in otherwise healthy, middle-aged individuals with no familial or ethnic predilection. Pathogenesis is unclear; based on limited histopathologic studies, however, favorable response to immunosuppressive agents, and the absence of association with systemic or local infectious or noninfectious diseases, an organ-specific autoimmune inflammation seems likely to be the underlying process. Patients, particularly from tuberculosis-endemic regions, may present with fundus changes simulating SC, but show evidence of active tuberculosis and/or the presence of mycobacterial DNA in the aqueous humor. This has been referred to as serpiginous-like choroiditis, but we prefer the description multifocal serpiginoid choroiditis (MSC). We present the distinguishing features of SC and infectious multifocal serpiginoid choroiditis simulating SC. The distinction is crucial to avoid unnecessarily treating SC with antimicrobial agents. Advances in diagnostic and imaging modalities can help differentiate SC from MSC. Novel local and systemic treatment approaches improve the outcome and preserve vision in SC.

Three-year visual and anatomic results of administrating intravitreal bevacizumab in inflammatory ocular neovascularization

OBJECTIVE

To assess the 3-year visual outcome of intravitreal bevacizumab in inflammatory ocular neovascularization.

DESIGN

Experimental study.

METHODS

Retrospective multicenter consecutive case series in 81 patients with inflammatory ocular neovascularization refractory to standard therapy and treated with intravitreal bevacizumab. The outcome measures included improvement of best corrected visual acuity expressed as logarithm of minimum angle of resolution (logMAR) and paired comparison decrease in central foveal thickness by optical coherence tomography.

RESULTS

Mean best corrected visual acuity improved from baseline 0.699 (6/30 or 20/101) (SD 0.434) to 0.426 (6/16 or 20/53) (SD 0.428) (n = 81; p < 0.001), a gain of 2.7 lines (median 3 injections; 81 eyes; 81 patients). Paired comparisons revealed significant central foveal flattening at 3 years of 97.9 μm (n = 51; p < 0.001). In a subgroup analysis, visual improvement was significant for ocular histoplasmosis (p = 0.026); multifocal choroiditis (p = 0.05); serpiginous choroiditis (p = 0.028); ocular toxoplasmosis (p = 0.042); and punctate inner choroidopathy (p = 0.015). In a subgroup analysis, foveal flattening was significant for ocular histoplasmosis (p = 0.004); multifocal choroiditis (p = 0.007); serpiginous choroiditis (p = 0.011); and punctate inner choroidopathy (p = 0.001). Of the group, 5 eyes developed submacular fibrosis, 1 eye retinal pigment epithelial tear, and 1 eye macular ischemia in the context of vasculitis.

CONCLUSION

At 3 years, intravitreal bevacizumab sustained significant visual improvement of 2.7 lines and significant foveal flattening of 98 μm in a wide variety of inflammatory ocular diseases without major complications after a median of 3 injections.

Five-year visual results of intravitreal bevacizumab in refractory inflammatory ocular neovascularization

Purpose

To assess the 5-year visual outcome of intravitreal bevacizumab in inflammatory ocular neovascularization.

Methods

Retrospective, multicenter, consecutive case series of eight patients with inflammatory ocular neovascularization refractory to standard therapy who were treated with intravitreal bevacizumab and followed for 5 years after first injection. The outcome measures included improvement of best-corrected visual acuity expressed as logarithm of minimum angle of resolution.

Results

Mean best-corrected visual acuity significantly improved from 0.58 at baseline (6/23 or 20/76; standard deviation = 0.32) to 0.20 at final assessment (6/10 or 20/32; standard deviation = 0.25) (n = 8; P = 0.02), a gain of 3.8 lines (median: three injections; eight eyes; eight patients). No ocular or systemic complications from intravitreal bevacizumab were noted.

Conclusion

At 5 years, intravitreal bevacizumab sustained significant visual improvement in ocular neovascularization due to a variety of inflammatory ocular diseases without major complications after a median of three injections.

Management of inflammatory choroidal neovascularization (CNV) secondary to punctate inner choroidopathy in a young female of childbearing age with intra-vitreal ranibizumab and half-fluence photodynamic therapy (PDT) - a holistic approach

Choroidal neovascularization (CNV) may occur in up to 40% of patients with punctate inner choroidopathy (PIC). We report a case of a young woman of childbearing age treated successfully for an inflammatory choroidal neovascular membrane (CNV) secondary to PIC with a combination of intravitreal ranibizumab and photodynamic therapy (PDT).

Visual acuity recovery in a case of idiopathic retinal vasculitis aneurysms and neuroretinitis

PURPOSE

To describe the visual recovery after intravitreal injections of the antivascular endothelial growth factor, bevacizumab, in a case of vaso obliteration from idiopathic retinal vasculitis, aneurysm, and neuroretinitis (IRVAN). The name IRVAN was given to the condition to highlight the key findings present in the disease. IRVAN is a severe, sight threatening condition that can lead to peripheral capillary non-perfusion and vision loss from the ischemic sequelae of vascular occlusion. Panretinal photocoagulation (PRP) is the current standard of care for IRVAN but visual outcome is poor if PRP is initiated after neovascularization develops. Intravitreal bevacizumab has success at treating neovascularization from other ischemic retinopathies and inflammatory retinal conditions that have similar characteristics to IRVAN.

CASE REPORT

This case report describes a patient with decreased vision in the OS. The patient presented with best-corrected visual acuity of 20/20 in the OD and count fingers at 4 ft in the OS. Evaluation revealed findings consistent with an advanced stage of IRVAN. Anterior and posterior neovascularization had developed from extensive capillary non-perfusion in both retinas. A dense vitreous hemorrhage blocked vision OS. Bilateral intravitreal injections of bevacizumab and extensive PRP were given in the area of retinal ischemia for treatment. After 4 months, the patient's vision had improved from count fingers in the OS to 20/40.

CONCLUSIONS

IRVAN has favorable outcomes when treated with a combination of PRP and intravitreal injections of antivascular endothelial growth factor. This case demonstrates the effectiveness of this combination treatment in a case of IRVAN with both posterior and anterior neovascularization.

Ranibizumab therapy for choroidal neovascularization secondary to non-age-related macular degeneration causes

BACKGROUND

To investigate the efficacy of ranibizumab therapy for choroidal neovascular (CNV) membranes secondary to conditions other than macular degeneration.

DESIGN

Prospective case series conducted at the Royal Victorian Eye and Ear Hospital.

PARTICIPANTS

Twelve-month follow-up data for 41 patients with CNV recruited from the outpatient clinic from May 2008 to April 2010 is presented. Fifteen patients had myopia, seven had multifocal choroiditis, and eight had other primary causes.

METHODS

All patients had visual acuity, fluorescein angiogram and optical coherence tomography performed at the initial visit (baseline). Ranibizumab was injected with a standard sterile technique. Patients were reviewed after 1 month, and further injections were given at the treating doctors' discretion.

MAIN OUTCOME MEASURES

Change in visual acuity and central macular thickness at 12 months was compared with baseline for each of the groups. Local and systemic adverse outcomes were recorded.

RESULTS

Analysis was stratified by primary pathology. On average, 40%, 43% and 25% of patients with myopia, multifocal choroiditis and 'other' pathologies, respectively, experienced a three or more line improvement in vision. The average number of injections in 12 months was 4.2 for the entire group. Central macular thickness significantly decreased in the 12-month period for the combined group (P = 0.03). No patient had an adverse systemic side-effect; however, there was one case of endophthalmitis.

CONCLUSIONS

Ranibizumab is an effective treatment for CNV secondary to non-age-related macular degeneration causes, with most patients gaining an improvement in the first 2 months following injection.

Intravitreal bevacizumab as an adjunct to vitrectomy in advanced Eales' disease

Purpose

This study aimed to report the use of intravitreal bevacizumab as an adjunctive treatment in two cases of advanced Eales’ disease with vitreous haemorrhage and tractional retinal detachment, prior to vitreoretinal surgery.

Method

In two patients presenting with vitreous haemorrhage, retinal neovascularisation and localised tractional retinal detachment, 1.25 mg of intravitreal bevacizumab was injected prior to vitrectomy, membrane peeling and endolaser photocoagulation of retina.

Result

Regression of the retinal neovascularisation with resolution of dye leakage on fluoroscein angiography was observed in both cases. Membrane peeling could be performed with minimal bleeding during vitreoretinal surgery in both cases.

Conclusion

Bevacizumab may be a possible adjunctive treatment to vitreoretinal surgery for the management of Eales’ disease with tractional retinal detachment.

Treating peripapillary choroidal neovascular membranes: a review of the evidence

Peripapillary choroidal neovascular membranes (PCNM) are defined as a collection of new choroidal blood vessels, any portion of which lies within one disc diameter of the nerve head. There are two types of PCNM, and correct pre-interventional identification of growth site has been shown to stratify the chance of visual improvement following therapy. Clinical manifestations occur only where the membrane extends over the macula, if the vessels haemorrhage into the subretinal space or fluid exudation occurs within the macula. This review provides an update and overview on the diverse range of current treatment studies and strategies being used in present clinical ophthalmic practice.

Intravitreal bevacizumab as first local treatment for uveitis-related choroidal neovascularization: long-term results

PURPOSE

To report long-term results of intravitreal (IVT) bevacizumab as first local treatment for choroidal neovascularization (CNV) secondary to uveitis.

METHODS

Files of patients receiving 1.25 mg/0.05 ml bevacizumab as primary local treatment for CNV were retrospectively reviewed. Main outcomes were change in best-corrected visual acuity (BCVA) and central foveolar thickness (CFT), treatment-related adverse events, and number and frequency of injections.

RESULTS

Fifteen eyes from fifteen patients were included. Multifocal choroiditis and panuveitis were the diagnosis in seven, ampiginous choroiditis in two, and for six remaining, serpiginous choroiditis, sympathetic ophthalmia, Vogt-Koyanagi-Harada syndrome, punctuate inner choroidopathy, tuberculosis and idiopathic inflammation. In 13 eyes, neovascularization was subfoveal, and peripapillary in two. Intraocular inflammation was strictly controlled in all cases by the time of injections. BCVA improved from logMar 0.53 to logMar 0.29 in 12 eyes (80%), while CFT decreased from 239.06 to 195.2 μm in 13 (87%). Twelve eyes received more than one injection; mean number in this group was 4.25 (2-8), and frequency 1 every 12.97 weeks. There were no adverse events related to bevacizumab or the procedure. Median follow-up was 17.6 months (8-25).

CONCLUSIONS

First-intention IVT bevacizumab for inflammatory CNV showed transient improvement in BCVA and CFT, in eyes under controlled inflammation. Reinjection was needed in most cases. Further work should conclude about safety related to repeated injections.

Positive response to intravitreal ranibizumab in the treatment of choroidal neovascularization secondary to punctate inner choroidopathy

PURPOSE

The purpose of the study was to report the use of ranibizumab in choroidal neovascularization secondary to punctate inner choroidopathy.

METHODS

This was a retrospective case series. Clinical notes of 10 patients with choroidal neovascularization secondary to punctate inner choroidopathy were reviewed (mean age, 40.7 years, age range, 25-58 years).

RESULTS

Previous therapies included photodynamic therapy, posterior sub-Tenon's triamcinolone, oral prednisolone, and intravitreal triamcinolone. Ten eyes in 10 patients underwent a mean of 1.9 ± 1.3 (± standard deviation) injections of antivascular endothelial growth factor (range, 1-5). All 10 patients had a follow-up review of at least 6 months (median, 12.5 ± 9.2 standard deviation; range, 6-34 months). Nine eyes either maintained or improved vision by at least 1 line on the logarithmic of the minimal angle of resolution calculated equivalent chart at least 6 months after the start of treatment with antivascular endothelial growth factor therapy. No ocular or systemic complications were observed.

CONCLUSION

The role of ranibizumab in choroidal neovascularization in association with punctate inner choroidopathy has been shown to be beneficial in this small group in whom improvement or stabilization of vision was observed in 9 of 10 eyes. Recurrent choroidal neovascularization can occur in these patients, and additional injections of ranibizumab appear to be safe and efficacious.
