The association of aldosterone with papillophlebitis and retinal artery occlusion: A case report

PURPOSE

To explore the association between elevated blood aldosterone levels and papillophlebitis and retinal artery occlusion in a young, healthy woman.

CASE DESCRIPTION

A 19-year-old woman with an unremarkable medical history presented with sudden-onset visual loss in the right eye, which lasted for 10 hours. Fundus examination revealed retinal whitening, splinter hemorrhages, disc swelling, and tortuous vessels in the right eye. Optical coherence tomography revealed inner retinal thickening. Fluorescein angiography demonstrated a delayed arteriovenous transit time and delayed filling of the cilioretinal artery circulation. Further workup showed a high aldosterone level and aldosterone-to-renin ratio. The patient was treated with steroid pulse therapy and combined intravitreal injection of dexamethasone implant and aflibercept. Visual acuity was recovered from count finger at initial presentation to 6/15 on the fifth day. For over 2 months, the fundal manifestations gradually subsided. Three months after the episode, her visual acuity further improved to 6/6.7.

CONCLUSION

This report emphasizes the potential role aldosterone plays in the complex disease mechanism of retinal vasculopathy. In addition, steroid pulse therapy is more effective when applied in conjunction with combined intravitreal injection therapy for rescuing impaired vision caused by retinal vascular occlusion.

Ocular adverse events following intravitreal brolucizumab for neovascular age-related macular degeneration at a single tertiary care center

PURPOSE

To determine the incidence of ocular adverse effects (AEs) following brolucizumab injection for neovascular age-related macular degeneration at a tertiary academic institution.

DESIGN

Retrospective, single center cohort study.

PARTICIPANTS

All patients who received an intravitreal injection of brolucizumab 6 mg for neovascular age-related macular degeneration between October 7, 2019 and July 31, 2020.

METHODS

Medical records of all patients who received brolucizumab 6 mg during the aforementioned time period were carefully reviewed and all ocular adverse effects after injection were charted.

MAIN OUTCOME MEASURES

Incidence of post-injection ocular AEs, including intraocular inflammation (IOI), and time to development of AEs after injection.

RESULTS

A total of 77 patients received brolucizumab 6 mg for a total of 115 administrations during the study period. There were 4 AEs (3.5%), including three cases of IOI (2.6%), one central retinal artery occlusion, and one retinal detachment. Two men and two women were affected.

CONCLUSION

Ocular AEs, including those leading to severe vision loss, may develop after intravitreal brolucizumab 6 mg. A careful discussion of benefits and risks to brolucizumab should be conducted with all patients.

PRECIS

In this first case series of ocular adverse effects after brolucizumab 6 mg injection at a single tertiary care center, the incidence of ocular adverse effects was 3.5%, including a 2.6% incidence of intraocular inflammation.

Closantel retinal toxicity: Recovery from severe vision loss after corticosteroid therapy

PURPOSE

To present a relatively rare case of retinal toxicity and consequent severe vision loss due to Closantel ingestion.

CASE REPORT

A 37-year-old female presented with sudden painless decrease vision in both eyes. She had no previous history of medical disease and denied any trauma. The patient had accidentally ingested Closantel a few days prior to presentation. Closantel is a veterinary anti-helminthic drug used mainly in livestock. Best corrected visual acuity (BCVA) at presentation was 20/200 bilaterally. There was no relative afferent pupillary defect (RAPD) and red saturation test was normal. Macular optical coherence tomography (OCT) revealed disruption in the outer retinal layer and ellipsoid zone in both eyes. A diagnosis of retinal toxicity due to Closantel was made and the patient was started on 1 mg/kg oral prednisolone acetate. On the 45th day after presentation, her BCVA had improved to 20/20 bilaterally.

CONCLUSION

Closantel is a potentially toxic drug causing destruction of the neurosensory retina and visual disturbances. We suggest eye-care personnel awareness regarding the risk of Closantel-induced retinal toxicity and prompt treatment with systemic steroids should be considered.

Visual acuity and progression of macular atrophy in patients receiving intravitreal anti-VEGF for age-related macular degeneration

PURPOSE

Whether intravitreal anti-vascular endothelial growth factors (VEGFs) cause retinal atrophy is still a subject of debate. We reported 13 eyes that received several injections of anti-VEGF for wet age-related macular degeneration (AMD) with good visual acuity despite geographic atrophy on imaging.

METHODS

This is a case series study conducted at Byers Eye Institute at Stanford University. Patients of three retina specialists with wet AMD who received six or more intravitreal injection of anti-VEGFs with visual acuity of 20/60 or better and incomplete RPE and outer retina atrophy (iRORA) or complete RPE and outer retinal atrophy (cRORA) were enrolled in this case series. Different imaging modalities were reviewed by three retina specialists comparing the baseline with the most recent exam.

RESULTS

About 13 eyes of 10 patients met the selection criteria. Eleven eyes were classified as iRORA and 2 as cRORA. Despite the development of macular atrophy on imaging after an average of 38.1 injections, eyes maintained stable visual acuity.

CONCLUSION

The discrepancy between structural and functional findings in this cohort suggests that patients treated by anti-VEGF drugs exhibit divergent clinical outcomes for currently unknown reasons. The authors propose anti-VEGF may affect melanosomes within RPE without disrupting RPE and photoreceptors function completely. This requires further investigation.

Navigated single-capture 3D and cross-sectional wide-field OCT of the mid and peripheral retina and vitreoretinal interface

PURPOSE

Assess the mid and peripheral neuroretina and vitreoretinal interface using a novel Navigated Single-Capture 3D and Cross-Sectional Wide-Field Swept-Source Optical Coherence Tomography (WF SS-OCT) technology with correlation to Multi-Wavelength Ultra-Widefield Imaging (MW UWFI) and Histopathology reference.

METHODS

Retrospective observational study. A total of 74 patients (148 eyes) were imaged using WF SS-OCT and Navigated Single-Capture twelve 23 mm cross-sectional radial scan pattern at 15° intervals. Image diagnosis included: congenital hypertrophy of the retinal pigment epithelium, choroidal nevus, ora serrata pearls, retinal tuft, lattice, snail track, cobblestone degeneration, retinal hole, retinal tear, degenerative retinoschisis, peripheral laser retinopexy, white without pressure, vitreous floaters, subclinical peripheral rhegmatogenous retinal detachment (RD), and tractional RD in proliferative diabetic retinopathy. WF SS-OCT images were correlated with MW UWFI and histopathological references where available.

RESULTS

WF SS-OCT successfully imaged structural features in all diagnoses with significant improvement in diagnostic capability and increased the diagnosis of specific features such as vitreoretinal attachment, full thickness hole or tear and subretinal fluid. Histopathological correlation was available for five (5) different peripheral retinal pathologies imaged by both WF SS-OCT and MW UWFI and good anatomical correlation was observed in all diagnosis.

CONCLUSIONS

Navigated Single-Capture 3D and Cross-Sectional WF SS-OCT provides detailed anatomic information of the mid and peripheral neuroretina and vitreoretinal interface, allowing early recognition of vision-threatening features that may influence clinical management, particularly in an era of telemedicine or when there is limited or no access to Indirect Ophthalmoscopy with 360° Scleral Indentation.

The role of future treatments in the management of neovascular age-related macular degeneration in Europe

Anti-vascular endothelial growth factor (VEGF) agents have transformed the management of patients with neovascular age-related macular degeneration (nAMD) over the past two decades. However, as more long-term real-world data become available, it is clear that treatment outcomes are inferior to those reported in large, controlled clinical trials. This is largely driven by undertreatment, that is, not maintaining a consistent injection frequency to achieve sustained VEGF suppression, whether due to patient non-compliance, an important injection burden, or non/incomplete anatomical response. Newer therapeutic advances under evaluation hold promise in achieving more, for less. We review the latest drugs currently in or having successfully finished phase III clinical trials, and determine their potential place in the management of patients with nAMD in Europe.

Correlation of sectoral choroidal vascularity with angiographic leakage in central serous chorioretinopathy

PURPOSE

To correlate sectoral choroidal vascularity with angiographic leakage in eyes with central serous chorioretinopathy (CSCR).

METHODS

This was a retrospective, cross-sectional study including patients with active CSCR. Multimodal imaging including fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) were performed to identify leakage site and obtain choroidal measurements, respectively. An automated algorithm was used to perform shadow compensation, choroidal boundary localization and binarization, three (3-D) dimensional mapping, and early treatment of diabetic retinopathy study (ETDRS) grid based choroidal quantification that is, choroidal thickness (CT) and choroidal vascularity index (CVI). Nested analysis of variance (ANOVA) was performed to compare CT and CVI in different sectors.

RESULTS

Thirty-two eyes with active CSCR were analyzed. CT values varied significantly among the sectors (range, 450.27-482.63 µm; p = 0.005) and rings (range, 459.71-480.45 µm; p < 0.001), however, CVI failed to show significant variation among various segments (sectors, rings, and quadrants; range, 0.53-0.54; all p values > 0.05). Among 25 leaking spots in 25 different sectors, 12 (48%) had an increased CT compared to the overall CT whereas only 24% had increased CVI compared to overall CVI. Mean CT and CVI of the sectors with leakage (427.1 ± 81.1 µm; 0.51 ± 0.05) and remaining sectors without leakage (411.3 ± 73.9 µm; 0.53 ± 0.04) were not statistically different (p = 0.48; p = 0.12, respectively).

CONCLUSION

Though CT varied in different segments and increased CT corresponded to leakage points on FFA in 48% of eyes, CVI changes were more diffusely spread and local changes in CVI were not predictive of leakage location in eyes with active CSCR.

Dexamethasone implant migration in an eye with congenital glaucoma: A case report and review of the literature

INTRODUCTION

The dexamethasone (DEX) implant is an FDA approved treatment for diabetic macular edema, non-infectious posterior uveitis, and macular edema secondary to branch or central retinal vein occlusions. We describe a case of anterior chamber (AC) migration of a DEX implant in a patient with a history of congenital glaucoma and perform a review of the literature on this particular complication, summarizing the common risk factors, subsequent complications, and management options.

CASE DESCRIPTION

A 46-year-old female with a history of congenital glaucoma, status post cataract extraction with insertion of intraocular lens, pars plana vitrectomy, and Baerveldt tube implant in the left eye was referred for post-operative cystoid macular edema (CME). The patient underwent insertion of a DEX implant, resulting in improvement in her CME. After the fourth implant was injected, the patient noticed a white line in her eye while looking in the mirror after doing jumping jacks. Slit lamp examination confirmed migration of the implant into the AC. Ultimately, the patient was taken to the operating room, where her implant was removed via bimanual vitrectomy through an anterior approach.

CONCLUSION

This case report and literature review explores the ophthalmic structural changes specific to congenital glaucoma which may have predisposed this eye to anterior migration of the DEX implant. The purpose of this review is to detail the anatomic changes that may increase the risk of anterior chamber implant migration in patients with congenital glaucoma so that physicians may be aware of these risks when selecting patients for this implant.

Dexamethasone intravitreal implant in patients with cataract and naïve diabetic macular edema

PURPOSE

To assess the feasibility and clinical effectiveness of dexamethasone intravitreal implant 0.7 mg (IDI) administered in diabetic patients to prevent the worsening of macular edema.

METHODS

Forty eyes of 40 consecutive patients with naïve macular edema secondary to diabetes mellitus who were treated with IDI administered preoperative (Group A: 20 patients) or IDI administered immediately after cataract surgery (Group B: 20 patients). Best-corrected visual acuity (BCVA) and central macular thickness (CMT) changes were evaluated at baseline and at postoperative time points.

RESULTS

Follow-up study was 20 weeks. In Group A and B, mean BCVA improved significantly at all post-surgery time points (p < 0.05). In Group A and B, mean CMT decreased significantly at 16 weeks (p = 0.02 and p = 0.004, respectively). At week 20, CMT failed to reach statistical significance in both groups (p = 0.5, group A and p = 0.15, group B). No statistical differences were noted between groups in term of BCVA (with the exception of week 4 for the presence of cataract in Group A), CMT and IOP.

CONCLUSIONS

The use of intravitreal dexamethasone implant 1 month prior to scheduled cataract extraction or at the time of phacoemulsification appears to be safe and effective for at least 16 weeks after surgery.

Two-year results of a treat and extend regimen with aflibercept in Caucasian patients with aneurysmal type 1 neovascularization

INTRODUCTION

There are a few reports investigating the treatment of aneurysmal type 1 neovascularization (AT1) in Caucasian patients. The aim of this study is to evaluate the 2-year results of a treat and extend regimen with aflibercept in Caucasian patients with AT1.

METHODS

We conducted an observational retrospective study in 28 eyes of 26 patients with naïve AT1 treated with a treat an extend regimen of intravitreal aflibercept. Best corrected visual acuity (BCVA), central macular thickness (CMT), pigment epithelium detachment (PED) height, presence of dry macula, and regression rate of polypoidal lesions were assessed at baseline and at 12 and 24 months.

RESULTS

BCVA was significantly increased by 9.03 ± 16 letters (p < 0.01) and 9.2 ± 16.87 letters (p < 0.01) after the 12 and 24 months follow-up. A significant decrease of CMT was found at 12 and 24 months (p < 0.01). Nevertheless, significant changes in PED height were not observed (0.1 < p > 0.05). At 12 and 24 months of follow-up, dry macula was achieved in a total of 10 eyes (35.71%) and 15 eyes (53.57%). The regression rate of polypoidal lesions was 25% (7 eyes) and 35.71% (10 eyes) after 12 and 24 months. The mean number of intravitreal injections was 7.81 ± 3.20 the first year and 6.11 ± 3.49 the second year.

CONCLUSION

To the best of our knowledge, treat and extend regimen with intravitreal aflibercept in Caucasian patients may be effective for improving BCVA, CMT, wet macula, and regression rate of polypoidal lesions.

Fingolimod-associated macular edema: A case report of late onset

INTRODUCTION

The authors present a case of a male with Multiple Sclerosis (MS) who developed unilateral Fingolimod-Associated Macular Edema (FAME) 10 years after initiating fingolimod therapy. By reporting this case study, the authors present a comprehensive review on FAME, its current incidence, and therapy options in MS patients.

CASE DESCRIPTION

A 58-year-old Caucasian male patient was referred to the hospital with a history of MS. He was on fingolimod treatment for 10 years. The patient presented with a referring second episode of blurred vision in his left eye (OS). His best corrected visual acuity (BCVA) was 20/20 (right eye - OD) and 20/30 (OS). Dilated fundus examination of the OS revealed dull foveal reflex with retinal thickening. Spectral domain optical coherence tomography (SD-OCT) scan demonstrated increased central macular thickness of 459 μm, foveal cysts and subretinal fluid. Neurologists decided to discontinue fingolimod treatment based on the ophthalmological findings. Three months post fingolimod discontinuation, macular edema resolved and BCVA was 20/20 (OD) and 20/25 (OS).

CONCLUSIONS

The authors report a case of late onset FAME. FAME may occur several years after starting fingolimod treatment and it should be part of differential diagnosis of blurred vision in patients receiving fingolimod. Both Microcystic Macular Edema secondary to MS and Macular Edema Associated with MS-induced Uveitis should always be excluded. Those two conditions, secondary to MS, might show the lack of drug effectiveness and the possible need for changing the existing therapy in order to prevent further disease progress.

Efficacy of plasmapheresis as treatment for bilateral hyperviscosity syndrome related retinopathy in multiple myeloma

PURPOSE

To report a case of good clinical response to plasmapheresis as therapy for a bilateral hyperviscosity syndrome related retinopathy in a young patient with undiagnosed multiple myeloma (MM).

METHODS

Case report.

RESULTS

A 48-year-old caucasian man, previously diagnosed with monoclonal gammopathy of undetermined significance (MGUS), presented for medical attention for back ache and vision decrease, worst in the left eye. Ophthalmological examination revealed presence of bilateral CRVO-like retinopathy which raised the hypothesis of hyperviscosity syndrome (HVS). After confirmation of MM diagnosis, plasmapheresis were promptly begun. The right eye regained a good visual acuity and an anatomical restoration already notable 5 days from the first plasmapheresis.

CONCLUSIONS

Fundoscopy lead to diagnosis of HVS, it is therefore advisable in all patients with MM in order to perform plasmapheresis as soon as possible if necessary. In case of atypical CRVO, haematological and inflammatory causes, should be always ruled out.

Multimodal imaging of two cases of retinal vein occlusion secondary to Waldenstrom macroglobulinemia

PURPOSE

To report multimodal imaging characteristics of two cases of retinal vein occlusion (RVO) secondary to Waldenstrom macroglobulinemia (WM).

CASE REPORT

Case 1: An 82-year-old woman presented with vision loss. She had a history of WM. Best-corrected visual acuity (BCVA) was 20/100 Snellen equivalent in the right eye (OD) and 20/63 in the left eye (OS). Fundoscopy showed bilateral hemorrhages in posterior pole and along superotemporal arcade. Fluorescein angiography illustrated no macular leakage. Optical coherence tomography (OCT) revealed macular edema (ME). Optical coherence tomography angiography (OCTA) demonstrated abnormalities in choriocapillaris. A diagnosis of bilateral branch RVO was made and ME was treated with intravitreal dexamethasone, achieving stability. Case 2: A 65-year-old man presented with venous dilation, tortuosity, and intraretinal hemorrhages. BCVA was 20/20 in both eyes (OU). OCT showed ME and hyperreflective dots in choroid. A diagnosis of bilateral central RVO was made. Laboratory evaluation and bone narrow biopsy confirmed a diagnosis of WM. After that, our patient consulted because of vision loss. BCVA was 20/400 in OU. Fundoscopy and OCT demonstrated a worsening of the intraretinal hemorrhages and the ME. OCTA showed damage of choriocapillaris. Thus, intravitreal dexamethasone and plasmapheresis was advised. Two months after, BCVA was 20/40 in the OD and 20/32 in the OS. Also, fundoscopy and OCT improved.

CONCLUSION

Early treatment of WM is truly important, with the aim of achieving a decrease in IgM levels in order to avoid toxic effect over the RPE that results in refractory ME.

Natural course of acquired vitelliform lesions associated with pigment epithelial detachments in dry age related macular degeneration

PURPOSE

To describe the natural history of acquired vitelliform lesions (AVLs) associated with different types of pigment epithelial detachments (PEDs) in dry age-related macular degeneration.

METHODS

A retrospective review of clinical examination and multimodal imaging data of patients with AVLs associated with PED(s) was performed.

RESULTS

This study included 25 eyes of 17 patients. The mean age of patients was 67.2 ± 9.7 (47-83) years. The mean follow-up time was 32.6 ± 16.2 (12-66) months, excluding four patients (five eyes) that were lost to follow-up. The mean logMAR BCVA was 0.21 ± 0.16 at baseline and 0.38 ± 0.28 at final visit (p = 0.016). At the end of the follow-up period, PEDs enlarged in eight eyes (40%) and were unchanged in two eyes (10%). Spontaneous resolution of the central PED(s) with AVLs was seen in four (20%) eyes. Rupture of the PED(s) occurred in four eyes (20%), with two developing central foveolar atrophy afterwards. Overall, central foveolar atrophy was seen ultimately in four eyes (20%).

CONCLUSION

It seems that high PED size may be a risk factor for PED rupture during follow-up. 1/3 of the eyes ended up with unfavorable anatomical outcome.

Multimodal imaging of a vascularized idiopathic epiretinal membrane

PURPOSE

To report a case of vascularized idiopathic epiretinal membrane including the multimodal imaging.

METHODS

Findings on clinical examination, color fundus photography, spectral-domain optical coherence tomography, optical coherence tomography angiography, and fluorescein angiography.

RESULTS

Sixty-three-year-old woman with a previous rhegmatogenous retinal detachment (RRD) who presented with an asymptomatic idiopathic neovascular complex below an epiretinal membrane. It was assessed with fluorescein angiography, OCT and OCT-A. The vascularized ERM was already present previously to the retinal detachment.

CONCLUSION

Our case report describes an example of idiopathic epiretinal membrane complicated by neovascularization; we hypothesized hypertension could be one of the factors in this case, as it may lead to decreased retinal perfusion and upregulation in vascular endothelial growth factor (VEGF). Multimodal imaging can help in detecting neovascularized ERM.

The impact of vision impairment on vision-related quality of life of patients with neovascular age-related macular degeneration

PURPOSE

To investigate the validity and reliability of the Greek Impact of Vision Impairment Questionnaire (IVI) and to explore the predictors of vision-related quality of life (VRQoL) in individuals with neovascular age-related macular degeneration (nAMD).

METHODS

About 191 patients completed the IVI and the SF-12 Health Survey, and were assessed on visual exams. A random group of 20 participants completed the IVI twice with a 2 weeks interval, to assess test-retest reliability. About 102 patients completed the IVI 1 year later in a follow-up examination. Rasch analysis was used to evaluate response category functioning, scale precision, unidimensionality, scale targeting and differential item functioning. Stepwise multiple linear regression analyses identified predictors of VRQoL.

RESULTS

Test-retest reliability of IVI items was calculated from 0.86 to 0.98. The six response categories were merged into four to figure out disordered thresholds. Rasch analysis concluded in three scales: Mobility and Independence, Reading and Accessing Information, and Emotional Wellbeing. Regarding convergent validity, the IVI scores had significant associations with SF-12 components (ρ = 0.28-0.47) and measurements of visual acuity (ρ = 0.39-0.66). Worse VRQoL at 1 year follow-up was correlated with decline in distance and near VA. Distance VA and the SF-12 components were common predictors for all three subscales. The duration of disease was a significant predictor for the emotional subscale.

CONCLUSION

The Greek IVI was found to assess AMD patients' perceptions of VRQoL in a valid, reliable and responsive to eyesight manner. VRQoL was mainly established by patients' distance VA and mental health.

Treat and extend versus fixed regimen in neovascular age related macular degeneration: A systematic review and meta-analysis

PURPOSE

To compare efficacy of treat and extend (T&E) versus fixed regimen treatment protocols in neovascular age-related macular degeneration (nAMD).

METHODS

Randomized clinical trials (RCTs) comparing T&E versus fixed regimen protocols for nAMD were systematically searched. Primary outcome was to compare the mean best corrected visual acuity (BCVA) change in T&E regimen versus fixed regimen. Secondary outcomes were change in the mean optical coherence tomography (OCT) central retinal thickness (CRT) and mean number of injections. Standardized mean difference (SMD) along with 95% confidence intervals (CIs) were calculated. Random-effect models were used for meta-analyses.

RESULTS

Four RCTs were included, with a total of 649 and 621 eyes in the T&E and fixed regimen cohort at 12 months, and 267 and 249 eyes at 24 months. Pooled analysis of mean BCVA change included all four RCTs at 12 months and two RCTs at 24 months, showing no difference between the two groups (12-month: SMD = 0.08, 95% CI: -0.20 to 0.35, p = 0.55; 24-month: SMD = 0.04, 95% CI: -0.13 to 0.21, p = 0.64). Pooled analysis of OCT CRT change at 12 months included three studies, showing no difference between the two groups (SMD = 0.03, 95% CI: -0.46 to 0.51, p = 0.91). Pooled analysis of mean injection number included all four RCTs at 12 months and two RCTs at 24 months, showing significant difference between the two groups (12-month: SMD = -1.11, 95% CI: -1.67 to -0.56, p < 0.001; 24-month: SMD = -1.34, 95% CI: -1.54 to -1.15, p < 0.001).

CONCLUSION

A T&E regimen proved as effective as a fixed dosage regimen throughout a 24-month follow-up and with a lower number of injections.

Intravitreal injections during COVID-19 outbreak: Real-world experience from an Italian tertiary referral center

We report our experience during COVID-19 outbreak for intravitreal injections in patients with maculopathy. We proposed a treatment priority levels and timings; the "High" priority level includes all monocular patients; the "Moderate" is assigned to all patients with an active macular neovascularization; the patients affected by diabetic macular edema or retinal vein occlusion belong to the "Low" class. This organization allowed us to treat the most urgent patients although the injections performed had a 91.7% drop compared to the same period of 2019.

Four-year outcomes of aflibercept treatment for neovascular age-related macular degeneration: Results from real-life setting

BACKGROUND

To assess long-term structural and functional outcomes of intravitreal aflibercept (Eylea^®) treatment for neovascular macular degeneration (nAMD) in a real-word setting.

DESIGN AND METHODS

This was a retrospective, single-centre, non-randomized interventional cohort analysis. Data from treatment-naive patients with nAMD funded for treatment with intravitreal aflibercept in the period between 1 September 2013 and 28 February 2014 and who finished 4-year follow-up entered the analysis. Epidemiological data, visual acuity (VA) measured on ETDRS charts and injection numbers were recorded. Spectral domain optical coherence tomography (SD-OCT) data including presence or absence of macular fluid and automated central subfield macular thickness (CSMT) at year 1, 2, 3 and 4 were also recorded.

RESULTS

Ninety-four eyes of 89 patients finished 4-year follow-up. The mean number of aflibercept injections received over 4 years was 19.3. At baseline, the mean VA (SD) (Snellen) was 54.1 ± 15.5 (20/100) ETDRS letters whilst the mean CSM (SD) was 296 ± 81 µm. At 4 years, the mean VA (SD) (Snellen) was 60.4 ± 20.0 (20/63) ETDRS letters (p < 0.0001). Mean CSMT (SD) was 218 ± 79 μm (p < 0.0001). Thirty-three percent of eyes gained ⩾15 ETDRS letters at end of 4 years, and 66 (70%) eyes had no macular fluid at the end of the follow-up.

CONCLUSION AND RELEVANCE

The results suggest that good long-term morphological and functional treatment outcomes can be achieved using intravitreal aflibercept for nAMD in a real-life clinical setting.
