Age−related macular degeneration is a threatening pathology, gradually leading to a complete loss of central vision, which adversely affects an individual physically and emotionally as well as socially, reducing the life quality of such patients. To analyze the anatomical and functional results of intravitreal injections of aflibercept in the patients with exudative age−related macular degeneration, 47 patients a were prospectively studied. Intravitreal injections of aflibercept were performed by the same surgeon under aseptic operating conditions at a dosage of 2 mg, which was 0.05 ml of the drug. All patients underwent a comprehensive ophthalmic examination, which included visometry, autoceratorefractometry, tonometry, biomicroscopy, and ophthalmoscopy under medical mydriasis, as well as optical coherence tomography. The study took place before the intravitreal administration of aflibercept, one month after each of the three loading injections, 4, 8, and 12 weeks, respectively, after the start of treatment, and 4 weeks after the fourth injection, which was performed 8 weeks after the third loading. The total follow−up period was 24 weeks. For assessing the anatomical and functional efficiency of the treatment the changes in visual acuity, which were adjusted as well as those in the central retinal thickness according to optical coherence tomography were accepted as the criteria. The treatment results showed a significant increase in visual acuity of patients with the most significant increase in the index at week 12 from the beginning of therapy, as well as to a statistically significant decrease in the central retinal thickness within six months of observation. It is obvious that a consistent use of this drug is necessary to achieve stable treatment results. Key words: exudative age−related macular degeneration, visual acuity, central retinal thickness, intravitreal antiangiogenic therapy.

Introduction: Anti-vascular endothelial growth factor therapy has revolutionized the treatment of wet age-related macular degeneration; however, it is important to monitor actual use of ranibizumab and related treatment outcomes in routine practice.Material and Methods: This was a retrospective, observational study to monitor the 2-year outcomes following ranibizumab treatment for wet age-related macular degeneration in Portugal. Patients treated between January 2009 and December 2009 were retrospectively evaluated. All decisions were made by the treating physician in accordance with their usual routine clinical practice. The primary assessment was mean change in visual acuity score using Early Treatment Diabetic Retinopathy Study or Snellen equivalent.Results: A total of 128 patients with wet age-related macular degeneration were analyzed (mean age 79.4 years; mean visual acuity score 54.2 letters). Mean change in visual acuity score from baseline was –1.6 letters (n = 82) at year one and –5.1 letters (n = 72) at year two. The mean number of ranibizumab injections was 3.8 (year one) and 1.6 (year two). On average, patients attended 8.6 and 5.0 visits and optical coherence tomography was used in 75.0% of patients in year one and in 56.3% of patients in year two, respectively.Discussion: Despite a relatively high number of visits, including monitoring visits and use of optical coherence tomography - guided therapy, few injections were administered and visual acuity was not improved.Conclusion: These findings indicate that as-needed treatment resulted in under-dosing in a real-life setting in Portugal. Such limitations may also be related to increasing numbers of patients, resulting in clinic saturation.

Background/objectives: There is a significant variation in the way neovascular age-related macular degeneration patients respond to anti–vascular endothelial growth factor treatment. Both the financial and time cost of treatment are significant. As such, being able to predict patient response to treatment is valuable. Subjects/methods: 72 eyes treated with intravitreal aflibercept were retrospectively included in analysis. For each subject, visual acuity (letters) and central retinal thickness (µm) at baseline, second, third and fourth visits, as well as 12-month visits, were collated; a plot of visual acuity versus time was generated and a slope of the first three (slope3) and first four (slope4) visits was calculated. Differences in visual acuity at each visit compared to baseline were determined, as well as percentage differences in central retinal thickness at each visit compared to baseline. Lesion sub-type and the presence of fluid and haemorrhage were also recorded. Results: The average change in visual acuity over 12 months was +3.2 ± 13.4 letters with 91.2% of patients losing <15 letters. Slope4 was the only significant predictive factor for ‘visual acuity change over 12 months’ ( p < 0.001). Change in central retinal thickness, lesion sub-type, haemorrhage at baseline and the location of fluid at baseline were not useful predictive factors in long-term outcome. Conclusion: Aflibercept is an effective treatment option for neovascular age-related macular degeneration; however, the long-term response should not be predicted until at least three loading dose injections have been given. Visual acuity measures at each visit should be examined, as it is the trend in visual acuity across the first four visits (slope4) rather than the difference in visual acuity between two visits that is the predictive factor.

Importance: To provide new insights into aflibercept effect in non-naive-treated patients with neovascular age-related macular degeneration. Purpose: To assess the efficacy of intravitreal aflibercept in patients with neovascular age-related macular degeneration without optimal response to previous anti-vascular endothelial growth factor A therapy. Design: Single-arm, multi-centre, prospective study. Participants: Patients ⩾50 years with active neovascular age-related macular degeneration, best-corrected visual acuity between 20/32 and 20/320 with suboptimal response to ranibizumab or bevacizumab. Methods: Aflibercept was administered monthly (3-first months), and bimonthly thereafter until month 8. Anatomical and functional outcomes were assessed. Main outcome measure: Percentage of eyes without intra or subretinal fluid on optical coherence tomography after 3-monthly loading doses of aflibercept. Results: A total of 46 patients were included. At week 12, 45.7% (95% confidence interval: 31.5%–60.1%) of eyes showed no fluid on optical coherence tomography. The mean (standard deviation) best-corrected visual acuity increased from 65.1 (8.3) to 69.6 (8.1) letters (+4.5 (5.8) p < 0.0001) and was stabilized at week 40 as compared to baseline. Mean central macular thickness decreased from 430 (119) µm to 323 (100) µm at week 12 (–107 (90) µm, p < 0.0001) and was reduced at week 40 (–46 (111) µm, p = 0.0056). At week 40, 21.7% (95% confidence interval: 9.8%–33.7%) had no fluid. There was a case of presumed noninfectious endophthalmitis that was successfully managed. Conclusion: Almost half of patients presented no fluid on optical coherence tomography at week 12, and there was a clinically significant improvement in best-corrected visual acuity. At week 40, one in five patients did not show intra or subretinal fluid, central macular thickness decreased and best-corrected visual acuity was stabilized compared to baseline.

Purpose/Aim: To examine whether central retinal thickness (CRT) is related to mesopic visual acuity (VA) and low luminance deficit (LLD, difference between photopic and mesopic VA) in eyes with early and intermediate age-related macular degeneration (AMD). Materials and Methods: In a cross-sectional study, 50 pseudophakic subjects older than 63 years were divided into three groups (no AMD, early AMD and intermediate AMD). Spectral domain optical coherence tomography (SD-OCT) was used to measure CRT in the 1 mm-central-area. Best-corrected distance VA was measured under photopic or mesopic luminance conditions and LLD calculated. Subjects were stratified by VA impairment to compare CRTs across these groups. Relationships were examined by stepwise multiple linear regression. Results: No significant differences in mean CRT, photopic and mesopic VA or LLD were detected between the groups no AMD, early AMD and intermediate AMD. However, mean CRTs were 20 microns and 18 microns thicker in the eyes with impaired mesopic VA (> 0.3 logMAR) and impaired LLD (⩾ 0.3 logMAR) compared to the eyes with non-impaired VA or LLD respectively (both p < 0.01). CRT and mesopic pupil size were independent predictors of mesopic VA ( p  = 0.001). CRT emerged as the only independent predictor of LLD ( p  = 0.004). Conclusions: Increased CRT was linked to worse retinal function when measured under mesopic conditions in eyes without AMD and eyes with early to intermediate AMD. SD-OCT imaging combined with VA measurements under low luminance conditions could be a useful tool to detect early AMD.

Purpose To report the bacillary layer detachment on optical coherence tomography in exudative age-related macular degeneration. Methods Retrospective, observational cases Case descriptions Two cases of exudative age-related macular degeneration, one diagnosed as polypoidal choroidal vasculopathy following exudative age-related macular degeneration and other as wet age-related macular degeneration with choroidal neovascular membrane showed separation of myoid and ellipsoid zones of photoreceptor layer on optical coherence tomography. This is termed as BALAD. Other associated features noted were the presence of subretinal hyperreflective material, submacular hemorrhage and subretinal fluid. Both cases were treated with monthly intravitreal injections of Inj. Ranibizumab (0.5 mg/0.05 ml). Following 3 intravitreal injections at monthly intervals, reattachment of the bacillary layer detachment were noted in case 1 while the bacillary layer detachment persisted in case 2. Conclusion Multimodal imaging using optical coherence tomography in these cases revealed the separation of the bacillary layer following exudative age-related macular degeneration; a finding which is not routinely described in literature.

Purpose: To assess intra- and subretinal fluid during the loading phase with intravitreal ranibizumab in exudative age-related macular degeneration and to quantify the accuracy of crosshair scan spectral-domain optical coherence tomography with regard to retinal fluid. Methods: This is a retrospective study of 31 treatment-naive patients who received 3 monthly intravitreal ranibizumab injections. Visual acuity and the presence of retinal fluid were assessed at each visit using volume and crosshair scan protocols. Results: Visual acuity improved and central retinal thickness decreased significantly during the loading phase. However, retinal fluid persisted in two thirds of the patients. The accuracy of the crosshair scan to detect fluid was 93%. Conclusions: A substantial proportion of eyes had persistent fluid after 3 months of ranibizumab injections. However, visual improvement was independent of residual fluid. Message: Crosshair scans detect relevant collections of retinal fluid accurately and may be sufficient in daily clinical practice.

Purpose Visual outcome in patients with neovascular age-related macular degeneration is variable. We aimed to evaluate for association between socioeconomic status visual acuity in neovascular age-related macular degeneration. Methods A retrospective single-center study of a consecutive group of neovascular age-related macular degeneration patients was performed. Socioeconomic status was determined for each patient based on the 2008 Israeli census. Medical information was extracted from medical records and included visual acuity and optical coherence tomography parameters. Associations between socioeconomic status and clinical outcomes were analyzed. Results A total of 233 patients were included in the analysis. A correlation was found between low baseline visual acuity of the first eye diagnosed with neovascular age-related macular degeneration and low socioeconomic status (r = −0.13, p = 0.049; n = 233). The difference between the visual acuity of the lowest and the highest socioeconomic status categories at baseline was approximately 3 ETDRS lines (p = 0.048). Socioeconomic status and baseline visual acuity of the second eye of the same individual with neovascular age-related macular degeneration were not correlated (r = −0.05, p = 0.95). Socioeconomic status was not associated with the number of anti-vascular endothelial growth factor injections of the first or second eye, or the visual acuity outcome of the first or second eye after 1 year of therapy (p = 0.421, p = 0.9, respectively). Central subfield thickness of the first eye at presentation as measured by spectral-domain optical coherence tomography was associated with socioeconomic status (r = −0.31 p = 0.001). Conclusion Individuals of lower socioeconomic status presented at more advanced stage of the disease when developing neovascular age-related macular degeneration in the first eye but not in the second eye. The research underscores the importance of improving referral patterns and awareness for the lowest socioeconomic status classes.
