Purpose: This is a retrospective, single-center, non randomized interventional real life study, investigating the correlation between variability of central retinal thickness (CRT) and functional outcomes during 2 years of anti-VEGF therapy in patients treated for neovascular age related macular degeneration (nAMD). Background: CRT fluctuations can depend on various factors such as the correct timing of injections, the therapeutic algorithm, and the number of injections (NI) performed; it is important to understand if CRT fluctuations are responsible for worse visual outcomes and consequently to identify the correct ways to avoid or reduce them. Methods: Forty-one patients were treated for nAMD with aflibercept: 0.5 mg intravitreal aflibercept was administered every 4 weeks during the first 3 months, then bimonthly over the first year, and after the first year adopting a PRN regimen. Standard deviation of CRT (CRT/SD), BCVA, and NI were recorded. Correlation studies were performed by Pearson’s test, Ancova, and Principal Component Analysis. Results: A negative correlation was found between CRT/SD and final BCVA. In patients who lost more than 15 letters, CRT/SD mean was significantly higher in comparison with patients who lost less than 15 letters. Patients with final BCVA >65 letters showed lower CRT/SD values compared to patients with final BCVA ⩽65 letters. Multivariate analysis confirmed that in patients with higher baseline BCVA, improvement of BCVA was correlated to NI, and lower values of CRT fluctuations were observed. Conclusions: CRT fluctuations, even after an appropriate NI given per year, significantly influence BCVA; a proactive treatment algorithm appears crucial when treating patients with nAMD.

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.

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.
