Introduction: Vascular endothelial growth factor antibody therapy is an established treatment of exsudative age-related macular degeneration. Aim: The morphologic characterisation of the macular microvasculature after longstanding treatment. Method: Forty-eight patients (34 women and 14 men; age, 74.4 ± 8.0 years) were enrolled in the study. During follow-up time (53.8 ± 31.0 months), 7.6 ± 4.9 injections were administered in 56 eyes. Optical coherence tomography angiographic examination was performed with AngioVue (Optovue Inc. Fremont, CA, USA). Results: Distortion of the superficial retinal plexus and foveal avascular zone enlargement were noted in 5/56 eyes, deep retinal plexus defect was detected in 9/56 cases. Destruction of the choriocapillaries and the former neovascularisation could be found in 4 different patterns: 1. pigment epithelium and choriocapillary atrophy, 2. submacular scar, 3. active leaking choroidal neovascularisation, 4. intraretinal cysts. Conclusion: Optical coherence tomography angiography is a novel non-invasive method, which enables the follow up of macular degeneration. Orv. Hetil., 2016, 157(42), 1683–1690.

Purpose: To observe the relationship between the characteristic changes in the drusen morphology revealed by the spectral-domain optical coherence tomography (SD-OCT) and the progression of age-related macular degeneration (AMD).Methods: A total of 380 drusen in 45 eyes in 35 patients with the intermediate drusen were longitudinally followed up every 6 months by SD-OCT for a period of 24 months. The drusen were divided into the dynamic group and stable group according to the following parameters: number, volume, concurrent retinal pigment epithelium (RPE)/ellipsoid zone (EZ) damage, and the development of advanced AMD. The morphological characteristics of the progressive or stable drusen were further analyzed. Odds ratios (ORs) and the risk for the drusen progression were calculated.Results: The level of interobserver and intraobserver agreement for each drusen tomographic morphological parameters ranged from 82.7 to 90%. At the end of an average follow-up of 15.92 ± 6.99 months, six patients developed choroidal neovascularization and no patients developed geographic atrophy. Finally, 139 drusen changed and 241 drusen remained stable. The drusen with low reflectivity (p < 0.001; OR: 5.26; 95% CI: 2.24–12.36), non-homogeneity without a core (p < 0.001; OR: 4.31; 95% CI: 2.08–8.92), RPE damage (p < 0.001; OR: 28.12; 95% CI: 9.43–83.85), and the EZ damage (p < 0.001; OR: 14.01; 95% CI: 5.28–37.18) were significantly associated with active change; the drusen with low reflectivity (p = 0.01; OR: 2.95; 95% CI: 1.29–6.75) and decreased overlying RPE reflectivity (p < 0.001; OR: 21.67; 95% CI: 9.20–51.02) were the independent predictors for progression. The drusen with high reflectivity were significantly associated with stabilization (p = 0.03; OR: 0.17; 95% CI: 0.04–0.84).Conclusion: Spectral-domain optical coherence tomography is an optimized, accurate, and efficient method to follow-up the drusen. The intermediate non-exudative AMD prognosis of the patient was most strongly correlated with the drusen reflectivity and disruption of the overlying RPE layer. The drusen with low reflectivity and overlying RPE damage were more likely to progress and required frequent follow-up.

Purpose: To identify spectral-domain optical coherence tomography (SD-OCT) features associated with exudative conversion in fellow eyes of patients treated for neovascular age-related macular degeneration (nAMD) in their first eye. Methods: Retrospective observational study. Spectral-domain optical coherence tomography images of converting fellow eyes (study eyes) from 83 patients with nAMD were compared to fellow eyes of age- and sex-matched patients with nAMD who did not convert (control eyes). Parameters related to drusen, pigment epithelium detachment, hyperreflective foci (HRF), retinal pigment epithelium atrophy, small cystic cavities, and vitreoretinal interface were graded. Longitudinal analysis in study eyes and cross-sectional comparison with control eyes at the last 3 semiannual visits before nAMD conversion were performed. Results: For most biomarkers, the prevalence in study eyes increased and imaging findings worsened more than in control eyes. Drusen size and reticular pseudodrusen presence were significantly greater in converting eyes at all 3 time points. Outer retinal small cystic cavities were significantly more common in study eyes shortly before conversion. Binary logistic regression revealed that biggest drusen width was significantly associated with nAMD at all 3 time points (odds ratio [OR] > 1.010; P < .001). The presence of soft drusen was strongly associated with nAMD 18 months before conversion (OR: 7.034; P = .040). Clustering HRF in the inner retina were significantly associated with nAMD both 12 (OR: 1.324; P = .049) and 6 months (OR: 2.161; P = .035) before conversion. Conclusions: Emergence of HRF in fellow eyes, particularly in the inner retina, are sensitive SD-OCT features indicating conversion to exudative disease in patients treated unilaterally for nAMD.

Purpose: To identify best clinical practices for macular degeneration imaging. Methods: We reviewed best clinical practices for imaging patients with age-related macular degeneration. These recommendations are based on different levels of evidence (I-III). Results: The type of imaging needed depends to some degree on the clinical scenario: first visit vs follow-up visit vs poorly responsive patient. Conclusions: Imaging technologies that may be useful include optical coherence tomography, fundus photography, fundus autofluorescence imaging, fluorescein angiography, indocyanine green angiography, and optical coherence tomography angiography.

The authors report a case of a female patient affected by neovascular age-related macular degeneration (AMD). In particular, multiple sub-retinal hyperreflective infiltrates were found on optical coherence tomography. Optical coherence tomography examination of her right eye displayed the presence of sub-retinal pigment epithelium hyporeflective spaces located beneath a hyperreflective fibrotic neovascularization. This case highlights the importance of differentiating choroidal clefts from choroidal caverns.

Introduction: To evaluate the effects of the Navilas system guided by optical coherence tomography angiography for advanced macular neovascularization (MNV) secondary to age-related macular degeneration (AMD). Methods: Prospective case-series including nine eyes presenting with advanced MNV with persistence of exudative signs, no longer responding to anti-VEGF therapy, best-corrected visual acuity at least of 1.3 logMar. All patients were treated with Navilas guided by overlaid optical coherence tomography angiography (OCTA) images at the site of branching large neovascular trunks. Results: Occlusion of large neovascular trunks successfully occurred in all nine included patients. OCTA analysis revealed, at 1 month follow up, MNV total area decreasing from 6.2 ± 3.1 to 2.6 ± 3.4 mm2. At 6 months follow up, mean MNV area was 3.3 ± 3.4 mm2 ( p = 0.008). Conclusion: This preliminary study showed that Navilas treatment guided by OCTA may represent an attractive therapeutic option in advanced neovascular lesions secondary to AMD.
