Resumo:
Background.Studies demonstrate the need for long-term follow-up of patients with wet age-related macular degeneration (AMD) treated with inhibitors of angiogenesis to monitor long-term vision outcomes and assess the safety of antiangiogenic therapy in relation to the risk of secondary geographic atrophy. Aims to determine the characteristic clinical and functional signs of secondary GA that developed against the background of wet AMD. Methods.In 22 patients (25 eyes) with wet AMD and 18 healthy subjects comparable in age and sex standard ophthalmological and instrumental studies were performed and photopic electroretinograms (ERGs) were recorded according to ISCEV standards, flicker-ERGs, multifocal ERGs and electrooculogram. Results.The appearance of the area of secondary atrophy against the background of wet AMD in eyes treated with inhibitors of angiogenesis is clinically indistinguishable from areas of geographic atrophy that developed as an outcome of dry AMD. The ERG-signs of secondary atrophy are described, which are similar to the biomarkers of primary atrophy and specifically differ from them. Secondary atrophy is characterized by the dependence of the increase in the b/a ratio on the atrophic area, reducing of the 8.3 Hz-flicker-ERG amplitude in the absence of 24 Hz-flicker ERG changes. In eyes with secondary atrophy, a significant decrease in the density of the multifocal ERG P1-peak was shown not only in the first hexagon but also in the parafoveal zone. The electrooculography results showed a sharper dark troughs decrease in with an increase in Ardens ratio in patients with secondary atrophya on the background of wet AMD, in contrast to the previously described changes in primary geographic atrophy. Conclusion.Comparison of the change in the b/a ratio with secondary atrophy area in patients with wet AMD may have clinical implications for assessing retinal dysfunction and predicting visual function. Secondary atrophy is associated with a pronounced inhibition of photoreceptor activity with better preservation of cone bipolar cells. The ERG and electrooculography data taking together indicate a more significant dysfunction of the retinal pigment epithelium in GA against the background of wet AMD and the associated deterioration of photoreceptor function than the changes characterizing primary geographic atrophy.

Background/aimsTo identify ocular phenotypes in patients with geographic atrophy secondary to age-related macular degeneration (GA) using a data-driven cluster analysis.MethodsThis was a retrospective analysis of data from a prospective, natural history study of patients with GA who were followed for ≥6 months. Cluster analysis was used to identify subgroups within the population based on the presence of several phenotypic features: soft drusen, reticular pseudodrusen (RPD), primary foveal atrophy, increased fundus autofluorescence (FAF), greyish FAF appearance and subfoveal choroidal thickness (SFCT). A comparison of features between the subgroups was conducted, and a qualitative description of the new phenotypes was proposed. The atrophy growth rate between phenotypes was then compared.ResultsData were analysed from 77 eyes of 77 patients with GA. Cluster analysis identified three groups: phenotype 1 was characterised by high soft drusen load, foveal atrophy and slow growth; phenotype 3 showed high RPD load, extrafoveal and greyish FAF appearance and thin SFCT; the characteristics of phenotype 2 were midway between phenotypes 1 and 3. Phenotypes differed in all measured features (p≤0.013), with decreases in the presence of soft drusen, foveal atrophy and SFCT seen from phenotypes 1 to 3 and corresponding increases in high RPD load, high FAF and greyish FAF appearance. Atrophy growth rate differed between phenotypes 1, 2 and 3 (0.63, 1.91 and 1.73 mm2/year, respectively, p=0.0005).ConclusionCluster analysis identified three distinct phenotypes in GA. One of them showed a particularly slow growth pattern.

Resumo:
Geographic atrophy (GA) secondary to age-related macular degeneration is the leading cause of permanent vision loss in patients over the age of 50 in developed countries. GA is characterized by the atrophy of retinal pigment epithelium and photoreceptors and can lead to central or peripheral vision loss, depending on the location of the atrophy. Currently, there are no US Food and Drug Administration-approved treatments for GA. Avacincaptad pegol (Zimura®; IVERIC Bio Inc, New York, NY, USA) is a C5-specific inhibitor that is being investigated as a potential treatment for GA. C5 is a key protein within the complement system, which maintains retina integrity and health under normal conditions. It is hypothesized that unregulated activation of the complement system (indicated by elevated levels of active proteins such as the membrane attack complex) can exacerbate the progression of GA. This article reviews the latest data regarding avacincaptad pegol as an investigational therapeutic for GA.

Purpose. To evaluate compass (CMP), a recently introduced device that combines scanning ophthalmoscopy, automated perimetry, and eye tracking, for fundus-guided perimetry (microperimetry) with the purpose of correlating perimetric retinal sensitivity (PRS) and retinal geographic atrophy (GA) features. Materials and Methods. A retrospective, cross-sectional study was performed in 56 eyes of 43 patients affected by GA. All patients underwent compass 10-2 perimetry, consisting of a full-threshold visual field on fundus photography and an infrared (IR) image of the central 30° of the retina. Data were exported to an Excel sheet. Binarization with black/white (B/W) variables was applied on the compass photo fundus and matched with visual field scores. Patients underwent autofluorescence (AF) and IR images (Heidelberg, Germany): CMP and Heidelberg IR images were homologated by using GIMP software (https://www.gimp.org), and then atrophic areas were manually measured with the ImageJ program. CMP perimetric grid was overlapped with AF and IR pictures by using GIMP, obtaining composite TIFF images, which were then analyzed with the ImageJ greyscale score (GSS) tool. A hyperautofluorescent halo was identified on the GA edges of some patients. Pearson’s correlation between GA size on IR compass and IR Heidelberg and between GSS and PRS values has been calculated; the independent t-test was realized to calculate the correlation between GSS and B/W variables identified on the CMP photo fundus. The Spearman correlation between total deviation and pattern deviation was calculated. Results. The AUC-ROC score between CMP scores and B/W variables was 93,4%. The Spearman correlation between total deviation and pattern deviation was highly significant ( p = 0,00 ). The correlation between AF GSS values and PRS was significant ( p value = 0,00), the correlation between GSS of hyperautofluorescent points and PRS was significant ( p value = 0,00), and the correlation between IR GSS and PRS was significant ( p value = 0,00). The correlation between AF GSS and B/W variables was significant ( p value = 0,002), the correlation between hyperautofluorescent points and B/W was not significant ( p value = 0,40), and the correlation between IR GSS and B/W was significant ( p = 0,00 ). Conclusions. Based on our preliminary results, compass seems to be a reliable, quick, and safe device for the anatomical and functional study of GA. The direct visualization of the visual field on the fundus photography as a background allows a precise assessment and clinical monitoring of this disease.

AimsTo evaluate the choriocapillaris (CC) flow alterations around geographic atrophy (GA) in eyes with dry age-related macular degeneration.MethodsUsing a swept-source optical coherence tomography angiography (SS-OCTA) device, two volume 6×6 mm scans were acquired in patients with GA presenting between June and December 2017 at the Doheny-UCLA Eye Centers. The area of GA was delineated on the en face structural OCT fundus images. For each eye, the en face OCTA slabs at the level of the CC from the two acquisitions were averaged and compensated for signal loss using the corresponding structural en face images. The resulting images were binarised and analysed for the percentage of flow voids in the para-atrophy zone (a 500 µm wide ring around the immediate edge of the atrophy) and in the peri-atrophy zone (a 500 µm wide ring around the para-atrophy zone edge), the latter considered as a reference in the comparative analysis.ResultsThirty eyes of 20 patients were enrolled. The percentage of flow voids in the para-atrophy zone was 27.23%±6.29% and was significantly higher than in the surrounding peri-atrophy zone (23.4%±6.01%; p<0.001). There was no significant correlation between the flow void percentage in these regions and age, visual acuity, extent of the atrophic area or central choroidal thickness.ConclusionsA significant impairment of the CC flow is present in the zone immediately surrounding the GA lesions strengthening the hypothesis that CC alterations may be relevant to the progression of GA.

Resumo:
AbstractThe pathophysiology of dry age-related macular degeneration (AMD) and specifically geographic atrophy (GA) has been linked to the complement cascade. This cascade is part of the innate immune system and is made up of the classical, alternative, and lectin pathways. The pathways comprise a system of plasma and membrane-associated serum proteins that are activated with identification of a nonself entity. A number of these proteins have been implicated in the development and progression of dry AMD. The three pathways converge at C3 and cascade down through C5, making both of these proteins viable targets for the treatment of dry AMD. In addition, there are a number of complement factors, CFB, CFD, CFH, and CFI, which are potential therapeutic targets as well. Several different complement-directed therapeutics are being studied for the treatment of dry AMD with the hope that one of these approaches will emerge as the first approved treatment for GA.
