Significant Attention

Recent advances of computerized graphical methods have received significant attention for detection and home monitoring of various visual distortions caused by macular disorders such as macular edema, central serous chorioretinopathy, and age-related macular degeneration. After a brief review of macular disorders and their conventional diagnostic methods, this paper reviews such graphical interface methods including computerized Amsler Grid, Preferential Hyperacuity Perimeter, and Three-dimensional Computer-automated Threshold Amsler Grid. Thereafter, the challenges of these computerized methods for accurate and rapid detection of macular disorders are discussed. The early detection and progress assessment of macular disorders can significantly enhance the required clinical procedure for the diagnosis and treatment of macular disorders.

Disease Study

Purpose: This work evaluated the use and type of dietary supplements and home monitoring for nonneovascular age-related macular degeneration (AMD), as well as the prevalence of genetic testing among patients with AMD. Methods: A cross-sectional study was conducted of 129 participants older than 50 years who completed self-administered questionnaires regarding usage and type of dietary supplements and home monitoring, as well as the participants’ use of genetic testing for AMD. Results: Of 91 participants with AMD, 83 (91.2%) took vitamins, including 55 (60.4%) who used an Age-Related Eye Disease Study (AREDS) or AREDS2 formulation. Of 38 without AMD, 31 (81.6%) took vitamins (difference from participants with AMD = 9.6% [95% CI, 0%-23.2%]), including 2 on an AREDS formulation. Among 82 participants with AMD who were AREDS candidates (intermediate or advanced AMD in 1 or both eyes), 51 (62.2%; 95% CI, 51.7%-72.7%) took an AREDS or AREDS2 formulation, and 31 (37.8%) did not (5 were unsure). Additionally, 50 (61.0%; 95% CI, 50.4%-71.6%) AREDS candidates did some type of home monitoring. Only 1 (1.2%; 95% CI, 0%-3.6%) underwent genetic testing for AMD. Among 9 with AMD who were not AREDS candidates, 4 (44.4%) used an AREDS formulation, 4 (44.4%) did not, and 1 (11.1%) was unsure; only 1 (11.1%) of these 9 performed home monitoring. Conclusions: Despite similar results from past surveys and AREDS2 data supporting supplement use in 2013 and home monitoring in 2014, these findings suggest about one-third of AREDS candidates do not do so, providing further support for improving education regarding appropriate supplement and home monitoring usage. Genetic testing for AMD also appears infrequent.

Poor Outcomes

Introduction COVID-19 has disrupted how ophthalmic practice is conducted worldwide. One patient population that may suffer from poor outcomes during the pandemic are those with age-related macular degeneration (AMD). Many practices are performing some form of teleophthalmology services for their patients, and guidance is needed on how to maintain continuity of care amongst patients with AMD using teleophthalmology. Methods A literature search was conducted, ending 1 August 2020, to identify AMD outcomes and telecare management strategies that could be used during the COVID-19 pandemic Results 237 total articles were retrieved, 56 of which were included for analysis. Four American Academy of Ophthalmology and Center for Disease Control web resources were also included. Discussion Risk-stratification models have been developed that let providers readily screen existing patients for their future risk of neovascular AMD (nAMD). When used with at-home monitoring devices to detect nAMD, providers may be able to determine who should be contacted via teleophthalmology for screening. Telemedicine triage can be used for new complaints of vision loss to determine who should be referred to a retinal specialist for management of suspected nAMD. To increase access and provider flexibility, smartphone fundus photography images sent to a centralized teleophthalmology service can aid in the detection of nAMD. Considerations should also be made for COVID-19 transmission, and teleophthalmology can be used to screen patients for the presence of COVID-19 prior to in-person office visits. Teleophthalmology has additional utility in connecting with nursing home, rural, and socioeconomically disadvantaged patients in the post-pandemic period.

AbstractThis study explored whether rotational three-dimensional (3D) visualization of optical coherence tomography angiography (OCTA) volume data may yield valuable information regarding type 3 macular neovascularization (MNV). In this retrospective, cross-sectional study, we collected data from 15 eyes (13 patients) with treatment-naïve type 3 MNV in their post-nascent stage and age-related macular degeneration (AMD). Subjects were imaged with the SS-OCT system (PLEX Elite 9000, Carl Zeiss Meditec Inc., Dublin, CA, USA). The OCTA volume data were processed with a prototype volume projection removal algorithm and then analyzed using volumetric visualization techniques in order to obtain a 3D visualization of the region occupied by type 3 MNV. The two-dimensional and three-dimensional OCTA images were investigated. Mean ± SD age was 75.1 ± 7.4 years. BCVA was 0.42 ± 0.21 LogMAR in the study eyes. Considering the cohort of analyzed eyes, on rotational 3D OCTA images, a total of 35 neovascular lesions (vs 22 lesions detected on 2D OCTA images) rising from the deep vascular complex and variably spanning the outer retinal layers and eventually reaching the RPE/sub-RPE space were detected. Nine of 35 lesions had a saccular shape, while the remaining cases had a filiform shape. On rotational 3D OCTA images, these lesions were inclined on the three planes, instead of perpendicular to the RPE/Bruch’s membrane. In conclusion, this study used an algorithm to obtain rotational three-dimensional visualization of type 3 MNV. This approach seems to increase the detection rate for these lesions and to be useful to offer new insight into type 3 MNV.
