This system would overcome these pandemic and post-pandemic issues by personalizing the visits such that those who maintain anatomic stability may need to come in only when fluid reaccumulates, while those who need frequent injections based on OCT imaging will know that it is necessary to come in for injections. It is, therefore, incumbent upon the treating retina physician community to find alternative ways to deliver high-quality care to ensure that patients do not lose vision while minimizing office visits.Īn OCT home monitoring system that is able to detect the anatomic changes characteristic of nAMD would have the potential to reduce VA loss, the burden to patients, caregivers and clinics, and the costs of care related to nAMD. This may hold especially true in the wake of COVID-19, as the typical AMD patient is at a higher risk for developing complications from the viral infection and may be more apprehensive about coming to the clinics for evaluation and treatments.

For some elderly patients, continual frequent visits to clinics are advisable, since improved vision associated with anti-VEGF treatment may provide quality of life and economic value to patients and society however, this imposes significant burden on patients of transportation or caregiver availability, as well as the frequency of treatment that may lead to treatment fatigue and eventual discontinuation of treatment. Therefore, the patients must be seen in the clinic to undergo an OCT imaging to help the physicians to determine if the disease has progressed and warrants treatment and to determine the proper interval for the next visit.

Spectral domain OCT (SD-OCT) is currently most commonly used and has excellent capabilities to image intraretinal, subretinal, and subretinal pigment epithelial fluid, the main manifestations of nAMD that drive treatment and treatment interval decisions.Ĭurrently OCT machines are available only in the clinics. In addition to visual acuity (VA) and clinical findings based on fundus examinations, the assessment of the macula and the decision to treat or not are mainly driven by interpretation of retinal scans from optical coherence tomography (OCT) systems performed in the office during the patient visit.

Several treatment regimens exist for the management of eyes with nAMD using intravitreal anti-vascular endothelial growth factor (VEGF) injections, including injections performed monthly, treat-and-extend and pro re nata (PRN). While neovascular AMD (nAMD) represents only 10–15% of all AMD, it is responsible for more than 80% of all AMD-related vision loss. Most vision loss associated with age-related macular degeneration (AMD) is caused by atrophy or neovascularization with exudative changes occurring at the macula. Self-testing with the NVHO can produce high quality images suitable for fluid identification by human graders, suggesting the device may be able to complement standard-of-care clinical assessments and treatments. Positive percent agreement/negative percent agreement for detecting the presence of subretinal and/or intraretinal fluid when reviewing for fluid in three repeated volume scans were 97%/95%, respectively for the NVHO v3. Higher rates of successful imaging were found in eyes with VA ≥ 20/320. In the NVHO 3 cohort, 69 eyes of 45 subjects (93%) completed the self-imaging. Successful images were acquired with the NVHO 2.5 in 469/531 eyes (88%) in 264/290 subjects (91%) with the mean (SD) age of 78.8 (8.8) 153 (58%) were female with median visual acuity (VA) of 20/40. Outcomes included patients’ ability to acquire analyzable OCT images with the NVHO and to compare those with commercial images. Prospective, cross-sectional study where patients underwent commercial OCT imaging followed by self-imaging with either the NVHO 2.5 or the NVHO 3 in clinic setting. To compare identification rates of retinal fluid of the Notal Vision Home Optical Coherence Tomography (OCT) device (NVHO) when used by people with age-related macular degeneration (AMD) to those captured by a commercial OCT.
