Photopigment bleaching occurs with saturation of photoreceptor pigment by short-wavelength fundus autofluorescence imaging. This phenomenon is seen as characteristic hyperautofluorescence with subsequent imaging acquisition. Herein, a patient with multiple sclerosis was found to exhibit increased choroidal hyperfluorescence during fluorescein angiography (FA) that corresponded with a circumscribed area of intense blue light exposure during initial scanning laser ophthalmoscopy.

Background: There is a need for guidelines on patient navigation activities to promote both the quality of patient navigation and the standards of reimbursement for these services because a lack of reimbursement is a major barrier to the implementation, maintenance, and sustainability of these programs.

Methods: A broad community-based participatory research process was used to identify the needs of patients for navigation. A panel of stakeholders of clinical providers was convened to identify specific activities for navigators to address the needs of patients and providers with the explicit goal of reducing delays in the initiation of cancer treatment and improving adherence to the care plan.

Background: Evidence-based timeliness benchmarks have been established to assess quality of breast cancer care, as delays in treatment are associated with poor clinical outcomes. However, few studies have evaluated how current breast cancer care meets these benchmarks and what factors may delay the timely initiation of treatment.

Patients And Methods: Demographic and disease characteristics of 377 newly diagnosed patients with breast cancer who initiated treatment at Tufts Medical Center (2009-2015) were extracted from electronic medical records.

Purpose: To use swept-source optical coherence tomography and swept-source optical coherence tomography angiography to investigate potential relationships between choroidal vascular hyperpermeability (CVH) seen with indocyanine green angiography (ICGA), choriocapillaris flow density, and choroidal thickness in eyes with pachychoroid pigment epitheliopathy.

Methods: Patients with pachychoroid pigment epitheliopathy were prospectively imaged with 12-mm × 12-mm swept-source optical coherence tomography, 12-mm × 12-mm swept-source optical coherence tomography angiographyA, and ICGA. Binarized choriocapillaris OCTA images were superimposed with ICGA images in which CVH area had been isolated.

Age-related macular degeneration (AMD) is a global health concern and the leading cause of vision loss in the developed world. Intravitreal anti-vascular endothelial growth factor (VEGF) therapy has revolutionized the treatment of neovascular AMD, but there are still challenges with delivery of care and treatment burden with currently available medications. Brolucizumab is a single-chain antibody fragment inhibitor of all isoforms of VEGF-A.

Purpose: To analyze the evolution of type 1 neovascularization associated with vascularized serous pigment epithelial detachment (vsPED) using three-dimensional, volumetric, en face optical coherence tomography angiography (OCTA).

Methods: This was a retrospective case series from four tertiary medical centers. OCTA images were analyzed at baseline and at the 3-, 6-, 12-, 18-, and 24-month follow-up visit when available.

In this Perspective, the authors review Association of American Medical Colleges data on gender parity and intersectionality, consider the literature on gender parity in academic medicine and the underlying gender norms that explain these statistics, and offer recommendations for moving past indicators of parity to achieve gender and social equality.Improvements in gender parity among medical school graduates have not translated to gender parity among practicing physicians or medical school faculty, particularly for racial/ethnic minorities. Further, gender parity does not correspond to gender equality, such that gender-based disparities in salaries and advancement persist.

Purpose: To explore patterns of disease progression in nonneovascular age-related macular degeneration (AMD) associated with hyperreflective crystalline deposits (HCDs) in the sub-retinal pigment epithelium-basal laminar space.

Methods: Retrospective review of medical records, multimodal imaging, and longitudinal eye-tracked near-infrared reflectance (NIR) and optical coherence tomography (OCT) spanning ≥2 years. NIR/OCT images were analyzed with ImageJ software to identify HCD morphology and location.

Central serous chorioretinopathy (CSC) is a common cause of central vision loss, primarily affecting men 20-60 years of age. To date, no consensus has been reached regarding the classification of CSC, and a wide variety of interventions have been proposed, reflecting the controversy associated with treating this disease. The recent publication of appropriately powered randomised controlled trials such as the PLACE trial, as well as large retrospective, non-randomised treatment studies regarding the treatment of CSC suggest the feasibility of a more evidence-based approach when considering treatment options.

Importance: Incidence of conversion to neovascular age-related macular degeneration (nAMD) in untreated fellow eyes of patients who are treated for nAMD in 1 eye with anti-vascular endothelial growth factor agents provides important prognostic information to clinically manage patients.

Objective: To investigate the association of treatment assignment (intravitreal aflibercept vs ranibizumab) and baseline characteristics with fellow eye conversion to nAMD in the VEGF (Vascular Endothelial Growth Factor) Trap-Eye: Investigation of Efficacy and Safety in Wet AMD (VIEW) studies.

Design, Setting, And Participants: This post hoc analysis of the VIEW 1 and VIEW 2 studies (randomized, double-masked, active-controlled, multicenter, 96-week, phase 3 trials comparing the efficacy and safety of intravitreal aflibercept in 2457 patients with treatment-naive eyes with nAMD) analyzed a subgroup of participants treated for nAMD in 1 eye who had untreated fellow eyes without neovascularization at baseline.

Purpose: To analyze "pseudoflow," a false positive flow-artifact observed with optical coherence tomography angiography (OCTA) of stationary hyperreflective structures corresponding to hard exudates and macular drusen.

Methods: Retrospective case series of patients with hard exudates (due to diabetic macular edema [DME] or retinal vein occlusion [RVO]) or macular drusen (due to nonneovascular, or dry, age-related macular degeneration [AMD]) studied with OCTA by using volume-based projection artifact removal (3D PAR).

Results: OCTA of 20 eyes (10 DME/10 RVO) with hard exudates were analyzed.
