Classification of fundus autofluorescence abnormal patterns in diabetic macular edema

Introduction: Patients with diabetic macular edema can develop fundus autofluorescence alterations; thus far, these alterations have been more widely studied with scanning or confocal laser systems. Objective: To describe and classify fundus autofluorescence abnormal patterns in patients with diabetic macular edema using the fundus autofluorescence system with a flash camera. Method: Observational, retrospective, cross-sectional, descriptive study. Fundus autofluorescence digital images of non-comparative cases with untreated diabetic macular edema, obtained and stored with a flash camera system, were assessed. Inter-observer variability was evaluated. Results: 37 eyes of 20 patients were included. Lens opacity was the most common cause of inadequate image quality. Five different fundus autofluorescence patterns were observed: decreased (13%), normal (40%), single-spot hyper-autofluorescent (17 %), multiple-spot hyper-autofluorescent (22 %) and plaque-like hyper-autofluorescent (8 %). The kappa coefficient was 0.906 (p = 0.000). Conclusions: Different fundus autofluorescence phenotypic patterns are observed with flash camera systems in patients with diabetic macular edema. A more accurate phenotypic classification could help establish prognostic factors for visual loss or for the design of clinical trials for diabetic macular edema.

Azathioprine During the First Trimester of Pregnancy in a Patient with Vogt-Koyanagi-Harada Disease: A Multimodal Imaging Follow-Up Study.

BACKGROUND The aim of this study was to describe the case of a 27-year-old woman who developed Vogt-Koyanagi-Harada (VKH) disease in the 13th week of pregnancy, who was treated with high-dose oral corticosteroids and azathioprine due to its persistent course. CASE REPORT A 27-year-old East Indian woman in her 13th week of pregnancy presented with bilateral decreased visual acuity and metamorphopsia due to bilateral serous retinal detachments and was diagnosed with Vogt-Koyanagi-Harada (VKH) disease. Multimodal imaging, including blue light fundus autofluorescence (FAF), structural spectral domain optical coherence tomography (SD-OCT), en-face OCT, and OCT angiography (OCT-A), was performed at presentation and follow-up, being particularly helpful for identifying recurrences. Her treatment consisted of high-dose corticosteroid therapy, and azathioprine had to be added as an adjuvant due to the aggressive behavior of the disease. She gave birth to a healthy baby at 31 weeks of gestation and remained with 20/20 vision at 8 weeks postpartum. CONCLUSIONS To the best of our knowledge, this is the first report on the use of azathioprine in VKH disease during pregnancy with a successful outcome. Multimodal imaging avoiding the use of fundus fluorescein angiography is key in the diagnosis and follow-up of VKH disease in pregnant women.
