MULTIMODAL IMAGING IN A CASE OF CENTRAL RETINAL ARTERY OCCLUSION IN THE PRESENCE OF TYPE 2 MACULAR TELANGIECTASIA.

PURPOSE: To report a case of central retinal artery occlusion in a patient with macular telangiectasia Type 2 using multimodal imaging. METHODS: Observational case report. RESULTS: A 58-year-old woman who presented with acute painless unilateral vision loss was diagnosed with central retinal artery occlusion in her right eye with macular telangiectasia Type 2 findings in both eyes. Fundus examination revealed retinal whitening with unusual cherry-red spot plus small crystalline deposits in the temporal macula. Surprisingly, spectral domain optical coherence tomography of the contralateral eye showed characteristically intraretinal hyporreflective spaces, whereas optical coherence tomography angiography exhibited microvascular abnormalities in the deep capillary plexus. At follow-up, a pseudolamellar macular hole was noticed in the affected eye with no recovery of best-corrected visual acuity. CONCLUSION: This case describes an onset of central artery occlusion in a patient with underlying macular telangiectasia Type 2 and suggests that it had a possible role in the acceleration of its natural course. The utility of multimodal imaging lies on better accuracy in diagnosis as well as prognosis, management, and monitoring of the disease.

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.

Hemiretinal Artery Occlusion in an 11-Year-Old Child with Dextrocardia.

Purpose. To report a case of hemiretinal artery occlusion in a child with dextrocardia, visceral heterotaxia, and secondary polycythemia. Methods. Complete clinical examination, fundus photography, and retinal fluorescein angiography were performed. Laboratory testing included complete blood cell count, homocysteine, protein c, protein s, activated protein s, methyltetrahydrofolate and homocysteine activator genes, factor leiden V gene, antithrombin III, and activated protein c resistance. In addition, transthoracic and transesophageal echocardiogram and cardiac catheterism were performed. Results. We report an 11-year-old boy with a sudden, painless visual loss in his right eye. His past medical history is remarkable for a congenital cardiac disease. He presented with vision of light perception in the right eye and a relative afferent pupillary defect. Fundus findings included a macular cherry-red spot and inferior hemiretinal whitening consistent with hemiretinal artery occlusion. Laboratory testing showed increased red blood cell (RBC) count, hemoglobin, and hematocrit. The patient was treated with four phlebotomies with improvement of RBC count and after one month reperfusion of the retina and a visual acuity of 20/200 were observed. Thrombophilia and cardiac screening were negative, except for secondary polycythemia. Conclusion. Hemiretinal artery occlusion is extremely rare in children and is often associated with congenital cardiac disease and hypercoagulative states.
