RESUMEN
PURPOSE: Report the clinical and imaging findings of a patient with an intraretinal benign tumor that was documented as an unexpected clinical finding after an ischemic stroke in the context of mitral valve disease. This tumor must be distinguished from retinoblastoma and other malignant neoplasms. METHODS: A patient with intraretinal tumor of the inner nuclear layer (INL) underwent a combination of ophthalmic examination, fundus photography, fluorescein angiography, optical coherence tomography (OCT), and optical coherence tomography angiography (OCT-A). RESULTS: A 64-year-old male patient with unilateral benign tumor lesions dependent on the internal retina, centered in the posterior pole, and multifocal. OCT showed that these lesions were centered within the INL at the edge of the inner plexiform layer and were not associated with other findings in the posterior pole. CONCLUSIONS: Benign Lobular Inner Nuclear Layer Proliferations (BLIP) of the Retina are recently described lesions that should be considered, given their distinctive characteristics that set them apart from other benign and malignant retinal lesions.
RESUMEN
PURPOSE: To describe a rare presentation of pachychoroid neovascular membrane in a patient with sickle cell trait and the accuracy of ruling out hemoglobinopathies in the presentation of pachychoroid spectrum. METHODS: The patient was subjected to physical examinations, multimodal images (fluorescein angiography, optical coherence tomography), hemoglobin electrophoresis, and peripheral blood smear, documenting sickle cell trait. The management included laser treatment to target non-perfusion areas, along with a single dose of anti-VEGF. RESULTS: A 45-year-old male patient with diagnosis of pachychoroid neovascularization treated for 6 years with multiple anti VEGF injections in the left eye. A detailed clinical evaluation included hypochromic conjunctiva, peripheral vascular occlusion with non-perfusion areas led us to suspect sickle cell disease retinopathy. The images of fluorescein angiography showed peripheral arteriovenous anastomosis with non-perfusion areas; the optical coherence tomography revealed a thinner neuroepithelium with a thicker choroid; also, hemoglobin electrophoresis and peripheral blood smear documenting sickle cell trait. The chosen management was photocoagulation of the peripheral retina on the non-perfusion areas and anti VEGF without neovascular activity recurrence in the follow up period. CONCLUSION: Although sickle cell trait is considered a mild form of this pathology without serious retinal manifestations, it has to be noted that in the context of pachychoroid spectrum diseases is a trigger that could perpetuate retinal ischemia and neovascular activity.
