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., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.
