PARACENTRAL ACUTE MIDDLE MACULOPATHY AFTER COVID-19: MULTIMODAL EVALUATION.

PURPOSE: To report the case and multimodal imaging findings of a healthy young woman who developed paracentral acute middle maculopathy 9 weeks after COVID-19. METHODS: Case report. Ultra-widefield fundus photography, macular spectral domain optical coherence tomography, fluorescein angiography, and optical coherence tomography angiography were performed. RESULTS: A 36-year-old woman went to the emergency department with sudden, painless, left eye vision loss. The only relevant medical history was COVID-19 9 weeks before. The best-corrected visual acuity was 20/200, a left eye relative afferent pupillary defect was present, and superficial hemorrhages throughout the macular area and peripheral retina were found. Nearly 4 hours after admission, the left eye best-corrected visual acuity recovered to 20/20 without relative afferent pupillary defect. Five days after presentation in the emergency department, the patient returned with recurrent left eye vision loss, with spontaneous recovery within 12 hours. Macular spectral domain optical coherence tomography revealed hyperreflectivity of the inner plexiform and inner nuclear layers, and the diagnosis of paracentral acute middle maculopathy was established. The patient started oral acetylsalicylic acid and oral prednisolone. The patient did not report any new episodes of vision loss, and there was a progressive resolution of abnormal fundus findings. CONCLUSION: SARS-CoV-2 infection increases the risk of vascular thrombotic events with possible involvement of the retinal circulation, and paracentral acute middle maculopathy may present as a possible complication. Ophthalmologists should be able to recognize it promptly through multimodal imaging findings.

Bilateral proliferative retinopathy as the initial presentation of chronic myeloid leukemia.

The authors report a rare case of a 48-year-old male with chronic myeloid leukemia (CML) who initially presented with a bilateral proliferative retinopathy. The patient complained of recent visual loss and floaters in both eyes (BE). Ophthalmologic evaluation revealed a best corrected visual acuity (BCVA) of 20/50 in the right eye and 20/200 in the left eye (LE). Fundoscopy showed the presence of bilateral peripheral capillary dropout with multiple retinal sea fan neovascularisations, which were confirmed on fluorescein angiography. Full blood count revealed hyperleukocytosis, thrombocytosis, anemia, and hyperuricemia. Bone marrow aspiration and biopsy showed the reciprocal chromosomal translocation t (9;22), diagnostic of CML. The patient was started on hydroxyurea, allopurinol and imatinib mesylate. He received bilateral panretinal laser photocoagulation and a vitrectomy was performed in the LE. The patient has been in complete hematologic, cytogenetic, and major molecular remission while on imatinib and his BCVA is 20/25 in BE.
