ABSTRACT
We assessed the short-term effects of switching from intravitreal aflibercept (IVA) to intravitreal faricimab (IVF) on ocular blood flow in patients with treatment-resistant diabetic macular edema (DME). The medical records of 15 patients with DME who had received IVA injection ≥ 3 months before were retrospectively reviewed. The best-corrected visual acuity, central macular thickness (CMT) on optical coherence tomography, and mean blur rate (MBR) of all disc areas on laser speckle flowgraphy were measured before, 1 week after, and 4 weeks after IVA and IVF, respectively. The changes in visual acuity showed no significant difference after switching from IVA to IVF (P = 0.732). The mean CMT decreased significantly during the follow-up period (both P < 0.001). MBR showed no significant difference during the follow-up period (P = 0.26). However, it decreased significantly 4 weeks after IVF (P = 0.01) compared with the baseline value, but not 4 weeks after IVA (P = 0.074). A significant association was observed between decreased MBR and decreased CMT in patients who received IVF (correlation coefficient: 0.501, P = 0.005) but not in those who received IVA (P = 0.735). Thus, IVF maintained ocular blood flow reduction, although no significant differences in visual acuity and CMT changes were observed compared to IVA.

RATIONALE: Satoyoshi syndrome is a rare systemic autoimmune disease that presents with painful muscle spasms. We report a case of impending central retinal vein occlusion (CRVO) secondary to granulomatous pan-uveitis in a 32-year-old woman with Satoyoshi syndrome. PATIENT CONCERNS: At the age of 7 years, she developed generalized hair loss and painful spasms and was diagnosed with Satoyoshi syndrome. Her current symptoms included sudden metamorphopsia and decreased visual acuity in the left eye. She visited our hospital with extensive intraretinal hemorrhage (including the macula), meandering of the retinal veins, and swelling of the optic disc. Fluorescence fundus angiography demonstrated hyper fluorescence of the optic disc and leakage from the retinal veins, suggesting CRVO associated with optic papillitis and segmental periphlebitis. DIAGNOSES: In the left eye, there were 2 + cells in the anterior chamber and 1 + in the anterior vitreous. INTERVENTIONS: We increased the existing dose of prednisolone for the treatment of uveitis and started her on oral aspirin and kallidinogenase for CRVO. OUTCOMES: The impending CRVO gradually subsided, and her visual acuity improved. However, during the subsequent treatment course, angle nodules were observed in the left eye, and the intraocular pressure (IOP) gradually increased. Although the angled nodules disappeared with topical corticosteroid treatment, the IOP did not reduce and became uncontrolled. Therefore, we performed trabeculotomy first, followed by trabeculectomy, after which the IOP decreased to approximately 10 mm Hg. LESSONS: Unilateral granulomatous pan-uveitis and impending CRVO were observed in this patient. Several cases of Satoyoshi syndrome complicated by various autoimmune or immunological disorders have been reported. However, to the best of our knowledge, no reports of Satoyoshi syndrome presenting with uveitis or CRVO have been published. Physicians should consider uveitis as a complication of Satoyoshi syndrome.
