Nine patients with recurrent macular edema secondary to diabetic retinopathy or retinal vein occlusion who could not afford repeated anti-vascular endothelial growth factor treatment received suprachoroidal injection of triamcinolone acetonide using this injector. Changes in SCS, macular edema and visual acuity before and after injection were evaluated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In all patients, anterior-segment optical coherence tomography revealed SCS expansion immediately after injection. At 1 month after injection, spectral-domain optical coherence tomography revealed a reduction in macular edema with average central subfield thickness decreasing from 574.56\u2009\u00b1\u2009151.53 \u03bcm to 338.78\u2009\u00b1\u200961.26 \u03bcm, and best-corrected visual acuity improved from 0.87\u2009\u00b1\u20090.29 logMAR to 0.55\u2009\u00b1\u20090.24 logMAR.
