Rationale:To report a case of 44-year-old man with delayed suprachoroidal hemorrhage (DSCH) 2 days after cataract surgery.Patient concerns:The patient developed sudden onset of ocular pain and reduction of visual acuity on his left eye 2 days after receiving conventional cataract operation.Diagnoses:The ocular conditions were accessed by best-corrected visual acuity, intraocular pressure, slit lamp examination, fundus photography, and B-scan ultrasound. Fundus color photograph revealed a raised choroidal mass and extensive subretinal hemorrhage. B-scan ultrasound also confirmed features of choroidal hemorrhage. Thus, he was diagnosed as DSCH.Interventions:He received conservative treatments for 1 month.Outcomes:The involved eye recovered well.Lessons:DSCH is a rare but dreaded complication occurring in intraocular operations. Conservative managements or surgeries may be beneficial for the recovery of visual acuity.
