Abstract Purpose:We examined suprachoroidal hemorrhage(SCH) during intraocular surgery at our hospital.

Subjects and methods:Cases of SCH occurring at Miyata Eye Hospital from January 2000 to December 2023 were included. We assessed age, gender, past medical history, surgical method, anesthesia method, incidence of SCH, time to onset of SCH, intraocular of intraocular pressure, corrected visual acuity(preoperative and 1 year postoperative), and treatment.

Results:Patients ranged in age from 54 to 83 years, with a mean age of 70.9±9.5 years, 4 males and 7 females. Ophthalmologic history included glaucoma in 6 cases, long axial lens length in 2 cases, history of ocular trauma in 2 case, uveitis in 1 case, and aphakia in 1 case. The causative surgeries were cataract surgery in 4 cases, vitreous surgery in 5 cases, and total corneal transplantation in 2 cases. The onset of SCH was intraoperative in 9 cases and postoperative in 2 cases, with postoperative cases occurring within 24 hours. The severity of SCH was Grade Ⅰ in 3 cases, Ⅱ in 2 cases, Ⅲ in 2 cases, and Ⅳ in 4 cases(Wang et al. classification). One-year postoperative corrected visual acuity greater than 0.3 was seen only in Grade Ⅰ, with better visual acuity than in Grades Ⅱ to Ⅳ.

Conclusion:Intraoperative intraocular pressure fluctuations were considered the main cause of extrafoveal choroidal hemorrhage in intraocular surgery. Visual prognosis was good in Grade Ⅰ cases and was related to the severity of the disease.
