Treatment and analysis of risk factors of suprachoroidal hemorrhage induced by intraocular surgery / 中华实验眼科杂志

ABSTRACT

Background Suprachoroidal hemorrhage (SCH)is a rare but devastating complication of ophthalmic surgery,and it is crucial to be aware of the risk factors and select effective treatment. Objective Present study was to assess the treatment and risk factors of SCH induced by intraocular surgery. Methods Retrospective case series were carried out to investigate the clinical data of 15 eyes from 15 patients with SCH at Peking Union Medical College Hospital.The risk factors of SCH were analyzed.Written informed consent was obtained before any medical examination and treatment.SCH was occurred in 10 eyes during intraocular surgery,while the SCH was diagnosed in other 5 eyes 1-3 days after operation.Surgical drainage was carried out in 8 eyes,of which 3 eyes combined with vitrectomy besides surgical drainage and other 5 eyes were treated with medication alone.Results SCH was completely removed and absorbed in 12 eyes.The visual acuity was improved in 6 eyes,unchanged in 6 eyes and decreased in 3 eyes.Nine eyes complicated with retinal detachment and reattached in 6 eyes after treatment.Seven eyes combined with hypermyopia,6 eyes combined with glaucoma,and 1 eye was aphakia.Four patients combined with hypertension,and 2 patients had diabetes mellitus. Conclusions SCH induced by intraocular surgery develops rapidly and violently,and it can result in vision loss without effective treatment.Suturing surgical incision immediately,applying hypertonic agents and sclerotomy drainage are the urgent approaches to treat SCH.Medicines and/or sclerotomy could be optional according to the amount of bleeding and other ocular complication.The risk factors of SCH include myopia,glaucoma and the instantly dropping of intraocular pressure.
