Pars Plana Vitrectomy, Suprachoroidal Hemorrhage (Diagnosis)
Conditions
Brief summary
To analyze the characteristics, related risk factors, and prognosis of suprachoroidal hemorrhage (SCH) associated with pars plana vitrectomy (PPV).
Interventions
PROCEDURESuprachoroidal hemorrhage associated with pars plana vitrectomy
SCH has a higher incidence rate after a second intraocular surgery in a vitrectomized eye which is associated with the lack of vitreous support and easier fluctuation of intraocular pressure. SCH associated with PPV is more localized and has a relatively good prognosis; high myopia and aphakic/ pseudophakic eyes are risk factors. Active treatment can effectively improve visual prognosis.
