Summary
Older age, high preoperative pressure, retinal detachment, aphakia, and scleral buckle increase choroidal hemorrhage risk during vitrectomy surgery. Previous trauma or vitrectomy may reduce risk.
Area of Science:
- Ophthalmology
- Surgical Complications
- Retinal Surgery
Background:
- Choroidal hemorrhage is a rare but serious complication of pars plana vitrectomy.
- Identifying risk factors is crucial for patient selection and surgical planning.
Purpose of the Study:
- To identify and analyze potential risk factors for perioperative choroidal hemorrhage during pars plana vitrectomy.
- To improve patient risk stratification for this surgical complication.
Main Methods:
- Case-control study analyzing 683 vitrectomy procedures.
- 13 cases of choroidal hemorrhage were compared to 50 controls.
- Univariate analysis was used to assess risk factors.
Main Results:
- Incidence of choroidal hemorrhage was 1.9%.
- Significant risk factors included older age, elevated preoperative pressure, rhegmatogenous retinal detachment, aphakia/pseudophakia, and scleral buckle placement.
- Previous ocular trauma and vitrectomy were associated with reduced risk.
Conclusions:
- Several key risk factors for choroidal hemorrhage during vitrectomy have been identified.
- This information can help clinicians identify high-risk patients.
- Good visual outcomes are achievable even after choroidal hemorrhage occurs.
