Summary
Severe plasminogen activator inhibitor-1 (PAI-1) deficiency is linked to spontaneous subhyaloidal hemorrhage. This case highlights the importance of considering PAI-1 deficiency in young patients with unexplained eye hemorrhages.
Area of Science:
- Ophthalmology
- Hematology
- Genetics
Background:
- Spontaneous subhyaloidal hemorrhage is a rare condition.
- Plasminogen activator inhibitor-1 (PAI-1) deficiency is a rare bleeding disorder characterized by hyperfibrinolysis.
Observation:
- A 29-year-old woman presented with sudden, painless vision loss.
- Ophthalmoscopy revealed a massive subhyaloidal hemorrhage in her right eye.
- No typical risk factors for hemorrhage were identified.
Findings:
- Further investigation revealed severe PAI-1 deficiency causing hyperfibrinolysis.
- The subhyaloidal hemorrhage was successfully treated with pars plana vitrectomy.
- Visual acuity improved to 20/20 post-treatment.
Implications:
- Severe PAI-1 deficiency should be considered in the differential diagnosis of spontaneous subhyaloidal hemorrhage.
- Screening for hyperfibrinolysis may be beneficial in young patients with unexplained subhyaloidal hemorrhages.
- This association underscores the systemic impact of PAI-1 deficiency.
