Summary
Suprachoroidal hemorrhage (SCH) after pars plana vitrectomy (PPV) is rare but linked to factors like prior surgeries. Prompt treatment improves visual outcomes, especially in high myopia and aphakic eyes.
Area of Science:
- Ophthalmology
- Surgical Complications
- Retinal Surgery
Background:
- Suprachoroidal hemorrhage (SCH) is a known complication of ocular surgery.
- Pars plana vitrectomy (PPV) is a common surgical procedure for various retinal conditions.
- Understanding SCH associated with PPV is crucial for improving patient outcomes.
Purpose of the Study:
- To investigate the characteristics of suprachoroidal hemorrhage (SCH) following pars plana vitrectomy (PPV).
- To identify risk factors associated with SCH after PPV.
- To analyze the prognosis and effective treatments for SCH in patients undergoing PPV.
Main Methods:
- Retrospective analysis of 28 SCH cases associated with PPV (excluding trauma) from 2010-2020.
- Data collection included patient demographics, ocular characteristics, SCH onset, treatment, and visual prognosis.
- Patients were categorized by PPV sequence and SCH onset time (expulsive vs. delayed).
Main Results:
- The incidence of SCH after PPV was 0.06%, with 21 cases involving high myopia and 25 aphakic/pseudophakic.
- SCH after a second intraocular surgery in a vitrectomized eye occurred more frequently in younger patients.
- Good visual prognosis was correlated with baseline vision; active treatment positively impacted outcomes.
Conclusions:
- SCH incidence is higher after repeat intraocular surgery due to lack of vitreous support and IOP fluctuations.
- High myopia and aphakia/pseudophakia are identified risk factors for SCH post-PPV.
- Localized SCH associated with PPV generally has a good prognosis, especially with active intervention.

01:25Glaucoma: Overview
1000
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
