Summary
Orbital decompression surgery improved choroidal perfusion in patients with Graves' ophthalmopathy. This treatment enhanced visual acuity and reduced intraocular pressure, resolving pre-operative perfusion defects.
Area of Science:
- Ophthalmology
- Endocrinology
Background:
- Graves' ophthalmopathy can cause optic nerve compromise.
- Choroidal perfusion abnormalities may occur in Graves' orbitopathy.
Purpose of the Study:
- To evaluate choroidal blood flow changes after orbital decompression surgery.
- To assess the impact of surgery on visual function and intraocular pressure.
Main Methods:
- Interventional case series involving three patients with Graves' disease.
- Ophthalmic examinations and high-speed indocyanine green angiography were performed pre- and post-surgery.
Main Results:
- Pre-operative choroidal perfusion defects were observed in affected eyes.
- One year post-surgery, these defects improved or resolved.
- Patients experienced improved visual acuity, color vision, and decreased intraocular pressure.
Conclusions:
- Orbital decompression surgery can positively impact choroidal circulation in Graves' orbitopathy.
- The procedure may improve visual outcomes and reduce intraocular pressure.

01:25Glaucoma: Overview
1.5K
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...

01:27Open Angle Glaucoma: Treatment
1.1K
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:28Angle Closure Glaucoma: Treatment
1.4K
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...
