Open Angle Glaucoma: Treatment

Open Angle Glaucoma: Treatment

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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Angle Closure Glaucoma: Treatment

Angle Closure Glaucoma: Treatment

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...

Area of Science:

Ophthalmology
Radiation Oncology

Background:

Central serous chorioretinopathy (CSCR) involves abnormal dilation and hyperpermeability of large choroidal vessels.
Current treatments for refractory CSCR are limited.

Purpose of the Study:

To propose low-dose episcleral brachytherapy as a novel treatment for refractory central serous chorioretinopathy (CSCR).

Main Methods:

Utilizing low-dose radiation delivered via a specialized episcleral brachytherapy device.
The device allows precise dose delivery, with radiation decreasing exponentially with depth.
The proposed method aims to induce intimal proliferation in choroidal vessels and reduce hyperpermeability.

Main Results:

Low-dose radiation can induce intimal proliferation in large choroidal vessels.
The specialized device ensures precise and appropriate radiation dosage.
Increased choroidal thickness in CSCR patients can be accommodated for safe dose delivery.

Conclusions:

Episcleral brachytherapy offers a potential new treatment avenue for refractory CSCR.
Precise dose delivery minimizes risks to the choriocapillaris and retinal vessels.
This technique may effectively manage CSCR by targeting choroidal vascular abnormalities.
