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...

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...

Background:

Fogged surgical fields in endoscopic procedures pose significant risks, including incorrect device use and tissue targeting.
Maintaining clear visualization is crucial for patient safety and surgical outcomes in minimally invasive surgery.

Purpose of the Study:

To develop and evaluate a novel framework for defogging endoscopic video sequences.
To enhance and maintain clear visualization of the surgical field during endoscopic procedures.

Main Methods:

A visibility-driven fusion defogging framework is proposed.
The framework recovers visibility, enhances contrast, and fuses luminance in the gradient domain.
Poisson equation in the frequency domain is used for luminance reconstruction.

Main Results:

The proposed framework effectively removes fog from endoscopic images.
Experimental results on prostate cancer surgery videos show robust defogging performance.
The method outperforms existing techniques in clearing hazy surgical video sequences.

Conclusions:

The developed framework significantly improves visualization in endoscopic surgery by removing fog.
This approach enhances visual quality for medical imaging and high-dynamic range images.
The visibility-driven method offers a robust solution for clearer surgical field visualization.
