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...

Confocal Fluorescence Microscopy

Confocal Fluorescence Microscopy

Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

Area of Science:

Ophthalmic optics
Biomedical engineering
Optical instrumentation

Background:

Accurate refractive error measurement is crucial for ophthalmic diagnostics and surgical guidance.
Current methods may lack real-time integration with imaging modalities.
Advancements in optical coherence tomography (OCT) and wavefront aberrometry offer potential for improved ocular measurements.

Purpose of the Study:

To develop and validate a combined anterior segment optical coherence tomography (AS-OCT) and wavefront-based aberrometer system.
To enable simultaneous, real-time measurement of ocular wavefront aberrations and OCT imaging.
To assess the system's accuracy and precision for refractive error assessment.

Main Methods:

Integrated an AS-OCT system with a wavefront-based aberrometer.
Employed temporal interlacing of OCT and aberrometer channels for continuous data acquisition.
Utilized the OCT beam to sense ocular wavefront aberrations.
Validated refractive error measurements against clinical autorefractors.

Main Results:

Achieved continuous, real-time acquisition of OCT images and refractive error measurements.
Demonstrated accuracy and precision comparable to clinical autorefractors.
Developed a compact, modular system design.

Conclusions:

The combined OCT and wavefront aberrometry system offers a novel approach for real-time ocular measurements.
The system's performance is comparable to established clinical autorefractors.
The compact design facilitates integration into ophthalmic surgical microscopes and diagnostic devices for applications like cataract surgery guidance and simultaneous autorefraction/biometry.
