Optical Coherence Tomography and Glaucoma

Area of Science:

• Ophthalmology
• Medical Imaging
• Biomedical Engineering

Background:

• Glaucoma is a progressive optic neuropathy leading to irreversible blindness.
• Early detection and continuous monitoring are vital for managing glaucoma.
• Optical coherence tomography (OCT) is a key imaging tool for assessing structural glaucomatous damage.

Purpose of the Study:

• To review the evolution and current state of OCT technologies for glaucoma.
• To discuss the utility of advanced OCT applications in glaucoma diagnosis and management.
• To explore future directions in OCT for glaucoma evaluation.

Main Methods:

• Review of commercial and state-of-the-art OCT technologies.
• Analysis of analytical techniques used with OCT in glaucoma.
• Discussion of emerging OCT applications like adaptive optics and OCT-angiography.

Main Results:

• OCT technology has advanced significantly since 1991, improving scan resolution and speed.
• Various OCT iterations (TD-OCT, SD-OCT, SS-OCT) enhance glaucoma assessment.
• Newer OCT applications offer richer data for glaucoma evaluation.

Conclusions:

• OCT is indispensable for the early detection and monitoring of glaucoma.
• Continuous technological advancements in OCT are crucial for improved glaucoma management.
• Future OCT developments hold promise for more effective glaucoma diagnosis and treatment.
