[Pay attention on optical coherence tomography evaluation for optic nerve diseases]

Area of Science:

• Ophthalmology
• Medical Imaging

Background:

• Optical coherence tomography (OCT) is a vital imaging modality in ophthalmology.
• OCT enables precise segmentation and quantitative analysis of retinal nerve fiber and ganglion cell layers.

Purpose of the Study:

• To review the applications of OCT in diagnosing and differentiating optic nerve diseases.
• To highlight key usage points and features of en face OCT and OCT angiography.

Main Methods:

• Review of existing literature on OCT applications in optic nerve diseases.
• Analysis of OCT's capability in segmenting and quantifying retinal layers.
• Discussion of en face OCT and OCT angiography features.

Main Results:

• OCT accurately segments and quantifies retinal nerve fiber and ganglion cell layers.
• OCT is essential for evaluating neuron and axon loss in optic nerve diseases.
• OCT effectively differentiates glaucoma and macular diseases from optic nerve disorders.

Conclusions:

• OCT plays a significant role in the diagnosis and treatment of optic nerve diseases.
• Increased attention to OCT examination is recommended for managing optic nerve conditions.
• En face OCT and OCT angiography offer valuable insights into optic nerve health.
