Optical coherence tomography angiography shows promise for diagnosing and predicting outcomes in neuro-ophthalmology. More research is needed to fully utilize this imaging technique due to limited current data.
Area of Science:
- Ophthalmology
- Neuro-ophthalmology
- Medical Imaging
Background:
- Optical coherence tomography angiography (OCTA) is an emerging imaging technique.
- OCTA offers non-invasive visualization of the ocular vasculature.
Purpose of the Study:
- To review the diagnostic and prognostic potential of OCTA in neuro-ophthalmology.
- To highlight areas for future research in OCTA for neuro-ophthalmic conditions.
Main Methods:
- Literature review of current studies on OCTA in neuro-ophthalmology.
- Analysis of the utility of OCTA for diagnosis and prognostication.
Main Results:
- OCTA demonstrates potential utility in neuro-ophthalmic diagnosis and prognostication.
- Current limitations exist due to insufficient observational data.
Conclusions:
- Further characterization of the optic disc vascular network using OCTA is essential.
- Increased data will enhance the specificity and sensitivity of OCTA in neuro-ophthalmology.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
