Role Of Adaptive Optics In Early Diagnosis Of Glaucoma From A Clinician's Perspective

Area of Science:

• Ophthalmology
• Medical Imaging
• Biomedical Engineering

Background:

• Glaucoma is a leading cause of irreversible blindness globally.
• Early detection is critical to prevent visual function loss.
• Current diagnostic tools like OCT and SAP have limitations in diagnosing early glaucoma.

Purpose of the Study:

• To review the application of adaptive optics (AO) technology in ophthalmology for glaucoma diagnosis and monitoring.
• To explore AO's potential to overcome limitations of existing glaucoma diagnostic tools.

Main Methods:

• Literature search of PubMed for publications between 2002-2019.
• Keywords included adaptive optics, lamina cribrosa, retinal nerve fiber layer defects, scanning laser ophthalmoscope, and OCT.
• Review of 17 relevant English-language articles and case series.

Main Results:

• AO, combined with fundus photography, scanning laser ophthalmoscopy, and OCT, allows detailed study of ocular structures in glaucoma patients.
• AO enables imaging of subtle preclinical changes in the retinal nerve fiber layer (RNFL) morphology and reflectivity.
• Longitudinal monitoring of RNFL alterations in glaucoma patients is feasible with AO technology.

Conclusions:

• Adaptive optics technology shows promise for the early detection of glaucoma by imaging subtle RNFL changes.
• AO facilitates detailed monitoring of RNFL alterations over time in glaucoma patients.
• Current limitations of AO include high cost, limited availability, and technical challenges.
