Optical coherence tomography (OCT) study in Argentinean Huntington's disease patients

Area of Science:

• Neuroscience
• Ophthalmology

Background:

• Huntington's disease (HD) is a progressive neurodegenerative disorder affecting motor and cognitive functions.
• Retinal damage is implicated in other neurodegenerative diseases, but its presence in HD patients requires further investigation.
• Optical coherence tomography (OCT) offers a non-invasive method to assess neurodegeneration by analyzing retinal nerve fiber layers (RNFL).

Purpose of the Study:

• To investigate potential retinal nerve fiber layer (RNFL) thinning in Huntington's disease (HD) patients using optical coherence tomography (OCT).
• To evaluate the utility of OCT as a potential biomarker for neurodegeneration in HD.

Main Methods:

• A cross-sectional study involving 14 Huntington's disease (HD) patients.
• Spectral domain optical coherence tomography (OCT) was performed on all participants.
• Results were compared to a control group, with demographic data also collected.

Main Results:

• Significant thinning was observed in the temporal and superior RNFL sectors of HD patients compared to controls.
• No significant differences were found in the mean total RNFL thickness between HD patients and the control group.
• These findings suggest localized neurodegenerative changes in the retina of HD patients.

Conclusions:

• Optical coherence tomography (OCT) is a rapid, non-invasive technique suitable for assessing retinal changes in Huntington's disease (HD).
• OCT may serve as a valuable biomarker for neurodegeneration in HD.
• Further investigation in larger patient cohorts is warranted to confirm OCT's role in HD.
