This study compared retinal thickness and visual sensitivity in glaucoma patients. Thicker total retina and ganglion cell complex layers showed stronger correlations with visual function, particularly in the inferotemporal sector.
Area of Science:
- Ophthalmology
- Glaucoma research
- Retinal imaging
Background:
- Glaucoma is a leading cause of irreversible blindness.
- Assessing the structure-function relationship in glaucoma is crucial for early detection and management.
- Circumpapillary retinal thickness and microperimetry sensitivity are key metrics.
Purpose of the Study:
- To compare the relationships between circumpapillary microperimetry (MP)-sensitivity measurements and circumpapillary retinal thickness parameters.
- To investigate these relationships in both healthy eyes and eyes with primary open-angle glaucoma (POAG).
Main Methods:
- Circumpapillary optical coherence tomography (OCT) thickness measurements of the retinal nerve fiber layer (cpRNFL), total retina (cpTR), ganglion cell complex (cpGCC), and outer retina (cpOR) were obtained.
- Circumpapillary microperimetry (MP)-sensitivity measurements were performed in 12 identical sectors.
- The structure-function relationship was analyzed in each sector for healthy and POAG eyes.
Main Results:
- Statistically significant correlations between MP-sensitivity and retinal thickness were found for cpRNFL (5 sectors), cpTR (9 sectors), cpGCC (9 sectors), and cpOR (3 sectors).
- Strong structure-function relationships (r=0.4-0.69) were observed in multiple sectors for cpRNFL, cpTR, and cpGCC.
- Very strong relationships (r>0.7) were found in one sector each for cpRNFL, cpTR, and cpGCC, all located in the inferotemporal sector (sector 5).
Conclusions:
- The circumpapillary structure-function relationship was more extensive for total retinal thickness (cpTR) and ganglion cell complex (cpGCC) thickness compared to retinal nerve fiber layer (cpRNFL) thickness.
- cpTR and cpGCC parameters may warrant greater attention in future glaucoma structure-function research.
- These findings highlight the importance of specific retinal layers in relation to visual function in glaucoma.
