Background and objective
To report on details of the choroid in dry age-related macular degeneration imaged with Swept Source Optical Coherence Tomography.
Material and methods
Swept Source Optical Coherence Tomography was performed in 28 eyes with dry age-related macular degeneration (Group 1), who were age and refractive error-matched with 28 eyes of 28 healthy controls (Group 2). The visibility and contour of the outer choroidoscleral boundary and suprachoroidal layer was estimated.
Results
Choroidoscleral boundary was visible in all eyes, irregular in 78% in Group 1 and in 18% in Group 2. Suprachoroidal layer was visible in 36% eyes in Group 1 and in 7% eyes in Group 2. Mean choroidal thickness did not differ between groups (p=.11).
Conclusions
The outer choroidoscleral boundary is irregular in most cases of age-related macular degeneration. Suprachoroidal layer and suprachoroidal space are more often visible in dry age-related macular degeneration than in healthy controls.
