To present a new parameter to study the fovea and to quantify foveal pit contour (FPC) changes that occur with aging in normal eyes
Clinical Eye Unit and paediatric Ophthalmology Service, Heliodor Swiecicki University Hospital, Poznan University of Medical Sciences, Poznan, Poland
Spectral domain optical coherence tomography (Avanti RTvue, Optovue Inc., Fremont, USA) foveal scans of patients with no ocular pathology were included in the study. Each scan was analyzed to determine points with the highest retinal thickness located nasally and temporally to the foveal pit. Area of FPC was calculated for each patient with our software for OCT data investigation.
There were 169 eyes included in the study. We were able to generate maps that represented the foveal pit contour and calculate its area for each patient. The mean FPC area was 3.93±0.85 mm2 in the entire group. Area of FPC decreased with each decade of life from 10 to 50 years, then increased in 5th decade and was lower again in 7th and 8th decade.
Foveal pit contour is a new parameter that enhances our current evaluation of the fovea. Its area varies with age in healthy subjects. Further studies are required to explore if it can provide an aid in clinical differentiation between normal and pathologic macular conditions.
