Description of intervention(s) / exposure
Assessment entails a non-mydriatic optical coherence tomography in addition to a comprehensive ophthalmologic evaluation done at the military hospital for adult subjects who happen to be accompanying patients. This single assessment session lasts about 90 minutes It is not repeated. The non mydriatic OCT image is sent to a reading center electronically to be evaluated by a reader.

Outcomes
Primary outcome [1] 298053 0
Rate of detection of irregularities in the foveal area assessed by non-mydriatic Optical Coherence Tomography.
Timepoint [1] 298053 0
90 minutes. Each participant will have one assessment session, starting with a non-mydriatic optical coherence tomography only to be followed by a comprehensive eye evaluation.
Secondary outcome [1] 323061 0
best corrected visual acuity using the ETDRS chart.
Timepoint [1] 323061 0
15 minute; this outcome is assessed at study entry as part of the comprehensive eye examination that each study subject receives.
Secondary outcome [2] 323062 0
Thickness of the fovea using the non-mydriatic optical coherence tomography
Timepoint [2] 323062 0
15 minutes; this is measured during the image interpretation of the acquired NMOCT by the retina specialist in the reading center.

Statistical methods / analysis
Ideally we would like to screen around 500 eyes, since these abnormalities have been detected in 9% or so in general population using a comprehensive eye examination. Around 250 participant would be needed to look for asymptomatic irregularities in the fovea. Sensitivity, specificity, positive predictive value, negative predictive value, kappa coefficient

Summary
Brief summary
Purpose: To evaluate non-mydriatic spectral domain optical coherence tomography (NMOCT) as a telemedicine screening tool for adult foveal abnormalities.

Materials and Methods: two hundred and fifty middle-aged subjects will be asked to undergo a NMOCT test. These subjects will also be invited to undergo a comprehensive ophthalmologic evaluation to check for the efficacy of the NMOCT as a telemedicine screening tool in detecting foveal abnormalities.
