Abstract
In the era of OCT, we are often asked to make a diagnosis relying on an OCT appearance. The following cases represent two extreme varieties of unusual foveal conditions. The first is foveal hypoplasia which may be isolated or associated with other ocular conditions and characterized by the continuity of the inner retinal layers in the fovea with variable degrees of decreased foveal pit and absence of cone specialization. Decreased visual acuity and nystagmus may be present, dependent on the degree of hypoplasia. The improved resolution of OCT helps to diagnose and differentiate the degree of foveal hypoplasia. The second condition is a “double fovea” configuration on OCT which was first suspected to be an evolutionary remnant of ancient foveal configuration presently found in birds. A careful clinical examination and using a different scanning plane helped to discover the reason of this unusual appearance on OCT. Both examples show that OCT is a very important tool for diagnosing and characterizing different foveal conditions but is an adjunct to a careful clinical examination and that its interpretation is meaningful only in that context.
