Diagnosis: central corneal with a partial arcus senilis

central corneal with a partial arcus senilis

Image Comments:

The typical course of an arcus senilis: an arc begins above and below in varying intensity. The two arcs may then creep towards 9 and 3 o'clock. They may eventually meet to form a complete circle. The central corneal disease - a healed corneal ulcer - has the potentiality for a descemetocele. The classification of corneal scars according to the density of the scar is: 1. nebula - difficult to detect without increased illumunation and magnification, e.g. slit-lamp 2. macula - more easily seen with oblique illumination with a pen-light 3. leucoma - readily evident as a dense white scar under room illumination. The scar in the photo is arguably in the pre-leucoma stage, i.e. somewhere between a macular and a leucomatous stage.
