[Unilateral ptosis in the background of unilateral corneal arcus lipoides -- a case report]

Arcus lipoides corneae is a common bilateral degenerative disorder with ageing but only rarely occurs unilaterally. Clinically visible cream-coloured ring-shaped corneal opacities are caused by excessive lipoid deposits in the corneal stroma. Our aim is to discuss theoretical aspects of the possible impact and pathomechanism of unilateral ptosis in unilateral arcus lipoides.

The authors report the case of a 70-year-old female patient who was treated for chronic pancreatitis and hyperlipoproteinemia. She had congenital ptosis on the left side, and an arcus lipoides corneae in her left eye. The patient underwent extracapsular cataract extraction, and irregular high-grade astigmatism developed. An irregularity of the wound healing was apparent from the keratometric values, which decreased after removal of the corneal sutures.

The known etiological factors of unilateral arcus lipoides, like contralateral stenosis of the internal carotid artery, traumatic or iatrogenic hypotony, chronic iridocyclitis of the eye were absent in our patient.
