Diplopia following blepharoplasty.

The complication of extraocular muscle palsy following blepharoplasty is rare. In a review of 920 blepharoplasties at Manhattan Eye, Ear and Throat Hospital, three well-documented cases of diplopia following blepharoplasty could be found. Only one of these cases resolved within two months postoperatively. The explanation offered for this phenomenon is a Volkmann type contracture of the extraocular muscles following edema and hemorrhage into the muscle sheath.

Use of sclera and liquid collagen in the camouflage of superior sulcus deformities.

The cosmetic deformities following enucleation are often unavoidable. Loss of orbital volume and atrophy of orbital fat create significant enophthalmos. The literature is filled with numerous procedures that add to the orbital volume of the anophthalmic socket. An outline of three procedures to the upper eyelid to camouflage an enophthalmic appearance are presented. These can be used alone or in conjunction with an "orbital volume increasing" procedure. Two procedures can be used in an office setting to alleviate small deformities; 19 patients have been treated in this manner with a follow-up period of up to 26 months.

Dacryoadenopexy as a recognized factor in upper lid blepharoplasty.

The recognition of a herniated lacrimal gland is done by simple examination; it is not usually taught to plastic surgeons. Fullness in the superotemporal aspect of an upper eyelid in younger patients often represents a ptotic gland. Suspension of the glands improves the surgical result of upper-lid blepharoplasty without compromising lacrimal outflow.

Preparation of split thickness auricular cartilage for use in ophthalmic plastic surgery.

Auricular cartilage can be used extensively in a number of procedures by the ophthalmic plastic surgeon. It is ideal for the lengthening of eyelids, and also has a place in eyelid reconstruction, surgery for trichiasis, and the anophthalmic socket. It is vital that the cartilage be prepared in a precise and meticulous manner in order to insure optimum results.

Cryopexy of a choroidal melanoma.

Transconjunctival cryopexy was applied to a malignant melanoma of the ciliary body and choroid of a 46-year-old white man. The tumor immediately became gray-white and pigment cells were liberated in the anterior chamber. Subsequently, an enucleation was performed which showed a localized area of cryodestruction of the melanoma which was lined by macrophages. The significance of this finding in implications for the use of cryopexy in the management of melanomas are discussed.
