Anatomy of the terminal nerves in the upper eyelid.

Anatomic dissections on human cadaver heads were performed to determine the anatomy of the terminal nerves in the upper eyelid. Vertically oriented nerves, which are commonly identified in a preseptal location in the upper eyelid, were determined to be sensory nerves, most commonly originating from the supraorbital nerve (V1). Facial nerve (VII) dissections were also performed, with specific attention paid to the temporal branch. The facial nerve innervates the orbicularis muscle on its deep surface, both at the most temporal aspect of the muscle as well as along the supraorbital rim. No motor fibers could be traced into the upper eyelid and no anastomosis was noted between the temporal branch of the facial nerve (VII) and the supraorbital nerve (V1).

Retinal detachment as a complication of retrobulbar anesthesia.

The authors report an unusual case of retinal detachment after cataract surgery in a 48-year-old man in which it appeared that the retrobulbar needle passed through the sclera and tracked beneath the retina before perforating the retina superior to the disc. The cause of the detachment was not clearly defined until a depigmented line was observed after reattachment of the retina.

Nodular fasciitis presenting as an eyelid mass.

A case of nodular fasciitis occurring in the eyelid is presented. The clinical and pathologic features of this rare cause of an eyelid mass are discussed. Nodular fasciitis should be considered in the pathologic differential diagnosis of connective tissue tumors of the periorbital region. It is important not to confuse nodular fasciitis with fibrosarcoma, as simple excision is curative for this condition.

Congenital ptosis in monozygotic twins.

A case of concordance for unilateral congenital ptosis in monozygotic twins is presented. The literature on genetics and congenital ptosis is reviewed. A heritability index is calculated for congenital ptosis, based on all current twin data including the present report. A value for the heritability index of 0.75 is found, suggesting a strong hereditary influence for congenital ptosis. We conclude that twin data strongly support a transmissable genetic defect as contributing to the development of congenital ptosis.

Levator aponeurosis surgery. A retrospective review.

A review of all cases of aponeurotic repair done since 1980 by the author identified 140 patients and 174 eyelids. An acceptable result at 6 weeks was defined as a lid level within 1 mm of the desired level achieved in 74% of lids with acquired ptosis. The amount of ptosis present preoperatively was the major factor in our study; levator function and type of anesthesia did not affect the success rate. The most significant finding was a lower long-term success rate due to a drop in lid level clustered at the 2- to 4-month period postoperatively. The authors speculate on the cause for this finding.
