Visual field loss in primary gaze and reading gaze due to acquired blepharoptosis and visual field improvement following ptosis surgery.

Acquired blepharoptosis has been associated with loss of the superior visual field (SVF) in primary gaze. Because many patients with acquired blepharoptosis complained of difficulty reading or performing other visual functions in reading gaze, a prospective study was undertaken to determine if acquired blepharoptosis was the cause of these visual dysfunctions. Preoperative and postoperative SVFs were tested in primary gaze and reading gaze in 19 patients with unilateral or bilateral acquired blepharoptosis totaling 30 eyes. Preoperative testing revealed a marked loss of the SVF in both primary gaze and reading gaze. All patients underwent levator aponeurosis defect repair. Postoperative results showed a significant improvement in both primary and reading gaze SVFs. Therefore, patients with good visual acuity complaining of difficulty reading or carrying out other visual functions in reading gaze should be examined for the presence of acquired blepharoptosis. Blepharoptosis repair can be expected to improve the SVF in both primary gaze and reading gaze.

Axial dynamic compression plates in the management of complex orbital fractures via transconjunctival orbitotomy.

We describe our 4 years' experience using axial dynamic compression plates in the management of 46 zygomatico-orbital and complex infraorbital fractures. Surgical exposure of the fracture sites was accomplished in all cases by transconjunctival orbitotomy with lateral cantholysis. Transconjunctival orbitotomy with lateral cantholysis provides excellent surgical exposure of periorbital fractures, and axial dynamic compression plates are an excellent method for repairing these fractures.

Ophthalmic surgical management of facial paralysis.

Combinations of these procedures have been performed on more than 50 patients to date, with the longest follow-up being greater than 8 years. All of these patients presented with complaints of ocular irritation, tearing, photophobia, and impaired vision. Several had severe epithelial keratopathy. Some patients have also been treated following neurosurgical procedures which caused paralysis of the fifth and seventh cranial nerves, resulting in both corneal anesthesia and facial paralysis. Patients have done very well after these procedures and have achieved ocular comfort, reduced tearing, and corneal protection without the need for disfiguring and visually occluding tarsorrhaphies or other procedures. In some instances, they may still require artificial tears during the day or a lubricating protective ointment for the eye at bedtime. There have been no significant complications in this series; no cases of gold weight extrusion, recurrent ectropion, or persistent corneal epithelial keratopathy. Some patients have complained of continued excessive tearing which is most likely due to paralysis of the lacrimal pump, resulting in ineffective tear drainage to the nasal lacrimal duct. However, these patients have still noted markedly reduced tearing compared to their preoperative condition. One patient underwent secondary release of her medial canthoplasty following return of facial nerve function.(ABSTRACT TRUNCATED AT 250 WORDS)

Eyelid tattooing.

Tattooing has recently regained popularity in medicine. Cosmetic blepharopigmentation for eyelid enhancement by permanent eyeliner has received considerable attention. In addition, permanent pigmentation has been used for eyebrow simulation, camouflaging of scars, nipple areolar pigmentation following breast reconstruction, and the management of several other pigment disorders. This article emphasizes the principles and technique of blepharopigmentation.

Light and electron microscopic findings with permanent eyeliner.

Pathologic studies were performed on two specimens of eyelid that had been treated with permanent eyeliner (tattooing with ferrous oxide), one specimen excised four days after injection of the pigment, and the other obtained 12 months later. Each patient had undergone an ectropion repair of the lower eyelid that provided the specimen. The specimen studied four days after injection revealed by light microscopy scattered pigment granules within the epidermis and fine granules and small aggregates dispersed within the dermis. No acute or chronic inflammatory cells were observed in relationship to the deposits. The specimen obtained 12 months after eyeliner injection was studied by both light and electron microscopy. No pigment particles were observed within the epidermis, but rather there were coarse clumps of granular material in the dermis. Apart from scattered mast cells, which occasionally contained fine granules, and apart from the macrophages which appeared to have ingested the pigment granules, no other acute and chronic inflammatory cells were found. Electron microscopy demonstrated that while most of the granular material had been phagocytosed by macrophages, occasional granules were found in small dispersions within the cytoplasm of mast cells and fibroblasts of the dermis. Minimal migration of pigment within macrophages occurred to locations around lymphatic channels and within the superficial orbicularis muscle connective tissue.

Vertical tarsal buckling as a complication of levator aponeurosis repair for acquired blepharoptosis.

In two patients (a 60-year-old man and a 69-year-old woman) vertical buckling of the superior tarsus followed surgery to correct levator aponeurosis disinsertions for the management of acquired upper eyelid blepharoptosis. The superior tarsus rotated posteriorly and folded on itself because the sutures reattaching the levator aponeurosis to the tarsus were placed too low on the anterior tarsal plate. This complication can be prevented by placing the tarsal sutures above the vertical midpoint of the tarsus. If this complication develops, early correction is possible by revising the suture heights and keeping the tarsus flat with a symblepharon ring. This led to a satisfactory outcome in one of our cases. Late correction of vertical tarsal buckling requires excision of the buckled tarsus and repositioning the levator aponeurosis sutures. In one of our patients, an entropion developed as a result of insufficient vertical tarsal height that caused instability of the upper eyelid. The outcome was otherwise satisfactory.

Acquired ptosis in patients undergoing upper eyelid blepharoplasty.

Involutional or senile ptosis may be present in patients undergoing upper eyelid blepharoplasties. Several patients have been seen who have requested removal of excess upper eyelid skin when they actually required ptosis surgery. Other patients have undergone blepharoplasties and recognized the presence of ptosis following their cosmetic surgery. The ptosis was either present but unrecognized prior to surgery or developed following their blepharoplasties. Finally, some patients have required combined ptosis repair and upper eyelid blepharoplasties. This article aims to make the surgeon performing eyelid surgery aware of the potential presence of ptosis in patients undergoing blepharoplasties and assist in appropriate workup and management of these patients.

The recognition of acquired ptosis in patients considered for upper-eyelid blepharoplasty.

Involutional or senile ptosis commonly occurs simultaneously with dermatochalasis. Levator aponeurosis dehiscence or disinsertion is the most common etiology of acquired involutional ptosis in our practice. The presence of ptosis should be ascertained prior to performing an upper-lid blepharoplasty. The surgical repair of a levator dehiscence or disinsertion can be performed simultaneously with a blepharoplasty or may be the indicated procedure rather than a blepharoplasty. The recognition and appropriate management of acquired ptosis will provide better cosmetic and functional surgical results in patients undergoing upper-eyelid surgery.

Metastatic endophthalmitis: a complication of meningococcal meningitis.

A 13-month-old child with Neisseria meningitidis developed bilateral metastatic endophthalmitis. Treatment with systemic and periocular injections of penicillin G and steroids resulted in resolution of the meningitis and the endophthalmitis. This case should alert the pediatrician to the possibility of binding endophthalmitis in a patient with meningitis and ocular abnormalities.

Surgical management of congenital eyelid coloboma.

Congenital eyelid colobomas are a partial or total absence of eyelid structures. The degree of severity determines the surgical techniques employed for repairing the eyelid. We feel that early surgical treatment reduces the risk of ocular scarring with satisfactory results. We present four cases of congenital upper eyelid colobomas of differing severity and discuss surgical approaches to these lid abnormalities.

Correlation of computed tomographic and histopathologic features in malignant transformation of benign mixed tumor of lacrimal gland.

A 65-year-old man had painless progressive proptosis of five years' duration in his left eye. Sudden increase of the proptosis required a lateral canthotomy. A lateral orbitotomy was performed and a large, encapsulated, globoid mass was totally excised. Histopathologic diagnosis was adenoid cystic carcinoma arising in and surrounding a benign mixed tumor of the lacrimal gland. The computerized tomographic features correlated quite accurately with the gross appearance and histopathologic findings observed in the lacrimal gland mass. The authors discuss the clinical and radiographic features that should alert the clinician to the possibility of malignant transformation in a benign mixed tumor of the lacrimal gland.
