Retinal detachment following cataract surgery with capsulorhexis.

PURPOSE: To estimate the incidence of retinal detachment after cataract surgery with capsulorhexis. METHODS: A consecutive series of 2,150 cataract operations were followed for incidence of retinal detachment. A series of 1,000 patients from this group were analyzed for high risk factors: myopia, age, sex, operative complications and capsulotomy. RESULTS: With minimum one year follow up in 90% of patients the incidence of retinal detachment was 0.25% (5 cases). CONCLUSION: The true incidence of retinal detachment after cataract surgery remains elusive. There is probably a trend toward lower incidence compared to previous reports.

Minimally invasive lower eyelid blepharoplasty.

BACKGROUND: Transconjunctival lower eyelid blepharoplasty can significantly reduce the incidence of postoperative eyelid retraction and ectropion encountered with the traditional transcutaneous approach. These complications rarely are encountered because no scarring is induced at the level of the orbital septum and post-orbicularis facia. METHODS: A modification of the transconjunctival blepharoplasty procedure is described in which two small buttonhole incisions are used for fat removal. This procedure was performed in 148 eyelids. RESULTS: All patients had a subjective improvement of eyelid puffiness after the procedure. Lower eyelid retraction or ectropion did not develop in any of the patients. Two patients were concerned with residual eyelid puffiness and redundant eyelid skin. CONCLUSION: The primary advantages of the minimally invasive transconjunctival blepharoplasty are the ease in performing the procedure and the reduction of disruption of the conjunctival surface.

Ophthalmomyiasis externa: a case report.

A three-year-old white male presented with an extremely painful abscess of the nasal portion of the right upper eyelid. A larva identified as family Cuterebridae, genus Cuterebra sp, was removed from the abscess, permitting its rapid resolution. This represents an unusual patient with external ophthalmomyiasis who enjoys excellent nutritional and environmental surroundings.

Simplified aponeurotic ptosis surgery.

I present a simplified aponeurotic ptosis repair that minimizes surgical dissection and enhances the predictability of postoperative eyelid positions. Indications for the procedure are unilateral ptosis, bilateral ptosis where preaponeurotic fat excision is not indicated, mild congenital ptosis, and reoperations from standard levator surgery. The procedure is best suited for surgeons who have a thorough knowledge of the levator aponeurosis anatomy.

Browplasty and browpexy: an adjunct to blepharoplasty.

Surgical approaches to the eyelids and eyebrows have been refined by application of their anatomy and appreciation of their pathophysiology. Sexual variations in eyebrow appearance can be attributed in part to the eyebrow fat pad. In females, the eyebrow is generally arched and above the level of the supraorbital rim. The male eyebrow is flatter and at the level of the supraorbital rim. The eyebrow fat pad is more prominent in the male, producing a fuller appearance in the lateral brow area. Many women are concerned about the flatter, full lateral brow, which assumes a masculine quality. The authors describe a surgical technique that permits identification of the brow fat pad and then the ability to debulk the eyebrow (browplasty). In addition, the brow can be elevated by internal plication suture to physically elevate the eyebrow (browpexy). This procedure is designed to utilize an eyelid crease incision, and it reduces the indications for more involved procedures to eliminate brow ptosis, such as midforehead or coronal approaches.

Squamous cell carcinoma of the eyelids.

A clinicopathologic study of 31 squamous cell carcinomas of the eyelid was conducted. The tumor was encountered less frequently than in previous reports, due largely to the refinement of the pathologic diagnosis. Eighteen cases originally diagnosed as squamous cell carcinoma were eliminated because the diagnoses were changed to sebaceous gland carcinoma (10), basal cell carcinoma (4), seborrheic keratosis (2), inverted follicular keratosis (1), and papilloma (1). One of our 31 patients experienced tumor metastasis and tumor-related mortality. Despite the low incidence of metastasis, management recommendations include complete surgical excision using intra-operative frozen-section monitoring of the surgical margins.

Traumatic optic atrophy caused by compressed air.

A six-year-old boy who developed optic atrophy after an injury with the inner tube stem of a truck tire is described. The air stem penetrated the inferonasal portion of the left orbit and discharged air. The patient presented for evaluation within one hour and had no light perception in the involved eye. Computed tomography of the orbit revealed multiple small air bubbles surrounding the optic nerve sheath without direct optic nerve edema. It is postulated that the etiology of optic atrophy is related to the air surrounding the optic nerve, which interrupted its vascular supply. Proper covering of the air stem can prevent similar accidents.

Orbicularis muscle mobilization in eyelid reconstruction.

Mobilization of the orbicularis oculi muscle into recipient skin-graft beds was performed in seven patients. Following tumor resection, five eyelids were reconstructed using the Hughes procedure. Two eyelids had orbicularis muscle mobilization in preparation for the recipient graft site for correction of cicatricial ectropion following trauma. All skin grafts were viable and eyelid motility was enhanced. No complications were encountered.

Surgical revision of oriental eyelids.

A modified upper eyelid blepharoplasty to convert oriental to occidental-appearing eyelids is presented. The primary goal of the procedure is the creation of an eyelid crease. The recognition of the distinct anatomic features of the oriental eyelid permits the formation of a predictable and permanent eyelid crease. Satisfactory cosmetic results were produced in 14 eyelids. No complications were encountered.

Sebaceous gland carcinoma. Review of 40 cases.

The clinical and histopathologic features of 40 cases of sebaceous gland carcinoma include tumors that appeared as a localized lesion (15), diffuse chronic blepharoconjunctivitis (12), recurrent chalazion (eight), and caruncular tumors (two). In three older cases, specimens were submitted with insufficient clinical information. Chronic blepharoconjunctivitis were associated with "pagetoid" involvement of the conjunctive and lid margin. Despite the characteristic pathologic features of sebaceous gland carcinoma, correct diagnosis was given for only 22.5% of tumors on initial pathologic examination. The most common misdiagnoses were basal cell carcinoma (11) and squamous cell carcinoma (ten). Early recognition and diagnosis have substantially reduced tumor mortality. Six (24.0%) tumor deaths were encountered in 25 patients treated prior to 1970. No tumor-related mortality occurred in the 15 patients encountered after 1970.

Oriental eyelids. An anatomic study.

Dissection of the eyelids and sagittal sections of the orbital blocks identified the anatomic features of the oriental eyelids responsible for their unique appearance. The basic distinction involves the formation of the eyelid crease and fold. In the occidental eyelid, the orbital septum fuses with the levator aponeurosis below the superior tarsal border. However, in the oriental eyelid, the orbital septum fuses with the levator aponeurosis below the superior tarsal border. The accompanying preaponeurotic or orbital fat is allowed to proceed to the anterior tarsal surface, resulting in a full or thickened eyelid. The inferior extension of the orbital septum, beyond the superior tarsal border, prevents anterior aponeurotic fibers from fanning toward the subcutaneous tissues to produce the normal eyelid crease. Appreciation of the unique anatomic features of oriental eyelids is important for those persons who evaluate or surgically explore these eyelids.

Factors in the successful surgical management of basal cell carcinoma of the eyelids.

We studied the clinical and histopathologic features of 165 basal cell carcinomas of the eyelids and classified the tumors into four types (nodular, ulcerative, morphea, and multicentric) that differ in incidence, results of incomplete excision, aggressiveness, and recurrence. The value of frozen-section monitoring of the surgical margins was evident. In 39 cases excised with monitoring of the surgical margins by frozen sections, there were no recurrences. In 126 cases treated by excisional biopsy without frozen-section monitoring, 34 (26.9%) were incompletely excised and seven (5.5%) recurred. The surgical treatment of basal cell carcinoma should always include the use of frozen-section monitoring of the surgical margins. This is especially important in the morphea, multicentric, and ulcerative types, in which the invasive extent of the tumor is often not apparent clinically. These forms are also more aggressive.

The use of sclera in the treatment of dysthyroid eyelid retraction.

The use of sclera for correcting dysthyroid lid retraction is described. Forty-three procedures on 14 patients are reviewed. Of these 43 procedures, 18 were for upper eyelid retraction, and 25 were for lower eyelid retraction. A tapered graft, larger temporally, was used for the upper eyelid. An eliptical graft of uniform vertical height was used for lower eyelid. Moderately predictable results were obtained; 66% of patients were corrected to within 1 mm of desired positions after the first operative procedure. Only 13% of patients required additional surgery. When secondary procedures were required, the eyelids were corrected to the desired location. Complications were minimal. Sclera proved to be an excellent graft material for dysthyroid eyelid retraction.

Racquetball as an ocular hazard.

Thirty-seven cases of ocular injury incurred while persons were playing racquetball were found in reviewing records of 1,071 emergency room patients in a three-month period. These can be divided into ball-induced and racquet-induced injuries. Fifteen ball-induced injuries occurred, ranging from a corneal abrasion to vitreous hemorrhage, in a patient with sickle cell retinopathy. Twenty-two cases of racquet-induced brow lacerations that occurred when the player struck his (or her) own forehead with the racquet were found. During the same interval, five tennis-related ocular injuries were observed. Ocular safety devices are strongly recommended to help prevent racquetball injuries.

Lid lesions of childhood: a histopathologic survey at the Wilmer Institute (1923-1974).

This study reports 398 excised eyelid lesions in 385 children from birth through age 15. This study analyzes and discusses the clinical and histological features of the 34 types of lesions which were encountered. This tabulation serves as a guide to the physician when confronted with lid lesions in children as to the types of lesions which may be found. More importantly, however, this study is the first comprehensive clinco-pathologic evaluation of eyelid lesions in children, a topic which had previously been written and discussed in a fragmentary manner. This study analyzes data from the Wilmer Institute during 1923-1974.
