The complications of dermal tattooing.

Dermal tattooing has been performed for over 4,000 years. Some of the reported complications from tattooing include pyogenic infections, viral hepatitis, syphilis, tuberculosis cutis, rubella, herpes simplex, herpes zoster, psoriasis, lichen planus, lupus, pigment allergy and sensitivity, keloids, sarcoidal granulomas, erythema multiforme, malignant melanoma, squamous cell carcinoma, and basal cell carcinoma. Most complications can be avoided by utilizing proper aseptic technique and avoiding exotic pigments. A survey of the members of the American Society of Ophthalmic Plastic and Reconstructive Surgery was taken to determine the prevalence of eyelid tattooing and complications encountered. The findings of this survey are presented.

Treatment of Aspergillus fumigatus keratitis in rabbits with oral and topical ketoconazole.

Aspergillus fumigatus keratitis was established in rabbits by intrastromal injection of a suspension containing 5,000 spores. After a 48-hour incubation period, the animals were treated with oral and topical ketoconazole alone and in combination with topical natamycin for five days. Colony counts per cornea were obtained at the conclusion of the treatment period. Based on these colony counts, neither oral nor topical ketoconazole was effective despite moderate in vitro sensitivity of the fungus to ketoconazole. Oral and topical ketoconazole used in conjunction with natamycin, however, appeared to augment sterilization of A. fumigatus in this model of fungal keratitis.

Jones tube visualization.

Postoperative follow-up of a Jones tube is simplified by utilizing the fiber optic properties of the pyrex tube. Light directed onto the external tube collar is transmitted to the intranasal end of the tube, causing it to glow and highlight the surrounding intranasal anatomy.

Malignant melanoma of the orbit in a black patient with ocular melanocytosis.

Ocular melanocytosis has been associated with an increased incidence of choroidal melanomas in white patients. Recently reported was a case of a choroidal melanoma in a black patient with oculodermal melanocytosis. We treated a case of an orbital malignant melanoma arising in a black patient with ocular melanocytosis.

Nonincisional correction of epiblepharon and congenital entropion.

Nonincisional suture techniques are used for the treatment of epiblepharon and congenital entropion. An explanation for the unstable eyelid seems to involve similar developmental anomalies of the eyelid retractor. Congenital entropion has been treated promptly in the past. Contrary to tradition, symptomatic epiblepharon should also be treated early.

Lacrimal sac identification in dacryocystorhinostomy surgery.

The intraoperative identification and opening of the lacrimal sac is generally performed by cutting down on the tip of a lacrimal probe passed down one canaliculus. While easily performed in most cases, this step is frequently associated with difficulty, confusion, and orbital fat exposure particularly if the internal common punctum is imperforate or the sac is scarred. The authors present an alternate method for opening the sac based upon simple anatomic concept.

Principles of cryosurgery.

The mechanism by which a cryogen destroys cells is complex. The formation of a hemispherical iceball composed of thermogradients, each of which maintains a temperature proportional to its distance from the application point, initiates the cryoinjury. The cardinal rule of cryosurgery includes a rapid freeze, which produces highly damaging intracellular ice formation and closely-packed thermogradients, coupled with a slow thaw. Multiple freeze/thaw cycles are most destructive, producing ischemic necrosis. Histological and clinical aspects are discussed, as well as complications and follow-up procedures.
