Myiasis of the exenterated orbital cavity: Case report and video.

Purpose: We present an unusual case of myiasis involving the orbital cavity.

Observations: Our patient had undergone orbital exenteration one month prior to presentation. Post-operatively, he presented with multiple, highly mobile larvae in the orbital cavity.

Nasolacrimal duct office probing in children under the age of 12 months: Cure rate and cost evaluation.

Introduction: Controversy exists regarding the treatment of infants with symptomatic nasolacrimal duct obstruction. One philosophy advocates "early" nasolacrimal duct probing, generally in the office - a relatively common approach in France, while others prefer to wait until the age of 12 months to offer a procedure under general anesthesia. The goal of this study is to report results of immediate office probing for congenital nasolacrimal duct obstruction (CNLDO) under age 1 year in terms of efficacy and cost.

Optic neuropathy in thyroid eye disease: results of the balanced decompression technique.

Objective: To determine the efficacy of combined endoscopic medial and external lateral orbital decompression for the treatment of compressive optic neuropathy (CON) in thyroid eye disease (TED).

Design: A retrospective review of all patients undergoing combined surgical orbital decompression for CON between 2000 and 2010 was conducted.

Participants: Fifty-nine eyes of 34 patients undergoing combined surgical orbital decompression for CON.

Altered expression of the poly(ADP-ribosyl)ation enzymes in uveal melanoma and regulation of PARG gene expression by the transcription factor ERM.

Purpose: Poly(ADP-ribosyl)ation is a reversible post-translational modification that requires the contribution of the enzymes poly(ADP-ribose) polymerase-1 (PARP-1) and poly(ADP-ribose) glycohydrolase (PARG). Our study explores expression and activity of PARP-1 and PARG in uveal melanoma cell lines with varying tumorigenic properties.

Methods: Gene profiling on microarrays was conducted using RNA prepared from the uveal melanoma cell lines T97, T98, T108, and T115.

Orbital decompression in Graves' orbitopathy: a combined endoscopic and external lateral approach.

Aims: First, to assess the outcomes of endoscopic and external lateral orbital decompression in patients with dysthyroid orbitopathy. Second, to establish a correlation between the percentage of postoperative diplopia and the technique used.

Methods: A retrospective review of 40 patients (73 eyes) who underwent endoscopic medial orbital decompression and external lateral orbital decompression between 1997 and 2003 at the Hôpital Enfant-Jesus in Quebec City.

Surgical correction of blepharoptosis in oculopharyngeal muscular dystrophy.

Progressive, usually symmetric blepharoptosis with or without dysphagia appears in most instances in the fifth decade in oculopharyngeal muscular dystrophy (OPMD). We review our experience over 20 years of applying Beard's surgical guidelines for correction of ptosis to OPMD patients with satisfactory results. As the disease continues to progress, the rate of recurrence of ptosis among follow-up patients of a 9-year minimum period was 13%.

Comparative study of wound healing in porcine skin with CO2 laser and other surgical modalities: preliminary findings.

Background: The CO2 laser is a common surgical modality in dermatology. To clarify conflicting reports on the histological healing properties of CO2 laser on incisional or ablative wounds, we have applied it in a miniature hairless porcine skin model at power settings similar to those used in clinical practice.

Methods: Histological parameters of wound healing in skin incisions using the CO2 laser were compared with those using scalpel, hot scalpel, and electrosection, and in dermal ablation using CO2 laser, fraize, wire brush, and electrofulguration alone or with curettage.

Buccal mucous membrane-fat graft in the management of the contracted socket.

A new surgical technique for reconstructing severely contracted sockets using an autogenous buccal mucous membrane-fat graft is presented. The buccal mucosa provides replacement of deficient conjunctival surface area; the fat in the underlying substantia propria of the buccal mucosa replenishes moderate volume deficiency in a single procedure. A custom-designed conformer is used in the immediate postoperative period to maintain reconstructed vertical fornices.

Experimental treatment of eyelashes with high-frequency radio wave electrosurgery.

Apart from mechanical epilation, which is a nuisance to both the patient and the ophthalmologist, standard techniques for removing unwanted eyelashes, such as electrosurgery (Hyfrecator) and cryosurgery, may cause eyelid tissue damage and other complications. Refinements in electrosurgical techniques have enabled production of a machine that can provide high-frequency radio waves with a modification of the waveform to produce a blended cut-coagulation effect (Ellman Surgitron). Treatment of hairs in fresh calf skin with the Ellman Surgitron resulted in destruction of the germinal cells of the hair follicle, with only a small amount of tissue change lateral to the track of the electrode; the Hyfrecator caused total sloughing of the epithelial cells, with marked superficial tissue changes due to heat spread.

High-frequency radio wave electrosection of full-thickness eyelid tissues.

The Ellman Surgitron, commonly used in dermatology practice, is an electrosurgical instrument with a high-frequency waveform that is modified by filtering and undamping the current so that an almost pure cut is possible, yet with a small amount of coagulation. This device was used in six patients undergoing full-thickness eyelid resection (unilateral in three and bilateral in three) for involutional entropion or ectropion. Nine lid margins were cut with scissors, and nine with the electrosurgical instrument.

Correction of blepharoptosis in oculopharyngeal muscular dystrophy: review of 91 cases.

Oculopharyngeal muscular dystrophy is a progressive, hereditary myopathy in which the levator palpebrae and the pharyngeal muscles are selectively involved. Progressive, usually symmetric blepharoptosis with or without dysphagia appears in the fifth decade. The high prevalence of this myopathy in Quebec stems from the immigration of a single couple from France in 1634, whose numerous descendants manifest its autosomal dominant heredity.
