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. In six eyelids of six patients undergoing eyelid excision the Ellman Surgitron was effective in causing destruction of the germinal cells of the hair follicle, with very little lateral heat spread in the tissues or destruction of the skin epithelial cells. As well, there was no tissue damage anywhere near the conjunctival surface.

An eyelash in the vitreous cavity without apparent etiology.

Intraocular eyelashes are an infrequent complication of trauma to the eye. Intraocular cilia have a variable prognosis ranging from acute inflammation to remaining dormant within the vitreous for several years. However, intraocular cilia in the anterior chamber have been associated with delayed inflammatory responses, while intravitreal cilia may cause rhegmatogenous retinal detachment. All cases reported in the literature to this point have been able to identify some history of trauma, be it acute or remote. In this report a case is described in which intravitreal cilia were not associated with a history of trauma.

Predicted effect compartment concentration of thiopental at loss of eyelash reflex.

We derived the predicted effect compartment concentration of thiopental, at loss of the eyelash reflex, following three different injection regimens. Sixty patients were given thiopental for induction of anaesthesia. Twenty patients received multiple small boluses, 20 patients received a single bolus and 20 patients received an infusion. Computer simulation was then used to derive the effect compartment concentration. The median concentration was not significantly different between the three groups. EC50, derived after combining all three groups was 11.3 microg ml(-1). The EC05-EC95 range was 6.9-18.3 microg ml(-1), suggesting wide inter-individual variation.
