Prevalence of floppy eyelid syndrome in obstructive sleep apnea-hypopnea syndrome.

OBJECTIVES: To determine the prevalence of floppy eyelid syndrome (FES) in obstructive sleep apnea-hypopnea syndrome (OSAHS) and to develop a method to measure eyelid laxity. DESIGN: Masked cross-sectional (prevalence) study examining patients referred to the Mayo Sleep Disorders Center. PARTICIPANTS AND/OR CONTROLS: Fifty-nine subjects were examined before undergoing polysomnography. Forty-four subjects had OSAHS, and 15 did not have it. TESTING: Subjects underwent slit-lamp examination and eyelid laxity measurements, followed by polysomnography. MAIN OUTCOME MEASURES: Presence of FES as defined by subjectively easy eyelid eversion, tarsal papillary conjunctivitis, and lash ptosis; force required to displace the upper lid 5 mm, as measured by a strain gauge device; number of apnea or hypopnea episodes per hour (apnea-hypopnea index [AHI]); presence of OSAHS, as defined by an AHI of > or =5; and abnormalities on electrocardiography. RESULTS: One patient with OSAHS was found to have FES, yielding a prevalence of 2.3% (95% confidence interval [CI]: 0.1%-12.0%). One patient was referred to the Sleep Disorders Center due to a diagnosis of FES; if this patient were included, the prevalence would be 4.5% (95% CI: 0.5%-15.1%). Subjectively easy lid eversion was more common in OSAHS patients than in non-OSAHS patients. When adjusted for age and body mass index, there was a trend for association between subjectively easy lid eversion and OSAHS, but this did not reach statistical significance. Subjectively easy lid eversion was associated with AHI. Force required to displace the upper lid 5 mm was lower in lids with subjectively easy eversion, but was not associated with OSAHS or AHI. Intraclass correlation among 3 strain gauge measurements was good for both right (82%) and left (83%) lids. There were no statistically significant differences in frequency of electrocardiographic abnormalities among the various groups. CONCLUSIONS: The prevalence of FES among OSAHS patients is low. Patients with subjectively easy upper lid eversion are at risk for OSAHS. By recognizing the potential for OSAHS in these patients, the ophthalmologist may play an important role in initiating their evaluation and treatment.

Height of the tarsus of the lower eyelid.

The vertical height of the lower eyelid tarsus of 20 patients submitting to lower eyelid resections and the lower tarsus of 17 cadavers was 3.7 mm (+/- 0.3) and 3.9 mm (+/- 0.5), respectively. The average value found in our patients was statistically different (P less than .05) than the values of 5 to 7 mm reported previously. The lower tarsus should be clearly identified in procedures involving eyelid repair or eyelid reconstruction so that tension-bearing sutures can be placed through the tarsus.

Disorders of the lids.

Included in the discussion is the management of anomalies of abnormal formation of the lid folds, disorders of differentiation of the lid margins, and disorders of tissue differentiation. Also discussed are lid involvement with bacterial lesions and viral diseases.

Reconstruction of the eyelid using a myocutaneous island flap.

Traditionally, skin flaps have been based upon a contiguous skin pedicle. Recently the concept has re-emerged that the important blood supply frequently lies subjacent to the flap. A temporally based island flap composed of skin and orbicularis muscle, nourished only by its subjacent pedicle, has been successfully used in the reconstruction of 91 eyelid defects.

Eyelid and orbital treatment following radical maxillectomy.

Malignant lesions of the nasopharynx and paranasal sinuses often encroach upon the orbit. A series of nineteen patients who underwent partial or radical maxillectomy is presented to summarize the eyelid and orbital findings that required further treatment. Fifteen of these patients were left with an intact globe and a visually useful eye, but the defects of epiphora, eyelid malposition, dacryocystitis, and diplopia were visually threatening and required treatment. The cosmetic deformities and diplopia following maxillectomy and radiation are partially amenable to treatment with late bone grafting. Lacrimal outflow deficiencies were successfully treated with dacryocystorhinostomy. Only patients with ocular complications following maxillectomy are included in this series; therefore, the range of problems and their treatment confronting the ophthalmologist is summarized.

Diagnosis and treatment of postoperative complications after skin resurfacing.

Chemical peel, dermabrasion, and laser skin resurfacing are alternative methods to achieve skin resurfacing for reconstructive or cosmetic applications. The potential postoperative complications are similar with all of these techniques. These postoperative complications and their therapy are reviewed.

Distribution and depression of the GABA(B) receptor in the spinal dorsal horn of adult rat.

gamma-Aminobutyric acid (GABA) is a principal inhibitory neurotransmitter in vertebrate nervous system. The metabotropic receptor for GABA, GABA(B) receptor, is characterized as a G protein-coupled receptor subtype. In the present study, GABA(B) receptor-like immunoreactivity (GABA(B)R-LI) in the rat spinal cord and dorsal root ganglion (DRG), as well as GABA(B) receptor-mediated depression in the spinal dorsal horn were examined by using immunohistochemistry and whole-cell voltage-clamp recording technique, respectively. Under light microscope, GABA(B)R-LI was densely found in laminae I and II of the dorsal horn. DRG cells of various diameters also showed GABA(B)R-LI. Electron microscopy further revealed that GABA(B)R-LI was also localized in terminals of myelinated, unmyelinated fibers as well as the somatodendritic sites of dorsal horn neurons. Bath application of a GABA(B) receptor agonist, baclofen (10 microM, 30 s), induced a slow outward (inhibitory) current in dorsal horn neurons. This slow current was depressed when the postsynaptic G protein-coupled receptor was inhibited, indicating the postsynaptic action of baclofen. Under the condition of postsynaptic GABA(B) receptor being inhibited, baclofen (10 microM, 60 s) depressed large (Abeta) and fine (C, Adelta) afferent fiber-evoked monosynaptic excitatory postsynaptic currents, indicating presynaptic inhibition of GABA(B) receptor on elicited neurotransmitter release. Taken together, the results suggest that baclofen-sensitive GABA(B) receptor is expressed pre- and postsynaptically on primary afferent fibers and neurons in the spinal dorsal horn; activation of GABA(B) receptor in the dorsal horn postsynaptically hyperpolarizes dorsal horn neurons and presynaptically inhibits primary afferents.

Transconjunctival approach to zygomatic and orbital floor fractures.

The authors present their experience with transconjunctival approach to access the orbital floor, infraorbital rim and zygomatic-frontal and zygomatic temporal sutures in 40 patients with fractures in the orbital and zygomatic region. The preseptal and retroseptal approaches are described. Despite the complication rate of 12.5%, the esthetic results and simultaneous visualization of the infraorbital rim and lateral orbital rim supports the use of the transconjunctival approach.
