Eyelid surgery in facial palsy.

Paralysis of the orbicularis oculi muscle is by far the most serious consequences of loss of function of the facial nerve. The severity of the resultant ocular problems is related to the degree and duration of this paralysis. The primary goal of the ophthalmologist in managing the patient with orbicularis oculi paralysis is to protect the cornea. The alleviation of epiphora, correction of paralytic ectropion, and amelioration of the resultant cosmetic deformities are secondary goals. The major factor in determining the most appropriate therapeutic approach in the management of the patient with a facial paralysis is whether the paralysis is temporary or permanent. In temporary paralysis, conservative methods of treatment are usually adequate and are well documented. In permanent orbicularis paralysis, the development of lid abnormalities is inevitable, and corrective lid procedures are required. The procedures required depend on the resultant dysfunction and degree of deformity. This study reviews 65 patients who underwent surgical treatment for the ophthalmic consequences of established and permanent facial palsy in order to evaluate the efficacy of their treatment.

Three wall orbital decompression for Graves' ophthalmopathy via a coronal approach.

Ten patients with dysthyroid eye disease who underwent a three wall orbital decompression procedure performed via a coronal approach were reviewed. The indications, results, complications and surgical techniques involved in this surgery are discussed. We believe that this approach offers a number of advantages over other techniques and has a role in the management of carefully selected patients with dysthyroid eye disease who have severe unilateral or bilateral proptosis, with or without dysthyroid optic neuropathy.

Ophthalmic management of seventh nerve palsy.

The management of acute and established seventh nerve palsy is discussed with reference to corneal exposure, paralytic ectropion and the cosmetic defect. Details are given of how these can all be improved with relatively simple procedures which can be performed under local anaesthesia as an outpatient.

Cavernous haemangioma of the orbit.

Cavernous haemangioma is considered to be the most common primary orbital tumour. We present 3 cases of cavernous haemangioma of the orbit managed by medial orbitotomy combined with medial orbital decompression. This approach was performed for lesions occurring medial to the optic nerve in an attempt to reduce the surgical morbidity reported following lateral orbitotomy or transcranial orbitotomy.

Secondary lens implantation: incidence, indications and complications.

A retrospective study of 79 secondary intraocular lens implants performed during 1984-87 in a large teaching hospital is reported. The period of follow-up ranged from 6 months to 3.9 years (mean 16.6 months). The principal indication for surgery was contact lens intolerance. Thirty-four per cent of the patients had previously undergone cataract surgery with implantation of the other eye. Eighty-three per cent of the patients achieved a visual acuity within one Snellen line of best-corrected preoperative visual acuity. A further 2.5% lost two lines of Snellen chart acuity, and 14.5% had a substantial reduction in visual acuity. We conclude that in carefully selected patients secondary intraocular lens implantation is an acceptable and often highly successful way of treating monocular aphakia and we discuss the selection and preoperative investigation of such patients.

A clinical study of the hydroxyapatite orbital implant.

The hydroxyapatite orbital implant has been used in the anophthalmic patient to give good motility of the artificial eye and a cosmetic result which matches that of the natural eye. It is thought to reduce the unacceptable complication rate that has been associated with other implants, as its buried, vascularized state deters extrusion and migration of the implant. Eighty consecutive patients were followed, 33 of whom had been referred for primary enucleation or evisceration, and 47 for secondary implant surgery. Thirteen of the secondary patients already had implants in situ. There were 44 males and 36 females in the study. The age range was 2.5 to 72 years with a mean of 36 years. The follow-up time was 2 to 30 months with a mean of 15 months. Twenty patients had been pegged at the time of review. A standardised operative and post-operative protocol was followed. The patients were assessed for the results of the motility of the artificial eye for both smooth pursuit and saccades, and for the cosmetic result. The amount of upper lid sulcus deformity was assessed to give an indication of volume replacement by the implant. The nature of any complications was noted as well as any further surgical procedures undertaken. The results show the hydroxyapatite orbital implant to give good cosmetic results with good motility of the artificial eye and to be associated with a low rate of complications. Drilling of the implant is simple to perform and also not associated with any significant complications. The hydroxyapatite orbital implant can be used successfully not only as a primary but also as a secondary or exchange implant with very few contraindications.

Microphthalmos with cyst in monozygous twins.

We present two cases of microphthalmos with cyst affecting monozygotic twins. The etiology and pathogenesis of this developmental anomaly are discussed. The diagnostic evaluation, differential diagnoses, and management options of this unique disorder are also considered.
