Over the past 3 1/2 years, 28 patients with blepharospasm have undergone, bilaterally, staged percutaneous thermolytic fractional destruction of branches of the facial nerve. This series consisted of 20 women and eight men ranging in age from 40 to 79 years, with symptoms for from 1 to over 10 years. At the time of follow-up, 12 patients had undergone one operation, 12 had had two operations, and four had had three to five operations. Sixteen of the 28 patients obtained excellent to good relief of symptoms for 1 to 3 1/2 years. The procedures performed using local anesthesia and intravenous analgesia allow the immediate recognition of any facial muscle weakness or asymmetry. The findings indicate that this procedure, in many patients with minimal complications, can significantly relieve the incapacitating symptoms of blepharospasm.

Seventeen patients with intractable blepharospasm underwent bilateral percutaneous fractional thermolytic destruction of branches of the facial nerve. Thirteen were women and four men; their ages ranged from 46 to 76 years with an average of 62 years. Since local and intravenous analgesia were used, the patients were awake and cooperative, resulting in minimal complications. In this series, patients had an average improvement of 69%. Minimal scarring results from the percutaneous route and these patients may undergo staged procedures for further relief of their symptoms.

Pain that does not respond to conventional treatment procedures makes it necessary to look for alternative methods. Acupuncture is an ancient procedure with empirical effects on pain. Previous studies established the increased output of messengers at neuronal junctions in spinal cord and hypothalamic locations, especially of endorphins which inhibit the perception of pain. We treated several painful symptoms with acupuncture and evaluated the outcome of the treatment. Patients with various kinds of therapy-refractory pain and patients in whom conventional treatment methods could not be applied were included in the study. The diagnoses included glaucoma. Tolosa-Hunt-Syndrome, ophthalmic migraine, blepharospasm, and dry eyes. In one case acupuncture was used for analgesia during surgery. Acupuncture was performed with sterile disposable needles, at points known to have an empirical analgesic effect. The stimulation was adapted to the patient's individual needs. VAS assessments before and after acupuncture were compared. The t-test was used for statistical evaluation. Acupuncture had no side effects, but reduced pain to a variable extent. Especially in cases of severe pain and in surgery, very effective pain reduction was achieved. In general, pain was significantly reduced in all patients by the use of acupuncture. A statistically significant effect was noted (p < 0.05). Further studies should be conducted to demonstrate the specific effect in larger patient populations. Monitoring neurotransmitter activity will possibly help to illustrate the effect.

Venom ophthalmia caused by venoms of spitting elapid and other snakes: report of ten cases with review of epidemiology, clinical features, pathophysiology and management. Chu, ER, Weinstein, SA, White, J and Warrell, DA. Toxicon XX:xxx-xxx. We present ten cases of ocular injury following instillation into the eye of snake venoms or toxins by spitting elapids and other snakes. The natural history of spitting elapids and the toxinology of their venoms are reviewed together with the medical effects and management of venom ophthalmia in humans and domestic animals including both direct and allergic effects of venoms. Although the clinical features and management of envenoming following bites by spitting elapids (genera Naja and Hemachatus) are well documented, these snakes are also capable of "spraying" venom towards the eyes of predators, a defensive strategy that causes painful and potentially blinding ocular envenoming (venom ophthalmia). Little attention has been given to the detailed clinical description, clinical evolution and efficacy of treatment of venom ophthalmia and no clear management guidelines have been formulated. Knowledge of the pathophysiology of ocular envenoming is based largely on animal studies and a limited body of clinical information. A few cases of ocular exposure to venoms from crotaline viperids have also been described. Venom ophthalmia often presents with pain, hyperemia, blepharitis, blepharospasm and corneal erosions. Delay or lack of treatment may result in corneal opacity, hypopyon and/or blindness. When venom is "spat" into the eye, cranial nerve VII may be affected by local spread of venom but systemic envenoming has not been documented in human patients. Management of venom ophthalmia consists of: 1) urgent decontamination by copious irrigation 2) analgesia by vasoconstrictors with weak mydriatic activity (e.g. epinephrine) and limited topical administration of local anesthetics (e.g. tetracaine) 3) exclusion of corneal abrasions by fluorescein staining with a slit lamp examination and application of prophylactic topical antibiotics 4) prevention of posterior synechiae, ciliary spasm and discomfort with topical cycloplegics and 5) antihistamines in case of allergic kerato-conjunctivitis. Topical or intravenous antivenom and topical corticosteroids are contraindicated. Clinical outcome of venom ophthalmia is largely dependent on prompt treatment and appropriate follow-up.

It is suggested that topical application of opioids may provide localized analgesia without delay in corneal wound healing. This study was designed to evaluate the effect of topical application of 0.8% nalbuphine on post-operative ocular pain in dogs. Twelve eyes from 11 dogs undergoing phacoemulsification cataract surgery were divided into a nalbuphine group (n=6) and saline group (n=6). Postoperatively, the nalbuphine group received 0.1 ml of topical 0.8% alkalinized nalbuphine (pH 5.6) every 8 hr, and the saline group received 0.1 ml of topical saline (pH 5.9) as a placebo. All dogs received systemic postoperative pain managements with oral tramadol (4 mg/kg) and prednisolone (0.5 mg/kg) every 8 hr. All dogs received pre- and post-ophthalmic examinations. Pain was scored in the dogs using a pain scoring system modified from the University of Melbourne pain scale at 15, 30 and 60 min following the topical treatment on days 1 and 2 (24 and 48 hr after surgery). Eye blink frequency and corneal touch threshold (CTT) were recorded at the same time. There was no statistical difference in the pain score between groups. Significant decreases in CTT, blepharospasm and eye blink frequency were observed after the topical nalbuphine treatment. This indicated that topical application of 0.8% nalbuphine solution can produce a rapid reduction of corneal discomfort in dogs.
