The congenital retinocephalic facial vascular malformation syndrome is characterized by unilateral, nonhereditary retinal and cerebral arteriovenous malformations (AVMs) and is occasionally associated with orbital vascular changes. Typical signs are facial and oral mucosal vascular changes, rarely with changes of the maxilla or mandible. An AVM causes high blood flow because of direct connection (shunting) of major vessels without interposition of capillaries. Ocular complications include retinal and vitreous hemorrhages, edema, venous occlusion (risk of rubeosis iridis and secondary glaucoma). Neuroophthalmological changes comprise optic atrophy, papilledema, proptosis, pupillary changes, hemianopia, gaze paresis, nystagmus, cranial nerve palsies, strabismus, and amblyopia. Neurological complications include headache, subarachnoid hemorrhage, convulsions, cerebral hemorrhages, increased intracranial pressure, hydrocephalus, and stroke with hemiparesis. Threatening oral hemorrhages or epistaxis may rarely occur.

A 10-year-old boy with unilateral ophthalmoplegia, ptosis, and proptosis underwent diagnostic examination. Symptoms of headache, nausea, dyspnea, fatigue, weakness, and loss of appetite began 14 days after the onset of ocular manifestations and 7 days before he was examined. Complete blood count showed an increased white blood cell count with 64% blast cells, anemia, and thrombocytopenia. The patient was transferred to a pediatric hematology unit, where he underwent bone marrow aspiration biopsy. Bilateral ocular inflammatory findings and left-sided mild proptosis became evident. He was diagnosed as having B-cell non-Hodgkin lymphoma infiltrating the bilateral cavernous and sphenoid sinuses.

A 14-year-old girl had a 3-month history of headache and blurred vision. Funduscopy showed bilateral optic disc edema. Findings on brain imaging were normal, and a diagnosis of idiopathic intracranial hypertension was confirmed after lumbar puncture showed an elevated opening pressure of 32 cm H(2)O. Optic nerve head drusen were noted on computed tomography scan and confirmed with B-scan ultrasound. After 2 years, resolution of symptoms coincided with variable compliance to treatment with acetazolamide and concomitant papilledema. In general, optic disc edema poses a clinical conundrum due to the more common occurrence of optic nerve head drusen, potentially resulting in delayed diagnosis and treatment of idiopathic intracranial hypertension.

A 13-year-old boy presented with gradually progressive deterioration of vision in both eyes, bilateral photophobia, and regular headaches. Clinical examination, anterior segment findings, and specular microscopy findings were consistent with the diagnosis of posterior polymorphous dystrophy and keratoglobus. To the authors' knowledge, this is the first pediatric case and the second case overall of the simultaneous occurrence of posterior polymorphous dystrophy and keratoglobus.

Botulinum toxin A (BTX-A), a purified protein derived from the bacteria Clostridium botulinum, has been widely used in aesthetic dermatology. Though BTX-A was initially used by neurologists extensively for neurological conditions such as blepharospasm, strabismus headaches, dystonia and spasticity, it has become popular among dermatologists and plastic surgeons for its cosmetic indications. Its use in pregnancy has been controversial and this article deals with the issues of use of BTX-A in pregnancy.

Botulinum toxin, one of the most poisonous biological substances known, is a neurotoxin produced by the bacterium Clostridium botulinum. C. botulinum elaborates eight antigenically distinguishable exotoxins (A, B, C(1), C(2), D, E, F and G). All serotypes interfere with neural transmission by blocking the release of acetylcholine, the principal neurotransmitter at the neuromuscular junction, causing muscle paralysis. The weakness induced by injection with botulinum toxin A usually lasts about three months. Botulinum toxins now play a very significant role in the management of a wide variety of medical conditions, especially strabismus and focal dystonias, hemifacial spasm, and various spastic movement disorders, headaches, hypersalivation, hyperhidrosis, and some chronic conditions that respond only partially to medical treatment. The list of possible new indications is rapidly expanding. The cosmetological applications include correction of lines, creases and wrinkling all over the face, chin, neck, and chest to dermatological applications such as hyperhidrosis. Injections with botulinum toxin are generally well tolerated and side effects are few. A precise knowledge and understanding of the functional anatomy of the mimetic muscles is absolutely necessary to correctly use botulinum toxins in clinical practice.

Initially used to treat strabismus in the 1970s, botulinum toxin now has more than a hundred possible medical applications. Its utility in neurologic conditions has largely involved treating movement disorders (particularly dystonia and conditions with muscle hyperactivity), although practically any hyperkinetic movement disorder may be relieved by botulinum toxin, including hemifacial spasm, tremor, tics, myoclonus, and spasticity. Although initially thought to inhibit acetylcholine release only at the neuromuscular junction, botulinum toxins are now recognized to inhibit acetylcholine release at autonomic cholinergic nerve terminals, as well as peripheral release of neurotransmitters involved in pain regulation. Thus, their use in neurology has been expanded to include headache and other pain syndromes, as well as hypersecretory disorders. This article highlights some of the common neurologic conditions currently improved by botulinum toxins and reviews the scientific evidence from research studies and clinical experience with these conditions.

Botulinum toxin blocks acetylcholine release at the neuromuscular junction. The drug which was initially found to be useful in the treatment of strabismus has been extremely effective in the treatment of variety of conditions, both cosmetic and noncosmetic. Some of the noncosmetic uses of botulinum toxin applications include treatment of spastic facial dystonias, temporary treatment of idiopathic or thyroid dysfunction-induced upper eyelid retraction, suppression of undesired hyperlacrimation, induction of temporary ptosis by chemodenervation in facial paralysis, and correction of lower eyelid spastic entropion. Additional periocular uses include control of synchronic eyelid and extraocular muscle movements after aberrant regeneration of cranial nerve palsies. Cosmetic effects of botulinum toxin were discovered accidentally during treatments of facial dystonias. Some of the emerging nonperiocular application for the drug includes treatment of hyperhidrosis, migraine, tension-type headaches, and paralytic spasticity. Some of the undesired side effects of periocular applications of botulinum toxin inlcude ecchymosis, rash, hematoma, headache, flu-like symptoms, nausea, dizziness, loss of facial expression, lower eyelid laxity, dermatochalasis, ectropion, epiphora, eyebrow and eyelid ptosis, lagophthalmos, keratitis sicca, and diplopia.

Bilateral idiopathic tonic pupil is characterized by enlarged pupils, poor response to light and accommodation, strong and tonic response to near stimuli, vermiform movements of the iris on slit-lamp examination, and cholinergic supersensitivity. The authors present a case of a 10-year-old girl who was referred with abnormal pupils and complained of headaches. After ophthalmological and neurological examination, she was diagnosed as having migraine and secondary idiopathic bilateral tonic pupils. To the authors' knowledge, this is the first case of a child with bilateral Adie's pupil secondary to migraine to be reported.

A 13-year-old white female with a past medical history of facial acne treated with minocycline presented with headaches, normal visual acuity, bilaterally enlarged blind spots on visual field testing due to bilateral disc edema, and a right fourth nerve palsy. Neuroimaging studies were normal and a lumbar puncture revealed an elevated opening pressure but normal cerebrospinal fluid contents. The diagnosis of pseudotumor cerebri was made and the patient was treated with acetazolamide. The papilledema improved over several weeks and the fourth nerve palsy resolved completely. Fourth nerve palsy is an uncommonly reported nonlocalizing sign in pseudotumor cerebri.
