Intracerebroventricular (ICV) injection of carbachol into the third ventricle of conscious rabbits increased pupil size and intraocular pressure (IOP). A significant increase of pupil size by 0.6-1.3 mm for 60-90 min was observed with the dose of 1 microgram and an increase of IOP by 1.1-1.9 mmHg for 15-60 min was observed with doses over 10 ng. These responses were due to central cholinergic s...
PURPOSE The perceived and reported pain of patients receiving photorefractive keratectomy (PRK) widely varies. We assessed the potential role of the subbasal nerve plexus density as a predictor of postoperative pain level. Consecutive patients scheduled to undergo PRK at the Refractive Surgery Clinic of Farabi Eye Hospital, Tehran, were approached. METHODS Forty-nine myopic left eyes from 49 ...
Familial amyloid polyneuropathy (FAP) type IV (FINNISH) is a rare clinical entity with challenging neuropathy and cosmetic deficits. Amyloidosis can affect peripheral sensory, motor, or autonomic nerves. Nerve lesions are induced by deposits of amyloid fibrils and treatment approaches for neuropathy are challenging. Involvement of cranial nerves and atrophy in facial muscles is a real concern i...
Moebius syndrome (MS) is a congenital syndrome characterized by unilateral or bilateral aplasia of the VI and VII cranial nerves, with consequent convergent strabismus and bilateral peripheral facial paralysis. This syndrome might be associated with diurnal excessive sleepiness and muscular hypotony, mimetizing in this manner, narcolepsy. The diagnostic criteria for narcolepsy depend on the pre...
Microphthalmia with limb anomalies (MLA) is a rare autosomal-recessive disorder, presenting with anophthalmia or microphthalmia and hand and/or foot malformation. We mapped the MLA locus to 14q24 and successfully identified three homozygous (one nonsense and two splice site) mutations in the SPARC (secreted protein acidic and rich in cysteine)-related modular calcium binding 1 (SMOC1) in three ...
We report that eight heterozygous missense mutations in TUBB3, encoding the neuron-specific beta-tubulin isotype III, result in a spectrum of human nervous system disorders that we now call the TUBB3 syndromes. Each mutation causes the ocular motility disorder CFEOM3, whereas some also result in intellectual and behavioral impairments, facial paralysis, and/or later-onset axonal sensorimotor po...
Certain ocular diseases such as glaucoma cause an increase in the internal pressure of the eye, damaging nerves. An implantable pressure sensor would give patients the ability to monitor their own intraocular pressure and then consult a physician if necessary. One device to do this has been developed using a microscopic Fabry-Perot interferometer with the plates implanted between the intraocula...
This paper describes two patients with squamous cell carcinoma (SCC) of the periocular and periorbital skin who presented with trigeminal neuralgia. Both patients had previous cutaneous SCC of the scalp treated successfully with surgical resection but later presented with neuro-ophthalmic findings suggesting perineural invasion (PNI) of SCC. PNI of SCC in the periocular skin or orbit can lead t...
Corneal nerves are mainly derived from the ophthalmic branch of the trigeminal ganglion (TG). Corneal neuropathy contributes to epithelial degenerative changes in diabetic keratopathy. Efficient drug delivery to TG may be beneficial for the treatment of diabetic keratopathy. This article described intranasal delivery of nanomicelle curcumin to correct pathophysiological conditions in TG to prom...
ANEURYSMS occur more frequently within the cranium than elsewhere in the body, and most-75 to 85 per cent. according to Walsh (1964)-are situated on the anterior part of the circle of Willis. In this region they are closely related to the primary visual pathways and motor nerves to the eye. Extra-ocular muscle palsies are well recognized by ophthalmologists as indicative of such lesions, partic...
