CASE REPORT A 19 year-old boy who developed a right Horner's syndrome after a bilateral sympathectomy as a treatment for palmoplantar hyperhidrosis. DISCUSSION Horner's syndrome is defined by the occurrence of miosis, ptosis and enophthalmos as a result of involvement of sympathetic innervation. This is quite rare, but identification is very important because it may also be an ominous sign se...

Three patients with paralysed horizontal gaze are presented. Involuntary use of convergence to assist horizontal gaze was noted as a late feature. All patients showed (1) unilateral or bilateral horizontal gaze palsy (two patients had one and a half syndrome, the other had bilateral nuclear sixth nerve palsies), (2) adduction of both eyes on attempted gaze into the paralysed field, (3) miosis w...

CLINICAL CASE A 42-year-old man presented with ptosis and miosis in his left eye and a history of headache over the last 20 days. An angioresonance showed dissection of internal carotid artery. DISCUSSION "Painful Horner's Syndrome" is considered to be a medical emergency due possible onset of an internal carotid artery dissection. We consider that awareness of neuro-ophthalmologic emergencie...

Spasm of the near reflex, as first described by Cogan in 1955, is a triad of intermittent convergent strabismus, accommodative spasm, and pupillary miosis. The accommodative spasm induces pseudo-myopia that is usually accompanied by visual blurring. It is a functional disorder that has been attributed to hysteria, although it can have an organic etiology. Definitive treatment remains problemati...

Anterior uveitis clinical signs include epiphora, conjunctival erythema, reduced intra-ocular pressure, corneal edema, miosis and ocular discomfort, among others (Gelatt, 1999). It is presented as a bilateral entity when occurring as a consequence of a systemic disease (Slatter, 1990), which it is commonly associated (Whitaker et al., 1998). Among the most common diseases in bovine are neonatal...

In healthy volunteers pilocarpine in an oily solution had a greater degree and duration of effect on the pupil than the same amount of drug given in aqueous solution. Blue- and brown-eyed subjects had similar degrees of miosis, but the time taken to reach peak effects was longer with the latter. It can be concluded that eye drops made with an oily solvent may provide an improvement in the treat...

DOCUMENT RESUME

A double-blind study was performed on 64 patients to assess the effect of preoperative indomethacin in comparison with a placebo in preventing surgically induced miosis during extracapsular cataract extraction. One drop of indomethacin or placebo was instilled at 7.00 p.m. and at 9.00 p.m. the night before surgery and 2 hours, 1 hour, and 15 minutes preoperatively. The pupil diameter was record...

The effect of an antiprostaglandin, piroxicam, in preventing surgically induced miosis is studied. Patients undergoing extracapsular cataract surgery were randomly divided into the piroxicam and placebo groups. Intra-operative measurements of the pupillary diameters were performed. The stages of procedure at which they were measured were at the beginning of operation (Stage 1), after anterior c...

Children in a tribe of sea-gypsies from South-East Asia have been found to have superior underwater vision compared to European children. In this study, we show that the improved underwater vision of these Moken children is not due to better contrast sensitivity in general. We also show that European children can achieve the same underwater acuity as the Moken children. After 1 month of underwa...
