  • Cranial Nerve Palsy
    Cranial Nerve Palsy What is a cranial nerve? Cranial nerves are nerves that lead directly from the brain to parts of our head, face, and trunk. There are 12 pairs of cranial nerves and some are involved in special senses (sight, smell, hearing, taste, feeling) while others control muscles and glands. Which cranial nerves pertain to the eyes? The second cranial nerve is called the optic nerve. It sends visual information from the eye to the brain. The third cranial nerve is called the oculomotor nerve. It is involved with eye movement, eyelid movement, and the function of the pupil and lens inside the eye. The fourth cranial nerve is called the trochlear nerve and the sixth cranial nerve is called the abducens nerve. They each innervate an eye muscle involved in eye movement. The fifth cranial nerve is called the trigeminal nerve. It provides facial touch sensation (including sensation on the eye). What is a cranial nerve palsy? A palsy is a lack of function of a nerve. A cranial nerve palsy may cause a complete or partial weakness or paralysis of the areas served by the affected nerve. In the case of a cranial nerve that has multiple functions (such as the oculomotor nerve), it is possible for a palsy to affect all of the various functions or only some of the functions of that nerve. What are some causes of a cranial nerve palsy? A cranial nerve palsy can occur due to a variety of causes. It can be congenital (present at birth), traumatic, or due to blood vessel disease (hypertension, diabetes, strokes, aneurysms, etc).

The cases reinforce the principle that any pupil regardless of size should be evalu­ ated for the possibility of pupillotonia.

In this study, we want to assess the effect and mechanism of pupil dilation on IOP in normal subjects. Methods: We prospectively evaluated 32 eyes of 32 patients (age; 61.7 ± 8.2 years) with normal open angles under diurnal IOP. IOP was measured every two hours from 9 AM to 11 PM for one day to establish baseline values and was measured again for one day to assess the differences after dilation. To induce dilation, we administered 2.5% phenylephrine and 1% tropicamide every 5 minutes from 8:30 AM to 8:45 AM and for every two hours from 11 AM to 9 PM to keep the pupil dilated. Diurnal IOP, biometry, Visante OCT, and laser flare photometry were measured before and after dilation. Results: We observed a significant increase in IOP after dilation, 1.85 ± 2.01 mmHg (p = 0.002).

  • Pupil Dilatation with Tropicamide. the Effects on Acuity, Accommodation and Refraction
    Eye (1989) 3, 845-848 Pupil Dilatation with Tropicamide. The Effects on Acuity, Accommodation and Refraction D. M. I. MONTGOMERY! and C. J. MACEWANZ Glasgow and Dundee. Summary The effect of pupil dilatation with tropicamide 1 % on visual acuity and accommo­ dation was assessed in 100 eyes of 52 consecutive patients attending the general ophthalmic outpatient clinic. Snellen visual acuity remained unchanged in 55 eyes and deteriorated by one line in 41 eyes. The remaining four eyes deteriorated by two lines. Tropicamide gave rise to a reduction in the amplitude of accommodation which tended to vary inversely with the age of the patient. However, all patients who wore reading glasses for presbyopia were still able to read when their pupils had been dilated. Many drugs are used routinely in ophthalmic acuity and accommodation in such a practice to dilate the pupil for adequate exam­ population. ination of the ocular fundus. Selection may be based on the speed of onset and duration of action of the drug as well as on the presence Materials and methods and severity of any unwanted effects such as Tropicamide 1 % was used to dilate the pupils cycloplegia.

  • Afe Mydriasis
    Br J Ophthalmol: first published as 10.1136/bjo.54.10.690 on 1 October 1970. Downloaded from Brit. J. Ophthal. (1970) 54, 690 afe mydriasis R. MAPSTONE From the Department of Ophthalmology, (Jniversity of Liverpool, St. Paul's Eye Hospital, Liverpool Routine examination of the fundus requires a dilated pupil. If a cycloplegic drug is used the three major disadvantages are: paralysis of accommodation, an increase in intraocular pressure produced by a mechanism not involving angle-closure (Schimek and Lieberman, I96I; Christensen and Pearce, I963), and a frank attack of acute closed-angle glaucoma. With a sympathomimetic drug only the last complication is of consequence. After the pupil has been dilated it can be either left as such, inviting potential disaster in an eye with a narrow angle, or a parasympathomimetic drug can be instilled, which, if successful in producing miosis, causes a tonic pupil and spasm of accommodation. Neither com- bination is therefore satisfactory. copyright. The purpose of this paper is to describe a mydriatic - miotic combination in which the dangers and disadvantages are reduced to a minimum and to illustrate the properties of the miotic used. Material and methods One drop of thymoxamine (a sympathetic alpha inhibitor: Birmingham and Szolcsfnyi, 1965) was http://bjo.bmj.com/ instilled into the right conjunctival sac of ten subjects. Photographs of both eyes were then taken at a fixed distance, at hourly intervals for 6 hours and again at 24 hours. Each subject received on separate occasions o.

Subsequently, the slides were pro- jected and the horizontal pupil diameter of the eye receiving thymoxamine was expressed as a percentage of the opposite normal eye.
