-iminoethyl)-lysine (4 mg/kg), was injected intraperitoneally immediately after CLP to produce the CLP + L-N6-(1-iminoethyl)-lysine group to exclude the influence of depressed hemodynamics on neurologic impairment.It was found that administration of AM 281 could prevent the hemodynamic changes induced by sepsis. Reflex responses, including the pinna, corneal, paw or tail flexion, and righting reflexes, and the escape response significantly decreased in the CLP and CLP + L-N6-(1-iminoethyl)-lysine groups (...) at 48 hrs after the surgery. In contrast, no changes in these reflex responses were found between the CLP + AM 281 and control and sham groups. In addition, no effects of the administration of AM 281 on neurologic function and mortality rate in the control group were found. Tissue caspase-3 levels were elevated at 48 hrs after CLP in the CLP alone group (means +/- sd: control, 3.9 +/- 0.4; sham, 4.2 +/- 0.4; CLP, 7.1 +/- 1.0 [p < .01]; CLP + AM 281, 4.0 +/- 0.5 densitometric units).

after resuscitation from CA and treated with TIMH.None of six patients without pupillary reactivity, six without cornealreflexes on day 3, or eight with myoclonus status epilepticus recovered awareness. Two of 14 patients with motor responses no better than extension at day 3 recovered motor responses only after 6 days post-arrest (one at 5 and one at 6 days post-rewarming) and regained awareness.Loss of motor responses better than extension on day 3 was not prognostically reliable after (...) therapeutic induced mild hypothermia for comatose cardiac arrest survivors. None of the patients who lost pupillary or cornealreflexes on day 3 or developed myoclonus status epilepticus recovered awareness.

palpebral surgery, and crossbreeding. Images were obtained with a digital camera, 30 cm from the frontal plane at pupil height, with the individual in a primary position and the eye trained on the camera lens. Images were transferred to computer and processed by the Scion Image program. Measurements were made of distance between medial canthi, distance between pupils (IPD), superior eyelid crease position, distance between the superior lid margin and cornealreflexes (MRD), horizontal width, height
retrospectively reviewed and the clinical characteristics and postoperative surgical results of these patients were analysed. This study was a retrospective, non-randomised, interventional case series and the main outcome measures were margin reflex distance, eyelid contour and corneal status.Seven patients were recruited (one male and six female). The mean age at the time of operation was 29.6 (range 15-62) years. Two patients had unilateral ptosis and five patients had bilateral ptosis. The mean follow-up (...) period was 22.7 (range 1-61) months. Satisfactory lid height was achieved in all patients. Although corneal erosions were detected in five patients 1 month after surgery, these findings eventually resolved in three patients 2 months later, after the use of artificial tear eyedrops and ointments.The frontalis sling operation using silicone rod can safely and effectively correct ptosis in chronic progressive external ophthalmoplegia patients without serious corneal complications.
Abnormal foveal avascular zone in nanophthalmos. To evaluate the foveas of nanophthalmic patients.Retrospective observational case series.Four nanophthalmic patients examined between April 2005 and April 2006 were included. Visual acuity (VA), refractive correction, axial length, corneal diameter, presence or lack of foveal light reflex, as well as fluorescein angiograms (FAs), and optical coherence tomography (OCT) scans of the maculae were evaluated.None of the eight eyes had a foveal light (...) reflex, corresponding to lack of a normal foveal pit on OCT. Fluorescein angiography showed no normal foveal avascular zones; all were either completely absent or small and rudimentary.Nanophthalmic patients rarely have best-corrected visual acuity (BCVA) better than 20/40 at any point in their lives, even with an absence of known complications, such as uveal effusion or glaucoma. In many patients, this visual deficiency may correspond to an absent or rudimentary foveal avascular zone and lack
to evaluate the technique.Prospective noncomparative surgical trial in which preoperative and postoperative symptoms, margin reflex distances, vertical palpebral aperture (PA), lagophthalmos, and corneal findings were recorded. The data were analyzed at 6 months after surgery using the Wilcoxon sign-rank test for nonparametric data.Fourteen consecutive adult patients (15 eyelids) with chronic lagophthalmos and paralytic ectropion.Patients underwent aug-LTS-T. This consisted of a long strip (10-15 mm (...) ) that is attached to the outer temporal orbital rim, at a point higher than a conventional LTS. It included removal of a small part of the upper eyelid anterior lamella laterally to pass the long strip up high enough.Improvement of symptoms, reduction of lower margin reflex distance, lagophthalmos, and improvement of corneal signs.Minimum follow-up was 6 months. There was a significant reduction in PA (P = 0.005) and lagophthalmos (P = 0.0002) with improvement of corneal signs (14 of 15 eyelids = 93%). Surgery
institution.Chart review of patients who underwent super maximum levator resection with or without superior tarsectomy. Data regarding eyelid position, surgical outcome, and postoperative complications were evaluated.Margin reflex distance-1 (distance [mm] between corneal light reflex and upper eyelid margin), bilateral eyelid symmetry, and postoperative complications.A statistically significant improvement in ptosis correction was demonstrated when integrating the superior tarsectomy with the super maximum (...) levator resection (P = 0.029). In addition, the superior tarsectomy significantly decreased the incidence of undercorrection (margin reflex distance-1 values less than 2.0 mm) compared with the super-maximum levator resection alone (12.5% vs. 70%; P = 0.023). Improved postoperative eyelid symmetry within 1.0 and 1.5 mm was demonstrated in cases treated by the superior tarsectomy. Postoperative complications were similar in both treatments.The super maximum levator resection combined with superior
Positive angle kappa: a sign of albinism in patients with congenital nystagmus. To determine whether the association of positive angle kappa and congenital nystagmus is a distinguishing feature of albinism.Observational case series.Prospective examination of the location of the corneal light reflex in patients with albinism and idiopathic congenital nystagmus.A positive angle kappa in at least one eye was noted in 20/21 (95%) patients with albinism versus 4/12 (33%) patients with congenital
authors identified four class I studies, three class II studies, and five class III studies on clinical findings and circumstances. The indicators of poor outcome after CPR are absent pupillary light response or cornealreflexes, and extensor or no motor response to pain after 3 days of observation (level A), and myoclonus status epilepticus (level B). Prognosis cannot be based on circumstances of CPR (level B) or elevated body temperature (level C). The authors identified one class I, one class II (...) (level B). Ten class IV studies on brain monitoring and neuroimaging did not provide data to support or refute usefulness in prognostication (level U).Pupillary light response, cornealreflexes, motor responses to pain, myoclonus status epilepticus, serum neuron-specific enolase, and somatosensory evoked potential studies can reliably assist in accurately predicting poor outcome in comatose patients after cardiopulmonary resuscitation for cardiac arrest.
. Abnormalities of any of the answers suggest macular pathology. Patients can use the grid at home and test themselves (remind them to do one eye at a time) [ ] . Examination of the macula Ophthalmoscopy - the macula is visible as a dark circular patch between the vascular arches, the fovea being about 1 disc diameter lateral to the disc itself. The foveola is usually seen as a bright pinpoint yellow reflex at the centre of the macula. If you ask the patient to look directly at the light, the macula (...) . The optimal management for these conditions is discontinuation of the medication where possible and observation in the ophthalmology outpatient clinic. Many resolve in time. Chloroquine and hydroxychloroquine - these both have the potential for retinotoxicity and may also result in corneal deposits. The retinopathy is related to the total cumulative dose and is more marked with chloroquine. Patients present with decreased vision (which may be severe in end-stage chloroquine maculopathy - less than 6/60

Surgical implantation of artificial valves to control the release of intraocular fluid is often required. Corneal keloids may require surgical removal of the scar tissue, or radiation therapy. Corneal transplantation is difficult because of problems in administering the required intensive postoperative care. Sometimes surgical correction of is required.

If the mother is a carrier, there is a 50% chance of any son being affected and any daughter being a carrier. Did you
deposits in the retinal vessels remain when blood pressure is reduced; however, retinopathy resolves when blood pressure is treated. Changes develop within 48 hours of blood pressure rising and resolve in 2-10 weeks of it being lowered. Complications of hypertensive retinopathy include optic neuropathy and central vein or artery occlusions. Hyperthyroidism may cause proptosis, which may be the first sign of the condition.

with 'panda eyes' from a base of skull fracture.) Conjunctiva : look for haemorrhage and lacerations (small lacerations can be subtle - they may show up on staining with fluorescein) - these can indicate an open globe injury. Cornea : lacerations may be small and missed: Perform a Seidel's test first (to assess for leakage from the cornea - see 'Techniques', below) and then assess for corneal abrasion with dilute fluorescein. Anterior chamber : look for hyphaema (the patient needs to be upright to see (...) level). Iris and pupils : check shape, size, reactive and equal. Pupil or iris damage is a serious sign. Fundus : loss of red reflex could be due to opacification from blood in the vitreous or a large retinal detachment. IOP : should also be assessed - if possible - unless you suspect an open globe injury. Perform a functional examination: Movement of the eyes (ask about diplopia before and during examination). Pupil reactions test visual fields . Test for relative afferent pupillary defect
. The pterygoids may jut the jaw forwards. Many neurologists omit the cornealreflex unless a sensory deficit is found, especially in the ophthalmic division, or if there is a lesion of another cranial nerve. Take a clean piece of cotton wool and ask the patient to look away from the side being tested. Gently touch the cornea with the cotton wool and the patient will blink. This requires the sensation of V but also the motor of VII. There may be a positive jaw jerk reflex in spasticity. This is difficult (...) pathway) and the oculomotor nerve (efferent pathway), as the response is dependent upon appreciation of light and the motor response of the muscles of the iris. There is also a consensual response in that the contralateral pupil will also respond but less markedly. Then use the ophthalmoscope to examine the eye. First hold it away from the patient and look through it at the eye. There should be an orange reflex from light reflected from the retina. This means that the lens is clear
is held about an arm's length away from the patient. Look through the ophthalmoscope and turn the dial until you see the red reflex. This can be attenuated by any opacity between the cornea and the fundus: a corneal opacity is visible externally and a vitreous opacity may be mobile. The red reflex is part of the routine neonatal check. Use a direct ophthalmoscope in a dimly lit room and hold your ophthalmoscope about 2/3 of an arm's length away from the baby. If the baby is screwing their eyes shut (...) passing through the shaft of light) and for flare (slight cloudiness), suggestive of anterior . Pupils Look at their relative size - if you suspect anisocoria (different-sized pupils), stand back from the patient, darken the room and look through the ophthalmoscope. You can elicit the red reflex in both eyes and compare the size of these directly rather than shifting from one to the other close up. Look for change in shape (typically oval in acute angle-closure glaucoma, asymmetry in a penetrating

Superficial keratitis may occur in response to UV injury (photokeratitis), or to chemical injury (eg, from tear gas). Corneal FBs usually cause marked irritation, redness and watering, often with pain and a repeated blink reflex. Patients are usually very good at localising the FB [ ] .
