![]() – Adequate consultation with neuroradiology is highly recommended. Exclude other associated intracranial abnormalities such as demyelinating plaques.MRI with fat suppression and gadolinium of the orbits and brain is considered the minimum work-up.If there is no explanation from the ophthalmic examination, neuroimaging is mandatory. An RAPD infers objective evidence of pathology of the anterior visual pathways.– Advanced objective measurements with pupillometry devices but less often used clinically – Subjective impression of brightness differential can be asked of the patient – Objective measurement using a neutral density filter to quantitate – Subjective grading by the examiner often ranging from “trace” or ±, through +1 to +4 When an RAPD is present the pupil on the affected side will dilate more (pupillary escape).The light is now directed at the left eye (swinging flashlight test), and both the direct and consensual pupillary reflexes are observed.The consensual contralateral pupillary response in the left eye is observed (pupil should also constrict).The direct ipsilateral pupillary response is observed (pupil should constrict).However, if one eye has a problem with detecting light (usually from a problem with the retina or optic nerve), there will be less constriction when light is shown on that eye. Of course, normally, if you flash light in one eye, both pupils will constrict. A bight light source is directed at the right eye The Marcus Gunn pupil can be detected by swinging a flashlight between both eyes.Patient asked to distance fixate preferably in dim ambient light conditions.– Pain associated with eye movement in optic neuritis Unilateral loss of color perception or desaturation of color.Nonarteritic anterior ischemic optic neuropathy (NAION).Demyelinating disease (multiple sclerosis).Extensive retinal involvement from multiple causes.Optic neuropathy of any etiology if unilateral or asymmetric.Dense, extensive anterior chamber or vitreous hemorrhage produce RAPD – Media opacity within the eye such as cataract will not cause an RAPD. Pathology resulting in loss of function within the afferent visual pathway, which may include the retina, optic nerve head, optic nerve, chiasm, and the anterior optic tract proximal to the lateral geniculate body.Decreased amount of light transmitted along one side of the anterior visual pathway.Mitochondrial disease such as Leber’s hereditary optic neuropathy may present asymmetrically or with one eye involved prior to the contralateral eye.Most inherited retinal conditions are less likely to cause an RAPD unless there exists considerable asymmetry of involvement of one eye compared with the other.Relates to the prevalence of afferent visual system disease in the particular population Meningiomas and pituitary tumors occur or increase in size with increased frequency during pregnancy resulting in RAPD Previously known as the Marcus–Gunn pupillary phenomenon.Ĭataract (commonly seen in geriatric patients) does not cause a relative afferent pupillary defect (RAPD).Ībsolute indication of pathology involving the afferent visual pathway especially in preverbal patients.It is a sign that can be seen in a large variety of disease entities. Different response of one pupil compared with the contralateral pupil when stimulated by a bright light.I simply had to act to find emergency funding in this time of crisis. “For too long, I’ve been calling on the Government to ease the burden on families by providing free school meals. “No child should go hungry, but a tragic symptom of the cost-of-living crisis means that sadly, far too many children are,” Mr Khan said in a statement. On Monday, London Mayor Sadiq Khan announced one-year of funding for free school meals for all primary school children in the capital. “We have also worked with our Parent Forum to reduce the cost of our school uniform, ensuring it is as competitively priced as possible whilst still maintaining our high expectations,” Mr Smith added. The trust is also offering parents a uniform exchange where they can trade items their children have grown out of for better-suited sizes. “The uptake and popularity of both these initiatives is fantastic, and our students have given lots of positive praise to our catering teams for their efforts in ensuring all are catered for.” “Additionally, we offer a free breakfast for all our students at the academies every day from 8am. Gary Smith, chief executive at the trust, said: “We hope we can support families in reducing their school lunch bill, as well as providing all students with a hot, nutritious meal.

The academies, which have a total of 1665 students, also offer a free breakfast every morning at 8am. Around 40 per cent of pupils at the two schools are eligible for free meals, and the move is designed to reduce families’ lunch costs by up to 40 per cent.
