Ernest Maddox
Ernest Edmund Maddox (1863 – 4 November 1933) was a British surgeon and ophthalmologist. He was a specialist in abnormal binocular vision and phorias (heterophoria in particular). He made advances in optical treatments and invented several devices to better investigate eye conditions, including Maddox rod, double prism Maddox, red glass Maddox, Maddox cross and Maddox wing. As a keen amateur astronomer he also invented the starfinder, a device to home in on stars and constellations. Life He was born in Shipton-under-Wychwood, the son of J. F. Maddox. He was educated at Mill Hill School then studied medicine at the University of Edinburgh, graduating with an MB CM in 1882 and gaining his doctorate (MD) in 1889. In 1894 he was elected a fellow of the Royal College of Surgeons of Edinburgh. He worked for a decade in Edinburgh alongside Argyll Robertson pupil, Dr Argyll Robertson. In the 1890s he was living at 7 Manor Place in Edinburgh's West End. His neighbour was the lighthou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heterophoria
Heterophoria is an eye condition in which the directions that the eyes are pointing at rest position, when ''not'' performing binocular fusion, are not the same as each other, or, "not straight". This condition can be esophoria, where the eyes tend to cross inward in the absence of fusion; exophoria, in which they diverge; or hyperphoria, in which one eye points up or down relative to the other. Phorias are known as 'latent squint' because the tendency of the eyes to deviate is kept latent by fusion. A person with two normal eyes has single vision (usually) because of the combined use of the sensory and motor systems. The motor system acts to point both eyes at the target of interest; any offset is detected visually (and the motor system corrects it). Heterophoria only occurs during dissociation of the left eye and right eye, when fusion of the eyes is absent. If you cover one eye (e.g. with your hand) you remove the sensory information about the eye's position in the orbit. Wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People Educated At Mill Hill School
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Ophthalmology
Ophthalmology ( ) is a surgical subspecialty within medicine that deals with the diagnosis and treatment of eye disorders. An ophthalmologist is a physician who undergoes subspecialty training in medical and surgical eye care. Following a medical degree, a doctor specialising in ophthalmology must pursue additional postgraduate residency training specific to that field. This may include a one-year integrated internship that involves more general medical training in other fields such as internal medicine or general surgery. Following residency, additional specialty training (or fellowship) may be sought in a particular aspect of eye pathology. Ophthalmologists prescribe medications to treat eye diseases, implement laser therapy, and perform surgery when needed. Ophthalmologists provide both primary and specialty eye care - medical and surgical. Most ophthalmologists participate in academic research on eye diseases at some point in their training and many include research as part ...

British Medical Association
The British Medical Association (BMA) is a registered trade union for doctors in the United Kingdom. The association does not regulate or certify doctors, a responsibility which lies with the General Medical Council. The association's headquarters are in Tavistock Square, London and it has national offices in Cardiff, Belfast, and Edinburgh, a European office in Brussels and a number of offices in English regions.

Maddox Rod
The Maddox rod test can be used to subjectively detect and measure a latent, manifest, horizontal or vertical strabismus for near and distance. The test is based on the principle of diplopic projection. Dissociation of the deviation is brought about by presenting a red line image to one eye and a white light to the other, while prisms are used to superimpose these and effectively measure the angle of deviation (horizontal and vertical). The strength of the prism is increased until the streak of the light passes through the centre of the prism, as the strength of the prism indicates the amount of deviation present. The Maddox rod is a handheld instrument composed of red parallel plano convex cylinder lens, which refracts light rays so that a point source of light is seen as a line or streak of light. Due to the optical properties, the streak of light is seen perpendicular to the axis of the cylinder. Equipment required in Maddox rod testing * Maddox rod * Light source at near ...
