Definitions

  • This invention relates generally to an Internet system and specifically to an Internet system which presents the user with a plurality of medical screening assays or tests which the end user can self administer.
  • Web sites are relatively easy to create and such has resulted in a rapidly growing number of web sites.
  • the growing number of web sites has resulted in intense competition between web site companies for business and among all web sites to attack traffic to the site.
  • the value of a web site is measured by traffic or the number of "hits" the cite experiences per unit of time.
  • the number of hits per unit of time has importance for at least two reasons. First, as more end users come to the web site the greater the likelihood that they will purchase goods. Second, the web site may generate all or a significant portion of its income from allowing others to advertise on the web site.
  • the value of advertising in any media is related to the number of potential customers being reached.
  • the internet has recently been increasing the efficiency of many industries.
  • At the same time there have been efforts made to decrease the cost of providing medical services. This all is taking place at a time when people seem to have an increased interest in playing a role in and thereby improving the quality of their medical care.
  • the present invention endeavors to improve the efficiency of providing medical services while allowing user patients to play a role in their own care via self-administered tests provided over the internet.
  • a computer generated web site which allows end users to carry out medical screening assays or tests on themselves.
  • the web site includes a plurality of symbols, icons or distinct areas which are each associated with a medical screening assay or test.
  • the program initiates a screening assay or test corresponding to the symbol, icon or area on which the user "clicked. " More specifically, by clicking on an image of an eye the user is presented with one or more tests relating to the eye.
  • the screening assays or tests are generally in one of three groups (1) users watch one or more symbols on a screen for some manner of change, e.g.
  • the user responds to the change and is subsequently provided with information on the user, e.g. glucose level, peripheral vision, etc.; (2) users answer questions and the results are tabulated to provide the user with information on a specific characteristic of the user, e.g. adverse eating habits, probability of having or developing prostrate cancer, etc.; and (3) users react to a stimulus and/or question and the reaction and/or answer is measured against a standard to provide information to the user on criteria, e.g., cognitive ability, or degree of intoxication.
  • criteria e.g., cognitive ability, or degree of intoxication.
  • An aspect of the invention is a computer generated web site which allows users to access a plurality of medical screening assays or tests which can be self administered.
  • An object of the invention is to provide a web site which will attract users.
  • An advantage of the web site of the invention is that it provides users with a number of different medical screening assays and tests accessible at a single site.
  • a feature of the web site is that its assays and tests can provide the user with useful medical information allowing the user to compare personal test results to known standards or to previous results.
  • Another aspect of the invention is that it provides medical information to the user on subjects of specific interest to the user which information is relevant to test results provided to the user.
  • Another feature of the invention is that it provides the user with an opportunity to purchase drugs, nutriceuticals, medical devices and medical books specific to the user's interest.
  • the Internet provides an important tool for consolidating and presenting these "software only" diagnostic tests which require nothing more than a computer at the point-of-use.
  • the present invention encompasses such and also covers medical tests which are facilitated by the Internet but require additional devices, e.g. ear phones or blood pressure gauge.
  • URLs Uniform Resource Locators
  • This reduces delay associated with accessing the screening test modules.
  • this consolidation simplifies the process of tracking an individual's interest in specific tests as well as the appeal of a given test to multiple users.
  • By tracking test utilization by users it is possible to market specific products and services to persons most likely to buy those products and services. For example, eye glasses to individuals exploring the site for vision-based testing or diabetes products to persons running the glucose-screening module.
  • screening modules are by no means limited to executable code producing an animated graphics and sound.
  • a screening module could represent a list of questions presented to the user. After the questions are answered, an interpretation in presented. For example, a list of questions designed to determine if the user is depressed, an alcoholic or suffering from benign prostatic hypertrophy.
  • the site includes tests which are approved by the appropriate governmental agency (e.g. the FDA in the U.S.) and in a particularly preferred embodiment all of the tests are governmentally (e.g. FDA) approved tests.
  • screening procedures could be implemented in a variety of ways including, running code remote to the server as well as, for example, Java applets which would be transparently downloaded by the user and run local to the user's computer.
  • the web site used in the invention can be designed in any desired manner.
  • the user is first presented with a screen briefly describing the web site, the types of tests provided and appropriate disclaimers.
  • the initial screen may request user identification information and ask the user if the disclaimers have been read and understood.
  • the user is provided access to a subsequent page.
  • This page preferably obtains some basic information from the user such as age, sex, race, weight, height, current or prior medical condition including drugs currently used in treatment.
  • the questions are preferably designed in a manner similar to that which would be completed by a patient on first visiting a caregiver, e.g. doctor, dentist, hospital, etc.
  • the information obtained is stored in a server and used as needed for that particular user, e.g. to compare the users test results with other users with similar relevant characteristics.
  • the user may be provided with an identification number. Such would allow the user to use a single test multiple times and/or use other tests without resending data.
  • Systems of the type taught in U.S. Patent 5,960,411 issued September 28, 1999 are exemplary of this particular web site construction.
  • the user is preferably provided access to a screen which shows a plurality of possible tests which the user may access and self administer.
  • the different tests may be represented on the screen by any word, group of words, figure, or combination thereof.
  • a test for color blindness may be represented by the phrase "color blindness test" alone or with colored lines, with or without an image of an eye.
  • the symbols representing the tests may be randomly presented or presented in any desired order e.g. alphabetically, by class (e.g. medical or cognitive) or by the type of testing system used (e.g. question and answer or stimulus response).
  • the tests available to users can be designed to provide very general information about the user or provide specific information about the condition of the user or a specific organ or system of the user.
  • An important advantage of the invention is that there are large numbers of tests available for use which could provide valuable information to users if made readily accessible. However, it is generally too expensive to extensively commercialize any individual test. Thus, many potentially valuable tests remain both unknown and unused. By concentrating large numbers of tests together on a single web site, the expense of advertising can be diluted many times. Further, users of the tests provide further traffic to the web site by giving others the web site address when they are pleased with the results obtained or believe it might be of interest and/or value to others.
  • the web site of the invention can be designed to include condensed versions of tests which are more fully available elsewhere.
  • Tests provided on the web site of the invention are preferably designed such that no equipment or device beyond the user's screen and speakers are required. More preferably, the test can be carried out with only the user's screen, i.e. no need for speakers. However, it is understood that tests provided on the web site of the invention may be used with other devices or equipment. Simple examples of devices which may assist in carrying out other tests include all types of measuring devices e.g. a watch, an attachable probe, a thermometer, a scale, a flexible length measuring device, etc.
  • earphones and eyeglasses could also be used to facilitate some vision and hearing tests of the invention.
  • Another important advantage of the invention is that the web site will encourage subjects to screen multiple physical and/or physiological characteristics beyond those which may have originally attracted them to the site. For example, users coming to the site to test their vision might be surprised to find that a visual display can be used to determine glucose level in an individual. Users coming to the site to take a cognitive test might later return to the site to test their response time which could be related to the users blood alcohol level and as such the ability of the user to safely operate a motor vehicle.
  • Medical tests included for use as part of the web site of the invention may be administered by the user, on the user, to provide information about the user - and is preferred thereby making the web site and its tests self contained, i.e. not requiring other people or devices.
  • the tests on the web site of the invention might be carried out by one person on another, by one person on several others or by one person on one or more objects.
  • the medical tests could greatly facilitate at home health care which could be carried out by the patient thereby reducing health care costs.
  • a user/patient could self-administer a test, and the results could be sent and/or accessed electronically to a health professional.
  • Tests could also be administered by teachers in schools to one or more students. Such tests would, for example, make it possible for teachers to quickly determine if a student had a learning disability.
  • Medical tests could also be carried out by the user on an object, e.g. a body fluid.
  • the user could be provided with a means to extract blood and an assay device to contact with the blood after which results created by the contact are provided back to a central location, an analysis carried out and results provided to a user.
  • the main objective of the web site of the invention is not, necessarily, to sell goods.
  • goods and advertising could be added.
  • any medical test on the web site could be used to reference the user to a more complete version of the medical test which might be sold over the Internet.
  • users found to have the characteristics of a certain disease could be referenced to a particular hospital, doctor or other healthcare organization or medical professional.
  • Drugs, vitamins or nutriceuticals that could be used to treat or ameliorate a condition could be advertised to the user while meeting appropriate regulatory requirements.
  • the tests on the web site of the invention could be readily used in a medical setting.
  • the test may provide nothing more than a probability index as to whether the user had a particular disease or medical problem.
  • tests with FDA approval could also be included thereby giving users a means of accurately screening themselves for various problems.
  • medical costs could be dramatically reduced and the accessibility of medical care significantly expanded.
  • the present invention may feature any number of sites that offer screening for physical and/or physiological visual acuity. Such sites may include, but are not limited to, screens for the following: visual acuity, e.g., U.S. Pat. Nos. 4,998,820 and 5,436,681; ability to distinguish colors, e.g., U.S. Pat No.
  • dyslexia e.g., U.S. Pat. Nos. 4,706,686 and 5,420,653

  • Specific exemplary medical screening tests are briefly described below.
  • a number of different tests can be used in the present invention to determine visual acuity, e.g., myopia (nearsightedness), hyperopia (farsightedness), presbyopia (age related inability to focus at near task), astigmatism and the like.
  • Exemplary methods for computer- based screening of visual acuity include tests that screen for a single deviation (e.g., a screen only for myopia) and tests that screen for multiple tests simultaneously (e.g., hyperopia and myopia).
  • U.S. Pat. No. 5,436,681 describes a method for simultaneously screening myopia and hyperopia.
  • This patent provides a vision screening apparatus and screening method that includes a myopic screening test image and a hyperopic screening test image.
  • Each screening test image includes a test letter member superimposed on a colored background member that, in combination, forms the myopic screening test image portion and the hyperopic screening test image portion.
  • the myopic test image is formed by a test image member, such as a letter, superimposed on a red colored background.
  • the hyperopic screening test image is formed by a test image, such as a letter, superimposed on a green colored background.
  • the method includes determining the patient's visual acuity of the displayed myopic and hyperopic test images, and then determining which, if any, of the conditions exists.
  • Good visual acuity of the myopic test image indicates myopia in an individual, while good visual acuity of the hyperopic test image indicates hyperopia.
  • Good visual acuity of both test images indicates no condition.
  • Use of the apparatus at less than one meter distance results in a method of screening for an inability to focus on a near task (presbyopia).
  • U.S. Pat. No. 4,998,820 provides an optical instrument for use in conducting optometric examinations which generates an alphanumeric type display simulating the optical features of displays provided by video display terminals.

  • the computer screen can degrade the image quality of the characters by transforming the light elements into Gaussian type spatial profiles typical of the pixels generated by VDTs, thus further testing the ability of an individual to distinguish the form of letters and/or numbers.
  • Color Vision Screening The present invention can also can include methods for screening color blind individuals. These tests may optionally screen for visual acuity simultaneously.
  • U.S. Pat No. 5,801,809 provides a method for testing color perception at the same time that visual acuity is measured.
  • the computer generated eye chart with color vision screening includes a chart which displays objects of progressively smaller sizes with the larger sized objects being displayed in color to measure color perception.

  • Scotopic sensitivity syndrome (commonly referred to as being "night blind”) can be initially screened using computer generated visuals.
  • U.S. Pat. No. 5,067,806 describes a method for determining using a visual pattern and the presence or absence of a colored filter. The filters are chosen to reflect the spectral sensitivity of the cones and their combinations. Two different filtered images with the same test patterns are shown to the subject, and the subject determines which is clearer. The image chosen is kept and compared to a next figure with a different filter, and so forth. The last figure always given is the one without a filter. The patient is then asked if the filtered image is clearer than the unfiltered. The patient who sees a filtered image better than the unfiltered is referred for further testing by an optometrist familiar with this syndrome. If the unfiltered image is clearer the patient does not have scotopic sensitivity syndrome.
  • U.S. Pat. No. 5,713,353 provides a visual method for determining blood glucose levels by providing a changing light pattern which changes in regard to one or several parameters defining its luminance, color, rate of flicker, spatial contrast, detail content, speed or otherwise provided that the change gradually stimulates one retinal system more than another retinal system.
  • the subjective visual effect indicates a specific ratio of stimulation of the two retinal systems, for example the point of balanced stimulation of the two systems.
  • the patient actuates a mechanism which takes note of the current light pattern parameter values, allowing the device to relate such parameter values with a corresponding blood glucose level using predetermined calibration data.
  • U.S. Pat. Nos. 5,946,075 and 5,061,059 provide a method for detecting the presence of glaucoma and diabetes-associated eye disease in a human eye.
  • a test subject is presented with a fixation target positioned on a computer screen The test subject focuses a test eye on the fixation target and positions the test eye a sufficient separation distance from the fixation target and aligns the test eye relative to said fixation target so that the test subject's central and peripheral visual health can be tested. Additional marks are presented on the computer screen for detection by the test subject using the peripheral vision of the test eye.
  • the additional marks are primarily the same level of black-white contrast as the computer screen but different in hue to create color contrast symbols, and are presented within the field of vision of an eye not afflicted with the disease for which testing is being conducted. The potential presence of eye disease is detected if the additional marks are not visible to the test subject.
  • each light comprises a mixture of two different wavelength lights (e.g., different colored lights).
  • One of the lights is a fixed reference mixture, while the mixture of the other light is varied until the patient observes a match between the two lights in terms of hue, brightness and saturation.
  • the luminance levels of the test light wavelength components for providing the match and the proportionate levels of the standard and test light components are then determined.
  • the shorter wavelength light of the test light mixture is substituted with a new wavelength light and the new mixture varied again until the patient observes a match as before.
  • the luminance levels of the light components of the new test light are then determined and another proportion obtained representative of the proportionate levels thereof.
  • the first and second proportions are then compared to respective proportions of a standardized group. Deviations between the proportions of the patient and the standardized group indicate the existence of a cataract and/or the degree of a cataract precursor formation.
