A human eye is a complicated optical system in which an eye lens (transparent, double-convex biological lens, providing for the dynamics of optics) is its light-conducting and light-refringent part. The more transparent an eye lens is, the better it fulfils its functions. But eventually an eye lens loses its transparence, it will partially or fully mist up which will lead to the lowering of the light transition to the retina. This is an age-related cataract, the symptom of which is the feeling as if surrounding objects were viewed through dim glass, the patient practically almost loses acuity of vision at night time. The dimness of the eye lens can be also be caused by traumatic cataract, provoked by the influence of damaging factors – mechanical (including contusive), chemical, thermal, radiation etc.
Nowadays the cataract is one of the most wide-spread eye diseases. Modern methods of detection of the level of the eye dimness (cataract) with the help of electronic equipment are rather accurate, but final diagnosis is made by an ophthalmologist on the basis of the subjective evaluation of the instrument readings
According to the requirements of the Ministry of Public Health of the RF, the time of reception of one patient by an ophthalmologist should not exceed 14 minutes. During this period of time it is not always possible to get anamnesis, detect the pathology of an eye bulb, explain to the patient the necessity and tactics of treatment, help make the right choice. In that case computer technologies help the doctor. A system of preliminary patients’ testing, worked out at MEPhI Department of computer medical systems, will help doctors make a right and quick diagnosis and detect methods of treatment.
The invention of young scientists from MEPhI Department № 46 “Computer medical systems” is about to help Russian doctors. A 5th year student Kseniya Kirillovikh has worked out a system of patient’s testing which will allow gather preliminary data about them in the Internet, raising the efficiency of the detection of the cataract symptoms. QtCreator development framework and SQLite database have been used for the creation of the system. The necessary data for the testing has been provided by the Federal Medical and Biological Agency of Russia (FMBA).
According to the researcher’s words, the testing systems consists of 23 questions: general (sex, gender), and those related to the patients’ lifestyle and subjective estimation of the state of their visual functions made by themselves. The results of the tests are recommendations about possible presence or absence of the cataract and options of dim eye’s lens replacement for an artificial one.
The program comprises a database allowing store answers and conclusions by testing results.
