Compared with prior art, the beneficial effects of the utility model are: each Evaluation Platform in the visual assessment module in this utility model adopts the mode of simulation software playing pictures to replace the assessment mode of traditional papery picture, avoid error and careless mistake that anthropic factor causes, shorten the testing time, improve the reliability of test, alleviate the workload of busy voluntary labor service personnel, save a large amount of paper, for environmental protection cause makes tremendous contribution.In addition, data memory module have recorded old individual essential information, saves the data of a large amount of old sight assessment aspects, facilitates doctor's inquiry and provides reference data for diagnosis.Outut device facilitates tester and associated specialist print and check test result, and defines a large amount of old sight appreciation information data bases.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is theory diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of old sight evaluating system that this utility model provides, comprise software and hardware, software is based on Windows operating system, utilizes VC++ software development, hardware comprises main control system, the display device be connected with main control system, the input equipment be connected with main control system and outut device, main control system comprises visual assessment module, visual assessment module comprises central vision field Evaluation Platform, colour vision Evaluation Platform, identification capability Evaluation Platform in kind, described central vision field Evaluation Platform, colour vision Evaluation Platform, identification capability Evaluation Platform in kind is 3 PCs, central vision field Evaluation Platform comprises the Amsler grid table shown by display device, i.e. Amsler grid, colour vision Evaluation Platform comprises the pseudo-isochromatic diagram shown by display device, identification capability Evaluation Platform in kind comprises the pictorial diagram shown by display device, the corresponding Evaluation Platform in visual assessment module is entered by input equipment input command adapted thereto, and the assessment result of corresponding Evaluation Platform is exported by outut device.
In the present embodiment, preferred input equipment comprises keyboard and Mus mark; Outut device comprises printer.
As one preferred embodiment, main control system also comprises data memory module, and data memory module is connected with visual assessment module, for storing personal information and each assessment result of tester.
As one preferred embodiment, main control system also comprises data inquiry module, and data inquiry module is connected with data memory module, for reading the data in data memory module.
Degeneration of macula, preretinal membrane pathological changes and optic neuropathy and brain pathways for vision pathological changes can be detected by central vision field Evaluation Platform;
Utilize the operating procedure of this utility model detection tester vision specific as follows:
1, utilize the mouse in input equipment to open native system, by the individual essential information of input through keyboard tester, select the project of needs assessment, click and enter corresponding Evaluation Platform; Evaluation Platform comprises: central vision Evaluation Platform, colour vision Evaluation Platform and resolving ability Evaluation Platform in kind.
2, select central vision Evaluation Platform, display device demonstrates Amsler grid table; The display interface of this Evaluation Platform is provided with clear, fuzzyyer and very fuzzy three options, and tester selects according to oneself actual organoleptic conditions.The normal data of this Evaluation Platform association main control system setting, according to the selection that tester makes, provide central vision field normally, fuzzyyer and very fuzzy need do the assessment result of further inspection to ophthalmology.Particular exam step is as follows:
(1) the Amsler grid table of display is placed on eye-level display 30 centimeters; Require test room light nature.
(2) for ensureing that in tester's eye, uniform light is clear, can wearing spectacles in checking process.
