• Methodologies adopted
It is evident hitherto that depending on the type of expert system being developed, a single methodology is not sufficient for complete and successful development of the system. Therefore, in this study, a combination of methodologies were adopted. After evaluation of various research methodologies discussed above, the following methodologies were adopted for this study:
• Rule Based Expert System Methodology (RBESM)
• Object-Oriented Analysis and Design Methodology (OOADM)
3.2.2 Rule Based Expert System Methodology (RBESM)
A rule based expert system is a computer system which could do the work of human expert by relying on   sets of rules and facts supplied by the domain expert. It comprises Knowledge base (facts and rules), inference engine, interface and working memory.

Teleoptometry

The real time transmission of clinical and ocular information of a patient   from a remote site over a communication network, through interactive audiovisual media for the purpose of consulting and sometimes conducting clinical procedures or examinations is a possibility. Vision 2020 which targets to eliminate avoidable blindness by the year 2020 is facing multiple setbacks in some developing countries like Nigeria. These setbacks are more evident in the rural communities and include difficult terrain, lack of appropriate infrastructure, poor health care system, fragile communication system, epileptic or no power supply, low and anomalous distribution of eye doctors, etc.   A country such as India has specifically tackled such setbacks experienced in their health care system by taking advantage of modern digital networking   technology such as N-logue and   ATN. Today, the Indian citizenry has a success story to tell. With a simple webcam, laptop and headset, or ev...
