Overview

Students will expand their knowledge on first year topics from Cell Biology and Physiology to learn about basic eye pathology. Topics include types of microorganisms, transmission and control of infection, genetics and eye disease, introduction to epidemiology and how the body responds to injury and infection

Aims

 To outline the different types of microorganisms and pathogens that the eye is exposed to 
 
 To outline the main diseases that these microorganisms cause and that Optometrists will have to deal with in practice. 
 
 To describe basic eye pathology from a symptomatic viewpoint.
 

Learning outcomes

·         To be aware of the different types of micro-organisms, and those that are pathological

·         To understand how pathogens are transmitted and how infection is controlled

·         To learn about the types and uses of epidemiological studies and disease prevention

·         To learn some basic concepts relating to ocular disease

·         To learn about disease classification, cell injury, inflammation, wound healing, genetic disease, environmental disease

·         To learn about assessment of ocular disease and the signs, symptoms and differential diagnosis for a range of presenting ocular disease cases.

·         To learn about the most common systemic diseases with ocular consequences

 

Syllabus

Types of micro-organisms - beneficial and harmful

• Body defences

• Transmission and control of infection

• Introduction to epidemiology

• Genetics and eye disease

• Introduction to ocular disease

• How the body responds to injury and infection

• Presentation and diagnosis for: sudden loss of vision, gradual loss of vision, the red eye, watering/dry eyes, eyelid and     orbital swellings, eye trauma, systemic disease, squints, the child that does not see and eye emergencies.

Employability skills

Analytical skills
Students will be presented with a variety of evidence-based findings regarding pathogen transmission, spread control and diseases caused by these. Students will be also presented with a variety of systemic, and genetic diseases affecting the eye, their causes, signs and symptoms. Students will therefore develop the skills to analyse such scientific evidence.
Group/team working
Students will spend time with a small group preparing topics to present in front of the whole class. They will be encouraged to discuss their findings regarding different genetic diseases and their treatments (i.e. gene therapy).
Oral communication
Students will be presenting a range of topics in small groups in front of the rest of the class.
Problem solving
Students will need to extract information from a broad range of sources in order to put together a presentation and a discussion about a topic that will be assigned to them.
Research
Students will be encouraged to use a variety of resources: websites, journal papers and textbooks. Students will be encouraged to extract the relevant information from trusted sources.
