ABSTRACT
The diabetic retinopathy is defining as a types of disease from which it can infected to
retina of eyes. In this disease, blood vessels get swells, blood leakage occur and some other sighs
occur. There are various other symptoms occur from this disease such as blurred vision, loss of
vision and dark vision. As there are various complication occur with this problem as improper
development of blood vessels occur in this. Under this report, the impact of diabetic retinopathy
is covered as it has various impact on health condition of a human. The obesity, kidney problems
and other occurs at starting stage of occurrence of this disease. There are various factors which
helps in occurrence of disease in eye of human. The untreated of this disease can also cause
various problem in eyes as person can become fully blind. There are some cause which
contribute in occurrence of this disease such as presence high level of blood glucose in human
body. It also includes the presence of other previous eyes cataracts which enhance eyes
contraction and makes the person blind and blurred. There are various ways from which diabetic
retinopathy can be treated.
BACKGROUND
The clinical research proposal is necessary to conduct as it provides relevant information
about any study. As the more relevant studies are published which help in assisting researcher in
identifying cause of it. This is necessary to be undertake by researcher from which they can
influence their information properly. The most appropriate studies are mainly published on a
specific subject. That help in assisting researcher in their subject. With this the researcher can
analyse appropriate information about any topic. This also help in deliver services according to
relevant information. As the evidence based practices is an appropriate manner of providing
services to people.
INTRODUCTION
The diabetic retinopathy is a common type of disease that occur due to changes in blood
vessels (Portney, 2020). This is occurring in retina of eye which is present in back of eye that
help in changing light into images. In this condition, swelling of blood vessels, leakage of blood

and other symptoms occur (Pencina, 2016). If this disease left undiagnosed then it can damage
retina. It generally occurs in diabetic patients who has type 2 diabetes1.
The impact of diabetic retinopathy on health of patient within 6 months.
According to the views of Fenwick (2020), the various impact of diabetic retinopathy
occurs on health of patient. The new blood vessels in eyes are does not grow properly(Irwin,
2019). It also includes flow of bleeding which impacted on retina which cause casual loss of
irreversible vision (Taylor, 2017). The hypertension, obesity and kidney problems are some
other conditions which impacted on health patient along with eye problem (Fenwick, 2020). If
this disease left untreated then it can cause permanent loss of vision which is refer to as Macular
Oedema2.
The 5 causes and factors contributing to the occurrence of diabetic retinopathy
According to the views of Lima (2020), there are some causes which contribute in
occurrence of diabetic retinopathy (Fain, 2017). The cause of behind this disease occur such as
glaucoma, macular degeneration, refractive error, cataracts and level of high blood glucose
which enhance loss of vision and blindness3. These all causes deterioration of retina with
different conditions that result in blurred vision of eye (Patten, 2016). The factors are depending
on manner of cause and process of diabetic retinopathy (Ambe, 2016). The factors which
contribute in occurrence of this disease are such as duration of disease, age, hyperglycaemia,
inflammation and genetic factors4.

The 2 effective ways of diagnosing and treating diabetic retinopathy
According to the views of Lee (2020), the diagnoses of diabetic retinopathy can be
occurring by examining through doctors (Mauro, 2017). This can be developing by two ways
methods which are pupil dilation and fluorescein angiogram (Boxberg, 2017). The treatment is
based on type of diabetic retinopathy disease that are present in body (Khalilzadeh, 2017). It
includes Anti-VEGF injection therapy and scatter laser surgery5.

METHODS
The quantitative research is used to collecting information by investigating from service
users by using method of sampling. The researcher collect data by conducting questionnaire and
surveys. It is used to identify issues with help of numerical data that can turned into statistics.
This is an emphasised by use of communication with population that includes questions which
state about behaviour and perception of people. With this research, the data can be collected by
using graphs in a rank order. The data are collected from interviews, clinical trials and close
questions. The qualitative method is used to identify data with the help of observation in order to
get non numerical information. It includes symbols, definitions and description of any thing. It
involves documents, questionnaires, interviews that help in gathering information. In this
proposal, quantitative method is used for research along with primary and secondary sources to
collect data and information.
Resources
The resources are referring to origin of collecting information from which the research
has been conducted. There are two types of resources which are described below.
Primary sources: - the information is collected from interviews, observation, surveys
and questionnaire, etc. the data can be collected from first handed by researcher to conduct any

inquiry. This can be conduct on a special time period in which they collect data about any
information. It represents original thinking of respondents6.
Secondary sources: - in this research, data is collected from another person analysis. The
secondary resources can be collected through journals, books and other ways that are already
conducted. It describes the identification, analyse and evaluation of primary resources. This can
be occurring through verbally or non-verbally by written or non-written methods7.
Sampling
The sampling refers to procedure of examining data in which it planned. It includes
amount of sample that are taken to analyse from bigger population of service providers. This
depends on type of analyse that are used for identifying larger population. It includes random
sampling method.
Random sampling: - It is the manner of sample which is collected for observation. In
this technique each sample is chosen as equal probability. This technique is occurring from
unbiased cooperation with respondents. In this members are selected randomly and it helps in
making general for large member of population. The sample size is used in this is for 40
respondents8.
Ethical and legal considerations
The Ethical principles is one of the most important part of research. It is necessary to be
conduct at time of research as it assist in maintaining dignity of respondents appropriately. The
respondents should not be accessible to any injury in a every aspects. It is important to hold
respect of respondents. The confidentiality of principles is occurring in central system of medical
in which personal health of patients are maintain including their private information. This cannot
be disclosed without their permission. The legal principles are also necessary to consider as it

helps in describing laws which are for respondents. So that they dos not receive harm from any
researcher.
Time course
Gantt chart: this is a graph representation which stated or show interrelation between all
activities. It assists in facilitate various information that are linked with task which are necessary
to be completed in time. The project manager can be providing outline of activities that are
performing. This help in completion of activities or project on time as the task can be occur
properly.

DATA PROCESSING AND ANALYSIS
The data analysis can be used to identify data from various sources and information.
From different sources, it has been gathered and reviewed which help in analysing data with sort
of findings. In this, R programming is used for analysis of data. This programme is mainly used
to analyse data and statistics from appropriate source. With help of this, data is effectively
gathered and secured in a confidentially place which does not disclose to anyone.
