Abstract: Long durations of high blood sugar levels can cause fluid to build up in the focusing lens inside the eye in diabetics. This alters the lens's curvature, which affects how you see. However, the lens normally returns to its former shape and eyesight improves once blood sugar levels are under control. Diabetes patients with improved blood sugar management skills will delay the start and progression of diabetic retinopathy. AOA's 2018 American Eye-Q Survey found that nearly half of Americans were unaware of the existence of diabetic eye illnesses' visual signs (often which the early stages of diabetic retinopathy does not). The American Optometric Association (AOA) advises that everyone with diabetes have a comprehensive dilated eye examination at least once a year because a similar survey revealed that more than one-third of Americans were unaware that the only way to determine whether a person's diabetes will cause blindness is through a comprehensive eye exam. The risk of diabetic retinopathy causing major vision loss can be reduced with early detection and treatment. [1-3] Depending on the severity of the condition, there are many treatments for diabetic retinopathy. In order to stop blood vessels from leaking or to stop other blood vessels from leaking, people with diabetic retinopathy may require laser surgery. To reduce inflammation or inhibit the growth of new blood vessels, your Optometrist may need to inject drugs into your eye. [4-5] In this paper we will deal with image pre-processing and matrix handling. The second problem statement as mentioned in our previous introductory paper is technically dealt with in this paper.
