The symptoms can start slowly leading to vision loss one may not notice them. Treatment at an early stage can prevent the further vision loss. A thorough dilated eye exam is the only approach to detect glaucoma. In this paper an eight-layer based Convolutional Neural Network architecture is proposed for the detection of glaucoma. For image distinction, CNN provides a hierarchical structure of the pictures. With a total of eight layers the proposed work can be evaluated. The image is preprocessed using techniques like resizing, gray scaling, CLAHE. Further segmentation is done using canny edge detection. Using CNN the system classifies the images as normal eye or glaucoma eye based on the features extracted during training. The proposed methodology manages to obtain high classification accuracy thus demonstrating the system's dependability and promise.
which is font and nearer to the lens of the eye. Therefore, for light to reach and activate the rods and cones, it must first pass through the retina and activate the rods and cones, it must first pass through the retina's thickness.

1.1 Retinal diseases
Following that, the photons that are absorbed by the visual pigment of the photoreceptors are transformed into an electrical message that can subsequently activate all of the retina's succeeding neurons. The retinal communication regarding the photic input and some preliminary structuring of the visual image into various sorts of emotion is transmitted to the brain via the ganglion cells' spiking discharge pattern.
Our eyes send our brain one-fifth of the information it receives. Many both common and uncommon eye disorders can impair eyesight. For eyesight to be clear, the retina must be healthy. Due to the fact that they can affect any area of the retina, retinal disorders are common. The following are possible diseases.
1. INTRODUCTION The rear of the eye's interior is lined with a thin layer of tissue called the retina. It is located near to the optic nerve. The retina's job is to collect the light that the lens has focused, transform it into neural signals, and convey those signals to the brain for visual identification.
Diabetic Retinopathy
There is a layer of photoreceptor cells in the retina that process light. In essence, these are light-sensitive cells that can recognize characteristics like color and light intensity. After the photoreceptor cells collect the information, it is analyzed by the retina and transmitted to the brain through optic nerve. In general, the concentrated light creates an image for the retina to analyze, and the brain is then left to determine what the visual is.
Diabetes has a side effect called diabetic retinopathy, which can damage the retina and lead to blindness. The eye's essential sustaining blood vessels deteriorate, deviate, and multiply inexplicably. The most popular form of treatment today for preventing blood vessel growth and fluid leaking into the retina is laser therapy.
The retina is nearly 0.5mm thick that extends down the rear side of the eye. The optic nerve also has incoming blood arteries that flow into the retina in addition to the ganglion cell axons that proceeds to the brain. It vascularize the retinal layers and neurons. The photosensors, or rods and cones, are situated next to the pigment epithelium and choroid, while the ganglion cells, which are the retina's
Cataracts are the term for the blinding of the eye's lens. Normally, this region is unobstructed. Light rays are prevented from going through the lens and focusing on the retina when this clouding takes place. A tissue lining that is sensitive to light is the retina. It is situated behind the eye. When a portion of the protein that makes up the eye's lens
