Optic Disc and Optic Cup Segmentation for Glaucoma Detection
Glaucoma is an eye disease that leads to vision loss. The symptoms of the glaucoma occurs when disease is quite advance. Glaucoma is called ‘silent thief of sight’ so, that early detection of glaucoma is very essential. In existing approach three methods are used to detect glaucoma namely Assessment of raised intraocular pressure (IOP).Assessment of abnormal visual field. Assessment of damaged ...
متن کاملClustering Based Optic Disc and Optic Cup Segmentation for Glaucoma Detection
Glaucoma is a chronic eye disease that leads to vision loss. As it cannot be cured, detecting the disease in time is important. Current tests using Intra Ocular Pressure (IOP) are not sensitive enough for population based glaucoma screening. Optic nerve head assessment in retinal fundus images is both more promising and superior. The method to segment optic disc and optic cup using Simple Linea...
متن کاملOptic Disc and Optic Cup Segmentation Methodologies for Glaucoma Image Detection: A Survey
Glaucoma is the second leading cause of loss of vision in the world. Examining the head of optic nerve (cup-to-disc ratio) is very important for diagnosing glaucoma and for patient monitoring after diagnosis. Images of optic disc and optic cup are acquired by fundus camera as well as Optical Coherence Tomography. The optic disc and optic cup segmentation techniques are used to isolate the relev...
متن کاملOptic Disc and Cup Segmentation for glaucoma Screening based on Superpixel classification
Glaucoma is a chronic eye disease that leads to blindness. This disease cannot be cured but we can detect the disease in time. Current tests using intraocular pressure (IOP) measurement are not sensitive enough for population based glaucoma screening. Optic nerve head assessment in retinal fundus images is more promising and superior than current methods. This paper proposes segmentation of opt...
متن کاملPhotogrammetric Measurement of the Optic Disc Cup in Glaucoma
Cupping of the optic disc associated with the atrophy of the optic nerve is one of the earliest recognizable signs of glaucoma . Measurements of the optic cup changes would provide objective evaluation in early diagnosis and therapy of glaucomatous eyes, by following the course of the patient in relation to the loss of visual field and medical or surgical control . A semi-analytical photogramme...
