Diagnostic tools for early glaucoma detection: A review
Dr. P Pundareekaksha Rao
Glaucoma is a chronic neurodegenerative disease characterized by death or loss of retinal ganglion cells and their axons. The loss of retinal ganglion cells results in typical structural changes in the Optic Nerve Head and the Retinal Nerve Fibre Layer. It develops silently without any warning signs. Early detection of glaucoma with different modalities is very important because many peoples who have the glaucoma do not know they have it. The main goal of treatment is to either stop or slow disease progression; it is possible with early assessment. Glaucoma, Most clinicians diagnosed with corresponding structural and functional changes. The essential elements of evolution include: Tonometry, Gonioscopy, Perimetry etc. Additional testing i.e. Imaging Technologies is necessary to asses glaucoma in early stages to prevent further development. This review article provides brief description about new advances in different aspects of glaucoma diagnosis.
