Glaucoma Diagnosis

Glaucoma is a disease where there is a raise in the intra-ocular pressure, optic disc changes and an associated visual field loss.

Intra - ocular pressure measurement
Applanation Tonometry
Non Contact Tonometry
Pascal DCT
Perkins tonometer
Reichert Ocular response analyzer
Rebound tonometer
Anterior segment Imaging ; Visante AS-OCT (Zeiss)
Optic nerve evaluation by
Digital Fundus photography (Zeiss)
GDx VCC nerve analyzer (Zeiss)
HD Optical Coherence Tomography (Zeiss)
Heidelberg retinal tomogram
Ultrasound Biomicroscopy
Swept source OCT
Visual field testing by
Humphrey Visual field analyzer
