Functional status in glaucoma is best evaluated with perimetry; Visual acuity is insufficient, since it usually remains normal until very late in the process of glaucomatous disease.

Here, you will learn about Standard Automated Perimetry (SAP) and its relationship to glaucoma. First, you will learn why perimetry is necessary in the management of glaucoma. Next, you’ll go through some basic concepts of perimetry. After that, you’ll learn how to select a test, including non-standard perimetric tests, and the importance of constancy of tests for follow-up. Then, you’ll learn about the glaucomatous visual field. In particular, how to interpret the visual field and how to analyse events and trends.

Gonioscopy is an important diagnostic test in ophthalmology to correctly diagnose and properly treat each individual patient.In this module, you will learn about the principles of Gonioscopy, its importance, the type of lenses and classification systems.

Intraocular pressure (IOP) is the pressure of the fluid inside the eye.

Here, you will learn about Intraocular Pressure (IOP) and its relationship to glaucoma.

First, you can go through the basics of IOP. Then, you will find different Tonometers with brief descriptions. Next, there are some statistics of normal and abnormal IOP. Finally, you will read about fluctuation and variations of IOP and their clinical significance.

Examining the ONH is a key skill of ophthalmologists, optometrists and other eye care professionals.

Glaucoma prevalence studies have identified that up to half of all glaucoma patients are not aware that they have this disease. Furthermore a significant proportion of these ‘missed’ patients have seen an eye care professional previously. Why is the diagnosis of glaucoma missed? Here you will learn about the Optic Nerve Head clinical examination. This may produce the only information to alert the clinician about a sight threatening diagnosis.
