A comparison of four projection perimeters. Instrument specifications

Area of Science:

• Ophthalmology
• Medical Device Technology

Background:

• The Goldmann projection perimeter has been a standard in visual field testing.
• Advancements in technology have led to the development of alternative projection perimeters.

Purpose of the Study:

• To compare the features of the original Goldmann perimeter with three other available projection perimeters.
• To provide an overview of the Goldmann, Topcon, Marco, and Rodenstock machines.

Main Methods:

• A comparative analysis of the design and features of four projection perimeters.
• Examination of the Goldmann, Topcon, Marco, and Rodenstock machines.

Main Results:

• Detailed examination of the features of each of the four projection perimeters.
• Identification of similarities and differences between the Goldmann, Topcon, Marco, and Rodenstock models.

Conclusions:

• The availability of multiple projection perimeters offers clinicians a range of options for visual field testing.
• Understanding the specific features of each machine is crucial for selecting the appropriate device for patient needs.
