The Ocuplot semi-automatic visual field screener--technical evaluation and clinical results

Area of Science:

• Ophthalmology
• Medical Device Technology

Background:

• The Ocuplot is a device for visual field testing.
• Previous versions of the Ocuplot have been available.
• The manufacturer claims improvements in newer Ocuplot models.

Purpose of the Study:

• To evaluate the perimetric concept and technical construction of the Ocuplot.
• To assess the efficiency and accuracy of the Ocuplot's test strategy.

Main Methods:

• Evaluation of the mechanical and electrical construction of the Ocuplot.
• Examination of 87 eyes from patients and normal subjects using the Ocuplot.
• Analysis of clinical results from patient examinations.

Main Results:

• The mechanical and electrical construction of the tested Ocuplot was found to be poor.
• The Ocuplot's test strategy is inefficient.
• A high proportion of false positive results were observed during testing.

Conclusions:

• The Ocuplot's current design and test strategy are suboptimal for clinical use.
• Further improvements are needed to enhance the Ocuplot's efficiency and reduce false positives.
