Humphrey Matrix Visual Field Instrument

  • The Humphrey Matrix comes equipped with software for comprehensive threshold exams and charting change over time. It is clinically validated by numerous studies.

Optomap MachineOptomap

The optomap ultra-wide digital retinal imaging system captures more than 80% of your retina in one panoramic image. Traditional methods typically reveal only 10-15% of your retina at one time. The unique optomap ultra-wide view enhances your eye doctor’s ability to detect even the earliest sign of disease that appears on your retina. Seeing most of the retina at once allows more time for your eye doctor to review your images and educate you about your eye health.

  • Age-related macular degeneration (AMD) and diabetic retinopathy are two of the most common causes of blindness.
  • The digital camera that Dr. Cleveland uses captures images that can be viewed immediately, making procedures more efficient. Because the images are digital, they can be used with many different applications.
  • This powerful digital camera technology enables refined images of the retina to assist Dr. Cleveland in detecting and monitoring diabetes, glaucoma, and other serious conditions.
