The Equator-Plus camera provides a wide 148-degree fundus view, significantly larger than conventional cameras. This advanced imaging technique successfully captured detailed retinal images in 87% of clinical tests without complications.

Area of Science:

Ophthalmology
Medical Imaging
Optics

Background:

Conventional fundus cameras offer a limited field of view.
Diagnosing extensive fundus pathologies can be challenging with standard imaging equipment.

Purpose of the Study:

To evaluate the clinical utility of the Equator-Plus camera for wide-field fundus photography.
To assess the image quality and diagnostic capabilities of the Equator-Plus system.

Main Methods:

The Equator-Plus camera, featuring a 148-degree field of view achieved via a specialized contact lens, was clinically tested.
Over 700 eyes were photographed more than 800 times.

Main Results:

The Equator-Plus camera captured images with a field of view three to four times larger than conventional cameras.

Lesions as small as one-eighth of a disk diameter were resolvable.

Good quality images were obtained in 87% of clinical tests.

The technique effectively visualized protruding tumors, choroidal/retinal detachment, and extensive choroidal/fundus disease.

Conclusions:

The Equator-Plus camera is a valuable tool for wide-field fundus imaging.
It offers improved visualization of retinal and choroidal pathologies.
The camera demonstrated a high success rate and no observed complications during clinical use.
