Ultra-wide field retinal imaging: A wider clinical perspective

Area of Science:

• Ophthalmology
• Medical Imaging

Background:

• Peripheral retinal involvement is common in many eye diseases.
• Traditional fundus cameras have limitations in visualizing the entire retina.
• Ultra-wide field imaging offers a comprehensive view of the retinal periphery.

Purpose of the Study:

• To review the utility of ultra-wide field imaging in assessing various retinal disorders.
• To highlight new observations made possible by ultra-wide field imaging.
• To describe the application of ultra-wide field imaging in clinical practice.

Main Methods:

• Literature search using keywords: "ultra-widefield imaging", "widefield imaging", "peripheral retinal imaging".
• Inclusion of relevant articles in English and non-English languages.
• Review of studies detailing imaging modalities like color, fluorescein angiography, indocyanine green angiography, and autofluorescence.

Main Results:

• Ultra-wide field imaging reveals peripheral retinal details in normal eyes and various pathologies.
• New observations have been made in vascular, degenerative, inflammatory, and hereditary retinal diseases.
• The technique facilitates detailed assessment of conditions like age-related macular degeneration, uveitis, and tumors.

Conclusions:

• Ultra-wide field imaging is a valuable tool for examining the peripheral retina.
• It enhances the diagnosis and understanding of a wide spectrum of retinal disorders.
• This imaging modality expands diagnostic capabilities beyond traditional methods.
