UNVEILING THE POTENTIAL OF BLUE CHANNEL MONOCHROMATIC IMAGING IN RETINAL TEAR IDENTIFICATION

Introdução / Purpose

To explore the potential of blue channel enhancement in optical imaging for detecting peripheral retinal tears in patients with lower retinal pigment epithelium (RPE) pigmentation.

Material e Método / Methods

A retrospective, cross-sectional image analysis using a convenience sample. Retinal images of eight patients with retinal tears were divided into two groups: tears easily identifiable and delineated in color images, and tears considered challenging to visualize and delineate in color images (difficulty attributed to low RPE pigmentation). Color and monochromatic images were captured using the Clarus 700 retinal camera. RGB color and monochromatic images were qualitatively evaluated to determine the optimal modality for identifying and delineating retinal tears.

Resultados / Results

The blue channel image allowed for a better visualization of the lesions compared to the red-channel, green-channel and color fundus images in the lower RPE pigmentation group. It was useful in identifying the real extent of the peripheral retinal tear in patients of both groups.

Discussão e Conclusões / Conclusion

This method is cost-effective and non-invasive, which eliminates the need for more invasive procedures. The benefits of this approach are significant, as it offers a promising method for earlier detection and treatment of peripheral retinal tears. Identifying peripheral retinal tears in individuals with diminished retinal pigment epithelium (RPE) pigmentation presents a significant clinical challenge. The use of the blue channel in digital retinal imaging provides a cost-effective and non-invasive method for the identification of peripheral retinal tears in these patients and has the potential to be a valuable tool for early detection and treatment of such conditions. However, further investigations are warranted to ascertain the sensitivity and specificity of this method in detecting retinal lesions accurately.
