EVALUATION OF THE SENSITIVITY OF LARGE-ANGLE RETINOGRAPHY IN COMPARISON WITH RETINA MAPPING ASSOCIATED WITH ESCLERAL INDENTATION

Introdução / Purpose

Optomap is a device capable of recording retinal images in high resolution.
The new generation, Optomap 200DTx, displays 96º, 101º, 76º and 102º in superior, nasal, inferior and temporal region, respectively.
Today, the gold standard examination for evaluation of the peripheral retina is the mapping of retina with scleral indentation.
We will evaluate the sensitivity in the location of lesions predisposing to retinal detachment.

Material e Método / Methods

Retrospective, randomized and double-blind study. A random sample of 211 patients from the retina department of Centro Brasileiro da Visão who had a diagnosis of peripheral degeneration predisposing to retinal detachment. Each patient underwent a wide-angle retinal examination, Panoramic Ophthalmoscope P-200DTx Optos®.
We compared the number of peripheral lesions verified in the mapping with those found in the retinal image obtained. Both procedures were performed by different ophthalmologists, retina specialist.
Patients with diagnosis of peripheral lesion and with a wide angle image previously performed in the 4 quadrants were included. Patients with ocular anatomical alterations were excluded; aphakic; previous history of retinal detachment; retinal surgery.

Resultados / Results

We analyzed 211 medical records, excluding 111. We obtained 125 eyes from 85 patients who fit the criteria of inclusion and exclusion. The sites with the highest incidence of lesions were at 12h (17.1%) and at 6h (22.91%).
The optomap had a sensitivity of 78.4% and the regions with the highest loss index were 12h (5.6%) and 6h (6.4%), but the nasal and temporal regions had a 100% recovery.

Discussão e Conclusões / Conclusion

The field of view of Optomap has some limitations, such as eyelids and eyelashes. This may justify the difficulty in the location of the upper (12h) and lower (6h) lesions.
The low sensitivity, 78.4%, does not give us the confidence to perform this examination as a form of screening or as an alternative to retinal mapping.
