RESUMO
RESUMO

Objetivo:

comparar a acurácia do diagnóstico de tumor palpebral por avaliação de fotos obtidas por câmera convencional versus câmera acoplada em smartphone.

Métodos:

trinta e seis pacientes foram submetidos a exame externo e exame biomicroscópico para estabelecimento de diagnóstico clínico. As lesões foram fotografadas com câmera convencional Canon SX530 HS, digital de 16,8 megapixels e com câmera do smartphone modelo GALAXY S4. Todas as lesões foram ressecadas e submetidas a exame anatomopatológico. As imagens pré-operatórias foram analisadas à distância por dois especialistas em doenças palpebrais. Os dados dos diagnósticos presencial e dos teleavaliadores foram confrontados com o padrão ouro do diagnóstico histológico.

Resultados:

as lesões mais frequentes foram constituídas por carcinoma basocelular (33,3%), queratose actínica (19,4%) e nevo (13,9%). O coeficiente de Kappa para diagnóstico de lesão maligna mostrou concordância entre os teleavaliadores nas imagens por câmera (0,68) e com smartphone (0,78). A acurácia do examinador presencial foi de 94,4%, a dos teleavaliadores nas imagens por câmera foi de 83,3% e as do smartphone variou entre 80,6% e 86,1%. Não houve diferença nos índices de acerto por uso de câmera ou smartphone quando comparado com o exame presencial.

Conclusão:

imagens obtidas por smartphone foram equiparáveis em relação à câmera convencional para uso em telemedicina para diagnóstico de lesão maligna palpebral.
ABSTRACT
ABSTRACT

Objective:

to compare the accuracy of eyelid tumor diagnosis obtained by evaluating conventional camera images with the ones obtained by evaluating smartphone images.

Methods:

from January 2016 to July 2017, 36 patients underwent face-to-face external assessments and biomicroscopic examinations to establish clinical diagnoses. The lesions were photographed using Canon PowerShot SX530 HS Digital Camera (16.8 Megapixels) and Samsung GALAXY S4 smartphone camera. All lesions were resected and submitted to anatomopathological examinations. Preoperative images were sent to two specialists in eyelid diseases and then remotely analyzed. Data from in-person diagnoses and telediagnoses were compared with the gold standard of histological diagnosis.

Results:

the most frequent lesions were basal cell carcinoma (33.3%), actinic keratosis (19.4%), and nevus (13.9%). Kappa coefficient for the diagnosis of malignant lesion showed agreement between the two tele-evaluators in the conventional digital camera images (0.68) and in the smartphone images (0.78). The face-to-face examiner's accuracy was of 94.4%; the tele-evaluators' accuracy in the conventional digital camera images was of 83.3% and in the smartphone images varied from 80.6% to 86.1%. Comparing the in-person diagnoses with the telediagnoses (obtained by evaluating conventional digital camera images or smartphone images), there was no significant difference in the hit rates.

Conclusion:

for eyelid tumor telediagnosis, images obtained using smartphone camera were equivalent to those obtained using conventional digital camera.
