Automated Retinopathy of Prematurity Case Detection with Convolutional Neural Networks
Retinopathy of Prematurity (ROP) is an ocular disease observed in premature babies, considered one of the largest preventable causes of childhood blindness. Problematically, the visual indicators of ROP are not well understood and neonatal fundus images are usually of poor quality and resolution. We investigate two ways to aid clinicians in ROP detection using convolutional neural networks (CNN): (1) We fine-tune a pretrained GoogLeNet as a ROP detector and with small modifications also return an approximate Bayesian posterior over disease presence. To the best of our knowledge, this is the first completely automated ROP detection system. (2) To further aid grading, we train a second CNN to return novel feature map visualizations of pathologies, learned directly from the data. These feature maps highlight discriminative information, which we believe may be used by clinicians with our classifier to aid in screening
Combined Hamartoma of the Retina and Rpe - An Unusual Cause of the Dragged Disk Appearance
Combined hamartoma of the retina and retinal pigment epithelium (RPE) is a rare, benign, congenital fundal lesion which contains a mixture of glial tissue, blood vessels and pigment epithelium. Such turnours are variably pigmented and may be wrongly diagnosed as malignant melanoma or retinoblastoma. We report two cases which were located in the periphery of the fundus and which produced a dragged disc appearance. Copyrigh
Results of anterior transposition of the inferior oblique
Purpose: We present the results of anterior transposition of the inferior oblique in a series of patients with inferior oblique overaction and dissociated vertical deviation (DVD). Patients and methods: We performed a retrospective study of 37 procedures on 21 patients who had unilateral or bilateral inferior oblique anterior transpositions. Before surgery, patients had +1 to +3 inferior oblique overaction and +1
