Automated Diabetic Retinopathy Diagnosis for Improved Clinical Decision Support.

We report on the prediction performance of artificial intelligence components embedded into a telehealth platform underlying a newly established eye screening service connecting metropolitan-based ophthalmologists to patients in remote indigenous communities in Northern Territory and Queensland. Two AI-based components embedded into the telehealth platform were evaluated on retinal images collected from 328 unique patients: an image quality alert system and a diabetic retinopathy detection system. Compared to ophthalmologists, at an individual image level, the image quality detection algorithm was correct 72% of the time, and 85% accurate at a patient level. The retinopathy detection algorithm was correct 85% accurate at an individual image level, and 87% accurate at a patient level. This evaluation provides assurances for future service models using AI to complement and support decisions of eye health assessment teams.

The Molecular Epidemiology of Ocular Chlamydia trachomatis Infections in Western Australia: Implications for Trachoma Control

We studied the serovar distribution of Chlamydia trachomatis in patients with clinical eye disease in Western Australia. Most disease occurred in indigenous communities and was caused by trachoma serovars Ba and C. Serovar Ba was genetically homogeneous throughout Western Australia and identical to strains previously described in indigenous communities in Northern Territory. This finding probably results from movement of these populations, and suggests that a widely coordinated, rather than local or regional, approach is needed to control trachoma in mobile populations. Serovar C strains within Western Australia were homogeneous but distinct from those in Northern Territory, possibly because of inherent differences in transmissibility or differences in population movements among communities carrying the different serovars. Genital serovars were occasional causes of eye diseases in infants, adolescents, and adults in trachoma-endemic areas. These serovars should be considered in the differential diagnosis of acute follicular conjunctivitis in these groups.
