Background/objectives: Late presentation of congenital cataract in the developing world has led to poor outcomes such that cataract is the leading cause of childhood blindness. Our hypothesis was that, sensitivity of red-reflex testing is greater than sensitivity of torchlight examination. We aimed to compare sensitivity of new red reflex screening tools and assess the feasibility of Arclight red reflex screening in the community.
Subject/methods: We compared the diagnostic accuracy of four different screening tools for cataract and retinoblastoma performed by ophthalmic nurses, using a clinic based enriched sample of 41 positives and 60 negatives. We then conducted a separate feasibility study, training non-specialist community nurses. Following the training, community nurses examined 2827 children <5 years with Arclight who were attending their clinics for growth monitoring and immunisation.
Findings: Diagnostic accuracy study: estimated sensitivities were 97.6% for Catcam, 92.7% for Arclight, 90.2% for PEEK retina and 7.3% for torchlight. Estimated specificities were above 90% for Catcam, Arclight and torchlight and 87% for PEEK retina. Feasibility study: twenty-four out of 2728 children screened failed community screening, seven were true positive (six cataract, one retinoblastoma). Prevalence of bilateral cataract was 1.5/1000 (95% CI: 0.40-3.75 per 1000).
Conclusions: Arclight and CatCam have higher sensitivity than torchlight, are easy to learn and use by primary health care nurses. Red reflex testing should be recommended in the WHO guidelines instead of torchlight examination to help early detection of potential blinding causes including congenital cataract and retinoblastoma.

To evaluate the two-year fundus examination outcomes of term infants undergoing eye screening. Retrospective review of our data of term infants at a tertiary care center (Ankara Bilkent City Hospital) from October 2021 to October 2023. All screened infants underwent red reflex test and dilated posterior segment examination.

The pupillary direct and consensual reflex is an important non-invasive quick assessment of the neurological state of the eye. Currently, there is no cheap and affordable recording tool for screening and documentation of a relative afferent pupillary defect. We describe how to construct a frugal, do-it-yourself handheld scotopic binocular pupillometer device called Pupilmate.

Hearing and vision disorders in newborns are a serious social and public health problem. To improve the effectiveness and efficiency of screening protocols, it is necessary to use standardized procedures and ensure their implementation at a national level. This is the first set of Italian national practice recommendations for professionals involved in the diagnosis, treatment, and management of hearing and eye screening that will guide the development of multidisciplinary services and public health policies to prevent and/or treat hearing and vision impairment in newborns.

Purpose: Double-tract reconstruction (DTR) is one of the major procedures following proximal gastrectomy (PG) with anti-reflex function for the esophagus. Although many studies demonstrated the feasibility of laparoscopic DTR, there is a lack of research on robotic DTR. We aimed to assess the safety and feasibility of robotic DTR following PG.

Rather than looking at which instruments to put in the traditional physician's black bag, the changing face of medicine suggests that some virtual assets assume prime importance. With a solid background of core knowledge and skills acquired through medical school but continuously developed and updated, several habitual attitudes are advocated-each aiming to address a different facet of concerns in today's time-constrained, often impersonal, fast-changing, information-overloaded, and highly technological practice. They include humility, curiosity, "red flag" identification, and reflexive database consultation-each with myriad, diverse advantages.
