The microbiome and ophthalmic disease.

IMPACT STATEMENT: This review describes a growing body of research on relationships between the microbiome and eye disease. Several groups have investigated the microbiota of the ocular surface; dysregulation of this delicate ecosystem has been associated with a variety of pro-inflammatory states. Other research has explored the effects of the gastrointestinal microbiota on ophthalmic diseases. Characterizing the ways these microbiotas influence ophthalmic homeostasis and pathogenesis may lead to research on new techniques for managing ophthalmic disease.

Getting the picture: visual interpretation in ophthalmology residency training.

OBJECTIVES: Visual interpretation is essential in many fields of health care. Although diagnostic competency can be measured as an educational outcome, few accounts have addressed tacit aspects of visual interpretation in clinical training; these include the disciplining of the trainee's attentions and the trainee's acculturation into expected styles of communicating visual interpretations to others. This paper describes values and dispositions that are taught to ophthalmology trainees as they learn to reason through visual information, and explores how these qualities are evaluated during residency training. METHODS: The project was based on 6 months of ethnographic participant observation and interviews in an ophthalmology residency programme. Observational notes and interview transcripts pertaining to visual interpretation were isolated for qualitative analysis in the tradition of sociocultural anthropology, guided by literature on communication in medical education and the socialisation of health professionals. RESULTS: Residents and faculty members identified visual interpretation as one of the most challenging skills expected of ophthalmology trainees. They expressed a belief that 'systematic' approaches, where visual information is parsed in a stepwise fashion, reduce the chance of trainees overlooking or misinterpreting key diagnostic features. This sensory discipline was represented in narrative form when faculty members asked residents to interpret images aloud, as residents were expected to follow prescribed sequences for describing the content of images before commenting on possible diagnoses. CONCLUSIONS: Sensory processing is ordinarily opaque to outside observers, but the ritual of describing images in highly regimented narratives allows residents to demonstrate how they gather and reason through visual information. The form of these narratives reflects values that residents are expected to embody during their training, such as being thorough and methodical; it may also serve a pedagogical function by entrenching those values. Further research is needed to characterise how the performance of speech genres shapes the interpretive skills of medical trainees.
