![]() ![]() On the other hand, the prospects for a degrowth paradigm shift remain bleak: unlike political projects that became hegemonic in the past, degrowth has neither support from a comprehensive coalition of social forces nor any consent to its agenda among the broader population. What would it take for a degrowth paradigm shift to take place? Drawing on contemporary critical political economy scholarship, this article identifies four prerequisites for socio-economic paradigm shifts: deep crisis, an alternative political project, a comprehensive coalition of social forces. The Prerequisites for a Degrowth Paradigm Shift The selected topics illustrate the principles of these paradigm shifts and should serve as a guide to further research and development. This overview of paradigm shifts in ophthalmology suggests that the future will see significant improvements in ophthalmic diagnostics. Oxygen metabolism and circulatory physiology are measurable indices of ocular health that can detect variations of physiology and early disease. Non-invasive nanotechnologies can assess molecular changes in the lens, vitreous, and macula that predate visible pathology. Advances in our understanding of the genetic basis of eye diseases will enable better characterization of ocular health and disease. Distortions can be quantified and the psychophysical basis of vision can be better evaluated than in the past by designing tests that assess particular macular cell function(s). Vision can be evaluated beyond visual acuity by measuring contrast sensitivity, color vision, and macular function, as these provide better insights into the impact of aging and disease. Non-invasive nanotechnologies will enable a paradigm shift from disease detection on a cellular level to a sub-cellular molecular level. The definition of disease will incorporate genotype into what has historically been a phenotype-centric discipline. It is our impression that future evaluation of vision will go beyond visual acuity to assess ocular health in terms of psychophysical function. Specific topics have been selected to illustrate the principles of important paradigm shifts that will influence the future of ophthalmic diagnostics. This is not a review nor meant to be comprehensive. Practical methods to define genotypes will be increasingly important and non-invasive nanotechnologies are needed to detect molecular changes that predate histopathology. ![]() Sebag, J Sadun, Alfredo A Pierce, Eric Aįuture advances in ophthalmology will see a paradigm shift in diagnostics from a focus on dysfunction and disease to better measures of psychophysical function and health.
