Posterior vitreous detachment and work efficiency: a case study.
The paper analyses a case report of a female worker whose job required prolonged near visual effort and who suffered from multiple ophthalmological disorders. The specific case of interaction between the visual apparatus of the operator and the tasks performed is discussed, with particular reference to the unstable compensation that different pathological disorders, when summed together, can produce, thus allowing to subjects to lead a normal working and social life for long periods of time without any limitations and without any significant asthenopic symptoms. Because this compensation is unstable, it can unexpectedly be impaired due to the onset of diseases not involving the visual apparatus. The scientific literature was analysed in order to assess, at least approximately, the prevalence of clinical/functional situations identical or similar to the case described.
