Valsalva retinopathy was firstly described in 1972 by Thomas Duane as a particular form of retinopathy characterized by preretinal bleeding secondary to a sudden increase in intrathoracic pressure (Duane 1972, 1973). Hemorrhage typically occurs in the macular region (Fig. 6.1) and may resolve spontaneously within a few days or take months for complete reabsorption (Gass 1987). It usually affects young adults causing unilateral low visual acuity sudden and painless. Cases of bilateral involvement have been described (Durukan et al. 2008). The prolonged period of contact between the blood and the retina may lead to complications with risk of persistence of impaired visual acuity (Nili AhmadAbadi et al. 2009).
