Abstract
Introduction. Valsalva retinopathy is an uncommon disorder that usually presents with acute onset of unilateral, or less frequently, bilateral visual impairment varying from subtle scotoma to total vision loss. It occurs as a result of Valsalva’s maneuver. In the vast majority of cases, hemorrhage is preretinal although subretinal, intraretinal and vitreous hemorrhage can be found. Valsalva retinopathy often develops due to numerous triggering activities such as vomiting, coughing, heavy weight lifting, intense aerobic exercise, labor and general anesthesia. Management options are either clinical observation or invasive techniques. We report a case of premacular hemorrhage due to Valsalva retinopathy induced by gym training. Case Outline. A 34 year-old woman was referred to the Eye Clinic, University Clinical Center of Serbia, complaining of sudden and painless unilateral decrease in vision occurred during intense physical activity. Best corrected visual acuity was measured as counting fingers at five meters distance. Dilated fundoscopy demonstrated a large, well demarcated premacular subhyaloid hemorrhage with visible rupture of the retinal vein branch. The patient was treated conservatively. Three months after the onset of symptoms, hemorrhage absorbed and best corrected visual acuity was 20/20. Conclusion. Valsalva retinopathy, although a rare condition, should not be omitted as a differential diagnosis of retinal and vitreous hemorrhages. Standard, observational treatment is generally sufficient for complete recovery of vision, however literature suggests that an individualized approach to each patient is required.
