Advantages:

To report the etiology, treatment and results of 8 patients with Valsalva retinopathy.

Methods:

Seven patients with sudden visual acuity loss due to Valsalva retinopathy were included in this study. Two patients underwent 20-G vitrectomy, 3 patients were treated with 23-G vitrectomy, in 2 patients no therapy deemed neccessary as the hemorrhage was small and resolved spontaneously after one month and 3 months, respectively; in another case we performed YAG-laser hyaloidotomy, and the hemorrhage disappeared within 2 months. Causes for the premacular hemorrhage were as following: vomiting in 3 cases, spontaneously in 2, weight lifting in 2, during pregnancy, after a general anesthesia for lipoma surgery, thoracoabdominal trauma, dance in one case each. Mean age of the 7 patients was 30 years. Two patients had been treated unsuccessfully with YAG-laser before surgery was performed. Complete clinical examination with best-corrected visual acuity (Snellen scale), intraocular pressure, fundus examination, fundus photography and optical coherence tomography was performed before treatment and during follow-up in all cases. Mean follow-up was 52.3 months (26-116 months).

Effectiveness/safety:

One week after surgery 4 out of 5 surgically treated patients had clear optic media, visual acuity has increased to 10/10 and remained stable during follow-up. One patients received laser treatment and SF6-gas tamponade because of an intraoperative retinal break. In 2 patients the hemorrhage did not involve the macula or was small and resolved without treatment. In another case the hemorrhage resolved after YAG-laser hyaloidotomy and the visual acuity improved to 10/10. In all patients that had surgery, the blood was located under internal limiting membrane.

In conclusion:

Valsalva retinopathy is a rare condition that may cause sudden visual acuity loss. Treatment options depend on the size and amout of hemorrhage and range from observation to laser hyloidotomy and vitrectomy.
