BMJ Case Reports authors have described how a patient’s vision deteriorated six hours after an uncomplicated labour.
The 25-year-old patient was referred to the ophthalmology department where clinicians determined that her vision was limited to counting fingers close to her face in both eyes.
A fundus examination revealed bilateral vitreous haemorrhage with subhyaloid haemorrhage in the right eye.
The patient was diagnosed with valsalva retinopathy. A pars plana vitrectomy was performed in the left eye and in the right eye three months later.
At a follow-up visit, the patient’s Snellen visual acuity was 20/40 in the left eye and 20/50 in the right eye.
The authors explain that valsalva retinopathy can occur soon after a forceful exhalation with closed glottis due to a sudden increase in intrathoracic and intra-abdominal pressure.
The condition has been linked to a variety of activities including constipation, pregnancy, sneezing, weightlifting and sex.
