To report a case of secondary pulmonary arterial hypertension (PAH) and the relationship of intraocular pressure (IOP) change with right ventricular diameter (RVD) and brain natriuretic peptide (BNP).
Case report.
A 22-year-old woman with dilated and congested conjunctival and episcleral veins was diagnosed with high IOP. She was previously diagnosed with Sjögren syndrome and suffered from secondary PAH.
The RVD and BNP level improved and the IOP decreased with routine treatment for PAH. During self-cessation of treatment for PAH, the RVD, BNP level, and IOP deteriorated. However, they improved after treatment was reinitiated.
There was a synchronizing change in the parameters representing high pulmonary arterial pressure and IOP during treatment of PAH.
