Purpose: To report a case of bilateral angle-closure associated with systemic hantavirus infection. Materials and methods: A 32-year-old Caucasian man was referred with blurred vision, fever, cough, dyspnea and thrombocytopenia. Ophthalmologic examination revealed myopic shift, elevated intraocular pressure (30 mmHg right eye and 24 mmHg left eye), corneal edema, iridocorneal angle closure and shallow anterior chamber. Ciliochoroidal effusion was detected on anterior segment optical coherence tomography and ultrasound biomicroscopy. Serologic test and polymerase chain reaction confirmed the diagnosis of hantavirus infection and the serotype Puumala. On the sixth day after he started topical anti-glaucoma and cycloplegic medications, the anterior chamber and iridocorneal angles were normalized with disappearance of ciliochoroidal effusion. Conclusion: Puumala hantavirus infection is an exceptional cause of acute bilateral angle-closure combined with ciliochoroidal effusion.

The introduction of anterior-segment optical-coherence tomography (AS-OCT) has led to improved assessments of the anatomy of the iridocorneal-angle and diagnoses of several mechanisms of angle closure which often result in raised intraocular pressure (IOP). Continuous advancements in AS-OCT technology and software, along with an extensive research in the field, have resulted in a wide range of possible parameters that may be used to diagnose and follow up on patients with this spectrum of diseases. However, the clinical relevance of such variables needs to be explored thoroughly. The aim of the present review is to summarize the current evidence supporting the use of AS-OCT for the diagnosis and follow-up of several iridocorneal-angle and anterior-chamber alterations, focusing on the advantages and downsides of this technology.
