Purpose: To report a patient who simultaneously developed bilateral increased intraocular pressure and unilateral non-arteritic anterior ischemic optic neuropathy (NAION) after Sildenafil citrate (Viagra®) use.
Case summary: 60-year-old male was referred from other hospital by decreased vision of his left eye. 2 month ago, he visited other hospital’s ophthalmologic department by pain and sudden decrease of vision in left eye and. He had taken Sildenafil citrate 50 mg one day before, and symptom was first recognized after wake up in the morning. At that hospital, intraocular pressure (IOP) was 48 mm Hg and 50 mm Hg in his right and left eye. IOP was controlled by topical IOP-lowering agent. However, visual field constriction was not improved after treatment, the patient was referred to our ophthalmologic clinic. IOP was normal at the first visit, but diffuse constriction of visual field and pale optic disk was observed in his left eye. With the impression of NAION, regular outpatient follow up was done. During 3 months follow up period, IOP was stable but visual field was not improved.
Conclusions: There are several reports about increased intraocular pressure or development of NAION after Sildenafil use. To our best knowledge, this is the first case of developed increased intraocular pressure and unilateral NAION after Sildenafil use in Korea. Those who predisposed towards these diseases, special concern should be taken in using Sildenafil citrate.
