Dear Editor,

Cyanopsia is a term for seeing things tinted with blue. There are few case reports of cyanopsia developing after cataract surgery [1, 2] and ingestion of phosphodiesterase inhibitors such as sildenafil and vardenafil [3, 4]. Here, we report a patient who complained of cyanopsia as an early symptom of compressive optic neuropathy.

Case report

A 63-year-old man noticed cyanopsia OD 1 month ago. Cyanopsia lasted for a few days and then he experienced a sense of generalized dimness in the right eye compared to that in the left eye. Since then, he also noticed progressive exophthalmos and intermittent retrobulbar pain deep in the right eye unrelated to eye movement.

On examination, his best-corrected visual acuities were 20/200 OD and 20/25 OS by Snellen visual acuity test. Intraocular pressures were 17 mmHg OU. Slit lamp examination showed a mild cataract of nuclear sclerosis grade 2 OU. Pupillary light reflex revealed a relative afferent pupillary defect OD. Ocular deviation...
