To report a case of punctate inner choroidopathy (PIC) which was effective in intravitreal dexamethasone implantation.
A 23-year-old woman presented with decreased vision in her right eye for 1 week. She had mumps twice a week ago, and there were no other underlying diseases. On ophthalmic examination, the refractive error was -8.00 diopters in the right eye and -8.50 diopters in the left eye. The best corrected visual acuity (BCVA) was 0.7 in the right eye and 0.9 in the left eye. On slit lamp examination, there was no inflammation in the anterior chamber and vitreous body. There were multiple yellowish white spots on macular area. Multiple retinal pigment epithelial detachments and outer retinal disruptions were observed on optical coherence tomography (OCT). More extensive multiple hypofluorescent lesions than fluorescent angiography (FAG) were observed in late phase on indocyanine green angiography (ICGA).
Therefore, we diagnosed as punctate inner choroidopathy (PIC) and used oral steroids. At 1 month of treatment, the BCVA and fundus findings were improved, but steroids were tapered due to side effects. At 2 months of treatment, the the BCVA and fundus findings were worsen and side effects were persist. After 4 months of treatment, oral steroids were discontinued and intravitreal dexamethasone implant (Ozurdex®; Allergan, Irvine, CA, USA) was injected. At 2 months after injection, the BCVA was 0.9 and inactive lesions with scar were observed on fundus examination.
We report a case of punctate inner choroidopathy (PIC) in which oral steroid use was limited, but improved on intravitreal dexamethasone implant injection.
