Intravitreal dexamethasone implant — a new treatment for idiopathic posterior scleritis: A case report

摘要

BACKGROUND Posterior scleritis is one of the most easily missed and misdiagnosed diseases in ophthalmology.In this case we treated a patient with intravitreal dexamethasone implant that has not been extensively studied before.CASE SUMMARY A 40-year-old female patient who had anxiety,palpitation,and insomnia presented with eye pain and decreased vision in the left eye.An eye examination indicated that her visual acuity(VA)was 40/100.Her left eye presented conjunctival edema,mild exophthalmos,clear cornea,KP(-),and clear aqueous humor.In the fundus,there was a cinerous retinal protuberance.Ultrasonography showed“T-sign”and no systemic association was detected in laboratory examination.One month after injection of dexamethasone implant,the patient exhibited VA of 20/20,fundus serous retinal detachment disappeared,and intraocular pressure of both eyes was at the normal level.CONCLUSION Intravitreal injection of dexamethasone implant may be a safe and effective treatment for patients with idiopathic posterior scleritis.
