Intravitreal Injection of Triamcinolone Acetonide (TA) for the Treatment of Retinal and Choroidal Detachment Caused by Idiopathic Orbital Inflammation

Background: Idiopathic orbital inflammation (IOI) is a benign, space - occupying orbital lesion with no identifiable local or systemic cause that affects the orbit. The inflammation associated with IOI can induce choroidal edema and subretinal fluid accumulation, which in turn contribute to retinal and choroidal detachments. This report details a case of recurrent IOI complicated by cataract, presenting as a shallow anterior chamber accompanied by retinal and choroidal detachment. After cataract surgery and intravitreal injection of triamcinolone acetonide (TA), favorable therapeutic outcomes were obtained. Case presentation: The authors highlight the treatment of recurrent IOI complicated with cataracts, shallow anterior chamber, choroidal detachment, and retinal detachment. Initially, a 10 - day course of steroid therapy was administered, which included oral intake, topical steroid eye drops, and parabulbar dexamethasone injections. However, the response to this treatment was insufficient. Consequently, cataract phacoemulsification and intravitreal injection of triamcinolone acetonide (TA) were carried out. Post - treatment, during the follow - up period, the patient's visual acuity improved, and the choroid and retina reattached. Conclusions : For patients with retinal and choroidal detachment induced by IOI and concomitant cataract, cataract surgery in combination with intravitreal injection of TA is capable of effectively controlling inflammation, enhancing visual acuity, and facilitating the reattachment of the choroid and retina.
