Purpose: To report two cases of idiopathic intraocular cilia presenting as sectoral scleritis with progressive intraocular inflammation.Methods: Both patients were treated with intravitreal antibiotics and underwent pars plana vitrectomy where the cilia were removed and identified on histopathology.Results: One patient developed a retinal detachment while being treated for presumed endophthalmitis. The intraocular cilium was discovered during pars plana vitrectomy. In the second case, the cilium was detected on dilated fundus exam and was believed to be the cause of the patient's scleritis and vitritis. Therapeutic vitrectomy was performed. In both cases, the cilia were positively identified on histopathology.Conclusion: Idiopathic intraocular penetration of cilia should be considered in the differential diagnosis of sectoral scleritis with progressive intraocular inflammation.
