Official title
Comparison of Topical Hydrocortisone Versus Dexamethasone Treatment for Inflammatory Secretions of the Conjonctiva in Patients With Ocular Prostheses
Overview
We propose to evaluate the efficacy of treatment with Hydrocortisone and Dexamethasone (in a cross-over design) in patients with ocular prostheses and significant functional discomfort.
Detailed description
There are more than 100,000 eye prosthesis wearers in France. Half of these patients are bothered by secretions or sandy sensations, or even chronic pain. Various anti-inflammatory treatments are proposed without scientific basis.
A pilot study on a limited number of patients conducted in 2017 at the University Hospital of Rennes and published in 2019 showed the interest of Dexamethasone eye drops in these patients. However, this study was retrospective and not controlled.
We therefore wish to propose a prospective, placebo-controlled, single-blind clinical study to define the value of anti-inflammatory treatment in patients with ocular prostheses.
We propose to evaluate the efficacy of treatment with Hydrocortisone and Dexamethasone (in a cross-over design) in patients with ocular prostheses and significant functional discomfort.
