Removal of subfoveal perfluorocarbon droplet combined with internal limiting membrane peeling to flatten the macular

Dear Editor,I’m Dr.Dan Li from the Department of Suzhou Kowloon Hospital,Shanghai Jiao Tong University School of Medicine,Suzhou,Jiangsu Province,China.I’m writing to present an interesting case.It is well known that retained subretinal perfluorocarbon droplets are a possible surgical complication after intravitreal injection of perfluorocarbon liquid(PFCL).The retinal neuroepithelial layer and retinal pigment epithelial layer cannot be bonded where it located.The retina is in a state of detachment.When the patient is lying on the bed,due to the action of gravity,the subretinal PFCL will gradually shift to the posterior pole,especially the macular region.Subfoveal PFCL droplet may seriously affect the visual function.Clinicians are committed to finding a method of removing subfoveal PFCL with less damage.We recently encountered a case of this complication,reported here.
