Silicone oil injection in conjunction with pars plana vitrectomy is associated with many post-operative complications in the eye. Emulsification of silicone oil may fill the space in the superior portion of the anterior chamber and manifest as an "inverted hypopyon" or "hyperoleon".
We report a case of a 27 year-old female with a history of retinal detachment in the right eye, which came to our Hospital referring intermitent right eye blurred vision. Slit lamp examination showed an inverted hypopyon in the upper portion of the anterior chamber, a finding consistent with the leakage of silicone oil from vitreous chamber to the anterior chamber.
