Inducing a PVD

Usually it is easy to induce a posterior vitreous detachment, but some times the posterior hyaloid face can be very resistant to coming off...

Here is one such case, after trying all the usual manouvres which failed, I decided to 'stain' the vitreous with triamcinolone and then mechanically peel the posterior hyaloid face till I could develop the plane of separation. Once tha was achieved, engaging and pulling up the posterior hyaloid face with the ocutome was easy.
