**4.3 Case 3**

An 81 year old man with a history of cataract extraction in both eyes, glaucoma and penetrating keratoplasty in right eye in 2000, was referred to the Department of Ophthalmology of San Matteo General Hospital with ocular pain and marked reduction of visual acuity. In spite of risks connected with his glaucomatous history, the patient opted for new surgical treatment and on October 2003 he underwent a new penetrating keratoplasty.

On the first post-operative control was referred Descemet's retention from removed graft. On September 2004 the graft appeared oedematous and with a lot of new vessels all around the limbus. Because of this on November 23, 2004 was performed a new penetrating keratoplasty in right eye. On the last control (September 2010) the patient's visual acuity in his right eye was limited to hand motions.
