This article reports a case of bilateral corneal pellucid marginal degeneration. The right cornea had an acute hydrops. Both eyes underwent penetrating keratoplasty. A histopathological study of the corneal specimens was performed by light and electron microscopy. The histological changes observed on the right cornea showed breaks on Bowman's layer, edema and disorganization of the stromal collagen, and break of Descemet's membrane. The ultrastructural changes were similar to those observed in acute keratoconus, leading to the belief that these two corneal diseases are closely related.

[Pars plana phacoemulsification. Technics, indications and results].

Pars plana phacoemulsification allows cataract extraction through a 3 mm posterior sclerotomy. The indications of these technics are the combined cataract-vitrectomy, the cataracts on vitrectomised eyes and cataracts on eyes filled with silicone oil. The alteration of corneal endothelium is very reduced with the endocapsular pars plana phacoemulsification. After the emulsification, the capsular bag is extracted with a microforceps through the pars plana. It is also possible to save the anterior capsule to reduce corneal alteration during endocular surgery. We present the indications and the advantages of these technics.
