Preoperative B-scan ultrasonography of the vitreoretinal interface in phakic patients undergoing rhegmatogenous retinal detachment repair and its prognostic significance.
To perform ultrasonographic evaluation of the preoperative status of the posterior vitreoretinal interface in phakic patients undergoing surgery for retinal detachment (RD) with flap tear(s) and to investigate its relationship with postoperative anatomic and visual acuity outcomes. ⋯ In phakic patients with retinal detachment and flap tear(s), a higher primary anatomic success rate may be associated with the presence of a complete PVD compared to a partial PVD. Subgroup analysis suggests that the presence of partial PVD at baseline might influence negatively the primary anatomic success rate, particularly for eyes undergoing pneumatic retinopexy.

High-density silicone oil (Densiron) as a primary intraocular tamponade: 12-month follow up.
The high-density silicone oil (Densiron 68), a mixture of F6H8 with silicone oil, seems to be a therapeutic option, at least in selected patients with complex inferior retinal re-detachment, where standard procedures have already failed. In an interventional case series we used Densiron as a primary endotamponade. ⋯ Primary anatomical success rate of 33.3% was less encouraging than as expected. Especially, re-detachments within the posterior staphyloma in highly myopic patients were common during Densiron endotamponade. However, the surgical success increased to 75% after reintervention, even without the use of an additional encircling band. The observed adverse effects and the functional outcomes do not contraindicate the use of Densiron as an internal tamponade for a period of 3 months.

Impact of new lamellar techniques of keratoplasty on eye bank activity.
Deep anterior lamellar keratoplasty (DALK) has become an increasingly popular alternative to penetrating keratoplasty in patients with stromal corneal pathologies. The main advantages of DALK are: prevention of long-term endothelial loss, elimination of allograft reaction and short topical steroid treatment with lower risks of glaucoma, cataract and infection. Because this technique enables surgeons to use corneal grafts with low endothelial density, the aim of this paper was to determine whether this type of innovation has had a significant impact on eye bank activity. ⋯ Deep anterior lamellar keratoplasty development and close collaboration between eye banks and surgeons can induce a significant increase in corneal grafting. This could be a partial solution in countries confronted with corneal graft shortages.

In vivo confocal microscopy of pigmented conjunctival tumors.
To analyze the appearance of conjunctival pigmented tumors as seen by in vivo confocal microscopy. ⋯ High correlations were found between in vivo confocal microscopy using near-infrared laser light and histology in the diagnosis of pigmented conjunctival lesions. In vivo confocal microscopy seems to be a valuable new tool in the differential diagnosis and follow-up of pigmented conjunctival tumors. It does not replace histology, but may assist in performing guided biopsy in tumors suspected clinically and/or with in vivo microscopy. In addition, in vivo confocal microscopy may support the clinical diagnosis of extrascleral involvement in uveal melanoma.
