To evaluate the French waiting list and the indications of registered patients, to compare the rates of registration, graft, and procurement between French regions. ⋯ Ophthalmologists will be able to register their patients directly on the waiting list, which will improve data quality for transplantation notification. Regional policies should be developed to decrease the inequalities of graft shortages between regions.

Randomized Controlled Trial Comparative Study Clinical Trial
[Peribulbar anesthesia: comparing 1% ropivacaine and a mixture of 0.5% bupivacaine--2% lidocaine].
To compare the efficacy of 1% ropivacaine with a mixture of 0.5% bupivacaine and 2% lidocaine in peribulbar anesthesia for elective cataract surgery. ⋯ No difference between the groups was noted during the study regarding not only onset time, but also the duration of anesthesia and perioperative analgesia. A greater incidence of pain on injection was significantly reported in group 2 (p<0.001). Patients in group 1 had less need for top-up injection and showed better ocular akinesia (p<0.01).

Orbital emphysema is a common complication of orbital wall fractures (50% of blow-out fractures). It is generally a benign and self-limited condition. However, it may compromise retinal and optic nerve vascularization and therefore requires rapid management. ⋯ The development of orbital emphysema after an orbital fracture is a consequence of a forceful expiratory effort raising intranasal pressure. It must be drained, as described, in cases of vascular compression.

Case Reports
[Air bags and eye injuries: chemical burns and major traumatic ocular lesions--a case study].
The authors report a case of bilateral eye lesions with extended visual sequelae after the inflation of a driver's airbag during a head-on collision. The superficial facial lesions were accompanied by bilateral eye lesions, reaching both the anterior and posterior segments. Bilateral periorbital palpebral hematomas; voluminous bipalpebral edema combined with severe -conjunctival edema, corneal erosions, and edema; bilateral hyphema; pupillary changes with multiple iris sphincter breaks and weak pupillary light reflex only on the right eye; retrocession of the iridocorneal angle; and on fundus examination both retinas had posterior and peripheral hemorrhages and Berlin retinal edema. ⋯ The American studies distinguish three factors affecting the seriousness of these airbag accidents: (a) wearing glasses, (b) position and size of the driver, and (c) inflation force of the airbag. Wearing a seatbelt is mandatory to minimize the violence of the oculofacial impact. After facial trauma from an airbag, an ophthalmological examination is necessary to assess of the chemical burns of the tissues exposed to the alkaline powder and possible major ocular lesions.

To report the results of limbal transplantation in patients with severe ocular burns and limbal stem cell deficiency. ⋯ Limbal transplantation is a useful surgical technique in patients with severe ocular burns. However, results remain insufficient and new techniques such as limbal stem cell culture and transplantation are needed to improve the visual prognosis of these patients.
