Bee stings of the cornea are rarely reported but can potentially cause serious ophthalmologic injuries. Locally, damage occurs through toxic and immunologic reactions and from the stinger retained in the cornea. ⋯ Removal of a retained bee stinger remains controversial. We present a case of corneal bee sting with retained stinger apparatus and associated anterior uveitis and discuss the pathologic mechanisms of injury and evaluation of these uncommon presentations.

Orbital organic foreign bodies are rare and can present different clinical features. The objective of this report is to show the danger of this type of foreign body, present the imaging data, and suggest a diagnostic approach and therapeutic management. We describe three cases of orbital organic foreign bodies with three different clinical presentations. ⋯ Detecting an orbital organic foreign body is sometimes difficult, especially when the clinical history is unclear, the ophthalmologic exam reveals no abnormalities, or if the patient is referred to the hospital several months after the traumatic event. Orbital organic foreign bodies can lead to potentially serious orbital or intracranial complications. Computed tomography and orbital ultrasound sometimes do not yield an evocative pattern: for instance, in computed tomography, the low density of wood can be misdiagnosed as air. On the other hand, these foreign bodies can persist in the orbit after several surgical explorations because they can easily break or migrate. Magnetic resonance imaging is useful when an orbital organic foreign body is suspected, but the analysis is easier when clinical data are suggestive.

The use of anti-VEGF by intravitreal injection is being generalized, and the indications are multiplying. Ocular hypertension after injection can be a classic complication. ⋯ Elevation of intraocular pressure is frequent a short time after an intravitreal injection. However, this complication is more often moderate and transient, and does not usually require an adapted treatment. The physiopathology remains unclear. To our knowledge the occurrence of acute angle-closure glaucoma following an intravitreal injection is exceptional.

To assess the patient characteristics, risk factors, and outcomes of penetrating keratoplasty wound dehiscence. ⋯ Patients with corneal transplants have a life-long risk for wound traumatic dehiscence. This complication may be reduced by the regular use of eye protection by all corneal transplantation patients.

[Peribulbar anesthesia: efficacy of a single injection with a limited local anesthetic volume].
Cataract surgery can be performed with peribulbar anesthesia. The classical technique consists of two injections of local anesthetics. The purpose of our study was to assess peribulbar anesthesia with a single injection and a limited volume of local anesthetics. ⋯ Peribulbar anesthesia performed with a single injection and a limited volume of local anesthetics allows cataract surgery in good conditions for the surgeon with very good analgesia for the patient.
