Case Reports[Traumatic wound dehiscence and corneal rupture 3 1/2 years after radial keratotomy].
Severe complications such as a traumatic wound dehiscence have been described very rarely after radial keratotomy. The following case demonstrates for the first time that wound healing is not completed even 31/2 years postoperatively and that therefore an ocular blunt trauma may still cause a dehiscence of the radial incisions. ⋯ Even several years after surgery, blunt traumas represent a definite risk for eyes undergoing radial keratotomy.

[Postoperative leakage of silicone oil into the anterior chamber].
One reason for complications after silicone oil application is the postoperative entrance of silicone oil into the anterior chamber. In a retrospective study, we tried to define risk factors for oil entrance into the anterior chamber. ⋯ It seems that in the early postoperative period the frequency of oil entrance into the anterior chamber can only be lowered by a subtotal oil filling in aphakic eyes with accompanying encircling procedures. It remains open if radical amputation of the vitreous base can avoid peripheral reproliferations.

Review Comparative Study[Peribulbar anesthesia versus retrobulbar anesthesia with facial nerve block. Techniques, local anesthetics and additives, akinesia and sensory block, complications].
Retrobulbar anesthesia (RETRO), combined with a facial block, is the most frequently employed method of anesthesia in cataract surgery. There is, however, an increasing tendency to use peribulbar anesthesia (PERI), which is claimed to provide the same degree of anesthesia and akinesia as RETRO while reducing many of the complications. ⋯ In randomized order, 160 cataract patients received PERI (technique with 2 injections) with 6, 8 or 10 ml of a bupivacaine-lidocaine-hyaluronidase mixture (without facial block) or RETRO (Unsöld technique) with 5 ml of the above mixture, combined with a Nadbath/Rehman facial nerve block (5 ml etidocaine-lidocaine mixture). Measured 20 min after injection (intervening period of oculopression), the smallest ocular motility (Kestenbaum limbus test) was left after RETRO. After administration of PERI - even with a volume of 10 ml - the range of residual ocular motility was always higher, i.e., there was a less reliable globe akinesia than after RETRO. The lid closure force (Straub technique) averaged zero after all methods of anesthesia; however, the smallest spread (highest reliability) was observed after PERI. Complete corneal anesthesia (Draeger esthesiometer) was found in nearly all cases, i.e., RETRO and PERI are comparably effective concerning sensory blockade...

Case Reports[Self-inflicted injuries of the eye: differential diagnosis of self-inflicted lacerating corneal injury].
Recognising self-inflicted injuries is the prerequisite to initiate specific, psychiatric, therapy of the often underlying psychiatric disorders. The differential diagnosis of Oedipism, self-inflicted ocular injury, includes Munchausen's-syndrome, neuroses and schizophrenic psychoses. ⋯ In patients with unexplained ocular disease self-inflicted ocular injury needs to be taken into consideration as the treatment of such patients requires close cooperation of Ophthalmologists and Psychiatrists.

[Chemical and thermal eye burns in the residential area of RWTH Aachen. Analysis of accidents in 1 year using a new automated documentation of findings].
Until now there were no statistical data on the incidence and the prevalence of eye burns. Therefore we studied all patients coming to our hospital from the area of Aachen with eye burns during the time from September 1990 until August 1991. ⋯ By means of a one-year statistic we found that over 60% of all eye burns were industrial accidents, 28 in machine factories and 20% in service industries. 37% houseworks accidents are very difficult to prevent because of a deficit of safety rules.
