Case Reports[The surprising finding and removal of a large plastic foreign body through the corneal wound from the vitreous cavity with good outcome].
Presented is a patient whose history showed that during a hammer-blow on a piece of iron something had flown into his left eye. Clinical investigation revealed a 9-mm long, horizontal, paracentrally located, penetrating corneal wound. Temporally in the same region the iris was torn in its entire width. The lens appeared opaque and seemed to be cut in two parts. Radiological investigation revealed no foreign body. ⋯ Operative treatment of patients with a penetrating eye injury is always demanding and difficult and requires a lot of experience. Particularly in apparently hopeless cases, an optimum primary care is of greatest importance.

[Topical anesthesia as routine procedure in cataract surgery -- evaluation of pain and complications in 1010 cases].
The number of cataract surgeries using topical anesthesia has increased continuously in the United States in the last years. Over 60 % of all cataract surgeons accept this form of anesthesia as first choice in cataract surgery. Surgeons in German-speaking countries still prefer injection anesthesia. Patient pain and complications during cataract surgery under topical anesthesia were recorded in 1010 cases to find out if topical anesthesia will become established as a routine procedure in Germany. ⋯ Topical anesthesia using tetracaine drops with adjunctive intracameral injection of non-preserved lidocaine 1 % is a safe and efficient form of anesthesia in phacoemulsification and is well tolerated by patients. According to the patients' positive assessment and the low rate of complications, drop anesthesia is well suited for clinical routine.

Comparative Study Clinical Trial Controlled Clinical Trial[Impact of prostaglandin-F(2alpha)-analogues and carbonic anhydrase inhibitors on central corneal thickness -- a cross-sectional study on 403 eyes].
Histological changes of, in particular, collagen and extracellular matrix after administration of topical prostaglandin F(2alpha)(PGF (2alpha)) analogues have been reported. In view of this observation, we investigated the influence of PGF(2alpha) analogues on the central corneal thickness. ⋯ The present findings suggest that the topical application of prostaglandin F(2alpha) analogues onto the cornea reduces the central corneal thickness significantly. These changes might be attributed to effects of PGF(2alpha) analogues on the extracellular matrix of the corneal stroma via upregulation of matrix metalloproteinases. In clinical practice, corneal thinning under local PGF (2)(alpha) analogue treatment could result in underestimation of intraocular pressure levels as measured by applanation tonometry.

Comparative Study[Cataract surgery under topical anesthesia with oral anticoagulants].
Approximately 14 % of cataract surgery patients receive blood-thinning agents. In a prospective study, the influence of oral anticoagulants on intraoperative and postoperative hemorrhages in patients undergoing cataract surgery in topical anesthesia was investigated. ⋯ Cataract surgery in topical anesthesia under oral anticoagulation did not increase the risk of sight-threatening hemorrhages. The continuation of oral anticoagulation seems particularly indicated for ambulatory cataract surgery.

Multicenter Study Clinical Trial[Epidemiology of open globe eye injuries: analysis of 1026 cases in 18 years].
Ocular trauma has significant impact on the patient's future quality of life. Progress in the treatment of ocular trauma may ameliorate the outcome, but preventive measures are more effective. However, prevention of ocular trauma can only be effective when the current epidemiology of ocular trauma is known. Therefore, we have now collected data on ocular trauma over nearly 20 years. This paper provides an overview on the development of open globe injuries in the past 20 years. ⋯ There is a relative constant incidence of 3.0 open globe injuries per 100,000 population. The circumstances of the injuries underwent major changes within the period of these observations.
