Perforating ocular injuries due to exploding beverage bottles are well known. However, bottle caps alone may also induce severe ocular damage due to ocular contusions while opening carbon dioxide-containing beverage bottles. We studied this type of ocular contusion. ⋯ Bottle cap injuries are not as harmless as supposed. Bottle caps may induce severe ocular damage due to the high-impact energy.

To present epidemiological data on eyelid trauma which appear rarely in the literature. ⋯ In eyelid trauma, the lid margin is affected in 24% and the lacrimal drainage system in 16% of all injuries. Our data also showed a high association (44%) of eyelid injuries with trauma to the eyeball. This emphasises the necessity for eyelid injuries to be treated primarily by an ophthalmic surgeon, although difficult primary reconstruction and early complications in particular, are relatively rare.

[Ophthalmodynamometry. A reliable procedure for noninvasive determination of intracranial pressure].
Central vein pressure depends on intracranial pressure (ICP). Baurmann in 1925 therefore recommended measuring central vein pressure to determine ICP, but the accuracy of this method has not yet been verified. To test the method we measured venous outflow pressure (VOP) by noninvasive ophthalmodynamometry (ODM). ⋯ Measuring VOP by ODM seems to be a reliable method for noninvasive recording of ICP. It is a useful screening test in all cases of presumed ICP elevation.

Various methods have been used in the treatment of trichiasis: epilation, excision, cryosurgery, thermocaustic needle, and argon laser. None of these is satisfactory. Based on the principle of selective photothermolysis for destroying specifically the hair follicle, we used a diode laser and evaluated its efficacy. ⋯ The diode laser is a useful tool for the treatment of trichiasis. The laser parameters, however, should be ameliorated.

Comparative Study
[Preoperative infection prophylaxis with 1% polyvidon-iodine solution based on the example of conjunctival staphylococci].
Most germs causing postoperative endophthalmitis derive from the conjunctival bacterial normal flora. Postoperative endophthalmitis is often induced by staphylococcal germs. The application of polyvidone-iodine solution to the conjunctiva is one possibility to reduce potential endophthalmitis-causing bacteria. The aim of this study was to evaluate the effectiveness of 1% polyvidone-iodine solution concerning the reduction of colonization with staphylococci in the course of intraocular surgery. This is to evaluate the effectiveness of 1% polyvidone-iodine solution concerning coagulase-negative and positive staphylococci. ⋯ We concluded that a significant reduction of a staphylococcal colonization can be achieved by preoperative application of polyvidone-iodine (1%) (P < 0.001). Even at the end of surgery the effect of 1% polyvidone-iodine solution held.
