Corneal bee sting-induced endothelial changes.

PURPOSE: To report the acute management and clinical findings of a case of corneal bee sting and to report the outcome of corneal endothelial cell analysis 1 year after trauma. METHODS: Clinical findings, anterior segment photographs, corneal endothelial images, and medical treatment of a case of right corneal bee sting are presented. Right and left central corneal endothelial cell analysis was performed by noncontact specular microscopy. RESULTS: The stinger was removed from the cornea. Systemic, subconjunctival, and topical steroids and systemic and topical antibiotics were given. One year later, a corneal scar and anterior capsular opacity of the lens in the right eye were shown by slit-lamp examination. Endothelial cell analysis determined that the endothelial cell density of the right eye was substantially decreased compared with the left eye. CONCLUSION: Corneal infiltration gradually decreased, presumably because of the systemic, topical, and subconjunctival steroids. Late complications observed in this case included a substantial decrease in cornea endothelial cell density, a corneal scar, and anterior capsular opacity.

Corneal endothelial polymegethism and pleomorphism induced by daily-wear rigid gas-permeable contact lenses.

PURPOSE: To determine if there are any corneal endothelial cell size and shape changes (and the time course of these changes) in subjects wearing rigid high gas-permeable (RGP) contact lenses for daily wear. METHODS: Ninety-seven eyes of 57 new wearers were fitted with a fluoroperm contact lens material (Persecon92E, oxygen transmissibility (Dk)= 92 x 10(-11)). Prior to lens wear and after 1 week, 1 month, 3 months, 6 months, and 1 year, noncontact endothelial photographs were taken. Maximum cell size/Minimum cell size (Max/Min) was measured as an index of polymegethism and the relative frequency of 5-, 6-, and 7-sided cells was evaluated. RESULTS: An increase in the ratio of Max/Min was present 1 week after lens fitting and increased further over the subsequent year. This study showed significant increase in endothelial polymegethism and in the relative frequency of 7-sided cells, but a significant decrease in the relative frequency of 6-sided cells. CONCLUSIONS: Daily-wear high Dk gas-permeable contact lenses can cause endothelial polymegethism and pleomorphism similar to those caused by soft and hard contact lenses.

Two cases of Stenotrophomonas maltophilia endophthalmitis.

Two cases of Stenotrophomonas maltophilia endophthalmitis, a rare cause of postoperative endophthalmitis, are reported in this study. Both of the patients underwent vitreus tap and intravitreal antibiotic injection. The therapy was augmented with systemic and subconjunctival injections. The response to this therapy protocol was excellent and the final visual acuity in both of the patients was 10/10. The results are discussed and the literature, which consists of only 8 reported cases of Stenotrophomonas maltophilia endophthalmitis, is reviewed. Although endophthalmitis caused by this pathogen is a rare but important cataract surgery complication, with appropriate therapy, this clinical presentation can be cured without risk of reoccurrence.
