Corneal calcification after chemical eye burns caused by eye drops containing phosphate buffer.

Purpose: Chemical burns with calcium containing corrosives as well as irrigation with phosphate buffer solutions after eye burns bear the risk of corneal calcification. The aim of this study was to evaluate the correlation between the occurrence of corneal calcification after chemical injuries and the usage of phosphate buffer containing local therapeutics.

Methods: We reviewed the data of 179 patients who have been treated in the University Eye Clinic Aachen, Germany, between 1941 and 2000.

Relationship between foveal birefringence and visual acuity in neovascular age-related macular degeneration.

Purpose: To investigate the relationship between visual acuity and foveal birefringence in patients with neovascular age-related macular degeneration.

Methods: In total, 40 patients with choroidal neovascularization underwent macular imaging with scanning laser polarimetry. Bowtie patterns, typically seen in birefringence images of the macula, were evaluated and classified into three categories: (1) regular bowtie present; (2) bowtie present, but disrupted; and (3) no bowtie present.

Effect of different irrigating solutions on aqueous humour pH changes, intraocular pressure and histological findings after induced alkali burns.

Purpose: To evaluate the effects of hypo-osmolar tap water and isotonic saline solution on the intracameral pH, intraocular pressure and histological changes in alkali burned rabbit eyes.

Methods: Four groups of four rabbit corneas each were burned with 2 N sodium hydroxide, and then rinsed with 0.5 l or 1.

[HES 130 as a continuous supplement for organ culture of human corneas?].

Background: During organ culture, corneas swell and have to be de-swollen prior to transplantation using a medium. Both swelling and de-swelling lead to increased endothelial cell loss. Furthermore, dextran, the standard de-swelling substance, is toxic and deposited in the cornea.

Relationship of eye burns with calcifications of the cornea?

Introduction: The clinical pattern of corneal calcification has been considered to be a part of chronic eye diseases, such as uveitis, severe glaucoma, keratitis and eye burns. Since, in some cases of eye burns, we have found corneal calcifications to be related to the initial calciferous caustic agents and to the use of phosphate-buffer-containing fluids, we have reviewed our files of clinical eye burns for the incidence and appearance of corneal calcification.

Methods: A total of 176 burnt eyes of 98 patients suffering from severe eye burns were retrospectively reviewed.
