[Therapy of advanced amoeba keratitis with keratoplasty à chaud and adjuvant cryotherapy].

Background: Since the mid-1980s acanthamoeba keratitis has been diagnosed with increasing frequency, especially in contact lens wearers. The assignment to specialized centers is often delayed many months and there is hardly any chance of controlling the disease by conservative treatment alone. In these cases, penetrating keratoplasty offers the only chance for rehabilitation.

Atheromatous and atheroma-like lesions of the central retinal artery: histopathological correlations.

Arteriosclerosis is very rare in the distal central retinal artery (CRA) of aged eyes devoid of significant ocular pathology. Nevertheless, atheromatous and atheroma-like lesions are occasionally observed in routine ophthalmic pathology. We investigated the histopathologic correlations of the eyes and vessels involved.

Tophus-like, conglomerated, crystalline calcification of the sclera.

The clinical history and the pathohistological findings of a peculiar form of multifocal scleral calcification in 3 globes of 2 patients are described. It consisted of globular drusen of rod-like crystals, fusing into large, tophus-like conglomerates. The crystals consisted of monoclinic and triclinic calcium pyrophosphate.

Dystrophic calcification of an implanted hydroxyethylmethacrylate intraocular lens.

Hydroxyethylmethacrylate is a biomaterial still under clinical trial for use in foldable intraocular lenses. We observed a patient in whom a geographic opacification developed within an implanted hydroxyethylmethacrylate lens, together with granular deposits on the posterior lens capsule and in the scar of a paracentesis. The intraocular lens and posterior lens capsule were removed because of impaired visual acuity.

[Granuloma annulare of the eyelid].

Background: Granuloma annulare is a chronic inflammatory disease of connective tissue, manifested clinically by small, firm nodules. It is observed only rarely around the eyes.

Patients And Methods: We present four patients aged 33 to 66 years with papulomatous lesions of the eyelids.
