The combined A- and B-scan echography reliably separates intraocular melanoma from other intraocular lesion. This is showed by the analysis of 79 cases with clinically certain or possible melanoma during the last three years. In all 33 enucleated eyes the histology proved the echographic diagnosis of melanoma to be correct.

Ulzerierende herpetische Keratitis

Ophthalmologica (1984)

A. Lücke E. Landolt R. Witmer

Between 1971 and 1982 33 corneae were excised for therapeutic keratoplasty because of ulcerative herpetic keratitis. The histologic findings and the clinical course enabled distinction of a nonreactive form with a rather good prognosis for keratoplasty (62% clear grafts) and an inflammatory form with bad prognosis (20% clear grafts) because of many herpetic recurrences. Perforating keratoplasty and first interventions in particular did better than lamellar keratoplasty or retransplantation. Existence of preoperative corneal vascularization compromised the prognosis of the graft. Preoperative perforation of the ulcer occurred rather often in nonvascularized corneae without compromising the prognosis of the graft.

Three patients presented an unilateral whitish cloudiness of the corneal epithelium which reduced the vision considerably. In two cases, radiotherapy was carried out previously (because of pterygium and because of teleangiectasia of the conjunctiva). In the eye of one patient, a superficial corneal lesion developed during general anesthesia. The corneal epithelium was scraped off in all cases, but the opacities reappeared. Histologically, the epithelium showed dyskeratosis with signs of malignancy. --7 illustrations (3 sketches of the corneas, 4 histological photographs).
