The activity of Cu,Zn superoxide dismutase in the fluid obtained from eye lens capsules after cataract surgery was investigated in samples obtained from patients with senile cataract and with senile cataract combined with diabetes mellitus. Two parameters were measured and compared:the frequency of occurrence of detected superoxide dismutase activity and the relative activity of the enzyme in samples derived from senile cataract patients versus those from the patiens affected additionally by diabetes mellitus. It was confirmed that the decrease of superoxide dismutase activity during cataract was additionally promoted by diabetes mellitus.

We present the case report of the first identification of Acanthamoeba as a causative agent of keratitis in the Slovak Republic. For the first time, Acanthamoeba sp. Group III was isolated from a 53-year-old patient with keratitis, which was manifested after an injury of the right eye. A delayed visit to a physician as well as a late diagnosis of the illness led to the advanced stage of eye disease. As the treatment with itraconazol and cornea transplantation showed no result, enucleation of the eye was decided. Acanthamoeba ludgunensis was also the causative agent of keratitis in a 39-year-old patient wearing contact lenses. His complaints occurred a month after bathing in a thermal swimming pool. The symptoms presented in the left eye were those of herpetic keratitis, and led to a cloudy cornea with circular infliltrate and poor vision. A prompt clinical and laboratory diagnosis, along with treatment with propamidine-isetionate resulted in a significant improvement of the eye condition. Contact lenses were probably related to another case of Acanthamoeba keratitis. The patient, a 15-year-old girl, kept wearing contact lenses during bathing in various swimming pools and in the sea; her contact lenses were also regularly washed under tap water. Due to the fact that cysts of Acanthamoeba sp. group II were found in the contact lens solution, this is presumed to be the source of the eye infection.

Cathepsin A activity assayed with N-Cbz-Phe-Ala, N-Cbz-Glu-Tyr and N-Cbz- -Glu-Phe as substrates, was measured in fresh corneas, lenses, aqueous humor, vitreous humor and choroid plus retinal pigment epithelium taken from normal bovine eye balls and in human intraocular fluids from the eye balls in various ocular diseases (cataract, glaucoma, diabetes, intraocular tumors). Cathepsin A exhibited a pH optimum at 5.0 and showed the highest specificity towards N-Cbz-Phe-Ala as a substrate. In bovine ocular tissues high cathepsin A activity was found in the choroid plus retinal pigment epithelium and in cornea. The lens and the vitreous humor showed low enzyme activity and the aqueous humor none at all. In the human aqueous humor of the eye with cataract cathepsin A activity was more than three times higher then in the eye with choroid tumor. In human vitreous humor in absolute glaucoma the activity was twice as high as in melanoma and almost three times higher than in the case of lung metastatic tumor. Diabetes in glaucoma increased seven fold cathepsin A activity in the vitreous humor.

The variability and diagnostic usefulness of morphological features of metacercariae of two Diplostomum species, D. spathaceum and D. mergi, were studied on 104 and 85 specimens, respectively. Metacercariae were experimentally raised from cercariae in carp fry, Cyprinus carpio. Fourteen morphometric features and eight indices have been analysed. While no single variable could provide a classification with a reasonably small percentage of error, D. spathaceum and D. mergi have been separated with a misclassification rate less than 1% by applying a logistic regression model based on six significant variables (five metrical features and one index).

Mammalian lens contains Lewisx, sialyl-Lewisx and α-galactosyl epitopes in neolacto-series glycosphingolipids. The expression of these three epitopes is not observed in lens epithelial cells, but is immunohistochemically detected in the inner cortical fibers and the lens nucleus. In embryonic chick lens, sialyl-Lewisx-containing gangliosides were also detected in the transitional zone and elongating lens fibers. Thus, the Lewisx, sialyl-Lewisx and α- galactosyl epitopes may be associated with the differentiation and maturation of lens epithelial cells to lens fibers.
