Landolt Ring–Shaped Epithelial Keratopathy

Factors associated with surface epithelial keratopathy after optical penetrating keratoplasty

PURPOSE The aim of the study was to evaluate the various donor and recipient factors associated with short-term prevalence of surface epithelial keratopathy after optical penetrating keratoplasty (OPK). METHODS Preoperative and postoperative data of 91 eyes of 91 patients were reviewed retrospectively who had undergone OPK from March 2013 to February 2016. Donor and recipient data were analyz...

An Atlas of Spectrophotometric Landolt Standard Stars

We present CCD observations of 102 Landolt standard stars obtained with the R-C spectrograph on the CTIO 1.5 m telescope. Using stellar atmosphere models we have extended the flux points to our six spectrophotometric secondary standards, in both the blue and the red, allowing us to produce flux-calibrated spectra that span a wavelength range from 3050 Å to 1.1 μm. We find mean differences betwe...

Posterior polymorphous keratopathy.

Seven cases with posterior polymorphous changes of the cornea are reported. After clinical and pathological examination of the above cases, as well as a short review of the literature, the following points are made: (1) Some cases are congenital, being either familial or sporadic, but others are acquired. (2) The term "posterior polymorphous keratopathy" covers all the variants of the condition...

Actinomyces Infectious Crystalline Keratopathy

ber, similar to fungi. Recently, microsporidia have been phylogenetically shown to be fungi, and their tissue behavior akin to that of fungi would be expected. Our patient had clinical features of herpetic viral endotheliitis at the initial visit, which improved initially with antiviral treatment. There is a possibility that the patient may have had viral keratitis initially and then became sec...
