The size of the cornea is important in the diagnosis of primary infantile glaucoma. Reference values regarding eyes of premature infants are scarce. Such data are of special importance in areas such as the Middle East where infantile glaucoma is common and often evident already at birth. The authors have measured the horizontal corneal diameter of the eyes of 127 premature Saudi infants with a ...

متن کاملRelationship between ciliary sulcus diameter and anterior chamber diameter and corneal diameter.
PURPOSE To evaluate the relationship between the horizontal ciliary sulcus diameter and anterior chamber diameter measured by 35 MHz ultrasound biomicroscopy (UBM) and the horizontal corneal diameter (white to white [WTW]) measured by scanning-slit topography and to assess the repeatability (intraexaminer difference) of the 2 methods.

متن کاملTotal Corneal Astigmatism Measurement.
We read with interest the article by Tonn et al. on corneal astigmatism. At the beginning of the article, the authors indicated that: ‘‘Scheimpflug tomographers provide a map of the anterior chamber and therefore a more accurate model of the cornea, its thickness, and posterior surface.’’ Since the anterior chamber is really a space, and not a structure, it is probably clearer to say that Schei...

deviations). This may be attributed to the accuracy to which corneal thickness can be read with the specular microscope. All three methods appeared to be equally precise from session to session (as indicated by the intercession standard deviations). On the other hand, the Mishima-Hedby attachment demonstrated a decreasing trend from session to session (as indicated by the analysis of variance r...
