Partial coloboma of the limbus is the term coined by Ascher[1] to a unique case described by him, in which the cornea appeared to extend into the sclera, in a small sector of the limbus, so that the area of canal of Schlemm could be faintly visualized. He found an almost similar case in literature described earlier by Kayser.

Reported here is an almost similar case seen by us.


  Case Report Top


VW, 17 year old female, came with the complaints of defective vision in the left eye. Examination showed that the lower part of the left cornea, from 5 O'clock to 8 O'clock appea­red to extend beyond the limbus into the sclera. This extension was crescentic shaped, the maxi­mum height of the crescent being about 12mm. This area was translucent and the corneoscleral junction was fairly well demarcated [Figure - 1]. Slit lamp examination showed a number of small blood vessels extending to where a normal limbus would be. Optical section showed that the abnormal area was flatter than the rest of the cornea. The area of corneoscleral trabeculae could easily be seen through the translucent tissue as a grey band. The canal of Schlemm could not be identified with any certainty. Gonioscopy showed a very prominent Schwalbe's line, to which were attached thick iris processes [Figure - 2]. These findings were seen only in the area of the abnormality. The fundus was normal. Corrected vision was 6/9. The other eye was normal. Examination of her only brother and parents showed no abnormality.
