  • Abstract
  • Look Inside

We evaluated a series of 14 eyes, 13 patients, with pit in the optic disc. We used kinetic vitreous biomicroscopy with a preset lens attached to photoslit lamp. Secondary macular detachment was present in 10 eyes. In 5 of these 10 eyes, the canal of Cloquet showed characteristic features, showing condensed plicated membranes and abnormal inser-tion of the canal around the site of the pit in the optic disc. In one eye with macular detachment, a funnel-shaped posterior vitreous detachment was present with the residual vitreal adhesion to the pit. The other 4 eyes with macular detachment and 4 eyes without showed normal appearance of the vitreous except for occasional liquefaction of the gel.

The findings seemed to suggest that vitreous traction to the vitreous-pit adhesion plays a role in the development of macular detachment secondary to pit in the optic disc.
