55-year-old white female with history of pathologic myopia+, lattice (laser), SB OU (1990s), and dislocated natural lenses OU that had been watched for years. In the fellow eye she developed phacolytic glaucoma and a PPV, PPL was performed. Plan for both eyes are monitoring. I wanted to get a good picture of her lens today with the optos machine, as the other pics had artifact from the lower lid. It worked out well to use a speculum in the left eye. Vision cc is 20/400 J1+ OD and 20/40 J2 OS; aphakic OU; vitreous clear OD; dislocated lens OS (see pic); retinas attached.

This image serial demonstrates a patient with simple ectopia lentis. Anterior segment photographs in the upper panel demonstrate nasally subluxated crystalline lenses. Widefield fundus photography shows a "pseudo-buckle" which is the result of an optical effect due to the lens subluxation (artifactual image enlargement). Also note the juvenile macular reflex in this young patient. Ectopia lentis can present isolated ("simple") or in combination with various systemic defects (Marfan's syndrome, Weil-Marchesani syndrome or Ehlers-Danlos syndrome to name a few). Isolated ectopia lentis can be hereditary and causative genes have been identified as ADAMTSL4 located on chromosome 4 and FBN1 gene located on chromosome 15. Defects in the genes cause weakness in the zonular fibers which can lead to lens dislocation. Lastly, various ocular disorders such as Aniridia, Axenfeld-Rieger, Pseudoexfoliation or Trauma may also result in lens dislocation or subluxation.

Inferior temporal retinoschisis extending posteriorly to arcade. The vertical cut shows more severe splitting inferiorly, with visibly attached outer layer. The “inverted V” shape of the inner layer on the left of the image is artifact, due to OCT-algorithm related inversion as this layer extends towards the vitreous.

Condition/keywords: bullous retinoschisis, inferotemporal retinoschisis, outer layer breaks
