The approach in patients with ocular hypertension or a family history of glaucoma or in patients with pseudoexfoliative syndrome, even without glaucoma, is more controversial. These patients may be a challenge not only in cataract cases, but also in presbyopia surgery Presbyopic Lens Exchange. There are no guidelines on this matter in the literature. Personally, I believe that these patients should undergo psychophysical and structural tests.

Since not all examinations can be performed, I suggest the following protocol:. It may seem strange not to include a contrast sensitivity study in this protocol. However, this is a non-standardized examination with a high number of false positives, and is of little use in individual cases.

If no abnormalities are detected with this protocol, I see no objection to implanting multifocal lenses in cataract surgery or refractive lensectomy. Nonetheless, aspherical, diffractive, pupil-independent? Several tests have been used to detect these lesions: a psychophysical tests , in which sensitivity thresholds to different stimuli are tested.

Which of these tests show nerve fibre damage in glaucoma earlier is still open to question. Why not share! Embed Size px. Start on. Show related SlideShares at end.

Incomplete dislocation in which the lens is still at least partially behind the iris but is tilted or displaced slightly in an anterior or posterior direction or perpendicular to optical axis. Dislocation : the entire lens may be in AC or may be in VC.

Generally upward and outward and occasionally into AC. Ocular abnormality was enlargement of the globe, presumably caused by scleral stretching, increased ocular axial length leads to stretching and rupture of the zonular fibers lead to dislocation Appears in the fourth and fifth decade of life Usually as upward dislocation Glaucoma results from the lens dislocation, also associated with surgical aphakia or AC anomaly.
