What is pigment dispersion syndrome?
Pigment-dispersion syndrome is an eye disorder that occurs when pigment granules that normally adhere to the back of the iris (the colored part of the eye) flake off into the clear fluid produced by the eye (aqueous humor).
Does pigment dispersion syndrome improve with age?
The onset of pigment dispersion syndrome, which is an autosomal dominant disorder, typically occurs when patients are in their early 20s, but the condition begins to regress with increasing age, enlargement of the lens, and the loss of accommodation due to the onset of presbyopia.
What is Krukenberg spindle?
Krukenberg’s spindle represents melanin pigment forming a vertical line on the posterior central cornea in contrast to other melanin pigment depositions that tend to be more circular or diffuse in distribution (see Fig. 16.21).
Can you go blind from pigmentary glaucoma?
Blindness due to pigmentary glaucoma is rare. In a study of 113 patients with PDS and pigmentary glaucoma, three eyes in two patients were blind. Progression of the disease, however, is common.
Can you get Lasik with pigment dispersion syndrome?
Conclusions: Corneal findings of PDS do not appear to affect the intraoperative or postoperative outcomes of LASIK. However, patients who have PDS in the context of glaucoma and therapy with an intraocular-pressure-lowering agent may experience delayed healing and a less predictable visual outcome.
What causes pigment loss in eyes?
Pigment Dispersion Syndrome is an uncommon condition. Most commonly affected are nearsighted males between the ages of 30 and 50. It is also more common in Europeans. The cause of pigment dispersion is a mechanical rubbing between two ocular structures: the IRIS and ZONULES.
Is Krukenberg tumor curable?
Abstract: Krukenberg tumor (KT) is a rare metastatic ovarian tumor originating from other malignancy. Although there is neither randomized trial nor standard treatment guidelines, review studies show that cytoreductive surgery, chemotherapy and radiotherapy improve survival for patients with KT.
