Abstract Details

Purpose:

Spontaneous lens dislocation is a rare pathology associated with multiple etiologies. Its causes include systemic and ophthalmological pathologies that explain the predisposition to this condition. In this work, the purpose is to describe a rare case of unilateral spontaneous lens dislocation that is not associated to the common causes described in the existing literature after an exhaustive, comprehensive and thorough etiological study, with good visual recovery after treatment.

Setting:

University General Hospital Gregorio Marañon, Madrid.

Methods:

A diagnostic study, treatment and complete follow-up was made in a patient who attended the emergency department with a posterior dislocation of unilateral spontaneous crystalline lens of the left eye to determine the possible etiologies associated. Imaging and laboratory test were made.

Results:

A 74-year-old man presented to the emergency department to be evaluated for sudden 3-hour decreased vision in the left eye. He has no medical history nor recent trauma. Visual acuity in the left eye was CF, with pinhole 1/8. On the examination, there was a posterior and inferior dislocation of the crystalline lens in the vitreous chamber with no vitritis. IOP 14 mm Hg. Inflammatory process, PEX, Marfan syndrome, Weil Marchesani, Anhiridia, Congenital Glaucoma, Megalocornea, Iris Coloboma, Ehler Danlos and hereditary Ectopia Lentis were discarded. He received surgery with PPV with Anterior chamber IOL. His visual acuity improved to 20/20. .

Conclusions:

The posterior dislocation of the lens has multiple causes, which is why an exhaustive and complete etiological diagnosis must be made. Among them, spontaneous dislocation is a rare entity that is usually associated with other ophthalmological and systemic diseases. The indicated treatment is PPV with IOL Implant in the anterior chamber whose visual prognosis is usually fair to good with an average visual acuity of 20/40 -20/50. This contrasts with the case presented, in which all the possible associated diseases described in the literature were ruled out, and in addition the visual result was excellent.
