Abstract
IntroductionRetinitis pigmentosa is clinically characterized by loss of predominantly rod photoreceptor function as well as loss of peripheral vision. The classic clinical triad is considered to be the presence of bone spicule pigmentation in the peripheral retina, arteriolar attenuation, and waxy disc pallor. Cataracts, most commonly of the posterior subcapsular type, are often found in all forms of retinitis pigmentosa. Ectopia lentis and lens dislocation are known risk factors for those with retinitis pigmentosa, presumably secondary to zonular fiber weakness and vitreous degeneration. The post-operative complication of lens dislocation following cataract extraction in patients with retinitis pigmentosa has also been documented.Case presentationWe report a case of severe capsular bag contraction with intraocular lens subluxation following cataract extraction in a 58-year-old Hispanic woman with retinitis pigmentosa.ConclusionPatients with retinitis pigmentosa undergoing cataract surgery should be notified of this potentially late complication of surgery.

Case presentation: We report a case of severe capsular bag contraction with intraocular lens subluxation following cataract extraction in a 58-year-old Hispanic woman with retinitis pigmentosa
We describe a spontaneous late posterior chamber intraocular lens subluxation secondary to severe capsular bag contraction in a patient with Retinitis pigmentosa (RP)
Summary
Retinitis pigmentosa (RP) is clinically characterized by loss of predominantly rod photoreceptor function as well as loss of peripheral vision. We describe a spontaneous late posterior chamber intraocular lens subluxation secondary to severe capsular bag contraction in a patient with RP. Case presentation A 58-year-old Hispanic woman presented to our clinic with blurred vision. The intraocular lens was well-positioned within the capsular bag. Three months after the surgery, she again presented to the clinic with blurry vision. She denied any history of trauma or fall. Fundus examination again revealed changes from RP that were stable compared to previous examination She was offered surgery, but declined it
