A Report on Ectopia Lentis Biology Essay
Ectopia lentis is characterized by dislocation of the lens due to partial or complete disruption of the zonular fibers. Several genetic causes of ectopia lentis have been identified and inheritance can be autosomal dominant or autosomal recessive. Ectopia lentis can occur as an isolated defect or be syndromic. Congenital aniridia with ectopia lentis and unilateral buphthalmos: an unusual presentation. BMJ Case Rep. 2021, 14 8 e244000. doi: 10.1136 bcr-2021-244000. Indeed, ectopia lentis is one of the findings used to help identify patients with Marfan syndrome. the acquired causes of ectopia lentis and iridodonesis may be nutritional disorders such as hyperhomocysteinemia. Suggest that vitamin C deficiency may be another acquired collagen disorder that can cause ectopia lentis. The right eye ultimately underwent prophylactic lensectomy and aphakic correction. Conclusions: This report presents a unique presentation of isolated ectopia lentis with anterior lens dislocation and pupillary block and illustrates the role of smartphone photography in assisting with the triage of ocular emergencies. However, here we report spherophakia as a new ophthalmological finding in SWS · year-old woman who had previously been diagnosed with SWS, presented to the outpatient clinic complaining of right-sided decreased visual acuity and pain after a fall. Phenotypically, the patient had a PWS around V and involvement of both eyelids. In this report, we describe a case of ectopia lentis complicated by partial anterior lens dislocation with pupillary block. Case Presentation A healthy four-year-old boy was referred by an outside ophthalmologist to the Department of Pediatric Ophthalmology at the Wilmer Eye Institute, Baltimore, Maryland for bilateral partial lens dislocation. Citation, DOI, disclosures and article details. Ectopia lentis refers to subluxation or dislocation of the eye lens due to dysfunction or disruption of zonular fibers. This is usually the result of trauma. The most common atraumatic etiologies are Marfan syndrome and homocystinuria. The main objective of this report is to describe a case of ectopia lentis et pupillae syndrome, highlighting the secondary ocular complications and their differential diagnoses in a year-old male. Ectopia lentis usually happens after trauma or injury damages your eye. Children are sometimes born with ectopia lentis, a congenital ectopia lentis caused by a genetic mutation. Ectopia lentis that affects only one of your eyes is called isolated ectopia lentis. Ectopia lentis affecting both eyes at the same time is bilateral ectopia. Introduction. Sturge-Weber syndrome SWS is a rare sporadic neurocutaneous disorder caused by a somatic activating mutation in GNAQ, of cases 1 SWS births, and characterized by a unilateral facial capillary malformation, port wine stain, PWS of the skin in the ophthalmic territory , pedigrees and ocular phenotypes of two families of Marfan syndrome with ectopia lentis EL. Family tree overviews of, a and, b. The dark squares male and circles female indicate this. To report a small series of pediatric patients with ectopia lentis who underwent limbal approach lensectomy and vitrectomy and scleral-fixed intraocular lens implantation and to review the findings. To report the ultrasound biomicroscopy UBM and surgical findings in an individual with a syndrome of ectopia lentis, spontaneous filter vesicles and craniofacial dysmorphism Traboulsi syndrome. Congenital ectopia lentis EL is a rare but serious disease that manifests as. 2,
