ECTOPIA LENTIS

1. Acquired

2. Isolated familial ectopia lentis

3. Associated with systemic syndromes

  • Marfan syndrome
  • Weill-Marchesani syndrome
  • Homocystinuria

4. Treatment options

slide2

Acquired ectopia lentis

Trauma

Stretched zonules

  • Buphthalmos
  • Megalocornea

Anterior uveal tumours

Degenerate eye

slide3

Isolated familial ectopia lentis

Autosomal recessive

Pupil may be normal

Pupil may be displaced in opposite

direction (ectopia lentis et pupillae)

slide4

Autosomal dominant

Systemic features of Marfan syndrome

  • Arachnodactyly
  • Limb-trunk disproportion
  • Aortic dilatation, dissection
  • and regurgitation
  • Pectus excavatum
  • High-arched palate
  • Mitral valve prolapse
slide5

Ocular features of Marfan syndrome

Lens

Retinal detachment

  • Lattice degeneration
  • Axial myopia
  • Upward subluxation
  • Zonule usually intact

Angle anomaly and

glaucoma

Cornea plana

Blue sclera

slide6

Autosomal recessive

Weill-Marchesani syndrome

Systemic features

Ocular features

  • Microspherophakia
  • Short stature
  • Usually anterior lens subluxation
  • Short stubby fingers (brachydactyly)
  • Angle anomaly and glaucoma
  • Mental handicap
slide7

Homocystinuria

  • Autosomal recessive
  • Defect in cystathio beta-synthase

Systemic features

Ocular features

  • Downward lens subluxation
  • Malar flush and fine, fair hair
  • Marfanoid habaitus
  • Disintegration of zonule
  • Increased platelet stickiness
  • Mental handicap
slide8

Treatment Options for Ectopia Lentis

1. Spectacle correction

  • For induced astigmatism
  • For aphakic portion

2. Nd:YAG laser zonulysisto displace lens out of visual axis

3. Surgical removal

  • Associated cataract
  • Lens-induced glaucoma
  • Endothelial touch
  • When other methods are inappropriate
