Study Notes
Cataract Management
- Cataracts typically begin small with mild symptoms and progress over several years before requiring surgical management.
- Conservative management involves controlling risk factors, such as diabetes, smoking, steroid use, and UV exposure, to slow down cataract development.
Surgical Management
- Phacoemulsification with an intraocular lens implant is the most common surgical treatment for cataracts.
- Ocular biometry is conducted before surgery to measure corneal curvature and eye shape, allowing for selection of a suitable replacement lens.
- Surgical management is the definitive treatment for cataracts.
Complications
- Unmanaged cataracts can lead to loss of vision.
- Surgical complications include:
- Various types (not specified in the text)
Types of Cataracts
- Age-related cataracts are the most common type, with a multifactorial and not fully understood pathogenesis.
- Traumatic cataracts can occur following:
- Blunt and penetrating eye injuries
- Electrocution
- Chemical burns
- Radiation exposure
- Metabolic cataracts occur in:
- Uncontrolled diabetics
- Patients with galactosemia
- Patients with Wilson disease
- Patients with Myotonic dystrophy
