Anatomy & Body Systems
Affected Body Systems
- Ophthalmic System : Primary system - lens and ciliary body
- Neuromuscular System : Ciliary muscle innervation
- Cardiovascular System : Blood supply to ciliary body
- Endocrine System : Hormonal influences on lens metabolism
The Crystalline Lens:
- Located behind the iris and pupil
- Transparent, biconvex structure
- Composed of lens fibers (no blood vessels after development)
- Encased in elastic capsule
- Held in position by zonular fibers
- Changes shape for focusing
The Ciliary Body:
- Located behind the iris
- Contains ciliary muscles (smooth muscle)
- Produces aqueous humor
- Connected to lens by zonular fibers (suspensory ligaments)
The Zonular Fibers:
- Suspend the lens from ciliary body
- Attach around lens equator
- Tension controlled by ciliary muscle
Normal Accommodation:
- Looking at near object triggers convergence
- Ciliary muscle contracts
- Zonular fibers relax
- Lens becomes more convex (rounder)
- Light focuses on near retina
- Clear near vision achieved
Presbyopic Changes:
- Lens becomes less flexible with age
- Capsule loses elasticity
- Ciliary muscle function may decrease
- Lens cannot become sufficiently convex
- Near focus fails
- Need for reading assistance
Types & Classifications
Classification by Age of Onset
1. Early Presbyopia:
- Onset before age 40
- Often more severe
- May indicate other issues
2. Normal Presbyopia:
- Onset ages 40-45
- Progressive until age 60-65
3. Late Presbyopia:
- Onset after age 50
- Usually less severe
Classification by Severity
