Most Common Ocular Conditions

Common Conditions Affecting the Retina


Age Related Macular Degeneration (ARMD)


Definition

  • Chronic deterioration of the macula.

  • Central vision loss.


Prevalence

  • Leading cause of visual impairment in persons over 60.

  • The older you are the more likely you are to have ARMD.


Symptoms

  • Objects appearing smaller or farther away


Symptoms

  • Straight lines or faces appearing wavy

  • Doorways seeming crooked


Amsler Grid


  • Trouble in discerning colors; specifically dark ones from dark ones and light ones from light ones.

  • Slow recovery of visual function after exposure to bright light

  • A loss in contrast sensitivity.


Timing of Symptoms

  • Symptoms may come on so slowly that people don’t notice them.

    OR

  • They may come on quickly and dramatically.


Risk factors

  • No one knows why it happens, but risk factors include:

    • Obesity

    • High blood pressure

    • Smoking

    • High cholesterol

    • Family history

    • Gender – women more likely to get ARMD than men

    • Ethnicity – more likely to occur in Caucasians


Severity

  • Often causes loss of ability to read or do fine motor tasks, but persons with ARMD are typically able to continue to perform functional activities because the peripheral retina continues to function.


Wet Macular Degeneration

  • In the wet form, which is more severe, blood vessels grow up from the choroid behind the retina, and the retina can also become detached.


How is Wet ARMD treated?

  • Laser surgery

  • Cryro-therapy

  • Drugs


Dry Macular Degeneration

  • In the dry form, debris called drusen accumulate between the retina and the choroid, and the retina can become detached.


Nutrition

Some indication that the following vitamins and minerals are helpful to either avoid development of ARMD or slow down its progression

  • zinc,

  • lutein,

  • vitamins A, C and E
