Normal Aging or Glaucoma?

As we get older, we lose 7000 retinal ganglion axons/year for 40% lost over a lifetime. This is .5% of your visual function lost every year!  Thinning of retinal nerve fiber layer surrounding our optic nerve and in the macula/retina is like thinning hair and receding gums with age.    In glaucoma, these ganglion cells areContinue reading “Normal Aging or Glaucoma?”

Posterior Synechia

This needs to be monitored carefully, as there is increased risk of glaucoma.   With the iris adhering to the lens, there is blockage of the aqueous humor flow from the posterior chamber to the anterior chamber. This blocked drainage can cause the intraocular pressure to increase, causing damage to the optic nerve.

When your pupil sticks to your lens…

A synechia happens when the iris adheres to either the cornea or lens.  Synechiae can be caused by ocular trauma, iritis or iridocyclitis and may lead to certain types of glaucoma.  Anterior synechia causes closed angle glaucoma, which means that the iris prevents proper drainage of the aqueous.   This raises the intraocular pressure. Posterior synechia also causeContinue reading “When your pupil sticks to your lens…”

When Glaucoma Runs in the Family

by Dr. Lisa Shin A 38 year old healthy male needed more contact lenses and came in for an eye examination.   Review of his medical history was normal, but he reported that his mother was currently being treated for glaucoma.  Corrected vision was 20/20 in both eyes.    The pressures in his eyes were measured toContinue reading “When Glaucoma Runs in the Family”
