Retinal pallor

My optometrist photographs my retinas and sends them off to an ophthalmologist as a part of a yearly check up. My last check up was in mid-April, and I got a call in May.

The ophthalmologist has asked me to come in for an appointment on July 23 - something to do with "retinal pallor" in the photo of my left eye.

Dr. Google, and the EyeWiki say:

Optic nerve in the detection of glaucoma

Changes in the optic nerve in glaucoma are classically considered to be cupping and pallor of the disc. The term pallor is likely to be misinterpreted to mean generalized pallor of the optic nerve. The pallor of glaucomatous optic nerves relates to the increased visibility of the lamina cribosa as compared to the neuroretinal rim (containing the ganglion cells). As the rim thins from ganglion cell loss, the cup becomes larger and often deeper exposing the lamina with increased pallor of the cup. Pallor of the neuroretinal rim indicates previous insufficiency of the vascular supply of the optic nerve which is often unrelated to glaucoma.

The retinal ganglion cells coursing into the optic nerve are responsible for the appearance of the neuroretinal rim.

The decrease in vision from glaucoma is related to the loss of retinal ganglion cells. Elevated intraocular pressure is the greatest risk factor for development of ganglion cell loss. However there appear to be a number of different pathophysiologic mechanisms by which ganglion cell loss may occur. The optic nerve appearance often provides evidence of the presence and progression of glaucoma.

So, I'm a little worried! Glaucoma! It apparently does run in the family, on my mom's side.

Further details after the appointment, I guess. Wish me eyeball health.
