After coursing through the cavernous sinus, the ICA pierces through the dural wall of the sinus to enter the subarachnoid space. It then gives off its first branch - the ophthalmic artery, which runs with the optic nerve and ophthalmic vein into the orbit. The ophthalmic artery passes beneath the optic nerve from lateral to medial.

Persistence of myelinated nerve fibers is a condition where myelin, which typically sheaths the optic nerve, extends abnormally into the retinal nerve fiber layer. This can appear as white, opaque patches on fundus examination, often with feathery edges. Myelinated nerve fibers can sometimes obscure underlying retinal structures and are generally benign but may be associated with visual field defects. #MyelinatedNerveFibers #RetinaImaging #Ophthalmology #retina #oftalmo #ophthalmology #oftalm...

This appears in Question 7.2 from the second paper of 2008 The discussion of visual pathway lesions lends itself especially well to explanation by means of a massive insane-looking eyeball diagram, which I have put together many years ago in med school. This summary page combines the insanity of colourful eyeball diagrams with the sober calm of tables. For a thorough exploration of bedside visual field testing technique, one can review Chapter 116 by R.H Spector from Clinical Methods (1990)…

The normal cup-to-disc ratio is less than 0.5. A large cup-to-disc ratio may imply glaucoma or other pathology. However, cupping by itself is not indicative of glaucoma. Rather, it is an increase in cupping as the patient ages that is an indicator for glaucoma. Glaucoma is the disease of the Optic nerve. Glaucoma damages your optic nerve causing blindness. Glaucoma is a leading cause of the blindness.
