Pyogenic Granuloma on Eyelid

This red mass is a pyogenic granuloma that has formed on the inner surface (the palpebral conjunctiva) of the eyelid. These growths can often form at the site of a chalazion, and will go away with steroids and tears. If they are large, however, like this one than they may warrant surgical removal.

Punctum: Eyelid Anatomy

The punctum (puncta) are tiny holes located in the eyelids near the bridge of the nose. Excess tears drain through the punctum, down the canalicular system into the lacrimal sac, then down into the nose. This explains why you get a runny nose when your eyes are watering.

Punctal Plugs in the eye

Punctal plugs are removable silicone plugs that are used to keep tears from draining too quickly out of the eye. They can be inserted by an eye doctor in the office, and are particularly helpful for patients suffering from dry eye. Sometimes used empiriclly after LASIK surgery.

Meibomian Gland Dysfunction

Here you can see an eye with prominant meibomian glands. These glands produce oil that is important to keep the tear film from evaporating too quickly. Some people have MGD (meibomian gland dysfunction) and these glands clog up and cause eye irritation (aka. blepharitis).

Chalazion of the eyelid

This video shows a chalazion, a non-infectious bump that can form on the eyelids, and is usually secondary to meibomian gland dysfunction. This particular chalazion is somewhat atypical in that it is draining profusely.

Ophthalmology Review: Are babies myopic or hyperopic?

Are babies more hyperopic? Yes, young children have small eyes, so that the image forms behind the retina. However, children are also able accomodate and bring the image forward to compensate for this. This is a review question I recorded for ophthobook.

Ophthalmology

Are children born near-sighted or far sighted? They are usually hyperopic, but have the ability to change the shape of their soft lens (accomodation) to bring the image onto the retina.

The Precise Neurological Exam

Ptosis is the lagging of an eyelid. It has 2 distinct etiologies. Sympathetics going to the eye innervate Muller's muscle, a small muscle that elevates the eyelid. The III cranial nerve also innervates a much larger muscle that elevates the eye lid: the levator palpebrae. Thus, disruption of either will cause ptosis. The ptosis from a III nerve palsy is of greater severity than the ptosis due to a lesion of the sympathetic pathway, due to the size of the muscles innervated. As an aside, the parasympathetics run with the III cranial nerve and are usually affected with an abnormal III cranial nerve.

Stanford University develops $90 iPhone accessory to replace ophthalmology kit costing tens of thousands

Researchers at Stanford University’s School of Medicine have developed two low-cost iPhone adapters that provide images of the eye that usually require specialist ophthalmology equipment costing tens of thousands of dollars. The university hopes that it will be useful both for primary care physicians in the U.S. as well as rural medical centres in developing countries.
