Study Notes
Eye Balls (and Friends) - Clinical Med: Ocular 1&2
- The presentation covers various ocular conditions, including disorders of the eyelids, lacrimal system, conjunctiva, cornea, and associated treatments.
- The date of the presentation is January 27, 2025, and the presenter is Joseph D. Klauer OD.
- Numerous images demonstrating different eye conditions and anatomical structures are included in the presentation.
- The presentation includes a variety of topics and subtopics, including specific disorders and anatomical structures of the eye.
Lid Disorders
- Blepharitis: inflammation of the eyelids, presenting with symptoms like burning, itching, tearing, and crusting, especially in the morning.
- Hordeolum: acute infection of eyelid glands, appearing as a localized red, swollen, and tender area. Can be internal (meibomian gland abscess) or external (stye).
- Chalazion: common granulomatous inflammation of a meibomian gland. Often presenting as a hard, nontender swelling on the eyelid with adjacent conjunctiva redness.
- Ectropion: outward turning of lower eyelid due to loss of muscle tone in the orbicularis oculi. Associated with advanced age, mechanical factors (tumor), or cicatricial conditions (scar tissue/trauma, chemical burns).
- Entropion: inverted turning of the eyelid against the globe, commonly associated with involutional changes, cicatricial factors (trachoma, SJ syndrome), or trichiasis (eyelashes growing posteriorly).
- Lumps and Bumps: Eyelid Cysts, Milia, Dermoid Cyst, Sebaceous Cyst are discussed for their characteristics, common locations, and treatments.
Lacrimal Disorders
- Dacryocystitis: infection of the lacrimal sac, often unilateral with pain, crusting, and excessive tearing, a prominent edema, and tenderness beneath the medial canthal tendon.
- Dacryoadenitis: inflammation of the lacrimal gland.
- Jones I & II Testing: tests for the patency of the lacrimal drainage system.
Refractive/Binocular Status
- Nystagmus
- Strabismus
- Amblyopia
- Myopia
Corneal Disorders
- Infectious Keratitis: bacterial infection often associated with pseudomonas, with symptoms of intense pain, red eye, photophobia, and decreased vision.
- Viral Keratitis: herpes simplex keratitis, with branching corneal lesions, visible on fluorescein staining.
- Corneal Ulceration: an infiltrate within the cornea in addition to an overlying epithelium defect, involving pain, photophobia, tearing, and reduced vision.
- Dry Eye Disease: characterized by lack of tear production, abnormalities in tear film stability and volume, dryness, redness, foreign body sensation, as well as variable vision, and significant discomfort.
