Infectious Causes of Eye Disorders Quiz

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.

Medications Used in Ocular Disorders

• The slides detail various medications used in eye care, including antibiotics, antifungals, antivirals, anti-inflammatory drugs, dry eye treatments, glaucoma management, and VEGF inhibitors.
• Detailed considerations of usage and specific eye conditions for which the medication is used are discussed.
