Study Notes
Red Eye Syndrome
- Most common chief complaint in ophthalmology.
- Commonly referred to as "sore eyes" or conjunctivitis.
- Differential diagnoses include uveitis, keratitis, and glaucoma.
Glaucoma
- Acute angle closure glaucoma is critical for preserving vision.
- Symptoms include unilateral severe headache, nausea, vomiting, sudden visual loss, and seeing halos.
- Physical examination reveals hazy cornea, shallow anterior chamber, and increased intraocular pressure (IOP).
- Treatment options: beta blockers, ACE inhibitors, laser iridotomy, trabeculoplasty, and filtering surgery.
Conjunctivitis
- Inflammation of the conjunctiva classified as viral (watery), allergic (mucinous), or bacterial (purulent).
- Severe bacterial infections require gram stain and culture.
- Viral infections often present with pre-auricular lymphadenopathy; bacterial infections may show post-auricular and submandibular lymphadenopathy.
- Treatment involves topical antibiotics.
Uveitis
- Inflammatory condition involving the uveal tract (iris, ciliary body, and choroid).
- Symptoms include conjunctival, episcleral, and scleral hyperemia, primarily at the circumlimbal area.
- Other signs: blurred vision, presence of flares and cells in the anterior chamber, photophobia, and eye pain.
- Treatment typically includes steroids and cycloplegic agents.
Keratitis
- Inflammation of the cornea leading to disruption of the epithelial layer.
- May appear as a hazy cornea; vision loss is significant if central axis is affected.
- Associated with photophobia due to ciliary spasm.
- Treatments include cycloplegics and steroids (avoid steroids with epithelial defects).
Corneal Scarring and Pterygium
- Pterygium characterized by elastotic degeneration of the conjunctiva; presents as a triangular, vascular mass encroaching the cornea.
- Common in individuals exposed to chronic UV light and dryness (outdoorsmen, pigmented races).
- Treatment: surgical excision.
Pinguecula and Hordeolum
- Pinguecula: a pterygium not encroaching on the cornea.
- Hordeolum (stye) involves infection of a hair follicle.
- Treatment for hordeolum includes incision and curettage, along with topical antibiotics.
Chalazion and Foreign Body
- Chalazion involves chronic inflammation of the meibomian gland; treated with incision and curettage.
- Foreign body injuries (e.g., projectile trauma, welding) require removal along with rust ring removal and topical antibiotics.
Dry Eyes
- Often associated with aging and autoimmune diseases; diagnosed with Schirmer’s test.
- Treatment includes artificial tears and lubricants.
Tearing
- Excessive lacrimation due to autoimmune response or obstruction in the lacrimal apparatus.
- Jones test is used for diagnosis; treatment includes irrigation and DCR (dacryocystorhinostomy).
Blepharitis
- Infection of the lid margins results in dandruff-like flakes and matting of eyelashes.
- Treated with antibiotic ointments and lid scrubs.
Nevus and Xanthelasma
- Nevus refers to a benign accumulation of pigment in any part of the eye that may only need observation.
- Xanthelasma appears as yellow-brown pigment on eyelids, linked to hyperlipidemia. No treatment necessary but requires referral to an internist.
Lid Wart, Entropion, and Ectropion
- Lid wart (verruca vulgaris) treated with excision or cautery.
- Entropion involves inward eyelid turning, while ectropion refers to outward turning; both require surgical repair.
Trichiasis, Ptosis, and Lagophthalmos
- Trichiasis entails misdirection of eyelashes potentially harming the cornea; treated by pulling off hairs or using cryotherapy.
- Ptosis is the drooping of the upper eyelid needing surgical repair.
- Lagophthalmos is the inability of eyelids to close, potentially causing exposure keratitis; seen in Bell’s palsy; treated with tear lubrication and surgery if necessary.
