Ophthalmology Quiz: Eye Disorders and Treatments

Band Shaped Keratopathy

• Commonly caused by calcium deposits in the cornea, often associated with chronic conditions like chronic keratitis.

Treatment for Photophthalmia

• Recommended treatment includes the use of topical lubricants, sunglasses to protect from light, and analgesics for discomfort.

Dense Scar and Iris Incarceration

• Characterized by a condition known as "corneal leukoma," leading to severe vision impairment and distortion.

Fluorescein Staining in Corneal Ulcer

• Fluorescein staining appears bright green in the presence of a corneal ulcer, indicating areas of epithelial loss.

Drug Indicated for Corneal Ulcer

• Regardless of cause, topical antibiotics are always indicated to prevent bacterial superinfection in corneal ulcers.

Diminished Corneal Sensations

• Diminished corneal sensations commonly occur in conditions like herpes simplex keratitis or after trigeminal nerve damage.

Defective Vision in a 12-Year-Old Boy

• Long-term treatment for spring catarrh may lead to defective vision due to potential complications such as keratoconus or cataracts.

Diagnosis for Young Child with Fever and Conjunctivitis

• Likely diagnosed with viral conjunctivitis, presenting with lacrimation, follicles in the conjunctiva, and tender preauricular lymphadenopathy.

Contraindications for Eye Bandage

• Bandaging the eye is contraindicated in cases of perforated cornea, as it may lead to complications.

Condition in a 10-Year-Old Boy

• Most probable condition is vernal keratoconjunctivitis characterized by itching, mucous nodules on the limbus, and ropy mucopurulent discharge.

Viral Epidemic Kerato-conjunctivitis

• Characteristically presents with redness, watery discharge, and conjunctival follicles.

Corneal Herbert's Rosettes

• Found in patients with pollen-associated eye conditions, usually indicating an allergic response.

Conjunctival Swab Findings

• A swab from a patient with lid maceration and conjunctival redness may show bacterial growth, indicating bacterial conjunctivitis.

Term for Dense Scar of Cornea

• The condition is referred to as "corneal leukoma."

Recurring Bilateral Conjunctivitis

• Recurring conjunctivitis in young boys during hot weather may suggest allergic conjunctivitis or vernal keratoconjunctivitis.

Organisms Penetrating Corneal Epithelium

• Certain organisms such as Neisseria gonorrhoeae can penetrate intact corneal epithelium, leading to infection.

Painful, Tender, Non-Itchy Conjunctival Redness

• Could be due to conditions like conjunctivitis, keratitis, or a foreign body causing localized irritation.

Fifth Nerve Palsy Effects

• May lead to decreased corneal sensation and inability to blink properly, increasing the risk of corneal damage.

Topical Steroids in Viral Corneal Ulcer

• Their use is contraindicated due to the risk of worsening the infection or causing corneal perforation.

Sure Diagnostic Sign of Corneal Ulcer

• A definitive sign of corneal ulcer includes the presence of epithelial defects along with pain and redness.

Tranta's Spots

• Noticed in allergic eye conditions, particularly in vernal keratoconjunctivitis, indicative of chronic inflammation.

Cause of Defective Vision in Long-Term Treatment

• The likely cause in a 12-year-old undergoing treatment for spring catarrh could be due to the development of complications like keratoconus.
