EXAMINATION
Domain 1: Ocular Anatomy, Physiology, and Pathology
🟢 1. A 67-year-old patient presents with complaints of gradual painless vision
loss over 18 months. Fundus examination reveals drusen deposits in the macula
with associated retinal pigment epithelium changes. Which of the following best
describes the pathophysiological mechanism underlying this condition?
A. Accumulation of lipofuscin and extracellular debris between the retinal pigment
epithelium and Bruch's membrane
B. Progressive loss of retinal ganglion cells and their axons
C. Ischemic damage to the inner nuclear layer secondary to microvascular occlusion
D. Autoimmune destruction of photoreceptor outer segments
🔴 🔴 Correct Answer: A. Accumulation of lipofuscin and extracellular debris
between the retinal pigment epithelium and Bruch's membrane
,Rationale: This describes age-related macular degeneration (AMD), specifically the dry
(non-exudative) form. Drusen are deposits of lipofuscin, complement factors, and
extracellular debris that accumulate between the RPE and Bruch's membrane. Option B
describes glaucoma, Option C describes diabetic retinopathy, and Option D describes
autoimmune retinopathy. The optician should recognize AMD as a condition that may
warrant low-vision rehabilitation and enhanced contrast-enhancing lens options.
🟢 2. A patient undergoing treatment for open-angle glaucoma is prescribed
timolol maleate. The optician should be aware that this medication may cause
which of the following systemic side effects?
A. Mydriasis and cycloplegia
B. Bradycardia and bronchospasm
C. Increased salivation and lacrimation
D. Hypertension and tachycardia
🔴 🔴 Correct Answer: B. Bradycardia and bronchospasm
Rationale: Timolol is a non-selective beta-adrenergic antagonist. Even when applied
topically to the eye, systemic absorption through the nasolacrimal duct can cause
bradycardia, bronchospasm (particularly dangerous in asthmatic patients), and
hypotension. Opticians should advise patients to perform punctal occlusion after
instillation to minimize systemic absorption. Mydriasis/cycloplegia are effects of
anticholinergics, not beta-blockers.
, 🟢 3. During slit lamp examination with a cobalt blue filter and fluorescein, the
optician observes a dendritic pattern of corneal staining. This finding is most
consistent with:
A. Bacterial keratitis
B. Herpes simplex keratitis
C. Acanthamoeba keratitis
D. Fungal keratitis
🔴 🔴 Correct Answer: B. Herpes simplex keratitis
Rationale: Dendritic corneal staining is the classic hallmark of herpes simplex virus
(HSV) keratitis. The dendritic pattern represents viral replication within the corneal
epithelium. Acanthamoeba keratitis presents with severe pain disproportionate to
clinical findings and may show radial keratoneuritis. Bacterial and fungal keratitis
typically present with suppurative infiltrates. Opticians must recognize this pattern and
refer immediately, as topical corticosteroids are contraindicated.
🟢 4. A 52-year-old patient with a history of rheumatoid arthritis presents with
complaints of dry eye symptoms. Schirmer's test without anesthesia reveals 4 mm
of wetting after 5 minutes. This finding is most consistent with:
A. Normal tear production
B. Mild aqueous tear deficiency
C. Severe aqueous tear deficiency
D. Lipid layer deficiency
🔴 🔴 Correct Answer: C. Severe aqueous tear deficiency
Rationale: Schirmer's test without anesthesia measures total tear secretion (reflex plus
basal). Normal values are >15 mm of wetting in 5 minutes. Values of 5–10 mm indicate
