Glaucoma

Glaucoma is a group of progressive optic neuropathies characterized by the degeneration of retinal ganglion cells and their axons, leading to structural damage to the optic nerve head and corresponding functional loss of the visual field. It is a leading cause of irreversible blindness worldwide.

Etiology involves a combination of mechanical stress (elevated intraocular pressure - IOP) and vascular insufficiency affecting the optic nerve. Genetic predisposition, age-related tissue changes, and anatomical variations in the anterior chamber angle play significant roles.

The primary mechanism involves the impediment of aqueous humor outflow through the trabecular meshwork or the iris-lens interface. Sustained ocular hypertension induces axonal transport blockage, mitochondrial dysfunction, and apoptosis of retinal ganglion cells, leading to "cupping" of the optic disc.

Glaucoma affects approximately 80 million people globally. Prevalence increases significantly after age

1. POAG is more common in populations of African and Hispanic descent, while primary angle-closure glaucoma is more prevalent in Asian populations.

Age (>60), family history, elevated IOP, thin central corneal thickness, myopia, systemic hypertension, diabetes mellitus, and prolonged corticosteroid use.

A. Early Symptoms

• Usually asymptomatic


• Subtle contrast sensitivity loss B. Common Symptoms


• Gradual peripheral vision loss (tunnel vision)


• Halos around lights C. Advanced Symptoms


• Severe central vision loss


• Blindness D. Emergency Symptoms


• Sudden intense eye pain


• Headache


• Nausea and vomiting


• Blurred vision with colored halos

• Increased cup-to-disc ratio (>0.5)
• Elevated IOP via Goldmann applanation tonometry
• Narrowing of anterior chamber angle (gonioscopy)

A. Clinical Assessment: Slit-lamp biomicroscopy
B. Laboratory Testing: Rarely used for primary glaucoma
C. Imaging Studies: Optical Coherence Tomography (OCT)
D. Functional Tests: Standard Automated Perimetry (Visual Field Test)
E. Biopsy Findings: N/A
F. Genetic Testing: Primarily for juvenile-onset cases
G. Differential Diagnosis: Ocular hypertension, retinal detachment, optic neuritis

Test Name: Goldmann Applanation Tonometry
Type: Physical Measurement
Purpose: Measure IOP
Expected Findings: 10-21 mmHg
Interpretation: >21 mmHg indicates ocular hypertension.

Optical Coherence Tomography (OCT): Purpose: Assess retinal nerve fiber layer (RNFL) thickness; Findings: RNFL thinning; Importance: Monitors disease progression.

Ocular hypertension (high pressure without nerve damage), physiological cupping, optic nerve drusen.

Optic nerve atrophy, secondary cataracts (post-surgery), permanent blindness.

A. Lifestyle Modifications: Regular cardiovascular exercise
B. Preventive Measures: Regular eye exams
C. Medical Treatment:

• Prostaglandin analogs (Latanoprost)


• Beta-blockers (Timolol)


• Alpha-agonists (Brimonidine)


• Carbonic anhydrase inhibitors (Dorzolamide)

Prognosis is favorable with early detection and adherence to IOP-lowering therapy. Late-stage diagnosis often leads to permanent, non-reversible visual loss.

Annual comprehensive dilated eye exams for individuals over
40.
