Nevus


Nevus

Statistics and Associations

  • Relatively low risk of melanoma; approximately 4 in 1000
  • Suspicious lesions include growth (after puberty), significant elevation, underlying fluid, overlying orange pigment, close proximity to optic nerve and resultant visual symptoms

Management

  • Photography for baseline
  • Suspicious Nevi should be followed with serial photography to detect any changes

Retinal Detachment


Retinal-Detachment
Statistics and Associations

  • Separation of retina from underlying tissues
  • Risk factors: lattice, nearsightedness, PVD, vitreous hemorrhage, retinal breaks (holes/tears), trauma
  • 30% association with lattice degeneration

Management

  • Surgical intervention
  • If macula is attached, emergent treatment is indicated (within 24 hours)
  • If macula is detached, urgent treatment is indicated (within 48 hours)

Lattice Degeneration


Lattice-Degeneration
Statistics and Associations

  • Thinning of peripheral retinal due to traction
  • Present in 10% of population
  • 25% develop holes in retina
  • More common in nearsighted people
  • 40% of retinal detachment patients also have lattice degeneration

Management

  • Monitor as indicated
  • Patient education regarding signs/symptoms of retinal detachment

Optic Atrophy


Optic-Atrophy
Statistics and Associations

  • Can be: traumatic, compressive (intraorbital/intracranial mass), hereditary (bilateral), toxic (bilateral), nutritional (bilateral), or secondary to various systemic situations/diseases
  • Vision variable (20/20 – 20/400)

Management

  • Consider neurology consultation

AION (Anterior Ischemic Optic Neuropathy)


AION-Anterior-Ischemic-Optic-Neuropathy
Statistics and Associations

  • Two forms: arteritic (emergency) and non-arteritic
  • Non-arteritic associated with high blood pressure (40%) and diabetes (20%)
  • Occurs in people older than 55 (older than 60 for arteritic)
  • Fellow eye involved in 25%-40% (non-arteritic)
  • Vision loss usually permanent

Management

  • Visual Field testing
  • Consider STAT lab testing (ESR, CRP, CBC), check blood pressure
  • Consider daily aspirin for non-arteritic AION

Optic Nerve Head Drusen


Optic Nerve Head Drusen
Statistics and Associations

  • Buried material within the substance of the optic nerve
  • 50% develop visual field defects
  • Visual field defects can mimic glaucomatous defects
  • Defects may change as the substance moves forward

Management

  • No treatment necessary
  • Monitor with routine visual fields to rule out glaucoma

Papilledema


Papilledema
Statistics and Associations

  • Bilateral swelling of the optic nerve due to increased intracranial pressure
  • Commonly associated with headaches, TVO’s, and pulsatile tinnitus
  • Typically caused by an intracranial mass, malignant hypertension, or idiopathic intracranial hypertension

Management

  • Visual field (enlarged blind spot), Optic nerve imaging (OCT)
  • Emergent MRI of brain and orbit, lumbar puncture
  • Check blood pressure

Toxoplasmosis


Toxoplasmosis
Statistics and Associations

  • Necrotizing inflammation of the retina caused by a parasite
  • Can be acquired (poorly cooked meat) or congenital

Management

  • Amsler grid for daily monitoring
  • No treatment necessary if inactive
  • Consider referral to retinal specialist if active

Histoplasmosis (POHS)


Histoplasmosis-POHS
Statistics and Associations

  • Scarring in the retina secondary to a previous fungal infection
  • Common in individuals raised on a farm (around chickens or other birds)
  • Endemic in Ohio and Mississippi river valleys
  • Fungus lies dormant with the potential to reactivate later
  • Possibility of new blood vessel growth under the retina at scar location in macula.

Management

  • No treatment necessary if inactive with no new blood vessel growth
  • Refer new blood vessel growth for treatment with anti-VEGF injection

Epiretinal Membrane/Macular Pucker


Epiretinal-Membrane-Macular-Pucker
Statistics and Associations

  • Cellular membrane growth/proliferation across retinal surface
  • Common risk factors: idiopathic, trauma, ocular surgery/laser treatment
  • Depending on location, can cause traction and wrinkling in macula (macular pucker) which can significantly decrease vision

Management

  • Amsler grid for daily monitoring
  • Surgical intervention if vision markedly reduced (20/60)
  • 75% show improvement in vision after surgery
