Filamentary K
Things that cause SLK
Thyroid
DED
CL
What does the course of SLK look like
Exacerbation and remission
What is SLK
Chronic inflammatory reaction associated with thyroid daises, DED, and/or CL wear. Most commonly in females with mean age of 50. Exact etiology unknown. Characterized by episodes of remission and exacerbation that eventually resolve over time
Signs of SLK
Bilateral, thickened, red, superior bulbar conjunctiva (most prominent at the limbus) and superior keratitis (SPK or filamentary). Tarsal conj has a velvety appearance secondary to diffuse papillary hypertrophy
Symptoms of SLK
Redness
FB sensation
Frequent blinking
Discharge is not common
Symptoms usually worse than signs
Types of adenovirus in eye
Acute non specific
PCF
EKC
Acute nonspecific adenovirus
Most common
Rare corneal involvement
Diffuse red eye, conj follicles in inferior fornices, tearing, chemosis, and mild discomfort.
PCF
Kids Swimming pool Low grade fever, sore throat Follicular conjunctivitis + low grade fever + sore throat Corneal involvement uncommon
EKC
Serotypes 8, 19, 37
Pain and corneal involvement at day 8
8 days later (day 16)-SEI/SPK, no longer contagious at this point
Preauricular lymphadenopathy
Possible pseudomembrane (remove, anesthetize, pull with jewelers)
Simple bacterial conjunctivitis
Children Acute onset Variable discharge Eyelids stuck together upon awakening Redness, burning, and FB sensation No PA or corneal involvement
Most common causes of bacterial conjunctivitis
Gram + (70% of cases)
Staph epi/aureus
Remaining cases typically from gram - rods including moraxella catarrhalis and H flu
Most common causative agents of bacterial conjunctivitis in kids
Strep pneumonia
H flu
Gonococcal conjunctivitis
Hyperacute Severe purulent discharge Conjunctival chemosis Pseudomembrane Papillary reaction Marked PA
Can invade and intact corneal epithelium
What is the only bacterial conjunctivitis that commonly presents with preauricular lymphadenopathy and pseudomembranes
N gonorrhea
Appearance of adult inclusion conjunctivitis
Acute conjunctivitis Unilateral giant follicles most concentrated in inferior fornices PA lymphadenopathy may be present Eyelids matted shut Minimal mucopurulent discharge
Adult inclusion conjunctivitis
Chlamydia (D-K)
Direct inoculation
Ocualr probs 5-14 days after inoculation
Usually have active urogenital infection
Symptoms of AIC
Chronic red eye that started several weeks to months prior
Can persist for 3-12 months if left untreated and eventually becomes bilateral
Corneal involvement in AIC
30-85% of patients and includes punctate keratitis, pannus and SEI (more peripheral in location compared to EKC)
Trachoma
Caused by chlamydia (A-C)
Most common preventable infectious blindness worldwide
Poor hygiene communities
Transmitted via direct contact of secretions but also through the common fly, fomites, or shared cosmetics
Most common in kids aged 1-5
Appearance of trachoma
Presents in early childhood with a mixed and often bialtera, follicular and papillary conjunctivitis of the superior tarsal conjunctiva
Mucopurulent discharge, PAL, and superior pannus
Progression through early adulthood resutls in Arlt lines (superior scarring), and herberts pits (depressions at the limbus). Progressive scarring of the tarsal conjunctiva leads to distortion of the eyelids and subsequent corneal ulceration due to trichiasis
What percent of cases of SLK are due to thyroid
50%
What tests should you order in someone with SLK
T3, T4, TSH
Most common etiologic agent for simple bacterial conjunctivitis
Staph aureus
