Visual acuity

with and without pinhole

Quantification – 20/30+ 2, 20/40 -2, CF at how many feet? HM
with or without direction at how many feet. Always pinhole even
if patient is CF.

History of trauma – dropped intraocular lens, dehiscence of
natural lens with high plus prescription (pinhole will clue you)
Workup

Autorefract, Topography, Refraction

Pachymetry – corneal edema, fuchs, pseudophakic or aphakic
bullous keratopathy

Large K ulcer – be prepared for md to request b scan to rule out
endophthalmitis

if patient is dry, place artificial tears during topography,
refraction, and autorefraction, ask patient to blink blink blink

Slit lamp photo (when requested)

Red or painful and watery eye or blurry vision with acute
presentation

?HSV ?HZV
Chemical burns, thermal injuries
History of HSV or HZV or brain tumor or facial trauma
(?trigeminal nerve involvment – schwannoma, acoustic neuroma,
memingioma, aneurysms, radiation therapy to route of CN5))
History of neurotrophic keratopathy in chart, multiple sclerosis
Zebras: Congenital -Ridley-Day syndrome, anhidrotic ectodermal
dysplasia, Moebius syndrome, Goldenhar syndrome, and
congenital corneal anaesthesia
Medications causing K anesthesia: timolol, betaxolol, trifluridine, s
Sulfacetamide, diclofenac, antipsychotics, antihistamines
Always check for apd as cn5 anesthesia + apd may suggest
intraconal nerve injury ? Tumor
Cornea ulcers, Epithelial Defects


As previously mentioned with regards to
proparacaine use
Post op day 1 DSAEK, no pressure should be
placed on globe, do not touch the eye or eyelid,
only visual acuity check (not an issue with
PKP)

Corneal edema
Goldmann is not as accurate as tonopen
 Corneal hysteresis altered, distorted meyers
 Tonopen contacts one spot
 Underestimate iop


Corneal calcification (band keratopathy)


Falsely elevated iop
In general goldmann is more accurate than
tonopen, except in above case

Swab and cultures brought to room prior to
physician arrival. Technician available to assist
with eyelid holding, labeling, and transport of
samples

Rooms stocked with fluoroscein and rose
bengal strips for vital staining
Rooms stocked with jewelers, bandage contact
lens, punctal plugs, 30 gauge needle
