Post-Cataract Day 3: Worsening Pain, Redness and Vision Loss
Post-Cataract Day 3: Worsening Pain, Redness and Vision Loss - Ophthalmology clinical simulation case. A 72-year-old pseudophakic female presents to the...
A 72-year-old pseudophakic female presents to the Emergency Department on postoperative day 3 following an uncomplicated right eye phacoemulsification with posterior chamber intraocular lens implantation, complaining of rapidly worsening right ocular pain, intense conjunctival injection, periocular swelling, and a marked subjective decrease in visual acuity in the operated eye.
Acute Resuscitation Milestones & Priorities
Clinical phases and key interventions encountered in this emergency module:
Triage, Isolation and Immediate Ophthalmologic Examination
Microbiologic Sampling and Intravitreal Antibiotic Injection
Adjunctive Systemic Therapy and IOP Management
Definitive Disposition: Pars Plana Vitrectomy Decision and Admission
High-Yield Clinical Pearls
Acute postoperative endophthalmitis typically presents 3 to 7 days after cataract surgery with the cardinal triad of ocular pain, hypopyon, and decreased vision; immediate recognition and treatment are essential because every hour of delay reduces the chance of visual recovery.
Initial empiric intravitreal therapy with vancomycin 1.0 mg and ceftazidime 2.25 mg provides reliable coverage of MRSA and gram-negative organisms including Pseudomonas aeruginosa.
The Endophthalmitis Vitrectomy Study established that eyes presenting with vision of light perception only benefit from immediate pars plana vitrectomy combined with intravitreal antibiotics, whereas hand motion or better vision is initially managed with vitreous tap and intravitreal injection alone.
Systemic antibiotics penetrate the blood-retinal barrier poorly and do not provide meaningful adjunctive benefit in exogenous bacterial endophthalmitis; intravitreal delivery is required.
Povidone-iodine 5% preparation of the conjunctival fornices and meticulous sterile technique during intravitreal injection are essential to prevent iatrogenic contamination of the vitreous cavity.
