According to the Endophthalmitis Vitrectomy Study (EVS), immediate pars plana vitrectomy (PPV) is superior to vitreous tap/biopsy in endophthalmitis ONLY when the presenting visual acuity is:
- A Hand movements or better
- B Counting fingers or better
- C Light perception only ✓
- D No light perception
Correct answer: C. Light perception only
Explanation
The EVS found that in acute post-cataract surgery endophthalmitis, immediate PPV was superior to vitreous tap/biopsy only in patients presenting with light perception (LP) only as visual acuity; in these patients, 3-line BCVA improvement was significantly better after PPV. In patients with hand movements or better vision, PPV and tap/biopsy yielded equivalent outcomes. All patients received intravitreal antibiotics (vancomycin + amikacin).
