Analysis of retinal detachment resulted from post-operative endophthalmitis treated with 23G pars Plana Vitrectomy

Characteristics and Risk Factors for Rhegmatogenous Retinal Detachment Related to Endophthalmitis

Purpose: To evaluate the risk factors for the development of concurrent or delayed-onset rhegmatogenous retinal detachment (RRD) related to endophthalmitis as well as the anatomic and visual outcomes with subsequent RRD repair. Methods: In this retrospective case study, a 2-tailed t test (continuous) and Fisher exact test were used to determine statistical significance of the observed findings. The relative risk (RR) and 95% CIs were calculated to assess statistical significance. Results: Of the 170 patients included, 22 were found to have a concurrent or subsequent RRD. Initial treatment with pars plana vitrectomy (PPV) (RR, 3.544; 95% CI, 1.650-7.614), aphakia (RR, 4.150; 95% CI, 1.434-12.011), endogenous endophthalmitis (RR, 2.684; 95% CI, 1.065-6.764), and posterior synechiae (RR, 3.026; 95% CI, 1.408-6.505) were statistically significant risk factors for RRD. Anatomically successful repair was achieved in 77.7% of patients. Conclusions: In addition to preexisting risk factors, the initial treatment of endophthalmitis may be a significant risk factor for RRD development, with a higher incidence of subsequent RRD in patients who have PPV as the initial treatment for endophthalmitis.

Lactobacillus acidophilus Endophthalmitis Postcataract Operation: A Case Report with a Literature Review

BACKGROUND

Lactobacillus acidophilus is usually considered nonpathogenic and widely distributed in the human gastrointestinal and vaginal tract. In rare cases, lactobacilli may cause eye infections.

CASE PRESENTATION

We report a 71-year-old man who experienced unexpected ocular pain and decreased visual acuity for one day after cataract surgery. He presented with obvious conjunctival and circumciliary congestion, corneal haze, anterior chamber cells, anterior chamber empyema, posterior corneal deposits, and pupil light reflection disappearance. This patient underwent the standard three-port 23-gauge pars plana vitrectomy and received the intravitreal perfusion of vancomycin at 1 mg/0.1 mL. The culture of the vitreous fluid produced Lactobacillus acidophilus.

CONCLUSION

Acute Lactobacillus acidophilus endophthalmitis can occur after cataract surgery, which should be taken into consideration.
