[True or supposed bacterial endophthalmitis. Study of anatomo-functional outcome apropos of 32 cases].

PURPOSE: Vision prognostic study depending on the germs and the therapic performed in bacterial endophthalmitis.

METHODS

In a retrospective study over a period of 3 years (1991-1993), 32 cases of post surgery bacterian endophthalmitis were detected: 30 cases after cataract surgery (29 cases after extra capsular surgery and one case after intra capsular), one case after trabeculectomy and one case after keratoplasty.

RESULTS

A risk factor was evidenced in 15.6% of the cases. Endocular samples were done in 68.75% of the cases. The positive rate was 36.4% showing a Staphylococcus in 5 cases out of 8 (62,5%). In 37.5% of the cases an intraocular antibiotic injection was associated to the anterior chamber punction. 40% of the cases contaminated with Staphylococcus regained a visual acuity of more than 3/10. For the two cases where a Streptococcus was isolated an evisceration was necessary. Our results show that a higher visual acuity was obtained when a posterior vitrectomy was performed. When the posterior vitrectomy was associated with a corticoid therapy, the visual prognostic was better. Thus, 71% of these cases regained a visual acuity of more than 3/10.

CONCLUSION

Our results show that performing a posterior vitrectomy associated to a general corticotherapy within 48 hours from the bacterian endophthalmitis diagnosis would allow best vision improvement.
