Çukurova Üni. Tıp Fak. Göz Hast. ABD In order to evaluate the therapeutic effect of pars plana vitrectomy (PPV) in cases with exogenous endophthalmitis, we examined 28 cased who underwent PPV because of exogenous endophthalmitis in Çukurova University Medical Faculty Ophthalmology Department Retina Vitreus Unit. In 15 cases endophthalmitis occured posttraumatically, and in 13 cases postoperatively. We observed foreign body in 5 of the cases with posttraumatic endophthalmitis. Sistemic, topical, or subconjunctival antibiotic therapy was applied to 24 of these cases in different centers. We continued to administer antibiotic therapy and performed PPV to all cases. The study group was consisted of 21 male and 7 female with a mean age of 35.5±24.3 (4-73) years. The period between the initiation of symptoms and admission to the hospital was mean 7.3±5.6 (1-21) days, and the period between the diagnosis and vitrectomy was mean 3.9 ±2.8 (1-10) days. Visual outcome was not improved in 9 cases who were followed up 1 to 12 months (4.3±3.2) days. We observed improvement in visual acuity in 11 cases, and phitisis bulbi develeped in 3 cases. We could not evaluate the visual acuity of 5 cases who were uncooperative because of their young age.
In 10 cases corneal edema, in 4 cases retinal tears, in 3 cases intravitreal haemorrhage, in 1 case choroideal detachment, in 1 case retinal detachment, and in 1 case hyphema developed peroperatively. We observed retinal detachment in 5, phtisis bulbi in 3, and intravitreal haemorrhage in 2 cases as postoperative complications.
We can suggest that combination of PPV with intravitreal antibiotic therapy will have a beneficial effet on the prognosis of exogenous endophthalmitis, especially in cases with high posttraumatic endophthalmitis rate. Keywords : Exogenous endophtalmitis, pars plana vitrectomy
