Öğe Endogenous endophthalmitis due to Escherichia coli and management(Gazi Eye Foundation, 2016) Güçlü H.; Özal S.A.; Gürlü V.P.; Kinyas S.; Esgin H.Herein two cases with endogenous endophthalmitis and a subretinal abscess due to Escherischia coli (E. Coli) were described. First case was a sixty-eight-year-old male patient with endogenous E. coli endophthalmitis secondary to liver abscess and bronchobiliary fistula. Second case was a thirty-seven-year-old male patient with subretinal abscess caused by renal abscess. Endogenous bacterial endophthalmitis (EBE) and subretinal abscess are unusual, severe and vision threatening conditions that require close, frequent monitoring and should be considered in patients with systemic disorders. Systemic antibiotics, intravitreal antibiotics and vitrectomy have an important role in treatment. Vitrectomy helps to eliminate microorganisms, inflammatory cells, mediators, membranes from the vitreous and helps to get samples for microbiological examination in EBE. © 2016 Gazi Eye Foundation.

Patients analyzed for age, initial and final visual acuity, ophthalmoscopic findings, visual field, systolic, diastolic blood pressure and gestation week of the ocular findings. © 2017 Gazi Eye Foundation.

Material and Methods: Thirty eyes of thirty patients who had 23 g TSV surgery were included the study. All patients were examined at pre-operative, first week, first month and third month after operation. Corneal topographies were obtained and pre- and post-operative corneal astigmatism values were also measured. SIA was calculated by using pre- and postoperative corneal astigmatism values and axises with the method which developed by Jaffe and Clayman. Results: Post-operative mean SIA values were 0.67±0.34 (0.10-1.75) D, 0.4±0.23 (0.07-1.20) D and 0.22±0.16 (0.01-0.91) D at time points of first week, first month and third month, respectively. The decrease in SIA values through follow-up period was statistically significant (p<0.05) In the post-operative period, oblique astigmatism increased and irregular astigmatism decreased, but these changes were not statistically significant (p>0.05). Seventeen (81%) of 21 eyes with a shift to another meridian at post-operative first week returned normal values in time. Conclusion: SIA is a side-effect that overshadow the surgical success on visual acuity and quality. In our study it was found to be statistically significant decrease in the values of SIA after the post-operative first week. As a result, we consider that 23 g TSV provides better final refraction and visual acuity values for the patients. © 2016 Gazi Eye Foundation. All rights reserved.
