[The factors affecting visual outcome in open globe injuries].

Background: To evaluate the factors affecting visual acuity in cases subjected to surgical repair due to open globe injury.

Methods: The records of the patients who have been subjected to emergency surgical repair due to open globe injury were examined retrospectively. From a total of 195 cases, 119 eyes of 119 cases who fulfilled the inclusion criteria were included into the study. Cases were examined in terms of age, gender, trauma type, localization, preoperative examination findings, the presence of additional surgical interventions and the findings in the last examination. Chi-square test and logistic regression analysis were used in statistical analysis.

Results: Original visual acuity (p=0.042), zone (p=0.001), trauma type (p=0.003), preoperative anterior chamber loss (p=0.005), existence of hyphema (p=0.001), vitreous prolapse (p=0.000) and posterior segment pathology development (p=0.000) influenced the visual outcome. In cases with grade 4 or grade 5 resulting visual acuity, statistically significant factors were determined as "existence of pathology in the posterior segment" (p=0.000, Odds ratio=12.397) and "total anterior chamber loss" (p=0.015, Odds ratio=4.661).

Conclusion: Changes occurring at the posterior segment pathology and anterior chamber loss are determinant in terms of resulting visual acuity. For this reason, ophthalmoscopy and ultrasonography that should not be omitted in the follow-up period for cases with a transparent media and with media opacity, respectively.
