Purpose. To evaluate visual outcomes and identify prognostic factors after pars plana vitrectomy (PPV) surgery for traumatic endophthalmitis. Methods. Medical records of 121 consecutive patients (121 eyes) diagnosed with traumatic endophthalmitis that had undergone pars plana vitrectomy were retrospectively reviewed. Results. 121 patients, aged from 6 to 71 years, all underwent PPV surgery. 113 cases had improved best corrected visual acuity (BCVA) after surgery and 60% of them obtained BCVA better than fingers counting (FC). Good final visual prognosis was significantly associated with time between trauma and initial treatment less than 12 hrs (40% versus 98%; P<0.001), time between trauma and PPV treatment less than 24 hrs (62% versus 98%; P<0.001), laceration length less than 10 mm (63% versus 96%; P<0.001), and presenting VA better than LP (42% versus 96%; P<0.001), while gender, type of laceration, presence of IOFB or retinal detachment, and the use of silicone oil tamponade were not significant factors resulting in better BCVA. Bacteria were identified in 43.8% of specimens and most of the microorganisms were identified as nonvirulent ones. Conclusions. Pars plana vitrectomy surgery was preferred as a primary treatment option for traumatic endophthalmitis. A good final visual prognosis was significantly associated with timely treatment, prompt vitrectomy surgery, shorter length of laceration, and better presenting visual acuity.

Abstract Background The aim of this retrospective study was to evaluate commonly used clinical and OCT-morphological parameters, including perifoveal pseudocysts, as prognostic factors for postoperative outcome after macular hole surgery in a retinal referral clinic in North Rhine-Westphalia, Germany. Methods and material This was a retrospective analysis of all patients who underwent surgery because of idiopathic MH between 2011 and 2017 in Augenklinik Tausendfensterhaus, Duisburg, Germany. Statistical evaluation of clinical and OCT-based parameters, including the areas of intraretinal pseudocysts, was conducted. The main statistical outcomes were surgical success and visual acuity. Only parameters with a highly significant correlation to the outcome parameters (postoperative visual acuity (VA); surgical success) in univariate analysis were entered in linear and logistic regression analyses. Results A total of 189 eyes of 178 patients (71.4% female; mean age 67.5 ± 8.2 a) who underwent surgery because of MH were included. The overall closure rate was 86.8%. The mean best corrected VA increased from 0.7 ± 0.3 logMAR before surgery to 0.5 ± 0.3 logMAR (p < 0.0001). While several clinical and OCT-based parameters as well as calculated indices showed a significant correlation with the outcome measures, the regression analysis showed that the minimum linear diameter was the only parameter that both predicted surgical success (p = 0.015) and was correlated with postoperative VA (p < 0.001). Conclusion The minimum linear diameter serves as an easily assessed prognostic factor with the best predictive properties. This result is of great importance for clinical practice, as it simplifies the postsurgical prognosis.

AIM: To identify the clinical features and treatment outcomes of endogenous Klebsiella pneumoniae endophthalmitis and investigate prognostic factors of poor visual outcome. METHODS: The clinical records of all patients diagnosed with endogenous Klebsiella endophthalmitis between January 2007 to December 2018 in Prince of Wales Hospital, Hong Kong, China were retrospectively reviewed. Thorough ophthalmological examination findings were recorded in the case note, including visual acuity testing, slit-lamp examination, indirect ophthalmoscopy and B-scan ultrasonography if media opacity precluded fundus viewing. RESULTS: A total of 18 eyes in 14 patients were identified. Bilateral involvement was noted in 4 patients (28.6%). Hepatobiliary sepsis was the source in 9 patients (64.3%). Culture of intraocular fluid was positive in 5 out of 18 eyes (27.8%). Mortality was noted in 2 patients (14.3%). Mean final visual acuity was 20/1500. Six out of 16 eyes had total loss of sight (37.5%) and 3 eyes required evisceration (18.8%). Multivariate linear regression revealed poor presenting visual acuity (P=0.031) and lack of fundus view due to vitritis (P=0.02) as prognostic factors of poor visual outcome. CONCLUSION: Visual outcome of endogenous Klebsiella endophthalmitis is poor. Poor presenting visual acuity and lack of fundus view predict poor visual outcome. High index of suspicion for endophthalmitis is important in Klebsiella sepsis patients with complaints of ocular symptoms. Ophthalmological screening is recommended in non-communicable patients with Klebsiella sepsis.

Abstract BackgroundTo identify prognostic factors determining final visual outcome following open globe injuries.MethodsRetrospective case series of patients presenting to Westmead Hospital, Sydney, Australia with open globe injuries from 1st January 2005 to 31st December 2017. Data collected included demographic information, ocular injury details, management and initial and final visual acuities.ResultsA total of 104 cases were identified. Predictors of poor final visual outcomes included poor presenting visual acuity (p < 0.001), globe rupture (p < 0.001), retinal detachment (p < 0.001), Zone III wounds (p < 0.001), hyphema (p=0.003), lens expulsion (p = 0.003) and vitreous hemorrhage (p < 0.001). Multivariate analysis demonstrated presenting visual acuity (p < 0.001), globe rupture (p = 0.013) and retinal detachment (p = 0.011) as being statistically significant for predicting poor visual outcomes. The presence of lid laceration (p = 0.197) and uveal prolapse (p = 0.667) were not significantly associated with the final visual acuity. ConclusionsPoor presenting visual acuity, globe rupture and retinal detachment are the most important prognostic factors determining final visual acuity following open globe injury.

Abstract Background: To investigate the natural course and prognostic factors of ethambutol toxic optic neuropathy (ETON).Methods: Medical charts of 87 patients diagnosed with ETON were reviewed retrospectively, and the visual acuity and history of ethambutol medication were analyzed. Based on the final visual acuity, patients were divided into two groups: recovery and no-recovery groups. We investigated the prognostic factors, including the sex, age, duration of medication, initial visual acuity, and systemic diseases (diabetes mellitus, hypertension, renal disorders, etc.). Results: In this study, 37 men and 50 women, with ages ranging from 22 to 91 years, were included. Although a poor initial visual acuity was noted in the old patients, a short duration of medication had a weak negative correlation with the initial visual acuity. Follow-up of over 1 year could be performed for 28 out of 87 patients, including nine men and 19 women, with a mean age of 70.0 ± 8.2 years. Ten eyes of seven (25%) patients, including three men and four women, did not recover vision after discontinuation of ethambutol. Patients were significantly older in the no-recovery group than in the recovery group (73.9 ± 8.3 and 68.7 ± 8.1 years, respectively). The poor initial visual acuity and presence of systemic diseases affected the prognosis of ETON. Conclusion: Three-fourth of patients with ETON had visual recovery after discontinuation of ethambutol. High-risk patients with poor prognostic factors, including old age, presence of systemic diseases, and poor initial visual acuity, should be screened in early stages of ETON.

Purpose. The purpose of this study is to find prognostic factors associated with low visual acuity in patients experiencing vitreous loss during cataract surgery. Methods. A retrospective, noncomparative, interventional, case study of patients experiencing vitreous loss during cataract surgery. Data collected included demographics, best corrected visual acuity (BCVA), axial length (AL), presence of ocular comorbidity affecting central vision, timing of intraocular lens (IOL) implantation, position of the implanted lens, and the presence of corneal sutures. Low visual outcome was defined as BCVA < 20/40. Results. Overall, 179 patients (60.3% males) with a mean age of 73 ± 12 years and axial length of 23.5 ± 1.3 mm with a mean follow-up of 12 ± 13 months were included. In multivariable logistic regression analysis, low visual outcome was independently associated with persisting postoperative complications (OR 6.25, 95% CI 1.378–30.9), preexisting ocular comorbidities (OR 4.45, 95% CI 1.1–18.00), and secondary intraocular lens (IOL) implant (OR 10.36, 95% CI 1.8–60.00). Conversely, pars plana vitrectomy (PPV) for dislocated fragments of lens material, age > 70 years, gender, axial length, degree of surgeon, corneal suturing, and anterior chamber lens implantation were not found to have significant associations with low visual outcomes ( P > 0.05 ). Conclusions. Low visual outcome after vitreous loss during cataract surgery was associated with ocular comorbidities, secondary IOL implantation, development of cystoid macular edema, and additional surgical complications.

Aim. To describe epidemiologic and clinical characteristics and prognostic factors influencing visual outcome after intraocular foreign bodies (IOFBs) injury. Methods. Medical records of 370 patients (373 eyes) with IOFBs were reviewed to identify the factors influencing visual acuity by univariate and multivariate analyses. Results. The majority of patients (97.0%) were men, with a mean age of 38.1 years. The most common cause of ocular injury was hammering (52.6%); magnetic IOFBs occurred in 84.7% of these cases. Factors associated with poor visual outcome (defined as <1.3 logMAR) included the following: age ≥50 years (P=0.046); worse presenting visual acuity (P<0.001); complications of retinal breaks (P=0.006) and endophthalmitis (P=0.032); vitrectomy (P=0.035); and intraocular C3F8 gas tamponade (P=0.038). Excellent visual outcome (defined as ≥0.5 logMAR) was associated with age <50 years (P=0.003); better presenting visual acuity (PVA) (P<0.001); wound length <4 mm (P=0.005); absence of vitreous hemorrhage (P=0.026) and retinal breaks (P<0.001); nonvitrectomy surgery (P=0.043); and use of balanced saline (P=0.029). Conclusions. Multiple prognostic factors were identified that may predict visual outcome and globe survival after IOFBs injury. Age, initial presenting visual acuity, wound length, complications (vitreous hemorrhage, retinal breaks, and endophthalmitis), surgical approach, and intraocular tamponade were significant predictors of visual outcome.
