Objective To summarize the visual outcome of patients with severe ocular trauma treated with vitreous surgery. Methods Clinical data of 188(191 eyes) with severe ocular trauma treated with vitreous surgery in a period from November 1996 to April 1998 were analysed retrospectively. Results The study included penetrating injury in 56 eyes, foreign bodies in the posterior segment in 70 eyes, blunt injury in 41 eyes , and globe rupture in 24 eyes. Main complications included endophthalmitis in 35 eyes, choroidal bleeding in 20 eyes, retinal detachment in 60 eyes, and vitreous hemorrhage in 97 eyes. Post-opera-tively, out of 188 eyes, except for 3 of patients too young to examine, visual acuity improved in 133(70.7%), including 85(45.2%) with visal acuity 0.02-1.0, 46(24.5%) remained unchanged; and 9(4.8%) had worse vision. Among 34 with no-light-perception, 12 had light-perception or over. Conclusion A majority of severe trauma eyes can be salvaged with considerable visual recovery after adequate and timely vitreous surgery. (Chin J Ocul Fundus Dis,1999,15:4-6)
Ocular trauma is the most common cause of monocular vision loss in children. Among the patients with eye trauma in China, 15%-20% are children. The complexity of diagnosis and treatment and the uncertainty of prognosis are high because the ocular tissue of children is not fully developed and the history collection and examination are difficult. In order to further standardize the treatment of children's eye trauma and improve the treatment level, China Ocular Trauma Society has formulated Expert consensus of the treatment of pediatric ocular trauma in China by combining domestic and foreign literature and the actual medical situation in China. This consensus provides detailed recommendations on the classification, cause of injury, history collection, examination methods, diagnosis and treatment principles of pediatric eye trauma. This consensus applies to Chinese ophthalmologists and medical personnel engaged in the treatment of children's eye trauma, aiming to provide scientific guidance for the diagnosis and treatment of children's eye trauma, assist clinical decision-making, and further improve the treatment level of children's eye trauma in China.
Objective To evaluate the rapid diagnosis of bacterial and (or) fungal endophthalmitis by multiplex polymerase chain reaction (MPCR). Methods MPCR was performed to detect the DNA segment of bacteria and (or) fungi from standard strains and 41 samples of intraocular fluid or vitreous from 38 patients (3 with double eyes and 35 with single), and the results were compared with the cultured bacteria and fungi. Results Five hours after detected by MPCR, bacteria and (or) fungi in 34 out of 41 samples (82.9%) from patients were detected，in cluding bacteria in 26，fungi in 6，and both bacteria and fungi in 2. The positive rate of MPCR was obviously higher than the cultured ones（χ2＝9.60, P＜0.05）. Conclusion With the advantages of rapidity, sensibility, and specificity, MPCR can make for the rapid and definitive diagnosis of bacterial and (or) fungal endophthalmitis.

ObjectiveTo observe and analyze the clinical features and prognosis of endogenous klebsiella pneumoniae endophthalmitis (EKPE).MethodsThis is a retrospective case series study. Seven patients (8 eyes) with EKPE were enrolled in this study. There were 3 males (4 eyes) and 4 females (4 eyes). The ages were from 39 to 76 years, the mean age was 57.29 years. All these cases had no history of trauma and surgery. Meanwhile, they all had some risk factors, such as infection, diabetes mellitus, systemic lupus erythematosus, liver abscess, renal insufficiency undergoing dialysis treatment, Hodgkin lymphoma and so on. All the eyes were undertaken visual acuity, slit lamp and fundus examination to observe the eye conditions. Seven eyes were undertaken pars plana vitrectomy with intravitreal injection of antibiotics from 2 days to 2 weeks after onset. And only one eye was undertaken intravitreal injection of antibiotics without surgery. Microbial stains and culture were performed for 7 eyes using vitreous and aqueous fluid samples from the procedures of vitrectomy. Meanwhile, culture and drug sensitive tests were performed from blood samples. According to the result of the drug sensitive tests, carbapenems such as imipenem and meropenem were used in each patient through intravenous injection from 1 to 2 weeks. During the follow up period from 3 days to 1 year, prognosis was observed at each office visit.ResultsFrom these eight eyes, presenting visual acuity was light perception (4 eyes), hand motion (3 eyes), 0.1 (1 eye). Hypopyon (6 eyes), aqueous fluid opacity (2 eyes) and diffuse vitreous opacity (8 eyes) were found. Changes in fundus like optic disc, macular edema and retinal vascular occlusion could be observed. Cultures of the vitreous and aqueous fluid samples from vitrectomy were all point out to klebsiella pneumoniae. At last office visit, the visual acuity of patients with hypopyon was no light perception (1 eye), light perception (1 eye), hand motion (1 eye). The visual acuity of patients without hypopyon was 0.05 (1 eye) and 0.5(1 eye). Finally, 1 eye was underwent enucleation and one patient with binocular disease was died of multiple organ failure.ConclusionsEKPE is almost unilateral attacked. Changes in fundus like optic disc, macular edema and retinal vascular occlusion can be observed. EKPE is commonly associated with poor visual outcomes. It is useful to save patients’ visual acuity by performing vitrectomy before hypopyon happened.
Objective To analyze the causes and pathogens of infectious endophthalmitis in our hospital. Methods The clinical data and laboratory findings of 282 inpatients with infectious endophthalmitis were retrospectively reviewed. There were 206 males（73.05%）and 76 females（26.95%）with a mean age of (36.0plusmn;11.2) years (range from 2 to 79 years). Except 14 patients who lost their eyeballs as of serious conditions, pathogen examinations of vitreous specimen had been performed for all remaining 268 cases. The clinical and laboratory data were statistically analyzed by Chi-square and Kappa consistency tests, when P＜0.05 the difference should be considered as statistically significant. Results The 4 major causes of infectious endophthalmitis of those 282 patients included ocular trauma (177 cases, 62.77%), infectious keratitis (61 cases, 21.63%), eye surgery (32 cases, 11.35%), and endogenous endophthalmitis (12 cases, 4.25%). 19.21% of the patients in ocular trauma group was 2-13 years old, 55.74% of the patients in infectious keratitis group was 14 -50 years old, and 60.61% of the patients in eye surgery group was 51-79 years old. The major pathogens were fungus and staphylococci each accounted for 30.63% of all cases. Most of the pathogenic bacteria were sensitive to ciprofloxacin (81.81%) and gentamicin (77.92%). Conclusions The major reason of infectious endophthalmitis was ocular trauma, and the major pathogens were fungus and staphylococci. Those findings may help us to treat infectious endophthalmitis patients appropriately.
