BACKGROUNDPediatric infectious endophthalmitis is a serious sight-threatening disease for children. The purpose of this study was to investigate the etiology, microbiological spectrum, and visual outcomes of infectious endophthalmitis in children at a single institution in China.
METHODSIt is a retrospective study of the medical records of all patients under 14 years of age with histories of infectious endophthalmitis, treated at a single institution from January 1, 2009 to January 1, 2015. The clinical characteristics, etiology, microbiological spectrum, and management, as well as the visual outcomes, were analyzed. The Kappa test and Chi-square test were used in the statistical evaluation.
RESULTSA total of 271 children were identified, with a mean age of 5.61 ± 2.93 years (range 5 months to 14 years). Ocular trauma (94.8%) and previous ocular surgery (3.0%) were the most common etiologies. Overall, 147 (54.2%) cases had positive cultures, and 176 organisms were isolated from these patients. A single species was isolated in 120 (81.6%) cases, with multiple organisms in 27 (18.4%) cases, and the most commonly identified organisms were coagulase-negative Staphylococcus and Streptococcus species, comprising 29.5% and 26.8% of the isolates, respectively. Moreover, of 176 isolates, 142 (80.8%) were Gram-positive organisms, 23 (13.0%) were Gram-negative organisms, and 11 (6.2%) were fungi. The final visual outcomes were 20/200 or better in 66 (24.4%) eyes, counting fingers to 20/200 in 34 (12.5%), hand motions in 30 (11.1%), light perception in 33 (12.2%), no light perception in 32 (11.8%), and 9 (3.3%) eyes were enucleated or eviscerated. The visual outcomes were not available in 67 (24.7%) patients.
CONCLUSIONSPenetrating ocular trauma is the most frequent cause of pediatric endophthalmitis in China. Streptococcus and Staphylococcus species are the most commonly identified organisms in exogenous pediatric endophthalmitis whereas Fusarium species are commonly seen in endogenous endophthalmitis. In this research, in spite of aggressive management with antibiotics and vitrectomy, the visual prognosis was found to be generally poor.

We describe herein a case of an impending corneal perforation with a large descemetocele in a patient with previous penetrating keratoplasty (PKP) that subsequently was treated with an emergent lamellar keratoplasty using frozen preserved cornea. A 76-year-old male patient, who had a PKP, presented with a completely whitish and edematous graft accompanied by large epithelial defects. Although antibiotics and antiviral agents were tried for three days, the corneal stroma abruptly melted, except for the Descemet's membrane and endothelium. Cryopreserved corneal tissue that was kept at -80degrees C was thawed and sutured on top of the remaining Descemet's membrane and endothelium. Pathological and microbiological tests were conducted using the remaining donor and recipient corneal tissues. After tectonic corneal transplantation on top of a large descemetocele, a healthy graft and relatively clear interfaces between graft-host junctions were maintained without serious adverse reactions throughout 6 month follow-up period. Microbiological evaluations of donor tissue at the time of thawing and tissue preparation were done, and the results were all negative. Tissue that was taken intraoperatively from the recipient cornea also showed negative microbiological results. In conclusion, tectonic lamellar keratoplasty, using cryopreserved corneal tissue, only onto the remaining Descemet's membrane and endothelium in an emergent condition, was a safe and effective treatment.

This case report describes a case of self-inflicted chronic bacterial keratoconjunctivitis involving the patient's own semen. A 20-year-old male soldier was referred to our clinic for the evaluation of refractory chronic bacterial conjunctivitis. Over the previous 4 months, he had been treated for copious mucous discharge, conjunctival injection, and superficial punctate keratitis in both eyes at an army hospital and a local eye clinic. Despite the use of topical and systemic antibiotics according to the results of conjunctival swab culture, there was no improvement. During the repeated smear and culture of conjunctival swabs, surprisingly, a few sperm were detected on Gram staining, revealing that the condition was self-inflicted bacterial keratoconjunctivitis involving the patient's own semen. Thus, in cases of chronic keratoconjunctivitis that do not respond to appropriate antibiotic treatment, self-inflicted disease or malingering should be considered.

Phialemonium keratitis is a very rare case and we encountered a case of keratitis caused by Phialemonium obovatum (P. obovatum) after penetrating injury to the cornea. This is the first case report in the existing literature. A 54-year-old male was referred to us after a penetration injury, and prompt primary closure was performed. Two weeks after surgery, an epithelial defect and stromal melting were observed near the laceration site. P. obovatum was identified, and then identified again on repeated cultures. Subsequently, Natacin was administered every two hours. Amniotic membrane transplantation was performed due to a persistent epithelial defect and impending corneal perforation. Three weeks after amniotic membrane transplantation, the epithelial defect had completely healed, but the cornea had turned opaque. Six months after amniotic membrane transplantation, visual acuity was light perception only, and corneal thinning and diffuse corneal opacification remained opaque. Six months after amniotic membrane transplantation, visual acuity was light perception only, and corneal thinning and diffuse corneal opacification remained.

5.LASIK Interface-Captured Foreign Bodies after Mild Traumatic Corneal Scratch without Flap Displacement.
Korean Journal of Ophthalmology 2012;26(3):222-225
A 38-year-old woman developed diffusely distributed opacities with crystalline materials in the laser in situ keratomileusis (LASIK) interface of her eye after she was scratched by a sprig during mountain climbing. No sign of flap displacement was noted. Despite two days of topical and systemic antibiotics therapy, the corneal infiltration with interface opacities persisted. The following day, the distribution of the crystalline materials had rotated in a counterclockwise direction. Flap lifting and foreign body removal using sufficient irrigation were performed. One month after surgery, the patient's postoperative uncorrected visual acuity was 0.8 with cleared interface. No signs of epithelial ingrowth or flap striae were noted. Mild traumatic corneal scratching without flap displacement may threaten the integrity of the LASIK interface. If foreign bodies are suspected to be the cause of inflammation, early flap lifting with irrigation is imperative for successful treatment.

6.Tectonic Deep Anterior Lamellar Keratoplasty in Impending Corneal Perforation Using Cryopreserved Cornea.
Korean Journal of Ophthalmology 2011;25(2):132-135
We report a case of tectonic corneal transplantation for impending corneal perforation to preserve anatomic integrity using cryopreserved donor tissue. An 82-year-old woman exhibiting impending corneal perforation suffered from moderate ocular pain in the left eye for one week. After abnormal tissues around the impending perforation area were carefully peeled away using a Crescent blade and Vannas scissors, the patient received tectonic deep anterior lamellar keratoplasty using a cryopreserved cornea stored in Optisol GS(R) solution at -70degrees C for four weeks. At six months after surgery, the cornea remained transparent and restored the normal corneal thickness. There were no complications such as corneal haze or scars, graft rejection, recurrent corneal ulcer, and postoperative rise of intraocular pressure. Cryopreserved donor lamellar tissue is an effective substitute in emergency tectonic lamellar keratoplasty, such as impending corneal perforation and severe necrotic corneal keratitis.

We report a case of a retained graphite anterior chamber foreign body that was masquerading as stromal keratitis. A 28-year-old male visited with complaints of visual disturbance and hyperemia in his right eye for four weeks. On initial examination, he presented with a stromal edema involving the inferior half of the cornea, epithelial microcysts, and moderate chamber inflammation. Suspecting herpetic stromal keratitis, he was treated with anti-viral and anti-inflammatory agents. One month after the initial visit, anterior chamber inflammation was improved and his visual acuity recovered to 20/20, but subtle corneal edema still remained. On tapering the medication, after three months, a foreign body was incidentally identified in the inferior chamber angle and was surgically removed resulting in complete resolution of corneal edema. The removed foreign body was a fragment of graphite and he subsequently disclosed a trauma with mechanical pencil 12 years earlier. This case showed that the presence of an anterior chamber foreign body should always be considered in the differential diagnosis of idiopathic localized corneal edema.

PURPOSE: To evaluate whether systemically injected bone marrow-derived mesenchymal stem cells (MSCs) can be incorporated into neuroretinal tissues and play an important role in retinal wound healing in the laser-induced retinal trauma model. METHODS: Retinotomies were made by applying an Nd:YAG laser to rat retina. On the first day after the injuries, cell suspensions that were obtained from the same line of rat (containing 1 x 10(6) green fluorescence protein [GFP]-marked bone marrow-derived MSCs) were injected through a tail vein in the experimental group and phosphate buffer solution (PBS) was injected in the same way in the control group. Fundus photographs were taken serially for fundus examination and eyeballs were enucleated for histological studies that were conducted at five and seven weeks after MSC and PBS injection. After the tissues were prepared, the retinotomy sites were observed with routine histological staining and confocal microscopy. RESULTS: Retinal detachment resolved in the experimental group, whereas it progressed in the control group. The retinotomy sites closed partially with identifiable GFP positive cells 5 weeks after MSC injection. At 7 weeks after MSC injection, complete healing without retinal detachment and plentiful GFP positive cells were observed at the transitional zone between damaged and normal retina. CONCLUSIONS: Systemically administered GFP-marked MSCs may be incorporated into the neuroretinal tissues and play an important role in the wound modulation of physically damaged retinal tissues.

PURPOSE: To report on the anatomical and functional changes to the macula in nine patients suffering from commotio retinae not accompanied by any other types of traumatic retinopathy. METHODS: Nine injured eyes with commotio retinae were evaluated soon after ocular trauma with ophthalmic examination, including Spectral-domain optical coherence tomography (SD-OCT). In 12 eyes of 6 patients, Humphrey visual field (HVF) and multifocal electroretinogram (mfERG) were performed. Re-examinations were periodically performed for a mean of 26 days. Data from 9 injured eyes were collected and compared to data collected from the 9 non-affected eyes of the same patients. RESULTS: SD-OCT revealed no significant differences in the foveal thickness and total macular volume between traumatized and intact eyes in all 9 patients. Only 3 out of the 9 injured eyes showed abnormal findings in SD-OCT images such as discontinuity of the inner/outer segment (IS/OS) junction or abnormal hyper-reflectivity from the IS/OS and retinal pigment epithelium (RPE) lines in the macula. HVF and mfERG results did not show any functional deterioration in the injured eyes compared with intact eyes. During follow-up, the commotio retinae resolved in all 9 eyes. The changes to the outer retinal region detected in 3 patients by SD-OCT were also resolved. CONCLUSIONS: Acute retinal changes in commotio retinae, not associated with other retinal pathologies, were resolved without histological and functional sequelae. In a few cases of commotio retinae, SD-OCT revealed transient abnormalities mainly observed at the IS/OS and RPE complexes.

Journal of Forensic Medicine 2009;25(3):195-197
OBJECTIVE:
To study the injury modes, the injury characteristics, the disability grade assessments and other relative problems in eye injuries after traffic accidents.
METHODS:
Eighty four ocular disability cases after traffic accidents collected from March 2007 to March 2009 in our institute were retrospectively analyzed. Then to study the ocular disability reasons, the assessment time and methods.
RESULTS:
The main cause of ocular disability is visual dysfunction, and the other causes for example eyeball missing, injury of eyelid, injury of lacrimal apparatus, traumatic cataract and defect of visual field were rare relatively. Most ocular injuries happened to single eye. The disability grades were often from VII to X.
CONCLUSION
The accuracy of visual function expertise could be improved by using some tests and visual electrophysiological measurements. The vision and ophthalmology data before the injury of the wounded who has intrinsical disease should be provided. The assessment time should be delayed for people whose visual function still may change.
