Endophthalmitis is the inflammation of the intraocular cavities, and panophthalmitis is its most severe form.1 2 3 In panophthalmitis, there is a marked inflammation of the surrounding orbital structures, manifested by severe eyelid edema, proptosis, chemosis and eye movement limitations.4 If left untreated, endophthalmitis could lead to irreversible vision loss and systemic complications.

PURPOSE: To report two cases of postoperative endophthalmitis caused by Streptococcus dysgalactiae subspecies equisimilis (SDSE), which appeared as hyperacute presentation and panophthalmitis. CASE SUMMARY: A 68-year-old male was treated with cataract surgery and was evaluated the next day (less than 24 hours after surgery) because of acute loss of vision. There was severe inflammation and the visual acuity was light perception. The patient underwent pars plana vitrectomy (PPV) with intravitreal antibiotic injection. The vitreous culture revealed SDSE. After PPV, regression of inflammation was observed, although the corneal edema had progressed. The cornea evolved to decompensate due to bullous keratopathy and visual acuity of the eye decreased to no light perception after 3 months. A 87-year-old male who underwent phacoemulsification and intraocular lens implantation 2 days previously was hospitalized due to severe ocular pain and visual loss. There was severe inflammation, and the visual acuity was no light perception. The patient received only intravitreal injections of antibiotics due to severe corneal necrosis. The aqueous humor revealed SDSE. Four days after intravitreal injection, erythema and swelling of the eyelid of the affected eye was observed, and diagnosed as panophthalmitis. After treatment with intravenous antibiotics, cellulitis of the eyelid was resolved. The eye progressed as phthisis after 3 months without recurrence. CONCLUSIONS: Postoperative SDSE endophthalmitis showed aggressive and hyperacute presentation, resulting in blindness despite prompt treatment. SDSE is an emerging organism and should be considered a potential cause of postoperative endophthalmitis.

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.

This study analyzed the recent causes, prognosis, and treatment strategies for fungal endophthalmitis. A retrospective review of patients who were diagnosed with fungal endophthalmitis at our center was conducted. The fungal organisms isolated from each patient and the visual prognosis according to the route of infection and treatment method were analyzed. A total of 40 eyes from 30 patients with fungal endophthalmitis were included in this study. Candida species were the most common causative organisms in 35 of 40 eyes. Endogenous and exogenous endophthalmitis were observed in 33 and 7 eyes, respectively. Pre- and post-treatment best-corrected visual acuity (BCVA) was not significantly different between endogenous endophthalmitis and exogenous endophthalmitis. The 40 eyes were treated using the following modalities: intravitreal antifungal agent injection with intravenous antifungal agent (16 eyes), vitrectomy with intravenous antifungal agent (14 eyes), intravenous antifungal agent alone (9 eyes), and evisceration (1 eye). Post-treatment BCVA only significantly improved after treatment in the vitrectomy group. Candida species were the most common cause of fungal endophthalmitis, irrespective of the route of infection. The visual prognosis of fungal endophthalmitis was generally poor. In conclusion, if the general condition of the patient tolerates a surgical procedure, prompt vitrectomy and intravitreal injection of antifungal agents can improve visual acuity.

PURPOSE: To evaluate the factors affecting treatment outcome of graft infection following penetrating keratoplasty (PKP). METHODS: In this retrospective study, 28 patients who underwent PKP between January 2005 and January 2013 and who were diagnosed with graft infection were classified into a treatment success group or a treatment failure group. Demographic and clinical characteristics, as well as the results of the microbiologic investigation, were analyzed and compared. A subsequent binary logistic regression analysis was performed to identify the prognostic factors affecting treatment outcome. RESULTS: Graft infection occurred at a mean of 38.29 +/- 36.16 months (range, 1 to 96 months) after PKP. Seventeen patients developed bacterial keratitis, and 11 patients developed fungal keratitis. Overall, of the 28 patients, nine (32.1%) were classified in the treatment failure group. Multivariate analysis identified pre-existing graft failure (p = 0.019), interval longer than 72 hours between donor death and PKP (p = 0.010), and fungal infection (p = 0.026) as significant risk factors for treatment failure. CONCLUSIONS: Pre-existing graft failure, extended interval between donor death and PKP, and fungal infection were important risk factors for treatment failure of graft infection following PKP.

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.

BACKGROUNDHypopyon is common in eyes with fungal keratitis. The evaluation of the clinical features, culture results and the risk factors for hypopyon and of the possible correlation between hypopyon and the treatment outcome could be helpful for making treatment decisions.

METHODSThe medical records of 1066 inpatients (1069 eyes) with fungal keratitis seen at the Shandong Eye Institute from January 2000 to December 2009 were reviewed retrospectively for demographic features, risk factors, clinical characteristics, laboratory findings and treatment outcomes. The incidence of hypopyon, the fungal culture positivity for hypopyon, risk factors for hypopyon and the effect of hypopyon on the treatment and prognosis were determined.

RESULTSWe identified 1069 eyes with fungal keratitis. Of the 850 fungal culture-positive eyes, the Fusarium species was the most frequent (73.6%), followed by Alternaria (10.0%) and Aspergillus (9.0%). Upon admission, 562 (52.6%) eyes with hypopyon were identified. The hypopyon of 66 eyes was evaluated via fungal culturing, and 31 eyes (47.0%) were positive. A total of 194 eyes had ocular hypertension, and 172 (88.7%) of these eyes had hypopyon (P < 0.001). Risk factors for incident hypopyon included long duration of symptoms (P < 0.001), large lesion size (P < 0.001) and infection caused by the Fusarium and Aspergillus species (P < 0.001). The positivity of fungal culture for hypopyon was associated with duration of symptoms and lesion size. Surgical intervention was more common in cases with hypopyon (P < 0.001). Hypopyon was a risk factor for the recurrence of fungal keratitis after corneal transplantation (P = 0.002).

CONCLUSIONSHypopyon is common in patients with severe fungal keratitis and can cause ocular hypertension. About half of the hypopyon cases were positive based on fungal culture. Long duration of symptoms, large lesion size and infection with the Fusarium and Aspergillus species were risk factors for hypopyon. The presence of hypopyon increases the likelihood of surgical intervention.

INTRODUCTIONThis study was conducted to determine the epidemiological pattern and risk factors associated with corneal ulcers in rural areas of western Maharashtra, India, and to identify the bacterial and fungal agents responsible for causing keratitis.

METHODSA total of 852 patients with corneal ulceration were included in the study. Sociodemographic data and information pertaining to risk factors were collected. Corneal scrapings obtained from these patients were processed for bacterial and fungal agents using standard techniques.

RESULTSOut of the 852 patients studied, 537 (63.02%) were culture positive. A majority of the culture-positive patients were farmers (52.32%), and ocular trauma was the most common predisposing factor (60.15%). Among these patients, fungal isolates (57.91%) were more frequent than bacterial isolates (42.08%). The most common fungal isolate was Fusarium spp. (35.04%) followed by Aspergillus spp. (18.00%). Streptococcus pneumoniae was the predominant bacterial isolates (32.74%) followed by Staphylococcus spp. (17.25%).

CONCLUSIONCorneal trauma from plant parts or organic matter was found to be the most common risk factor associated with corneal ulceration in the rural areas of western Maharashtra. Epidemiology and aetiology of microbial keratitis vary from region to region, and therefore, careful history taking and proper identification of aetiological agents are necessary for the institution of appropriate therapy.
