Abstract
Sporotrichosis is a subcutaneous mycosis that affects humans and animals, with a typically subacute or chronic evolution, caused by Sporothrix spp., a dimorphic fungus. Although the cutaneous form is the most frequent presentation, the ocular involvement has been more frequently diagnosed in endemic areas, affecting mainly children and the elderly. Approximately 80% of affected patients have the lymphocutaneous form, while only 2.3% have conjunctival lesions, with 0.7% showing primary ocular involvement. We describe two cases of sporotrichosis with ocular involvement in children through inoculation by felines, with a good response to antifungal treatment.

Abstract
Objective: To analyze the clinical characteristics and treatment of ocular injury caused by chestnut burr. Methods: Retrospective case series study. Data of 48 patients (48 eyes) with ocular injuries caused by chestnut burrs hospitalized in Qingdao Eye Hospital were collected from January 2013 to March 2019. All patients were followed up for at least 3 months. The time of seeking medical advice, lesion region, and characteristics and treatment methods were analyzed. Results: There were 48 patients, including 33 males and 15 females, aged 19 to 74 years [mean, (56±10) years]. The time of injury was late September (25 cases) and early October (23 cases). The shortest time to visit our hospital was 3 hours after injury, and the longest was 8 months after injury. There were 13 cases (27.1%, 13/48) with corneal and/or scleral foreign bodies. All patients were treated with corneal or scleral foreign body extraction. Twenty-four patients (50.0%, 24/48) developed fungal keratitis. Among them, 18 patients had a corneal ulcer, and the infection involved the superficial or full-thickness corneal layer. Six patients had no corneal ulcer, and the infection involved the deep stroma and corneal endothelial surface. The positive rate of fungal examination by confocal microscopy was 87.5% (21/24). Antifungal drugs (2 cases), corneal debridement (5 cases), conjunctival flap covering (2 cases), corneal stroma injection (1 case), and penetrating keratoplasty(14 cases) were given according to the depth of fungal infection. Most of the pathogens were Alternaria spp. Eleven patients (22.9%, 11/48) with necrotizing scleritis were treated with exploration of the sclera. Three patients had scleral foreign body residues on ultrasound biomicroscopy examination, which were removed by operation. Four patients were found to have fungi at the necrotic site of the sclera. Conclusions: The main types of ocular injuries caused by chestnut burrs are corneal and/or scleral foreign bodies, fungal keratitis, and necrotizing scleritis. Chestnut burr foreign bodies should be removed as soon as possible. In the case of fungal keratitis, a drug or surgical intervention should be carried out as early as possible. Necrotizing scleritis is often induced by long-term foreign body retention. Scleral incision and exploration is an effective form of treatment. (Chin J Ophthalmol, 2020, 56: 370-375).

Abstract
Objective: To discuss clinical features and treatments of fungal keratitis, and to provide statistical data for clinical therapy and increase the therapeutic effects. Methods: This is a retrospective case series study. An analysis was performed by collecting patients' demography features, risk factors, onset time, lab results, clinical features and treatment from 1 414 cases of fungal keratitis from January 2006 to October 2016 in Qingdao Eye Hospital, Shandong Eye Institute. Results: In the 1 414 cases (1 414 patients), 1 174 patients (83.0%) came from different areas in Shandong Province, and the rest mainly from provinces on the north of Yangtze River. The age was 40 to 60 years in 874 cases (61.4%). The onset time was often in autumn and winter. The average duration between the onset and treatment was 1 to 74 days; 942 patients (67.1%) visited our hospital in 8-30 days after the appearance of the symptoms. Corneal trauma was the most common risk factor, especially injury by plants (367 cases, 26.4%). The positive rate of direct microscopic examination of potassium hydroxide wet mounts was 96.4%. The positive rate of confocal microscopy was 89.8%. Fungi were detected in corneal ulcer scrapings and (or) diseased corneal tissues obtained during surgery from 973 patients (68.8%). Most of the fungi were Fusarium (595 cases, 61.1%), followed by Alternaria (184 cases, 18.9%) and Aspergillus (119 cases, 12.2%). There were 603 cases (42.7%) of superficial and middle stromal infiltration, 614 cases (43.4%) of deep stromal infiltration and 197 cases (13.9%) of full-thickness corneal infiltration. Diameters of the corneal ulcer lesion were mostly between 4 and 6 mm (725 cases, 51.6%), followed by<3 mm (372 cases, 26.4%) and>6 mm (302 cases, 22.0%). Hypopyon was combined in 498 cases (35.2%), corneal perforation in 34 cases (2.4%), and endophthalmitis in 58 cases (4.1%). Surgery was performed in 1 198 cases (84.8%), including penetrating keratoplasty in 416 cases (29.4%), lamellar keratoplasty in 199 cases (14.1%), and corneal ulcer debridement in 532 cases (37.6%), with an effective rate of 98.1% (408 cases), 97.0% (193 cases) and 92.8% (494 cases), respectively. Two hundred and fifteen cases (15.2%) were treated with medical therapy alone, of which 147 cases (68.4%) were cured. Fifty-six patients (3.9%) finally lost their eye balls, including 54 cases of evisceration and 2 cases of ophthalmectomy. Conclusions: Fusarium is the main causative agent of fungal keratitis in Shandong Province. Direct microscopic examination of potassium hydroxide wet mounts is a simple, rapid and effective test method. Early diagnosis can be made if the result of corneal ulcer scraping examination is positive. Antifungal drug treatments can be done in early onset time. If the drug efficacy is poor or the patient's condition gets worse, immediate surgery is the key to controlling fungal keratitis. (Chin J Ophthalmol, 2020, 56:286-293).

Abstract
Mucormycosis is a rare, rapidly progressive life threatening opportunistic fungal infection, with rhinocerebral mucormycosis being the most common type. Rhinocerebral mucormycosis usually presents symptoms similar to sinusitis and orbital cellulitis during its early stage,which often leads to a misdiagnosis at the very beginning,and progresses rapidly to endophthalmitis,blindness,sclera perforation, eyeball atrophy, and even gets the central nervous system involved, thus leading to death. Mucormycosis is particularly common in patients with poor glycemic control, ketoacidosis and immunosuppression. The purpose of this review is to highlight the predisposing factors, infection pathway, pathogenesis, clinical presentations, diagnosis, and management of rhinocerebral mucormycosis, hence further promote the early diagnosis and immediate treatment of the disease.

Abstract
Objective: To analyze the sensitivity and specificity of fungal fluorescent staining in the diagnosis of fungal keratitis, and to compare it with conventional fungal culture, in vivo confocal microscopy (IVCM) and Giemsa staining. To explore its value of clinical application. Methods: Prospective case-control study. A total of 105 consecutive patients (105 eyes) diagnosed with infectious keratitis at Beijing Tongren Hospital from August 2017 to April 2018 were included. Patients with infectious keratitis were divided into fungal keratitis (FK) group and non-fungal keratitis (NFK) group by slit lamp microscopy, corneal in vivo confocal microscopy (IVCM) examination, and the results of Giemsa staining, fluorescent staining and pathogenic culture of corneal scraping from ulcer. The sensitivity and specificity of the above-mentioned examination methods for the diagnosis of fungal keratitis were analyzed. The receiver operating characteristic curve (ROC curve) and Area Under Curve (AUC) values were calculated to determine the diagnostic value of fungal fluorescent staining for fungal keratitis. Results: Among the 105 patients with infectious keratitis, 66 were fungal keratitis, 39 were non-fungal keratitis (29 cases of bacterial keratitis and 10 cases of acanthamoeba keratitis). Isolation from fungal keratitis were mainly Fusarium spp. (43.5%), followed by Alternaria spp. (21.7%) and Aspergillus spp. (19.6%). After fluorescent staining of the ulcer smear, the background of tissue demonstrated homogeneous black or weak blue fluorescence. The cell wall of fungi showed bright blue-violet to blue fluorescence, and the morphology, structure and hyphal density were easily recognized. The sensitivity of different methods for the diagnosis of corneal fungal infection were smear fluorescence staining (97.0%), IVCM (87.9%) , Giemsa staining (86.7%), and fungal culture (69.7%); the specificity of fungal culture was the highest (100%), followed by IVCM and Giemsa staining (94.9%), and fluorescent staining (87.2%). The ascending order of AUC values was: fungal culture (0.848) <Giemsa staining (0.906) <IVCM (0.914) <fluorescence staining (0.921). Conclusion: Fungal fluorescent staining is a rapid and sensitive screening method under microscope with high sensitivity and specificity for the diagnosis of fungal keratitis. It is especially suitable for the diagnosis of patients with low load of hypha or after antifungal therapy. (Chin J Ophthalmol, 2019, 55:601-608).

Abstract
Objective: To evaluate the efficacy of vitrectomy and etiological diagnosis in the treatment of fungal endophthalmitis. Methods: A retrospective survey was done on the clinical manifestation, etiological diagnosis and treatment efficacy of 15 patients (15 eyes) who had been diagnosed with fungal endophthalmitis at the inpatient department of Peking Union Medical College Hospital during 2002-2015. A total of 15 eyes of 15 patients, 3 male and 12 female patients, were included in this study. The mean age of the patients was (45.8±15.3) years. Among the 15 eyes, 12 (12 patients) were diagnosed with endogenous fungal endophthalmitis and 3 (3 patients) were diagnosed with exogenous fungal endophthalmitis. Fourteen eyes have been misdiagnosed with uveitis, systematic or local application of glucocorticoid and/or immunosuppressor have been conducted on the patients which resulted in exacerbation. Baseline visual acuity: light perception in 2 eyes, hand movement for 12 eyes, and 1 eye of 0.1. Six eyes showed slight inflammatory reaction in anterior chamber, four eyes showed moderate inflammatory reaction in anterior chamber, while five eyes showed severe inflammatory reaction with hypopyon in anterior chamber. B-Scan ultrasound examination showed inflammatory vitreous opacity in all 15 eyes, combined proliferative vitreoretinopathy (PVR) were found in 11 eyes, retinal detachment were found in 10 eyes, which include 6 cases of tractional retinal detachment, 1 case of exudative retinal detachment, and 3 cases of retinal and choroid detachment. Forty eyes underwent vitrectomy, 1 eye underwent intravitreal injection. Nine eyes were processed with silicone oil tamponade, one eye was processed with C(3)F(8) tamponade. At the beginning of the operation, vitreous fluids were collected for preparing smears which were later used for fungus culture and drug susceptibility testing. Results: According to the smear results of vitreous fluid, fungal hyphae and spores were found in 10 eyes. The fungus culture indicated positive results in 12 eyes, including candida albicans in 6 eyes, fusarium, candida parapsilosis, paecilomyces lilacinus, asoergullus terreus, mulan candida and aspergillus in 1 eye respectively. Based on etiological diagnosis, 14 eyes received amphotericin B intraocular injection during operation, and 9 patients received fluconazole (venous transfusion or oral administration), 2 patients received voriconazole through venous transfusion or oral administration, one patient received itraconazole through oral administration. All 15 eyes received local application of amphotericin B eyedrop or fluconazole eyedrop. The intraocular inflammations in all 15 eyes were mitigated. The visual acuity improved in 6 eyes, remained unchanged in 4 eyes, and reduced in 5 eyes. Postoperative visual acuity achieved 0.1 to 0.15 in 2 eyes, 0.01 to 0.04 in 2 eyes, CF in 2 eyes, HM in 4 eyes, LP in 2 eyes, and NLP in 3 eyes. The retina of 5 eyes remained in position, the retina of 2 eyes reattached, the retina of 2 eyes failed to reattach. Recurrent retinal detachment happened in the other 6 eyes, 5 of which received reoperation. Eventually, the retina of 10 eyes reattached, and the retina of the 5 eyes failed to reattach. Conclusions: Vitrectomy is an effective method for treatment of fungal endophthalmitis. The positive rates of vitreous smear and fungus culture were really high. Application of sensitive anti-fungal drugs based on etiological diagnose can improve therapeutic level. (Chin J Ophthalmol, 2018, 54: 270-276).

Abstract
Objective: To evaluate the clinical features of retrocorneal fungal infection and the therapeutic effects. Methods: This was a retrospective, noncomparative study of nine patients with retrocorneal fungal infection and an intact corneal epithelium treated at Qingdao Eye Hospital. The history, clinical features, diagnostic methods, pathogens and therapeutic effects were analyzed. Results: Five patients had a history of trauma by plant, two had a non-plant injury, and two had unidentified reasons. The duration between the initial onset and the first visit to our hospital was 7.9 months (range, 3 months to 2 years). There was endothelial plaque and sometimes with white infiltration in the deep stroma, but the corneal epithelium remained integrated, and the anterior stroma was uninfected. The patients were misdiagnosed as uveitis, herpes simplex keratitis or bacterial keratitis in the other hospitals. Visual acuity was 20/200 in four eyes, 20/60 in one eye, 20/40 in two eyes, and 20/30 in two eyes. Fungal hyphae were detected by confocal microscopy in six eyes. All the eyes had poor response to the antifungal medication before penetrating keratoplasty was performed. The smear examinations of the corneal endothelial plaque showed fungal hyphae in six eyes. Alternaria Nees, Apospory, Phialophora verrucosa, and Fusarium were identified. Conclusions: Plant injury is the most common risk factor of retrocorneal fungal infection. Slow onset and no initially obvious symptoms may lead to delayed diagnosis and misdiagnosis. The diagnosis can be confirmed by confocal microscopy before surgery. The effect of antifungal medication is usually poor. (Chin J Ophthalmol, 2017, 53:758-765).

Abstract
Objective: To investigate the treatment effect of keratectomy combined with intrastromal injection of voriconazole on fungal keratitis. Methods: Retrospective study. Ninety-eight fungal keratitis patients (98 eyes) were treated by keratectomy combined with intrastromal injection of voriconazole in Shandong Eye Hospital from January 2013 to May 2015. The corneal ulcers were mostly located in the paracentral or peripheral cornea, which incompletely blocked the pupil area. Slit lamp and anterior segment optical coherence tomography (AS-OCT) were used for lesion detection. The maximum lesion diameter was ≤5 mm, and the maximum depth was not more than half of the full corneal thickness. Because the anti-fungal drug treatment for 3-7 days was not effective, keratectomy was performed with intrastromal injection of voriconazole. The excision extension was 0.5 mm greater than the ulcer diameter, and keratectomy could be repeated until the infiltrative tissues were completely removed. Anti-fungal drug therapy was carried on after surgery. The wound healing and complications were observed. Results: All the subjects were diagnosed as fungal keratitis by corneal scraping and confocal microscopy. With an average lesion diameter of (3.72±1.23) mm, the corneal ulcers were located in the paracentral cornea in 30 patients (30.6%) and in the peripheral cornea in 68 patients (69.4%). The infiltrative depth of 74.5% of the cases detected by AS-OCT were ≤1/2 corneal thickness. The fungal keratitis in 95 cases was cured successfully. Conjunctival flap covering surgery (2 cases) and penetrating keratoplasty (1 case) were performed when the conditions were poorly controlled. Among the 95 cured cases, the ulcer healing time ranged from 3 to 19 days, and ≤7 days in more than half of the cases (48 cases). The average corneal thickness was (433.2±119.3) μm at 3 months, and the corneal endothelial cell density was (2 344.0±404.6) cells/mm(2). The uncorrected visual acuity was improved in 71(74.7%) eyes, of which 3 cases had a vision of 1.0. Conclusions: For fungal keratitis with a lesion diameter of<6 mm and a depth not more than half of the full corneal thickness, keratectomy combined with intrastromal injection of voriconazole could achieve ideal outcomes. The visual acuity recovered quickly, the therapy course was shortened, and the necessity of keratoplasty and other high risk surgeries was reduced. (Chin J Ophthalmol, 2017, 53: 682-688).

Abstract
Objective: To analyze the etiology, drug susceptibility and etiological changes of fungal keratitis so as to to provide reference for clinical diagnosis and treatment. Methods: Retrospective case series study. A total of 5 654 copies of specimens for fungal culture were collected from Outpatients suspected of fungal keratitis in Beijing Tongren Ophthalmic Center during January 2007 and December 2016. Specimens were inoculated on Potato dextrose agar (PDA) slant medium, incubated at 30℃ and 40% humidity constantly for 3 to 10 days. Filamentous fungi isolated from positive cultures were identified according to morphological traits. Yeast-like fungi were identified by API 20 C Aux. Drug susceptibility tests were performed by using ROSCO disk diffusion method, which included natamycin, terbinafine, itraconazole, fluconazole, amphotericin B, voriconazole. The Chi-square test and Spearman correlation analysis were performed using SPSS 20.0 software. Results: The positive rate of culture was 26.1%. In positive patients, the ratio of male to female was 1.77∶1, and the age range was 11 days to 95 years. The mean age was 49.0±16.9 years. Among isolated fungi, Fusarium sp. was the most common genus, accounting for 53.5% (789 strains) , followed by 17.5% of Aspergillus sp. (259 stains) and 13.8% of Alternaria sp. (203 stains). The sensitive rate of natamycin was 92.3% (410 strains) , followed by that of terbinafine as 78.5% (1 093 strains), voriconazole as 41.0% (338 strains), amphotericin B as 40.7% (553 strains). Conclusion: The predominant patients of fungal keratitis are adult and male. Fusarium sp., Aspergillus sp., and Alternaria sp. are three common species in northern china with seasonal changes in their proportion. Natamycin should be the preferred drug for empirical treatment. The preferred empirical treatment for Aspergillus sp. is terbinafine. Fluconazole should not be used alone due to the high resistant rate. (Chin J Ophthalmol, 2018, 54: 432-436).

Abstract
Objective: To identify the primary disease spectrum and trends of surgical procedure of keratoplasty patients. Methods: Retrospective case series study. To review all patients who underwent keratoplasty at Department of ophthalmology in Tongji Hospital from January 1, 2012 to December 31, 2015. The data collected included age, sex, birthplace, and primary corneal disease and associated surgical procedures. Then the data were compared with similar papers domestic and foreign. Results: A total of 315 keratoplasties were performed during this 4-year period. The average age of patients at time of surgery was (42.0± 1.8) years, range from 33 days to 89 years, 229 cases (72.7%) were from 18 to 65 years; male: female ratio was 2.06:1. Totally 289 cases (91.8%)came from Hubei province, 26 cases (8.2%) were from other provinces. The leading indications for corneal transplantation were keratitis in 125 cases (39.7%), followed by corneal scar in 71 cases (22.5%), keratoconus in 41 cases (13.0%), pseudophakic bullous keratopathy in 26 cases (8.3%), corneal dermoid in 18 cases (5.7%), corneal dystrophy and degeneration in 16 cases (5.1%), and others (including chemical injuries, thermal burns, post-traumatic corneal scar and corneal opacity) in 18 cases (5.7%). Of the 125 keratitis cases, 51 cases (40.8%) were associated with fungus, 43 cases (34.4%)were associated with virus, and 24 cases (19.2%)were associated with bacterial. In accordance with the classification of corneal transplant surgery, penetrating keratoplasty was performed in 212 cases (67.3% ), lamellar keratoplasty was completed in 87 cases (27.6% ), corneal endothelial transplantation was made in 16 patients (5.1%). Conclusions: Infectious keratitis was the leading indication for corneal transplantation followed by corneal scar, keratoconus and pseudophakic bullous keratopathy in Tongji hospital patients who underwent keratoplasty. And fungus was the first cause of infectious keratitis. Penetrating keratoplasty was still the main part of corneal transplantation. (Chin J Ophthalmol, 2017, 53: 460-463).

Abstract
Objective: To observe the early immunological rejection prevention effect of tacrolimus eye drops combined with glucocorticoids on fungal keratitis patients who received penetrating keratoplasty (PKP). Methods: In a retrospective case series study, medical records of fungal keratitis patients who received PKP in Shandong Eye Institute from March 2013 to December 2015 were reviewed. Twenty-six patients (26 eyes) were given tacrolimus eye drops, and 24 patients (24 eyes) were given 1% cyclosporine A eye drops immediately after PKP. Two weeks after PKP, these patients were given low concentration of glucocorticoids if no fungal recurrence was found. Immune rejection, fungal recurrence, intraocular pressure, and drug irritation symptoms were monitored. Data were analyzed by chi-square test and independent t-test. Results: The average follow-up was 7 months (range, 3 to 12 months) postoperatively. The rejection rate was 15.3% in the tacrolimus group and 47.8% in the cyclosporine A group (χ(2)=5.510, P<0.05). One patient in the tacrolimus group and two patients in the cyclosporine A group suffered fungal recurrence. Two patients in the tacrolimus group and four patients in the cyclosporine A group had secondary glaucoma. The intraocular pressure was controlled. Three patients receiving tacrolimus eye drops and 13 patients receiving cyclosporine A eye drops had mild irritation symptoms. Conclusions: Tacrolimus eye drops combined with low concentration of glucocorticoids can prevent the early immunological rejection after PKP for fungalkeratitis effectively and safely.
