We reported an 8-year-old boy with panscleritis in left eye and right epididymitis after falling on the ground. Etiologic diagnosis played a key role in this case. Systemic examinations ruled out systemic autoimmune diseases, tumors, and infections as the cause of scleritis and suggested that the disease was caused by a local delayed-type hypersensitivity (DTH) induced by ocular trauma and was non-infectious. Still, the right epididymitis was infectious. Both conditions were treated successfully using steroids and antibiotics, respectively. Thus, early etiologic diagnosis and reasonable treatment are crucial to prevent visual loss.

OBJECTIVETo determine the prevalence of ocular trauma and the proportion of blindness and visual impairment due to trauma in a rural population in northern China.

METHODSThe Handan Eye Study is a population-based cross-sectional study that surveyed 6830 Chinese people aged 30+ years from 13 randomly selected villages in Yongnian County, city of Handan, Hebei Province, in July, 2006. All participants underwent a standardized interview and extensive examinations. A structured questionnaire was used to collect information on ocular trauma.

RESULTSOf the 5837 participants who filled out the questionnaire, 124 subjects [2.1%; 95% confidence interval (CI), 1.8%-2.5%] reported a history of ocular trauma in either eye, including 19 (0.3%) persons reporting trauma in both eyes. Men were more likely to have an eye injury than women [odds ratio (OR), 3.3; 2.2-4.9]. In multiple logistic regression models, ocular trauma was significantly more frequent among normotensive participants when compared with hypertensive participants (hypertensive vs. normotensive: OR, 0.6; 0.4-0.9) and among participants who had a history of falls (OR, 2.4; 1.2-4.8). The proportion of unilateral visual impairment and unilateral blindness due to trauma were 10.5% (13 subjects) and 21.0% (26 subjects), respectively.

CONCLUSIONOur study reports the prevalence of severe ocular trauma among adults in rural China, revealing a high proportion of blindness and visual impairment due to trauma. These findings suggest the need for educational strategies to increase eye health awareness in this rural population with focus on providing at least appropriate first aid care to reduce blindness due to trauma.

Traumatic rupture of the superior oblique muscle is rare. We report a case of a 54-year-old man injured by the metal hook of a hanger, resulting in a rupture of the superior oblique muscle tendon. He complained of torsional diplopia when in the primary position. The distal margin of the superior oblique muscle was reattached to sclera 5 and 9 mm apart from the medial insertion of the superior rectus muscle. One week after the operation, torsional diplopia disappeared. However, a 4-prism diopter ipsilateral hypertropia was observed. Three months later, hypertropia gradually increased to 20 prism dioptors and the second operation was done to correct vertical diplopia.

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.

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.

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.

OBJECTIVE: To examine the effect of genistin on traumatic proliferative vitreoretinopathy (PVR) in rabbits. METHODS: Traumatic PVR was induced in pigmented rabbits by intravitreal injection of platelet rich plasma. The eyes then received an intravitreal injection of dimethyl sulfoxide (0.1 mL), 2 or 40 μg genistin (0.1 mL), and 1 mg fluorouracil(0.1 mL), respectively to form 4 groups. The eyes were examined ophthalmoscopically on distinct days after the surgery and the stage of PVR was evaluated. The model eyes and normal eyes in the 40 μg genistin group carried ERG test on the 28th day. All model eyes in the 4 groups were observed by light microscope on the 28th day. RESULTS: In the control eyes, the retina was detached after 10 d, the PVR had progressed to higher stages with time. In the eyes injected 40 μg genistin or fluorouracil, the PVR also developed; however, the severity of PVR was lower than that in the control eyes. PVR was significantly inhibited in the 40 μg genistin group compared with the control eyes after 14 d (P<0.05). Histological examination of the genistin-treated eyes disclosed no morphological changes, and ERG analysis revealed no significant functional changes. CONCLUSION Intravitreal injection of genistin is safe and effective in reducing traumatic PVR in clinical treatment.
