目的:应用OCT动态观察急性中心性浆液性脉络膜视网膜病变(acute central serous chorioretinopathy,ACSC)细微结构的变化,比较其激光治疗、药物治疗与二者联合治疗的疗效。方法:经FFA及OCT确诊的96例98眼ACSC患者,应用OCT比较单纯药物治疗、激光治疗以及激光联合药物治疗对视网膜下液的吸收,并比较各组间的视力差异。随访时间为治疗后2,4,8wk。结果:各组之间在治疗前视网膜脱离范围均没有统计学意义。在治疗后2,4,8wk比较,激光治疗组与药物治疗组间视网膜脱离范围和治愈率均没有统计学意义;联合治疗组与前两组比较,其视网膜脱离范围更小,治愈率更高,其差异均有统计学意义。结论:药物联合激光治疗急性中心性浆液性脉络膜视网膜病变能缩短病程,提高治愈率;OCT无创、简便、直观,能对CSC的愈后过程进行灵敏的追踪。 相似文献
Background Hypopyon 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.
Methods The 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.
Results We 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).
Conclusions Hypopyon 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.
