Chronic chorioretinal detachment under normal intraocular pressure in eye with uveitic glaucoma after trabeculectomy: A case report.

RATIONALE: Choroidal detachment is a major postoperative complication of trabeculectomy. Postoperative choroidal detachment occurs with low intraocular pressure (IOP), and is naturally resolved by elevation of IOP. We report a case of chronic chorioretinal detachment (CRD) in the eye with uveitic glaucoma after trabeculectomy which persisted with normal IOP resistant for medication and required surgery. PATIENT CONCERNS: A 63-year-old man was referred to our department with uncontrolled uveitic glaucoma in his right eye. At first presentation, IOP was 62 mm Hg in the right eye with opened angle, and active ocular inflammation was presented by moderate cell infiltration to the anterior chamber. DIAGNOSIS: Uveitic glaucoma. INTERVENTIONS: Trabeculectomy with mitomycin-C combined with phacoemulsification were performed without any surgical trouble. Postoperative inflammation in the anterior segment was mild, and IOP decreased to the middle-teen. OUTCOMES: At 19 days after surgery, the depth of the anterior chamber changed to shallow and CRD occurred in the inferior quadrant area. This complication could not be resolved by additional systemic corticosteroid medication and scleral fenestration. Although IOP was maintained in middle-teen range, suture fixation of the sclera flap and additional scleral fenestration were necessary to resolve CRD at 191 days after primary surgery. LESSONS: In uveitic eye with uncontrolled ocular hypertension, severe CRD after trabeculectomy is able to occur even with normal IOP, which requires surgical procedure in addition to the medical treatment.

Loop-mediated isothermal amplification with the Procedure for Ultra Rapid Extraction kit for the diagnosis of pneumocystis pneumonia.

Loop-mediated isothermal amplification (LAMP) is an innovative molecular technique requiring only a heating device and isothermal conditions to amplify a specific target gene. The results of current microscopic diagnostic tools for pneumocystis pneumonia are not sufficiently consistent for detecting infection with a low-density of Pneumocystis jirovecii. Although polymerase chain reaction (PCR) is highly sensitive, it is not suitable for resource-limited facilities. LAMP is a potential diagnostic replacement for PCR in such settings but a critical disadvantage of DNA extraction was still remained. Therefore, we employed the Procedure for Ultra Rapid Extraction (PURE) kit, which uses a porous material, to isolate the DNA from clinical samples in a simple way in combination with previously reported LAMP procedure for diagnosing PCP. The detection limit of the PURE-LAMP method applied to artificial bronchoalveolar lavage fluid samples was 100 copies/tube, even with the use of massive blood-contaminated solutions. In addition, we concluded the diagnostic procedure within 1 h without the need for additional equipment. PURE-LAMP coupled with suitable primers for specific pathogens has good potential for diagnosing various infectious diseases.
