Scleral buckling versus vitrectomy for young japanese patients with rhegmatogenous retinal detachment in the era of microincision surgery: real-world evidence from a multicentre study in Japan.

PURPOSE: To evaluate real-world evidence for young Japanese patients with rhegmatogenous retinal detachment (RRD) by retrospectively examining surgical procedures and clinical outcomes in the Japan Clinical Retina Study group. METHODS: This was a multicentre retrospective study of the medical records of 562 young patients (384 males and 178 females; mean age: 33.0 ± 11.8 years) who had been diagnosed with RRD and who underwent surgical procedures in participating centres during the period between April 2013 and August 2016. RESULTS: The selected surgeries were scleral buckling (SB) for 295 eyes (49.7%) and pars plana vitrectomy (PPV) for 262 eyes (44.1%). Between the two surgical procedures, there was no significant difference in the primary anatomical reattachment rate (PARR, SB = 92.2%, PPV = 93.9%); improvements in vision were noted in both groups. The incidences of proliferative vitreoretinopathy and cataract formation within 1 year of PPV were 2.3% (p = 0.0047) and 6.5% (p = 0.0005), whereas they were 0% and 1.0% in the SB group, respectively. CONCLUSION: Scleral buckling (SB) and PPV were chosen with almost equal frequency for young patients with RRD. Clinical outcomes for SB and PPV exhibited a similar PARR. The incidence of cataract formation after PPV may constitute an important limitation of the procedure.

Severe fungal sclerokeratitis caused by Metarhizium anisopliae: a case report and literature review.

To date, there has been only one published report on the infectious sclerokeratitis caused by Metarhizium anisopliae, which is an entomopathogenic fungus. Regarding corneal infection, three reports have been published to date. Although the prognoses of the corneal infections are favourable, prognosis when scleral infection is involved is very poor. A 76-year-old patient presented with foreign body sensation in the left eye. Microscopic examination with Fungi Flora Y staining of the corneal scraping revealed fungal infection. The conjunctiva was melted by the infection over a wide area. Although intensive medications were administered, an emergency surgery was necessary because scleral thinning, corneal perforation and lens prolapse occurred. The fungal isolate was identified as M. anisopliae by sequencing the internal transcribed spacer region. Herein, we report the second known case worldwide of M. anisopliae sclerokeratitis, and we review the literature related to the ocular infections.

Polymicrobial sclerokeratitis caused by Scedosporium apiospermum and Aspergillus cibarius.

PURPOSE: The aim of this study was to report the first case of polymicrobial fungal sclerokeratitis caused by infection with both Scedosporium apiospermum and Aspergillus cibarius, and notify the medical community of the possibility of infection caused by A. cibarius in humans. METHODS: A 78-year-old woman presented to a medical practitioner with epiphora and a purulent discharge in her left eye. After concurrent administration of topical antibiotics and systemic steroids, her symptoms worsened, and she was referred to the Tokushima University Hospital. Because of suspected fungal infection, microscopic examination and cultivation of both corneal and scleral scrapings were performed. RESULTS: Fungi were observed on microscopic examination, and S. apiospermum was isolated only from the sclera in the early stage of the clinical course. Although administration of an adequate medication regimen comprising topical and systemic antifungal drugs resulted in an improvement in the sclera, keratitis persisted, and the infected sclera was melted. After scleral transplantation, administration of systemic caspofungin and high concentrations of voriconazole solution eye drops resulted in a gradual improvement in keratitis. A strain of filamentous fungus was isolated from the cornea 6 weeks after the cultivation on a Sabouraud agar plate, and it was identified as A. cibarius. CONCLUSIONS: A. cibarius may infect human tissue. Coinfection of the cornea and the sclera with 2 different species of fungi is likely to follow a complex clinical course.
