However, applying a SB duri ng PPV may produce a risk of choroidal haemorrhage. Following a recent pilot stu dy showing that such cases can be safely treated by PPV without SB the authors r e examined their management of RRD in which inferior breaks were present. Metho ds: All patients had a detached vitreous and a complex configuration of retinal breaks. A case control study was performed to analyse the surgical methods and results of PPV on 48 consecutive patients with RRD associated with inferior brea ks and 48 age/sex matched controls who underwent PPV for RRD without inferior br eaks. Exclusion criteria were giant retinal tears, retinal dialysis, trauma, pro liferative vitreoretinopathy (PVR) grade B or higher, schisis detachments, and e yes that had been operated previously for RRD. A simple algorithm was followed t o manage patients with inferior breaks. All patients underwent a standard three port PPV with intraocular gas tamponade without supplementary SB. Patients were asked to posture face up or right or left side down for 1 week. Results: 39 of t he 48 patients (81.3%) with inferior breaks were treated successfully with one operation. 41 of 48 patients (85.4%) control patients achieved primary success. The final success rate was 95.8%in both groups. There was no statistical diffe rence between the two groups. When all the cases of RRD were analysed (including external plomb/non drain procedures) the primary success rate was 89%and fina l success rate 97.5%Conclusions: This study has shown that acceptable success r ates can be achieved using PPV alone to treat RRD with inferior breaks. Complica tions are minimised and patients in this high risk group have an 81%chance of p rimary success. Pars plana vitrectomy and gas will successfully reattach the ret ina and a supplementary SB, to support the inferior retina, is unnecessary as th e intraocular gas, and face up or, right or left side down positioning will tamp onade breaks satisfactorily.展开更多

The patient was a carrier of the 13q14 retinoblastoma gene. His retinal lesion remained stable during the follow-up period without signs of malignant transformation. Retinomas are most commonly observed in patients with retinoblastoma and their relatives. In this case, none of the patient’s parents, siblings, or children had evidence of a retinal tumor. Photographic documentation of the nonprogressive nature of this presumed retinoma is provided and demonstrates the absence of growth.展开更多

Fundus fluorescein angiography depicted staining of the drusen without any sign of pooling of the dye, whereas optical coherence tomography displayed detachment of the retinal pigment epithelium. These findings remained unchanged during a 10-month period.展开更多
