[Familial exudative vitreoretinopathy: our experience]. / Vitreorretinopatía exudativa familiar: nuestra experiencia.

PURPOSE: To describe our experience in the diagnosis of Familial Exudative Vitreoretinopathy (FEVR) at its different clinical stages. We also report our outcomes in early treatment of this inherited disorder. METHODS: Retrospective interventional and descriptive case series of 11 patients (17 eyes) affected by FEVR evaluated and treated in our hospital. RESULTS: In our series, 33.3% of patients were classified as stage I, while 16.7% and 50% were classified as stage II and III, respectively. Visual acuity (VA) remained stable after treatment in stages I and II (mean VA was 0.8 and 0.4, respectively) but decreased in stage III. CONCLUSIONS: Early treatment of FERV may improve the visual prognosis and avoid complications such as subfoveal chronic exudation and vitreoretinal peripheral interphase contraction and fibrosis.

[Photodynamic therapy in adult-onset foveomacular vitelliform dystrophy]. / Terapia fotodinámica en distrofia foveomacular viteliforme del adulto.

CASE REPORT: We present the case of a patient who underwent photodynamic therapy (PDT) for adult-onset foveomacular vitelliform dystrophy (AFVD) at another clinic, having been misdiagnosed as having a choroidal neovascular membrane. Two years post-treatment, the patient had severe central visual loss and showed angiographic signs of choroidal hypoperfusion. DISCUSSION: AFVD is a rare clinical entity, usually having a fair visual prognosis, although some cases may show episodes of severe visual loss during their clinical course. Optical coherence tomography (OCT) is valuable in revealing the distinct images of AFVD from the features of a choroidal neovascular membrane. PDT using verteporfin may have negative long term effects if used in patients with AFVD.
