“…Nesse caso o fluido seria liquor produzido no espaço subaracnoide. Recentemente, Kuhn et al (10) relataram migração intracraniana de óleo de silicone em um caso de fosseta de disco óptico que foi previamente tratado com vitrectomia. Menos provavelmente, a origem do fluido seria vazamento de vasos sanguíneos na base da fosseta, mesmo porque a angiofluoresceinografia não mostra vazamento na área da fosseta (11) .…”

Artigo Original | Original article INTRODUÇÃOA fosseta de disco óptico congênita é uma depressão oval, geralmente, localizada no segmento ínfero-temporal do disco óptico e que, frequentemente, está associada à presença de descolamento seroso da mácula (1,2) . Sua incidência é em torno de uma para cada 11 mil pessoas (1) , acometendo ambos os olhos em apenas 15% dos casos (3) .Geralmente, a fosseta de disco óptico é assintomática, podendo causar diminuição da visão por complicações maculares tais como descolamento seroso, retinosquise ou alterações pigmentares (3) .Petersen (4) foi o primeiro a descrever a relação entre a presença da fosseta de disco óptico e o descolamento seroso da retina que, geralmente, está confinado à macula. Tais descolamentos ocorrem entre 25 e 75% dos casos (5,6) e a grande maioria deles ocorrem nos casos de fossetas localizadas na região temporal do disco óptico, tornando-se sintomáticos por volta da terceira década de vida (3) . Embora a resolução espontânea do descolamento seroso da mácula possa ocorrer, em geral, o prognóstico quanto à visão central é ruim, especialmente nos casos de descolamentos serosos de longa duração (5) .Diversos tratamentos foram propostos para a maculopatia por fosseta de disco óptico. O presente estudo mostra resultados e acompanhamento de longo prazo de 5 olhos com o problema e que foram submetidos a cirurgia intraocular. MÉTODOSCinco olhos de 5 pacientes, 3 homens e duas mulheres, com idade variando entre 16 e 39 anos e que apresentavam descolamento seroso de mácula por fosseta de disco óptico foram submetidos a vi trectomia via pars plana, remoção da membrana hialoide posterior, Vitrectomia e troca fluido-gasosa para o tratamento do descolamento seroso da mácula por fosseta de disco óptico: avaliação de longo prazo Vitrectomy and gas-fluid exchange for the treatment of serous macular detachment due to optic disc pit: long-term evaluation

“…On NECT scans, silicone oil appears hyperdense, with an attenuation higher than hemorrhage, usually measuring 70-140 Hounsfield units (HU). In addition, silicone oil characteristically forms convex fluid-fluid interfaces in the non-dependent ventricles (due to the high surface tension and low specific gravity of silicon oil) [6,7,11,12]. On MRI, silicone oil is hyperintense on T1-weighted imaging with a prominent chemical shift artifact [13].…”

“…Another hypothesis by Knecht et al suggests that active physiologic processes facilitate silicone oil migration [1]. A final hypothesis is that silicone oil migration occurs in patients with anatomic variants such as an optic pit or coloboma [11]. While distinct mechanisms for intraventricular silicone oil migration exist, there may be overlap among them.…”

“…1 In ODP, previous reports only inferred that there were direct communications among the SAS, vitreous cavity, and subretinal space. [3][4][5] Kuhn et al 5 reported a case of ODP in whom intravitreally injected silicone oil was detected intracranially indicating a communication between the SAS and the vitreous cavity. Our findings demonstrated a direct communication between the SAS and the vitreous cavity in an eye with an ODP.…”

A 66-year-old man diagnosed with ODP was examined with an SS-OCT instrument (DRI OCT-1, Topcon, Tokyo, Japan). The patient had visual disturbances in his left eye, and his best-corrected visual acuity was 1.2 OD and 0.7 OS. The intraocular pressure was 14 mm Hg OU. Slit-lamp examination of both eyes and fundus examination of the right eye were unremarkable. Fundus examination of the left eye showed an ODP with macular retinoschisis (Figure 1). SS-OCT clearly delineated the SAS and its direct communication with the vitreous cavity (Figure 2). The opening in the optic disc became clearly visible by a three-dimensional OCT reconstruction. Perimetry showed no glaucomatous visual field defects. Brain and orbital magnetic resonance imagings were normal. CommentIn our case, the macular retinoschisis was most likely the cause of the visual impairment. The schisis formation is the initial step in the evolution of serous retinal detachments associated with ODPs. 2,3 Krivoy et al 2 suggested that the ODP acts as a conduit for fluid flow between the SAS and the schisis cavity or subretinal space. In our case, SS-OCT delineated a thin line of fluid in the disc that was presumably connected to the SAS.Ohno-Matsui et al 1 reported that SAS could be seen by SS-OCT in 93.2% of highly myopic eyes. They described that an SAS was seen as a hyporeflective space around the optic nerve. In one myopic patient, there was a direct communication between the SAS and the vitreous cavity. 1 In ODP, previous reports only inferred that there were direct communications among the SAS, vitreous cavity, and subretinal space. [3][4][5] Kuhn et al 5 reported a case of ODP in whom intravitreally injected silicone oil was detected intracranially indicating a communication between the SAS and the vitreous cavity. Our findings demonstrated a direct communication between the SAS and the vitreous cavity in an eye with an ODP. Conflict of interestThe authors declare no conflict of interest. We read with interest the article on 'Spontaneous haemorrhage in an eyelid hidrocystoma in a patient treated with clopidogrel' by Novitskaya et al. 1 We agree with the authors that eyelid apocrine hidrocystomas typically present as skin-colored, translucent lesions. However, our experience has shown that hemorrhagic hidrocystomas may be more common than previously reported, with or without a history of clopidogrel use. Here, we describe two cases of hemorrhagic apocrine hidrocystomas. Both of the hidrocystomas underwent excision and pathologic examination.A 78-year-old male with a history of coronary artery disease on systemic clopidogrel and aspirin presented for evaluation for a non-painful, pigmented eyelid lesion. The patient was uncertain of the exact time of onset of the lesion, but felt that it was stable for the past 2 months. He denied any preceding trauma to the periocular tissue. Examination revealed a translucent dome-shaped cystic lesion along the left upper eyelid (Figure 1a). Detailed examination revealed a horizontal, linear demarcation suggestive of lay...
