- Bilateral acute visual loss from Rathke's cleft cyst apoplexy in a patient with dengue fever(2014) SUZUKI, Ana Claudia De Franco; ARAUJO, Rafael Barbosa de; SOUZA, Eduardo Cunha de; MONTEIRO, Mario Luiz RibeiroHemorrhagic complications of optic pathway diseases are extremely rare causes of acute visual loss associated with dengue fever. In this paper we report a patient presenting with dengue fever and bilateral acute visual loss caused by chiasmal compression due to Rathke's cleft cyst apoplexy. Considering the importance of early diagnosis and treatment to visual recovery, apoplexy of sellar and suprasellar tumors should be considered in the differential diagnosis of patients with acute visual loss and dengue fever.
- Unilateral papilledema and peripapillary polypoidal choroidal vasculopathy as the presenting manifestations of intracranial hypertension(2021) MATOS, Aline Mota Freitas; CUNHA, Leonardo Provetti; SUZUKI, Ana Claudia F.; MELLO, Luiz Guilherme Marchesi; PRETI, Rony C.; ZACHARIAS, Leandro C.; MONTEIRO, Mario L. R.We have reported here the case of a 54-year-old woman with intracranial hypertension that presented with the unique features of unilateral papilledema and peripapillary polypoidal choroidal vasculopathy. Our investigations lead to the diagnosis of idiopathic intracranial hypertension and an incidental small right frontal meningioma. The patient was accordingly treated with oral acetazolamide, followed by three consecutive monthly intravitreal injections of bevacizumab, which resulted in the inactivation of the polypoidal choroidal vasculopathy, marked reduction of lipid exudation, and complete absorption of the subretinal fluid. This case serves as the first documentation of polypoidal choroidal vasculopathy associated with papilledema. It also demonstrates that choroidal vascular abnormalities may occur even when optic disk edema is unilateral, which is an uncommon manifestation of increased intracranial pressure. Prompt recognition of such findings and its appropriate management are essential for adequate treatment and prevention of irreversible visual loss.
- Fechamento espontâneo de buraco de mácula em olhos previamente vitrectomizados: relato de dois casos(2014) SUZUKI, Ana Claudia de Franco; ZACHARIAS, Leandro Cabral; NÓBREGA, Mário Junqueira; PRETTI, Rony Carlos; TAKAHASHI, Walter YukihikoThe spontaneous closure of a full-thickness macular hole (MH) developed after vitrectomy is very uncommon. We report a small series of cases (two patients) with this presentation. The first patient developed a MH 1 month after vitrectomy for an epirrretinal membrane and, the second one, 3 weeks after vitrectomy for rhegmatogenous retinal detachment. The MHs resolved spontaneously 2 months and 1 month after their documentation by optical coherence tomography(OCT), respectively. In this case report, we review the literature on spontaneous closure of MHs and discuss possible mechanisms for this rare event.
- Choroidal Thickness in Eyes with Band Atrophy of the Optic Nerve from Chiasmal Compression(2022) MELLO, Luiz Guilherme Marchesi; SUZUKI, Ana Claudia F.; MELLO, Giuliana Rovito de; PRETI, Rony Carlos; ZACHARIAS, Leandro C.; MONTEIRO, Mario L. R.Background. The choroid is a vascular tissue that helps maintain retinal and prelaminar optic nerve head function. Choroidal thickness has been previously studied in diseases accompanied by retinal neural loss, but the relationship between the two sets of measurements is not clear. In eyes with temporal hemianopia as a result of chiasmal compression lesions (CCL), retinal neural loss tends to be greater in the nasal than the temporal hemiretina, a fact that may be useful in evaluating the effect of inner retinal layer loss on choroidal thickness. Purpose. To evaluate macular and peripapillary choroidal thickness on swept-source optical coherence tomography (SS-OCT) in eyes with temporal hemianopia as a result of chiasmal compression and in healthy controls. Methods. 33 eyes of 26 patients with band atrophy of the optic nerve and temporal visual field defects as a result of previously treated suprasellar tumors (CCL group) and 40 eyes of 21 healthy controls underwent SS-OCT scanning. The thickness of the peripapillary retinal nerve fiber layer (pRNFL), the peripapillary choroid (pChoroid), the macular RNFL (mRNFL), the macular ganglion cell layer (mGCL), and the macular choroid (mChoroid) was expressed globally and by sector (peripapillary quadrants and macular hemifield and quadrants). Ratios between macular nasal and temporal hemifield and quadrantic measurements were calculated using generalized estimated equation models, and the two groups were compared. Results. The pRNFL, mRNFL, and mGCC thicknesses were significantly smaller in the CCL group than in the control group (64.67 +/- 10.53 mu m, 29.68 & nbsp;+/- 5.80 mu m, and 80.60 & nbsp;+/- 10.17 mu m vs. 103.78 & nbsp;+/- 12.23 mu m, 39.89 & nbsp;+/- 3.82 mu m, and 105.51 +/-& nbsp;7.76 mu m, respectively; p < 0.001). For the choroid, the only difference between the groups was increased macular nasal hemifield and superonasal quadrant thickness in CCL (222.47 & nbsp;+/- 61.05 mu m and 230.45 +/- 58.59 mu m in the CCL group, respectively vs. 190.68 & nbsp;+/- 52.54 mu m and 197.65 & nbsp;+/- 54.80 mu m in the control group, respectively; p < 0.05). The temporal/nasal ratios were significantly higher for the mRNFL and mGCC parameters and significantly lower for the mChoroid parameters in the CCL group, except for the superotemporal/superonasal quadrant ratio. Conclusions. The choroid does not thin after the inner retinal layer becomes damaged due to CCL and may even be thicker in some areas with corresponding severe retinal neural loss. While further studies are needed to interpret these findings, choroidal thinning is most likely not secondary to optic nerve disease-related inner retinal neural loss.
- Case report: pneumatic retinopexy for the treatment of progressive retinal detachment in senile retinoschisis(2015) SUZUKI, Ana Claudia de F.; ZACHARIAS, Leandro Cabral; TANAKA, Tatiana; ROCHA, Diego Neves; TAKAHASHI, Walter Y.Retinoschisis is an abnormal separation of the retinal layers and is asymptomatic in most cases. Enlargement of the area of retinoschisis and retinal tear and detachment are possible complications of the disease, and the treatment of retinoschisis is controversial. In this case report, we present a case of retinal detachment associated with senile retinoschisis in which pneumatic retinopexy was chosen as the treatment of choice and was performed successfully in one of the eyes. After a literature review on retinoschisis and pneumatic retinopexy for the treatment of associated retinal detachment, we found only one case that was successfully treated without drainage of subretinal fluid, using air as the filler. However, no previous reports have been found in the literature on the effectiveness of pneumatic retinopexy using C3F8 as the sole treatment for progressive retinal detachment in senile retinoschisis.
