- 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.
conferenceObject Evaluation of OCTA peripapillary vascular density in eyes with temporal hemianopia from chiasmal compression. Correlation with retinal nerve fiber layer and visual field loss(2018) SUZUKI, Ana Franco; CUNHA, Leonardo Provetti; ZACHARIAS, Leandro C.; PRETI, Rony Carlos; MONTEIRO, Mario L. R.- Circumpapillary and macular vessel density assessment by optical coherence tomography angiography in eyes with temporal hemianopia from chiasmal compression. Correlation with retinal neural and visual field loss(2020) SUZUKI, Ana Claudia F.; ZACHARIAS, Leandro C.; PRETI, Rony C.; CUNHA, Leonardo P.; MONTEIRO, Mario L. R.Aims To compare the circumpapillary and macular vessel density (cpVD/mVD) of eyes with temporal visual field (VF) defect and band atrophy (BA) of the optic nerve and normal controls using OCTA and to verify the association of VD parameters with circumpapillary retinal nerve fibre layer (cpRNFL) thickness, macular ganglion cell complex (mGCC) thickness and VF loss. Methods Thirty-three eyes of 26 patients with BA and 42 eyes of 22 age-matched normal controls underwent OCT + OCTA scanning. cpVD and cpRNFL were expressed as average and sector measurements. mVD and mGCC were calculated as averages and in quadrants and hemiretinas. VF loss was estimated using the 24-2 and the 10-2 protocols. Generalized estimated equation models were used for comparisons and area under the receiver operating characteristics (AROC) were calculated. Results Compared with controls, BA eyes displayed smaller average cpVD and mVD values (p < 0.001 and AROC = 0.91 for both). Sectorial measurements were also reduced, especially the nasotemporal sector average cpVD (p < 0.001 and AROC = 0.96) and the nasal retina mVD measurements (p < 0.001 and AROC = 0.93). cpVD and mVD correlated strongly with corresponding cpRNFL and mGCC thickness measurements in affected regions (r range: 0.67-0.78 and 0.56-0.76, respectively). Similarly, cpVD and mVD parameters correlated significantly with corresponding VF loss (r range: 0.45-0.68). Conclusions cpVD and mVD are significantly reduced in BA eyes compared with controls and are strongly correlated with retinal neural and VF loss. cpVD and mVD reduction on OCTA could serve as a surrogate for retinal neural loss in compressive optic neuropathy and might be useful in its management.

conferenceObject SERIOUS OPHTHALMOLOGIC COMPLICATIONS OF PRIMARY IMMUNODEFICIENCY PATIENTS(2012) ALVAREZ, H. T.; SUZUKI, A. C. F.; TAKIUTI, J. H.; FERRIANI, M. P.; DORNA, M.; SANTOS, C.; PASTORINO, A. C.; CASTRO, A. P. B.; CARNEIRO-SAMPAIO, M.; JACOB, C. M.Introduction: Primary immunodeficiencies (PID) are genetic diseases characterized by high susceptibility to infections. Although the manifestations affect all organs, there are few reports about ocular complications. Objective: To describe four patients with serious ophthalmologic complications in Brazilian patients followed at a reference center for PID. Methods: It was a retrospective study including patients with ocular serious complains. Medical records of 4 PID patients were evaluated for clinical data and the PID diagnosis was based on the PAGID/ ESID criteria. These patients underwent to ophthalmologic evaluation, including visual acuity, biomicroscopy and fundus examination. Ophthalmologic evaluation was done routinely only for AT and CHS diagnosis. Results: The PIDs patients included were: HLH, GCD, CMC and A-T. The HLH patient had a heterozygous mutation at the perforin gene (FHL type 2), CMC patient had a heterozygous mutation at STAT1. Ocular complains were: ocular pain, hyperemia, eyelids edema and strabismus and the characteristics of each patient were: - Female, 13y, CMC- conjunctivitis and eyelids edema with infraorbital infected papules. - Female, 6 mo, HLH- acute strabismus in consequence of neurological involvement by HLH. - Male, 15y, AT- herpes conjunctivitis and loss of vision in left eye. - Male, 9y CGD - Conjunctivitis in the left eye, progressing to edema and proptosis. The diagnosis was endophthalmitis granulomatous with loss of vision in left eye. Conclusion: Although not common in PID patients, the ocular complications may lead to loss of vision. The ophthalmologic evaluation would be routinely recommended for all PID patients to avoid important sequels.- 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.
- Homonymous Hemianopic Hyporeflective Retinal Abnormality on Infrared Confocal Scanning Laser Photography: A Novel Sign of Optic Tract Lesion(2016) MONTEIRO, Mario L. R.; ARAUJO, Rafael B.; SUZUKI, Ana C. F.; CUNHA, Leonardo P.; PRETI, Rony C.Infrared confocal scanning laser photography of a patient with long-standing optic tract lesion revealed a homonymous hemianopic hyporeflective image contralateral to the visual field defect. Spectral domain optical coherence tomography showed thinning of the retinal nerve fiber and retinal ganglion cell layer and thickening of the inner nuclear layer (with microcystic degeneration) in the macular area, matching the infrared image. Hyporeflective image on infrared laser photography is associated with retinal degeneration secondary to anterior visual pathway disease and, when located in homonymous hemianopic retinas, may represent a new sign of an optic tract lesion.
- 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.
