Pacientes com glaucoma e blefaroespasmo essencial: relato de casos

Essential blepharospasm is a facial dystonia characterized by spontaneous, spasmodic and involuntary contractions of the eyelid muscles. In advanced cases, blepharospasm patients develop severe eyelid spasms that render them functionally blind, socially reclusive, and unable to work or care for themselves. Oculoplastic surgeons frequently have to deal with patients with blepharospasm. The decrease in quality of life caused by this pathology drives all the attention to the resolution of the spasms. However, other conditions may be associated with them and must be kept in mind during the ophthalmological examination. Four patients with essential blepharospasm were diagnosed as glaucomatous during their follow-up at the Oculoplastic Service. All of them showed glaucomatous optic neuropathy and corresponding visual field defect and no clinically apparent secondary cause for their glaucoma. Forced eyelid closure may lead to intraocular pressure peaks. These patients with blepharospasm present repetitive and spasmodic eyelid contractions and the intraocular pressure rise observed during eyelid squeezing could be an additional risk factor for glaucomatous damage. Our case series suggest that patients with blepharospasm should be seriously evaluated for glaucoma.Blefaroespasmo essencial é uma distonia facial caracterizada por contrações espontâneas, espasmódicas e involuntárias dos músculos palpebrais, podendo tornar os pacientes funcionalmente cegos. Tais pacientes são geralmente referidos aos médicos oculoplásticos para avaliação e tratamento. Devido à intensidade dos espasmos e ao comprometimento da qualidade de vida, toda a atenção é dirigida à sua resolução e outras condições oculares associadas podem passar despercebidas. Neste estudo, quatro pacientes com blefaroespasmo foram diagnosticados como glaucomatosos durante o seu seguimento no Departamento de Plástica Ocular. As quatro pacientes apresentavam neuropatia óptica glaucomatosa e defeito no campo visual compatível, sem que houvesse nenhuma causa secundária para o glaucoma. O fechamento palpebral forçado causa importante aumento da pressão intra-ocular e estes pacientes com blefaroespasmo, por apresentar contrações espasmódicas e repetitivas das pálpebras, poderiam estar sob risco aumentado de desenvolver glaucoma

Spontaneous Absorption of Extensive Subinternal Limiting Membrane Hemorrhage in Shaken Baby Syndrome

The Shaken Baby Syndrome (SBS) is characterized by subdural hematomas (SH), retinal hemorrhages (RH), and multiple fractures of long bones without external evidence of head trauma. Subinternal limiting membrane (ILM) hemorrhage, also known as macular schisis, is a characteristic finding of this entity. There is no guideline on the right time to indicate surgical treatment. This report describes an abused child with massive sub-ILM hemorrhage, which showed spontaneous absorption after less than two months of follow-up. Due to the possible spontaneous resolution, we suggest an initial conservative treatment in cases of sub-ILM hemorrhage related to SBS

The effect of laser pan-retinal photocoagulation with or without intravitreal bevacizumab injections on the OCT-measured macular choroidal thickness of eyes with proliferative diabetic retinopathy

OBJECTIVES: To investigate the effect of laser pan-retinal photocoagulation with or without intravitreal bevacizumab injections on macular choroidal thickness parameters in eyes with high-risk proliferative diabetic retinopathy. METHODS: High-risk proliferative diabetic retinopathy patients undergoing laser treatment were prospectively enrolled in this study. One eye was randomly selected for laser treatment combined with bevacizumab injections, study group, whereas the corresponding eye was subjected to laser treatment alone, control group. Spectral-domain optical coherence tomography with enhanced depth imaging was used to measure the macular choroidal thickness prior to and 1 month after treatment. Measurements in both groups were compared. Clinicaltrials.gov: NCT01389505. RESULTS: Nineteen patients (38 eyes) with a mean±standard deviation age of 53.4±9.3 years were evaluated, and choroidal thickness measurements for 15 patients were used for comparison. The greatest measurement before treatment was the subfoveal choroidal thickness (341.68±67.66 μm and 345.79±83.66 μm for the study and control groups, respectively). No significant difference between groups was found in terms of macular choroidal thickness measurements at baseline or after treatment. However, within-group comparisons revealed a significant increase in choroidal thickness parameters in 10 measurements in the study group and in only 5 temporal measurements in the control group when 1-month follow-up measurements were compared to baseline values. CONCLUSIONS: The macular choroidal thickness does not appear to be significantly influenced by laser treatment alone but increases significantly when associated with bevacizumab injections in patients with proliferative diabetic retinopathy and macular edema. Because bevacizumab injections reduce short-term laser pan-retinal photocoagulation-induced macular edema, our findings suggest that the choroid participates in its pathogenesis

Socioeconomic Barriers to Rhegmatogenous Detachment Surgery in Brazil

Purpose. To verify access barriers patients with retinal detachment face to arrive at a reference center and to evaluate patients’ knowledge about the disease. Methods. Transversal study that applied a questioner to 65 patients of the Clinical Hospital of the University of Sao Paulo with retinal detachment between February and August of 2010. Results. Reasons for not performing the surgery in other services were as follows: 47% were referred because there was not vitreoretinal surgeon at original service; 27% could not afford the surgery, had no health insurance, or had no coverage at health insurance plan for the procedure. Time between the first symptom and the arrival at our service was as follows: 18 patients arrived in up to 7 days; 35 between 8 and 30 days; 8 between 31 and 90 days; 5 in more than 90 days. Reasons for delay were as follows: 70% did not know how serious the pathology was; 56% thought that it had spontaneous cure; 16% did not have money to pay for ophthalmic evaluation, 10% did not know where to go and 24% for other reasons. Conclusion. Educational programs about disease and measures to optimize the referral to specialized services are needed to accelerate the treatment of patients with rhegmatogenous retinal detachment

Effect of panretinal photocoagulation on the peripapillary retinal nerve fiber layer in diabetic retinopathy patients

OBJECTIVES: To determine the effect of panretinal photocoagulation (PRP) on the peripapillary retinal nerve fiber layer (RNFL) in nonglaucomatous patients with proliferative diabetic retinopathy (PDR). METHODS: This is a prospective, single center, observational study. Thirty-eight eyes of 26 diabetic patients underwent PRP for proliferative diabetic retinopathy. Peripapillary RNFL thickness was measured using scanning laser polarimetry (SLP) with variable corneal compensation (GDx VCC; by Carl Zeiss Meditec, Dublin, CA) and spectral-domain optical coherence tomography (OCT) (Heidelberg Spectralis, Carlsbad, USA) at baseline and 12 months after PRP was performed. RESULTS: Thirty-eight eyes of 26 patients (15 female) with a mean age of 53.7 years (range 26 to 74 years) were recruited. No significant difference was found among all RNFL thickness parameters tested by GDx VCC software (p=0.952, 0.464 and 0.541 for temporal-superior-nasal-inferior-temporal (TSNIT) average, superior average, inferior average, respectively). The nerve fiber indicator (NFI) had a nonsignificant increase (p=0.354). The OCT results showed that the average RNFL thickness (360o measurement) decreased nonsignificantly from 97.2 mm to 96.0 mm at 1 year post-PRP (p=0.469). There was no significant difference when separately analyzing all the peripapillary sectors (nasal superior, temporal superior, temporal, temporal inferior, nasal inferior and nasal thickness). CONCLUSION: Our results suggest that PRP, as performed in our study, does not cause significant changes in peripapillary RNFL in diabetic PDR patients after one year of follow-up

Idiopathic polypoidal choroidal vasculopathy masquerading as choroidal tumors: one year follow-up of a peripheral lesion

ABSTRACT This case report describes peripheral idiopathic polypoidal choroidal vasculopathy (IPCV) with a collection of small aneurysmal dilations that masqueraded as choroidal tumors in an elderly patient. A 68-year-old African American woman was referred to us with a suspected diagnosis of asymptomatic vascular choroidal tumor and choroidal capillary hemangioma, affecting the temporal peripheral fundus. Upon examination, optical coherence tomography (OCT) revealed two large hemorrhagic pigment epithelium detachments (PED), and indocyanine green angiography (ICG) confirmed the diagnosis of IPCV. One year later, there was reduction in the hemorrhagic pigment epithelium detachments and the lesion took on a different appearance, resembling a choroidal osteoma. No treatment was necessary despite the presence of multiple polyps. IPCV is a rare condition that can resemble other choroidal diseases depending on the stage of presentation. OCT is the best tool to determine the characteristics of the lesions, and indocyanine green angiography should be used to confirm the diagnosis. Not all cases require treatment
