1. Correlação entre as espessuras da mácula e da camada de fibras nervosas da retina, medidas pelas tomografias de coerência óptica de dominio Fourier e de domínio do tempo, e a perimetria automatizada na atrofia em banda do nervo óptico / Correlation between macular and retinal nerve fiber layer Fourier domain and time domain optical coherence tomography measurements and visual field loss in band atrophy of the optic nerve
PURPOSE: To investigate the relationship between fourier-domain optical coherence tomography (FD - OCT) measured macular and retinal nerve fiber layer thickness (RNFL) and visual field sensitivity loss on standard automated perimetry in eyes with permanent temporal hemianopia from chiasmal compression and compare the ability of FD - OCT and time-domain optic

2. Fatores de risco e métodos diagnósticos para retinopatia por difosfato de cloroquina nos portadores de lúpus eritematoso sistêmico / Risk factors and screening methods for chloroquine retinopathy in systemic lupus erythematosus patients
Purpose: To evaluate risk factors and screnning methods for retinopathy in systemic lupus erythematosus patients after chronic use of chloroquine. Methods: Seventy-two eyes of 36 consecutive patients, followed in the Division of Rheumatology of Hospital das Clínicas, School of Medicine, São Paulo University, were analised from July 2007 to April 2008.

3. Comparação das medidas da espessura macular e da camada de fibras nervosas retiniana para detecção de atrofia em banda do nervo óptico através da tomografia de coerência óptica / Comparison of macular thickness and retinal nerve fiber thickness measurements for detection of band atrophy of the optic nerve using optical coherence tomography
Pacientes com compressão quiasmática apresentam perda das fibras nervosas da retina nasal que decussam no quiasma óptico. Por conseguinte, ocorre perda das fibras nervosas, predominantemente, no setor nasal e temporal do disco óptico, que se manifesta por atrofia em banda do nervo óptico ao exame oftalmoscópico e hemianopsia temporal ao exame de campo

4. The influence of intraocular pessure reduction with medication on retinal nerve fiber layer thickness measurements obtained with scanning laser polarimetry in glaucomatous and hypertensive eyes / Influencia da redução medicamentosa da pressão intra-ocular na medida da espessura da camada de fibras nervosas da retina de olhos hipertensos e glaucomatosos pela polarimetria de varredura a laser
Objetivo: Avaliar o efeito da redução da pressão intra-ocular (PIO) obtido com o uso de terapia medicamentosa na espessura da camada de fibras nervosas da retina medida pela Polarimetria de Varredura a Laser (PVL) em pacientes glaucomatosos ou hipertensos oculares. Métodos: Trinta e sete olhos de 37 pacientes foram prospectivamente incluídos no estudo e

5. Rabies: ocular pathology.
Ocular pathology in the first European case of human bat-borne rabies is described. The patient was a 30-year-old bat scientist who seven weeks after bat bite developed neurological symptoms and died 23 days later. Rabies virus antigens were detected in brain smears. After extensive virological studies the virus turned out to be a rabies-related virus, close

6. Intraocular pathology of trisomy 18 (Edwards's syndrome): report of a case and review of the literature.
The ophthalmic histopathology is detailed in a case of trisomy 18 (Edwards's syndrome). In addition to the ocular pathology already reported, previously unreported findings of iris stromal hypoplasia, abnormal lens shape, and decreased ganglion cells in the retina are noted. The ophthalmic histopathology associated with this syndrome and the relationship of

7. Inactivation of the murine X-linked juvenile retinoschisis gene, Rs1h, suggests a role of retinoschisin in retinal cell layer organization and synaptic structure
Deleterious mutations in RS1 encoding retinoschisin are associated with X-linked juvenile retinoschisis (RS), a common form of macular degeneration in males. The disorder is characterized by a negative electroretinogram pattern and by a splitting of the inner retina. To gain further insight into the function of the retinoschisin protein and its role in the c

8. Vitreoretinal junction in infectious endophthalmitis in a primate eye.
A primate eye affected by postoperative infectious endophthalmitis was studied early in the course of the disease. Retinal perivasculitis, vitreoretinal adhesions along the inflamed vessels, and traction of the partially separated posterior vitreous on the retina at the adhesion sites were observed. It is suggested that such vitreoretinal junction pathology

9. Advanced glycation end products increase retinal vascular endothelial growth factor expression.
Advanced glycation end products (AGEs) are linked with the development of diabetic retinopathy; however, the pathogenic mechanisms are poorly defined. Vascular endothelial growth factor (VEGF) levels are increased in ischemic and nonischemic diabetic retina, and VEGF is required for the development of retinal and iris neovascularization. Moreover, VEGF alone

10. Massive proliferation of lens epithelial remnants after Nd-YAG laser capsulotomy.
Eight eyes exhibited massive proliferation of lens epithelial remnants following Nd-YAG posterior capsulotomy. All eyes had pre-existing retinal pathology. Six had undergone vitrectomy (four for proliferative diabetic retinopathy) before extracapsular cataract extraction with posterior chamber intraocular lens implantation. The other two eyes had familial ex

11. Effect of Anti-CXCL10 Monoclonal Antibody on Herpes Simplex Virus Type 1 Keratitis and Retinal Infection
The inflammatory response to acute ocular herpes simplex virus type 1 (HSV-1) infection in mice involves the innate and adaptive immune response, with an associated increase in the secretion of chemokines, including CXCL10 (interferon-inducible protein 10 kDa [IP-10]). Neutralizing antibodies to mouse CXCL10 were used to determine the role of CXCL10 during t

12. Prevention of ischemia-induced retinopathy by the natural ocular antiangiogenic agent pigment epithelium-derived factor
Aberrant blood vessel growth in the retina that underlies the pathology of proliferative diabetic retinopathy and retinopathy of prematurity is the result of the ischemia-driven disruption of the normally antiangiogenic environment of the retina. In this study, we show that a potent inhibitor of angiogenesis found naturally in the normal eye, pigment ep
