OBJECTIVES: To determine amblyogenic factors and amblyopia prevalence in a Health Family assisted community área of Lapa (RJ); and to estimate in the same area the sensiblity and specificity among visual acuity methods ( ETDRS versus LEA optotypes) in pre-school children. METHODS: Cross section study of 93 children from three to six years old. All the children were submitted to complete ophthalmological evaluation which included: anamnesis, ectoscopy, double blind visual acuity measurements with LEA and ETDRS optotypes, red reflex, Titmus […]

OBJECTIVE: This study evaluated the behavior of a population in relation to reading capacity considering font sizes of the texts with the objective of identifying minimum patterns accessible of font sizes. METHODS: Four hundred participants and their companions over the age of forty were interviewed at the state hospital Mário Covas of Santo André between 2007 and 2008.  They were given a reading test with five different font sizes. RESULTS: The majority (79.75%) reported having difficulty with reading.  Participants preferred larger font size among the […]

We demonstrate the combination of pseudophakic monovision technique with toric IOL in patients with relevant corneal astigmatism to reduce spectacle dependence after cataract surgery. All patients achieved UCDVA ³ 20/30 and UCNVA ³ J2 and none of them required spectacle correction on the 6th postoperative month.

Nós demonstramos a combinação da técnica de monovisão pseudofácica com lente intraocular tórica em pacientes com astigmatismo corneano relevante para reduzir a dependência de óculos após a cirurgia de catarata. Todos os pacientes apresentaram AVsc ³ 20/30 para longe e ³ J2 para perto, sendo que nenhum deles necessitou de correção ótica até o sexto mês pós-operatório.

Cornea intraepithelial dysplasias are lesions with low risk of malignancy within the spectrum of intraepithelial neoplasia of the ocular surface. These areas are presented as dysplasias or leukoplasias and are associated with the presence of human papillomavirus (HPV), a major risk factor. In this report, the authors describe a case of a corneal intraepithelial dysplasia treated by surgical excision, with histological confirmation and negative DNA hybridization for HPV.

X-linked juvenile retinoschisis is a hereditary and recessive vitreous-retinal disease. The main ophthamic manifestation is the bilateral macular cystic-like stellate maculopathy and splitting of the retina between the nerve fiber and ganglion cell layers. There were no treatments with efficacy in order to estabilize the visual acuity in the affected patients. This article presents a clinical case of a patient with a bilateral X- linked juvenil retinoschisis who was treated by the use of topical dorzolamide, a carbonic anhydrase inhibitor.

The cornea has a great influence in the visual process. However, it is liable to distortion, such as flattening. When this flattening is caused by the use of contact lenses, we call “corneal warpage”. In this case, some symptoms may occur as blurred vision with glasses, conjunctival hyperemia, foreign body sensation, etc… Used to think that the cornea was more rigid and, in time, realized that the cornea has viscoelastic properties. We can say that the cornea has a body […]
