Objective: To evaluate the introduction of the femtosecond laser (FSL) to perform the key steps of the traditional cataract surgery process and the operational difficulties and safety of this new technology during routine use in an operating room in Brazil. Methods A retrospective study was conducted using the first cases operated on at a single center using the laser platform LenSx/Alcon with a soft contact lens patient interface.All patients underwent a detailed preoperative assessment.The anterior capsulotomy, nuclear fragmentation, and corneal […]

Purpose: To evaluate the changes of corneal biomechanical after femtosecond laser – assisted cataract and to compare the parameters derived by Corvis ST between standard phacoemulsification and femtosecond laser – assisted in cataract surgery Methods: This is a prospective study. 151 eyes of 127 patients were under went cataract surgery. 75 eyes of 65 patients were with femtosecond laser–assisted (FS)(Alcon Len Sx, Aliso Viejo,USA) and 76 eyes of 62 patients with standard phacoemulsification (SP) (Alcon Infinit, Fort Worth, USA). Lens […]

Objective: To determine the measurements of interpupillary distance (IPD) and ocular convergence in the presbyopic population with corneal reflex pupillometer. Methods: 160 subjects (66 males and 94 females) aged 41 to 85 years have their measurements of IPD done – far and near – by CRP method. Results: The mean age was 55.9 ± 11.5 years; the average IPD was 65.02 ± 2.78 and 62.47 ± 3.15 mm for male and female respectively. Also, the average convergence was 5.00 ± […]

The propose of this article is presenting a case report of Synchisis scintillans of the anterior chamber in an infant patient without any elucidation. The patient’s initial complaint was “strabismus since birth”. There was not found any other personal or family abnormalities. On examination: OS: Esotropia maintained, horizontal nystagmus, microphthalmia and leukocoria. OD: no abnormalities. Ultrasonography (USG) OS: reduction of the axial length, retinal applied and hyperechoic vitreous. Raised hypotheses were persistence of hyperplastic primary vitreous, congenital cataract and retinoblastoma, […]

The Christmas tree cataract is a rare type of lens opacification characterized by deposits of needle-shaped polychromatic cortex deep in the core, that can be isolated or associated with other opacities. We report and record, through photographs, two cases of this type of lens opacity.

The Holmes-Adie syndrome is characterized by the presence of tonic pupil associated with absence or diminution of deep tendon reflexes. In some cases there may be autonomous nerve dysfunction. The mechanism that causes the disorder is not fully known, but is believed to be caused by denervation of the postganglionic supply to the sphincter of the pupil and the ciliary muscle which can occur following viral disease. Typically it affects young adults and is unilateral in 80% of cases, although […]

A Síndrome de Holmes-Adie É caracterizada pela presença de pupila tônica associada à diminuição ou ausência dos reflexos tendíneos profundos. Em alguns casos pode haver disfunção nervosa autônoma. O mecanismo que causa a desordem não é totalmente conhecido, mas acredita-se que seja causada pela desnervação do suprimento pós-ganglionar para o esfíncter da pupila e para o músculo ciliar, que pode ocorrer após doença viral. Tipicamente afeta adultos jovens e é unilateral em 80% dos casos, embora possa se desenvolver no […]

The proximity of the orbital cavities to the air spaces of the face results in the occurrence of orbital infections resulting from sinusitis. Children with debilitated nutritional status are especially vulnerable. Clinically presents the inflammatory signs, and visual acuity deficit, diplopia, ophthalmoplegia and proptosis. Might also lead to severe complications such as cavernous sinus thrombosis and intracranial abscess. These infections can be classified according to their severity. Imaging tests of choice for the diagnosis and planning of cases include axial […]
