    Purpose: To evaluate the genetic aspects of strabismus. Methods: Ophthalmic and orthoptic evaluations were performed prospectively on 110 strabismic probands and 478 relatives. We used 3 different criteria in the diagnosis of strabismus: primary diagnosis (dx1) defined as any manifest horizontal or vertical deviation, a secondary diagnosis (dx2) including esophoria (>7 prism diopters) or exophoria (>9 prism diopters), and a tertiary diagnosis (dx3) including abnormal fusional amplitudes, accommodative convergence/accommodation (AC/A) ratio, and/or stereopsis; monofixation syndrome; 4 prism diopters base out; and/or abnormal Maddox test responses. Analyses were carried out within mating types. Results: Hypotheses of autosomal dominant or recessive inheritance with no sporadics were rejected. Based on the dx1, 25% of the families had more than one individual affected and there was vertical transmission in 13%; adding dx2 there were 36% of the families with more than one affected and 21% had vertical transmission; and adding dx3, there were 73% with more than one affected and 51% with vertical transmission. Conclusions: There is evidence for a pattern consistent with an autosomal dominant form of strabismus in most families.

    Reoperação nas esotropias congênita e essencial adquirida não acomodativa
    (Conselho Brasileiro de Oftalmologia, 2011-06-01) Ejzenbaum, Fábio [UNIFESP]; Marques, Adele Christina Manso; Ferreira Pinto, Janine Radd; Souza-dias, Carlos Ramos; Goldchmit, Mauro; Universidade Federal de São Paulo (UNIFESP); Santa Casa de São Paulo Faculdade de Ciências Médicas Departamento de Oftalmologia
    PURPOSE: To analyze the results in patients reoperated from congenital and essential esotropia. METHODS: A retrospective chart review of 393 patients who underwent surgery from 2000-2004 was performed. Subjects were divided into two groups: Congenital esotropia (91patients) and essential esotropia (302 cases). RESULTS: Among congenital cases we had 9 reoperations (9.9%). There were undercorrections (3.3%), overcorrections (2.2%), anisotropia (V) (1.1%), hypotropia (1.1%) and dissociatd vertical divergences (2.2%). Among the essential cases, there were 31 (10.3%) reoperations due to undercorrections (n=6.6%), overcorrections (n=2%) and hypotropias (1.7%). CONCLUSIONS: Outcomes reoperations rates were 9.9% and 10.2% between congenital and essential esotropias with a higher rate of undercorrections. Amblyopia in both groups and deviations higher than 50∆ in essential esotropias seems to be the most important factors for poor results.

    Técnicas cirúrgicas para correção da presbiopia em pacientes fácicos
    (Conselho Brasileiro de Oftalmologia, 2004-06-01) Ferraz, Caroline Amaral [UNIFESP]; Allemann, Norma [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Presbyopia is characterized as a progressive age-related loss of accommodative amplitude. In recent years, attempts have been made to surgically reverse presbyopia. This article discusses different procedures proposed for treatment of presbyopia in phakic patients.
