ABSTRACT

Abnormal head position is a compensatory condition which improves patients' vision. It can be caused by ophthalmological problems such as oculomotor imbalances (strabismus, nystagmus) and high astigmatism. However, it results in esthetic impairment, orthopedic trouble and facial asymmetries. We describe a case of a girl, JL, 8 years, with abnormal head position tilted to the left since the last glasses were prescribed. The correction used by the patient was: right eye = +2.00 sph diopter -5.5 cyl 180 degrees and left eye = +2.25 sph diopter -5.75 cyl 180 degrees. In tilted position, the correct visual acuity was: right eye 6/12 and left eye 6/9. No deviations were noted by the cover test and the remaining ophthalmological examination was completely normal. Retinoscopy under cycloplegia and subjective test showed right eye = +3.50 sph diopter -6.00 cyl 10 degrees; and left eye = +3.50 sph diopter -6.00 cyl 170 degrees, with visual acuity 6/6 in both eyes. With adequate prescription, the head position was normalized. Wrong cylindrical positions for correction of high astigmatism may cause abnormal head position. Retinoscopy under cycloplegia and subjective test are essential for precise diagnoses and prescriptions.

ABSTRACT

O objetivo do trabalho é relatar um caso de ectopia lentis et pupillae, chamando a atenção para as complicações oculares secundárias e seus diagnósticos diferenciais. Paciente de 27 anos com queixa de baixa acuidade visual. Não possuía características sindrômicas e os exames complementares realizados foram normais. No exame oftalmológico; acuidade visual de conta dedos a 2 metros em olho direito e conta dedos a 1 metro em olho esquerdo. Exotropia alternante de 25 dioptrias. Diâmetros corneanos de 10 mm e 9 mm nos meridianos horizontais e verticais, respectivamente. Ceratometria de 39,00 a 178° x 43,87 a 88° no olho direito e 37,64 a 22° x 42,75 a 112° no olho esquerdo. Na biomicroscopia, ambos os olhos apresentavam atrofia iriana, criptas ausentes e transiluminação de íris negativa. Pupila direita com forma regular e tópica, pupila esquerda também de formato regular, mas com deslocamento temporal inferior. Cristalinos opacificados, com tamanhos diminuídos e deslocados nasalmente. Pressão intra-ocular normal. Na ultra-sonografia, comprimento axial de 26 mm e 30 mm com diâmetro sagital do cristalino de 5,4 mm e 4,5 mm no olho direito e esquerdo, respectivamente. Os diagnósticos diferenciais incluem anormalidades puramente oculares, síndromes e distúrbios metabólicos. O diagnóstico dessa síndrome é importante para avaliação do risco, prognóstico e tratamento, além de ser fundamental seu conhecimento na diferenciação de outras síndromes nas quais há comprometimento sistêmico. A diminuição da acuidade visual é causada, geralmente, por desenvolvimento de grave miopia, catarata, astigmatismo corneano, descolamento de retina e glaucoma sendo justificável acompanhamento oftalmológico regular desses pacientes.

ABSTRACT

The main purpose of this report is to describe a case of ectopia lentis et pupillae syndrome, highlighting the secondary ocular complications and their differential diagnoses. A 27-year-old man presented with complaint of low visual acuity. No evidence of the syndrome was found at presentation. The results of supplementary tests were normal. On ophthalmologic examination, visual acuity was finger count at 2 meters in the right eye and finger count at 1 meter in the left eye. Exotropia of 25 dioptrics. Corneal diameters of 10 mm and 9 mm in the horizontal and vertical meridians, respectively. Keratometry readings of 39.00 at 178 x 43.87 at 88 for the right eye and 37.64 at 22 x 42.75 at 122 for the left eye. The biomicroscopic examination revealed iris atrophy in both eyes, absence of crypt and absent iris transillumination. Centralized right pupil with regular form and left pupil with inferior-temporal dislocation. Opaque lenses with reduced sizes and superior-nasal dislocation. Normal intraocular pressure. Axial length of 26 mm and 30 mm and crystalline axial diameter of 5.4 and 4.5 mm in right and left eyes, respectively, as revealed by ultrasonography. The differential diagnosis encompasses exclusively ocular abnormalities, syndromes and metabolic disorders. Diagnosis of the ectopia lentis et pupillae is fundamental not only to evaluate the risk, prognosis and treatment, but also to assist in differentiating other syndromes with systemic impairment. A visual acuity reduction is normally caused by severe myopia development, cataract, corneal astigmatism, retinal detachment and glaucoma, justifying regular ophthalmologic support for these patients.

ABSTRACT

Em crianças, as inflamações orbitárias idiopáticas são extremamente raras e de difícil diagnóstico. O presente trabalho tem por objetivo descrever um caso de inflamação orbitária idiopática aguda em criança de um ano e um mês de idade, que evoluiu com importante seqüela oculomotora. Além do estudo de caso, discute-se o diagnóstico diferencial entre a celulite orbitária e as inflamações orbitárias idiopáticas e faz-se uma revisão da literatura sobre a ocorrência das inflamações orbitárias idiopáticas na infância.
