RESUMO
It is a congenital anomaly related to the persistence of the fetal hyaloidien system and hyperplasty of primary vitreous. The aim of our study is to analyze the epidemiological profile and the diagnostic and therapeutic difficulties of persistent hyperplastic primary vitreous. 13 children [15 eyes] with PHVP treated and followed between 2004 and 2012. Age at admission ranged from 3 months to 14 years. The main call sign was leukocoria in 69.23% of cases; unilateral in 84.6% of our patients. It was an anterior form in 13.3% of eyes, posterior in 6.66% and mixed in 80%. An indication for surgery was raised in 60% of eyes. The postoperative aphakia was corrected with an implant in 77.7% of operated cases. Therapy for amblyopia was performed in all patients. The best visual result: 2/10 and counting fingers in both anterior forms; 1/10 in a posterior form unoperated. Discussion This is an isolated and unilateral affection usually occurs in infants born at term, it is most often revealed by leukocoria. There are 3 clinical forms. The functional prognosis is poor and the PHPV depends on several criteria. Treatment should be tailored to the clinical form. All studies support the value of early diagnosis and early intervention to maximize the visual potential in selected patients. Vision therapy should not be neglected and started quickly in the postoperative period, with appropriate refractive correction of aphakia
RESUMO
Our study from January 1988 to May 1993 relates to 49 strabismic amblyopia records which represent 56 percent of strabismic children. The objective of this work is to insist on the interest of tracking down and early treatment of strabismic amblyopia because the therapeutic efficacy depend on the child age, and on the time between strabismus beginning and the treatment. The children age varied between 2 and 14 years. The strabismus was convergent in 44 cases, and divergent in 5 ones, with an oculary dominance in 90 percent of cases. The visual acuteness different between the two eyes was lower or equal to 4/10 in 26 cases and higher than 4/10 in 23 ones. Treatment consisted in an optic correction after cycloplegia and an amblyopia reeducation by occlusions of fixing eye with a variable frequency according to the age of the child and to the amblyopia deepness. The keeping treatment called for alternated occlusions over a right eye optic penalization. The functional recuperation after amblyopia reeducation is better among children group of 6 years [81,25%]
