________ Congenital glaucoma

Question

Quizplus · Accepted Answer

Absence or incomplete development of the scleral venous sinus results in congenital glaucoma or buphthalmos.This abnormality usually is caused by recessive mutant genes,but sometimes it results from a maternal rubella infection during early pregnancy.The embryological basis of blockage or incomplete development of the scleral venous sinus is abnormal persistence of mesenchymal tissue in the angle of the anterior chamber.As a result of inadequate drainage of the aqueous humor through the canal,intraocular tension rises,the eye gradually enlarges,and the cornea becomes hazy.Retinal damage causes visual impairment.
