[A suggestion on the microsurgical treatment of the persistent hyperplastic primary vitreous body (PHPV) (author's transl)].

Three children suffering from PHPV are described, who originally had been sent to the hospital because of suspected retinoblastoma. Exstirpation of the PHPV after opening the anterior chamber with a corneal cut of 180 degrees under the microscope seems a recommendable treatment. The A. hyaloidea has to be observed carefully during the preparation. In order to avoid massive hemorrhage into the vitreous, it is necessary to ligate this vessel before cutting. The cosmetical results were good but the visual acuity was unsatisfactory. The problems arising after a successful operation of the PHPV are similar to those in children with unilateral cataract.

[The importance of the early diagnosis of primary persistent hyperplastic vitreous].

The early diagnosis of PHPV is often difficult to be established, because of the frequent opacification of the ocular transparent media. So the echography and the computerized tomography, the early surgical intervention using up-to-date techniques in vitreous surgery is imposed, in order to maintain functionally or anatomically the affected globe.

[Results of the surgical treatment in syndrome of primary persistent hyperplastic vitreous body].

Nineteen children with this syndrome aged 4 months to 15 years were treated. In case of a functioning hyaloid artery, the authors used an original surgical method. Visual functions were improved in 76.9% cases. In 23.1% cases vision acuity remained unchanged because of profound degenerative changes in the retina. Clinical results demonstrate the necessity of early surgery in children with the syndrome in question, because opening of the central retinal zone prevents the development of deprivation amblyopia.

[The use of A-scan echography in the clinical diagnoses of persistent hyperplastic primary vitreous (PHPV) (AUTHOR'S TRANSL)].

In 15 eyes with PHPV (3 suspected cases) patterns of rudimentary hyaloid vessels were found by A-scan echography in 9 cases all under 7 years of age; although these vessels were seen ophthalmoscopically in only 1 case. This ultrasonographic finding appears to add an important contribution to the clinical diagnosis of PHPV, when the monolateral cataract is so dense as to observe other signs (elongated ciliary processes, retrolental fibrovascular tissue). It could also be demonstrated that the axial diameter of the lens remains smaller than that of the partner eye even when the cataract is intumescent with fattening of the anterior chamber. Contrary to our expectations, the axial length of the bulbus was increased in one third of the cases; while a relative microcornea was absent only in 2 eyes!
