Clinical Evaluation in Persistent Hyperplastic Primary Vitreous

ABSTRACT

We analysed a retrospective study of 23 patients (29 eyes) who were clinically and radiologically diagnosed as persistent hyperplastic primary vitreous from January 1984 to June 1992 at St. Mary's Hospital, Catholic University Medical College, by observing the clinical findings, results of CT or MRI, incidence of complications and postoperative visual acuity. The results were as follows 1. The unilateral ocular involvement was 73.9% and bilateral ocular involvement was 26.1%. 2. The common presenting clinical signs were shallow anterior chamber, lens opacity, vitreous opacity and microphthalmos. 3. The main features of CT or MRI were lens defcrmity, shallow anterior chamber, vitreous opacity and microphthalmos. 4. The complications were glaucoma (31.0%), intraocular hemorrhages (10.3%), posterior synechiae (17.2%) and phthisis bulbi (6.9%). 5. The postoperative visual acuity was not improved than preoperative levels.
