Microcornea, posterior megalolenticonus, persistent fetal vasculature, chorioretinal coloboma (MPPC) syndrome: Case series post vitrectomy

Abstract

Purpose

MPPC syndrome has been described as a syndrome that presents with chorioretinal coloboma, posterior megalolenticonus, persistent fetal vasculature, and chorioretinal coloboma. The purpose of our study is to report three patients who present with a variation of MPPC syndrome who each underwent pars plana vitrectomy, pars plana lensectomy, and amblyopic management. Clinical characteristics, ancillary test findings, and post-surgical functional results are compared to what is reported in the literature.

Methods

Retrospective review of medical records of patients who presented with microcornea, persistent fetal vasculature, chorioretinal coloboma, and microphthalmia who underwent surgical correction at Bascom Palmer Eye Institute.

Results

3 patients (6 eyes) were included, two males and one female. All patients were born full term, vaginally, and had no family history of genetic abnormalities affecting the eye. All patients had color fundus images, fluorescein angiography (FA) and echography. Four eyes underwent surgery. Following surgical intervention, patients demonstrated improved visual acuity, and improved functional status.

Conclusion and Importance

Patients with microcornea, PFV, chorioretinal coloboma, and microphthalmos, can benefit from surgical intervention when functional decline or media opacities are noted. Though difficult to assess accurate visual acuity and visual improvement pre-operatively and post-operatively, it is evident that our patients demonstrated improvement in functionality and vision following surgical intervention.
