PURPOSE: To describe a particular form of posterior microphthalmos pigmentary retinopathy syndrome (PMPRS) with an atypical clinical presentation of pigment retinal dystrophy and an association to an inconstant complication which is angle-closure glaucoma (ACG). METHODS: A 40-year-old male patient with ACG on maximal topical treatment was referred to our department for uncontrolled intraocular pressure. Best-corrected visual acuity was 2/10 in the right eye and light perception in the left eye. Intraocular pressure was 36 mmHg bilaterally. He had 360° peripheral anterior synechiae on gonioscopy. Fundus examination revealed total cupping with pale retinal lesions in both eyes and a few pigment deposits in the midperiphery of the right eye. Multimodal imaging was done. RESULTS: Fundus autofluorescence revealed patchy areas of hypoautofluorescence. Optical coherence tomography (OCT) showed bilateral foveoschisis and macular folds. Anterior segment OCT showed a circumferential iridocorneal angle closure. Axial length measured with ultrasound biomicroscopy was 18.4 mm in the right eye and 18.1 in the left eye. Electroretinogram revealed attenuated scotopic responses. The patient was diagnosed with nanophthalmos-retinitis pigmentosa (RP)-foveoschisis syndrome complicated with ACG. A combined surgery with phacoemulsification - anterior vitrectomy - intraocular lens implantation and trabeculectomy was performed in both eyes with a satisfactory outcome. CONCLUSIONS: In its typical forms, PMPR syndrome is an association of nanophthalmos - RP - foveoschisis and optic nerve head (ONH) drusen. Incomplete phenotypes may lack ONH drusen or foveoschisis. Patients with PMPRS have to be screened for iridocorneal angle synechia and ACG.
