A case of tractional retinal detachment associated with congenital retinal vascular hypoplasia in the superotemporal quadrant treated by vitreous surgery Tomomi Miyamoto, Takatoshi Kobayashi, Teruyo Kida, Takaki Sato, Masanori Fukumoto and Tsunehiko Ikeda*
Abstract Background: Here we report a case of traction retinal detachment (TRD) associated with congenital retinal vascular hypoplasia localized in the superotemporal quadrant that was treated with vitrectomy. Case presentations: A 58 year-old female presented with a gradual decrease of visual acuity (VA) and distorted vision in her left eye. She had a past history of amblyopia in her left eye from early childhood, and a previous examination performed at a nearby hospital revealed that the corrected visual acuity (VA) in that eye was 0.15. Upon initial examination, no abnormal findings were observed in her right eye, yet optic-disc traction and macular rotation with a folded TRD extending superotemporally from the macular region was observed in her left eye. Fluorescein fundus angiography showed a retinal nonperfused area localized in the superotemporal quadrant surrounded by a retinal avascular area. The optic disc in her left eye was smaller than that in her right eye. Vitrectomy was performed to remove the proliferative membrane and created an artificial posterior vitreous detachment (PVD). Following surgery, the patient’s corrected VA improved from 0.04 to 0.1. Conclusions: The present case was likely to be TRD caused by PVD in the presence of localized congenital retinal vascular hypoplasia secondary to optic-disc hypoplasia.

Background Retinal diseases, such as retinopathy of prematurity (ROP) and familial exudative vitreoretinopathy (FEVR), are often accompanied by retinal vascular hypoplasia around the fundus [1, 2] and resultant displacement of retinal blood vessels and the macular region. Although these structures are usually pulled temporally or inferotemporally, a morphology can also be formed depending on the location of the retinal avascular area. * Correspondence: [email protected] Department of Ophthalmology, Osaka Medical College, 2-7 Daigaku-machi, Takatsuki City, Osaka 569-8686, Japan
Here we report a case of tractional retinal detachment (TRD) likely caused by age-related progression of posterior vitreous detachment (PVD) that was treated by pars plana vitrectomy (PPV) in a patient with optic-disc traction and macular rotation associated with optic-disc hypoplasia and congenital retinal vascular hypoplasia localized in the superotemporal quadrant.
Case presentation A 58-year-old woman presented to our hospital in May 2019 after becoming aware of a gradual decrease of visual acuity (VA) and distorted vision in her left eye.
