A 23-year-old male presented for a second opinion about an area of suspected spontaneous posterior capsular rupture (PCR) [* in [Figure 1]a and [Figure 1]b] in the right eye (RE). Inferonasal to the center of the lens, there was an opaque white membrane attached to the posterior lens surface (arrow) accentuating the appearance of PCR [Figure 1]c. There was a stalk [#, persistent fetal vasculature (PFV)] superonasal to this membrane going from the posterior capsule (PC) to the mid-vitreous, which moved like a “whiplash” during ocular movements [[Figure 1]d and Video 1]. The best-corrected visual acuity was 6/12 in the RE (−6.25/−1.50 @10), and 6/6 (−1.50/−0.75 @170) in the left eye (LE). There were laser spots around peripheral retinal holes in the RE and retinal lattice degeneration in the LE. There was a history of worse vision in the RE compared to LE since childhood. There was no history of ocular trauma or incisional ocular surgery. The anterior segment optical coherence tomography (ASOCT) showed a very thin yet intact PC with a membrane attached to it [[Figure 2]a, arrow]. The ultrasound biomicroscopy (UBM, 35 Hz) revealed an intact PC and retrolental membrane [[Figure 2]b, arrow] behind the central lens. Behind the peripheral lens, some of the membranes were noted to be attached to the pars plana [Figure 2]c. On review of the old records, the best corrected visual acuity and ocular condition seemed stable. The patient was advised regular follow-up.

The UBM scan through peripheral lens (c) showed some retrolental membrane, some of which were connected to the pars plana|

Our patient had unilateral high myopia (probably with lenticular component), anisometropic amblyopia, with PFV, and an apparent appearance of PCR in the RE. A PCR was ruled out using ASOCT and UBM. Our case may represent the unilateral myopic variant of PFV, which is associated with good visual prognosis, normal anterior segment dimensions (rather than usual microphthalmia), and is usually detected late. The retrolental membranes are a well-known feature of PFV.
