Free floating pigmented vitreous cyst A 32‑years‑old female was referred for a mass in her left eye detected on routine examination. The ocular examination was normal with unaided visual acuity of 20/20 in her left eye. There were no signs of ocular trauma/inflammation. A  single, pigmented, free‑floating cyst was noted in the anterior vitreous [Fig. 1a and c] that showed speckled bright areas on infrared reflectance imaging [Fig. 1b]. In view of no symptoms, the patient was advised conservative management. These cysts have been reported rarely. These may represent choristoma of the hyaloid vascular system or may originate from ciliary epithelium. Acquired cysts can be found in association with retinoschisis, retinitis pigmentosa, trauma, coloboma, retinal reattachment surgeries and intraocular inflammation.[1,2] Though usually asymptomatic, vitreous cysts can disturb visual function when cyst floats into the visual axis. A period of observation should be recommended before invasive intervention in the form of laser cystotomy or vitrectomy.[3] Declaration of patient consent The authors certify that they have obtained all appropriate patient consent forms.

Choroidal vasculature without angiography A 21‑year‑old  albinotic female patient presented with history of nystagmus and poor vision since birth [Fig. 1]. Fundus examination revealed depigmented fundus and extensively visible details of choroidal vasculature. The wide‑angle images of the choroid showed predominance of veins draining into vortex veins, compared to arteries. The macula of both eyes showed a high density of choroidal venous plexus, compared to the venous density in the periphery. The finding of choroidal plexus at the macula could have implications in the understanding of pachychoroid diseases.[1-3] Declaration of patient consent The authors certify that they have obtained all appropriate patient consent forms.
