A 64-year-old man presented to the uveitis clinic to rule out masquerade syndrome in OS. His best-corrected visual acuity was hand movements. Anterior segment examination [Figure 1] revealed the presence of asteroid hyalosis in the anterior chamber and posterior chamber [Figure 2] with aphakic status. The reason for vision to not improve with +10 diopters could be concentration of asteroid bodies at the nodal point of OS and epi-retinal membrane.[1] OD examination was unremarkable. Records revealed eventful cataract surgery OS with posterior capsular rent rendering the patient apahkic. Although asteroid hyalosis is an uncommon finding (1%–2%);[2],[3] it can mimic intraocular tumor, metastasis, or endophthalmitis.[4]
