An 88-year-old male presented with diminution of vision since 7 months following laser posterior capsulotomy in the right eye (RE). He was a known case of bilateral open-angle glaucoma on topical medications. His visual acuity was hand movements in RE and intraocular pressure was 14 mmHg. On examination, there were fine calcium-like deposits on the corneal endothelium, denser inferiorly, diffuse stromal edema, well-centered posterior chamber intraocular lens (PCIOL), and posterior capsulotomy opening without any vitreous in the anterior chamber (AC) [Figure 1]. Fundus examination showed asteroid hyalosis (AH) in RE and bilateral advanced glaucomatous cupping. Anterior segment optical coherence tomography of RE showed hyper-reflective deposits on corneal endothelium with diffuse stromal edema [Figure 2]. Specular microscopy of RE could not be obtained, while the left eye (LE) showed polymegathism and pleomorphism [Figure 3]. The patient refused any surgical intervention and was managed conservatively. At the last follow-up of 5 months, he had additionally developed ocular surface problems with resultant central stromal opacities and hypertrophic epithelium [Figure 4].

| Discussion|| |
AH is a condition where yellow-white refractile particles, called “asteroid bodies,” are found inside the vitreous cavity. It is commonly unilateral, male-predominant, and associated with increasing age after the sixth decade. Prolapse of asteroid bodies into the AC following uneventful cataract surgery has been reported only twice in the literature., We believe that, in our case, the asteroid bodies partially seeped into the AC through the capsulotomy or a pre-existing area of zonular dehiscence that got disturbed during capsulotomy. Benzalkonium chloride (BAK), a common preservative in glaucoma medications, causes corneal toxicity and subclinical AC inflammation. These factors could have contributed to a compromised endothelium leading to the adherence of the asteroid bodies. To the best of our knowledge, this is the first reported case of endothelial adherence of asteroid bodies following laser posterior capsulotomy.
