Corneal deposits associated with topical medications, particularly fluoroquinolones, are a recognized complication in ophthalmic practice. We present a case of a 66-year-old female with pseudophakic bullous keratopathy who developed corneal crystalline deposits following prolonged use of gatifloxacin and prednisolone eye drops post-penetrating keratoplasty. The patient presented with diminished vision and significant corneal opacity in the affected eye. Anterior segment examination and OCT imaging confirmed deposits extending from the epithelium to the anterior stroma. Management included corneal scrapping and transition to topical tobramycin and propylene glycol eye drops, resulting in the resolution of deposits and improvement in vision. This case underscores the importance of vigilant monitoring and judicious use of topical medications to mitigate adverse effects in high-risk ophthalmic patients undergoing corneal procedures.

Hepatolenticular degeneration, also known as Wilson's disease, is a type of autosomal recessive genetic disorder of copper metabolism. The causative gene, ATP7B, is located on the long arm of chromosome 13 and encodes a P-type ATPase that is involved in copper transport. Pathogenic mutations in the ATP7B gene sequence lead to the diminished or lost function of the ATP7B protein, resulting in pathological copper deposition in organs such as the liver, brain, kidneys, and cornea.

Wilson's disease is an autosomal recessive disorder that affects copper transport due to deficiency of ceruloplasmin and causes deposition of copper mainly in the liver, brain and cornea. It causes hepatic and/or neuropsychiatric manifestations. This copper deposition causes cirrhosis of the liver, encephalopathy and liver failure.

A young male in his late 20s presented with brownish discolouration of the conjunctiva and periocular area of both eyes. He was diagnosed as a case of lepromatous leprosy with recurrent type II lepra reaction 4 years ago and was started on multidrug therapy-multi bacillary, which included clofazimine. The best-corrected visual acuity was 20/20 in both eyes.

Purpose: In PAX6 syndrome, it is still not clear, whether prenatally, parallel to the iris tissue developmental anomaly, there is neural ectodermal, neural crest, or mesodermal cell deposition at the corneal endothelium, affecting endothelial structure and function. In addition, because of the postnatal corneal inflammation and commonly appearing secondary glaucoma, progressive endothelial changes are expected. Our purpose was to study the corneal endothelium in subjects with PAX6 aniridia, using in vivo confocal laser scanning microscopy.
