Background: Calcified band keratopathy is a chronic degenerative disease characterized by the deposition of gray to white opacity in superficial layers of the cornea that typically develops over months or years. It is associated with a variety of conditions, including chronic uveitis.
Purpose: The objective of this study is to assess visual acuity and corneal changes in patients with band keratopathy secondary to uveitis who underwent phototherapeutic keratectomy (PTK).
Setting: The place where this study was performed was in the Department of Ophthalmology and Visual Sciences, Federal University of Sao Paulo.
Design: This is a retrospective study.
Methods: Patients with uveitic band keratopathy were submitted to PTK. The PTK was performed using Allegreto Wave EX500, with the ablation area of 6 mm.
Results: Twelve patients (13 eyes) diagnosed with band keratopathy secondary to chronic uveitis were analyzed. Of the 12 patients, 8 patients were female (66 %), aged 22 years (7-53 years). From the 12 patients (13 eyes) evaluated in this study, only one patient (one eye) did not have visual improvement, due to epithelial deposits 2 weeks after PTK, and all the others benefited with the procedure. In the children group, all eyes had visual improvement, and quantitatively speaking, the children had a more significant improvement than adults.
Conclusions: PTK is a safe and effective procedure even for children. However, the improvement in visual acuity was restricted due to other ocular changes secondary to uveitis, such as cataract and retinal changes, or even the corneal irregularity.

Aim: To assess the utility and efficiency of endoscopy-assisted vitrectomy (EAV) for the treatment of corneal opacity in severe ocular trauma.
Methods: Patients who underwent fundus examination using a preoperative slit lamp and intraoperative endoscopy, followed by EAV and additional surgery were retrospectively recruited. Silicone oil removal and penetrating keratoplasty were used in selected eyes at postoperative follow-ups.

People with multiple sclerosis (pwMS) encounter numerous ocular complications, including uveitis. MS-related uveitis is linked to diverse complications, encompassing cataracts, cystoid macular edema, band keratopathy, glaucoma, retinal detachment, retinoschisis, vitreous hemorrhage, and occlusive vasculitis. The relationship between uveitis and MS is firmly established, but various prevalence rates have been reported.

Objective: To describe a case of presumed band keratopathy in a young cat with no known history of corneal disease who was not receiving topical phosphate-based steroids.
Animal Studied: A 10-month-old domestic shorthair cat was evaluated for severe ocular discomfort that did not improve despite the initiation of topical antibiotic treatment.
Methods: A complete ophthalmic examination and ancillary tests such as biomicroscopy and corneal cytology were performed at the time of presentation.
