Slit-lamp examination showed vascularized corneal opacity with early band keratopathy with 360 degree limbal stem cell deficiency (LSCD) with cholesterol deposition over right cornea and vascularized corneal opacity from 7 to 4 o'clock position with cholesterol deposition and LSCD over left one.
Hypertension, band keratopathy, and acute pancreatitis were reported as well.
(8) While these crystalline deposits often do not cause visual impairment, in rare cases they may form band keratopathy, thus affecting the central cornea and reducing visual acuity.
SO associated keratopathy encompasses corneal odema, band keratopathy, bullous keratopathy, corneal thinning, retro-corneal membrane formation, and irreversible corneal endothelial cell loss9,12.
Different postoperative complications, such as silicone oil under conjunctiva, posterior capsule opacity, temporary ocular hypertension, iris and corneal neovascularisation, band keratopathy, postoperative mydriasis, and retinal redetachment, were observed in 5 patients (36%).
Limbal stem cell deficiency can present with clinical signs of persistent corneal epithelial defect, neovascularization, "Conjunctivalization," scarring, stromal ulcer, calcification, and band keratopathy. (4) The most common symptoms of limbal stem cell deficiency are decreased vision, photophobia, tearing, blepharospasm, recurrent pain, and redness.
Polyuria, excessive thirst and other manifestations like painful periarticular calcinosis, nephrocalcinosis, hypertension, renal failure or band keratopathy and hearing loss have been reported.
The patient's eye remained comfortable until the age of 38 years, when the patient started to have bilateral recurrent epithelial defects in the setting of band keratopathy and phthisis with associated pain and headaches.
JIA-associated chronic uveitis has a high frequency of serious complications: 20% develop cataracts, 19% glaucoma, and 16% band keratopathy. The anti-TNF biologics have all been tested in children with polyarticular JIA in blinded, placebo-controlled clinical trials, with over 70% in each trial demonstrating response that has been sustained in longer term follow-up studies.
If the concern with clarity is a focal opacity that is peripherally located, think of congenital conditions such as dermoid and sclerocornea, or acquired causes such as bacterial keratitis, the presence of a foreign body, and band keratopathy.
