ABSTRACT
@#Climatic droplet keratopathy(CDK), an acquired corneal degenerative disease, is characterized by oil droplet deposits and banded opacity in the pre-corneal elastic layer and stroma layer, which can severely affect the visual acuity of patients. Recently, many studies have indicated that various factors caused the occurrence and development of CDK. However, the pathogenesis and specific pathogenesis of the disease remain unclear. So this article aims to summarize four aspects of the CDK, including the epidemiological characteristics, the morphology of corneal lesions, the composition of corneal deposits and the ocular surface micro-environment, and then provide a reference for ophthalmologists to acknowledge and explore CDK deeply.
ABSTRACT
Climatic droplet keratopathy (CDK) is one of the most frequent degenerative corneal diseases with high prevalence rates, especially in equatorial and polar regions. Th e profound hypoesthesia observed in some cases with advanced CDK may contribute to the occurrence of trophic-corneal ulceration, rapid bacterial over infection, diffi culty of healing and relentless evolution to perforation. Superfi cial keratectomy, lamellar or penetrating keratoplasty and excimer laser phototherapeutic keratectomy are various surgical options that have been tried in the management of CDK involving the visual axis, impairing the vision. We attempted conjunctivo-limbal autograft (CLAG) in a patient of advanced CDK with corneal ulceration and studied the outcome at the end of 6 weeks and found a better corneal epithelial regeneration post CLAG.
