ANALYSIS OF AQUEOUS HUMOR PROTEINS IN MYOPIC PATIENTS

Abstract

Introduction: myopia is the most common eye disease in the world in with substantial social, educational and economic impact. Some studies have shown changes in aqueous humour proteins in myopic patients. To estimate total Aim: protein concentration, types of proteins in aqueous humour and the correlation with myopic patients. This is a Material and Methods: Prospective study conducted on 36 eyes of 36 patients attending Department of Ophthalmology, TRIHMS, Naharlagun, who were undergoing cataract operation. Group A served as a control group with 22 eyes of non myopic patients. Group B consisted of 14 eyes of 14 myopic patients having axial length more than 26mm.Aqueous humour collected from both the groups during cataract surgery was sent for Sodium dodecylsulfate polyacrylamide gel electrophoresis ( SDS-PAGE). Signicant diffe Result: rence in relative bands width (%) in the gel patterns in myopic and non myopic patient was seen.Myopic patients had higher magnitude of protein expressions /bands in molecular weights being 55kDa (Transthyretin), 69kDa ( Albumin) and 110kDa ( Vitamin-D binding protein) than non-myopic patients. In non myopic patients ,70-90 kDa (Heat shock Protein) were very highly expressed than myopic patients. Aqueous humour proteins were Conclusions: estimated to be different between myopic and non myopic patients signicantly. These proteins can be candidates for broadening of our existing knowledge of the pathophysiological characteristics of myopia. They may help in early diagnosis and monitoring of the myopic patients can be done. They may also help in deeper understanding of mechanism which cause axial elongation in myopia.
