The purpose of this study is to investigate the clinical characteristics of presenile cataract and compare that with ten years ago.
Materials and Methods
The subjects who received cataract surgeries aged from 30 to 54 years were recruited in Kaohsiung Chang Gung Memorial Hospital during September 2015 and August 2016. Patients with uveitis or those who received combined cataract surgeries were excluded. Retrospective chart review was performed in this study.
Results
A total number of 2439 cataract surgeries were performed and 302 (12.38%, 302/2439) eyes were presenile cataract.. Mean age was 47.6 ± 5.6 years old and mean axial length (AXL) was 26.00 ±2.89 mm. Among 302 presenile cataract eyes,the leading cause was high myopia (defined as AXL >=26mm, 47.02%), following by diabetes mellitus (26.82%). In types of lens opacity analysis, 67.55 % patients with nuclear sclerosis (NS) dominant. Compare to the previous study 10 years ago, the leading cause of presenile cataract
changed from idiopathic to high myopia, whereas the lens opacity types changed from PSCO dominant to NS dominant.
Conclusion
High myopia has been changed to be the most important clinical characteristic associated with presenile cataract, and the most common type of lens opacity was nuclear sclerosis. With the increasing prevalence of high myopia, we should pay more attention in manage of presenile cataract in highly myopes to avoid complications.
