Purpose
To evaluate the demography, clinical characteristics, and risk factors of keratoconus (KCN) patients attending a tertiary eye centre in Kuala Lumpur, Malaysia
Setting
A hospital based population, single centre
Methods
This prospective cross-sectional study included KCN patients who visited Hospital Canselor Tuanku Muhriz, Universiti Kebangsaan Malaysia (UKM), between January 2022 and October 2023. Demographic details, best-corrected visual acuity (BCVA), clinical findings, refraction, and risk factors are recorded. We obtained topographical data and KCN classification using Oculus Pentacam (Wetzlar, Germany).
Results
Out of 71,862 outpatient cases, 78 newly diagnosed KCN patients were identified, with the majority having bilateral KCN (75.6%). The patients were 27.90 ± 7.37 years old on average and were predominantly male (55.1%) and Malay (70.5%). The KCN severity also varied between patients (12.8% mild, 43.6% moderate, and 43.6% severe). Patient's demographics showed no relationship with KCN severity (p > 0.05). Refraction showed BCVA of 0.39 ± 0.48 (LogMAR) and a mean spherical equivalent of -5.30 ± 4.45D. Eye rubbing (85.9%) and atopy (80.77%) were identified as the most common risk factors for KCN, contrary to family history (12.8%).Clinical presence of sub tarsal conjunctival papillae is noted in 68.7% of KCN cases.
Conclusions
KCN severity is independent of the demographics of patients. History of eye rubbing, atopy and sub tarsal conjunctival papillae were the most associated risk factors and vital characteristics for KCN screening.
