Abstract Details

Purpose:

This is a retrospective study designed to understand the clinical demographic profile of patients with a diagnosis of keratoconus (KCN), presenting on their first visit to the clinic.

Setting:

L V Prasad Eye Institute, Hyderabad Tertiary Eye care centre India

Methods:

Retrospective review of electronic medical records of patients diagnosed with keratoconus between January 2016 to June 2019. The records of 6632 eyes of 3316 patients diagnosed with keratoconus were evaluated. Patients with post-LASIK ectasia, pellucid marginal cornel degeneration, keratoglobus were excluded. Patients with surgical intervention in any eye were excluded

Results:

Age and gender distribution showed 573 (17.3%) in (0-15years), 2327 (70.18%) 16-30 years, 406 (12.27%) >30 years, with Males (61.7%) and Females (38.3%) 729 (21.98%) seeked a second opinion for further management of keratoconus. 58 patients (1.7%) did give a positive family history of keratoconus. Ocular allergies were associated with 348 patients (10.2%). 1090 (32.87%) presented with unilateral keratoconus where in the central mean keratometry in one eye <46D and other eye >48 D, (558 right eye 51.19 % and 532 Left eye 48.80 %). However 1713 (51.65%)patients had asymmetric stage of keratoconus in both the eyes while 1603 (48.34 %) patients had symmetrical stages at presentation. 30 % patients with asymmetric presentation had an advanced stage (3 or 4) of disease in either of the eye while only 16% of the patients had advanced stage with symmetric presentation. On examination 149 patients had moderate and 111 had severe visual impairment in both the eyes while 47 presented with bilateral blindness. 989 (29.82%) were prescribed Contact lenses while 802 (24.18%) patients needed surgical intervention [770 (23.22%) CXCL, 20 DALK and 12 Penetrating keratoplasty].

Conclusions:

Understanding the variation in demographics and presenting pattern of keratoconus helps in planning treatment strategies and also assists in interpreting results published from different geographic locations. This study does show a difference in the presenting pattern of the disease compared to the published literature
