Purpose: The aim of this study was to evaluate corneal clarity in keratoconic patients using corneal densitometry.
Methods: comparing corneal densitometry results among keratoconic patients and normal individual was measured over a 12- mm diameter area, divided by annular concentric zones and depths. Keratoconus was classified according to the topographic keratoconus classification, from March 2019 to March 2020 in Ophthalmic center Mansoura University, Egypt.
Results: Group 1: 20 eyes diagnosed as manifest grade 1 keratoconus; Group 2: 20 eyes diagnosed as manifest grade 2 keratoconus; Group 3: 20 eyes diagnosed as manifest grade 3 keratoconus; Group 4: 20 eyes diagnosed as manifest grade 4 keratoconus; with 40 eyes normal topographic parameter a control group. the comparison between the studied groups regarding anterior (120 mm), central (from 120 mm to the last 60 mm) and posterior (last 60 mm) layers measurements showed increase in corneal densitometry reading in 0-2 mm, 2-6 mm, 6-10 mm, 10-12 mm zones in keratoconous patient and compared to control group, there was significantly increased in densitometry readings in keratoconous eyes and was related to keratoconous severity.
Conclusions: The densitometry readings increase in keratoconic eyes with higher values with increasing severity of keratoconus. Whitch may add valuable data for early diagnosis of keratoconus.
