Scheimpflug‑based Optical Densitometry for Assessment of Corneal Opacity: An Objective Method to Monitor Interstitial Keratitis

Corneal optical clarity is essential for ocular function. Follow‑up evaluation is required in patients with interstitial keratitis (IK) to ensure appropriate dosage of densitometry; this could be used in a clinical setting and is valuable for research projects. In our experiment, a 34 year‑old male patient with herpetic IK [Figure 1] underwent Scheimpflug‑based densitometry, while being treated with 1% prednisolone acetate eye drop (Precord®, Sina Darou, Tehran, Iran) in order to monitor the corneal stromal haze. After 1 month of treatment, along with clinical resolution [Figure 2], the optical corneal density decreased [Figures 3 and 4].
