Abstract

Purpose: To study role of thermography in Posterior Scleritis (PS). Methods: Prospective, observational, case-control study. Clinically diagnosed cases of PS (n=6) and healthy controls (n=10) were studied. Ocular Surface Temperature (OST) was measured using a non-contact thermal camera (FLIR) integrated onto a smartphone (CAT S 60). Results: At presentation temperature difference between affected eye and healthy eye (Δt) was highest, which decreased variably in all PS cases during follow up. Mean amplitude of fluctuation of Δt in PS group and in control group was 1.21°C (range: 1.47- 1.04°C) and 0.44°C (range: 0.13-0.63°C) respectively. Three cases of PS had relapses and Δt showed spikes in OST compared to previous visits. Conclusion: We describe a new method to measure and monitor OST. Our study demonstrated increase in OST in eyes with PS. Further studies are needed to explore its usefulness in detection of occult ocular inflammation and differentiating PS from other entities.
