<i><b>Aim</b>: to evaluate the utility of thermography in posterior scleritis (PS).</i>
</p>
<p>
<i>Patients and Methods: this prospective observational case-control study included 6 patients with monolateral PS (study group) and 10 healthy volunteers (control group). Ocular surface temperature (OST) was measured in all participants using a non-contact thermal camera (FLIR<sup>TM</sup>) integrated onto a smartphone (CAT S 60). The difference in OST between the affected eye and the healthy (fellow) eye on thermograms (Δt) <br>
was measured at each visit in both groups. Maximum (ΔtMax) and minimum (ΔtMin) Δt for each eye as well as the amplitude of fluctuations </i><i>(ampΔt) referred to as the difference between ΔtMax and ΔtMin were calculated for each eye. AmpΔt was compared between the groups.</i>
</p>
<p>
<i><b>Results</b>: in a total of 6 PS patients, B-scan ultrasonography revealed the thickening of the posterior sclera. Choroidal folds (n=4), internal limiting membrane fold (n=2), subretinal fluid (n=3), and optic disc edema (n=2) were identified by eye fundus exam. At presentation, Δt was maximum in all PS patients and reduced unequally after starting treatment. Mean ampΔt was 1.21 °C (1.47–1.04 °C) in PS group and 0.44 °C (0.13–0.63 °C) in the control group. 3 out 6 PS patients were diagnosed with recurrences as demonstrated by OST spikes compared to previous measurements.</i>
</p>
<p>
<i><b>Conclusion</b>: this article describes a novel technique of the measurement and monitoring of OST. It was demonstrated that PS is associated with the increase in OST measured by thermography. Further large-scale studies are needed to evaluate the potentialities of thermography for detecting occult or subclinical intraocular inflammation.</i>
