Evaluation of Thermal Response of the Anterior Chamber of the Human Eye for Early Glaucoma Detection

Glaucoma is an irreversible eye problem that leads to vision loss. It is characterized by increased intraocular pressure (IOP) due to the accumulation of aqueous humor in the anterior chamber of the eye. This work evaluates the thermal response in the anterior chamber of the human eyeball when exposed to 694.3 nm Ruby LASER through the cornea for early glaucoma detection by using COMSOL Multiphysics simulation software. The thermal response of the aqueous humor revealed the presence of the liquid. Using a pulse duration of 0.5 ms, the thermal response was measured in both a normal and a glaucomatous eye model. The 694.3 nm ruby LASER showed a thermal response of 309 K in a normal eye and 306 K in a glaucomatous eye, as seen in Figure 3 and Figure 4. The results indicate that the 694.3 nm Ruby LASER, operating within the average human eye temperature range of 306.97 K to 308.56 K, is a safe and effective choice for glaucoma detection, causing no damage or significant physical changes to ocular tissues. The work shows that the 694.3 nm ruby LASER could be a useful tool for diagnosing glaucoma early in clinical settings.
