Management of Glaucoma-Related Dry Eye Disease with Intense Pulsed Light: A Randomized Control Study

Area of Science:

• Ophthalmology
• Medical Technology
• Dry Eye Disease Research

Background:

• Glaucoma patients on hypotensive eyedrops often experience dry eye disease (DED).
• Untreated ocular surface disease can exacerbate DED progression in glaucoma patients.
• Intense pulsed light (IPL) therapy is being explored for ocular surface conditions.

Purpose of the Study:

• To evaluate the efficacy of intense pulsed light (IPL) therapy for dry eye disease (DED) in patients with glaucoma.
• To assess the impact of IPL on both subjective and objective measures of DED in this patient population.

Main Methods:

• A randomized control study involving 22 glaucoma patients (33-82 years) undergoing hypotensive eyedrop treatment.
• Participants received three IPL sessions on one eye, with the contralateral eye serving as a control.
• Key parameters like non-invasive tear breakup time (NITBUT), tear meniscus height (TMH), and OSDI were measured at baseline, week 2, and week 4.

Main Results:

• Significant improvements were observed in NITBUT, TMH, corneal staining, tear film lipid layer, meibomian gland expressibility, and OSDI scores in the IPL-treated eyes compared to control eyes (p<0.05).
• No significant changes were noted in other assessed parameters.
• Safety assessments including intraocular pressure (IOP), best-corrected visual acuity (BCVA), and corneal endothelial cell count (ECC) remained within normal limits.

Conclusions:

• Intense pulsed light (IPL) therapy demonstrates significant potential for improving both objective and subjective measures of dry eye disease (DED) in glaucoma patients.
• IPL therapy is a safe adjunctive treatment for managing DED in individuals with glaucoma.
• Addressing DED is crucial for glaucoma patients to prevent worsening of ocular surface disease.
