Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to develop an educational program that will help improve the patients' understanding of what laser treatment is, how it might be beneficial to them, and why it should be the first eye pressure lowering glaucoma treatment to consider before the use of glaucoma eye drops.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Glaucoma is a disease characterized by optic nerve damage, visual field defects, elevated intraocular pressure (IOP) and progressive vision loss. More than 3 million Americans have glaucoma and more than 150,000 are blind as a result.

Regular use of glaucoma medications can usually lower intraocular pressure (IOP), prevent disease progression, preserve vision and prevent blindness. However, many people with glaucoma do not always use their medication as directed, with about one-third to one-half of patients with glaucoma not taking their drops as often as necessary, or have difficulty putting in the drops. There are also numerous local side effects from using glaucoma eye drops including red eyes, blurry vision and dry eye symptoms. Systemic side effects from eye drops range from triggering asthma, to lethargy and depression.

Selective laser trabeculoplasty (SLT) has been used safely and effectively for the treatment of elevated IOP in patients with open angle glaucoma for more than 20 years. SLT may result in mild and temporary IOP elevation, but this is a small risk and rarely significant. Other side effects include blurred vison and inflammation of the cornea (front, clear part of the eye), but they are extremely rare.

The purpose of this study is to develop an educational program that will help improve the patients' understanding of what laser treatment is, how it might be beneficial to them, and why it should be considered as first glaucoma treatment before the use of glaucoma eye drops.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Selective Laser Trabeculoplasty (SLT) Educational Intervention group (n=20) or Usual Care group (n=20). Knowledge, beliefs, barriers, and attitudes about SLT vs. medication as first line treatment of glaucoma will be assessed in both groups.

To evaluate barriers for widespread adoption of this procedure, we assessed beliefs and attitudes of ophthalmologists regarding SLT. We developed an educational slide presentation targeted at physicians to increase consideration of SLT earlier in glaucoma treatment paradigm.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Patient Educational Intervention group

Patients receive educational materials regarding selective laser trabeculoplasty (SLT) versus topical medication (ophthalmic eye drops) to lower eye pressure.

Group Type ACTIVE_COMPARATOR

Patient Educational Intervention

Intervention Type OTHER

Patients will respond to 5 questions regarding selective laser trabeculoplasty (SLT) versus topical medication to lower eye pressure. Then they will receive educational materials including 20 printed slides and view a 3 minute video on safety and efficacy of SLT. If patients agree to SLT, assistance in scheduling will be provided.

Usual care group

Patients receive standard of care.

Group Type PLACEBO_COMPARATOR

Usual Care

Intervention Type OTHER

Patients will respond to 5 questions regarding selective laser trabeculoplasty (SLT) versus topical medication to lower eye pressure. No other guidance will be provided.

Ophthalmologist Educational Intervention group

General ophthalmologists, ophthalmology residents, and glaucoma specialists in the Wills Eye Hospital physician contact database receive online survey and educational slide presentation regarding selective laser trabeculoplasty (SLT).

Group Type OTHER

Ophthalmologist Educational Intervention

Intervention Type OTHER

Responses to online survey regarding beliefs and attitudes towards selective laser trabeculoplasty (SLT) before and after educational slide presentation were recorded and compared between physician specialty groups.
