• The increased adoption of laser peripheral iridotomy (LPI), phacoemulsification with IOL, and minimally invasive glaucoma surgeries (MIGS) as frontline interventions is also accelerating market growth. These procedures offer effective intraocular pressure reduction with improved safety and recovery profiles.
• Simultaneously, advances in pharmacological therapy, including fixed-dose combinations and sustained-release drug implants, are improving patient adherence and treatment outcomes. The emergence of AI-assisted tele-ophthalmology platforms is further broadening access to diagnostics and specialist consultations, especially in underserved regions.

Restraint/Challenge

“Limited Access to Diagnostic Infrastructure and Post-Surgical Care in Developing Regions”

• One of the critical challenges restraining the growth of the angle-closure glaucoma market is the limited availability of specialized ophthalmic diagnostic equipment and trained eye care professionals in low- and middle-income countries (LMICs). Despite the high disease burden, many rural and underserved regions lack access to gonioscopy, AS-OCT, or laser therapy facilities, leading to delayed diagnosis and higher rates of blindness
  • For instance, large parts of Sub-Saharan Africa and South Asia still depend on basic visual acuity tests, which are insufficient for detecting angle closure in early stages. This lack of infrastructure limits the effectiveness of nationwide screening and early intervention programs
• Moreover, even where surgical interventions such as laser iridotomy are available, post-operative care and follow-up adherence remain inadequate due to systemic healthcare limitations and socioeconomic barriers. This results in suboptimal outcomes and persistent disease progression in many patients
• Another restraint is the lack of disease-specific therapies for certain PACG subtypes, where traditional open-angle glaucoma medications may not offer the same efficacy. In some cases, patients may experience poor response or side effects, highlighting the need for more targeted and PACG-specific drug development
• Overcoming these challenges will require greater investment in healthcare infrastructure, capacity-building for ophthalmologists, and affordable access to diagnostic tools and therapeutics tailored for high-prevalence regions
