Abstract:
OBJECTIVE:Intermittent exotropia (IXT) is the most common form of strabismus that warrants standardized management for better and predictable outcomes. Currently there are no preferred practice guidelines on the non-surgical management of IXT. Among the aforementioned methods, orthoptics is the most favored by optometrists and ophthalmologists based in China and Israel. However, consensus statements on the use of such modality are yet to be established. This study aimed to identify preferred non-surgical management strategies for intermittent exotropia (IXT) among members of the Philippine Society of Pediatric Ophthalmology and Strabismus (PSPOS).
METHODS:The survey collected data on respondent and patient demographics, perceived causes of IXT, clinical course, and management preferences. Incomplete responses were excluded, and data were analyzed using frequency distribution and the Fisher test.
RESULTS:Forty of 54 (74%) PSPOS members participated, predominantly from urban settings (34 respondents). Most IXT cases were children aged 4 to 11 years. The proportion of pediatric patients was not significantly influenced by respondents’ age (p=0.1628) or practice region (p=0.451). Twenty-one (52.5%) respondents cited fusion defects as the primary cause of IXT. While twenty-one noted an unpredictable course, 14 identified it as a progressive course. Overminus lenses were preferred for younger patients (1-4 years), with an increasing preference for orthoptics in older age groups (5 to>18 years). Pediatric ophthalmologists aged 30 to 40 years (p=0.005) and those with 1 to 5 years of experience (p=0.020) favored overminus lenses for 5-10-year-olds. Preference for overminus lenses was stronger outside the NCR (p=0.044). Furthermore, 90% of respondents said surgery shouldn’t be performed at diagnosis, and 42.5% of respondents were against it for younger ages.
CONCLUSION:The findings revealed a strong preference for overminus lenses among PSPOS members, with increasing use of orthoptics for older patients. Factors influencing management decisions included respondent age, practice region, and perceptions of IXT’s cause and course. Future randomized controlled trials are essential to evaluate non-surgical interventions and develop comprehensive treatment guidelines. - Full text:2025010610323035688UERM3.pdf
