SLT

SLT is an acronym that can refer to several terms across different domains. The two widely recognized meanings are Speech-Language Therapy and Selective Laser Trabeculoplasty. In some contexts, SLT may also stand for Sri Lanka Time or Sri Lanka Standard Time, the time zone used in Sri Lanka.

Speech-Language Therapy (SLT) is the professional practice of assessing, diagnosing, and treating communication and swallowing disorders. Practitioners, typically trained speech-language therapists or pathologists, work with individuals across ages—from toddlers with language delays to adults recovering from strokes. Interventions address speech sounds, language form and content, voice, fluency, cognitive-communication, and swallowing safety. Settings include schools, clinics, hospitals, and community programs. Goals focus on functional communication, social interaction, academic participation, and safe eating and drinking. Evidence-based approaches guide therapy, often involving multidisciplinary teams and families.

Selective Laser Trabeculoplasty (SLT) is an ophthalmic procedure used to lower intraocular pressure in glaucoma and ocular hypertension. A laser targets pigmented cells in the trabecular meshwork to improve aqueous humor outflow, reducing pressure within the eye. SLT is typically performed on an outpatient basis and can be used when medications are insufficient or poorly tolerated, or as a first-line adjunct. The number of treatments needed varies; some patients achieve lasting pressure reduction, while others may require retreatment years later. Possible risks include temporary IOP spikes, inflammation, discomfort, and, rarely, cataract or changes in vision.

Notes: In some medical, scientific, or scheduling contexts, SLT may be used to denote Sri Lanka Time, the time zone of Sri Lanka (UTC+5:30) year-round, with no daylight saving time.
