photocoagulation is pronounced foh-toh-kaw-gyuul-AY-shuhn (/ˌfoʊtoʊˌkɔː.ɡjʊˈleɪ.ʃən/). It has six syllables (pho-to-coa-gu-la-tion), with the stress on "la". Photocoagulation is a medical procedure that uses focused light to coagulate tissue, typically retinal tissue, to seal leaks or destroy abnormal vessels. The term combines photo- (light) with coagulation (clotting), reflecting its mechanism. In practice, it involves directing a laser to targeted tissue to achieve hemostasis or controlled tissue destruction, often under local anesthesia.

"The patient underwent photocoagulation to treat a retinal tear."

"Photocoagulation is commonly used to manage diabetic retinopathy."
Break it into pho-to-co-ag-u-la-tion. Primary stress falls on the fourth syllable in many medical contexts: fo-to-co-AG-u-la-tion (IPA US: /ˌfoʊtoʊˌkoʊˌæɡjuˈleɪʃən/, UK: /ˌfəʊtəʊˌkəʊˌæɡjuˈleɪʃən/). Start with a short /foʊ/ or /fəʊ/ for photo, then /koʊ/ for co-, then /æɡ/ for -ag-, then /ju/ for -u-, and end with /leɪʃən/ as in -lation. Focus on the co- and -agu- clusters without excessive vowel reduction: keep /koʊ/ crisp, /æɡ/ clear, and deliver /ˈleɪʃən/ with a light secondary stress on -leɪ-. Audio reference tips: imagine saying ‘photo’ plus ‘coagulation’ briskly, but with de-emphasized vowels in unstressed positions. IPA cues: /ˌfoʊtoʊˌkoʊˌæɡjuˈleɪʃən/ US, /ˌfəʊtəʊˌkəʊˌæɡjuˈleɪʃən/ UK, adjust the final -tion to /-ʃən/.
Common errors: (1) Misplacing stress, blurring the -leɪʃən ending by saying /-lɒn/ or /-lɪən/ instead of /-leɪʃən/. (2) Slurring the -co- and -ag- as /koʊæɡ/ or /koʊəɡ/; keep the /koʊ/ and /æɡ/ distinct. (3) Incorrect vowel quality in /ˌfoʊtoʊ/ versus /ˌfəˈtoʊ/; use a longer first vowel for photo and a schwa-like second syllable in fast speech. Corrections: practice with targeted minimal pairs, emphasize /koʊ/ then clearly pronounce /æɡ/ and /ju/ before /ˈleɪʃən/. Use slow drills centering on /ˌfoʊtoʊˌkoʊˌæɡjuˈleɪʃən/ and gradually speed up.
US: tends to keep /ˌfoʊtoʊˌkoʊˌæɡjuˈleɪʃən/ with a rhotic /r/ not overtly present; UK: /ˌfəʊtəʊˌkəʊˌæɡjuˈleɪʃən/ with a clipped /əʊ/ and non-rhotic r; AU: often /ˌfōtōˌkōˈaɡjələˈɪʃən/ with slightly broader vowels and less pronounced /r/; overall rhythm remains similar, but coast through vowel qualities and consonant tightness vary. Emphasize /koʊ/ in US, /kəʊ/ in UK, and ensure /æɡju/ remains distinct in all. IPA references help track the subtle vowels and the rhotic vs non-rhotic differences.
It blends multiple morphemes with unfamiliar clusters: photo- /ˈfoʊtoʊ/ or /ˈfəˌtoʊ/, co- /koʊ/ or /kəʊ/, coag- /æɡ/ and -ulation /-leɪʃən/. The challenge is maintaining correct stress across a long word while preserving crisp syllables in fast clinical speech. The sequence /koʊæɡju/ requires precise placement of /æ/ before /ɡj/; misplacing stress can cause a stumble. Practice by chunking into meaningful units, then reassembling to a natural, medical cadence.
The -uation ending is not pronounced like ‘-uation’ with a strong /juː/; in many speakers, it fragments into /-juˈleɪʃən/ with a light /j/ glide before the /u/ and final /ʃən/. Also, the central syllable -co- commonly compressed in rapid speech, so you’ll hear more clearly /koʊ/ and /æɡ/ in careful speech. Remember the main feature is maintaining the /æɡ/ cluster cleanly before the /ju/ glide.

Photocoagulation derives from three morphemes: photo- from Greek photo- meaning light; coagulation from Latin coagulatio, from cohesus ‘coagulated’ plus -tion. The medical term coagulatio entered Latin medical usage in the late Middle Ages, referring to clot formation. The prefix photo- entered English in the 19th century with photographic and photophilic terms; in medicine, it combined with coagulation to describe light-induced clotting. The first known use in ophthalmology traces to early laser therapy explorations in the 1960s, with refinements in selective retinal photocoagulation by the 1970s–1980s. The word reflects both the mechanism (light-induced coagulation) and the targeted tissue effect (retina or other tissue). Over time, ‘photocoagulation’ has become a standard descriptor for laser-based tissue sealing and destruction techniques in ophthalmology and dermatology, signifying precision and controlled tissue response under illumination.
