Glaucoma is a group of eye diseases that slowly damage the optic nerve, usually because of elevated pressure inside the eye (intraocular pressure, IOP). Over time this nerve damage reduces peripheral vision and can lead to irreversible blindness if not controlled. Many people with early glaucoma have no symptoms, which is why regular screening is critical, especially if they have risk factors like family history, high blood pressure, diabetes, or prolonged steroid use. AAO Mayo Clinic PMC
Cyclophotocoagulation (CPC) is a procedure used when standard treatments fail or are insufficient to lower IOP. It uses laser energy to partially destroy or modify the ciliary body, which is the part of the eye that makes aqueous humor (the fluid that creates pressure). By reducing its production, IOP falls. There are two main delivery methods: transscleral (through the white of the eye) and endoscopic (direct visualization from inside). CPC is often reserved for moderate-to-severe or refractory glaucoma, where other surgeries or medications have not achieved adequate pressure control. EyeWikiPMCAAO JournalAAO
Cyclophotocoagulation is a laser procedure that aims a concentrated beam of light at the ciliary body—the part of the eye that makes aqueous humour. By gently “spot-welding” tiny segments of this tissue, CPC slows fluid production, lowers intra-ocular pressure (IOP) and protects the optic nerve. When glaucoma has already damaged vision or refuses to respond to drops, tablets or filtering surgery, doctors often describe the situation in shorthand as “a CPC-level glaucoma.” Hence the mixed term “Cyclophotocoagulation Glaucoma” simply means a sight-threatening glaucoma serious enough to warrant laser destruction (photocoagulation) of the ciliary body. Modern studies confirm that CPC can cut eye-pressure roughly 30–50 % and trim the number of pressure-lowering medicines, especially in eyes with very high baseline IOP or after failed surgery. PubMed
Major TYPES
A. Ways to deliver the laser
Continuous-wave Trans-scleral Diode CPC (CW-TSCPC) – the classic method; heat is applied in 1.5–2 s bursts through the white of the eye. Safe but may sting and occasionally over-shut the eye leading to very low pressure. PubMed
Micropulse Trans-scleral CPC (MP-TSCPC) – the same diode energy chopped into micro-pulses that let tissue cool between pulses; lowers complication rates while preserving effect. PMCPubMed
Slow-coagulation TSCPC – uses longer exposure at lower power so tissue warms more gently; early data show greater IOP fall than micropulse with similar safety. The Open Ophthalmology Journal
Endoscopic Cyclophotocoagulation (ECP) – a miniature camera + laser inserted inside the eye lets the surgeon see and treat the ciliary processes directly; often combined with cataract or retinal surgery. PMCPubMed
High-intensity Focused Ultrasound Cycloplasty – not strictly a laser: uses ultrasonic rings to inactivate the ciliary body; research is ongoing but early results resemble diode CPC.
B. Kinds of glaucoma most often sent for CPC
Primary open-angle
Primary angle-closure (chronic or after acute attack)
Neovascular (due to diabetes or retinal vein block)
Uveitic or inflammatory
Traumatic
Congenital/pediatric refractory cases
Aphakic/pseudophakic (after lens surgery)
Post-keratoplasty (after corneal graft)
Steroid-induced
Glaucoma after retinal detachment repair
These labels simply flag the pathway that raised pressure; once routine care fails, any of them may reach the CPC stage.
Main causes
Inherited narrow drainage angle – eye structures are crowded, trapping fluid.
Age-related trabecular meshwork sclerosis – filter tissue stiffens and blocks flow.
Long-standing diabetes causing new blood vessels – fragile vessels close angles.
Central retinal-vein occlusion – retina starves, releases growth factors, same result.
Chronic uveitis – inflammation clogs the meshwork with cells and protein.
Penetrating or blunt eye trauma – scarring or pigment overload blocks outflow.
Prolonged steroid therapy (drops, pills, injections) – raises IOP in sensitive eyes.
Lens-related crowding (phacomorphic glaucoma) – swollen cataract narrows angle.
Pigment dispersion or pseudoexfoliation – debris from iris or lens clogs the filter.
Congenital malformations (e.g., Peters anomaly) – drainage canals never form well.
Post-corneal transplant angle damage – surgical scar distorts anatomy.
Thyroid eye disease – swollen muscles compress venous outflow, boosting IOP.
Obstructive sleep apnea – repeated low oxygen injures optic nerve, raises pressure spikes.
Severe eye infection (endophthalmitis) aftermath – scarring stiffens ciliary body.
Elevated episcleral venous pressure (Sturge–Weber, carotid-cavernous fistula) – outflow path backs up.
Tumour inside or behind the eye – mass effect hampers drainage.
Idiopathic intracranial hypertension spill-over – raises pressure through shared venous channels.
Sickle-cell disease ocular crisis – ischemia induces neovascular glaucoma.
Prior vitrectomy with silicone oil – oil blocks trabecular meshwork.
Failed filtering surgery with scarring – previous surgical route has closed; pressure rebounds.
Each cause gradually or suddenly lifts internal eye pressure. When drops, pills, laser trabeculoplasty, and shunts fail—or when pain becomes severe—CPC steps in to “switch off the tap” by disabling aqueous-producing tissue.
Symptoms
Blurred or hazy vision – first for distant objects, then constant.
Halos around lights – coloured rings, especially at night, from corneal swelling.
Eye or brow ache – dull pressure that painkillers seldom erase.
Sharp eye pain during spikes – felt suddenly, can wake patient from sleep.
Headaches on the affected side – radiate to temple or cheek.
Seeing rainbow colours on TV or phone screen – early corneal edema sign.
Intermittent red eye – engorged blood vessels when pressure surges.
Nausea or vomiting – vagal response to sudden high eye pressure.
Difficulty adjusting from dark to light – sluggish pupil and nerve fatigue.
Progressive “tunnel” vision – peripheral field shrinks.
Missing steps or bumping into door frames – unnoticed side-vision loss.
Reduced contrast sensitivity – blacks look grey; reading in dim light harder.
Eye tearing – reflex to surface irritation.
Photophobia – bright light worsens discomfort.
No symptoms at all until late – sadly common; optic nerve can die quietly.
Remember, pain often fades after CPC because pressure falls—but vision may not return if the optic nerve is already badly injured.
Further diagnostic tests
Physical-examination tools
Visual-acuity chart – baseline for future comparison; sudden drops warn of damage.
Pupil reaction (swinging-flashlight test) – detects a relative afferent pupillary defect signalling optic-nerve stress.
Goldmann applanation tonometry – the gold standard pressure reading; guides need for CPC.
Peripheral corneal thickness check (pachymetry) – thin corneas hide true IOP, thick ones overstate it.
Slit-lamp bio-microscopy – magnified look at cornea, iris, lens, and anterior chamber depth.
Gonioscopy – mirror lens shows the drainage angle directly; reveals synechiae or neovascular membranes.
Manual / bedside functional tests
Confrontation visual-field test – quick mapping of gross side-vision loss.
Amsler grid – looks for central distortion that may follow pressure spikes.
Color-vision plates (Ishihara) – optic-nerve damage dulls colour perception.
Digital palpation of globe firmness – simple squeeze test when tonometer is unavailable.
Laboratory & pathological tests
Complete blood count (CBC) – screens for anaemia or blood disorders linked to neovascular changes.
Erythrocyte sedimentation rate / C-reactive protein – high values suggest inflammatory or uveitic cause.
HbA1c and fasting glucose – poor diabetic control predicts neovascular glaucoma.
Thyroid profile – hyper- or hypo-thyroid states alter ocular pressure dynamics.
Autoimmune panel (ANA, HLA-B27) – looks for systemic diseases that inflame the eye.
Electro-diagnostic tests
Pattern electro-retinogram (PERG) – quantifies retinal ganglion-cell function; early indicator before field loss.
Visual evoked potential (VEP) – measures the speed of visual signals reaching the brain; delayed waves hint at optic-nerve compromise.
Imaging tests
Optical Coherence Tomography (OCT) nerve-fiber layer scan – high-resolution tissue map; thinning confirms damage.
OCT-angiography – shows micro-blood-flow drop around the optic disk; correlates with glaucoma stage.
Ultrasound biomicroscopy (UBM) – high-frequency ultrasound visualises ciliary body and verifies how much of it the laser treated.
Non-Pharmacological Treatments
Regular Physical Exercise: Moderate aerobic exercise (like walking or brisk walking) has been shown to lower IOP transiently and may improve ocular blood flow, helping slow progression in some patients. Mechanism: improved systemic and ocular perfusion, possibly affecting aqueous outflow dynamics. PMCEyeWiki
Weight Control / Healthy Body Mass: Obesity and metabolic dysfunction can influence vascular regulation around the eye. Maintaining a healthy weight supports overall cardiovascular health and may indirectly reduce glaucoma risk progression by optimizing ocular perfusion. EyeWiki
Sleep Hygiene and Positioning: Sleeping with the head slightly elevated can reduce nocturnal IOP spikes. Poor sleep or positions that increase venous pressure (like certain head-down yoga postures) can elevate IOP. Adjusting sleep habits is a preventive lifestyle measure. Verywell Health
Avoiding High-Risk Yoga Poses: Some yoga positions, especially those with head-down posture, can transiently raise IOP. Patients with glaucoma are advised to avoid or modify these to prevent pressure surges. Verywell Health
Smoking Cessation: Tobacco damages small blood vessels and can impair optic nerve perfusion. Quitting supports vascular health and may slow optic nerve damage. Jenkins Eye Care
Stress Reduction and Mindfulness: Chronic stress may affect systemic vascular tone; relaxation techniques might help stabilize systemic blood flow, indirectly benefiting optic nerve perfusion. (Inference based on vascular health principles; no strong direct trial data for glaucoma but consistent with recommendations for overall eye health.) Glaucoma Today
Tratak and Ocular Exercises: A traditional yogic eye-focusing exercise (Tratak) has preliminary evidence suggesting it may reduce IOP or help preserve retinal ganglion cells by promoting ocular muscle tone and perhaps improving microcirculation. Glaucoma Research Foundation
Avoiding Steroid Overuse: Systemic, topical, or periocular steroids can increase IOP, especially in steroid responders. Avoiding unnecessary steroid exposure is a preventative “non-drug” strategy. Eye Care Superior
Regular Eye Examinations: Early detection through scheduled comprehensive eye exams allows intervention before significant optic nerve damage. High-risk individuals need more frequent monitoring. Glaucoma Research Foundation
Blood Pressure and Diabetes Control: Hypertension and poorly controlled diabetes impair microvascular health and can worsen optic nerve perfusion; controlling these conditions supports glaucoma management. PMC
Hydration Awareness: Sudden large fluid intake can transiently increase IOP; patients are advised to drink fluids steadily rather than in large boluses. (Standard clinical advice inferred from IOP dynamics.) Glaucoma Today
Limiting Caffeine in Sensitive Individuals: High caffeine intake can cause small, transient increases in IOP in susceptible people; moderation is advised, especially if genetically predisposed. Verywell Health
Protective Eyewear: Preventing eye trauma avoids secondary glaucomas and preserves existing optic nerve function. Verywell Health
Optimizing Ocular Perfusion Pressure: Ensuring adequate blood pressure while avoiding extremes (especially nocturnal hypotension) helps maintain optic nerve health. This may include tailoring systemic antihypertensive timing. Glaucoma Today
Dietary Pattern (Whole Food Focus): Eating a balanced, nutrient-rich diet supports systemic vascular health and provides antioxidants that may add neuroprotection. Glaucoma TodayGlaucoma Research Foundation
Avoiding Dehydration: Severe dehydration can alter circulatory dynamics negatively impacting ocular perfusion; maintaining normal hydration supports stable IOP. (General physiological inference.) Glaucoma Today
Limiting Valsalva-Type Activities: Activities that sharply raise venous pressure (heavy lifting, straining) can transiently raise IOP; moderation or technique adjustment is reasonable. Verywell Health
Sunlight / UV Protection: While direct strong evidence in glaucoma is limited, protecting eyes from chronic oxidative stress with UV-blocking sunglasses supports overall ocular health. (General ophthalmic preventive principle.) Glaucoma Today
Avoiding Prolonged Head-Down Posture Outside of Yoga: Bending over for long periods can raise IOP; patients with glaucoma should be cautious with activities like gardening or heavy housework in low positions. Verywell Health
Patient Education and Adherence Support: Teaching patients about their disease, drop technique, and the need for consistent follow-up improves outcomes—non-pharmacological in that it is behavioral and systems-based. Glaucoma Research Foundation

Surgical / Procedural Interventions
Trabeculectomy
Procedure: Creates a new drainage channel under the conjunctiva to allow aqueous humor to exit the eye, lowering IOP.
Why Done: Standard surgical “gold standard” for open-angle glaucoma when medications fail; provides substantial and sustained IOP reduction.
Risks/Considerations: Bleb-related complications, infection risk, hypotony, bleb failure. PMCPMCGlaucoma Drainage Device / Tube Shunt
Procedure: Implantation of a device that channels aqueous humor from the anterior chamber to an external reservoir plate under the conjunctiva.
Why Done: Used when trabeculectomy is likely to fail or has failed, or in complex/refractory glaucoma.
Risks: Tube exposure, infection, over- or under-drainage. PMCMinimally Invasive Glaucoma Surgery (MIGS), e.g., iStent, Hydrus
Procedure: Small implants or procedures performed often at the time of cataract surgery to improve natural outflow with minimal tissue disruption.

Frequently Asked Questions (FAQs)
What is the difference between glaucoma and cyclophotocoagulation?
Glaucoma is the disease causing optic nerve damage, often from high eye pressure. Cyclophotocoagulation is a laser procedure used to lower that pressure by reducing fluid production. EyeWikiAAOIs cyclophotocoagulation a cure for glaucoma?
No. It lowers eye pressure to slow or stop progression, but it does not reverse existing optic nerve damage; ongoing monitoring is needed. PMCScienceDirectWhen is cyclophotocoagulation chosen over other surgeries?
Often when prior treatments have failed, in advanced or refractory cases, or when other surgeries are too risky or inappropriate. EyeWikiPMCHow effective is cyclophotocoagulation?
Many patients achieve meaningful pressure reduction, but some eyes may require retreatment; newer techniques like slow coagulation aim for more stable control. ScienceDirectWhat are the main risks of cyclophotocoagulation?
Inflammation, pain, vision fluctuations, need for repeat treatment, and in rare cases, vision loss. Endoscopic approaches may have fewer surface complications than transscleral. AAO JournalPMCCan lifestyle changes replace medications?
No; lifestyle supports therapy and may slow progression, but proven IOP-lowering medications remain the foundation. Glaucoma TodayGlaucoma Research FoundationAre supplements like ginkgo safe and effective?
Some show promise (e.g., ginkgo for blood flow), but evidence is mixed and they don’t replace standard care; they can have side effects and interactions. Glaucoma Research FoundationHealthHow often should someone with glaucoma be checked?
It depends on severity and risk: mild stable disease may be every 6–12 months, higher risk or progression more frequently—your ophthalmologist decides. Glaucoma Research FoundationWhat if my eye drops irritate my eye?
Talk to your doctor. Preservative-free formulations, changing agents, or adjusting technique can help. PMCCan exercise hurt glaucoma?
Moderate exercise is beneficial; avoid extreme head-down positions and heavy Valsalva that can spike IOP transiently. EyeWikiVerywell HealthIs vision lost from glaucoma reversible?
No. Damage is permanent; early detection and pressure control aim to prevent further loss. HealthWhat’s the role of MIGS versus traditional surgery?
MIGS offer safer, less invasive pressure lowering for early/moderate disease but usually less dramatic IOP reduction than trabeculectomy. ScienceDirectPMCCan I have cyclophotocoagulation in both eyes?
Yes, individually as indicated; treatment planning depends on disease severity and risk. (Standard clinical practice.) EyeWikiWill I need to stop my glaucoma medication after surgery?
Sometimes medications are reduced, but many patients continue some drops; it is personalized. PMCWhat should I do if I suddenly have severe eye pain with nausea?
Seek emergency care immediately—this may be acute angle-closure glaucoma, which can cause rapid vision loss. Cleveland ClinicMayo Clinic
Cyclophotocoagulation is a valuable tool for lowering IOP in difficult-to-control glaucoma, but optimal management combines accurate diagnosis, adherence to medical therapy, lifestyle and dietary support, consideration of supplements with caution, and timely surgical intervention when needed. Preventive vigilance, early detection, and patient education are foundational to preserving vision. Glaucoma Research FoundationGlaucoma TodayGlaucoma Research FoundationGlaucoma Research Foundation
