What is Advanced Glaucoma Filtration Surgery?

Glaucoma filtration surgery is performed when medical and laser therapy fail to control intraocular pressure. Trabeculectomy remains the gold standard; antimetabolites have improved success rates.

Tube shunts (Baerveldt, Ahmed, Molteno) are effective in complex glaucomas or after trabeculectomy failure. MIGS (iStent, Hydrus, XEN gel stent) provide minimally traumatic alternatives.

Surgical choice is guided by glaucoma type, target intraocular pressure and patient general status.

Symptoms

Uncontrolled high intraocular pressure

Medication intolerance

Progressive visual field defect

Optic nerve head cupping

Acute glaucoma attack

Congenital or juvenile glaucoma

Risk Factors

Family history of glaucoma

High myopia

Advanced age

Corticosteroid use

History of ocular trauma

Chronic inflammatory ocular disease

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

When intraocular pressure cannot be controlled
When the visual field is shrinking rapidly
When medication adherence is impossible
When acute pressure rise occurs
When prior surgery has failed

Treatment Methods

Visual field and OCT follow-up

Gonioscopy and pachymetry

Trabeculectomy with mitomycin C

Glaucoma drainage implant

MIGS procedures

Postoperative bleb management

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
