What is Esotropia (Inward Eye Deviation)?

Esotropia accounts for the majority of childhood strabismus and is classified by age of onset, refractive status, comitancy and accommodation. Infantile (congenital) esotropia presents before 6 months with a large constant angle (>30 prism diopters), often associated with latent nystagmus, dissociated vertical deviation and inferior oblique overaction.

Accommodative esotropia typically develops between ages 1-5 due to uncorrected hyperopia and excessive accommodative convergence. Refractive accommodative esotropia normalizes with full hyperopic correction, while non-refractive accommodative esotropia (high AC/A ratio) may require bifocal glasses. Partially accommodative esotropia retains residual deviation despite glasses and often requires surgery.

Acquired non-accommodative esotropia and sensory esotropia (from monocular vision loss) require neurological evaluation when sudden, painful or accompanied by limited abduction (sixth nerve palsy). Treatment goals are normal alignment, binocular vision and stereopsis, and prevention of amblyopia. Modalities include glasses, prisms, botulinum toxin and extraocular muscle surgery.

Symptoms

Inward turning of one or both eyes
Constant or intermittent crossing
Eye fatigue with near work
Diplopia (double vision) — older children/adults
Squinting or closing one eye in bright light
Head turn to fixate with non-deviated eye
Reduced depth perception
Asthenopia (eye strain) and headache

Risk Factors

Family history of strabismus
Significant uncorrected hyperopia
Premature birth
Cerebral palsy or developmental delay
Down syndrome and other genetic disorders
Brain tumors or hydrocephalus
Monocular vision loss (sensory esotropia)
Sixth cranial nerve palsy

When to See a Doctor?

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

  • Persistent inward eye deviation at any age
  • Onset before 6 months — urgent referral
  • Sudden onset esotropia with diplopia
  • Esotropia with limited eye movement
  • Head turn or abnormal head posture
  • Failed strabismus screening
  • Family history with abnormal eye examination
  • Suspected neurological cause

Treatment Methods

01
Cycloplegic refraction and full hyperopic correction
02
Bifocal glasses for high AC/A ratio esotropia
03
Patching for amblyopia management
04
Prism therapy for small angle deviations
05
Botulinum toxin injection for selected cases
06
Bilateral medial rectus recession surgery
07
Adjustable suture techniques in older patients
08
Postoperative orthoptic therapy and follow-up

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.
