Diseases of the retina and optic nerve
The retina is the layer inside the eye that is responsible for perceiving light and transmitting images to the brain. The optic nerve (the nerve that connects the eye to the brain) transmits these signals.
Disease
Normal retina
Problems with the retina and optic nerve can be asymptomatic in the early stages, so early diagnosis is critically important.
The main conditions that can be diagnosed and managed:
  • Fundus changes are the area through which the condition of the retina and blood vessels of the eye is visible.
  • Degenerative processes are the gradual deterioration of the structure of the retina (for example, retinal dystrophy).
  • Inflammatory and vascular disorders – inflammation (for example, uveitis) or problems with blood circulation in the retina.
  • Glaucoma of the optic nerve is damage to the optic nerve due to increased intraocular pressure (glaucoma).
  • Congenital and acquired anomalies are structural features or acquired injuries (for example, injuries, consequences of diabetes).
Diagnostics
  • The goal: to identify diseases in the early stages, when there are no symptoms yet.

Methods and devices:
  • Ophthalmoscopy and biomicroscopy are examinations of the fundus and anterior segment of the eye through a special microscope.
  • Optical coherence tomography (OCT) is a high–precision device for scanning the retina and optic nerve, which allows detecting micro-injuries.
  • Fluorescent angiography is the introduction of a dye to assess blood flow in the retina.
  • Tonometry is a measurement of intraocular pressure, important for glaucoma.
  • Perimetry (field of vision) is a check of peripheral vision to detect damage to the optic nerve.
  • Diagnostic time: 30-60 minutes, including all examinations and a doctor's consultation.
Treatment
The goal: to stop the progression of the disease, preserve vision and eye functionality.
  • Medical treatment
    • Medications to reduce intraocular pressure (for glaucoma)
    • Intraocular injections to restore blood circulation and treat inflammation
    • Anti-inflammatory drops or systemic medications
  • Optical correction
    • Special glasses or contact lenses do not treat the retina, but they help with concomitant refractive disorders (nearsightedness, farsightedness, astigmatism).
    • Multifocal glasses or contact lenses help to distribute focus and reduce eye strain in adult patients with presbyopia.
  • Hardware treatment and therapy
    • Examples: Refrax or Amblyocore device (computer program).
    • What they do: they stimulate the retina and optic nerve, improve blood circulation, and train the "lazy eye" or binocular vision.
    • Why you need: comprehensive support after laser treatment or for chronic visual impairments.
  • Terms of treatment and adaptation:
    • Medications — course 1-3 months, regular checkups every 1-3 months
    • Long—term dynamics and control - 6-12 months or more, depending on the pathology
Dynamics control
  • Purpose: to monitor the condition of the retina and optic nerve, the effectiveness of treatment and timely adjust therapy.

Frequency of checkups:
  • Active therapy or progressive disease — every 1-3 months
  • Stable condition — every 6-12 months
  • What is being tracked:
  • Fundus changes
  • Condition of retinal vessels
  • Dynamics of the optic nerve and intraocular pressure
  • Reaction to treatment

Result

The main purpose of treatment and control:

  • Preserve your eyesight and visual acuity
  • Prevent serious complications (retinal detachment, vision loss in glaucoma)
  • Maintain the health of the optic nerve and retina
  • Provide comfortable and safe eyesight for many years to come
