The retina is a delicate tissue crucial for clear vision. A tear typically arises when the vitreous, the gel-like substance inside the eye, shrinks and tugs on the retina. Symptoms—though not always present—can include sudden flashes of light, new floaters, dark spots in vision, or a shadow in your peripheral vision. Without prompt treatment, tears may lead to retinal detachment, a serious and sight-threatening condition.
Diagnosis
Identifying a retinal tear begins with pupil dilation to allow a comprehensive retinal exam using specialised lenses. If necessary, techniques such as gentle eye indentation (scleral depression) or ultrasound are used to visualise the tear, particularly when view is obstructed by hemorrhage or blur.
Treatment options
Laser Photocoagulation
A laser creates a barrier of tiny burns around the tear to prevent fluid from seeping beneath the retina.
Cryopexy (Freezing Therapy)
A freezing probe is applied externally to seal the area around the tear, forming a stable scar.
These are quick, outpatient procedures designed to stabilise the tear and prevent progression. Recovery is generally straightforward, although heavy lifting and vigorous activities should be avoided briefly. Some small, symptom-free tears may be monitored without treatment if deemed safe.
