H33.311

Clinical Causes: Aging: As people age, the vitreous gel inside the eye can shrink or pull away from the retina, increasing the risk of tears. Previous eye trauma or injury: Any trauma to the eye can weaken the retina and predispose it to tearing. High myopia (nearsightedness): Individuals with severe nearsightedness have a longer eyeball, which can increase strain on the retina. Family history: A family history of retinal tears or detachments raises the likelihood of developing similar conditions. Previous eye surgeries: Surgeries such as cataract removal can sometimes alter the eye's structure, increasing risk. Vitreous detachment: When the gel inside the eye pulls away prematurely, it can cause tears in the retina. Other eye conditions or diseases: Conditions such as lattice degeneration or retinoschisis can predispose the retina to tears.

Key Symptoms: Sudden appearance of floaters — small spots or threads drifting through the field of vision. Flashes of light in one or both eyes, often more noticeable in the peripheral vision. Blurred vision or a shadow or curtain effect over part of the visual field. No pain typically occurs with a retinal tear, making early detection reliant on noticing visual changes. Sometimes, there is no noticeable symptom until the tear progresses or causes further problems.

Diagnosis Path: Visual acuity test to assess clarity of vision. Dilated eye examination: Eye drops are used to widen the pupil, providing a better view of the retina. Indirect ophthalmoscopy: A lamp and lens are used to examine the retina in detail. Ultrasound imaging: In cases where the view is obscured, such as with dense cataracts or vitreous hemorrhage, ultrasound can help visualize the retina.

Treatment Protocols: Laser photocoagulation: A laser is used to create small burns around the tear, creating scar tissue that seals the tear and secures the retina to the underlying tissue. Cryotherapy: A freezing probe applied to the outer eye surface to generate scar tissue around the tear. Close follow-up: Regular eye exams are necessary to monitor for any changes or developments that could lead to detachment. Prompt intervention: If the tear begins to enlarge or causes detachment, more invasive procedures like vitrectomy or scleral buckle may be considered.
