Specialist-led diagnosis and treatment for retinal conditions.
Retina
Retinal diseases refer to a range of conditions affecting the retina—the light-sensitive tissue at the back of the eye that is essential for vision—and include common disorders such as age-related macular degeneration (AMD), diabetic retinopathy, and retinal detachment, all of which can lead to partial or complete vision loss if left untreated. These conditions may affect central or peripheral vision and often present with symptoms like blurred or distorted vision, floaters, flashes of light, or sudden vision loss, although some may develop silently in the early stages.
Risk factors such as aging, diabetes, hypertension, and smoking further increase susceptibility, making regular eye examinations especially important. Diagnosis typically involves advanced imaging techniques like Optical Coherence Tomography (OCT) and retinal photography, while treatment options vary depending on the condition and severity, ranging from intravitreal injections and laser therapy to surgical procedures such as vitrectomy, all aimed at preserving vision, preventing progression, and managing underlying causes effectively.

FREQUENTLY ASKED QUESTIONS
You should seek immediate emergency eye care from a retina specialist if you experience:
- A sudden, dramatic increase in floaters (spots or cobweb-like specks).
- Repeated flashes of light in your side (peripheral) vision.
- A dark shadow or “curtain” moving across your field of vision.
- Sudden blurred or partial loss of vision.
Yes, medically necessary retinal treatments—including vitrectomy surgery, retinal laser therapy, scleral buckling, and intravitreal anti-VEGF injections for conditions like diabetic macular edema, age-related macular degeneration (AMD), or retinal detachment—are generally covered by major medical insurance policies. OasisEye Specialists works with a wide range of panel insurance providers, and our team can assist in verifying your policy benefits.
AMD affects the central part of the retina (the macula), leading to loss of sharp central vision.
- Dry AMD: The most common form, caused by gradual thinning of macular tissue and drusen buildup. It progresses slowly.
- Wet AMD: A more severe, rapidly progressing form where abnormal, fragile blood vessels grow under the macula and leak fluid or blood, requiring prompt intravitreal injections to prevent central blindness.
Intravitreal injections deliver anti-VEGF medications or steroids directly into the vitreous cavity at the back of the eye. Performed under local numbing drops in a sterile environment, these injections stop abnormal blood vessel growth, reduce fluid leakage, and relieve macular swelling caused by conditions such as wet AMD, diabetic retinopathy, and retinal vein occlusions.
A Vitrectomy is a specialized microsurgical procedure performed by a vitreoretinal surgeon to remove the gel-like vitreous humor from inside the eye. It is required to treat severe retinal conditions such as retinal detachments, macular holes, epiretinal membranes, non-clearing vitreous hemorrhages (bleeding in the eye), and advanced diabetic eye disease.
If a gas bubble is placed inside your eye during vitrectomy surgery to hold the retina in place while it heals, atmospheric pressure changes during air travel or high-altitude drives will cause the gas bubble to expand rapidly. This expansion leads to a severe, dangerous spike in intraocular pressure (IOP) that can cause intense pain and permanent vision loss. You must wait until the gas bubble completely dissipates naturally (typically 2 to 8 weeks) before flying.
High blood sugar levels over time damage the microscopic blood vessels in the retina. In early stages (non-proliferative diabetic retinopathy), these vessels swell and leak fluid, causing macular edema. In advanced stages (proliferative diabetic retinopathy), fragile new blood vessels grow on the surface of the retina, which can bleed into the eye or form scar tissue that causes tractional retinal detachment.
Retina specialists evaluate retinal conditions using high-resolution diagnostic tools, including:
- Optical Coherence Tomography (OCT): High-resolution cross-sectional 3D imaging of retinal layers to detect fluid, swelling, or macular structural changes.
- Fundus Fluorescein Angiography (FFA): Special imaging using a safe dye to highlight blood circulation and identify leaking or abnormal blood vessels in the retina.
- Dilated Retinal Examination & Fundus Photography: High-magnification direct visualization and photography of the entire retina.
