Study Notes
Retinal Detachment (RD)
- Accumulation of subretinal fluid causes separation of neurosensory retina from retinal pigment epithelium (RPE).
- Classified into three main types: rhegmatogenous, tractional, and exudative (serous).
Symptoms of Retinal Detachment
- Sudden onset of multiple floaters.
- Flashes of light in one or both eyes.
- Blurred vision and gradually reduced peripheral vision.
- Curtain-like shadow over the visual field.
- May be asymptomatic at times.
Risk Factors
- Higher prevalence in aging populations, particularly men.
- Extreme myopia increases the risk.
- History of retinal detachment in the fellow eye is a significant risk.
- Family history of RD and previous intraocular surgeries are contributing factors.
- Pre-existing retinal diseases, inflammatory conditions, or severe ocular injuries may predispose individuals.
Types of Retinal Detachment
- Rhegmatogenous RD: Causes include retinal breaks or posterior vitreous detachment (PVD).
- Tractional RD: Characterized by the retina being pulled away by tractional forces, often without tears.
- Exudative/Serous RD: Involves fluid accumulation often without retinal breaks.
Rhegmatogenous Retinal Detachment
- Occurs when vitreous flow behind the retina separates it from the RPE.
- Shafer’s sign (tobacco dust) indicates the presence of retinal pigment cells floating in the vitreous.
- Can result from operculated holes and peripheral horseshoe tears leading to extensive detachment.
Tractional Retinal Detachment
- Occurs due to tangential traction from scar tissue, leading to wrinkling and separation of the retina from the RPE.
- Conditions associated with tractional RD include proliferative diabetic retinopathy and other vascular and inflammatory disorders.
Exudative/Serous Retinal Detachment
- Fluid accumulation can arise from retinal or choroidal vascular sources.
- Causes include idiopathic origins, inflammatory conditions, infections, neoplastic issues, and vascular disorders.
- Notable conditions include Coats disease, VKH syndrome, and central serous chorioretinopathy.
Long-standing Retinal Detachment Features
- May show a pigmented demarcation line and subretinal fibrosis.
- Development of intraretinal cysts and neovascularization in the peripheral retina may occur.
Management of Retinal Detachment
- Treatment options include laser retinopexy, cryopexy, scleral buckle, pneumatic retinopexy, and pars plana vitrectomy.
- Surgical intervention has a high anatomical success rate, but visual outcomes can vary significantly depending on the timing and condition of the macula.
Retinoschisis vs. Retinal Detachment
- Retinoschisis involves separation within the neurosensory retina, leading to an absolute scotoma and a transparent dome-shaped appearance.
- Retinal detachment features separation from the RPE, relative scotoma, opaque appearance, and an undulating surface that changes shape during indentation.
Choroidal Detachment
- Can present as a smooth, bullous elevation of the retina, potentially extending 360 degrees.
- Types include serous and hemorrhagic, with serous detachment associated with conditions like hypotony, inflammation, and malignancies.
Management of Choroidal Detachment
- Conservative management focuses on underlying causes and may require medications like steroids.
- Surgical drainage may be necessary for persistent effusion leading to decreased vision or flat anterior chamber.
Uveal Effusion Syndrome
- Affects primarily middle-aged men, causing painless vision loss and significant choroidal elevation with normal intraocular pressure.
- Associated with high hyperopia and can result from impaired scleral permeability.
Hemorrhagic Choroidal Detachment
- Characterized by abrupt onset and severe pain, often linked to surgical complications, trauma, or spontaneous cases.
- High intraocular pressure (IOP) can occur, necessitating careful management.
