Retinal detachment (RD) is a true ophthalmologic emergency in which the neurosensory retina separates from the underlying retinal pigment epithelium, leading to progressive, irreversible vision loss if not promptly treated. [1-2] The most common type is rhegmatogenous retinal detachment (RRD), with an annual incidence of approximately 10 per 100,000 and a peak in the 6th–7th decades of life. [2-3] It is twice as common in men. [2]
1. History
- Classic triad: Unilateral photopsias (flashing lights) → new floaters → progressive visual field defect ("curtain" or "shadow") [1-2][4]
- Onset is typically acute and painless; pain suggests an alternative diagnosis [2][5]
- Flashes are often in the peripheral visual field and may precede floaters by hours to days [4]
- Floaters may be described as "cobwebs," "spots," or a "shower of dots" (suggesting vitreous hemorrhage from a torn retinal vessel) [6]
- The visual field defect is progressive — starts peripherally and enlarges over days; central acuity drops abruptly when the macula detaches [1][6]
- Ask about timing of symptom onset, laterality, and whether central vision is affected (macula-on vs. macula-off — critical prognostic distinction) [1]
- Important negatives: no pain, no photophobia, no redness, no discharge
2. Alarm Features
- Progressive monocular visual field loss (curtain/shadow defect) — the primary red flag for RD vs. benign posterior vitreous detachment (PVD) [4]
- Sudden decrease in visual acuity (suggests macular involvement) [1]
- Sudden increase from <10 to ≥10 floaters (LR 8.1–36 for retinal tear in patients with known PVD) [4]
- Vitreous hemorrhage (shower of dark floaters, decreased red reflex) [4]
- Pigmented cells ("tobacco dust" / Shafer sign) in the anterior vitreous — highly suggestive of retinal tear [7]
- Any visual field defect on confrontation testing [4]
3. Medications
- Fluoroquinolones (oral): An early nested case-control study reported a 4.5-fold increased risk of RD with current use. However, more recent and larger studies, including a 2024 JAMA Ophthalmology self-controlled case series and cohort study, found no significant association after adjusting for confounders (pooled aRR 1.15, 95% CI 0.86–1.54 for 1–29 days post-exposure). A 2024 large-scale retrospective cohort across Taiwan and US databases also showed comparable RRD risk between fluoroquinolone and comparator antibiotic users (HR 0.97, 95% CI 0.76–1.23). The association remains debated; moxifloxacin has the strongest signal among individual agents. [8-11]
- Anticoagulants: May increase risk of vitreous hemorrhage, which can accompany or mimic RD [2]
- Miotics (pilocarpine): Can theoretically increase vitreoretinal traction
- No specific medications treat RD; management is surgical
4. Diet
- No specific dietary triggers or recommendations for RD
- Adequate hydration and nutrition support general postoperative recovery
- Patients with diabetic retinopathy (a risk factor for tractional RD) benefit from glycemic control and dietary management of diabetes
5. Review of Systems
- Ophthalmologic: Flashes, floaters, visual field defects, decreased acuity, prior eye surgeries, corrective lens history (myopia)
- Neurologic: Headache, other visual phenomena (to distinguish from migraine aura, which is bilateral and lasts 15–60 min)
- Constitutional: Fever, weight loss, night sweats (if considering exudative RD from inflammatory/neoplastic causes) [2]
- Rheumatologic/Autoimmune: Joint symptoms, skin rashes (posterior uveitis, Vogt-Koyanagi-Harada)
- Vascular: History of amaurosis fugax, TIA symptoms (to distinguish from retinal artery occlusion) [2]
6. Collateral History and Family History
- Family history of retinal detachment is a recognized risk factor [1-2]
- Hereditary connective tissue disorders: Marfan syndrome, Stickler syndrome, Ehlers-Danlos syndrome — all associated with increased RD risk [9]
- History of RD in the contralateral eye significantly increases risk [1][12]
- Collateral from family regarding timeline of symptom onset and progression is helpful if the patient is a poor historian
7. Risk Factors
- Age ≥50 years (peak 60–70 years) [1][7]
- Myopia (especially high/pathologic myopia; 15–200× increased lifetime risk) [7][12]
- Prior cataract surgery (0.26%–4% risk of subsequent RRD; incidence has increased with rising cataract surgery rates) [7][13]
- Ocular trauma (blunt or penetrating) [1][6]
- Previous RD in the contralateral eye [1][12]
- Lattice degeneration (present in 6%–8% of the general population, ~30% of phakic RRDs) [12]
- Family history [1]
- Diabetes (proliferative diabetic retinopathy → tractional RD) [2]
- Male sex (2:1 male predominance) [2]
- Posterior vitreous detachment (most frequent precipitant; 14% of symptomatic PVDs develop a retinal tear) [1][13]
8. Differential Diagnosis
- Posterior vitreous detachment (PVD): Most common cause of acute floaters/flashes; benign but 14% develop retinal tears — the key differentiator is the absence of visual field defect [1][4]
- Vitreous hemorrhage: Sudden shower of floaters, decreased vision, loss of red reflex; may coexist with or mask RD [4][14]
- Central/branch retinal artery occlusion: Sudden painless monocular vision loss, but onset is over seconds (not progressive), RAPD present, cherry-red spot on fundoscopy [1-2]
- Central/branch retinal vein occlusion: Painless vision loss with retinal hemorrhages on fundoscopy
- Migraine with aura: Bilateral scintillating scotoma lasting 15–60 min, followed by headache; resolves completely
- Acute angle-closure glaucoma: Painful, red eye with mid-dilated pupil, elevated IOP — distinct from painless RD [2]
- Optic neuritis: Pain with eye movements, RAPD, color desaturation [2]
- Exudative (serous) RD: No retinal break; caused by inflammatory, vascular, or neoplastic conditions [13][15]
9. Past Medical History
- Prior retinal detachment or retinal tears (highest risk for recurrence)
- Prior cataract surgery or other intraocular surgery [1][13]
- History of myopia and degree of refractive error [2]
- Ocular trauma history [6]
- Diabetes mellitus (proliferative diabetic retinopathy) [2][4]
- Connective tissue disorders (Marfan, Stickler) [9]
- Inflammatory eye disease (uveitis)
- Glaucoma [13]
10. Physical Exam
- Visual acuity: May be 20/20 if macula is spared; significantly decreased if macula is detached [1-2]
- Confrontation visual fields: Peripheral scotoma corresponding to the area of detachment (e.g., superior detachment → inferior field defect) [1-2]
- Pupillary exam: Usually normal; RAPD may be present with extensive detachment [2]
- Dilated funduscopic exam: Elevated, opaque, furrowed-appearing retina that may ripple with eye movements; transparent subretinal fluid. Peripheral tears may be difficult to see with direct ophthalmoscopy [2][7]
- Slit lamp exam: Look for pigmented cells ("tobacco dust"/Shafer sign) in the anterior vitreous — highly suggestive of retinal tear [7]
- Intraocular pressure: May be slightly lower in the affected eye
- Red reflex: May be diminished or absent with vitreous hemorrhage
11. Lab Studies
- No routine labs are required for the diagnosis of RD
- If exudative RD is suspected, consider:
- ESR/CRP (giant cell arteritis, inflammatory causes)
- CBC, ANA, ACE level, RPR/FTA-ABS (uveitis workup)
- HbA1c (diabetic retinopathy assessment)
- If central retinal artery occlusion is in the differential: ESR, CRP, lipid panel, glucose [1]
12. Imaging
- First-line: Ocular point-of-care ultrasound (POCUS) — 97% sensitivity for RD in the ED; shows a hyperechoic membrane tethered to the optic disc. Particularly useful when fundoscopy is obscured by vitreous hemorrhage or cataract. [1][14-15]
- Gold standard: Dilated funduscopic examination by ophthalmology (with indirect ophthalmoscopy and scleral depression) [15]
- Optical coherence tomography (OCT): Used by ophthalmology to assess macular involvement
- CT/MRI orbit: Not typically needed for RRD; may be indicated for exudative RD to evaluate for choroidal mass or other underlying pathology [15]
- Imaging is unnecessary when the diagnosis is clinically obvious on dilated exam [15]
The following figure demonstrates the characteristic POCUS appearance of retinal detachment (Panel A), vitreous detachment (Panel B), and vitreous hemorrhage (Panel C):
13. Special Tests
- Ocular POCUS: High-frequency linear probe (7.5–10 MHz) placed over the closed eyelid with gel; look for a bright, tethered membrane in the posterior chamber that does not cross the optic disc (distinguishes RD from PVD, which is freely mobile and not tethered) [14]
- Amsler grid: Detects central visual field distortion (metamorphopsia) if macula is involved
- Seidel test: If trauma is suspected, to rule out globe perforation
- Tonometry: IOP may be slightly lower in the affected eye; also rules out acute angle-closure glaucoma
14. ECG
- ECG is not indicated for retinal detachment itself
- ECG is relevant when central retinal artery occlusion is in the differential, as part of the stroke/embolic workup (echocardiography, ECG, carotid ultrasound) [1]
- If a patient with visual symptoms has concurrent cardiac symptoms or vascular risk factors, ECG may be warranted to evaluate for atrial fibrillation or other embolic sources
15. Assessment
Retinal detachment is an ophthalmologic emergency. The critical clinical distinction is:
- Macula-on RD: Macula still attached — best visual prognosis; 75% achieve ≥20/40 final acuity. Requires urgent/emergent surgical repair (ideally within 24 hours) to prevent macular involvement [1][3]
- Macula-off RD: Macula already detached — only 40% achieve ≥20/40 final acuity. Still requires surgical repair, but timing is slightly less emergent (typically within days) [1][13]
Atypical presentations include:
- Asymptomatic RD (some patients have no premonitory flashes/floaters) [7]
- Traumatic RD (may present immediately or be delayed months after injury) [6]
- Exudative RD (no retinal break; underlying inflammatory, vascular, or neoplastic cause) [13][15]
Complications: Proliferative vitreoretinopathy (PVR), recurrent detachment, permanent vision loss, cataract formation post-vitrectomy (>70%) [3]
16. Treatment Plan
Initial stabilization (ED/primary care)
- No effective field or ED treatment exists for RD [5]
- Limit patient activity; avoid Valsalva maneuvers
- Position the patient so the detachment is dependent (e.g., if superior detachment, keep patient upright) to slow progression
- Emergent ophthalmology consultation [1][3]
Definitive surgical management (by retina specialist): [7][16-17]
- Pneumatic retinopexy: Office-based; intravitreal gas bubble + cryotherapy or laser. Best for single superior breaks ≤1 clock hour. ~75% chance of ≥20/50 acuity [17]
- Scleral buckle: Silicone band placed externally to indent the sclera and close the retinal break. Gold standard for simple RRD with good fundus visibility [7][13]
- Pars plana vitrectomy (PPV): Removal of vitreous + gas/silicone oil tamponade. Preferred for complex RRD (giant tears, PVR, vitreous hemorrhage, posterior breaks). Most commonly performed surgery currently. Cataract develops in >70% of phakic eyes post-vitrectomy [3][13][16]
- Laser photocoagulation/cryotherapy alone: For retinal tears without detachment (prophylactic retinopexy) [18]
Surgical success rates: 85%–95% anatomic reattachment with a single procedure [1][13]
17. Disposition
- Emergent ophthalmology referral (same day):
- Confirmed or strongly suspected RD (visual field defect, decreased acuity, fundoscopic or POCUS findings) [1][3-4]
- Macula-on RD — highest urgency to prevent macular involvement [1][3]
- Vitreous hemorrhage or pigmented vitreous cells (Shafer sign) [4]
- Urgent referral (within 24 hours):
- Semi-urgent referral (within 1–2 weeks):
- Admission is generally not required from the ED; most surgical repairs are performed on an outpatient or next-day basis. Admission may be considered for bilateral involvement, complex detachments requiring positioning, or patients unable to follow up reliably.
18. Follow Up / Return Precautions
- Post-PVD without tear: Ophthalmology follow-up within 1–2 weeks; 3.4% incidence of new retinal tear within 6 weeks of uncomplicated PVD diagnosis [4]
- Post-surgical repair: Follow-up per retina specialist (typically within 1 day, then 1 week, then serially)
- Contralateral eye: Regular monitoring — increased risk of RD in the fellow eye [1][12]
Return precautions — counsel patients to seek immediate reassessment for:
- Sudden increase in floaters (especially from <10 to ≥10) [4]
- New or worsening flashing lights
- New or expanding visual field defect (curtain/shadow)
- Any decrease in central vision
- These symptoms should prompt same-day ophthalmologic evaluation [3-4]
Expected recovery: With successful surgical repair, visual recovery depends primarily on macular status at the time of surgery. Macula-on repairs have significantly better visual outcomes than macula-off repairs, underscoring the importance of early diagnosis and prompt referral. [1][13]
