Retina Conditions

Retinal pathology can be visually devastating yet often asymptomatic in early stages, making structured screening essential. This section consolidates common vascular, macular, inherited, and pediatric retinal conditions with clinically practical summaries. Prioritize urgent referral for acute vision loss, new flashes/floaters with field defects, and ischemic retinal events.

Last updated: March 2026

Retina-focused care in optometry relies on timely imaging, risk stratification, and clear thresholds for escalation. Diabetes, hypertension, aging, high myopia, and systemic vascular disease remain dominant risk factors across many entities. Distinguishing stable chronic changes from acute threats enables safer co-management and better long-term outcomes. Monitor for neovascular complications, macular edema, and tractional progression in all high-risk cohorts.

Retina disease index (A–Z)

Age-Related Macular Degeneration

Leading cause of central vision loss in older adults with dry atrophic and wet neovascular subtypes requiring different follow-up intensity.

Branch Retinal Artery Occlusion

Acute sectoral ischemic event often embolic; requires urgent systemic vascular risk evaluation and retinal assessment.

Branch Retinal Vein Occlusion

Localized venous occlusion with hemorrhage and edema; monitor for macular edema and neovascular sequelae.

Central Retinal Artery Occlusion

Ophthalmic stroke causing sudden profound vision loss; emergency referral and stroke pathway activation are critical.

Central Retinal Vein Occlusion

Diffuse venous congestion with extensive hemorrhage and ischemia; high risk of neovascular glaucoma in severe cases.

Central Serous Retinopathy

Serous neurosensory detachment linked to stress and corticosteroids, often self-limiting but recurrent in some patients.

Coats Disease

Idiopathic retinal telangiectasia with exudation, often unilateral in younger patients and potentially vision-threatening.

Cystoid Macular Edema

Intraretinal cystic fluid accumulation after surgery, inflammation, or vascular disease causing central visual distortion.

Diabetic Retinopathy

Progressive microvascular damage from diabetes; regular screening reduces risk of preventable vision loss.

Epiretinal Membrane

Macular surface fibrosis causing metamorphopsia and reduced acuity, with surgery considered in symptomatic progression.

Hypertensive Retinopathy

Retinal vascular changes from chronic or severe hypertension; fundus signs can mirror systemic cardiovascular risk.

Macular Hole

Full-thickness foveal defect causing central blur and distortion, often requiring vitreoretinal surgical evaluation.

Retinal Detachment

Neurosensory retina separation presenting with flashes, floaters, and curtain-like field loss; urgent repair is time-sensitive.

Retinal Tear

Peripheral full-thickness retinal break that can progress to detachment; laser barricade is often preventative.

Retinitis Pigmentosa

Inherited rod-cone degeneration with nyctalopia and constricted fields, requiring long-term multidisciplinary care.

Retinoblastoma

Childhood intraocular malignancy often presenting with leukocoria; urgent oncology-ophthalmology referral is essential.

Retinopathy of Prematurity

Abnormal retinal vascular maturation in premature infants, requiring strict screening windows and follow-up.

Sickle-Cell Retinopathy

Peripheral ischemia with sea-fan neovascularization in hemoglobinopathies; recurrent hemorrhage risk requires surveillance.

Vitreous Hemorrhage

Bleeding into vitreous cavity from neovascularization, tears, or trauma causing sudden floaters and reduced vision.
