Red spots and streaks in the fundi (on fundoscopic exam) usually indicate retinal or
vascular pathology. Here are the key causes:
🔴 Red Spots
● Retinal hemorrhages
○ Flame-shaped hemorrhages: in the nerve fiber layer, seen in hypertension,
retinal vein occlusion.
○ Dot/blot hemorrhages: in the deeper retinal layers, common in diabetic
retinopathy.
● Microaneurysms: small, round red dots, earliest sign of diabetic retinopathy.
🔴 Red Streaks
● Flame hemorrhages along the nerve fiber layer → look like streaks (HTN,
papilledema, blood dyscrasias).
● Subhyaloid hemorrhage: streaking under the vitreous.
● Roth spots: round hemorrhages with white/pale centers (seen in infective
endocarditis, leukemia, diabetes).
✅RedClinical Meaning:
spots and streaks in the fundi most commonly point to hypertensive retinopathy or
diabetic retinopathy, but may also reflect systemic disease like endocarditis or leukemia.
🔎 Types of Retinal Findings
1. Superficial Retinal Hemorrhages (Flame-shaped)
○ Appearance: Flame- or feather-like streaks following the nerve fiber layer.
○ Common Causes: Hypertension, retinal vein occlusion, papilledema, blood
dyscrasias (anemia, thrombocytopenia).
2. Preretinal Hemorrhage
○ Appearance: Boat-shaped or D-shaped hemorrhage between the retina and
vitreous. Often pools due to gravity.
○ Common Causes: Trauma, Valsalva retinopathy (coughing, straining),
proliferative diabetic retinopathy, retinal tears.
3. Deep Retinal Hemorrhages (Dot/Blot hemorrhages)
○ Appearance: Small, round or blot-like hemorrhages in the deeper retinal layers.
○ Common Causes: Diabetic retinopathy, retinal vein occlusion, hypertension.
4. Microaneurysms
○ Appearance: Tiny, round, red dots; earliest ophthalmoscopic sign of diabetic
retinopathy.
○ Common Causes: Diabetes mellitus (damage to retinal capillary walls).
✅ Clinical Pearl:
● Superficial = flame (hypertension, vein occlusion).
, ● Deep = dots/blots (diabetes).
● Preretinal = boat-shaped (trauma, proliferative changes).
● Microaneurysms = diabetes early warning.
The hallmark of acute otitis media (AOM) is:
👉 Bulging of the tympanic membrane with middle ear effusion
Key Features of AOM:
, ● Bulging, erythematous tympanic membrane
● Decreased mobility of the tympanic membrane on pneumatic otoscopy
● Presence of middle ear effusion (air-fluid level or opacity)
● Symptoms: ear pain (otalgia), fever, irritability, conductive hearing loss
📌 According to the American Academy of Pediatrics (AAP), the most specific diagnostic
criterion is a moderate to severe bulging of the tympanic membrane (Lieberthal et al.,
2013; updated clinical guidelines).
Distorted Tympanic Membrane (TM) Landmarks
Normally, the tympanic membrane is translucent, pearly gray, and key landmarks (light reflex,
handle of malleus, umbo, and cone of light) are clearly visible.
When there is pathology (like acute otitis media, otitis media with effusion, or perforation),
these landmarks may appear distorted or absent due to changes in the TM and middle ear.
Causes of Distorted Landmarks
1. Bulging TM (e.g., Acute Otitis Media)
○ Landmarks obscured or displaced
○ Cone of light disappears
○ Handle of malleus difficult to see
2. Retracted TM (e.g., Eustachian Tube Dysfunction, OME)
○ Landmarks appear unusually prominent and foreshortened
○ Cone of light is distorted or shifted
○ Malleus appears pulled inward
3. Thickened or Opaque TM
○ Loss of translucency → landmarks difficult to visualize
4. Perforation or Scarring (Tympanosclerosis)
○ Landmarks disrupted, irregular white plaques may obscure them
Clinical Significance
● Distorted landmarks = sign of pressure or fluid behind the TM.
● Helps differentiate acute otitis media (bulging, loss of cone of light) from OME
(retraction, visible malleus).
● Important in guiding treatment (antibiotics vs watchful waiting).

and opaque.
