After six years, the previous lesion looked like this. The former flap has been completely avulsed and is now a free operculum. The white zone around the tear represents the small area of detachment and subretinal fluid. It is still asymptomatic and does not require treatment.

Condition/keywords: does not require treatment, free operculum, operculated retinal hole, subretinal fluid, white retinal tuft

This is the fellow eye of the previous patient showing three tiny delicate tufts with parts of the tufts avulsed by vitreous traction. These lesions are symmetrically located in the fellow eye as compared to the lesion in the previous two slides.

Condition/keywords: symmetrical, vitreous traction, white retinal tuft

This white retinal tuft was seen in a 20-year-old man. It is associated with an asymptomatic retinal tear posterior to the tuft and with a tiny adjacent amount of subretinal fluid. It remained just like this for six years and then underwent the change shown in the next slide pair.

Condition/keywords: asymptomatic, subretinal fluid, white retinal tuft

This 60-year-old man suddenly developed a vitreous hemorrhage from this acute horseshoe tear 3½ years following cataract extraction when a posterior vitreous detachment occurred. The white nubbin identifies this lesion as a preexisting cystic retinal tuft. The pigment spot beneath the flap is evidence of secondary trophic changes in the pigment epithelium. Note the irregular shape of the flap with the narrow tip and broad base. This was caused by vitreous traction which was exerted at two separate points on the retina and which tore the retina at each place.

Condition/keywords: acute posterior vitreous detachment, irregularly shaped flap, trophic pigmented changes, vitreous hemorrhage, vitreous traction, white retinal tuft

This 60-year-old man suffered a sudden posterior vitreous detachment which produced a large tractional retinal tear at 11:30 o’clock in this eye. This white cystic retinal tuft located at 9:30 also suffered minor injury at the same time as revealed in the next slide pair.

Condition/keywords: posterior vitreous detachment, white retinal tuft

This 68-year-old woman had a recent posterior vitreous detachment which produced this symptomatic horseshoe tear exactly at the site of this cystic retinal tuft. Note the characteristic discrete white nubbin at the apex, which is produced by a cap of glial cells with densely packed cytoplasm.

Condition/keywords: cystic retinal tuft, glial cells, posterior vitreous detachment, white retinal tuft

This lattice lesion in a 44-year-old woman shows an interesting tuft arising from the edge of the lesion and seen well against the background of the shadow of the indentation. It is caused by glial proliferation into the vitreous condensation at the edge of the lesion. Around the borders of each lattice lesion there is an invariable attachment of condensed vitreous. It is this vitreoretinal attachment that comprises the chief danger of lattice lesions where it may lead to acute retinal tears and retinal detachment at the time of posterior vitreous detachment.

Condition/keywords: glial proliferation, lattice degeneration, scleral indentation, vitreoretinal attachment, vitreous condensation, white retinal tuft
