This is the same lesion as in the previous slide pair but the photograph was taken nine years later when the patient was 58-years-old soon after an acute posterior vitreous detachment. This demonstrates that posterior vitreous detachment can produce large retinal tears at these sites. However, it is important to emphasize that prophylactic treatment of cystic retinal tufts in the absence of a retinal tear would be very ill-advised because several hundred innocence and harmless lesions would have to be treated in order to prevent one tear of the retina.

Condition/keywords: cystic retinal tuft, posterior vitreous detachment, retinal tear

This is the normal temporal ora serrata in a 26-year-old man. Note the typical ragged moth-eaten appearance caused by peripheral cystoid degeneration. This appearance may be present in infants but is always present beyond the age of eight years.

Condition/keywords: ora serrata, peripheral cystoid degeneration

This is the same lesion as in the previous photograph. With the scleral indentation placed more posterior, we now can see that the fold ends over a small collection of subretinal fluid and that there is a very tiny retinal hole just below the posterior end of the retinal fold.

Condition/keywords: peripheral cystoid degeneration, retinal fold, retinal hole, scleral indentation, subretinal fluid

This is a cyst of the pars plana located just anterior to the ora serrata in the lower temporal quadrant. It illustrates how far anterior one may visualize the fundus with indirect ophthalmoscopy and scleral indentation. Pars plana cysts are common lesions of no particular clinical significance.

Condition/keywords: cyst of the pars plana, lower temporal quadrant, ora serrata, scleral indentation

The next two photographs are of the same lesion in a 28-year-old woman. This view shows a sloping retinal mound with a radial retinal fold in the center. This is not a typical meridional fold for it stops short of the ora serrata and there is no dentate process. The upper temporal ora serrata and pars plana are well shown and peripheral cystoid degeneration is present posterior to the ora.

Condition/keywords: ora serrata, pars plana, peripheral cystoid degeneration, radial retinal fold, sloping retinal mound

This is a rather poor photograph taken in 1969 but is important for comparison with the next slide pair. It shows a cystic retinal tuft in a 49-year-old woman and was taken without scleral indentation. The two pigment spots just inferior to the tuft represent a secondary degenerative change in the pigment epithelium.

Condition/keywords: cystic retinal tuft, degenerative changes of retinal pigment epithelium, pigmented spots

This small elevated peripheral retinal lesion in a 48-year-old woman is a cystic retinal tuft. Such tufts are congenital developmental anomalies present from birth and situated behind the vitreous base. They are sites of abnormal vitreoretinal attachment, and can occasionally lead to retinal tears at the time of posterior vitreous detachment. They are present in about 5% of patients.

Condition/keywords: abnormal vitreal retinal attachment, behind the vitreous base, congenital anomaly, cystic retinal tuft, developmental anomaly, peripheral retinal lesion, present from birth

This is the appearance of the previous lesion three weeks following prophylactic cryotherapy. Continuing vitreal retinal traction has a now torn the flap completely free from the retina. The whitish cystic retinal tuft can be discerned on the upper part of the free operculum. Along the lower half of the operculum superimposed over the dark shadow of the scleral indentation one may observe numerous, delicate, vitreous fibrils actually attaching to the operculum.

Condition/keywords: cystic retinal tuft, free operculum, prophylactic cyrotherapy, retinal flap, scleral indentation, vitreoretinal traction, vitreous fibrils

Chronic retinal detachments can be associated with demarcation lines (tidemarks), subretinal bands or sheets, and retinal cysts. Fundus photo of a chronic inferior retinal detachment reveals multiple demarcation lines inferior to the center of the fovea as a result of an inferior temporal dialysis.

Fundus autofluorescence of retinitis pigmentosa showing hyperautofluorescent rings or foveal hyperautofluorescence.

This asymptomatic lesion in a 27-year-old woman is a very interesting example of a cystic retinal tuft. Note the discrete white nubbin, which is the chief characteristic of this lesion. In this case, it is surrounded by a small area of subretinal fluid. The next slide pair will reveal the reason for this.

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

This is the same lesion seen in the previous slide pair. With the scleral indentation performed more posteriorly, a small hemorrhage can be seen on the white tuft. This is proof of the vitreal retinal attachment at this spot. Posterior vitreous detachment can produce a retinal tear at the site of a cystic retinal tuft, but in this case has caused only a small hemorrhage.

Condition/keywords: posterior vitreous detachment, retinal hemorrhage, scleral indentation, vitreoretinal attachment

Patient with a history of wet macular degeneration and glaucoma in both eyes. VA is 20/50, right eye, 20/80, left eye. Patient is treated with Eylea in both eyes. Enhanced depth imaging OCT reveals a small like form of a cyst which in fact isn't a cyst at all. This is called outer retinal tubulation in which degenerating photo-receptors may become arranged in a circular or ovoid fashion. This is sometimes misdiagnosed as cystic changes in the retinal pigment epithelium or sub-retinal fluid.

This is another example of a symptomatic retinal tear which occurred at the site of a cystic retinal tuft two days prior to the photograph when an acute posterior vitreous detachment occurred in this 64-year-old woman. Note the horizontal line of vitreous blood along the lower edge of the flap which demarcates the vitreous attachment to the flap.

Condition/keywords: acute posterior vitreous detachment, cystic retinal tuft, retinal flap, retinal tear, vitreous blood

This is a fresh, symptomatic horseshoe tear at the site of a cystic retinal tuft in a 63-year-old man. This is really a double horseshoe tear because the two retinal vessels have resisted the vitreal retinal traction and have preserved an intact bridge of tissue between the tears. Note the prominent vitreous condensation attached to the apex of the upper tear and made much more visible because it is seen superimposed over the dark underlying shadow of scleral indentation.

Condition/keywords: bridge of tissue between tears, cystic retinal tuft, scleral indentation, vitreous condensation

Chronic retinal detachments can be associated with demarcation lines (tidemarks), subretinal bands or sheets, and retinal cysts. Fundus photo of a chronic retinal detachment reveals a branching subretinal band superior nasal to the macula with a portion extending to the inferior margin of the optic disc.
