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 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

This is a more typical classical example of lattice degeneration in a 42-year-old woman in a photograph taken without scleral indentation. It shows much more marked vascular changes than the previous case. Note the tapering of the blood columns as the vessels approach the lesion and also the white sheathing of the vessel walls. Note also the continuity of the blood vessels on opposite sides of the lesion with the characteristic white lattice lines. More than 45 years ago Vogt pointed this out as a proof that these white lines were actually caused by changed blood vessels. Note also that this lesion shows a combination of several individual features of lattice degeneration. In addition to the white lines, there is a reddish crater-like area beneath the main horizontal white line. There is a prominent horizontal zone below this white line showing a snailtrack appearance. Also, there are two tiny atrophic retinal holes outside the photograph on the right end of this lesion. This eye contained five such retinal holes and they have all remained unchanged for more than 10 years of observation without treatment.

Condition/keywords: atrophic retinal hole, lattice degeneration, moderate snail track, tapering blood columns, white lattice lines, white sheath vessel

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

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 photograph shows a rather typical example of the white with pressure phenomenon. It may take many forms but usually has a geographic configuration with irregular borders which may be rounded or angular. Its cause is unknown but it is a very common finding in the fundus. It is important to know that it does not indicate the presence of any disease of the retina. Over a period of time, it may disappear completely or it may change its configuration or location. Other examples of this phenomenon are shown in slide pairs 81 and 103.

Condition/keywords: geographic configuration, irregular borders, white retinal lesion, white with pressure

This 16-year-old girl has lattice degeneration and also this large oval retinal hole with a surrounding narrow zone of subretinal fluid. This lesion illustrates how large the atrophic holes of lattice degeneration may be. Occasionally the hole can be as large as the initial lattice lesion and can therefore obliterate all other evidence of its true identity. This was almost true in this case, but there does remain a small whitish remnant of the original lattice lesion at the lower end of the oval hole.

Condition/keywords: lattice degeneration, retinal hole, subretinal fluid, white lattice lines

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 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

In this 26-year-old woman, these two atrophic holes in a lattice lesion led to a clinical retinal detachment which was operated on successfully. In retinal detachments of this type resulting from non tractional atrophic holes, it has been found that 50% occur before the age of 30 years.

Condition/keywords: atrophic retinal hole, lattice lesion

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.

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
