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

This shows the appearance of scleral indentation in a normal eye. Note the convex shadow which marks the posterior border of the indented area. It is caused in part by a small angle which separates the viewing axis from the illuminating axis thus allowing the observer to see slightly into the shadow beyond the illuminated crest of the indentation. It is also caused in part by viewing the pigment epithelial layer in a tangential manner. This shadow is of great diagnostic usefulness since it becomes a dark background against which many tiny retinal abnormalities can be seen beautifully by contrast. Two other particular advantages of scleral indentation will be demonstrated in the following photographs: First, the ability to see the extreme anterior part of the retina to the ora serrata and beyond, and second, the ability to examine any abnormality in multiple profiles depending on slight movements of the scleral depressor in various directions.

Condition/keywords: extreme anterior retina, posterior border, scleral indentation, shadow, tangential view of pigment epithelial layer

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 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

This is the same case as the previous photograph. With scleral indentation slightly more posterior, the flap is seen to be associated with a large retinal tear. This is a tractional tear and it is possible that in this case the cryotherapy itself may have increased the vitreoretinal traction at this site and in this way led to this new tear. The age of the tear is unknown because it was asymptomatic, and even though the eye is aphakic the tear has not caused a clinical retinal detachment.

Condition/keywords: retinal flap, scleral indentation, tractional retinal tear, vitreoretinal traction

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

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

This horseshoe tear was the cause of the detachment in this 54-year-old man. The orange area on the right half of the slide represents the area of scleral indentation. Please note that most of the tear lies over the indented area and appears orange. However, the extreme left side of the tear is brownish black in color because it is exactly superimposed over the dark shadow that always lies just beyond the indented area. The ability of scleral indentation to produce this color change combined with a sharp demarcation between the blackish area and the yellowish edge of intact retina is a pathognomonic sign of a full thickness retinal break.

Condition/keywords: scleral indentation

This is the same case as seen in the previous photograph but is a different view with the scleral indentation moved more anterior. The retinoschisis is seen to be very peripheral coming at least grossly right up to the ora serrata. Please notice how clear a view one can get of the ora serrata and pars plana using indirect ophthalmoscopy with scleral indentation.

Condition/keywords: ora serrata, retinoschisis, scleral indentation

This 75-year-old woman had a scleral buckling operation on this aphakic eye two months previously. Two months following surgery she again had new symptoms of blurred vision and was found to have a redetachment caused by this small tractional retinal tear which may have been missed at the time of her original operation.

Condition/keywords: aphakic eye, scleral buckle, tractional retinal tear
