This is the same case as seen in the previous photograph but showing an area just below the lower end of the dialysis. It shows a congenital meridional fold at the 2 o’clock meridian with a retinal break at the posterior end possibly caused by the direct injury described previously.

Condition/keywords: meridional fold, ora serrata, retinal break

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 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 the normal nasal ora serrata showing a prominent meridional fold. Such folds are most commonly seen at the lower part of the upper nasal quadrant, and are present in 26% of the population. They are a normal developmental variation and are often bilateral.

Condition/keywords: meridional fold, normal developmental variation, normal nasal ora serrata, upper nasal quadrant
