Retinal Dialysis
Jul 5 2025 by Gustavo Uriel Fonseca Aguirre
This B-mode longitudinal ultrasound scan demonstrates a retinal dialysis, appearing as a linear discontinuity at the ora serrata with associated vitreous base avulsion. The scan reveals mild subretinal fluid extending from the dialysis site with macular involvement.

Retinal Detachment Secondary to Anomalous PVD
Mar 13 2025 by Fabricio Dolores
This color wide-field clinical image depicts the right eye of a female patient who experienced a sudden loss of vision one month earlier. She was initially diagnosed with a vitreous hemorrhage and managed with conservative treatment. Upon presentation to our institute one month later, a superior rhegmatogenous retinal detachment was identified, extending across the 12 o’clock meridian. This was accompanied by an inferior vitreous hemorrhage and a solitary superior retinal lesion located at M11 in the superior triangle of the ora serrata, in alignment with Lincoff's second law.

A Classic Case of Retinal Ora Serrata Imaging
Jan 16 2025 by yuan duo
A 5-year-old girl, born full-term with no history of systemic disease, presented with poor vision since early childhood and underwent fundus examination. Anterior segments of both eyes showed no significant abnormalities. Fundus examination revealed retinal folds extending from the optic disc to the temporal peripheral retina, with blood vessels coursing through the folds (A, B). Avascular zones were observed in the peripheral retina, and the ora serrata’s boundaries were clearly visible, displaying dentate processes and bays (C, D). Retinal pigmentation was evident. Genetic testing confirmed the final diagnosis of bilateral Familial Exudative Vitreoretinopathy (FEVR).

Human Vitreous Base Structure
Sep 1 2020 by J. Sebag, MD, FACS, FRCOphth, FARVO
Dark-field slit microscopy was performed on fresh, unfixed, post-mortem human eyes that had undergone dissection to peel off the sclera, choroid, and retina. The vitreous body remains attached to the anterior segment which is seen below, while the posterior pole is above in these images. Left: specimen was tilted to reveal the posterior aspect of the lens (L) and the fibers of the vitreous base (arrow) splayed out to insert anterior and posterior to the ora serrata; Right: Anterior Loop of the vitreous base (see text).

Pars Plana Cysts
Jan 29 2018 by Shani Pillar
During a pars plana vitrectomy for fixation of a dislocated IOL, this finding of pars plana cysts was seen, while performing indentation. Pars plana cysts are not uncommon, but rarely visualized so clearly, given their extremely peripheral location.

PVD With Vitreous Attachment to Retinal Tear
Dec 10 2012 by Yale L. Fisher, MD
There is a posterior vitreous face separation with remaining attachment to a retinal flap tear. Movement of the tear is visible during voluntary motion of the patient's eye. There is strong reflectivity from the flap tear (yellow arrow) and moderate reflectivity from the vitreous face (green arrow). The peripheral retinal tear is seen in this sagittal nasal cut near the medial rectus muscle insertion, which localizes the tear to the ora serrata around the 3 o'clock position.

Cyst of the Pars Plana
Nov 9 2012 by Norman Byer
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.

Meridional Fold
Nov 9 2012 by Norman Byer
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.

Yellow Globular Lesion
Nov 9 2012 by Norman Byer
This glistening yellow globular lesion is a so-called pearl of the ora serrata in a 45-year-old man. Notice location in the tooth of the ora, which is a characteristic of this lesion. Histologically pearls are drusen-like structures which form on the inner side of Bruch’s membrane beneath the pigment epithelium. They are seen in about 20% of eyes and are often bilaterally symmetrical. They have no clinical significance but are valuable as landmarks.

Senile Retinoschisis
Nov 9 2012 by Norman Byer
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.
