Patient 54 years old, Female, progressive loss of vision. In the multimodal evaluation of the retina showed important retinal alterations. A discreet opacity of the media impairs the quality of the images. In the Autofluorescent Background Image with a green filter, because it reaches a depth in the retinal tissue, it is able to show changes that affect the retinal pigment epithelium, it was better in this case than with the green filter. WF retinography shows an elevated, slightly reddish lesion, probable serous retinal detachment, mobilization of pigments and phantom vessels.

Optic disc pit is a rare anomaly of the optic nerve head that can be associated with maculopathy leading to progressive visual deterioration. It belongs to the spectrum of congenital cavitary anomalies of the optic disc which encompasses extrapapillary cavitation, optic disc coloboma, and morning glory. Very rarely, optic disc pits are seen in combination with optic disc colobomas. Histopathologically, disc pit is defined as herniation of dysplastic retinal tissue into an excavation, rich in collagen, which can stretch into the subarachnoid space via a defect in the lamina cribrosa. Interestingly, this structural abnormality leading to a non-physiological communication between the intraocular and extraocular spaces is a common feature among all the congenital cavitary disc anomalies. Optic disc pit maculopathy is characterized by intraretinal and subretinal fluid at the area of macula. The origin of the retinal fluid remains unclear. Possible sources include the vitreous cavity, the subarachnoid space and the orbital space surrounding the dura. It has been estimated that approximately 25% to 75% of patients will develop serous detachment and/or retinoschisis of the central macula at some stage of their life. On fundus examination, ODPs typically appear as single grayish, round or oval depressions at the optic disc. Most commonly, they are detected at the inferotemporal segment of the disc, but may also be observed elsewhere, including the central area.The coexisting macular detachment can be related to lamellar or full-thickness macular holes, cystoid changes, retinal pigment epithelium atrophy and eventually to irreversible loss of vision,especially in longstanding cases. Herewith, we present a 32-years-old male patient presenting with an unusual combination of optic disc pit with maculopathy and optic disc coloboma (hybrid anomaly) in the same eye with corrected visual acuity of 3/60.

Traumatic retinal dialysis in a 15-year-old male who died 2 weeks follow­ing a motorcycle accident. Upper left shows dialysis of the retina at the ora serrata. Upper right shows hemorrhage In the retina of the fellow eye. Sections through dialysis (lower views) show the detached vitreous base with a small tag of adherent retinal tissue (arrow). (E.P. No. 32955)

Gross and microscopic appearance of a retinal hole. Vitreous tractim has resulted in the hole and detachment of the operculum. Upper right shows the plug of retinal tissue (arrow) attached to the posterior aspect of the detached vitreous. Lower left shows the rounded posterior margin of the retinal hole and the small area of associated retinal detachment. Lower middle and right views are of sections through the detached retinal operculum. (E.P. No. 35238)

Infusion cannula positions can be visualized with the endoscope, especially useful when microscopic views are limited or impossible as in this short movie. Here, the infusion cannula had been placed in a standard fashion but endoscopic imaging reveals partial engagement of peripheral retinal tissue. Manipulation of the tip under endoscopic viewing eliminates the undesired engagement and reveals the proper infusion position with no obstruction.

Condition/keywords: endoscopy, infusion cannula positions, video

This shows the same lesion 11 days following laser photocoagulation. Still more new hemorrhages can now be seen, and the retinal tissue in the center of the lesion is being visibly pulled forward. If you look carefully, you can see the sharp lower edge of a developing tractional horseshoe tear.

This 23-year-old man presented with a fresh retinal detachment in a highly myopic eye and this very unusual retinal appearance. You can see two reddish areas with fairly distinct borders which at first make us think of retinal breaks. However, the left area has two tiny vessels visible in it, and the right area shows visible translucent retinal tissue extending across it. This patient has extensive areas of paving stone degeneration. Usually, such lesions present a barrier to a detaching retina and areas of paving stone usually remain attached. However, in this photograph we can see two paving stone lesions, and the detachment has extended right through them peeling them off from the underlying pigment epithelium. The two reddish areas, therefore, represent the very thin retina which previously constituted part of two paving stone lesions. The yellow atrophic areas which are visible deep to the detached retina represent the deeper parts of the same two original paving stone lesions.
