30-year-old female patient diagnosed with Syndrome VHL (Von Hippel Lindau). Stage II. In the first wide-field retinography of the right eye we can observe the exophytic retinal hemangiomas, rounded, slightly delimited, located in the peripheral retina in the upper and lower temporal quadrants and due to the exudation produced by them, hard exudates are observed in the star hemisphere, affecting the macula.

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.

We present a case of a 33-year-old male patient, who presented with decreased visual acuity in his right eye with 20/80, presenting a primary retinal vasoproliferative tumor in the lower temporal quadrant. The fluorescein angiography findings are: 1. Early hyperfluorescence due to its rich intrinsic vascularity and often has dilated feeding arterioles and draining venules. 2. Marked progressive leakage from the tumor vessels. 3. The late leakage often obscures fine vascular details in the late phase and corresponds to exudation and macular edema seen clinically. 4. Staining of surrounding exudates, RPE disturbances and gliosis. 5. In our case also a marked peripheral capillary closure in the areas adjacent to the tumor and in other quadrants as well.

We present a case of a 33-year-old male patient, who presented with decreased visual acuity in his right eye with 20/80, presenting a primary retinal vasoproliferative tumor in the lower temporal quadrant. The tumor is associated with serous retinal detachment, hard exudation, neovascularization and telangiectasias. Lipid exudates extend toward the macula, indicating macular involvement, which may contribute to decreased visual acuity. Oi was normal with 20/20 of BCVA. The patient was treated initially with IV anti-VEGF therapy and cryotherapy.

This 48-year-old woman has senile retinoschisis involving the most common location, the lower temporal quadrant. The lesion shown here illustrates one of the two clinical features which are most often responsible for attracting the attention of the examiner to such lesions, namely the multitude of yellow flecks lying on the inner surface of the inner layer. The nature of these flecks is not known, but it seems clear that they do not originate in the schisis cavity for they do not represent remnants of ruptured Miller’s fibers. In this photograph you can easily detect the fluid space which separates the inner and outer retinal layers.
