Peripapillary Pachychoroid Syndrome (PPS):
◾PPS has been recently identified as a distinct Pachychoroid Disease Spectrum variant, in which pachychoroid features surround the optic nerve and are associated with the accumulation of intraretinal cysts and/or subretinal fluid in the nasal macular region rather than the fovea, extending from the temporal margin of the optic disk, as well as with occasional optic nerve head edema in some eyes.
◾Associated clinical findings include peripapillary choroidal thickening, choroidal thickening associated with Haller vessel dilation (pachyvessels) and overlying inner choroidal thinning, serous pigment epithelial detachment and choroidal hyperpermeability, all of which are indicative of a pachychoroid-driven entity.
◾Most of the eyes have hyperopic refraction and short axial lengths. Other common features present in patients with PPS are choroidal folds, older age, and a small cup-to-disc ratio.
◾This entity is seen more commonly in males and is usually bilateral.

The American Academy of Ophthalmology recently updated its clinical guidance on the screening of patients using Plaquenil. Here are the key changes you need to know:

▪ Do baseline SD-OCT + wide-field FAF at initiation (not just dilated fundus exam).
▪ Make OCT + FAF primary; use VF/mfERG to confirm when needed.
▪ Focus on early outer retinal thinning via OCT thickness/change maps; use wider-field imaging, consider 24-2C.
▪ Dose

Type 3 Neovascularization or Retinal Angiomatous Proliferation (RAP):
◾RAP is a neovascularization that starts at the retina and progresses posteriorly into sub retinal space; eventually the neovascularization reaches the choroidal circulation and forms retinal-choroidal anastomoses.
◾This is distinct from CNV in AMD which originates from the choroid and can erode through the RPE and communicate with the retinal circulation through a different mechanism, resulting in a chorioretinal anastomosis.
◾Stages:
Three stages were originally described:
➖Stage I: Intraretinal Neovascularization (IRN):
Vascular proliferation originates from the deep capillary plexus of the retina in the paramacular area and is confined within the retina, as a retinal-retinal anastomosis. Intraretinal haemorrhage and edema are common. Telagiectatic vessels can be seen around the IRN, presumably as a compensatory response to the increased vascular perfusion needed by the IRN.
➖Stage II: Subretinal Neovascularization (SRN):
Neovascularization invades sub retinal space (above/superficial to the RPE). Neurosensory and serous PED can be found, together with increasing edema of the retina and hemorrhages in the pre-retinal and intraretinal spaces.
➖Stage III: Choroidal Neovascularization (CNV):
Choroidal neovascularization (subretinal pigment epithelium) is present. It can be associated with vascularized PED. A retinal-choroidal anastomosis is formed.
◾Clinical diagnosis:
➖The initial lesion is located extrafoveally, presumably because of lack of capillaries in the foveal avascular zone.
➖The presence of small macular hemorrhages, sometimes punctiform, often multiple, associated with edema in an eye with soft drusen, is highly suggestive of RAP in its initial stages.
➖Hemorrhages can be pre, intra or subretinal. Large subretinal hemorrage is rarely seen in stages I and II.
➖As angiogenesis progresses, tortuous, dilated retinal vessels, sometimes showing retino-retinal anastomoses can be found.
➖Involvement is typically bilateral, with 80% of fellow eyes affected after 1 year and 100% before 3 years.
