“…Foveal epiretinal NV following type 2 MacTel on OCTA has been reported by Ayachit et al in 7 eyes of 4 patients. 28 However, none of the cases in their series had PDR In our series, all the five eyes with type 2 MacTel had coexisting PDR with presence of retinal NV within the retinal arcades. It would be difficult to determine if the PDR or type 2 Mactel was responsible for triggering the development of foveal NV in these cases.…”

Purpose Foveal neovascularisation (NV) in proliferative diabetic retinopathy (PDR) is uncommon. The study aim is to analyse a series of cases of foveal NV in PDR and ascertain the factors leading to its development. Methods In this retrospective case-control study, optical coherence tomography (OCT) and OCT-angiography (OCTA) images of PDR cases with/without foveal NV diagnosed on fluorescein angiography were analysed. Results From 124 consecutive PDR eyes, foveal NV was identified in 12 (10%) eyes. Eyes with foveal NV showed thin choroid (p = 0.001), increased FAZ area and reduced vessel density at the macula compared to control group on OCT and OCTA. After regression analysis, an increased FAZ in the superficial capillary plexus slab (p = 0.002) was associated with foveal NV development. Conclusion Our case series suggest that foveal NV is an uncommon finding, occurring due to reduced choroidal and inner retinal perfusion at the macula. Further studies are required to assess the treatment outcomes in such eyes.

“…Recently, Ayachit et al demonstrated an association of epiretinal neovascular membranes with the help of OCT angiography in seven eyes out of 68 patients known to have MacTel. OCT angiography showed a unique vascular proliferation at the level of vitreoretinal interface distinct from the pathognomonic dilated and ectatic capillaries in the superficial and deep vascular plexus that is typical of MacTel [ 8 ]. Our patient, unfortunately, had an OCT angiography taken only after the vitrectomy; therefore, this finding could not be observed.…”

We report a case of a 62-year-old man who presented with blurred and distorted vision in both eyes. Fundus examination revealed a fibrous band-like membrane emanating from the disc to the foveal center in the right eye, aneurysmal gray parafoveal lesions in both eyes, and an inferotemporal peripheral vascular tumor in the right eye. The presence of an epiretinal membrane with vitreomacular traction in this patient has led to the diagnosis of an incidental peripheral vascular tumor. To our knowledge, there are no reports describing an association between macular telangiectasia type 2 and epiretinal membrane formation with vitreomacular traction due to a vasoproliferative tumor.

“…K. Rajurkar and his colleagues reviewed the OCTA features of central Eales disease in case series, they noticed a common nding of deep capillary plexus changes but they did not have a patient in their series with macular ERN in which the origin and morphology of these tiny macular neovessels were shown [6]. ERN was described in cases of diabetic retinopathy, retinal venous occlusion, and recently in cases of macular telangiectasia type 2 and retinitis pigmentosa [7], [8], [9]. In diabetic retinopathy, the neovascularizations was classi ed by OCTA based on morphology and relationships of retinal neovascular complexes and the posterior vitreous into three types: at, forward con guration into the vitreous, similar to the con guration in our patient, and tabletop [10].…”

Background: Eales disease primarily affects the peripheral retina. However, posterior involvement can be seen. Macular epiretinal neovascularization is not commonly seen in Eales disease. This report highlights the morphology and origin of macular epiretinal neovascularization (ERN) using multimodal retinal imaging, including optical coherence tomography angiography (OCTA). Results: A 35-year-old man with no history of systemic disorders presented with gradual decrease of vision in his left eye. Fundus examination of his right eye showed peripheral sclerosed blood vessels, neovascularization of the optic disc and elsewhere, and macular ERN. The view of the left fundus was limited by vitreous haemorrhage. Fluorescein angiography (FA), of the right eye showed widespread peripheral capillary nonperfusion and leakage of dye from the retinal neovascularization and macular ERN. Macular Spectral domain optical coherence tomography (SD-OCT) of the right eye showed an epiretinal membrane and the presence of epiretinal neovascular lesions extending above the internal limiting membrane towards the vitreous. Optical coherence tomography angiography (OCTA) showed multiple tiny blood vessels at the macula that arose from the superficial retinal capillary plexuses and extended toward the vitreous. The corresponding B-scan showed flow signal through these vessels and the signal extend above the internal limiting membrane. Systemic work-up was negative except for strongly positive tuberculin skin testing giving the classic diagnosis of Eales disease. Patient was started on empirical anti-tubercular therapy and oral corticosteroids. Scatter laser photocoagulation was applied to nonperfused retinal zones. Despite adequate scatter laser ablation, the ERN failed to regress fully. Conclusions: Macular ERN can be seen in cases of classic Eales disease. The origin of macular ERN in our case was shown to be from the superficial retinal capillary plexuses. We also noted the slower regression rate of macular ERN as compared to the major neovascularizations of the optic disc and peripheral retina. Further research is needed to establish the pathogenesis of ERN and its optimal management.
