Rubella retinopathy is usually a benign disorder with low impact on visual acuity. However, choroidal neovascularization can occur in these patients threatening their vision. We report the case of a 6-year-old girl with rubella retinopathy who developed a neovascular membrane and was successfully managed with observation. Decision to treat or observe in these patients must be carefully weighed, with both options being valid depending mainly on the location of the neovascular complex.

Normal development of the fovea begins before midgestation and continues for several years after birth. Foveal hypoplasia is a condition in which the foveal pit and the foveal avascular zone do not fully develop. Several diseases are known to be associated with foveal hypoplasia; however, a direct association between foveal hypoplasia and congenital rubella has not been stated so far. This report describes a case of foveal hypoplasia detected during adulthood in a patient with known fetal exposure to maternal rubella infection and several ocular features of congenital rubella syndrome, including microphthalmia, congenital cataract, and pigmentary retinopathy. During follow-up, the visual acuity and ocular fundus changes remained stable.

OBJECTIVE: Many retinal disorders present with pigmentary retinopathy, most of which are progressive conditions. Here we present over nine years of follow up on a case of stable pigmentary retinopathy that is suspected to stem from a congenital rubella infection. Parafoveal cone photoreceptors were tracked through this period to gain insight into photoreceptor disruption in this pigmentary retinopathy.
METHODS: The patient was examined at 8 visits spanning a total of 111 months. Examination at baseline included clinical fundus examination, full-field electroretinography (ERG), kinetic visual field assessment (Goldmann), and best corrected visual acuity; all of these except ERG were repeated at follow up visits. Imaging was performed with fundus photography, spectral-domain optical coherence tomography (SD-OCT) and confocal adaptive optics scanning light ophthalmoscopy (AOSLO). For the latter four time points AOSLO imaging also included split-detector imaging.
RESULTS: There were no defects in hearing or cardiac health found in this patient. There were minimal visual deficits found at baseline, with mild rod suppression on ERG; best corrected visual acuity was 20/25 OD and 20/20 OS at baseline, which was stable throughout the follow-up period. Retinal thickness as measured by OCT was within the normal range, though foveal hypoplasia was present and outer nuclear layer thickness was slightly below the normal range at all time points. Cone density was relatively stable throughout the follow-up period. A number of cones were non-reflective when observed with confocal AOSLO imaging and density was markedly lower than expected values (foveal cone density was 43,782 cones/mm2 on average). Genetic analysis revealed no causative variations explaining the phenotype.
CONCLUSIONS: This patient appears to have a stable pigmentary retinopathy. This case is likely due to a congenital insult, rather than progressive retinal disease. This finding of stability agrees with other reports of rubella pigmentary retinopathy. Imaging with AOSLO enabled observation of two notable phenotypic features. First is the observation of dark cones, which are seen in many retinal disorders including color vision defects and degenerative retinal disease. Second, the cone density is well below what is expected - this is especially interesting as this patient has near-normal visual acuity despite this greatly decreased number of normally-waveguiding cones in the fovea.

BACKGROUND: Rubella is an important infectious, vaccine-preventable etiology of congenital defects. The aim of the study was to develop a prediction nomogram to assess the probability of an infant being at risk for congenital rubella based on demographics and ophthalmological findings.
METHODS: This was a cross-sectional sentinel surveillance study conducted at 5 centers spanning pan-India and involved 1134 infants. The diagnosis of rubella was made using standard guidelines. For the construction of the prediction model, laboratory-confirmed cases were grouped as \"at-risk\" (AR) infants and the discarded cases into \"not at risk\" (NAR) infants. Univariate analysis (p value cut-off < 0.05) followed by multivariate binary logistic regression model development was performed.
RESULTS: The average (median) age of the suspected CRS infants was 3 (IQR 1-6) months, and the average (mean) age of their mothers was 25.8 ± 4.1 years. Out of the total infants, 81 (7.3%) died, 975 (88%) were alive, and 55 (5.0%) were lost to follow-up. The final model showed that the odds of cataract, retinopathy, glaucoma, microcornea, and age of the infant at presentation were 3.1 (2.2-4.3), 4.9(2.3-10.4), 2.7(1.1-5.9), 2.3(1.1-4.7), and 1.1 (1-1.1), respectively, for the AR infant as compared to NAR infant. AUC of final model was 0.68 (95% CI Delong, 0.64-0.72). Bootstrapping for calibration of the model showed satisfactory results. Nomogram, along with a web version, was developed.
CONCLUSIONS: The developed nomogram would have a wide community-based utilization and will help in prioritizing attention to high-risk children, thereby avoiding loss to follow-up.

BACKGROUND: A phenocopy is an individual showing features (phenotype) characteristic of a genotype but produced environmentally rather than genetically (not inherited); these features are not due to mutations, as the underlying DNA sequence of the phenocopy is not altered.

OBJECTIVE: To report a case of choroidal neovascularization (CNV) associated with rubella retinopathy (RR) treated with intravitreal aflibercept.
METHODS: A 15-year-old girl presented a complaint of visual decrease in her left eye. She had a history of hearing decrease since she was 1 year old in addition to patent ductus arteriosus. On ocular examination, the best corrected visual acuity (BCVA) was 20/20 in the right eye and 20/400 in the left eye. Dilated fundus examinations revealed a classic salt-and-pepper appearance in both eyes and a whitish subretinal lesion with retinal hemorrhages in the left macula. Fundus fluorescein angiography (FFA) of the left eye illustrated a pattern of diffuse spotty fluorescence with an active subfoveal CNV lesion, that hyperfluoresces in the early phases of the FFA, maintains well-demarcated borders, and leaks. Spectral domain optical coherence tomography (SD-OCT) revealed thickened and elevated retinal layers at the macula due to the subretinal and intraretinal fluid with foveal and extrafoveal protruding hyper-reflective lesion in the left eye. Single dose of intravitreal aflibercept was performed to the left eye and at the first month after the injection, the BCVA improved to 20/100 and the OCT revealed scar formation. At the follow-up visits, the macula was similar to those at the first month post-injection, and the BCVA was preserved. No additional injections were needed.
CONCLUSIONS: Intravitreal aflibercept may be a treatment alternative, which provides satisfactory anatomical and functional results and leads to a better visual acuity in cases with RR complicated by CNV.
