Background To report retinal pigment epithelium (RPE) apertures as a possible evolution of serous pigment epithelium detachment (PED) in patients with chronic central serous chorioretinopathy (CSC) and to analyze their progression over time. Design Retrospective case series. Methods Fifteen patients (17 eyes) with a diagnosis of avascular PED in chronic CSC were retrospectively evaluated based on multimodal imaging. All patients had documented records of clinical examination, best correct visual acuity (BCVA), fundus autofluorescence (FAF), fluorescein and indocyanine green angiography, spectral-domain optical coherence tomography, and optical coherence tomography angiography (OCT-A). Primary outcomes measures were RPE aperture imaging analysis along with their temporal course. Results All eyes showed the RPE aperture as an interruption of the RPE in correspondence of the PED with neither sign of rippling nor retraction. Mean age was 59.4 ± 8.1 years and mean BCVA was 0.34 ± 0.24 logMAR. In all eyes, FAF displayed a well-circumscribed roundish hypoautofluorescence. Multimodal imaging and OCT-A confirmed the absence of any vascular network beneath the aperture in all study eyes. The mean time of follow-up was 19.3 ± 14.3 months, and RPE discontinuities showed an increase in size over time from 0.81 ± 0.39 mm 2 to 0.95 ± 0.45 (P = 0.005). Conclusions RPE aperture is a new finding in the setting of chronic CSC and it should be distinguished by RPE tears for the different pathogenesis and evolution in time.
Anterior uveitis with or without keratitis was the most common presentation observed in more than 50% cases. The overall visual outcome was good.
A 68-year-old man presented with diminution of distance and near vision in the right eye for a duration of 1 month postblunt trauma with a stick. On examination, his visual acuity in the right eye was 20/320 and near vision was <N36. Right eye fundus showed bullous neurosensory retinal detachment at posterior pole and retinal pigment epithelium (RPE) atrophic area temporal to fovea. Optical coherence tomography showed subretinal fluid with pigment epithelial detachment and an area of RPE and photoreceptor loss temporal to fovea. Fundus fluorescein angiography and indocyanine green angiography showed focal leaks and transmitted hyperfluorescence corresponding to the area of RPE loss. Left eye examination was unremarkable except for senile cataract of nuclear opalescence grade 3. A diagnosis of right eye bullous central serous chorioretinopathy (CSCR) and RPE sequelae postblunt trauma was made. Our patient was managed conservatively with no specific treatment for CSCR. One month later, there was improvement in vision with decrease in neurosensory detachment. The area of RPE loss remained the same with photoreceptor loss. Since this area of RPE and photoreceptor loss were temporal to fovea, our patient’s visual acuity was not affected significantly.
Purpose: Intraocular infection in patients with COVID-19 could be different in the presence of treatment with systemic corticosteroid and immunosuppressive agents. We describe the epidemiology and microbiological profile of intraocular infection in COVID-19 patients after their release from the hospital. Methods: We analyzed the clinical and microbiological data of laboratory-confirmed COVID-19 patients from April 2020 to January 2021 presenting with features of endogenous endophthalmitis within 12 weeks of their discharge from the hospital in two neighboring states in South India. The data included demography, systemic comorbidities, COVID-19 treatment details, time interval to visual symptoms, the microbiology of systemic and ocular findings, ophthalmic management, and outcomes. Results: The mean age of 24 patients (33 eyes) was 53.6 ± 13.5 (range: 5–72) years; 17 (70.83%) patients were male. Twenty-two (91.6%) patients had systemic comorbidities, and the median period of hospitalization for COVID-19 treatment was 14.5 ± 0.7 (range: 7–63) days. Infection was bilateral in nine patients. COVID-19 treatment included broad-spectrum systemic antibiotics (all), antiviral drugs (22, 91.66% of patients), systemic corticosteroid (21, 87.5% of patients), supplemental oxygen (18, 75% of patients), low molecular weight heparin (17, 70.8% of patients), admission in intensive care units (16, 66.6% of patients), and interleukin-6 inhibitor (tocilizumab) (14, 58.3% of patients). Five (20.8%) patients died of COVID-19-related complications during treatment for endophthalmitis; one eye progressed to pan ophthalmitis and orbital cellulitis; eight eyes regained vision >20/400. Fourteen of 19 (73.7%) vitreous biopsies were microbiologically positive (culture, PCR, and microscopy), and the majority (11 patients, 78.5%) were fungi. Conclusion: Intraocular infection in COVID-19 patients is predominantly caused by fungi. We suggest a routine eye examination be included as a standard of care of COVID-19.
Background: To report the clinical and angiographic characteristics of choroidal neovascularization in patients with diabetic retinopathy. Methods: Patients of type 2 diabetes mellitus with presence of choroidal neovascularization in at least one eye were retrospectively analyzed. The study eyes were divided into three groups based on presence (active or scarred) or absence of choroidal neovascularization (fellow eyes). Imaging characteristics of active choroidal neovascularization were recorded using optical coherence tomography, fluorescein, and indocyanine angiography. Central macular thickness, subfoveal choroidal thickness, and large choroidal vessel layer thickness were compared at baseline and final visit. Results: Our study reports the prevalence rate of choroidal neovascularization in eyes with diabetic retinopathy (0.27%; 36 out of 13,382 eyes). A total of 64 eyes of 32 patients (age, mean ± standard deviation: 68.5 ± 9.3 years) with baseline visual acuity of 0.69 ± 0.69 logarithm of minimum angle of resolution (Snellen equivalent 20/100) were included. Nonproliferative diabetic retinopathy (57 eyes) comprised the majority followed by proliferative diabetic retinopathy (7 eyes). Eyes with choroidal neovascularization (36, 56.25%) included both active (25) and scarred (11) choroidal neovascularization, with bilateral choroidal neovascularization in 4 patients. Type 1 choroidal neovascularization was the most common subtype of choroidal neovascularization on optical coherence tomography. Common etiologies for active choroidal neovascularization included age-related macular degeneration (3; 12%), myopia (1; 4%), and inflammatory choroidal neovascularization secondary to chorioretinitis (1; 4%). In the remaining 20 eyes, choroidal neovascularization formation was primarily due to diabetic choroidopathy. Conclusion: The prevalence of choroidal neovascularization in eyes with diabetic retinopathy is very low, with a lower prevalence of age-related macular degeneration. Diabetic choroidopathy plays a significant role in formation of choroidal neovascularization in eyes with diabetic retinopathy.
Background: To compare the vascular lesion size using optical coherence tomography angiography and indocyanine green angiography in eyes with polypoidal choroidal vasculopathy. Methods: Treatment-naïve cases (46 eyes of 44 patients) with polypoidal choroidal vasculopathy were retrospectively analyzed. The comparison of mean area of branching vascular network and polyp detection rate was done between indocyanine green angiography and optical coherence tomography angiography and correlated with various optical coherence tomography features. Results: The mean age of the study patients was 62.33 ± 10.74 years. The mean branching vascular network size was 7.47 ± 5.74 and 7.51 ± 5.69 mm² in indocyanine green angiography and optical coherence tomography angiography, respectively, with an excellent correlation (r = 0.997). Optical coherence tomography angiography overestimated (mean ± SD: 0.28 ± 0.19 mm²) and underestimated branching vascular network area (0.36 ± 0.33 mm²) in 23 eyes each as compared to indocyanine green angiography. However, the difference in branching vascular network size was not statistically significant (p = 0.53). Indocyanine green angiography and optical coherence tomography angiography could identify polyps in 43 of 46 (93.48%) and 32 of 46 (69.57%) patients, respectively. Conclusion: Branching vascular network size measurements with indocyanine green angiography and optical coherence tomography angiography were comparable and showed significant correlation, albeit the polyp identification rate was lower with optical coherence tomography angiography. Optical coherence tomography angiography may serve as a useful substitute to indocyanine green angiography in measurements of branching vascular network for photodynamic therapy and follow-up of polypoidal choroidal vasculopathy eyes.
