Secondary choroidal neovascularization due to choroidal osteoma after 9 years follow-up.

BACKGROUND: Choroidal osteoma is a benign intraocular tumor that can increase risk of developing choroidal neovascularization. The visual prognosis is influenced by the tumor location, decalcification status, overlying RPE atrophy, presence of choroidal neovascularization, persistence of subretinal fluid and occurrence of subretinal hemorrhages. CASE PRESENTATION: The authors present a 40-year-old woman diagnosed with choroidal osteoma of the right eye. Her best corrected visual acuity was 12/20 but decreased to 5/20 due to secondary choroidal neovascularization after 8 years follow up. Fundus examination revealed an enlarged choroidal osteoma in most margins at posterior pole with schistose hemorrhage beside macula. Optical coherence tomography angiography revealed unique features in the vascular changes of choroidal neovascularization in choroidal osteoma in the outer retinal layer and choroid capillary layers, and subretinal neovascularization. Indocyanine green fluorescence angiography showed there was hypo-fluorescence at the peripapillary with faint hyper-fluorescence at the macular, corresponding to the location on the fundus photograph. The patient received 3 injections of intravitreal ranibizumab. After 1 year follow up, her visual acuity of the right eye was 18/20 and the CNV had regressed. CONCLUSIONS: We present the findings and treatment of a case of choroidal osteoma with secondary choroidal neovascularization. Optical coherence tomography angiography combined with FFA and ICGA is used to analysis the characteristics of secondary choroidal neovascularization. Optical coherence tomography angiography can reveal some unique characteristics in the vascular changes compared to fundus fluorescein angiography.

Swept Source-Optical Coherence Tomography Angiography for Management of Secondary Choroidal Neovascularization in Punctate Inner Choroidopathy.

The purpose was to demonstrate the diagnostic and therapeutic feasibility of swept source-optical coherence tomography angiography (SS-OCTA) by picturing neovascular changes secondary to a rare white dot syndrome following long-term intravitreal ranibizumab (IVR). A 28-year-old Caucasian myopic female presented with visual loss in her right eye only. The clinical examination and multimodal imaging including spectral domain (SD)-OCT, blue-peak autofluorescence, fluorescein, and indocyanine green angiography (HRA Spectralis, Heidelberg Engineering; Heidelberg, Germany) as well as SS-OCTA (DRI Triton, Topcon; Tokyo, Japan) led to the diagnosis of idiopathic punctate inner choroidopathy with secondary subfoveal choroidal neovascularization (CNV). In addition to oral corticosteroids, a pro re nata regimen with IVR was initiated and guided by repeated SD-OCT and SS-OCTA. Six IVR were administered based on functional SS-OCTA en face scans illustrating vessel transformation and downsizing of the CNV area while SD-OCT B-scans were inconclusive as indirect signs of activity were absent throughout the follow-up period. SS-OCTA provided new possibilities for monitoring vessel development. IVR was managed based on vessel density as displayed by SS-OCTA.

Peripheral combined hamartoma of the retina and retinal pigment epithelium with remote peripapillary choroidal neovascular membrane.

PURPOSE: To describe the first reported case of combined hamartoma of the retina and retinal pigment epithelium (CHRRPE) associated with a remote choroidal neovascular membrane (CNVM). OBSERVATIONS: A 19-month-old girl with a normal prenatal and infantile history presented with esotropia of the left eye. Fundus examination demonstrated a large, elevated, charcoal-colored lesion in the nasal equatorial retina. There was dragging of the nasal retinal vessels and a retinal fold, presumed to have resulted from nasal traction from the lesion. There was also subretinal hemorrhage in the peripapillary macula. Multimodal imaging demonstrated a peripapillary choroidal neovascular membrane (CNVM) underlying the retinal fold. There was no leakage within the tumor or secondary retinal neovascularization. Examination of the fellow eye was unremarkable. The patient was diagnosed with peripheral CHRRPE with associated peripapillary CNVM. She was treated with serial intravitreal bevacizumab to the affected eye which resulted in a reduction in leakage from the CNVM and resolution of the subretinal hemorrhage. The CHRRPE remained stable on follow-up. CONCLUSIONS: Peripheral CHRRPE can rarely be associated with a remote CNVM.

Assessment of the efficacy of photodynamic therapy in patients with chronic central serous chorioretinopathy.

PURPOSE: The aim of this prospective clinical study was to evaluate the anatomical and functional results of the treatment of 54 eyes with chronic form of central serous chorioretinopathy (CSC) using photodynamic therapy in a reduced (half) verteporfin (HD-PDT) dosing regimen. MATERIALS AND METHODS: Our prospective study included 54 eyes of 52 patients (40 males, 12 females) at an average age of 50.1 years (median 49.5, range 30-75 years) treated at the Ophthalmology Clinic of the First Faculty of Medicine and Military University Hospital in Prague from January 2012 to January 2018 for chronic form of CSC with a minimum disease duration of 3 months. In our study, we evaluated the improvement of the best corrected visual acuity (BCVA) and central retinal thickness (CRT) before treatment and at 1, 3, 6 and 12 months after HD-PDT. RESULTS: The mean baseline BCVA was 68.91 ± 10.5 ETDRS letters (median 71; range 35-85) and the mean baseline CRT was 385.6 ± 118.5 µm (median 367, 5 µm; range 245-1000 µm). At the end of the follow-up period, the average BCVA was 79 ± 11 ETDRS letters (median 82; range 38-93). The improvement in BCVA before and after treatment was statistically significant in all measurements (p < 0.0001). The mean CRT at the end of the follow-up period was 263.5 ± 52 µm (median 258.5 µm; range 162-404 µm). The decrease in CRT at all timepoints was statistically significant compared to baseline (p < 0.0001). In our set of patients, at the end of the follow-up period, the retinal finding was improved or stabilized in 50 eyes (92.6 %). In this study, we observed in 2 cases the development of secondary choroidal neovascularization (CNV). CONCLUSION: HD-PDT is a long-term safe and effective method of treating chronic forms of CSC. However, despite a reduced dose of verteporfin, complications may occur.

Intravitreal anti-VEGF treatment for choroidal neovascularization secondary to traumatic choroidal rupture.

BACKGROUND: So far only single cases with short follow-up have been reported on the use of intravitreal anti-VEGF for traumatic choroidal neovascularizations (CNV). This paper reports a large case series of patients with CNV secondary to choroidal rupture after ocular trauma receiving intravitreal anti-VEGF (vascular endothelial growth factor) injections. METHODS: Fifty-four patients with unilateral choroidal rupture after ocular trauma diagnosed between 2000 and 2016 were retrospectively evaluated. Eleven patients with CNV secondary to choroidal rupture were identified. Five eyes with traumatic secondary CNV were treated with anti-VEGF and were systematically analysed. The other 4 patients with inactive CNV underwent watchful observation. RESULTS: Four men and one woman with a mean age of 29 years (SD 12.4; range 19-45) had intravitreal anti-VEGF therapy for traumatic CNV. Another 4 patients with a mean age of 37 years (SD 6.6; range 31-46) presented with inactive CNV and did not receive specific treatment. In all 9 cases the mean interval between the ocular trauma and the diagnosis of CNV was 5.7 months (SD 4.75; range 2-12). In the treatment group per eye 4.2 injections (SD 3.2; range 1-8) were given on average. Four eyes were treated with bevacizumab and one eye with ranibizumab. Regression of CNV was noted in all eyes. In 4 eyes visual acuity (VA) improved, one eye kept stable visual acuity. CONCLUSIONS: Here, we present the up to now largest case series of traumatic CNV membranes treated with anti-VEGF injections with a mean follow-up period of 5 years. Intravitreal anti-VEGF therapy seems to be safe and effective for secondary CNV after choroidal rupture. Compared to exudative age-related macular degeneration fewer injections are needed to control the disease. TRIAL REGISTRATION: Retrospective registration with local ethics committee on 21 March 2019. Trial registration number is 19-1368-104.

Clinical evaluation of neovascular and non-neovascular chronic central serous chorioretinopathy (CSC) diagnosed by swept source optical coherence tomography angiography (SS OCTA).

PURPOSE: To evaluate the clinical characteristics of eyes with chronic central serous chorioretinopathy based on swept source optical coherence tomography angiography (SS OCTA). METHODS: Twenty-nine eyes presenting with chronic central serous chorioretinopathy (CSC) were examined with the Topcon SS OCTA, using the DRI optical coherence tomography (OCT) Triton machine, and were classified as neovascular or non-neovascular CSC depending on whether a vascular pattern was detected in the outer retina on OCT angiogram. The two groups were compared based on the following clinical findings: best corrected distance and reading visual acuity (BCDVA, best corrected reading acuity (BCRA)), rate of subretinal fluid, intraretinal fluid, hyperreflective flat pigment epithelial detachment (PED), and serous PED. RESULTS: Of 29 eyes with chronic CSC, 10 (34.5%) showed a neovascular pattern, suggesting neovascular CSC, in the outer retina of SS OCTA. Eyes with neovascular CSC showed a significantly worse initial and final BCDVA, with a mean value of 0.39 ± 0.20 logMAR (Snellen equivalent 20/49) and 0.33 ± 0.36 logMAR (Snellen equivalent 20/43), compared to eyes with non-neovascular CSC with a mean value of 0.16 ± 0.15 logMAR (Snellen equivalent 20/29) and 0.04 ± 0.11 logMAR (Snellen equivalent 20/22) (p < 0.05), respectively. Final mean BCRA was 0.14 ± 0.20 logRAD for non-neovascular CSC compared to 0.34 ± 0.28 logRAD (p = 0.031) for neovascular CSC. The mean time between the first and final visits was 3 years for both groups. The mean anti-VEGF injection rate was 6.4 for neovascular CSC and 2.9 for non-neovascular CSC, whereas 26.3% of non-neovascular CSC eyes had an additional half fluence photodynamic therapy (PDT). CONCLUSION: SS OCTA provides a promising CNV detection rate, secondary to chronic CSC, in a clinical setting. Neovascular CSC is associated with a worse outcome in terms of visual and reading acuity compared to non-neovascular CSC.
