Idiopathic central serous chorioretinopathy. (1/183)

Idiopathic central serous chorioretinopathy (ICSC) is usually seen in young males with Type A personality. Clinical evaluation of the macula with fundoscopy and biomicroscopy, coupled with fluorescein angiography establishes the diagnosis. Indocyanine green angiographic studies have reinformed that the basic pathology lies in choriocapillaries and retinal pigment epithelium. Most of the ICSC resolve completely in four months, and some of them could resolve early with direct photocoagulation of the leaking site. Oral steroids have no role, and could even cause an adverse reaction.  (+info)

The pathogenesis of choroidal neovascularization in patients with age-related macular degeneration. (2/183)

Laser photocoagulation and several experimental treatments for choroidal neovascularization (CNV) in patients with age-related macular degeneration attempt to ablate the neovascularization, but do not address underlying angiogenic stimuli. As a result, recurrences are a major problem. Drug treatment to counter the growth of CNV would be a major advance, but its development is impeded by lack of knowledge concerning the stimuli and other molecular signals involved in the pathogenesis of CNV. Herein we explore clues that can be gleaned from clinical, epidemiological, pathological, and experimental data. These suggest that abnormalities of the extracellular matrix of retinal pigmented epithelial (RPE) cells may promote a pro-angiogenic RPE phenotype that contributes to the development of CNV. This provides a general hypothesis that can be tested, but it is also necessary to test hypotheses regarding the specific alterations in gene expression that contribute to CNV. Identification of alterations in gene expression will provide targets for rational design of drug treatment.  (+info)

Autosomal dominant macular atrophy at 6q14 excludes CORD7 and MCDR1/PBCRA loci. (3/183)

PURPOSE: Localization of the gene responsible for autosomal dominant atrophic macular degeneration (adMD) in a large pedigree UM:H785. METHODS: Standard ophthalmologic examinations were performed. Microsatellite markers were used to map the disease gene by linkage and haplotype analyses. RESULTS: The macular degeneration in this family is characterized by progressive retinal pigment epithelial atrophy in the macula without apparent peripheral involvement by ophthalmoscopy or functional studies. Acuity loss progressed with age and generally was worse in the older affected individuals. The rod and cone function remained normal or nearly normal in all tested affected members up to 61 years of age. The phenotype in our family has characteristics similar to Stargardt-like macular degeneration with some differences. Haplotype analysis localized the disease gene in our adMD family to an 8-cM region at 6q14, which is within the 18-cM interval of STGD3 but excludes cone-rod dystrophy 7 (CORD7; centromeric) and North Carolina macular degeneration and progressive bifocal chorioretinal atrophy (MCDR1/PBCRA; telomeric). The mapping interval overlaps with that of recessive retinitis pigmentosa (RP25). CONCLUSIONS: These results implicate at least three genetically distinct loci for forms of macular degeneration that lie within a 30-cM interval on chromosome 6p11-6q16: CORD7, adMD, and MCDR1/PBCRA. Because the critical interval for the adMD family studied overlaps with STGD3 and RP25, these loci could be allelic.  (+info)

Fluorescein angiographic features of choroidal insufficiency in anterior ischemic optic neuropathy. (4/183)

Anterior ischemic optic neuropathy(AION) is known to be caused by circulatory disturbance in the anterior optic nerve(AON). Because the AON shares blood supply from the paraoptic short posterior ciliary artery with peripapillary choroid, the authors investigated the angiographic evidences of combined choroidal insufficiency in patients with acute AION. Fundus fluorescein angiograms from 30 eyes from 28 patients with acute AION were enrolled in this study. The diagnosis of acute AION was based primarily on angiographic evidences of filling delay of optic nerve head and the various clinical features, such as decreased visual acuity, visual field defects, afferent pupillary defect, and optic disc swelling. Angiographic evidences of combined choroidal filling delay were as follows: 1) circular or localized filling delay of peripapillary choroid in 15 eyes (50%), 2) generalized filling delay of posterior pole in 11 eyes (36.7%), 3) filling delay of unilateral choroid divided by watershed zone in 5 eyes (16.7%), and 4) choriocapillary filling delay in 10 eyes (33.3%). In this study, various types of choroidal insufficiency in patients with AION were observed, which helped us to differentiate AION from the other various diseases of the anterior optic nerve.  (+info)

Bullous variant of idiopathic central serous chorioretinopathy. (5/183)

BACKGROUND: Spontaneous bullous serous retinal detachment (RD) with subretinal exudation complicating idiopathic central serous chorioretinopathy (ICSC) is a rare and infrequently described clinical entity. Clinical observations are described on this variant form in 11 patients, the largest series reported to date. METHODS: 13 eyes of 11 Indian patients having this entity were followed up clinically and angiographically for 12-24 months (retrospective, longitudinal). None of the patients had any previous history of other diseases nor were they on any medications. Four eyes received laser treatment (group A); nine eyes were not treated (group B). RESULTS: All 11 patients were male, aged 23-49 years (median 37 years). The clinical and photographic records revealed subretinal exudation and inferior bullous serous RD complicating ICSC with evidence of large, single or multiple, leaking retinal pigment epithelial detachments (PEDs) in all the cases. In group A, resolution of serous RD occurred in 12 weeks (median) with a visual recovery of >/=20/30 in three out of four eyes while in group B resolution of serous retinal detachment was observed in 14 weeks (median) with eight out of nine eyes achieving a visual acuity of >/=20/30. Subretinal fibrosis developed in two eyes in group A and none of the eyes in group B. CONCLUSION: The disease is an exaggerated form of ICSC and can occur spontaneously without any history of corticosteroid therapy. Recognition of this atypical presentation is important to avoid inappropriate treatment. These observations suggest that with respect to the duration of the disease and the final visual outcome laser therapy offers no additional benefit over the natural course of this variant form of ICSC.  (+info)

CT-revealed choroidal effusions as a sign of carotid cavernous fistula. (6/183)

Choroidal effusions may appear as subtle abnormalities on CT scans. Recognition of choroidal effusions, however, is critical because they may be an early sign of ocular pathologic abnormality. After detection, the various causes of choroidal effusions, such as carotid cavernous fistulas, ocular hypotony, tumors, and inflammatory conditions, should be considered.  (+info)

Choroidal thickness changes during altered eye growth and refractive state in a primate. (7/183)

PURPOSE: In the chick, compensation for experimentally induced defocus involves changes in the thickness of the choroid. The choroid thickens in response to imposed myopic defocus and thins in response to imposed hyperopic defocus. This study was undertaken to determine whether similar choroidal changes occur in the primate eye with induced refractive errors. METHODS: Thirty-three common marmosets were used. Eyes in 26 monkeys served as untreated control eyes, and eyes in 7 received 3 weeks of monocular lid suture to induce changes in eye growth and refractive state. Refractive errors were measured using refractometry and retinoscopy, and axial ocular dimensions, including choroidal thickness, were measured using high-frequency A-scan ultrasonography. Eyes were measured before the lids were sutured and at frequent intervals after lid opening. RESULTS: In the marmoset, choroidal thickness ranges from 88 to 150 microm and increases significantly during the first year of life. Monocular lid suture initially results in short, hyperopic eyes that then become elongated and myopic. In these animals the choroids of both the experimental and the fellow control eyes also increase in thickness with age but additionally show interocular differences that vary significantly with the relative changes in vitreous chamber depth and refraction. In eyes that are shorter and more hyperopic than control eyes the choroids are thicker, and in eyes that are longer and more myopic than control eyes the choroids are thinner. CONCLUSIONS: In marmosets, the thickness of the choroid increases during postnatal eye growth. Superimposed on this developmental increase in choroidal thickness there are changes in thickness that are correlated with the induced changes in eye size. These changes are small (<50 microm) in comparison with those observed in the chick, contributing to less than a diopter change in refractive error.  (+info)

Early treatment with cyclosporin in serpiginous choroidopathy maintains remission and good visual outcome. (8/183)

AIMS: To describe management and clinical outcomes of serpiginous choroidopathy treated primarily with cyclosporin at a tertiary uveitis referral centre METHODS: A case series of 14 eyes of seven patients with serpiginous choroidopathy with follow up ranging from 1.3 to 13 years is described. All patients had fundus lesions consistent with serpiginous choroidopathy, were investigated for systemic disease, had fluorescein angiography, and were treated with combined immunosuppressive therapy including cyclosporin. RESULTS: No patients suffered significant loss of acuity after starting systemic immunosuppression with cyclosporin as the primary agent. All but one patient achieved remission and were able to stop medications with no recurrences in the follow up period. Side effects from cyclosporin were well tolerated and there were no serious complications from immunosuppression. CONCLUSIONS: Cyclosporin is a safe and effective option with which to manage serpiginous choroidopathy. Significantly, adequate immunosuppression can result in clinical remission and cessation of therapy in some patients.  (+info)

Purpose: We observed and analyzed the morphologic characteristics of polypoidal lesions and abnormal branching vascular network (BVN) in patients with polypoidal choroidal vasculopathy (PCV) by optical coherence tomography angiography (OCTA). Methods: A retrospective observational case series was done of patients with PCV. All patients were scanned with a 70-kHz spectral-domain OCT system using the split-spectrum amplitude-decorrelation angiography (SSADA) algorithm to distinguish blood flow from static tissue. The OCTA images of these patients were compared to those from indocyanine green angiography (ICGA). Semiautomated segmentation was used to further analyze the polypoidal lesion and the BVN. Results: We studied 13 eyes of 13 patients 51 to 69 years old. A total of 11 patients were treatment-naive. Two patients had multiple anti-VEGF injections and one underwent photodynamic therapy (PDT). Optical coherence tomography angiography was able to detect the BVN in all cases. Using ...
Neovascular age-related macular degeneration (nAMD) is the commonest cause of severe visual impairment in older adults in Caucasian white populations. Polypoidal choroidal vasculopathy (PCV) has been described as a separate clinical entity differing from nAMD and other macular diseases associated with subretinal neovascularization. It remains controversial as to whether or not PCV represents a sub-type of nAMD. This article summarizes the current literature on the clinical, pathophysiological and epidemiological features and treatment responses of PCV and compares this condition to nAMD. Patients with PCV are younger and more likely Asians, and eyes with PCV lack drusen, often present with serosanguinous maculopathy or hemorrhagic pigment epithelial detachment, and have differing responses to photodynamic therapy and anti-vascular endothelial growth factor (VEGF) agents. There are also significant differences in angiographic and optical coherence tomography features between PCV and nAMD. ...
In Doppler OCT images, polypoidal lesions could be clearly detected at the corresponding location of lesions in the ICGA images. By the impervious feature to dye leakage, Doppler OCT imaging could identify the more detailed vascular structure in the polypoidal lesions. Polypoidal lesions in Doppler OCT images were consisted of focal aneurysmal dilation in the vascular network. Polypoidal lesions were located in the retinal pigment epithelial detachment in 13 eyes, in the choroid in one eye, and in both the retinal pigment epithelial detachment and the choroid in one eye. Mean area of polypoidal lesions in ICGA images (0.13 mm2) was significantly larger than Doppler OCT images (0.04 mm2)(P = 0.0007). After the intravitreal injection of aflibercept, areas of polypoidal lesions in ICGA images were decreased in 14 of 15 eyes, while Doppler OCT could clearly detect this therapeutic effect in all eyes. Mean reduction rates were 65.8 % in ICGA images and 66.6 % in Doppler OCT images. Reduction rate in ...
Polypoidal choroidal vasculopathy (PCV) is one of the disorders within the pachychoroid spectrum diseases. The presence of pachyvessels is one of the characteristics of pachychoroid disorders. However, the relationship between the presence of pachyvessels and the clinical characteristics of PCV eyes has not been determined. The purpose of this study was to determine the relationship between the presence of choroidal pachyvessels and the clinical characteristics of eyes with PCV. The medical records of patients who were diagnosed with PCV and were treatment-naïve were reviewed. Fluorescein and indocyanine green angiography, fundus photography, spectral domain optical coherence tomography (SD-OCT), and enhanced depth imaging OCT (EDI-OCT) were used to obtain images of the choroid. The presence of pathologically dilated outer choroidal vessels, pachyvessels, was determined by ICGA images. These pachyvessels were confirmed to correspond with the large choroidal vessels in the EDI OCT images. The PCV eyes
Purpose: To describe the clinical characteristics and outcome of eyes with extrafoveal polypoidal choroidal vasculopathy (PCV) treated with argon laser. Design: Prospective cohort, noninterventional study. Methods: A prospective study of Asian patients with extrafoveal PCV, confirmed on indocyanine green angiography and treated with argon laser with and without anti-vascular endothelial growth factor (VEGF) therapy. Patients were followed-up over 12 months with visual, angiographic, and structural outcomes recorded. Results: Of the 93 eyes with PCV at baseline, 33 eyes (35.5%) in 31 patients had extrafoveal involvement and were treated with argon laser. Foveal involvement with fluid or blood at baseline was apparent in 23 eyes (69.7%), despite the extrafoveal location of 1 or more polyps. Of these 33 eyes, 12 (36.4%) also received anti-VEGF injections (median, 2.5 injections) over the 12-month period. Two eyes received photodynamic therapy rescue during subsequent follow-up and were excluded for ...
Polypoidal choroidal vasculopathy (PCV) is a degenerative macular disease. The study determined the topographical concordance in the areal extent of PCV, defined by indocyanine green angiography (ICGA), and the corresponding outcomes from spectral-domain optical coherence tomography (SD-OCT) and microperimetry, in 25 individuals (25 eyes) who had undergone 3 months of anti-vascular endothelial growth factor treatment. The differential light sensitivity within 10° eccentricity was evaluated by Pattern Deviation probability analysis. The concordances and proportional areal extents of the abnormality for ICGA, SD-OCT and microperimetry were compared. The concordance in the areal extent between all three modalities was 59%. The median concordance between ICGA and microperimetry was 60%; between ICGA and SD-OCT, 70%; and between SD-OCT and microperimetry, 72%. SD-OCT and microperimetry each identified a greater areal extent (,20%) compared to ICGA in 13 and 19 eyes, respectively. A greater areal ...
Polypoidal choroidal vasculopathy (PCV) is a disease of the choroidal vasculature.  It is present in both men and woman of many ethnicities, characterized by serosanguineous detachments of the pigmented epithelium and exudative changes that can commonly lead to subretinal fibrosis. Evidence supports that symptomatic patients with PCV can have complete regression without severe vision loss with photodynamic therapy (PDT) and anti-VEGF treatment.  
PURPOSE To compare the 12-month real-world visual and disease activity outcomes of eyes with polypoidal choroidal vasculopathy (PCV) treated with a combination of photodynamic therapy (PDT) and anti-vascular endothelial growth factor (VEGF) injections (combination group) versus those eyes treated with anti-VEGF monotherapy alone with rescue PDT being used as required (monotherapy group). DESIGN Database comparative observational study. PARTICIPANTS Eyes with PCV as graded in the Fight Retinal Blindness! database from Australia, New Zealand, Singapore, and Switzerland. METHODS Clinical information from a multisite, international registry of neovascular age-related macular degeneration was analyzed with an intention-to-treat approach.

Results Exudative branching vascular networks were characterised as occult choroidal neovascularisation (38 eyes) or classic choroidal neovascularisation (7 eyes) on fluorescein angiography. Intravitreal bevacizumab maintained or improved vision in 38 eyes (84%) over 12 months and in 36 eyes (80%) over 24 months, although the mean visual acuity at 12 and 24 months did not differ significantly compared with baseline. Complete resolution of macular fluid was achieved continuously in 26 eyes (58%) during 24 months. Sixteen eyes (36%) responded once to treatment but became unresponsive to additional injections for recurrent exudation. Three eyes (7%) were refractory to treatment throughout follow-up. Cystoid macular oedema eventually developed in 10 eyes and was a poor prognostic sign for visual outcome. ...
Polypoidal choroidal vasculopathy is considered to be one of the subtypes of the neovascular age-related macular degeneration, especially frequent in Asians. The disease is clinically manifested by the recurrent serosanguineous pigment epithelial detachment and polypoid reddish-orange nodules visible in the posterior segment of the globe. The association of polypoidal choroidal vasculopathy with the spectrum of age-related macular degeneration raises some controversies due to the relatively rare occurrence in its case of several characteristic findings such as drusen, pigment changes or RPE atrophy. Choosing the optimal therapeutic option for each patient the individual characteristics of the patient's disease and the availability of diagnostic and therapeutic tools should be considered ...

This is a 2-step process combining a light-activated drug called Visudyne (verteporfin) with light from a cold laser directed onto the abnormal area of retina. Once activated, the drug causes the abnormal vessels to close off. PDT does not cause direct damage to the surrounding retina. Therefore, it can be used to treat new vessels that are under the centre of the macula (fovea).. Several treatments are needed to keep the leaking blood vessels closed and stop the progression of wet MD. Close follow up and monitoring is needed to determine if further treatment is required.. Unlike anti-VEGF drugs with which the vision is usually maintained, patients undergoing PDT continue to lose vision in the first 6 months. Their vision then stabilises so that the eye does not progress to severe vision loss.. PDT is now rarely used to treat ordinary wet MD. It is sometimes used in conjunction an anti-VEGF drug to treat a type of MD called polypoidal choroidal vasculopathy (PCV) as some of these cases do not ...

To study the macular sensitivity after half-dose verteporfin photodynamic therapy in patients with resolved central serous chorioretinopathy using the automated static perimeter. Prospective consecutive case study of 24 patients with resolved central serous chorioretinopathy was performed. The macular sensitivity was measured using a conventional automated static perimeter with the Swedish interactive threshold algorithm 10-2 and foveal threshold. Best corrected visual acuity, intraocular pressure, fundus examination, macular thickness, and volume were also examined. The mean macular sensitivities of the affected eyes and their normal fellow eyes were calculated and compared. P,0.05 was considered statistically significant. The mean macular sensitivities of the affected eyes were lower than the normal fellow eyes with a statistically significant difference in all areas of the study (P,0.05). Best corrected visual acuity improved significantly from pretreatment (0.26±0.3 logMAR) to posttreatment ...

A clinical research study published in The Lancet has reported that the treatment of eplerenone should be discontinued for the use of serous chorioretinopathy (CSCR) in ophthalmic practice. An analysis of the study reported that both primary and secondary outcomes of the trial indicated that there was no benefit of eplerenone treatment over placebo. Following the research, a commentary on the report stated that: This result is an important outcome that will change clinical practice. The trial results should prompt ophthalmologists to stop prescribing eplerenone to treat CSCR and encourage patients to participate in future trials of other potential interventions. The study was led by Prof. Andrew Lotery at the University of Southampton, and Prof. Sobha Sivaprasad at the Moorfields Eye Hospital NHS Foundation Trust, UK.. The aetiology of central serous chorioretinopathy (CSR) has an estimated 10 new cases per 100,000 men and 2 cases per 100,000 women in the population however, there is no clear ...

Central serous chorioretinopathy (CSCR) is the fourth most common retinopathy after age-related macular degeneration, diabetic retinopathy and branch retinal vein occlusion.[1] CSCR typically occurs in males in their 20s to 50s who exhibit acute or sub-acute central vision loss or distortion. Other common complaints include micropsia, metamorphopsia, hyperopic (most common) or myopic shift, central scotoma, and reduced contrast sensitivity and color saturation.[2] No underlying pathophysiologic mechanisms have been proven, but CSCR is thought to occur due to hyper-permeable choroidal capillaries, which, in association with retinal pigment dysfunction, cause a serous detachment of the neurosensory retina. Recurrence occurs in about 31% patients with CSCR,[3] though the recurrence rate has been quoted to be up to 50% in most texts.

A major interest in a well-known and not uncommon disorder of the macula is central serous chorioretinopathy. This is a disorder that occurs in young adults who under stress or who have a particular risk of leakage and swelling of the choroidal circulation, leading ultimately to detachment of the macula.. Numerous clinical features as well as imaging characteristics have been the subject of The Macula Foundation research in the past several decades. While the pathogenesis or precise causative factors are still poorly understood, The Macula Foundation investigators have reported on particular classifications, imaging features, and treatment modalities. It is the most common macular disorder that is seen beginning in young adulthood.. ...

The macula in the left eye shows a small puddle of fluid involving the fovea. This represents a detachment of the neurosensory retina from the RPE. OCT confirmed this finding. These findings are classic for idiopathic central serous chorioretinopathy (ICSC), also called central serous retinopathy. ICSC typically occurs in 20- to 45-year-old males who exhibit type A personalities.1 Although our patient is age 50, it does not change our diagnosis; ICSC has been reported in patients as old as age 60.2 It occurs more commonly in males than females (a 10-to-1 ratio), and there is often a strong relationship between ICSC and emotional stress, although we do not know whether stress triggers the condition.1 Migraine headaches also have been associated with the onset of these neurosensory detachments. On examination, the macula usually exhibits a round or oval area of elevation of the neurosensory retina. This can be very subtle and easily missed if the detachment is small or if there is a very shallow ...

There is no known effective treatment for the disease. Laser photocoagulation, which effectively burns the leak area shut, is sometimes suggested. In many cases the leak is very near the central macula, where photocoagulation would leave a blind spot. Additionally, a better long term outcome has not been demonstrated with photocoagulation. So more often than not the condition goes untreated. Transpupillary thermotherapy has been suggested as a lower-risk alternative to laser photocoagulation in cases where the leak is in the central macula. Any ongoing corticosteroid treatment should be stopped. Additionally, a new anti-microbial treatment will likely be recommended soon in light of recent findings regarding Helicobacter pylori. CSR sufferers usually find their own ways to manage the condition, which may include stress reduction and changes in nutrition. ...
CSR is a fluid detachment of macula layers from their supporting tissue. This allows choroidal fluid to leak into the subretinal space. The buildup of fluid seems to occur because of small breaks in the retinal pigment epithelium. CSR is sometimes called idiopathic CSR which means that its cause is unknown. Nevertheless, stress appears to play an important role. An oft-cited but potentially inaccurate conclusion is that persons in stressful occupations, such as airplane pilots, have a higher incidence of CSR. The type A personality has also been linked to this condition. However, the statistics may be skewed by the fact that CSR often goes undiagnosed or misdiagnosed; airline pilots and so-called type A people are demonstrably exacting, demanding people with (certainly in the case of pilots) better-than-average vision. They are more likely than the general population to notice the sometimes-subtle degradation of vision caused by CSR and insist on a believable diagnosis of it. People who need ...

Our understanding of pachychoroid disease has expanded greatly thanks to multimodal clinical imaging technologies. Cross-sectional and en face depth-resolved imaging, such as enhanced depth imaging (EDI) OCT, Swept-Source OCT (SS-OCT), and OCT angiography (OCTa), have enabled a deeper appreciation for the role of the choroid in a wide-range of macular disorders.. Pachychoroid disease is a phenotype encompassing a spectrum of macular conditions which manifest common choroidal findings, and includes pachychoroid pigment epitheliopathy, central serous chorioretinopathy, peripapillary pachychoroid syndrome and focal choroidal excavation. This phenotype of great clinical relevance in that it may predispose patients to macular neovascularization (pachychoroid neovasculopathy). Many patients with pachychoroid disease develop this type 1 neovascularization as a late-stage manifestation. In some eyes, these vessels may form a branching network that can give rise to aneurysmal type 1 neovascularization ...
