RESUMO

PURPOSE: To investigate the imaging and clinical features of polypoidal choroidal vasculopathy (PCV) with pulsation. METHODS: The PCV eyes were classified into pulsatile and nonpulsatile PCV groups according to the pulsation on indocyanine green angiography. Imaging features including the dye filling time of the polyp and clinical features were compared. RESULTS: A total of 75 eyes were classified into the pulsatile PCV (30 eyes) and the nonpulsatile PCV (45 eyes) groups. The initial filling time and complete filling time of the polyp of the pulsatile PCV group (2.59 ± 0.93 and 8.33 ± 3.42 seconds) were shorter than those of the nonpulsatile PCV group (4.11 ± 1.87 and 10.63 ± 3.81 seconds, P < 0.001 and P = 0.010, respectively). The pigment epithelial detachment height of the pulsatile PCV group (414.90 ± 377.15 µ m) was greater than that of the nonpulsatile PCV group (247.81 ± 164.07 µ m, P = 0.030). The pulsatile PCV group showed a higher prevalence of subretinal hemorrhage (43.33%) after intravitreal injection than the nonpulsatile PCV group (13.95%, P = 0.005) during 12 months. The mean number of injections during 12 months of the pulsatile PCV group (5.48 ± 1.46) was greater than that of the nonpulsatile PCV group (4.09 ± 1.21, P < 0.001). CONCLUSION: Eyes with pulsatile PCV showed shorter filling time of the polyp, greater pigment epithelial detachment height, higher prevalence of subretinal hemorrhage, and more intravitreal injection numbers during 12 months. These might suggest that PCV has distinct imaging and clinical features according to the polyp pulsation.

RESUMO

Purpose: To report choroidal caverns in patients affected by recessive Stargardt disease (STGD1) and to investigate its clinical features. Methods: Retrospective analysis of STGD1 patients recruited at the Regional Reference Center for Hereditary Retinal Degenerations at the Eye Clinic in Florence from 2012 to 2017. Patients included in the study underwent a complete ophthalmic examination including best-corrected visual acuity, color fundus photography, fundus autofluorescence, optical coherence tomography (OCT) and OCT angiography. Results: Eighty-six patients (172 eyes) were included in the study. Twenty-three eyes (13.3%) of 21 patients presented choroidal caverns. The total number of detected choroidal caverns was 63. Choroidal caverns were only present in patients with stage III and IV STGD. Interestingly, patients with choroidal caverns presented larger macular atrophy (20.53 ± 16.9 mm2 vs. 18.11 ± 20.39 mm2), worse visual acuity (1.03 ± 0.29 vs. 0.83 ± 0.26), and a thinner choroidal thickness (245.9 ± 88.7 vs. 266.0 ± 110.5 µm). Conclusions: Choroidal caverns are present only in the advanced stage of STGD1, and a possible degenerative origin of the finding has been hypothesized.

RESUMO

PURPOSE: Widefield swept-source optical coherence tomography (OCT) imaging was used to characterize choroidal thickness and vascularity at baseline in proliferative diabetic retinopathy (PDR) and longitudinally after panretinal photocoagulation (PRP). METHODS: Patients with treatment-naive PDR were imaged at baseline and at 1 week, 1 month, and 3 months after PRP. Previously validated algorithms were used to calculate the mean choroidal thickness (MCT) and choroidal vascularity index (CVI) in 5 regions of 12 mm × 12 mm scans. RESULTS: Fourteen PDR eyes were included. Baseline MCT in PDR eyes did not differ significantly from normal eyes, but CVI measurements in PDR eyes were lower in all regions (P < 0.001-0.008). After PRP, MCT measurements in PDR eyes were significantly lower at 1 month and 3 months in all regions (P < 0.001-0.005) except the fovea (P = 0.074). However, CVI measurements did not change over time in any region after PRP. CONCLUSION: The choroid in PDR eyes has a smaller CVI than that in normal eyes. After PRP, the choroidal thickness decreases outside the fovea, but the CVI remains constant, which suggests that a relative decrease in choroidal vascularity persists. These widefield swept-source OCT results are consistent with choroidal alterations found in histopathological reports of diabetic choroidopathy.

RESUMO

This retrospective study aimed to evaluate the factors affecting recurrence and visual prognosis in patients with treatment-naïve subfoveal polypoidal choroidal vasculopathy (PCV). Patients who had received three consecutive intravitreal injections of ranibizumab or aflibercept and had reached remission were enrolled. They were divided into a group without recurrence (group 1, 26 eyes) and a group with recurrence (group 2, 121 eyes) and followed up for at least 5 years. Patients in group 2 received additional treatment for worsening. Logistic regression analysis revealed that a young age of onset (P = 0.001), high choroidal vascularity index (CVI; P = 0.019), and presence of choroidal vascular hyperpermeability (CVH; P = 0.037) were associated with a low risk of recurrence. Multiple regression analysis revealed that recurrence (P = 0.001), greatest linear dimension (P = 0.003), and polyp configuration (single or cluster; P = 0.043) were associated with final visual acuity. Patients without recurrence had a lower age of onset and higher CVI than those with recurrence, and they tended to have CVH. In addition, patients with recurrence, large lesion, and cluster polyps had worse final visual acuity than those without these factors. CVI and CVH may be used to predict recurrence of PCV.

RESUMO

SIGNIFICANCE: Although rarely seen, clinicians should closely monitor patients, especially pregnant patients with focal choroidal excavation (FCE), as it can convert between subtypes and has been linked to pachychoroidal disease and potential for vision loss. PURPOSE: This study aimed to report a case of the conversion of conforming FCE to nonconforming FCE with spontaneous resolution in a pregnant female. CASE REPORT: A 35-year-old Indian woman presented with a slightly decreased vision in the right eye. The patient was 3 months pregnant at this visit. Her ocular history included stable conforming FCE in both eyes that was diagnosed 1 year earlier. Retinal pigmentary changes were noted in both eyes and consistent with previous examinations as being conforming FCEs in both eyes. Optical coherence tomography through the pigmented changes revealed FCE in the right eye with overlying serous fluid, with the left eye showing stable conforming FCE. She was diagnosed with a nonconforming FCE in the right eye secondary to her pregnancy. She was monitored with subsequent visits showing spontaneous resolution of the fluid and conversion back to a conforming FCE. CONCLUSIONS: This case highlights the conversion of a conforming FCE to a nonconforming FCE with spontaneous resolution in a pregnant female. Similarities are seen in terms of pathophysiology with central serous chorioretinopathy, a fellow pachychoroidal disease, which also has pregnancy as a risk factor. Risk factors in pregnant patients such as increased cortisol and increased ocular blood flow may play an important part in the pathophysiology of the conditions, as they both result in choroidal hyperpermeability. Frequent monitoring and follow-up times are suggested for the patients. Lifelong monitoring is also indicated, as reoccurrences have been reported. Further research is needed at this time to elucidate the exact etiology of FCE and conversions between conforming and nonconforming FCE.

RESUMO

PURPOSE: To evaluate associations between choroidal thickness and features of polypoidal choroidal vasculopathy (PCV) lesions based on multimodal imaging. METHODS: This cross-sectional analysis included treatment-naive PCV eyes from a prospectively recruited observational cohort. Associations between of subfoveal choroidal thickness (SFCT) and qualitative and quantitative morphologic features of PCV lesions on color fundus photographs, indocyanine green and fluorescein angiography, and spectral-domain optical coherence tomography were evaluated. RESULTS: We included 100 eyes with indocyanine green angiography-proven PCV. Subfoveal choroidal thickness showed a bimodal distribution with peaks at 170 µm and 350 µm. There was a significant linear increase in the total lesion area (P-trend = 0.028) and the polypoidal lesion area (P-trend = 0.030 and P-continuous = 0.037) with increasing SFCT. Pairwise comparisons between quartiles showed that the total lesion area (4.20 ± 2.61 vs. 2.89 ± 1.43 mm2, P = 0.024) and the polypoidal lesion area (1.03 ± 1.01 vs. 0.59 ± 0.45 mm2, P = 0.042) are significantly larger in eyes in Q4 (SFCT ≥ 350 µm) than eyes in Q1 (SFCT ≤ 170 µm). Although there was no significant linear trend relating SFCT to best-corrected visual acuity, pairwise comparisons showed that eyes in Q4 (SFCT ≥ 350 µm) have significantly worse vision (0.85 ± 0.63 vs. 0.55 ± 0.27 logMAR, P = 0.030) than eyes in Q2 (SFCT 170-260 µm). CONCLUSION: Total lesion areas and polypoidal lesion areas tend to be larger in eyes with increasing SFCT. Choroidal background may influence the phenotype or progression pattern of PCV.

RESUMO

Purpose: To report a rare case of Vogt-Koyanagi-Harada (VKH) patient with bilateral annular choroidal detachment and describe ultra-widefield angiographic findings.Method: Case report.Results: A 61-year-old male was diagnosed as VKH based on ocular signs and neurologic findings. Annular choroidal detachment anterior to the equator was noted in both eyes. Ultra-wide field (UWF) fluorescein angiography revealed multiple leakages at posterior pole and disc with dye pooling at the margin of choroidal detachment. Late-phase UWF indocyanine green angiography (ICGA) revealed hyperpermeability with dilated veins and many vortex ampullae obscured by detached choroid. Choroidal detachment and other manifestations improved after a high-dose systemic steroid treatment. UWF ICGA after the treatment revealed decreased choroidal vessel caliber with visible vortex ampullae.Conclusion: Vortex obstruction and choroidal vein dilatation were observed in a VKH patient with choroidal detachment, which might be related to its pathophysiology.

RESUMO

Purpose: To report a case of ocular dirofilariasis causing extensive chorio-retinal damage.Method: Surgical removal of the worm and identification of the same by microscopic examinationand polymerase chain reaction.Results: The worm was identified as Dirofilaria repens.Conclusion: Ocular dirofilariasis is an arthropod borne parasitic infestation affecting the subconjunctival tissue and anterior chamber. Vitreous involvement in Dirofilaria is very rare. Dirofilaria repens can cause extensive chorio-retinal damage resembling diffuse unilateralsubacute neuroretinitis.

RESUMO

PURPOSE: To report the occurrence of bilateral choroidal detachments due to the use of ipilimumab and pembrolizumab immunochemotherapeutics to treat widely metastatic cutaneous melanoma and to raise awareness about this potentially vision-threatening adverse drug event. METHODS: A 77 year-old man presented with acute onset, painless, and bilateral blurry vision. He had started ipilimumab and pembrolizumab 2 weeks prior for Stage IV metastatic cutaneous melanoma. RESULTS: Clinical examination revealed bilateral choroidal detachments. After discussion with the patient's medical oncologist, the patient discontinued both medications and began oral prednisone to expedite visual recovery. The choroidal detachments subsequently resolved, and visual acuity improved 2 weeks later. CONCLUSION: Ipilimumab and pembrolizumab have been reported both in monotherapy and in combination to cause a wide variety of ophthalmic adverse events. This is the first report of choroidal detachments as a complication.

RESUMO

PURPOSE: To determine the significance of both massive choroidal invasion and optic nerve invasion (retrolaminar [(RL]+cut end [CE]) as a criterion for classifying high metastatic potential retinoblastoma and their relationship with other known histopathological high-risk features. METHODS: A retrospective review of 650 eyes diagnosed as retinoblastoma over a 10-year period. In our study, there is male predominance and a higher percentage of the poorly differentiated tumors. The age of most of the patients ranges from 1 month to 8 years with a median age of 2 years. RESULTS: There were 24% of eyes with massive choroidal invasion and 18% of eyes with optic nerve invasion up to the cut end. On performing Cox-proportional hazard analysis, it was found that massive choroidal invasion in association with optic nerve invasion up to the cut end was an independent prognostic parameter. On Kaplan-Meier analysis, overall survival had reduced in patients having both massive choroidal invasion and an optic nerve cut end invasion along with orbital invasion (P < .05). CONCLUSION: The presence of massive choroidal invasion in association with optic nerve cut end invasion (RL+CE) could be used as a better prognostic predictor in assessing retinoblastoma patients with high metastatic potential and need to be kept for longer follow up.

RESUMO

Purpose: This study aims to assess choroidal vascularity index (CVI) and choroidal thickness (CT) in patients diagnosed with type 1 diabetes mellitus (DM) and compare them with healthy control subjects.Methods: This retrospective and cross-sectional study includes 43 patients diagnosed with type 1 DM and 43 healthy age/gender-matched subjects as the control group. Enhanced depth imaging optical coherence tomography (EDI-OCT; Spectralis, Heidelberg Engineering GmbH, Heidelberg, Germany) images of all participants were analyzed. CT measurements of five different points (subfoveal, 500 µm temporal, 1500 µm temporal, 500 µm nasal, and 1500 µm nasal to the fovea) were obtained. Choroid images were divided into luminal (LA) and stromal areas (SA) determined by image binarization method. Choroidal vascularity index (CVI) was defined as the ratio of LA to total choroid area (TCA). The effects of age, HbA1c, fasting plasma glucose, duration of DM, mean blood pressure, intraocular pressure, and axial length measurements on CVI were investigated.Results: There was no significant difference between any of the CT measurements of the groups (all p > .05). There was no significant difference between the groups according to TCA (0.82 ± 0.24 vs. 0.80 ± 0.19; p = .065), LA (0.54 ± 0.17 vs. 0.55 ± 0.16; p = .123) and SA (0.28 ± 0.06 vs. 0.25 ± 0.07; p = .068). However, patients had significantly lower CVI compared to control subjects (66.07 ± 3.19 vs. 68.89 ± 2.85, p < .001). Univariate linear regression model revealed that there was a negative correlation between disease duration and CVI (standardized beta coefficient: -0.416, p = .006).Conclusion: According to our findings, reduced CVI may indicate subclinical dysfunction in choroid of patients with type 1 DM.

RESUMO

Purpose: To measure the subfoveal choroidal thickness (SFCT) and assess intereye subfoveal choroidal thickness difference (ISFCTD) in patients with unilateral Fuchs Uveitis Syndrome (FUS) compared with healthy controls.Methods: Forty-two patients with unilateral FUS were included in this observational retrospective study. SFCT in both eyes was measured in patients and controls using optical coherent tomography. The measurements were analyzed and compared as follows: for SFTC-affected eye vs fellow eye (FUS); affected eye (FUS) vs right control eye; fellow eye (FUS) vs left control eye; for ISFCTD - FUS patients vs controls. In addition, measurement error analysis was performed.Results: No significant differences in SFCT between the compared eyes were found (p > .05). The mean ISFCTD was 57.24 ± 40.8 µm in FUS patients and 30.33 ± 25.48 µm in controls (p < .,001).Conclusion: The ISFCTD was higher in FUS patients than in controls. There were no statistically significant differences in SFCT between the compared eyes.

RESUMO

PURPOSE: To investigate the effect of blood flow in the temporal optic nerve head (ONH) and peripapillary chorioretinal atrophy (PPA) zone on central visual field (VF) defects and progression in eyes with open-angle glaucoma (OAG) and myopic disc. DESIGN: Retrospective longitudinal medical chart review. PARTICIPANTS: This study comprised 366 eyes of 245 OAG patients with myopic disc, followed for at least 2 years with at least 5 reliable VF tests. OCT and laser speckle flowgraphy (LSFG) were performed at baseline. METHODS: We analyzed the relationship between temporal ONH-tissue mean blur rate (MBR), temporal PPA-tissue MBR, total deviation (TD)-central, and TD-central slope with a linear mixed-effects model. Additionally, we investigated background factors influencing temporal PPA-tissue MBR. Main outcome measures were basic ophthalmic and systemic variables, baseline ONH-tissue MBR, baseline PPA-tissue MBR, baseline TD, and TD slope. RESULTS: Lower temporal ONH-tissue MBR was associated with both worse TD-central and faster TD-central slope (ß = 0.30, P < 0.001; ß = 0.18, P = 0.001, respectively). However, lower temporal PPA-tissue MBR was only associated with faster TD-central slope (ß = 0.15, P = 0.005). Lower ONH-tissue MBR and lower PPA-tissue MBR were significant independent contributors to worse TD-central slope, after adjusting for potential confounding factors (ß = 0.12 to 0.15, P < 0.05). The multivariate analysis showed that lower pulse rate, larger temporal PPA area, and lower circumpapillary retinal nerve fiber layer thickness were associated with lower PPA-tissue MBR (P < 0.05). CONCLUSIONS: Measurement of systemic variables and LSFG analysis might help clinicians to predict central VF defect severity and progression in OAG eyes with myopic disc.

RESUMO

PURPOSE: To characterize peripapillary choroidal microvasculature dropout (MvD) in patients with compressive optic neuropathy (CON) as compared with those with open-angle glaucoma (OAG) using OCT angiography (OCTA). DESIGN: Cross-sectional, observational study. PARTICIPANTS: Eighty-eight eyes of 44 patients with CON; 88 eyes of 88 patients with OAG matched by age, spherical error, and OCT-determined retinal nerve fiber layer thickness (RNFLT); and 88 eyes of 44 control participants matched by age and spherical error. METHODS: Peripapillary microvasculature was evaluated, and peripapillary vessel density was measured in en face images segmented into inner-retinal and choroidal layers using swept-source OCTA. An MvD was defined as a focal sectoral capillary dropout with no visible microvascular network in the choroidal layer. MAIN OUTCOME MEASURES: Comparative characteristics of MvD in eyes with CON and OAG. RESULTS: Microvasculature dropout was observed in 30 eyes (34.1%) of 22 patients (50.0%) with CON, and in 48 eyes of 48 patients (54.5%) with OAG (P = 0.011). All MvDs in the CON group were located in the temporal parapapillary sector, whereas MvDs in the OAG group were located in the temporal-inferior (n = 36) and temporal-superior (n = 4) sectors. At their locations, MvDs in the CON group were accompanied by significant reductions in retinal vessel density and RNFLT, but this was not observed in the OAG group. The presence of MvD was associated significantly with female gender (P = 0.020) and thinner global retinal nerve fiber layer (P = 0.006) in the CON group, but not in the OAG group. CONCLUSIONS: OCT angiography of the peripapillary area showed retinal and choroidal microvasculature impairment in patients with both CON and OAG. However, the features and associated characteristics of MvD differed between these groups, suggesting that the pathogenesis of peripapillary microvascular impairment may be diverse.

RESUMO

PURPOSE: To compare the efficacy between initial 3-monthly intravitreal conbercept monotherapy and combination intravitreal conbercept with photodynamic therapy (PDT) for polypoidal choroidal vasculopathy (PCV). METHODS: This is a retrospective, comparative study which involved 65 PCV eyes of 65 patients. According to the therapeutic regimen, the PCV patients were divided into two groups: 32 eyes with naive PCV received a PDT after the first intravitreal injection of conbercept (IVC) followed by pro re nata (prn) retreatment (combination group), and 33 eyes with naïve PCV received 3-monthly IVC monotherapy followed by prn regimen (IVC monotherapy group). All patients completed at least 6 months of monthly follow-up. RESULTS: At month 6, best-corrected visual acuity (BCVA) improved significantly (P < 0.05) in both groups compared with that at baseline; the mean changes of BCVA between the IVC monotherapy group and combination group have no significant difference (-0.22 ± 0.22 vs. -0.17 ± 0.22 LogMAR, P = 0.38). The central retinal thickness (CRT) decreased significantly in the two groups (P < 0.05), with no difference between the two groups (P = 0.24). The complete regression rate of polyps was 58.6% (17 out of 29 eyes) in the IVC monotherapy group and 80.65% (25 out of 31 eyes) in the combination group, respectively (P = 0.09, χ-squared test). The combination group required significantly fewer injections than the IVC monotherapy group (3.09 ± 0.89 vs. 3.67 ± 0.74, P = 0.006). CONCLUSION: Conbercept monotherapy significantly improved visual acuity and effectively regressed polyps during 6-month follow-up time in the treatment of PCV.

RESUMO

BACKGOUND: Intravitreal injections are the most common treatment modality for several retinal pathologies. Despite endophthalmitis being the most feared complication, antibioprophylaxis remains controversial in intravitreal injections. METHODS: This was a retrospective study done for a period of 2 years from 1st January 2017 to 31st December 2018 in B. P Koirala Lions Centre for Ophthalmic Studies (BPKLCOS) among patients receiving intravitreal bevacizumab. The intravitreal injection was given by a single surgeon. It included 503 eyes which received intravitreal bevacizumab over a period of 2 years without pre and postoperative antibiotics. RESULTS: Out of 503 eyes studied over a period of 2 years without antibiotic prophylaxis the rate of endophthalmitis was 0.0019% which is very low compared to the other studies with rate of endophthalmitis between 0.019-0.09%. CONCLUSION: The risk of endophthalmitis was low even without pre/post-operative antibiotics. Intravitreal injection can be given safely without pre-operative and post-operative antibiotics. Trial Registration not applicable as it is a retrospective study.

RESUMO

PURPOSE: To describe retinal and choroidal vascular changes, and choroidal stroma variations occurring in focal choroidal excavation (FCE). METHODS: Study design was a cross-sectional case series. Consecutive patients affected by FCE and healthy controls were recruited. All patients underwent complete ophthalmologic assessment and multimodal imaging, including structural optical coherence tomography and optical coherence tomography angiography. Choroidal thickness and stromal index were calculated from structural optical coherence tomography images. Moreover, we measured vessel density values of the superficial capillary plexus, deep capillary plexus and choriocapillaris at the level of the macula. RESULTS: Twenty-two patients (28 eyes; mean age 57.2 ± 16.4) and 28 control eyes (mean age of 56.5 ± 9.8) were included. Five patients (23%) were asymptomatic, whereas 17 patients (77%) complained of visual symptoms. FCE was associated with choroidal neovascularization in 10 eyes (35%). Choroidal stromal component was lower in FCE patients than controls, whereas choroidal thickness was unremarkable. Stromal index values calculated in the region proximal to the FCE was significantly lower than the values obtained from the external region. Deep capillary plexus vessel density was lower in FCE than controls. Choriocapillaris was altered in the region surrounding the FCE, whereas it was normal in the external region. CONCLUSION: Deep capillary plexus and choriocapillaris plexus were significantly altered in FCE patients. Moreover, choroidal stroma was significantly reduced in the areas closer to FCE compared to the surrounding choroid in patients, as well as compared to healthy controls, suggesting the hypothesis of weakening of the architectural support, creating a more friable point, which can favor FCE development.

RESUMO

The most effective way to control glaucoma is by lowering intraocular pressure (IOP) in order to prevent the progression of the disease. Glaucoma drainage devices (GDDs) are surgical option reserved for refractory cases and have been designed to address known complications of conventional filtering surgery. They are, however, associated with a higher rate of complications related to early hypotony and late corneal decompensation. In the case of the commonly used Baerveldt Glaucoma Implant (BGI), techniques exist in an attempt to prevent early postoperative hypotony but can be highly variable and surgeon dependent. Moreover, the additional steps required can result in unstable IOP in the immediate postoperative period. In 2014, Villamarin and colleagues described for the first time an adjustable GDD, called the eyeWatch implant, designed to better control IOP fluctuations and avoid hypotony during the early postoperative period via magnetic control of the device tube lumen. This innovation provides the possibility to adjust the amount of aqueous humor outflow after device implantation in a noninvasive manner. We report the case of an 83-year-old patient with advanced pseudoexfoliative glaucoma, referred to our tertiary center because of disease progression despite topical therapy and having undergone deep sclerectomy. First, a BGI was implanted but was unfortunately complicated by a 3-month chronic refractory hypotony from day 8, and choroidal detachment despite medical management, choroidal drainage, and viscoelastic injections. After 3 months, the decision was made to rescue the situation with an eyeWatch adjunction to the BGI. Postoperatively, the IOP was successfully controlled through fine adjustments of the eyeWatch opening position, until the last visit 8 months after the rescue, with complete resolution of the choroidal detachment and without any medications. This demonstrates that the eyeWatch may offer an answer not only to the immediate postoperative hypotonic phase of the GDD surgery but also to the later cystic bleb hypertonic phase.
