ObjectiveTo study the effects and outcomes of green diode laser therapy under indirect ophthalmoscope in the treatment of juvenile Coats disease. MethodsNineteen juvenile Coats disease patients (19 eyes) well enrolled in this study. Average age at presentation was 73.5 months (27-146 months). Best corrected visual acuity (BCVA) was ≥0.1 in 7 eyes; 0.01 to 0.09 in 8 eyes; counting finger in 3 eyes and light perception in 1 eye. The macular of all eyes was involved. There were 3 eyes with macular exudative retinal detachment, 4 eyes with sub-macular fibrosis, 1 eye with macular atrophy. Exudative area was more than two quadrants in 17 eyes, and less than two quadrants in 2 eyes. The abnormal blood vessels located in the superior or nasal-superior retina (2 eyes) or inferior or temple-inferior area (17 eyes). Exudative retinal detachment occurred in 13 eyes, in which macular was not involved in 10 eyes, and macular was involved in 3 eyes. All patients were treated with green diode laser (532 nm) ablation therapy under general anesthesia and indirect ophthalmoscope to areas of the retina telangiectasia. 3 patients received a single intravitreal 2 mg triamcinolone injection (IVTA). Average follow-up was 18.5 months (6-51 months). Main outcome measures included visual acuity, retinal vascular abnormalities, subretinal exudates and exudative retinal detachment. ResultsAmong 3 patients treated with IVTA, one needed cataract extraction and one needed pre-retinal membrane peeling surgery. After laser photocoagulation, resolution of telangiectasia lesions was achieved in all patients at the end of follow-up. Exudation was resolved in 8 eyes, reduced in 9 patients and no change in 2 eyes. Exudative detachment was resolved in 8/13 eyes, reduced in area in 3/13 eyes and no change in 2 eyes. There were 9 eyes with sub-macular fibrosis and 3 eyes with macular atrophy at the end of follow-up. The visual acuity was stable in most cases. BCVA was ≥0.1 in 6 eyes; 0.01 to 0.09 in 11 eyes; counting finger in 1 eyes and light perception in 1 eye. Compared to the normal eyes, eyes with Coats disease tended to be more hyperopic (t=3.6,P=0.003) and astigmatic (t=3.6, P=0.004), but no correction were needed for these refractive errors. ConclusionsGreen diode laser therapy under indirect ophthalmoscope can be an effective treatment for juvenile Coats disease with little complications. IVTA can be helpful, but must be used with cautions as it can induce some complications.
Objective To observe the clinical features of primary intraocular lymphoma (PIOL). Methods The clinical data of 13 patients (24 eyes) of PIOL were retrospectively analyzed. In addition to routine ophthalmic examination, auxiliary examination including fluorescein fundus angiography (FFA) and optical coherence tomography (OCT) were carried out in patients without opacity of refractive media. All the patients were underwent diagnostic vitreous surgery. Eleven patients were confirmed by cellular pathology analysis, one patient was confirmed by retinal biopsy, and one patient was confirmed by neurology biopsy. The clinical features of these patients were observed. Results There were 16 eyes of nine patients (66.7%) with primary central nervous system lymphoma and PIOL, and eight eyes of four patients (33.3%) with PIOL only. The patients included five males and eight females, with a mean age of (55.7plusmn;12.6) years. Two patients were affected unilaterally and 11 patients affected bilaterally. Their visual acuity ranged from light perception to 1.0. Fourteen eyes (58.3%) were classified as isolated vitreous inflammation type and 10 eyes (41.7%) were classified as vitreous retinal type. FFA results showed that there was no abnormalities in PIOL patients of isolated vitreous inflammation type, but there were extensive lesions of retinal pigment epithelium (RPE) observed in PIOL patients of the vitreous retinal type. OCT results showed that there were no abnormalities in PIOL of patients of isolated vitreous inflammation type, but hyperreflexia between RPE and Bruchprime;s membrane was observed in PIOL patients of vitreous retinal type. Conclusion The clinical manifestation of PIOL are diversified, mostly in bilaterally affected cases. There are extensive lesions of RPE in patients of vitreous retinal type.
ObjectiveTo investigate the clinical characteristics of 40 patients with ocular toxocariasis (OT) on the first attendance. MethodsA total of 40 consecutive patients who were clinically and serologically diagnosed with OT were retrospectively reviewed. ResultsThe mean age of patients was (12.12±10.42) years. There were 29 males and 11 females. 29 cases presented with decreased vision, 4 children with leukocoria, 2 cases with strabismus and 5 cases was found abnormal during regular eye examination. Initially 8 eyes (20%) were misdiagnosed as retinoblastoma (1 eye), Coat's disease(1 eye), cataract (2 eyes), iridocyclitis (2 eyes) and retinal detachment (2 eyes). 23 eyes had retinal detachment, 19 eyes had cataract. OT was the initial diagnosis for 15 patients (37.5%). The best corrected visual acuity (BCVA) were NLP to 0.7. Ultrasound biomicroscopy (UBM) were performed in 29 eyes, and identified peripheral granulomas in 23 eyes and adjacent tractional retinal detachment in 12 eyes. We also identified 17 cases (68.0%) with elevated IgE level among 25 patients with positive serological antibody test. ConclusionsTractional retinal detachment, vitreous opacities and cataract are the common clinical findings at the first attendance of OT patients. The adjunctive test of serum total IgE level may be helpful for the diagnosis. The application of UBM and specific IgG detection in serum and intraocular fluid, can also improve the diagnosis.
ObjectiveTo observe and analyze the clinical features and prognosis of proliferative diabetic retinopathy (PDR) with chronic myeloid leukemia.MethodsA retrospective case series study. From May 2011 to December 2020, 5 patients (10 eyes) were included in this study in Eye-ENT Hospital of Fudan University. Basic information about the patient's age, gender, diabetes history and CML history were collected. The endocrine and hematological indexes of all patients were evaluated. All the patients were undertaken visual acuity, intraocular pressure, slit lamp and fundus examination and other examinations to observe the eye conditions. Ophthalmic treatments included panretinal laser photocoagulation, intravitreal injection of anti-vascular endothelial growth factor, vitrectomy. During the follow up period from 5 months to 6 years, prognosis was observed at each office visit. During the follow up period, patients' vision, intraocular pressure, anterior segment and retinal status were observed.ResultsThere were 4 males and a female in 5 patients. The ages were from 27 to 49 years, with the mean age of 39 years. All patients were bilateral. All patients suffered type 2 diabetes for 3 months to 13 years. Four of them were diagnosed as chronic myeloid leukemia before visiting to ophthalmologists, while the other visited to ophthalmology first due to poor vision. The initial visual acuity ranged from light perception to 0.4 and 6 eyes were less than 0.1. In addition to the typical manifestations of diabetic retinopathy, such as venous tortuous dilation, exudation, microaneurysm and neovascularization, patients also presented with Roth spot as leukemic fundus manifestations. All eyes developed to PDR stage. Abnormal thickening of the neovascular membranes may occur in the lower part of the retina, with secondary traction retinal detachment. All the eyes were treated with pan retinal photocoagulation and 9 eyes underwent pars plana vitrectomy. After treatment, retina of 8 eyes kept flat. The best corrected visual acuity ranged from no light perception to 1.0, and only 4 eyes reached more than 0.2. Unfortunately, one eye lost vision because of secondary neovascular glaucoma.ConclusionsPDR patients with CMLof fundus not only have venous tortuous dilation, exudation, microaneurysm and neovascularization, also present with Roth spot as leukemic fundus manifestations. Diabetic retinopathy combined with CML could progress rapidly, and its aggravating complications such as hyperplastic membrane, vitreous hemorrhage and traction retinal detachment may result in poor visual prognosis. Early screening and treatment can help improve the prognosis of patients.
ObjectiveTo observe the clinical features and prognosis of eyes with corneal suture-related infective endophthalmitis. MethodsA retrospective interventional case series. From January 2020 to December 2021, 5 patients (5 eyes) with corneal suture-related infectious endophthalmitis diagnosed by ophthalmic examination at Department of Ophthalmology of the Eye-ENT Hospital of Fudan University were included in the study. Among them, there were 3 males and 2 females; all had unilateral disease; the mean age was 30.80±21.98 years. Sutures of 4 cases were secondary to lens related surgery and of 1 case was secondary to penetrating keratoplasty. Average retention time of corneal suture was 20.00±7.41 months. Of the 5 eyes, corneal sutures were removed in 1 eye due to redness and eye pain in another hospital; 3 eyes were loosened of the sutures in the remaining 4 eyes. The patients were given standard treatment for infectious endophthalmitis, including systemic and local anti-infective therapy; corneal suture removal, intraocular injection, and vitrectomy (PPV). In PPV, it was decided whether to give silicone oil filling according to the situation. The follow-up time after treatment was 11.00±7.38 months. The best corrected visual acuity (BCVA), B-mode ultrasound and microbial culture results of the affected eye before and after surgery were observed and analyzed.ResultsInfiltrates, ulcers, or abscesses surrounding the suture may be seen on the cornea of the affected eye. B-mode ultrasonography showed vitreous opacity, preretinal cords, and spherical wall edema in the entire segment of the affected eye. The results of vitreous humor culture were positive in 3 eyes, which were Streptococcus viridis, Staphylococcus hominis subspecies, Staphylococcus epidermidis. After treatment, all the intraocular infections in the affected eyes were successfully controlled, and there were no cases of enucleation of ocular contents or enucleation. Before treatment, the BCVA of the affected eye was from no light perception to counting fingers; after treatment, 2 eyes had BCVA＞0.3. ConclusionsInfiltration, ulcers or abscesses around the sutures can be seen in the cornea of corneal suture-related infective endophthalmitis patients, which are related to the long-term retention of the sutures in the eye. Most of the affected eyes have loose sutures when they go to the doctor; timely treatment can effectively control the infection, and some eyes have good visual prognosis.
Objective To observe the Fourierdomain optical coherence tomography（FD-OCT）characteristic of idiopathic epiretinal membrane (ERM) and its correlation with the patients visual acuity. Methods The 116 eyes (112 patients) with idiopathic epiretinal membrane were included in this study. All the patients had undergone examination of visual acuity (LogMAR chart), ocular fundus (direct ophthalmoscope and fundus pre-set lens), and FD-OCT (Zeiss HD-OCT) with the speed of 27 000 A scan/s,area of 6.0 mmtimes;6.0 mm, and mode of 512times;128. The central fovea thickness (CFT), volume (V), average thickness (AT) were collected from the OCT readings, and the fovea thickness (FT) was measured manually. Data were analyzed using SPSS 16.0. Results The traction on retina caused by ERM can be divided into 3 types according to the OCT findings: no traction (9.48%), tangential traction (84.48%) and tangential traction with anteriorposterior traction (6.04%). A total of 97 eyes (83.62%) had retinal edema (diffuse or cystoid) and the edema located at the outer nuclear layer(ONL), outer plexiform layer(OPL)and inner nuclear layer (INL) . A total of 14 eyes (12.07%) had retinal nerve fiber layer (RNFL) schisis and 27 eyes (23.28%) had inner segment/outer segment junction (IS/OS) impairment. Statistic analysis revealed that BCVA was not related to the age, gender, types of traction, presence of IS/OS damage or RNFL schisis (Pgt;0.05), but was related with CFT(Plt;0.05). Conclusions Idiopathic ERM can exert different types of traction on the macular, and cause different types of retinal lesions. OCT is a useful tool to measure these lesions. CFT reading is closely related to patients' visual acuity.
ObjectiveTo evaluate the safety and efficacy of the intravitreal methotrexate treatment in patients with primary vitreoretinal lymphoma (PVRL). MethodsRetrospective non-comparative interventional case series. Fourteen patients (26 eyes) with biopsy-proven PVRL were included in the study. All patients received examination of Snellen chart visual acuity, fundus color photography and optical coherence tomography (OCT). Among the 24 eyes with recordable visual acuity, 17 eyes has initial visual acuity≥0.1 (0.45±0.20) and 7 eyes with initial visual acuity ranged from light perception to hand movement. The vitreous opacities and (or) subretinal yellowish-white lesions and retinal pigment epitheliumuplift were observed in all eyes. All eyes were treated with intravitreal methotrexate (4000 μg/ml, 0.1 ml) injections according to a induction-consolidation-maintenance regimen. For 26 treated eyes, each received an average of (11.5±6.3) injections. Twenty eyes had finished theintraocular chemotherapy, while 6 eyes had not. Eight of 20 eyes were clinically confirmed free of tumor cells by diagnostic vitrectomy, 12 eyes were still with tumor cell involvement.The follow-up was ranged from 2 to 48 months, the mean time was 18 months. The examination of BCVA, fundus color photography and OCT were performed. No tumor cell was defined as clinical remission. Visual acuity was scored as improved or declined obviously (improved or declined 2 lines) or mild improved or declined (changed within 2 lines). ResultsTwenty eyes achieved clinical remission after (3.5±3.6) injections, 12 eyes of 20 eyes with tumor cell involvement before chemotherapy achieved clinical remission after (5.8±3.0) injections. The mean visual acuity of seventeen eyes with initial visual acuity 0.1 in induction phase and at the end of treatment were 0.36±0.23 and 0.56±0.20, respectively. Compared with before treatment, the visual acuity was mild declined in induction phase (t=1.541, P>0.05), but mild improved at the end of treatment (t=2.639, P<0.05). The visual acuity at the end of treatment in 7 eyes with initial visual acuity<0.1 was ranged from no light perception to 0.1. Of 14 patients, 2 patients have been fatal because of brain lesions progression at 42 and 48 months after diagnosis of primary central nervous system lymphoma. No ocular recurrence was noted during the follow-up in 20 eyes who finished intraocular chemotherapy. ConclusionsPVRL patients can achieve clinical remission after (3.5±3.6) injections by intravitreal chemotherapy of methotrexate, and the visual acuity improved mildly. No ocular recurrence was found during follow-up.
ObjectiveTo observe the changes of varicella zoster virus (VZV)-DNA load in aqueous humour samples in VZV-induced acute retinal necrosis (ARN) in the early stages of antiviral treatment. MethodsA retrospective observational clinical study. From April 2016 to April 2018, 24 patients with 24 eyes of VZV-induced ARN who were diagnosed by Department of Ophthalmology, Eye and ENT Hospital of Fudan University and received complete aqueous humor sampling were included in the study. Among them, there were 13 males with 13 eyes, 11 females with 11 eyes; 12 left eyes and 12 right eyes; the age was 52.0±9.5 years old (39-71 years old). The time from the onset of ocular symptoms to the diagnosis of ARN was 16.6±6.1 days (7-30 days). Best-corrected visual acuity (BCVA) and ultra-wide-field fundus imaging were performed in all affected eyes. The BCVA examination was carried out using the Snellen visual acuity chart, which was converted into the logarithm of the minimum angle of resolution (logMAR) visual acuity. All patients were given intravitreal injection of 40 mg/ml ganciclovir 0.1 ml (including 4 mg of ganciclovir), 2 times a week, until the active necrotizing retinal lesions subsided, at most after the diagnosis 4 weeks, with a maximum of 9 injections. The follow-up period was 12.8±5.6 months. The aqueous humor samples were collected at presentation and 4, 7, 14, 21, 28 days after the initiation of antiviral therapy, and the VZV-DNA load was detected by real-time quantitative polymerase chain reaction. A plateau phase and a logarithmic reduction phase of the DNA load changes were observed after antiviral treatment began. Wilcoxon rank sum test was used to compare and analyze the differences in BCVA between the eyes at baseline and last follow-up. ResultsThe mean viral load at presentation was 8.6×107±1.3×108 copies/ml. The initial plateau phase last for an average of 7.4±2.4 days. In the following logarithmic reduction phase, the mean slope of the decline in viral load was －0.13±0.04 log/day, and the expected time for half reduction of the initial viral load was 2.5±0.7 days. After 28 days antiviral treatment, the viral load decreased to 1.7×105±1.8×105 copies/ml. In the course of the disease, rhegmatogenous retinal detachment occurred in 16 eyes. Before treatment and at the last follow-up, the logMAR BCVA of the affected eye was 1.1±0.6 and 0.8±0.7, respectively. The results of correlation analysis showed that the logMAR BCVA at the last follow-up was correlated with the initial VZV-DNA load (r=0.467, P=0.033). ConclusionThe VZV-DNA load in the aqueous humor of eyes with VZV-induced ARN is significantly decreased after antiviral treatment, which is closely related to the clinical process of ARN.
