Eye and nervous system are anatomically and physiologically very close. About 40% of the nerve fibers in brain are correlated with visual function. Seven of twelve cranial nerves are straightly correlated with visual afferent or eye movement. Neurological diseases can affect eye in many different ways. Furthermore, systemic disorders can cause secondary neurological lesions or even primary neurological disorders, which sequentially show ocular symptoms a nd signs. Better understanding of the close relationship between eye and brain, together with intimate cooperation between ophthalmologists, neurologists, neuro surgeons and other specialties, are the key point to improve our neuro-ophthalm ology service in China.

Objective To observe the clinical manifestation and treatment effect of Coatsprime; disease in adulthood. Methods The clinical data of 18 adult patients with Coatsprime; disease from 1980 to 2006 at the department of ophthalmology, Peking Union Medical College Hospital which had been diagnosed by ocular fundus examination and fundus fluorescein angiography (FFA), were retrospectively analyzed. The follow-up period was one year. Coatsprime; response diseases in all the patiens were excluded, such as history of radiation therapy, intraocular inflammation, retinal vascular occlusion, age-related macular degeneration (AMD) and more leakage of diabetic retinopathy. The patients, 14 males and 4 females, 11 left eyes and 7 right eyes, all of them occurs in unilateral; aged from 37 to 55 years with the average age of 43 years; the initial diagnostic vision was 0.02 to 1.5, the visual value was 0.1. 17 patients (17 eyes) were treated by laser photocoagulation, 1 patient was treated by release of retinal operation with condensation. The mean follow up period was 3.7 years (ranged from 1 to 15.3 years). Results In 18 patients (18 eyes), vitreous clear in 14 eyes, vitreous few muddy in 4 years when initial diagnosis. The optic discs in 18 eyes are normal. Lesions confined to one or two quadrant, for the most are in the temporal(15/18 eyes), less are in Bice (4/18 eyes), only one eye at top; two eyes lesions involved in 2 quadrant. There are typical retinal vascular anomalies expansion, miliary aneurysm, arterial aneurysm, macroaneurysms and capillary without perfusion areas; yellowwhite hard leakage by a large block or cluster in Lesion corresponding region. More than half of the eyes with macular edema or leakage; limited retinal detachment in 4 eyes, the range was very wide in 1 eye; retinal hemorrhage in 3 eyes. After treatment the exudation or the hemorrhage were absorbed and retinas were reset. Compared the visual acuity with before treatment, mostly (64.3%) improved 2 lines or keep in 1.2-1.5, no one decreased over 2 lines. The last vision was 0.02-1.5, the visual value was 0.1. Conclusions Coatsprime; disease in adulthood diagnosed in first time has similar characteristics with children, such as vascular anomaly of retina, fundus exudation. The differences including limited area of involvement, less hemorrhages, mild damage on macular, slow development of lesions in follow-up period and better visual prognosis. （Chin J Ocul Fundus Dis，2008，24：279-282）
ObjectiveTo observe the effects of personalized clinical therapy for polypoidal choroidal vasculopathy (PCV). MethodsEighty-six eyes of 79 patients with PCV were enrolled in this study. There were 60 males (65 eyes) and 19 females (21 eyes). The average age was (64.48±13.15) years old. Best corrected visual acuity (BCVA), slit lamp ophthalmoscopy, fundus photography, optical coherence tomography (OCT), fundus fluorescein angiography (FFA) and/or indocyanine green angiography (ICGA) were measured. The average BCVA was 0.19±0..20. There were three groups in this study including photodynamic therapy (PDT) group (group A, 45 eyes), PDT and intravitreal ranibizumab injection group (group B, 31 eyes), and PDT combined with sub-Tenon's capsule triamcinolone acetonide injection group (group C, 10 eyes). Follow up begun at 1 month after the treatment. 40 eyes in group A were followed up for 1 to 12 months with the average 3.27 months.28 eyes in group B were followed up for 1 to 36 months with the average 6.68 months. 9 eyes in group C were followed up for 1 to 12 months with the average 5.67 months. Patients with recurrent or worsen lesions were followed by FFA or ICGA. Pre- and post-treatment BCVA and retinal thickness of the fovea were comparatively analyzed. ResultsAll eyes (100.0%) in group A, 20 eyes (64.52%) in group B and 9 eyes (90.00%) in group C received treatment only once. The mean BCVA at 1 month after treatment was significantly increased than the pre-treatment BCVA in all 3 groups (t=2.061, 3.262, 3.258; P<0.05), but no significant difference was found between the 3 groups (t=1.345, 0.683, 0.168; P>0.05). Compared to pre-treatment measures, the mean retinal thickness of the fovea was significantly decreased in group A and group B (t=2.239, 4.334; P<0.05), but not changed in group C (t=2.286, P>0.05) at 1 month after treatment. Thirteen eyes in group A were followed by FFA and (or) ICGA, which showed that there were 3 eyes with complete closed PCV and alleviated pigment epithelial detachment (PED), 4 eyes with partial closed PCV, 3 eyes with stable PCV and 3 eyes with worsen PCV. Ten eyes in group B were followed by FFA and (or) ICGA, which showed that there were 3 eyes with complete closed PCV, 3 eyes with partial closed PCV, 4 eyes with recurrence PCV. Five eyes in group C were followed by FFA and (or) ICGA, which showed that there were 4 eyes with complete closed PCV, 1 eyes with recurrence PCV. ConclusionAll 3 therapy strategies can stop or reduce PCV leakage and improve the visual acuity in some degree.
ObjectiveTo systematically review the efficacy and safety of photodynamic therapy (PDT) and intravitreal vascular endothelial growth factor (VEGF) inhibitors in the treatment of polypoidal choroidal vasculopathy (PCV), and to investigate the primary treatment tentatively. MethodsA systematic search of Pubmed, Embase, the Cochrane Library and the Wanfang Data was performed to identify all comparative studies that compared the outcomes of PDT alone, intravitreal VEGF inhibitors alone and combined intravitreal VEGF inhibitors and photodynamic therapy. Outcomes of interest included the regression and recurrence rate of polypoidal lesions, best corrected visual acuity (BCVA), central retinal thickness (CRT), therapeutic times, and the occurrence rate of adverse events. 2 randomized controlled trials (RCT) and 19 non-RTCs were identified. According to treatment methods, the data extracted was classified to 3 groups, analyzed with odds ratio (OR), weighted mean difference (WMD) and 95%confidence interval (95%CI). ResultsMeta-analysis suggests that the regression rate of polypoidal lesions (OR=0.34, 0.07; 95%CI=0.13-0.88, 0.02-0.36) and BCVA (WMD=0.25, 0.11; 95%CI=0.14-0.36, 0.01-0.21) in combined therapy group were significantly better than those in PDT group and intravitreal VEGF inhibitors group (P < 0.05). The recurrence rate of polypoidal lesions in PDT group was significantly lower than intravitreal VEGF inhibitors group (OR=0.35, 95%CI=0.16-0.74, P=0.006). BCVA (P=0.025) and the occurrence rate of adverse events (OR=60.36, 95%CI=6.04-603.50, P=0.000 5) in intravitreal VEGF inhibitors group were significant better than PDT group. ConclusionsCombined treatment appeared to be superior to PDT alone or intravitreal VEGF inhibitors alone. Combined treatment takes priority over all others in the primary treatment of PCV.
Objective To evaluate the efficacy and safety of intravitreal anti-vascular endothelial growth factor (VEGF) combined with photodynamic therapy (PDT) vs. photodynamic therapy for polypoidal choroidal vasculopathy (PCV).Methods A computerized search was conducted in Pubmed, OVID, Chinese Biological Medicine Database（CBM）,China National Knowledge Infrastructure （CNKI） by using key words ldquo;polypoidal choroidal vasculopathy, photodynamic therapy, intravitreal anti-VEGFrdquo; in Chinese and/or English combined with manually searching of bibliographies of pertinent articles, journals and literature reference proceedings. Randomized controlled trials (RCT) and non-RCT were collected. The search time was ranged from establishment of each database to September, 2011. The search was no 1imitation in language. The best corrected visual acuity (BCVA),resolution and recurring of lesions, decrease or complete resolution of pigment epithelial detachment （PED）,visual extinction or blindness rate,the rate of subretinal hemorrhage were analyzed by RevMan 5.0 software. Results In total, one RCT and four non-RCTs (273 patients) were included in the meta-analysis involving 148 patients in single treatment group and 125 patients in combined treatment group. The results of metaanalyses showed that there was no significant difference between two groups in the mean logarithm of minimal angle of resolution BCVA at six months ［standard mean difference=0.01, 95% confidence interval (CI): -0.12- 0.14,P=0.84］and 12 months ［standard mean difference = 0.04, 95%CI: -0.16-0.25,P=0.69 after treatment. There was no significant difference between two groups in the resolution of lesions ［odds ratio (OR)=1.38,95%CI:0.74-2.55,P=0.31］ at the months after treatment and decrease or complete resolution of PED (OR=0.67,95%CI:0.12-3.69,P=0.65) at 12 months after treatment. There was no significant difference between two groups in the recurring of lesions (OR=1.14, 95% CI:0.58-2.24,P=0.71) and lost of ge; three lines vision or blindness rate (OR=1.20, 95%CI:0.34-4.18,P=0.78) at 12 months after treatment. The rate of subretinal hemorrhage in combine treatment group was significant lower than single treatment group (OR=0.41, 95%CI:0.18 -0.94,P=0.04). Conclusions The incidence of subretinal hemorrhage occurred in patients with PCV after intravitreal anti-VEGF combined with PDT is much lower than that after single PDT.But the visual improvement, resolution of lesions and recurring of lesions of combined treatment need further studied to see if it is better than single PDT.
The pathogenesis of polypoidal choroidal vasculopathy (PCV) is still controversial. More evidence of clinical and basic research is needed to distinguish PCV from an independent disease to a subtype of age-related macular degeneration. Not only that, there are also many puzzles in the diagnosis, treatment options and prognosis of PCV. In addition to these common problems, we also face a large population with risk factors, a large number of PCV patients with multiple and complex challenges in China. There is a long way to go to reduce the damage effects of PCV on visual function. To fulfil this goal, we need make full use of the huge resources of PCV patients and turn these challenges into opportunities, and contribute the improvement of diagnosis and better understanding of PCV pathogenesis.
Radiotherapy is the prior treatment for uveal melanoma, but a major problem confronted most of the patients is radiation retinopathy, which accompanied with severe visual loss and secondary enucleation potential. There is no optium choice and normative strategy so far, the intraocular melanoma society has focused on application of anti-vascular endothelial growth factor drugs injection and glucocorticoids. This article reviews a series of potential managements for radiation retinopathy and its further stage .
ObjectiveTo compare the visual outcomes of treatment with intravitreal ranibizumab alone or in combination with photodynamic therapy (PDT) in patients with polypoidal choroidal vasculopathy (PCV). MethodsIn this retrospective and comparative study, 36 eyes of 36 patients with PCV were enrolled. Eighteen eyes received 0.5 mg (0.05 ml) ranibizumab injection only (simple injection group) and the other 18 eyes underwent combination therapy of ranibizumab injection and PDT (combination treatment group). Intravitreal ranibizumab was given at the third day after PDT. Re-treatment was considered in clinic examination. The minimum re-treatment interval was 3 months for combination therapy and 1 month for ranibizumab. Best corrected visual acuity (BCVA) of logarithm of the minimum angle of resolution (logMAR) at baseline and each follow-up visit at 1, 3, 6, 12 month was measured as a primary outcome, and complications also observed in every follow-up. ResultsNo complications occurred in these 36 patients during the treatment or follow-up, such as retinal detachment, sustained high intraocular pressure, retinal holes, intraocular inflammation, and systemic adverse reactions. The average times of ranibizumab injections of simple injection group and combined treatment group were (3.00±0.84) and (1.89±0.68) times respective, and the difference was significant (t=4.370, P=0.000). The logMAR BCVA of the first and third month after initial treatment between two groups were significant different (t=0.668, 0.940; P>0.05). However, there was no significant difference between them at the 6th and 12th month (t=2.188, 2.547; P<0.05). In the last follow-up, the logMAR BCVA were improved in simple injection group and combination treatment group compared to the pre-treatment values (t=3.351, 9.408; P=0.012, 0.000). In simple injection group, visual acuity was improved in 3 eyes (16.7%), stable in 13 eyes (72.2%) and decreased in 2 eyes (11.1%). In combination treatment group, visual acuity was improved in 4 eyes (22.2%), stable in 13 eyes (72.2%) and decreased in 1 eyes (5.6%). ConclusionsIntravitreal ranibizumab injection and combined with PDT are both effective to improve vision in patients with PCV. Visual acuity was the same between the two treatments in 3 months after initial treatment; however 6 to 12 months after first treatment, patients received PDT combined with intravitreal ranibizumab injection had better visual acuity than those received the intravitreal ranibizumab injection only.
ObjectiveTo evaluate the 3-year efficacy of photodynamic therapy (PDT) in patients with polypoidal choroidal vasculopathy (PCV). MethodsThis is a retrospective, uncontrolled case series study. Thirty-two eyes of 29 patients with PCV were enrolled. All patients were primarily treated with the first conventional PDT. For the eye with active polypoida, residual or exudative lesions in 6 month after PDT, PDT combined with intravitreal anti vascular endothelial growth factor (VEGF)or simple vitreous injection of anti VEGF therapy were used. All the patients were followed up for at least 3 years with the mean follow-up duration of 43.64±10.84 months. The best-corrected visual acuity (BCVA) in 1, 3, 6, 12, 24 and 36 months after the primary PDT, PCV recurrence rates and number of treatments were followed and analyzed. The BCVA was converted into a logarithm of the minimal angle of resolution (logMAR) for statistical analysis. ResultsDuring the 1, 3, 6, 12 months after the primary PDT, the mean BCVA were all improved with statistically significant difference(t=2.27, 4.57, 3.77, 2.37; P<0.05). During the 24 and 36 months after PDT, the mean BCVA was decreased without statistically significant difference(t=-1.29, -0.81; P>0.05). On the final evaluation at 36 months, the mean BCVA was improved in 6 eyes(18.75%), stable in 14 eyes(43.75%), and decreased in 12 eyes(37.50%). During the follow-up time, recurrence of PCV in 24 eyes (75.00%), no recurrence in 8 eyes (25.00%). There was 1 recurrence in 12 eyes (50.00%), 2 recurrences in 9 eyes (37.50%), 3 recurrences in 3 eyes (12.50%). Initial recurrences were noted in 4 eyes (16.67%) within 12 months of baseline PDT treatment; in 11 eyes (45.83%) between 13 and 24 months; in 9 eyes (37.50%) between 25 and 36 months. The mean number of PDT and anti-VEGF was 1.86±1.04 and 4.95±3.92 in all patients, respectively. ConclusionThe 3-year efficacy of PDT in patients with PCV was poor with low improvement of visual acuity and high recurrence rate of PCV.
ObjectiveTo observe the clinical features of uveal effusion syndrome (UES) and the efficacy of sclerectomy in the treatment of UES.MethodsA retrospective case series. Twenty patients (36 eyes) of UES with sclerectomy were enrolled in this study from June 2012 to December 2016 in Beijing Tongren Hospital. Among them, there were 12 males (22 eyes) and 8 females (14 eyes), with an average age of 37.8 years. All patients suffered from bilateral diseases, including 4 patients in single eye group and 16 patients in double eye group. Visual acuity, intraocular pressure, indirect ophthalmoscope, UBM, FFA combined with ICGA, A/B ultrasonography, axial length (AL) and scleral thickness were measured. All patients underwent lamellar sclerectomy, and those with exudative retinal detachment underwent four quadrant lamellar sclerectomy, followed by four quadrant full-thickness sclerectomy with the size of 1 mm × 2 mm in the center of the scleral bed. The follow-up time after operation was more than 6 months.Visual acuity, intraocular pressure and fundus examination were performed 1, 3 and 6 months after operation with the same equipment and methods before operation.ResultsThere was no obvious inflammation in the anterior chamber of all eyes, and intraocular pressure was 24-28 mmHg (1 mmHg = 0.133 kPa) in 4 eyes (11.1%). Axial length of 8 eyes (22.2%) were 16-18 mm (true microphthalmia). 12 eyes (33.3%) had scleral thickness＞1.0-1.8 mm. Visual acuity ranged from hand movement to 0.05 in 20 eyes, 0.1 to 0.3 in 10 eyes and＞0.3 in 6 eyes. Fundus examination showed peripheral choroidal and ciliary detachment; UBM examination showed annular peripheral ciliary and choroidal detachment. 32 eyes (88.9%) were complicated with exudative retinal detachment. FFA examination showed that 14 eyes (38.9%) had leopard spot changes. Compared with preoperative vision, the visual acuity improved in 28 eyes (77.8%) and remained unchanged in 8 eyes (22.2%) after surgery. Thirty-two eyes with different degrees of retinal detachment were found before surgery. After surgery, ciliary body detachment, choroidal detachment and retinal detachment were restored. Six eyes (16.7%) recurred and underwent sclerectomy again.ConclusionsThe mild symptoms and recurrent attack are the characteristics of UES. Sclerectomy is an effective method to treat UES.
