Objective To observe the therapeutic effect of photodynamic therapy (PDT) and transpupillary thermotherapy (TTT) on circumscribed choroid hemangioma (CCH).Methods Clinical data of 32 patients (33 eyes) with CCH diagnosed by ocular fundus examination, fundus fluorescein angiography (FFA),indocyanine green angiography (ICGA),optical coherence tomography (OCT) and Bultrasound examination were retrospectively analyzed.Before the therapy the selected cases had best corrected visual acuity (BCVA) of fingercounting/15 cm-0.2,the sizes of 2-10 disc diameter (DD) and serous retinal detachment.Twentyone patients (22 eyes) whose tumor located at the posterior pole except for the papillomacular bundle and arch ring area underwent TTT.The parameters of TTT included: Iris 810 nm infra red diode laser，7001200 mW,60 s,and 1-3 spots. Eleven patients (11 eyes) with tumor located at the posterior pole except for the papillomacular bundle and arch ring area underwent. After 15 minutes of intravenous injection with Visudyne, laser irradiation with the wavelength of 689 nm was performed with the time of 83-123 s. The followup period was 12-48 months with the mean of 25.6 months.BCVA and results of indirect ophthalmoscopy,fundus photogrphy,FFA,ICGA,OCT and B ultrasound examination were exanmined and anlyzed.Results In the 22 eyes in TTT group, the BCVA improved in 15 and kept unchanged in 7;the results of fundus examinations showed healed retina and atrophy tumor with greywhite organized scar;the results of FFA revealed no fluorescence leakage and scar fluorescence dyeing of the lesion in later period；the results of OCT indicated disappeared retinal detachment, completely absorbed subretinal liquid and increased reflection of choroid tumor with scar；the results of Bultrasound examination showed no retinal detachment and atrophy tumor.In 11 eyes in PDT group,the BCVA improved in 9, unchanged in 2;the results of fundus examinations showed atrophy tumor with pigmentation；the results of FFA revealed disappeared fluorescence leakage；the results of OCT indicated completely absorbed subretinal liquid；the results of B-ultrasound examination showed atrophy tumor.Conclusions Both TTT and PDT can make the tumor atrophy,improve BCVA or keep it still;but apply to different area.
Objective To evaluate safty and effects of a single photodynamic therapy(PDT) for circumscribed choroid hemangiomas. Methods We performed a retrospective analysis of 11 eyes of 10 patients who were reated with single standard PDT. Of 10 patients, 6 males, 4 females；mean 40 .2 years old；of 11 eyes, 6 left eyes, 5 right eyes; 1 patient who both eyes wer e involved. Follow-up time varied from 1month to 14months, mean 6.2 month. Results After treatment, all tumors show various degrees of regression and subretinal fluid were absorbed completely or partly. The visual acuity of 8 eyes improved; that of 3 eyes unchanged. Conclusions PDT is effective modality for circumscribed choroid hemangiomas. (Chin J Ocul Fundus Dis,2008,24:111-113)
Objective To observe the clinical features and investigate the method of treatment for vasoproliferative tumors of the retina (VTR). Methods Retrospectively analyzed the clinical data of 17 VTR patients (17 eyes) who had undergone examination of ocular funds, fundus fluorescein angiography (FFA), and B ultra-scanning examination, including 1 treated by photodynamic therapy (PDT) and 7 treated by photocoagulation. Pathological examination and photocoagulation was performed on 1 patient who was found with VTR when undergoing vitrectomy. Results Single or multiple red or yellowish tumor lesions were found in ocular fundi of all of the 17 eyes associated with intraretinal and subretinal exudations (100％), haemorrhages (n=10, 58.82％), retinal detachment (n=5, 29.41％), exudative changes at the macula (n=9, 52.94％), and vitreous haemorrhage (n=1, 5.88％). The lesions located at the inferio-temporal quadrant was found in 8 eyes (47.06％), at the superio-temporal quadrant in 7 (41.18％), and at the inferio-and superio-nasal quadrant in 1 (5.88％), respectively. The result of B ultra-scanning indicated that 16 patients had the lesions on the retina. The result of FFA demonstrated the leakage of the fluorescein of the tumor at the early stage. The tumor became smaller in size of the patient treated by PDT,and in 7 patients undergone photocoagulation, 2 revealed slightly shrunken lesions and 1 less leakage. Conclusions The clinical features of VTR were red or yellowish tumedity lesions in ocular fundi with intraretinal and subretinal exudations. The examination of B ultra-scanning and FFA may help to diagnose VTR. PDT and photocoaguation are effective on controlling the lesion but are of no avail for the improvement of visual acuity.

Objective To evaluate the effect of transpupillary thermo therapy (TTT) on the treatment of intraocular tumors. Methods A total of 50 patients with intraocular tumors, including 37 choroidal hemangioma, 2 retinal capillary hemangioma, 5 choroidal osteoma, 4 choroidal melanoma, and 2 retinoblastoma (RB) underwent TTT and were followed up for 1～20 months. Results In 30 patients with choroidal hemangioma (average follow-up was 5.1 months), 29 (96.7%) had pigment scarring in different levels and the retinal detachemnts were partly or completely recovered; 1 had no obvious improvement. The visual acuity was unchanged in 24 (80.0%) patients, improved in 41 (13.3%) and declined in 2 (6.7%). In 2 patients with retinal capillary hemangioma, no effect was found. In 5 eyes (4 patients) with choroidal osteoma (average follow-up was 6 months), no change of the tumor was found in 1 and the atrophic spots were seen in 4; the visual acuity was unchanged in 3, improved in 1 and declined in 1. In 4 patients with choroidal melanoma (average follow-up was 8 months), the tumor was shrunken in 1, unchanged in 2, and enlarged in 1; the visual acuity was unchanged in 2 and declined in 2. In 2 patients with RB, RB was totally shrunken in 1 and partly shrunken in 1. Visual acuity of one child patient who was followed up for 20 months could not be examined, and was unchanged in another one who was followed up for 3 months. No severe complications were found in the patients during the treatment and the follow-up. Conclusions TTT is effective for the treatment of some intraocular tumors except retinal capillary hemangioma. It is a kind of potential treatment for intraocular tumors with few side-effect.

Objective lt;brgt;To evaluate the clinical effect of transpupillary thermotherapy (TTT) on circumscribed choroidal hemangioma (CCH). Methods lt;brgt;The clinical data of 12 eyes of 12 patients with CCH treated with TTT were retrospectively analysed. Infrared diode laser Iridex, oculight SLX was used in TTT at 810 nm and power between 220 and 1000 mW with a beam diameter of 1.2 or 2.0 or 3.0 mm, with 1 to 2 minutes of exposure time. The visual acuity, subretinal fluid, complication ,thickness and hyperfluorescence of CCH were observed pre- and postoperatively in the treated eyes. The average period of follow-up was 10 months (6-16 months). lt;brgt; lt;brgt;Results lt;brgt;Among the 8 eyes with peripheral retinal detachment in 12 cases of CCH the peripheral subretinal fluid was completely absorbed in 6 eyes, and partially absorbed in 2 eyes after TTT treatment. In 8 patients undergone ultrasonography, the mean value of tumor thickness went down by 21.75 % in 7 eyes. The resultant visual acuity after treatment was improved in 3 eyes, maintained no change in 7 eyes and reduced in 2 eye. The fundus fluorescein angiography in 10 eyes revealed a significant decrease of the leakage in tumor. Postoperative complication of TTT in the 12 eyes included retinal hemorrhage (5 eyes) and retinal fold (1 eye). Conclusion lt;brgt;TTT is an effective treatment for CCH. lt;brgt; lt;brgt;(Chin J Ocul Fundus Dis, 2002, 18: 190-092)
Objective To investigate the therapeutic effects of retinal angioma. Methods The clinical data of 16 cases(20 e yes) were retrospectively analyzed, and the patients included 5 males and 11 females of 23.3 yeras old on average. Four cases in this series affected by bilateral retinal angiomas were identified as von Hippel-Lindou disease. The retinal an giomas were divided into 5 stages according to their degrees of developmnet from simple angiom without vessel dilation to feeder vessel dilation and intraretina l exudates, local retinal detachemnt, massive retinal detachment and complication occurrence in proper order. The methods of treatment were laser photocoagulati on, trans-scleral cryotherapy and vitreoretinal surgery. The patinets were followed up for 37.8 months on average. Results There were 10 eyes (2 in stage 1, 7 in stage 2, 1 in stage 3)treated with laser photocoagulation, and all of the angiomas were controlled after the treatment. The visual acuity im proved in 2 eyes, decreased in 4 eyes, and remained unchanged in 4 eyes. Cryothe r apy was performed on 7 eyes(5 in stage 3, 2 in stage 4). The visual deteriortion was found in 5 eyes; and the state of illness was stable in 3 eyes in stage 3 a nd aggravating in 4 eyes (2 in stage 3, 2 in stage 4). Vitreoretinal surgery was performed on 4 eyes including 2 which had been given photocoagulation, and the visual acuity improved in 2 eyes, decreased in 1 eye, and was unimproved in 1 ey e . The visual acuity decreased to no light perception in an untreated eye after 1.5 year follow-up. New angiomas occurred in 3 eyes with Von Hippel-Lindou disease in the follow-up period. Conclusion Laser photocoagulation is effective in treating the angiomas from stage 1 to 3. Cryotherapy can cause massive exudation and proliferation, and it is only suitable for a few patients in stage 3. The visual prognosis is more favorable in vitreoretinal surgery tha n other therapies for the patients in stage 4. (Chin J Ocul Fundus Dis, 2001,17:296-298)
ObjectiveTo explore the therapeutic effect of transpupillary thermotherapy (TTT) on patient with circumscribed choroidal hemangioma (CCH). MethodsThe clinical data of 16 patients (16 eyes) with circumscribed choroidal hemangioma (CCH) from December 2011 to December 2012, which had been diagnosed by clinical general examination, fundus fluorescein angiography (FFA), and B-scanning ultrasound examination were retrospectively analyzed. The follow-up period was 6-24 months (mean 14 months). ResultsAmong the 8 eyes with peripheral retinal detachment in 16 cases of CCH, the peripheral subretinal fluid was completely absorbed in 6 eyes, and partially absorbed in 2 eyes after TTT. The resultant visual acuity after treatment improved in 12 eyes, and maintained no change in 4 eyes. The results of B-scanning ultrasound examination showed that the thickness of tumor went down in 12 eyes obviously. The results of FFA revealed a significant decrease of the leakage in tumor in all of 16 cases and no complication was observed. ConclusionTTT is an effective therapy for CCH.
