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 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.

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.
ObjectiveTo observe the effectiveness of radiotherapy for refractory choroidal hemangioma. MethodsEight patients (8 eyes) with choroidal hemangioma were enrolled in this retrospective study. All the patients had received laser or photodynamic therapy before without effectiveness. The patients included 7 males and 1 females. The age was ranged from 11 to 54 years old, with an average of (27.50±15.18) years. All the patients were affected unilaterally, including 3 right eyes and 5 left eyes. There were 5 eyes with circumscribed choroidal hemangioma, 3 eyes with diffused choroidal hemangioma. All eyes had extensively exudative retinal detachment. The vision was from light sensation to 0.01. The volume of the tumors was ranged from 1.96 to 5.35 cm3, with a mean of (3.37±1.06) cm3. All the patients were treated with X rays by conventional fractional radiotherapy. Four of 8 patients were applied 24Gy totally in 8 fractions, while the other 4 patients were applied 46Gy in 23 fractions. Follow-up period ranged from 7 to 95 months, with medium of 42 months. ResultsRetinas reattached in all the eyes while exudation being absorbed. No retinal detachment happened again. To the last follow-up, the vision was from light sensation to 0.6. Visual activity improved in 6 eyes while 2 eyes improved obviously. Visual acuity was stable in remaining 2 eyes. The volume of the tumors decreased to 1.24-2.16 cm3, with a mean of (1.68±0.30) cm3. The percentage of the tumor decreased by 14.6-72.7, with an average of (44.89±21.30)%. No radiotherapy-associated complication occurred. ConclusionRadiotherapy is an efficient and safe treatment for refractory choroidal hemangioma.
ObjectiveTo observe the clinical effect of prolonged photodynamic therapy (PDT) irradiation time combined with intravitreal injection of ranibizumab in the treatment of circumscribed choroidal hemangioma (CCH).MethodsA retrospective clinical study. From March 2012 to March 2018, 51 eyes of 51 patients diagnosed in Shenzhen Eye Hospital were included in the study. Among the patients, the tumor of 36 eyes were located in macular area, of 15 eyes were located outside macular area (near center or around optic disc). All patients underwent BCVA, color fundus photography, FFA, ocular B-scan ultrasonography and OCT examinations. The BCVA examination was performed using the international standard visual acuity chart, which was converted into logMAR visual acuity. OCT showed 48 eyes with macular serous retinal detachment. of 36 eyes with tumor located in macular area, the logMAR BCVA was 0.05±0.05, the tumor thickness was 4.5±2.2 mm, the diameter of tumor was 9.7±3.6 mm. Of 15 eyes with tumor located outside macular area, the logMAR BCVA was 0.32±0.15, the tumor thickness was 3.8±1.4 mm, the diameter of tumor was 7.7±1.9 mm. PDT was performed for all eyes with the irradiation time of 123 s. After 48 h, all patients received intravitreal injections of 0.5 mg ranibizumab (0.05 ml). At 1, 3 and 6 months after treatment, the same equipment and methods before treatment were used for related examination. BCVA, subretinal effusion (SRF), tumor leakage and size changes were observed. BCVA, tumor thickness and diameter before and after treatment were compared by t test.ResultsAt 6 months after treatment, the tumor was becoming smaller without scar formation. FFA showed that the blood vessels in the tumor were sparse compared with those before treatment, and the fluorescence leakage domain was reduced. OCT showed 43 eyes of macular serous detachment were treated after the combined treatment. The logMAR BCVA were 0.16±0.15 and 0.55±0.21 of the eyes with tumor located in or outside macular area, respectively. The difference of logMAR BCVA between before and after treatment was significant (t=－2.511, －2.676; P=0.036, 0.040). Both the tumor thickness (t=3.416, 3.055; P=0.011, 0.028) and diameter (t=4.385, 4.171; P=0.002, 0.009) of CCH patients were significantly reduced compared with that before treatment.ConclusionThe tumor of CCH can be reduced by prolonged PDT irradiation time combined with intravitreal injection of ranibizumab.
