Thanks to the treatment of retinoblastoma (RB) having improved significantly in recent years, there is an increasing trend to use conservative treatment modalities that aim to preserve the globe as well as vision with minimum mortality. RB therapy is a long-term systemic treatment in clinical practice. Although there are many treatment options for RB therapy, such as cryotherapy, photocoagulation, systemic chemotherapy, enucleation and ophthalmic chemotherapy, it is recommended to consider in accordance with the following key points in gaining a reasonable treatment strategies: to make sure that RB is an intraocular period; to determine whether the intraocular RB to be treated with eye preservation or enucleation; what is the case of eye preservation therapy combined with chemotherapy and how to arrange the follow-up of RB patients. It's more complicated to choice the therapeutic measures for RB in clinical practice. So, the patient's condition, economic capability and medical condition should be evaluated comprehensively. The principle of RB treatment should be followed, which is protecting eyeball and visual function without life damage.
Prevention and treatment of infants and young children can avoid blindness, effectively reduce the incidence of children's blindness and vision loss. Eye diseases causing blindness in infants and young children mainly include retinopathy of prematurity, retinoblastoma, familial exudative retinopathy, persistent embryonic blood vessels, vitreous hemorrhage, congenital cataract, etc. Most of them are preventable and controllable, however, many diseases have strict requirements for the effective treatment time window. The basic form and path to carry out the prevention and control of blinding eye diseases in infants and young children are building a prevention and control system with a combination of multi-party medical forces, referral to pediatric eye disease institutions with relevant technical resources for further diagnosis and treatment, so as to achieve early detection, standardized treatment and visual training.
Objective To observe the factors influencing for results of laser treatment of zone one retinopathy of premature（ROP）. Methods The clinical data of 35 patients（69 eyes）with ROP in zone one who diagnosed by examination of indirect ophthalmoscopy were retrospectively analyzed. The eyes were divided into anterior zone one（49 eyes ）and posterior zone one（20 eyes）. The 69 eyes, aggressive posterior ROP（AP-ROP）in 12 eyes, anterior zone one in four eyes and posterior zone one in eight eyes. The laser photocoagulation of diode indirect ophthalmoscopy with +20 D lens and sclera compressor were used to entire avascular retina. Followup ranged from two to 48 months with the mean of (10.85plusmn;11.35 )months. Take the cristae fadeaway and stable condition as cure; retinopathy proceed to the stage 4 and 5 ROP as retinopathy progress. Results Forty-two out of 69 eyes (60.87%) were cured and retinopathy progress in 27 eyes (39.13%). Thirty-four out of 49 eyes (69.38%) with anterior zone one were cured and retinopathy progress in 15 eyes (30.61%); eight out of 20 eyes (40.00%) with posterior zone one were cured and retinopathy progress in 12 eyes (60.00%). The difference of progress rate between anterior and posterior zone one was statistically significant（chi;2=5.15, P＜0.05).Conclusions Laser photocoagulation is effective for treatment of zone one ROP, the prognosis of anterior zone one is better than posterior zone one; retinopathy progress after photocoagulation was associated with extent of fibrovascular organization.
Objective To evaluate the therapeutic effects of treatments of eye-retaining and enucleation for choroidal melanomas. Methods The clinical data of 44 patients (44 eyes) with choroidal melanomas after eye-retaining treatments and enucleation surgery were retrospectively analyzed. The metastasis, retention rate of eyeball after eye-retaining treatment, and visual acuity prognosis were observed and analyzed. In 44 eyes treated by eye-retaining therapy, transpupillary thermotherapy (TTT) was performed primaryly on 7 (15.9%), 106 Ru brachytherapy on 25 (56.8%), and local resection of tumor combined with 106 Ru brachytherapy on 12 (27.3%).The average follow-up period was 13.3 months. Results Forty-four patients had no melanoma metastasis during the follow-up period. In 39 patients (88.6%) who had their eyes retained successfully, the retention rate of eyeball was 100%, 92.9%, and 83.3% in 6, 14, and 24 eyes with small, middle, and large tumor, respectively. In the patients treated by eye-retaining therapy, the visual acuity was ge;0.3 in 11 (28.2%), ge;0.05-＜0.3 in 18 (46.2%), and ＜0.05 (25.6%) in 10 eyes. Conclusions 106 Ru brachytherapy and transpupillary thermotherapy are effective treatments for small and medium-sized choroidal melanomas; some selected cases with large choroidal melanomas was treated with local resection of tumor combined with106 Rubrachytherapy. However, longer followup will be necessary to assess if this treatment has a better comprehensive outcome, compared with enucleation surgery. (Chin J Ocul Fundus Dis, 2006, 22: 150-153)
ObjectiveTo observe the surgical effects of scleral buckling and vitrectomy for familial exudative vitreoretinopathy (FEVR). Methods34 eyes of 27 patients with FEVR who underwent either scleral buckling or vitrectomy were enrolled in this study. There are stage 2B in 2 eyes (5.88%), stage 3B in 7 eyes (20.59%), stage 4A in 1 eye (2.94%), stage 4B in 16 eyes (47.06%), stage 5 in 8 eyes (23.53%). 5 eyes associated with rhegmatogenous retinal detachment. The surgical approaches had been chosen according to the disease stage, severity, extent and morphology of the proliferative membrane. 13 eyes (stage 2B in 2 eyes, 3B in 4 eyes, and 4 in 7 eyes) underwent scleral buckling and 21 eyes (stage 3B in 3 eyes, 4 in 10eyes, and 5 in 8 eyes) underwent vitreoretinal surgery. The main outcome measurement was the anatomic status of the macula, which was recorded as attached, partially attached or remain detached. The mean follow up was (18.00±14.61) months (range 4 to 60 months). ResultsAmong 13 eyes received scleral buckling, the macula was attached in 2 eyes with stage 2B (15.38%), partially attached in 11 eyes (84.62%) including 4 eyes with stage 3B, 1 eye with stage 4A and 6 eyes with stage 4B. Among 21 eyes received vitrectomy, the macula was attached in 8 eyes (38.10%) including 2 eyes with stage 3B, 4 eyes with stage 4 and 2 eyes with stage 5; the macula was partially attached in 9 eyes (42.86%) inducing 4 eyes with stage 4 and 5 eyes with stage 5; the macula remained detached in 4 eyes (19.05%) including 1 eye with stage 3B, 2 eyes with stage 4 and 1 eye with stage 5. ConclusionIf the surgical approaches were chosen based on the stage of FEVR and the severity, extent and morphology of the proliferative membrane, the surgery is effective and beneficial to FEVR patients.
ObjectiveTo observe the clinical effect of small-gauge vitrectomy (SGV) treatment for proliferative diabetic tractional (PDR) with retinal detachment (TRD). MethodsThe data of 42 patients (50 eyes) with PDR combined with TRD who had received SGV treatment were retrospectively analyzed. There were 22 males and 20 females, with an average age of (44.5±11.2) years. There were 16 eyes with TRD involving the macular area, 34 eyes without TRD involving the macular area. The eyes with rhegmatogenous retinal detachment or retinal hole were excluded. The best corrected visual acuity (BCVA) was worse than finger counting in 18 eyes, worse than 0.1 in 15 eyes, 0.1-0.3 in 16 eyes and better than or equal to 0.3 in 1 eye. Post-operative tamponade was delivered for patients with iatrogenic retinal breaks, including 5 eyes with long-acting gas and 7 eyes with silicone oil. The mean follow-up time was 9.7 months. The visual outcome, rate of retinal reattachment and complications were analyzed. ResultsThe visual acuity improved in 34 eyes (68.0%), unchanged in 12 eyes (24.0%) and decreased in 4 eyes (8.0%). The difference of visual acuity before and after surgery was statistically significant (t=7.087, P<0.01).The total rate of retinal reattachment was 96%, and 84% of eyes achieved anatomic reattachment after single surgery. The rate of retinal reattachment was 89.5% (34/38) for these eyes without iatrogenic retinal breaks, 4/38 eyes without iatrogenic retinal breaks still had retinal detachment in 3 months after surgery and received tamponade of long-acting gas or silicone oil. The rate of retinal reattachment was 66.7% (8/12) for these eyes with iatrogenic retinal breaks and received post-operative tamponade. There were 17 eyes experienced postoperative vitreous hemorrhage, which were treated with anti-vascular endothelial growth factor (VEGF) antibodies or vitreous cavity lavage. There were 9 eyes with transient ocular hypertension, and 4 eyes with neovascular glaucoma (NVG). Among 4 eyes with NVG, 2 of which were controlled through anti-VEGF treatment or laser treatment, and 2 eyes of 2 patients refused to have further treatment. ConclusionSGV is safe and effective treatment for PDR combined with TRD, and intraocular tamponade is not necessary in the absence of iatrogenic retinal break.
