Retinoblastoma (RB) is the most common intraocular malignancy in childhood. In recent years, with the development of the comprehensive treatment concept based on chemical therapy and the improvement of diagnosis and treatment technology, the long-term survival rate of RB children has been greatly improved, and the treatment goal has gradually shifted from saving the lives of children to improving the quality of life of children. In large RB diagnosis and treatment centers in China, the survival rate of children is basically equivalent to that of developed countries. However, in some backward areas, RB still poses a great threat to the lives of children. Therefore, the necessary measures to improve the survival rate of children with RB and the quality of life of their families are to intensify the popularization of popular science, improve the public awareness of RB disease, improve the diagnostic efficiency, implement reasonable and standardized treatment plans, conduct genetic counseling and prenatal assessment for high-risk groups, and train professional and technical personnel.
ObjectiveTo observe the clinical features, treatment and prognosis of ciliary body tumors. MethodsA retrospective clinical study. From November 2011 to March 2023, 8 cases (8 eyes) with ciliary body tumours confirmed by pathohistological examination at the Department of Ocular Oncology, Beijing Tongren Hospital were included in the study. Patients' age, gender, involved eyes, symptoms, best corrected visual acuity (BCVA), intraocular pressure, cataract, lens subluxation, and imaging manifestations were collected in detail. All affected eyes were treated surgically. The follow-up time after surgery ranged from 1 to 10 years. The patients' clinical presentation as well as imaging, pathohistological features and treatment and prognosis were analysed retrospectively. ResultsAmong 8 cases (8 eyes), there were 3 males (3 eyes) and 5 females (5 eyes), 3 and 5 eyes in the right and left eyes, respectively. The median age was 44 years. Ciliary body medulloepitheliomas, melanoma, squamous cell carcinoma, leiomyoma, schwannoma, and adenoma of the nonpigmcnted ciliary epithelium were in 2, 2, 1, 1, 1, and 1 eyes, respectively. All reported decreased or loss of vision. Cataract, vitreous opacity, red eye and or (ocular pain), retinal detachment, lens subluxation, and secondary glaucoma were 6, 4, 4, 2, 1, and 1 eyes, respectively. Diagnostic imaging was consistent with pathological findings in 3 eyes. The first surgery was performed for enucleation and orbital implantation in 2 eyes, the patients were 9 and 10 years old with medullary epithelioma; the follow-up time after surgery was 1 and 5 years, respectively. Local tumour resection was performed in 6 eyes. Among them, 3 eyes with benign tumours were followed up for 1 to 9 years after surgery; 2 eyes showed significant improvement in visual acuity, 1 eye with adenoma of the nonpigmcnted ciliary epithelium had a preoperative BCVA of finger count/1 m, and a postoperative BCVA of 0.5, and 1 eye with leiomyoma had a preoperative BCVA of 0.06, and a postoperative BCVA of 0.5; and 1 eye was lost to follow-up. Malignant tumour in 3 eyes, of which 2 eyes recurred after surgery. Re-operation for enucleation and local tumour excision combined with local cryotherapy in 2 eyes of recurrence were 1 eye each, respectively. The follow-up period after surgery was 2 and 4 years, respectively. No recurrence after surgery in 1 eye, but there was no significant improvement in visual acuity during follow-up. No recurrence or metastasis was observed in any of the eyes during the follow-up period or at the final follow-up.ConclusionsCiliary body tumour types and clinical presentations are complex and varied; imaging can detect tumours but is poor at determining the nature of the lesion. Benign tumours do well with local excision surgery; malignant tumours do well with enucleation.
