Clinical features and preliminary report of treatment of vasoproliferative tumors of the retina / 中华眼底病杂志

ABSTRACT

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.
