Peripheral retinal neovascularization in recurrent cicatricial toxoplasmic retinochoroiditis: Case series report

Purpose: To report cases of retinal neovascularization in association with cicatricial plaques of congenital recurrent toxoplasmic retinochoroiditis. Methods: This was a retrospective review of retinologist records. Four cases found were documented with diagnostic techniques, mainly fluorescein angiography, optical coherence tomography and laboratory confirmation. Management included focal laser photocoagulation and pars plana vitrectomy. Results: In 4 cases, one presented spontaneous involution of neovascularization and vitreous hemorrhage. Three cases of neovascularization responded to laser photocoagulation and 2 cases to pars plana vitrectomy. Three cases regained 20/25 vision. Conclusions: Peripheral neovascularization associated with plaques of cicatricial toxoplasmic retinochoroiditis has been rarely reported. Therefore, a routine careful examination of fundus periphery is recommended.
