Efficacy and Safety of Sub-tenon Ranibizumab for Recurrent Pterygia
The Use of Ranibizumab to Control Pterygium Growth in Recurrences and in Non-surgical Primary Lesions.
Ranibizumab, an effective antineovascular drug, will be studied for safety and efficacy in pterygium, a neovascular disorder of the ocular surface.

Ptergyia are chronic fibrovascular lesions of the ocular surface. This study is designed to look for a signal of efficacy when the lesions are in a phase of active vascular growth. This phase is most often caught in a newly recurring pterygia post-operatively.

Patients identified with actively growing lesions, will be offered local injections directly beneath the lesions. They will be examined for any adverse side effects and regression of the lesion.

Phase 1
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Drug: Ranibizumab
Subtenon injections of Ranibizumab 0.5mg will be given, and repeated twice with 30 day intervals between each dose. Note, after an amendment in February 2011, this dose was increased to 2mg with the same schedule.
Experimental: Ranibizumab treatment
Patients will receive a sub-tenons injection of Ranibizumab 0.5mg, to be repeated twice with 30 day intervals between each dose.
Intervention: Drug: Ranibizumab
