Purpose: To report the effect of intravitreal bevacizumab in type 2 idiopathic macular telangiectasia (type 2 IMT).
Design: Interventional case report.
Methods: A 51 year-old female patient with type 2 IMT presented with gradual visual deterioration and reading difficulties. In one affected eye, two intravitreal bevacizumab injections were performed with a four weeks interval. Examinations included ETDRS visual acuity, slit-lamp biomicroscopy, digital fluorescein angiography, optical coherence tomography (OCT) and microperimetry at baseline and during a 12-week review period.
Results: Following treatment the patient noted a visual improvement particularly during reading. On angiography a reduction in size and intensity of the hyperfluorescent area was recorded and the retinal sensitivity improved on microperimetry.
Conclusions: In absence of other efficacious therapeutic modalities, the observations indicate a beneficial therapeutic effect of intravitreal bevacizumab in type2-IMT, and implicate a pathophysiological role of VEGF in this disease entity.

Bleb-like retinal detachment (BLRD) in posterior zone 1 retinopathy of prematurity (ROP) presents a significant therapeutic challenge and is associated with a guarded visual prognosis. We present a case of a female infant born preterm with a birth weight of 1100 g. Examination revealed bilateral stage 4 aggressive ROP in posterior zone 1 with BLRD.

Purpose: Laser photocoagulation (LPC) has been a traditional treatment for retinopathy of prematurity (ROP). However, intravitreal anti-VEGF agents such as bevacizumab and ranibizumab (IVR) have also been increasingly used. This meta-analysis aims to rigorously compare IVR to LPC in the treatment of ROP.

Intravitreal melatonin for the prevention of radiation retinopathy: a step beyond bevacizumab.
Int J Radiat Biol
January 2025
Department of Radiation Oncology, Faculty of Medicine, Hacettepe University, Ankara, Turkey.
Purpose: Intravitreal bevacizumab has been utilized to mitigate radiation retinopathy, yet the potential role of intravitreal melatonin for its prevention remains unexplored. This study aims to evaluate and compare the efficacy of intravitreal melatonin and bevacizumab in preventing radiation retinopathy in an experimental animal model.
