Factors Influencing Visual Acuity Following Vitrectomy for Exudative Age-related Macular Degeneration

Surgical Excision of Type 1 + 2 Choroidal Neovascularization in Age-Related Macular Degeneration

“…In 2000, we reported that CNV excision achieved improvement of final visual acuity in 56% of AMD cases if the CNV was located mainly above the RPE. 5 However, these cases included both type 2 and type 1 + 2 cases.…”

Surgical excision of neovascularization in retinal angiomatous proliferation

“…Caution was exercised during surgery to avoid macular hole formation. Then, the neovascular membrane was removed with forceps (Dorc) below the [8,10]. Fluid-air exchange was conducted in five eyes and fluid-gas (SF6) exchange in four eyes.…”

Preoperative Factors Influencing Visual Outcome following Surgical Excision of Subfoveal Choroidal Neovascularization in Age-Related Macular Degeneration

“…A retinotomy was performed; the CNV was separated fro m the sensory retina and RPE using a spatula (Dorc, VN Zuidland, The Netherlands) under high perfusion pre s s u re . Then, the CNV was excised using subretinal horizontal forceps (Dorc), and fluid-air exchange was conducted (1,4).…”

“…In patients with age-related macular degeneration (AR-MD), various modalities have been used to treat subfoveal c h o roidal neovascularization (CNV), including surgical CNV excision (1)(2)(3)(4)(5)(6), macular translocation, photodynamic therapy (PDT), intravitreal triamcinolone, intravitreal antivascular endothelial growth factor, and transpupillary thermotherapy (7)(8)(9)(10). Surgical CNV excision causes some degree of defect in the retinal pigment epithelium (RPE), and formation of central scotoma as well as difficulty in achieving significant visual improvement are problems associated with this p ro c e d u re (1,4).…”

“…In 1994, Thomas et al (1) conducted CNV excision in 41 eyes with ARMD and reported no change in visual acuity in 73%. In 2000, we proposed that if cases with CNV located mainly above the RPE are selected, CNV excision will result in minimal RPE defects and greater impro v ement of visual acuity (4).…”
