Indocyanine green dye enhanced laser photocoagulation for juxtafoveal choroidal neovascularisation.

PURPOSE: To evaluate the initial results of pilot study of indocyanine green dye enhanced laser photocoagulation for juxtafoveal choroidal neovascularisation (CNV). MATERIALS AND METHODS: The study was conducted on eleven eyes of 11 patients of CNV during the period 2001 and 2002. Two to three minutes after the injection of 5 ml of 25 mgm of indocyanine green (ICG) dye, 810 nm diode laser was used to treat the choroidal neovascular lesions. RESULTS: The age of the patients ranged from 45 to 80 years. All patients completed 12 months of follow-up. Eight eyes (72.7%) had neovascular age related macular degeneration, 2 eyes (18.2%) had myopic CNV and one eye (9.09%) had CNV secondary to angioid streak. The presenting visual acuity was <or=6/60 in seven, 6/36 in one and >or=6/12 in three patients. The final visual acuity at the end of at least 12 months follow-up was 6/12 or better in one eye (9%); 6/18-6/36 in 3 eyes (27.27%) and <or=6/60 in 7 eyes (63.64%). In four patients the vision improved whereas it worsened or remained same in 7 eyes. CONCLUSION: ICG dye enhanced diode laser photocoagulation appears to be a potential option for juxtafoveal CNV.

Role of photodynamic therapy in polypoidal choroidal vasculopathy.

PURPOSE: To evaluate photodynamic Therapy (PDT) with Verteporfin for polypoidal choroidal vasculopathy (PCV) involving the fovea in Indian eyes, through a retrospective interventional case series. MATERIALS AND METHODS: We retrospectively reviewed the records of 9 patients (9 eyes) diagnosed to have PCV with foveal involvement between September 2001 and October 2002. RESULTS: Nine eyes underwent PDT for PCV. Follow-up ranged from 12 to 16 months. Initial visual acuity (VA) ranged from 1/60 to 6/12 and final VA varied from 1/60 to 6/9 at the end of follow-up. VA improved in 4/9 eyes (44.4%) by one line and remained unchanged in 5/9 eyes (55.6%), hence it was considered stabilized in all eyes. No adverse effects or events were observed during or after treatment with verteporfin. CONCLUSION: PDT may be beneficial for PCV with foveal involvement. Its long-term efficacy requires to be evaluated.

PFCL and ILM peeling in macular hole with retinal detachment / 国际眼科杂志(Guoji Yanke Zazhi)

● AIM: To demonstrate the operative technique and surgical outcome of using perfluorocarbon liquids (PFCL) in internal limiting membrane (ILM) peeling of eyes with macular hole associated with retinal detachment.● METHODS: The study consists of 8 consecutive eyes of 8 patients diagnosed to have total retinal detachment (RD) with macular hole between December 2001 and October 2002.The age ranged from 13 to 65 years (mean 39 years). The male female ratio was 5:3. Four eyes were in Non-myopic Group and 4 eyes in Myopic Group. The patients underwent vitrectomy, ICG dye to stain the ILM,PFCL to flatten the retina intraoperatively, ILM peeling,fluid air exchange and endolaser was performed around the peripheral breaks. Tamponade with either silicone oil or C3F8was used.● RESULTS: The follow-up ranged from 6 to 9mo (mean 6.5mo). In Non-myopic Group. Macular hole was completely closed at the end of follow-up in 3 eyes (75%)and decreased size with flat edge in 1 eye (25%). In Myopic Group. All 4 eyes had successful closure of macular hole at the end of the follow-up. Comparing the groups,complete closure of macular hole was achieved in 7 eyes (88%) and open hole with flat edge was seen in 1 eye (12%) at the end of follow-up.● CONCLUSION: Using PFCL is helpful in the peeling of ILM for macular hole associated with retinal detachment.

Optical coherence tomographic evaluation of foveal pseudocyst in the formation of macular hole.

Optical coherence tomographic documented progression of foveal pseudocyst in a vitrectomised eye to full thickness macular hole is reported. Muller cell alteration and other centrifugal forces are possible pathomechanisms.
