INTRODUCTIONTo report the sequential changes in corneal topography and astigmatism following limited macular translocation. CLINICAL PICTURE AND TREATMENT: A 45-year-old-man who underwent limited macular translocation for idiopathic subfoveal choroidal neovascularisation in the right eye was evaluated by corneal topography and manifest refraction preoperatively and serially for 1 year postoperatively.
OUTCOMEAn increase in astigmatism with corneal steepening along meridians corresponding to the area of chorioscleral infolding was observed and this persisted for 1 year after surgery. Vector-analysed astigmatic change showed significant surgically induced astigmatism of 2.18 dioptres (D) X 52.9 degrees, 2.17 D X 57.8 degrees and 2.56 D X 59.1 degrees at 2, 5 and 12 months after surgery respectively.
CONCLUSIONSurgically induced corneal changes are evident after limited macular translocation and may remain up to 1 year after surgery.

The visual results of laser photocoagulation for subfoveal choroidal neovascular membrane (CNVM) has not always been satisfactory. The surgical removal of the neovascular membrane may be another treatment option. To investigate the prognosis and risk factors of this surgery, we analyzed the results of surgical removal of subfoveal CNVM (23 eyes), subfoveal hemorrhage with CNVM (6 eyes), and subfoveal hemorrhage alone (6 eyes). The mean follow-up period was 17.7 months (range 2 to 47 months). The mean preoperative membrane size was 0.89 disc diameter and the mean postoperative retinal pigment epithelial (RPE) defect size was 1.33 disc diameter. Visual improvement was observed in 13 out of the 23 eyes (56.5%) with sufoveal CNVM, four out of the six eyes (66.6%) with subretinal hemorrhage and CNVM, and five out of the six eyes (83.3%) with subretinal hemorrhage only. The visual outcome of subfoveal CNVM surgery was related to the presence of a subfoveal RPE defect (p = 0.005) rather than to the size of the RPE defect. No recurrence of neovascular membrane was observed during the follow up period. In conclusion, surgical removal may be a good alternative treatment for subfoveal CNVM.

Little is known about the natural history and management of choroidal neovascularization (CNV) which developed as a complication of laser photocoagulation for central serous chorioretinopathy (CSC). We experienced two patients with CNV which developed after laser treatment for CSC. Submacular membranectomy was performed on both cases after the confirmation of subretinal CNV with optical coherence tomography. One patient received photodynamic therapy for recurrent CNV. The vision of both patients has been improved over 6 months of follow up. These cases suggest that active intervention, including submacular surgery, improves the visual prognosis of this condition.

BACKGROUNDPolypoidal choroidal vasculopathy (PCV) is characterized by the presence of polyps with or without a branching vascular network and more prevalent among Asians. The aim of this study was to compare the outcomes of conbercept therapy between two different angiographic subtypes of PCV.
METHODSFifty-eight patients of PCV were classified into two phenotypes according to indocyanine green angiography (ICGA). In Type 1, both feeder and draining vessels are visible on ICGA and network vessels are numerous. In Type 2, neither feeder nor draining vessels are detectable, and the number of network vessels is small. The patients were treated with intravitreal conbercept (IVC) for 3 months. Additional IVC was given at subsequent monthly visits, if needed. The patients were followed up for 12 months, and changes in mean best-corrected visual acuity (BCVA), central retinal thickness (CRT), subretinal fluid (SRF) thickness, pigmented epithelial detachment (PED), hemorrhage, and number of polypoidal lesions were evaluated.
RESULTSThe mean BCVA in Type 2 PCV (15.92 ± 9.76 letters) achieved a significantly greater improvement than that in the Type 1 (14.10 ± 9.07 letters) at month 12 (t = 2.37, P< 0.01). Moreover, the mean CRT decrease was numerically greater in Type 2 (120.44 ± 73.81 μm) compared with Type 1 (106.48 ± 72.33 μm) at month 6 (t = 4.31, P< 0.01), and greater in Type 2 (130.21 ± 76.28 μm) compared with Type 1 (111.67 ± 79.57 μm) at month 9 (t = 1.87, P< 0.01). There was no significant difference between the two types for the decrease in SRF thickness, PED height, and regression of polyps from month 3 to 12 (t = 2.97, P > 0.05).
CONCLUSIONClassification systems for PCV will show differences in presentation, natural history, or response to anti-vascular endothelial growth factor treatment and might, therefore, provide a new key to the choice of treatment for the disease.

We report a case of recurrent choroidal neovascularization (CNV) in an eye with chorioretinal coloboma. A 36-year-old woman presented complaining of decreased visual acuity (VA) in her left eye. Best corrected visual acuity (BCVA) was 20/200 and iris coloboma was observed. Funduscopy and fluorescein angiography (FA) showed CNV in the superior extrafoveal region with chorioretinal coloboma reaching just inferior to the optic disc. No other cause for CNV was observed except for the chorioretinal coloboma. BCVA improved to 20/30 after laser photocoagulation. She revisited our clinic for deteriorating VA (20/400) in the same eye 3 years after treatment. Funduscopy and FA demonstrated recurrent CNV with subfoveal hemorrhage. Photodynamic therapy (PDT) was followed by three consecutive intravitreal bevacizumab injections (IVB) for the subfoveally-located CNV. However, the CNV persisted with the appearance of a fresh subretinal hemorrhage. Additional PDT was combined with IVB on the same day 6 months after the initial PDT. The CNV regressed 3 months after treatment and has not recurred as of 8 months after the last treatment. The patient's BCVA improved to 20/60. This case suggests that PDT combined with IVB can be an alternative treatment for the management of recurrent CNV after laser photocoagulation in eyes with chorioretinal coloboma.

7.Initial experience of macular translocation in Singapore - one-year results.
Annals of the Academy of Medicine, Singapore 2004;33(5):641-648
INTRODUCTIONThis paper reports the 1-year results of the first 2 cases of macular translocation in Singapore.
CLINICAL PICTUREA 66-year-old female and a 45-year-old male Chinese presented with subfoveal choroidal neovascularisation (CNV) in their right eyes. The woman's condition was secondary to pathological myopia while the man's was idiopathic. Their preoperative best-corrected visual acuities were 6/15-2 and 6/30, respectively.
TREATMENTBoth patients underwent macular translocation with punctate retinotomies and chorioscleral infolding (limited macular translocation) in their affected eye.
OUTCOMEBoth patients achieved effective macular translocation postoperatively. Their CNVs became extrafoveal and were ablated with conventional laser photocoagulation in the early postoperative period. They did not recur and their visual acuities improved to 6/9-1 and 6/12 at 1 year postoperatively, respectively.
CONCLUSIONMacular translocation is a new treatment modality that offers patients with subfoveal CNV a chance of improving their vision, potentially to a level that may allow reading and driving.
