PURPOSE: To evaluate clinical characteristics and the macular gradient in myopic posterior staphyloma with time domain (TD) optical coherence tomography (OCT). METHODS: Sixty-four staphyloma eyes of 40 patients were examined. Macular gradient (tangent theta) and the location of staphyloma were assessed with OCT imaging. The macular gradient was measured at points 1 mm and 2 mm distant from the fovea. The relationships of the macular gradient with age, axial length, and spherical equivalent were analyzed. RESULTS: In 8 eyes (12.5%), the bottoms of the staphylomas were in the fovea, and there was no macular gradient. However, in the other 56 eyes (87.5%), the bottoms of the staphylomas were not in the foveal area, and macular gradients existed. Staphylomas were commonly located in the infero-nasal retinal area. The mean macular gradient (tangent theta) was 0.26 +/- 0.08 at 1 mm distance from the fovea and 0.28 +/- 0.10 at 2 mm. No significant relationships were observed between macular gradient and axial length, patient age, or spherical equivalent. CONCLUSIONS: TD OCT reveals staphyloma location. If the location is outside of the fovea, a macular gradient exists and can be measured by OCT. Axial length measurement error may occur in eyes with poor visual fixation and steep macular gradients.

The purpose of this study was to evaluate the anatomical outcomes of vitrectomy with internal limiting membrane removal in highly myopic eyes with retinal detachment caused by a macular hole. Nineteen, consecutive, highly myopic eyes with full thickness macular hole with retinal detachment were treated by vitrectomy with internal limiting membrane removal, endolaser photocoagulation on the center of the hole and fluid gas exchange. In five eyes with other peripheral breaks, scleral buckling (3 cases), encircling (1 case) and barrier laser (1 case) were combined. In 15 eyes (79.0%) the macular hole was closed after the initial surgery. In 4 eyes (21%) the macular hole was reopened, but these were successfully treated with fluid gas exchange (1 case) or macular buckling (3 cases). The visual acuity was improved in 15 eyes (79.0%). In conclusion, these results suggest that the removal of the perifoveal internal limiting membrane may be an important adjuvant in the treatment of the myopic macular hole with retinal detachment.

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.

BACKGROUNDPathological myopia (PM) is the leading cause for choroidal neovascularization (CNV) in people below 50 years of age, the anti-vascular endothlial growth factor (VEGF) medicine is now available to treat CNV secondary to PM. This study aimed to observe the efficacy of intravitreal ranibizumab for PM associated with subfoveal or juxtafoveal CNV in Chinese patients.

METHODSFifty-four eyes of 52 consecutive patients were included, they treated with intravitreal ranibizumab 0.5 mg for PM associated with CNV. The best corrected visual acuity (BCVA) of Snellen chart, letters of ETDRS chart, retinal thickness, leakage of CNV lesion, and complications with surgery were analyzed pre- and post-treatment. Eligibility criteria included diopter ≥-8.0 D or eye axis ≥ 28 mm with fundus changes of PM (lacquer crack, optic disc atrophy, chorioretinal atrophy, posterior scleral staphyloma); CNV secondary to PM; subfoveal or juxtafoveal CNV.

RESULTSFor 54 affected eyes of 52 consecutive patients, the average BCVA of Snellen chart and letters of ETDRS chart were 0.29 and 30.4, respectively; fundus fluorescein angiography (FFA)/indocyanine green angiography (ICGA) showed CNV leakage, and average retinal thickness on optical coherence tomography (OCT) was 267.2 µm before treatment. Injections of ranibizumab ranged from 1 to 4 (mean 2.2). Follow-up time varied from 12 to 36 months (mean 31.9 months). At the last visit, the BCVA of Snellen chart was increased by three lines (mean 0.65) (P < 0.01); the letters of ETDRS chart were increased to 17.0 letters (mean 47.4, P < 0.01); the visual acuity increased more than 15 letters in 30 eyes (55.5%), decreased in 1 eye (1.9%); the retinal thickness on OCT images was decreased by 17.0 µm (mean 250.2 µm) (P = 0.082); no active leakage from the CNV lesion occurred in 18 eyes (33.3%), reduced leakage in 30 eyes (55.6%), and no change in 6 eyes (11.1%) as shown by FFA/ICGA. Increased retinoschisis was observed in one eye after the second injection.

CONCLUSIONSIntravitreal ranibizumab for neovascular PM was well tolerated in Chinese patients, with functional and anatomic improvements in a short-term study, while a long-term study is still needed.
