目的　试用焦点激光治疗黄斑水肿 ,以挽救和保存患眼视力。方法　黄斑水肿患者45例 ,以眼底荧光血管造影进行分类 ,对局限性黄斑水肿直接光凝渗漏点 ,而弥漫性黄斑水肿则用格栅状光凝法 ,距黄斑中心凹 5 0 0μm以外光凝 ,共光凝 2～ 3排。结果　经 3mo～ 3a的观察 :(1)视力 :保持原有视力者 35例 (43只眼 ) ,占 78% ;提高 2行以上者 8例占 18% ;下降2行以下者 2例占 4% ;(2 )黄斑水肿消退情况 :32例 (71% ) 3～ 6 mo黄斑渗漏消失 ,水肿完全吸收 ;11例 (2 5 % )水肿大部分吸收 ;2例 (4% )黄斑渗漏仍存在 ,原有水肿无明显吸收。结论　焦点激光光凝是治疗黄斑水肿的有效方法之一 ,只要选择好病例 ,注意掌握好使用技术 ,可达到消除水肿 ,保存视力的目的。 Objective To test the focus of laser treatment of macular edema, to save and save the affected eyesight. Methods Forty-five patients with macular edema were classified by fundus fluorescein angiography, and were directly photocoagulated on the macular edema. The diffuse macular edema was treated by the grid photocoagulation, which was away from the foveal of the macula Condensation, a total of 2 ~ 3 row of photocoagulation. Results After 3mo ~ 3a observation: (1) visual acuity: maintain original vision in 35 cases (43 eyes), accounting for 78%; improve more than 2 lines in 8 cases accounted for 18%; down 2 lines below 2 cases accounted for 4 (2) The regression of macular edema: macular edema completely disappeared in 32 cases (71%) 3 to 6 months, edema was completely absorbed in 11 cases (25%), and macular leakage in 2 cases (4%) Still exist, the original edema no obvious absorption. Conclusions Focus laser photocoagulation is one of the effective methods for the treatment of macular edema. So long as choose a good case and pay attention to mastering the technique, it can achieve the goal of eliminating edema and preserving eyesight.
