白内障手術既往のあるロービジョン患者の近見用視覚補助具処方状況

Current status of optic aids for near vision prescribed to low-vision persons with previous cataract surgery

要約　目的：白内障手術後ロービジョン患者の近見用視覚補助具処方の状況の報告。対象と方法：両眼白内障手術既往があり，ロービジョンケアを受けた62例。良いほうの眼の視力，屈折値，近見用視覚補助具処方状況について調査した。結果：対象の内訳は，近見用視覚補助具処方あり群は32.3％，処方なし群は67.7％であった。両群ともに原疾患は，網膜色素変性症が最多であった。年齢，術後屈折値に両群間で有意差があった。視力には両群間で有意差はなかった。結論：術後屈折値がより遠視寄りの患者で近見用視覚補助具が処方され，高齢でより低視力の患者で処方されていなかった。

Abstract.　Purpose：To report the current status of optic aids for near vision prescribed to low-vision persons with previous cataract surgery. Cases and Methods：This survey was made on 62 persons who had cataract surgery and who received low-vision care. They were analyzed regarding visual acuity in the better-seeing eye, refraction, and prescription of optic aids for near vision. Results：Twenty persons（32.3％）had received prescription of optic aids for near visison. The other forty-two（67.7％）had not. Retinitis pigmentosa was the leading cause of poor vision in both groups. Significant differences were present between the two groups regarding age and refraction. No significant difference was present between the two groups regarding visual acuity. Conclusion：There was a tendency for optic aids to be prescribed in persons with hyperopia. Persons in more advanced age and with poorer vision tended not to receive optic aids.
