要約 緒言:オミデネパグイソプロピル(OMDI)点眼で角膜乱視度数,角膜高次収差が変化した兄妹例を経験したので報告する。
症例1:22歳,男性。目のかすみを主訴に受診した。視力は両眼(1.2),眼圧は右26mmHg,左28mmHgであった。右眼にOMDI点眼を開始したところ,視力低下を自覚した。右眼圧は11mmHgで,視力は(1.2)であったが,角膜乱視度数が−0.25Dから−1.0Dと増強,角膜高次収差も大きくなっていた。左眼にOMDI点眼開始後,右眼と同様の変化を認め,両眼とも角膜厚が増大していた。
症例2:19歳,女性(症例1の妹)。眼鏡処方を希望して受診した。視力は右(1.5),左(1.2),眼圧は右28mmHg,左30mmHgであった。両眼にOMDI点眼を開始。1か月後,眼圧は両眼とも12mmHgと下降したが,角膜乱視度数は増強,角膜高次収差も大きくなった。充血にて点眼自己中止し再診した。眼圧は再上昇し,角膜乱視度数や角膜高次収差は軽減していたが残存していた。角膜厚は増大していた。
結論:OMDIによる著明な眼圧下降と角膜乱視度数や角膜高次収差,角膜厚が変化した兄妹例を経験した。OMDI点眼開始後の見えにくさに角膜肥厚による角膜乱視や角膜高次収差の変化が関与している可能性がある。
Abstract Purpose:We report a sibling case of corneal astigmatism and corneal higher order aberrations treated with omidenepag isopropyl(OMDI)eye drops.
Case 1:22-year-old male. He visited Nagata eye clinic due to blurred vision. His best correct visual acuity was 1.2 in both eyes and intraocular pressure(IOP)was 26 mmHg in the right eye(RE)and 28 mmHg in the left eye(LE). After starting OMDI eye drops in the RE, he felt the visual acuity of the right eye decreased. At the next visit, the RE IOP was 11 mmHg and visual acuity was(1.2), but the corneal astigmatism increased from −0.25D to −1.0D and the corneal higher order aberration was also increased. When OMDI were started in the LE, the same changes were observed, and the corneal thickness increased in both eyes.
Case 2:19-year-old younger sister of the patient described in Case 1 visited our clinic for fitting glass. Her best correct visual acuity was(1.5)in the RE,(1.2)in the LE. IOP was 28 mmHg in the RE, 30 mmHg in the LE, and OMDI were started in both eyes. After 2 weeks, the IOP decreased to 12 mmHg in both eyes, with increase in corneal astigmatism increased and corneal higher order aberration. She stopped self-administration of OMDI due to hyperemia for a week and visited the clinic three months after starting OMDI. The IOP increased again, and the corneal astigmatism and higher-order aberration persisted despite some reduction. The corneal thickness increased in both eyes.
Conclusion:We encountered a case of sibling with remarkable IOP reduction and changes in corneal astigmatism and corneal higher-order aberrations, and increase in corneal thickness on administration of OMDI. Increasing corneal thickness with OMDI may be related to visual disorder of corneal astigmatism, corneal higher-order aberrations.
