Abstract. Purpose:To report characteristic fundus manifestations of superior segmental optic hypoplasia. Cases and Methods:This retrospective study was made on 66 eyes of 40 cases who were diagnosed with superior segmental optic hypoplasia. The series comprised 16 males and 24 females. The condition was bilateral in 26 cases and unilateral in 14. The age ranged from 4 to 68 years,average 43 years. Results:All cases had good visual acuity and inferior altitudinal field defect. The optic disc was topless in 7 eyes(11%)and superiorly hypoplastic in 59(89%). There was a high incidence of attenuation of retinal nerve fiber layer(RNFL)in the superior segment and superior location of central retinal artery at its entrance. There was no disc hemorrhage or peripapillary chorioretinal atrophy. Conclusion:Superiorly hypoplastic disc is frequent in superior segmental optic hypoplasia. Its diagnosis may be facilitated by noting the thinning of RNFL in the superior segment and dislocation of site of entrance of central retinal artery.
