Abstract?AlM:To observe thickness and morphological changes of cornea and bulbar conjunctiva pre- and post acute angle closure glaucoma ( AACG ) therapy by optical coherence tomography ( OCT) .?METHODS: Twenty - five patients with AACG were recruited. lntraocular pressure ( lOP ) and morphological characteristic of cornea and conjunctiva were measured at their first visit, 1, 2 and 3d after they began the treatments.?RESULTS:The corneal epithelium thickness and corneal thickness of patients with acute attack of angle closure glaucoma were 72. 76±11. 95μm and 589. 40±66. 91μm; the conjunctival epithelial layer thickness was 58. 88±12. 87μm;the thickness of conjunctive stroma was 299. 76±94. 86μm;the conjunctival full thickness was 358. 64±102. 55μm. The corneal epithelium thickness and corneal thickness at the first day of the treatment were 69. 28±12. 65μm and 579. 04± 67. 88μm;the conjunctival epithelial layer thickness was 57. 04 ± 12. 05μm;the thickness of conjunctive stroma was 282. 44±91. 47μm;the conjunctival full thickness was 339. 48± 100. 28μm. the corneal epithelium thickness and corneal thickness at the second day of treatment were 66. 76 ± 11. 42μm and 563. 32 ± 63. 87μm;the conjunctival epithelial layer thickness was 54. 76 ± 11. 01μm;the thickness of conjunctive stroma was 267. 00 ± 98. 54μm;the conjunctival full thickness was 322. 16 ± 106. 12μm. the corneal epithelium thickness and corneal thickness of the third day treatment are 65. 16 ± 12. 25μm and 550. 36 ± 71. 48μm; the conjunctival epithelial layer thickness was measured 53. 36± 10. 29μm;the thickness of conjunctive stroma was 252. 76± 99. 32μm;the conjunctival full thickness was 306. 52 ± 107. 31μm. The difference of lOP, corneal epithelial thickness, corneal thickness, conjunctival epithelial layer thickness, conjunctival stroma thickness and conjunvtival full thickness had statistically significant(P<0. 05).?CONCLUSlON:The corneal and conjunctival thickness in patients at acute attack of angle closure glaucom increase. The edema level decreases with lOP.
