ABSTRACT
PURPOSE: To assess the efficacy and safety of combined intracameral sulfur hexafluoride and full-thickness corneal sutures in the treatment of acute corneal hydrops (CH). METHODS: This is an uncontrolled series of cases with keratoconus (KC), keratoglobus (KG), and pellucid marginal degeneration that presented with CH of recent onset. RESULT: Thirteen patients completed the study. The mean corneal thickness before treatment was 1,310 (Equation is included in full-text article.)556 µm, which significantly reduced to 660 ± 148 µm at week 1 postoperatively (P = 0.001). It took 11.5 ± 6.5 days for corneal edema to resolve with a minimum and maximum of 5 and 24 days, respectively. Corrected distance Snellen visual acuity (CDVA) significantly improved from 0.04 ± 0.03 before treatment to 0.08 ± 0.06 at week 1 (P = 0.035) and continued to improve through month 1 [(0.11 ± 0.05), P = 0.007] and month 3 [(0.15 ± 0.08), P = 0.002]. No patient needed re-treatment with gas injection, and no complication was detected during the follow-up period. CONCLUSIONS: Combined intracameral gas injection and approximation sutures are probably effective and safe for the treatment of acute CH. This treatment results in rapid recovery with very rare complications.
