Post traumatic endophthalmitis is an uncommon but severe complication of ocular trauma. We aimed to identify the incidence of post traumatic endophthalmitis and its contributing risk factors in Feiz hospital (Isfahan, Iran) from 2006 until 2010. Medical records of 1042 patients with open globe injury were analyzed and data were collected including age, sex, location of being injured, visual acuity (VA), time from injury to hospitalization and to repair, site of ophthalmic injury and the presence of foreign body. The frequency of post-traumatic endophthalmitis was about 2.1% (N = 22) of all patients. Nine of 22 cases with endophthalmitis were under 8 years. The visual acuity at the time of admission was seen to be contributed to high rate of endophthalmitis. Intraocular foreign body was detected in 139 patients; and the rate of endophthalmitis was 5% among these patients. Statistical analysis showed significant relationship between presence of foreign body and higher rate of endophthalmitis. Also, duration of hospitalization was significantly different between two study groups (P = 0.019). There were no significant differences between two groups in terms of other studied variables. Patients with low age, low visual acuity at admission, presence of intraocular foreign body and long duration of hospital stay had a higher risk of endophthalmitis after the repair of the globe. Compared to the reports of other large institutions, we can attribute the low incidence rate of endophthalmitis in our institution to the early use of systemic antibiotics such as gentamycin and cephalosporins in the first hour of hospitalization until discharge.

Background:To report the long-term findings of corneal cross-linking (CXL) with riboflavin drops on the corneal endothelial cell.Materials and Methods:In this prospective non-randomized study, we aim to assess the long-term safety of CXL on the corneal endothelium for the treatment of progressive keratoconus, by endothelial specular microscopy. A total of 68 eyes of 42 keratoconus patients were selected. We checked the corneal thickness (with ultrasonic pachymetry), endothelial cell density, pleomorphism, and polymegathism (with specular microscopy) of the endothelial cells, before CXL and one year after this procedure.Results:The mean ± SD of the preoperative and postoperative corneal thicknesses were 470 ± 40 μm and 469.8 ± 42 μm, respectively (p-value = 0.591). The mean ± SD of the preoperative and postoperative endothelial cell densities were 2753 ± 230 cells/mm[2] and 2699 ± 210 cells/mm,[2] respectively (p-value = 0.004). We found reduction in the endothelial cell density after CXL, but this reduction was less significant in a corneal thickness of less than 400 μm (which was treated with hypo-osmolar riboflavin 0.1% drops) compared to the corneal thickness of more than 450 μm. We did not find any significant differences in the cell shapes (pleomorphism) (p-value = 0.517), but the cell sizes (polymegathism) were changed after the procedure (p-value = 0.021).Conclusion:We found a significant decrease in endothelial corneal cell density after CXL, but this reduction was low; also the size of these cells increased after CXL. We believe that other parameters besides the corneal thickness may be the determinant factors for the changing of cell density and cell size in corneal endothelial cells.

Background:Adjustable suture used for years to improve the outcome of strabismus surgery. We surveyed outcome of our patients with strabismus who underwent adjustable suture.Materials and Methods:This retrospective study was performed at Ophthalmology Centre of Feiz Hospital in Isfahan on 95 participants that candidate for adjustable suture strabismus surgery. Patients were divided into three age groups: Under 10 years, 10-19 years, and 20 years and over. Outcome of adjustable suture surgery consequence of residual postoperative deviation was divided into four groups: Excellent, good, acceptable, and unacceptable.Results:Out of 95 patients studied, 51 (53.7%) were males and 44 (46.3%) were females. The mean of deviation angles were 53.8 ± 17.9 PD (Prism dioptres) in alt XT, 44.5 ± 12 PD in alt ET and 52 ± 13.5 PD in const ET, 47.1 ± 13.1PD in cons XT, respectively. There was no significant difference between the groups (P = 0.051). Results of surgery were in 38 patients (40%) excellent, in 31 patients (32.6%) good, in 19 patients (20%) acceptable, and in 7 patients (7.4%) unacceptable. Seven (7.4%) patients required reoperation.Conclusions:In the present study, the frequency of re-operation was much lower than other similar studies (7.4% vs. 30-50%). This suggests that the adjustable technique that used in our study can be associated with lower reoperation than other adjustable techniques used in the other similar studies.
