Aims-To compare the rate of recurrence and complication after surgery for primary pterygium performed by one surgeon using either intraoperative mitomycin C or irradiation. Methods-A retrospective study was performed of 164 eyes in 164 patients who had undergone primary pterygium surgery. After the pterygium was excised, the bare sclera was covered by sliding adjacent superior conjunctiva. 103 eyes received intraoperative mitomycin C (0.04%, 150 seconds) and 61 eyes irradiation (total dose 21.6 Gy). The mean follow up period was 20.2 (SD 17.9) months (range 1-66 months). Recurrence was defined as the postoperative regrowth of fibrovascular tissue crossing the corneoscleral limbus. Results-The recurrence rate after mitomycin C and irradiation was 8.74% and 23.0% of eyes, respectively, after mean follow up of 17.9 and 31.2 months, respectively. The Kaplan-Meier survival analysis revealed a significantly better outcome for those who had intraoperative mitomycin C (Mantel-Cox log rank analysis, p=0.031). The mean interval to recurrence was not significantly diVerent between the two groups. During the follow up, none of the patients showed side eVects or reactions related to mitomycin C or irradiation. Conclusions-The intraoperative administration of 0.04% mitomycin C is more eVective than irradiation as an adjunctive treatment for pterygium surgery in the patient population examined in this study. (Br J Ophthalmol 2000;84:618-621) Since pterygium frequently recurs after simple surgical removal, numerous surgical procedures and adjunctive measures have been devised to prevent the recurrence, including a sliding conjunctival flap to cover the pterygium excisional site,

Objective: To confirm the effect of a square-edged, closed endocapsular equator ring (E-ring) for preventing posterior capsular opacification (PCO) after cataract extraction. Methods: Fifty-one eyes underwent cataract surgery associated with E-ring implantation between October 2002 and March 2008. Group 1 included 14 patients (14 eyes) who received an E-ring and intraocular lens (IOL) in 1 eye before March 2006. Their fellow eyes received only an IOL as controls. Group 2 included 23 patients (37 eyes) who received an E-ring and IOL in 1 or both eyes after March 2006 and another 37 age-matched control eyes with only IOL implants. After cataract removal, the E-ring (1.0 mm wide and thick and 9.0 or 9.5 mm long) was implanted in the capsule and an IOL was fixed in the ring. In the control eyes, only an IOL was implanted. The follow-up periods were 2 to 7 years. The PCO value was determined using the Hayashi method. Results: Two years postoperatively in group 1, the PCO value in the central area of the eyes with an E-ring was significantly lower than in the controls (4.4 vs 11.4, respectively; P=.005). No eyes with an E-ring required Nd:YAG laser posterior capsulotomy postoperatively compared with 23 of 51 control eyes (45%). The posterior capsule in the eyes with an E-ring remained transparent without touching the IOL optic. The 9.5-mm ring fit all eyes. Conclusion: The 9.5-mm E-ring, which fit all eyes, prevented PCO in human eyes 2 to 7 years postoperatively.

Background Klebsiella pneumoniae endophthalmitis is rare and despite immediate management, visual outcome is generally poor. We report a case of endogenous K. pneumoniae endophthalmitis that was treated successfully. Case An 80-year-old woman with a liver abscess was diagnosed at an early stage with endogenous K. pneumoniae endophthalmitis. She underwent par plana vitrectomy and lensectomy within 8 h after the onset of ocular symptoms. Secondary implantation of a sulcus-fixated intra-ocular lens (IOL) was performed 12 months later. Final visual acuity OS was 20/20. Conclusions The present case highlights the potential benefit of early and broad vitrectomy with lensectomy in the management of endogenous K. pneumoniae endophthalmitis.

The standard 9.5-mm-diameter closed E-ring does not prevent extensive PCO in eyes with preoperative myopia ranging between -8.75 and -12.5 D and an axial length between 25.86 and 29.97 mm. Posterior capsulotomies were performed safely. Further study is needed to determine why PCO did not occur in more high myopic eyes (larger axial length eyes).
