One hundred consecutive cases of pars plana vitrectomy with the vitreous stripper

The results of 100 consecutive cases of pars plana vitrectomy are reported. Vitrectomy was performed on accunt of complications of diabetic retinopathy (37 eyes), complicated retinal detachment (28 eyes), vitreous haemorrhage of various causes (17 eyes), vitreous haemorrhage and complications secondary to injuries (13 eyes) and secondary cataract or vitreous in the anterior chamber creating corneal dystrophy (5 eyes). With an average follow-up time of 14.2 months, vitrectomy resulted in visual improvement in 55 eyes, unchanged visual acuity in 24 eyes and reduced visual acuity in 21 eyes. The operative and postoperative complications were: secondary vitreous haemorrhage (11 eyes), retinal detachment (8 eyes), haemorrhagic glaucoma (7 eyes), retinal tears (5 eyes), lens injury (4 eyes), corneal dystrophy (2 eyes) and endophthalmitis (1 eye).     

Vitrectomy for nondiabetic vitreous hemorrhage. Not associated with vascular disease

Forty-nine consecutive eyes with nonclearing vitreous hemorrhage not associated with retinal or choroidal vascular disease underwent vitrectomy. Etiologies included vitreous hemorrhage during anterior segment surgery (22 eyes), blunt trauma (8 eyes), retinal tears with and without retinal detachment (8 eyes), Terson's syndrome (2 eyes), avulsed retinal vessel (1 eye), and idiopathic cases (8 eyes). The final visual acuity improved in 48 eyes (98%). Follow-up was 6-91 months (mean, 20 months). Of the 49 eyes, 40 eyes (82%) had a best postoperative visual acuity of 20/100 or better, 31 eyes (63%) had visual acuity of 20/40 or better, and 12 eyes (24%) had visual acuity of 20/20. The major complications included intraoperative iatrogenic retinal breaks (5 eyes), postoperative progressive cataract (7 eyes), late retinal detachment (4 eyes) and recurrent vitreous hemorrhage (2 eyes). The major complication associated with later visual loss was progressive cataract.

Comparison of intracapsular and extracapsular cataract surgery. Histopathologic study of eyes obtained postmortem

We examined 201 consecutive aphakic and pseudophakic eyes postmortem. Of these, 146 eyes had undergone intracapsular cataract extraction (ICCE) and 55 eyes had undergone extracapsular cataract extraction (ECCE), either with the posterior capsule preserved intact (ECCE-CI, 30 eyes) or having had a surgical discission performed (ECCE-D, 25 eyes). Wound-related complications were most numerous in the ICCE group, and this probably reflects the relatively recent development of microsurgical techniques. Posterior vitreous detachment was present in 84% of eyes following ICCE, in 76% of eyes following ECCE-D, and in 40% of eyes following ECCE-CI (P less than 0.001). Peripheral retinal holes were found in 8.2% of ICCE eyes, 8.0% after ECCE-D, and 3.3% of eyes after ECCE-CI. Five (3.4%) of ICCE eyes had associated retinal detachments, while no ECCE eyes had detachments. Macular edema, macular holes, and epiretinal membranes occurred in 2.1%, 1.4%, 12.3% of ICCE eyes; 4.0%, 0.0%, and 8.0% of ECCE-D eyes; and 0.0%, 6.7%, and 6.7% of ECCE-CI eyes, respectively.     

Vitrectomy for nondiabetic vitreous hemorrhage

In a group of 94 eyes with nondiabetic vitreous hemorrhage that underwent pars plana vitrectomy between March 1974 and September 1982, the causes of the hemorrhages were retinal branch vein obstruction (36 eyes), blunt trauma (11 eyes), cataract extraction (ten eyes), subretinal neovascularization (nine eyes), Eales' disease (eight eyes), Terson's syndrome (four eyes), and idiopathic (five eyes) and miscellaneous (11 eyes) conditions. Vision was improved postoperatively in 88 of the 94 eyes, including all of those that underwent blunt trauma or cataract extraction, those with Eales' disease and Terson's syndrome, and those in the idiopathic and miscellaneous groups. Final visual acuities, which depended primarily on the underlying condition and its effect on the macula, were 20/20 or better in ten eyes, 20/25 to 20/40 in 37 eyes, 20/50 to 20/200 in 26 eyes, 20/300 to 20/400 in 11 eyes, 9/200 to 5/200 in three eyes, and hand movements or light perception in seven eyes. Retinal tears, the most common surgical complication, occurred in 18 eyes. The incidence of anterior retinal tears was reduced from 11% (11 of 38 eyes) to 4% (two of 56 eyes) after we began using a vitrectomy probe with a smaller diameter. Some postoperative lens opacification occurred in 16 of 50 phakic eyes, and the incidence of later lens opacification increased as the follow-up lengthened.     

Corneal curvature and central corneal thickness in eyes with pseudoexfoliation syndrome

BACKGROUND: Previous studies have reported different central corneal thickness (CCT) values in eyes with pseudoexfoliation syndrome (PXS). There has been no report about corneal curvature (CC) in PXS eyes. The aim of this study was to investigate the CCT together with the CC in PXS eyes with and without glaucoma. METHODS: The CC (simulated keratometry 1 [SimK1], SimK2, and mean K) and CCT were prospectively studied by rotating a Scheimpflug camera in 72 PXS eyes and comparing them with 65 normal eyes. RESULTS: In all PXS eyes, the mean K was significantly steeper than in control eyes (44.1 [SD 1.5] diopters (D) vs. 43.2 [SD 2.0] D, p = 0.04). When PXS eyes were subcategorized, the mean K was significantly steeper in both normotensive PXS eyes (44.6 [SD 1.6] D) and pseudoexfoliation glaucoma (PEXG) eyes (44.0 [SD 1.2] D) than normal eyes (43.2 [SD 2.0] D) (p = 0.001 and 0.02, respectively). In all PXS eyes, the mean CCT (546.4 [SD 39.6] microm) was not significantly different than the control eyes (542.9 [SD 32.2] microm) (p = 0.56). When PXS eyes were subcategorized, however, the CCT was significantly thinner in normotensive PXS eyes and significantly thicker in PEXG eyes. INTERPRETATION: It appears that PEXG eyes have a significantly steeper CC and higher CCT than normal eyes. This could be of clinical significance because overestimation of true intraocular pressure may then occur in these eyes.

Primary diseases of corneal perforation in Shandong Province, China: a 10-year retrospective study

PURPOSE: To analyze primary diseases of corneal perforation in Shandong Province, China. DESIGN: Retrospective, noncomparative study. METHODS: Medical records of 1,056 patients (1,080 eyes) with corneal perforation treated from January 1, 1997 through December 31, 2006 at Shandong Eye Institute were reviewed retrospectively, and primary diseases were evaluated. RESULTS: Corneal perforations mainly were caused by ocular trauma 715 eyes (66.8%) and infectious keratopathy 294 eyes (27.5%). In the traumatic eyes, corneal penetrating wound accounted for 608 eyes (85.0%), followed by explosion injury 42 eyes (5.9%), thermal burn 34 eyes (4.8%), and chemical injury 29 eyes (4.1%). In the infectious eyes, the most common pathogens were herpes simplex virus 124 eyes (42.2%), fungus 74 eyes (25.2%), and bacterium 20 eyes (6.8%). Repeated corneal perforation occurred in nine eyes, with primary diseases of herpes simplex keratitis (HSK; four eyes), Mooren ulcer (two eyes), necrotizing keratitis and scleratitis (one eye), bacterial keratitis (one eye), and alkali burn (one eye). Corneal grafts perforated in 31 eyes, resulting from recurrent HSK (eight eyes), implant autoproteolysis (seven eyes), bacterial infections (six eyes), recurrent Mooren ulcer (four eyes), immunologic rejection (three eyes), trauma (two eyes), and fungal recurrence (one eye). CONCLUSIONS: Ocular trauma and infectious keratopathy dominated among the primary diseases of corneal perforation in Shandong Province, China, during the past 10 years. HSK seems to be the most common cause of repeated corneal perforation. Recurrent primary diseases and implant autoproteolysis and infection more often result in graft perforation.

Biometric studies of the eyeball and retinal detachment.

The relationship between axial length and equatorial diameter and eye volume has been studied in 4 groups of eyes: intact emmetropic eyes, emmetropic eyes with retinal detachment, eyes with moderate myopia and retinal detachment, and eyes with high myopia and retinal detachment. It was found that eyes with detached retinas, regardless of whether they are myopic or emmetropic, are of significantly different dimensions from emmetropic control eyes. There is usually a significant increase in equatorial diameter and therefore in equatorial circumference. The results indicate that eyes with detached retinas differ from normal eyes in their abnormally large size.
