To report acute onset lens particle glaucoma associated with a spontaneous anterior capsular dehiscence. A 66-year-old man presented with spontaneous anterior lens capsule dehiscence with an acute onset of right eye pain that was associated with white particles in the anterior chamber angle and intraocular pressure (IOP) of 55 mmHg. No trauma or other inflammatory antecedents were reported. A hypermature cataract was observed at slit lamp exam. After medical treatment without IOP control, we performed extracapsular cataract extraction and anterior vitrectomy. Anterior chamber aspirate confirmed the presence of macrophages. The postoperative IOP at one month was 16 mmHg OD without medication. Spontaneous dehiscence of the anterior lens capsule in a patient with a hypermature cataract may release lens cortical material, resulting in lens particle glaucoma. Prompt surgical removal of the lens material usually controls the high IOP, and the need for additional glaucoma surgery is not common.

Chronic endophthalmitis following cataract extraction and intraocluar lens implantation has been reported occasionally and Propionibacterium acnes is Known as the most common organism. This infection is often misdiagnosed as uveitis in early stage, and diagnosis depends on anaerobic culture of intraocular specimens. Intravitreal infection of antibiotics, pars plana vitredtomy, removal of IOL with lens capsule are suggested for successful treatment of chronic endophthalmitis. We report a case of Propionibacterium acnes endophthalmitis after extracapsular cataract extraction and posterior chamber lens(PCL) implantation that was treated successfully by PCL removal and intraviteal antibiotic infection.

PURPOSE: The most serious complication related to cataract surgery is endophthalmitis. Although its incidence is decreasing, it remains the great threat to the outcome of visual acuity in patients who received cataract surgery. METHODS: Retrospective analysis was performed on 18 patients who were diagnosed with endophthalmitis. The following factors were investigated: method of cataract extraction, performance of anterior vitrectomy, presence of posterior capsule rupture, results of bacterial culture, existence of systemic disease, and the duration of time from initial cataract surgery to diagnosis of endophthalmitis and then to subsequent posterior vitrectomy. In addition, the differences in final visual acuity due to variations in these factors were analyzed. RESULTS: Patients who were diagnosed with endophthalmitis and had been commenced on systemic antibiotics within a week of the cataract operation, showed better outcomes in final visual acuity (P=0.043). CONCLUSION: Occurrence of endophthalmitis and subsequent usage of systemic antibiotics within a one-week time frame of cataract surgery, led to statistically significant improvement in final visual acuity compared to cases in which these events occurred one week later.

PURPOSE: To evaluate the risk factors for cataract formation and cataract extraction after penetrating keratoplasty to determine whether a combined surgery should be performed. METHODS: Variables from 189 phakic eyes that underwent penetrating keratoplasty from April 1992 to November 2004 were analyzed for the possibility of cataract extraction after penetrating keratoplasty according to sex, age, diagnosis, accompanied glaucoma, preoperative vision and steroid use. The mean interval between penetrating keratoplasty and cataract extraction was also studied. RESULTS: Cataract extraction was performed in 27 eyes (14.3%) and the mean interval between keratoplasty and cataract extraction was 24.5 months. Age was determined to be the most important independent risk factor for cataract extraction (p=0.0009) associated glaucoma also shown to be a risk factor (p=0.0011). Sex and corneal disease before keratoplasty were not shown to be risk factors. In the mean interval cataract extraction following penetrating keratoplasty, no statistically significant difference was found according to age, sex and diagnosis. Posterior subcapsular cataract was predominant (55.6%) and the mean visual acuity improved from 0.10 to 0.42. CONCLUSIONS: The likelihood of cataract formation and cataract extraction subsequent to penetrating keratoplasty increased with age and associated glaucoma. The results from this study can help surgeons to determine whether combined surgery should be performed and help them to counsel patients on the risk of cataract formation.

To elucidate genetic traits, clinical findings and treatment outcomes in Korean families with hereditary congenital cataract, 24 patients(17 families)were retrospectively analysed. Genetic trait was analysed by family pedigree. Chief complaints, ages at diagnosis, bilaterality, types of lens opacity, associated systemic or ocular anomalies were examined. The final best-corrected visual acuity was compared among groups according to the presence of surgery or the age at diagnosis. Among 17 families, 15 belonged to an autosomal dominant trait and two an autosomal recessive trait. Bilateral cataracts were shown in all patients. Twelve(50.0%)out of 24 patients who had cataracts were diagnosed before 3 months of age. Five(29.4%)out of 17 patients who received surgery were done before 3 months of age. Final best-corrected visual acuity was not different between surgery group before 3 months of age and that of after 3 months of age. Associated ocular anomalies were microphthalmia(4 patients), nystagmus(4 patients), and esotropia(3 patients), but no systemic anomalies were found. These results show that most Korean families with hereditary congenital cataract have an autosomal dominant genetic trait and the age at diagnosis or surgery is too late to treat them properly.

We evaluated the clinical results of phacoemulsification and posterior chamber lens implantation in posttrabeculectomy eyes. 26 eyes operated during Jan. 1990 to Dec.1995 were evaluated retrospectively with preoperative and postoperative visual acuity, intraocular pressure(IOP) and antiglaucomatous agent usage.The cataract operations were done by clear corneal incisions avoiding the filtering bleb sites. The average interval between trabeculectomy and cataract surgery was 25 months. From a total of 26 eyes 11 had the diagnosis of primary open angle glaucoma(POAG) and 12 eyes chronic angle closure glaucoma(CACG). The preoperative visual acuity was 0.3 or less in 53.8%, and the postoperative visual acuity was 0.4 or better in 57.7%. The preoperative and postoperative IOPs were 14.4+/-4.3mmHg and 15.3+/-4.6mmHg respectively, showing a slight increase. Filtering bleb failure was observed in one eye in which trabeculectomy was formed twice. Antiglaucomatous agent usage decreased to 8 cases from an initial 10 cases. The preoperative IOP of the 8 cases was 17.3+/-5.1mmHg, while it was 13.1+/-3.3mmHg in the 18 cases in which the IOP was controlled without treatment. There was a significant difference between the two(P=0.03). There was a significant relationship between preoperative and postoperative antiglaucomatous agent usage(P=0.01). Taken individually, POAG showed a greater incidence of postoperative antiglaucomatous agent usage than CACG, but was insignificant(P=0.56).

PURPOSE: Perimetric examination plays an important role in the diagnosis of glaucoma, which is among the leading causes of blindness worldwide. Several examination methods have been developed for early detection of glaucoma. Among those, short-wavelength automated perimetry (SWAP) is the most widely investigated. In this study, the effects of nuclear opacities on SWAP were examined. METHODS: Lens opacities were divided into cortical and nuclear opacity groups ; each group consisted of fifteen eyes. The eyes studied underwent standard white-on-white perimetry and SWAP exams before and after cataract operation. The differences in the results of the examinations were compared between the two opacity groups. The t test was used for comparing the data. RESULTS: In the cortical opacity group, the average difference between the mean deviation before and after the operation was 5.46dB in white-on-white perimetry and 5.02dB in SWAP. In the nuclear opacity group, the average difference between the mean deviation before and after the operation was 4.01dB in white-on-white perimetry and 10.82dB in SWAP. There was no statistically significant difference in the cortical opacity group (p=0.6575). However, there was a statistically significant difference in the nuclear opacity group (p<0.0001). CONCLUSIONS: In clinical situations, more caution should be taken when interpreting the SWAP results of nuclear cataract patients in order to make an accurate decision.

PURPOSE: To compare the image quality between swept-source optical coherence tomography (SS-OCT) and spectral domain optical coherence tomography (SD-OCT), especially in eyes with media opacity. METHODS: Forty eyes without media opacity and 60 eyes with media opacity (30 eyes with cataract, 20 eyes with vitreous opacity, and 10 eyes with corneal opacity) were included in this study. SD-OCT and SS-OCT 6 x 6 macular scans were taken by a single operator. For image quality analysis, a total of 200 OCT images were subjectively graded by two trained retina specialists and measured quantitatively using the image quality factor (QF) built into the OCT devices. RESULTS: Compared to conventional SD-OCT, SS-OCT had statistically significantly better subjective and objective grades in the normal group, as well as each of the media opacity groups (p-value < 0.001). In both the subjective and objective grades, there was no significant difference according to the types of media opacity (QF: p = 0.188, subject grading scale [SGS]: p = 0.635) and the degree of media opacity (Group I: 20 < or = QF < 50, Group II: 0 < or = QF < 20; QF: p = 0.088, SGS: p = 0.051) in the superiority of image quality of SS-OCT to SD-OCT. CONCLUSIONS: In this media opacity patient population, swept-source OCT is a superior diagnostic tool when compared with SD-OCT in both objective and subjective assessments, even in the ocular media opacity. This result may be useful in diagnosis and progression detection of retinal disease in media opacity eyes.

PURPOSE: To evaluate clinical characteristics of posterior lenticonus associated with pediatric cataracts and to identify the factors associated with final visual acuities after cataract surgery. METHODS: Thirty-eight patients (46 eyes) who were diagnosed with posterior lenticonus preoperatively or during the operation were involved in this study. We investigated the age at diagnosis, the severity of lens opacity, the pre- and postoperative best corrected visual acuity, and the effectiveness of amblyopia treatment. RESULTS: The mean age at presentation was 39.0+/-37.4 months, and the mean follow-up period was 42.8+/-33.5 months postoperatively. Nine patients (23%) had bilateral posterior lenticonus, and the mean age of bilateral cases was lower (p<0.001) and the lens opacity more severe than those of unilateral cases (P=0.001). Fifteen eyes (32.6%) were surgically identified as having posterior lenticonus during lens aspiration, the mean age of surgically identified cases was lower (p<0.001) and the lens opacity more severe then those of preoperatively diagnosed cases (P=0.014). The age at initial examination was negatively correlated with final visual acuities in log MAR (P=0.04). CONCLUSIONS: Bilateral and surgically identified posterior lenticoni were associated with younger age and more severe lens opacity. The final visual acuities were better in patients with late onsets of lens opacities.
