Asteroid Hyalosis that Caused Decreased Vision after Cataract Surgery

PURPOSE: To report a patient with asteroid hyalosis, which induced reduction of the visual acuity after cataract surgery.CASE SUMMARY: A 79-year-old female with no ophthalmic history visited our clinic with decreased vision. Her best-corrected visual acuity in both eyes was 20/100 in the right eye and 20/60 in the left eye. She had senile cataract in both eyes, and asteroid hyalosis in the left eye. After cataract surgery, her visual acuity in the left eye decreased to finger count. There were no specific findings that could have caused the visual disturbance, except dense asteroid bodies on fundus examination. After removal of the asteroid bodies by vitrectomy, the best-corrected visual acuity of the left eye recovered to 20/20.CONCLUSIONS: In patients with asteroid hyalosis, it is possible that decreased vision may be affected by changes of asteroid body properties in the vitreous gel after cataract surgery. The vision should improve after vitreous surgery.

Comparison of Retinal Layer Thickness and Vascular Density between Acute and Chronic Branch Retinal Vein Occlusion

PURPOSE: To compare retinal layer thickness and chorioretinal vascular density (VD) between acute and chronic branch retinal vein occlusion (BRVO). METHODS: This study included patients with BRVO. The VD of the superficial capillary plexus (VDs), the VD of the deep capillary plexus (VDd), and VD of the choriocapillaris were obtained using optical coherence tomography angiography. Acute and chronic BRVO data were compared to assess differences between the involved and uninvolved areas. RESULTS: We included 17 eyes with acute BRVO and 23 eyes with chronic BRVO. The VDs in the involved area were not significantly different between the involved area and in the uninvolved area in acute BRVO (p = 0.551). However, the difference was significant in chronic BRVO (p = 0.013). The VDd in the involved area was lower than in the uninvolved area in both acute and chronic BRVO (p = 0.020, p = 0.003, respectively). In addition, the VD of the choriocapillaris values did not differ significantly between acute and chronic BRVO, or between involved and uninvolved areas. The VDs in the involved area in chronic BRVO were lower than in acute BRVO (p = 0.047), and the VDd did not differ between acute and chronic BRVO in all areas. CONCLUSIONS: Vascular impaired patterns in the retinal layer differed between acute and chronic BRVO. These results may suggest that vascular change and remodeling develops differently in acute and chronic phases in BRVO.

Infective Endocarditis Presenting as Endogenous Endophthalmitis Secondary to Streptococcus agalactiae in a Healthy Adult: Case Report and Literature Review / 감염과화학요법

Endogenous endophthalmitis secondary to group B Streptococcus (GBS) is extremely rare, particularly in healthy adults. However, the visual prognosis is poor. We report the first South Korean case of GBS infective endocarditis presenting as endogenous endophthalmitis and skin and soft tissue infection. Cultures of blood, vitreous humor, and pus from skin aspirates yielded a penicillin-susceptible serotype V strain of Streptococcus agalactiae. After 6 weeks, the patient completely recovered from GBS infective endocarditis. However, despite early antibiotic treatment and early surgical intervention, the patient's right eye developed phthisis bulbi and was a candidate for evisceration.
