Hospitalized patients with endogenous MRSA endophthalmitis and
unable to undergo vitrectomy may achieve a good outcome with
bedside intravitreal antibiotic injection alone

Purpose: to demonstrate that severely ill hospitalized patients with endogenous
methicillin resistant staphylococcus aureus (MRSA) endophthalmitis may
achieve a good outcome with bedside therapy alone.
Methods: interventional case series.
Results: Three patients (ages 52, 63, and 64) presented with culture proven
MRSA bacteremia and endogenous endophthalmitis. Two patients presented
unilaterally and one patient presented bilaterally. The unilateral patients were
treated with intravitreal antibiotic injection alone and the infection subsequently
cleared. The bilateral patient was treated in one eye with vitrectomy and in the
other eye with antibiotic injection alone; both eyes cleared but the vitrectomized
eye subsequently developed a retinal detachment.
Conclusion: Endogenous MRSA endophthalmitis may develop in patients with
MRSA bacteremia. These patients may be too ill to undergo vitrectomy or
vitrectomy may be unavailable at the facility. These patients may still achieve
good outcomes with intravitreal antibiotic injection alone.

Purpose The development of posterior synechia of the iris interferes with
postoperative visualization of the retina and patients› visual function. We
examined factors influencing the development of posterior synechia after pars
plana vitrectomy (PPV) for vitreoretinal disorders. Methods We retrospectively
reviewed the records of 421 eyes of 356 patients who received PPV by the
same surgeon for vitreoretinal disorders. The frequency of posterior synechia
was assessed, and multivariate analysis was performed to investigate the
relationship between various explanatory factors and the development of
posterior synechia. Explanatory factors included age, sex, operating time,
combined cataract surgery, gauge of vitrectomy system, performance of scleral
compression, number of laser photocoagulation, usage of gas tamponade,
steroid, and atropine ointment, postoperative factors (existence of vitreous
hemorrhage, anterior chamber fibrin, and hyphema). Results Posterior
synechia was found in 10.7% (45 of 421 eyes), and patients with proliferative
diabetic retinopathy showed the highest incidence (16.8%). The explanatory
factors associated with posterior synechia were operating time and number of
laser photocoagulation. Conclusion The incidence of posterior synechia after
PPV may be reduced by minimizing the degree of operative invasion to the
eye.

Purpose: To evaluate the efficiency and safety of 3 and 5-7 days preoperative
intravitreal bevacizumab administration in patients with proliferative diabetic
retinopathy (PDR).
Methods: Retrospective study for PDR patients who underwent 20 and 23G.
pars plana vitrectomy (ppv). Bevacizumab (1.25 mg/0,05 ml) was injected 3
days preoperatively in Group A (12 patients) and 5-7 days preoperatively in
Group B (14 patients). Both groups were matched for: age, diagnosis, systemic
diseases and underwent preoperative systematic controls.
Results: Vitreous haemorrhage (VH) during the operation in Group A was
present in 3/12 patients ( 25% ) while in Group B none of the patients showed
VH. First week postoperative VH in Group A was noted in 3 patients compared
to Group B with 2 patients. No retinal detachment as a complication after
bevacizumab administration was observed.
Conclusion: Preoperative intravitreal injection of bevacizumab appears to be
safe and effective way of reducing the incidence of intraoperative and early
postoperative VH. Although the study includes small group of patients and with
no significant difference between the groups we still encourage bevacizumab
administration between 5-7 days, preoperatively. Further randomised studies
should be performed to evaluate the optimal timing of preoperative drug
administration.

AIM: Efficacy and safety of non sclerotomy transpupillary Silicone Oil Removal
(SOR) and combined phacoemulsification.
Methods: In this pilot study (January- May 2010) five eyes of four candidate
patients for SOR and cataract extraction underwent transpupillary
removal of silicone oil through planned posterior capsular opening after
phacoemulsification. No sclerotomy was made and the anterior chamber
canula was used for intraocular infusion. Intraocular lens implanted at the end
of SOR and patients were followed up for 6 months. RESULTS All patients had
a favorable surgical outcome with attached retina postoperatively without any
complication.
Conclusion: This is an effective and safe technique that offers the main
advantage of diminished surgical trauma.

Multiple subretinal cysticercosis: a case report
Singh Bhupesh, Majji Ajit Babu
1. LV PRASAD EYE INSTITUTE
Purpose: To report a rare case of multiple subretinal cysticercosis Method: A
26-year-young male presented with complaints of decreased vision in the
right eye since 20 days. Visual acuity of right eye was perception of light with
accurate projection of rays and in the left eye was 20/20. Right eye anterior
segment was within normal limits and dilated fundus examination showed
localized retinal detachment with two large subretinal cysts measuring 5x6
mm with spontaneous movements on exposure to light. Clinical diagnosis of
subretinal multiple cysticercosis in right eye was made. B-scan of the right
eye showed two cysts with hyperechoic foci within the cyst suggestive of
scolex of cysticercosis. CT scan of head and orbit ruled out the presence of
neurocysticercosis. A standard 3 port 20G pars plana vitrectomy with cyst
removal was performed. Histopathology showed the parasite with 3 layers of
cuticle and protoscolex with a branching body cavity confirming the morphology
of Cysticercus.
Result: There was no significant improvement in the visual acuity due to
extensive scarring in macular area.
Conclusion: Multiple subretinal cysticercosis can be present and should be
kept in mind. Visual outcome depends upon cyst location and secondary
scarring.
