[Outcomes of heavy silicone oil tamponade in complicated retinal detachment surgery]

To evaluate the outcomes of internal tamponade using heavy silicone oil in complicated retinal detachment [RD] surgery. In this interventional case series, patients with complicated RD involving the inferior retina were enrolled. Inclusion criteria included RD secondary to proliferative vitreoretinopathy [PVR CP6 and/or CA6] involving the inferior retina, inferior or posterior tears, giant tears, penetrating trauma or RD combined with choroidal detachment. Heavy silicone [Oxan HD, Bausch and Lomb, USA] was injected at the end of surgery after peeling of retinal membranes or retinotomy. Follow-up examinations were scheduled one day, one week, one month and four months after surgery. Additional visits were made depending on the condition of the eye. Seventeen eyes of 17 patients with mean age of 45.4 +/- 12.2 [range 19-71] years underwent vitrectomy and heavy silicone oil tamponade. Mean follow-up was 11.4 +/- 3.5 [range 4-16] months. There was total RD in 10 cases, subtotal RD involving the inferior retina in 6 patients and RD associated with choroidal detachment in one. Best-corrected visual acuity [BCVA] before surgery was LP or HM in 13 eyes and counting fingers at 0.5 to 3 m in 4 eyes. During the follow-up period, the retina remained attached in 12 cases [70/5%] but 5 eyes needed further vitrectomy for reattachment. BCVA improved from 1.95 +/- 0.09 LogMAR preoperatively to 1.5 +/- 0.35 four months after the operation [P=0.045]. After 4 months' follow-up BCVA was HM in 4 eyes and 0.5 m to 20/200 in 13 eyes. Transient IOP rise occurred in one eye and silicone oil emulsification was seen in another eye. Heavy silicone oil tamponade had favorable results in terms of anatomical attachment of the retina and visual acuity

[Evaluation of correlation between severity of dry eye syndrome and retinopathy in patients with diabetes mellitus]

Diabetes is one of the most common systemic diseases. Dry eye syndrome is one of the eye involvements in diabetic patient. Evaluation of correlation between dry eye syndrome and diabetic retinopathy in patients with insipidus diabetes was the aim of this study. In this study two hundred eyes from 100 diabetic patients [non-insulin dependent] were selected and evaluated for dry eye syndrome. The patients then were divided into four groups: group 1: patients without diabetic retinopathy group 2: patients with non-proliferative diabetic retinopathy; group 3: patients with proliferative diabetic retinopathy; group 4: patients with proliferative diabetic retinopathy undergone PRPAll. The patients were examined for Schirmer test, BUT, painting cornea with flourecein and then allocated in different group based on the severity of dry eye. Collected data were analyzed by X2 and Kendle-taue tests using SPSS software. Prevalence of dry eye syndrome in patients in group 1 was 48% and in patients in group 2, 3 and 4 was 52%, 60% and 80% respectively. Dry eye syndrome is a complication of diabetes mellitus and its severity correlates with severity of diabetic retinopathy

[Bacterial contamination of donor corneas and corneal storage media received from the Eye Bank of I.R. Iran]

To determine bacterial contamination of corneas and corneal storage media provided from the Eye Bank of I.R. Iran to Rasool Akram Medical Center. This descriptive study was performed on 70 corneoscleral rims and corneal storage media. One milliliter of corneal storage media and the comeoscleral rim were sent to microbiology laboratory at the time of penetrating keratoplasty and specimens were cultured on blood agar, EMB agar, and thioglycolate broth. No organism growth was observed after 72 hours in any of 70 storage media or corneoscleral rims. The aseptic protocol of the Eye Bank of I.R. Iran is proper in term of tissue preparation, preservation, and transferring of corneal graft is proper
